Definitions
- the invention relates to a method and an apparatus, in particular a roll stand, for the production or recalibration of metal profiles, in particular rolled steel profiles, with a tightly tolerated chamber dimension.
- the invention also relates to a rolled section produced by the method according to the invention.
- chamber dimension means the dimension between the inside of a first flange and the inside of a second flange opposite the first flange of the metal profile.
- the invention thus relates in particular to the production or recalibration of U or double-T profiles, but also the adaptation of the chamber dimension of other profile geometries, in which two substantially parallel flanges are opposite, can be made meaningful by the invention.
- Metal profiles with two substantially mutually parallel and opposing flanges are well known.
- increased demands are placed on the chamber dimension tolerances, in particular when the opposite inner sides of the flanges form functional surfaces which functionally interact with adjacent components, for example with rolling elements.
- Such applications are known, inter alia, from the conveyor industry.
- monorail rails such increased demands are made.
- hoisting masts for the construction of lift masts for industrial trucks, in particular for forklifts.
- a plurality of metal profiles are arranged interleaved and telescopically movable against each other for raising or lowering the stacked goods in the profile longitudinal direction. Between the individual metal profiles are rollers as rolling elements.
- any play between the metal profiles and the rollers allows a pivoting of the metal profiles against each other transversely to the profile longitudinal direction or to the vertical lifting direction. Even a small clearance between the rollers and the area of the surface of the metal profile on which the rollers roll, can have a strong impact especially at high lifting heights.
- a stackable item located at a high height which often has high weight, must not or only extremely slightly stagger transversely to the vertical stroke direction, so as not to jeopardize the stability of the vehicle or the overall structure and the exact positioning of the item to be transported in a rack storage not unnecessarily complicate.
- the profiles can be subsequently pulled.
- the pulling of mast profiles ensures a good parallelism of the flanges, tight dimensional tolerances, smooth surfaces and a favorable work hardening of the material.
- the profiles also have a low tendency to wear, show only a small inlet effect and can be well welded.
- a disadvantage is the high production costs and the associated high production costs, which is why drawn profiles are not really competitive.
- the brittle resistance of drawn profiles is significantly worse than profiles that are produced in other ways.
- the pulling can also lead to an increased profile distortion (bending, twisting), which is then again consuming to correct in a straightening machine.
- the object of the invention is therefore to provide a method for the production or recalibration of metal profiles and an apparatus for performing such a method, which combines the advantages of the known methods described above as far as possible.
- a method and a device are to be provided with which in particular lift mast profiles with parallel flanges, narrow tolerances and high material strength with respect to wear can be produced.
- the aim is a mast profile that eliminates the need for several roller sizes when constructing a mast, that is characterized by good wear properties, weldability and brittle fracture, has good run-in behavior and can still be produced at a lower price than milled mast masts.
- the device according to the invention or the method according to the invention makes it possible in particular to recalibrate pre-rolled profile blanks by means of rolling in the temperature range of cold forming.
- a high flange parallelism tight chamber dimensions tolerances and a targeted and defined workable strain hardening of the material in the area of H ubmastprofilen particularly stressed, near-surface flange inner sides are achieved.
- the brittle security is good.
- the surface quality of the flange inside is due to the fact that any bumps or grooves are compensated or smoothed by the hot rolling process by taking place on the flange inside rolling process, good.
- the manufacturing costs are well below those manufacturing costs incurred by machined profiles after machining.
- the inner work rolls are made of a high-strength material, in particular a high-tempered steel (for example 100 Cr 6) or a load-bearing ceramic material and in each case with a high surface quality.
- Each inner work roll is regularly assigned a support body. This supports the force exerted by the respective inner work roll on the Profilflanschinnenseite U forming forces on the respective flange outside.
- the supporting bodies are preferably formed by a first supporting roller and a second supporting roller and, like the inner working rollers, are rotatably mounted in the rolling stand.
- support rollers and other types of support body can be used.
- the choice of the support body depends inter alia on the way in which the metal profile and the roll stand are moved relative to each other.
- Age- native to the support rollers which are preferably used when the metal profile is moved relative to a stationary rolling mill or when the inner work rolls are moved together with the support rollers relative to a fixed clamped metal profile, the use of plate-shaped support bodies can be provided which bear against the flanges on the outside and support the forming forces acting on the flange inner sides by the work rollers. The metal profile can then be firmly clamped between the externally applied supporting bodies and held by them.
- the support body are preferably formed by elongated, plate-like bodies or support rails, which are employed with a flat contact surface against the flange outer sides and supported the forming forces.
- the support body or support rails may extend in this case over the entire length of the metal profile to be machined.
- a support body of a plurality of hingedly interconnected individual plates which cooperate with each other in the manner of a tank chain.
- These so interconnected individual plates can also either exert the necessary feed forces on the metal profile to be moved to move this relative to a fixed pair of work rolls, or move as part of the rolling stand with this and are preferably used, the required feed forces on the to transfer relative to the fixed metal profile moving pair of work rolls.
- working gap is to be understood to mean that the forming work is largely done by the force exerted by the inner work on the flange inner sides forces and the support body, the forces exerted by the inner work on the Flanschinnencons forces only outwardly supported to a lateral deformation or
- the spacing of the supporting bodies is matched to the distance of the flange outer sides, the deformation and the concomitant achievement of the desired chamber dimension can be achieved by these measures are achieved as a result of an actual localized reduction of the flange material thickness by plastic deformation of the flange material located near the surface of the flange.
- the Support bodies are dimensioned such that they cause such a low surface pressure between the flange outer side and support body when using the device as intended, that no appreciable plastic deformation of the flange located near the flange outside flange material takes place.
- the invention allows By using manufacturer-specific inner work roll forms, the surface of the inside of the flange can already be adapted to the manufacturer-specific rolling element or roll geometry used when producing the lift mast profiles.
- the inner work rolls have a non-cylindrical outer contour in the region of the contact surface formed between the inner work roll and the inner side of the flange when the device is used as intended. The outer contour of this contact surface can be reflected during the process of cold deformation on the flange inside.
- U forming the metal profiles to the desired chamber size can be done both before introducing the metal profile in a roller straightening or between individual Rollenrichtvor réellen.
- the U forming the metal profile to the desired chamber size before a final passage through a roller leveler and / or a final reworking in a straightening press is particularly useful because it can not always be ruled out that uneven degrees of deformation occur, for example, a twisting or bending of the metal profile could result, which would be compensated by a roller straightening machine and / or a straightening press again.
- the rolling stand can also be integrated in a roller leveler. In this case, the roll stand should be movable within the roller leveler to compensate for any movements of the metal profile transverse to the profile longitudinal direction can.
- the inner work rolls which rotate about a rotation axis, preferably acted upon by a force acting in the direction of the rotation axis and the inner work rolls in the direction of the profile web pressing force, which ensures that the inner work rolls in the transition from flange to the web of the metal profile always good abutment or at least kept at a defined distance to the web.
- the optionally manufacturer-specific deformation exerted by the inner work rolls on the flange inside remains constant in the profile longitudinal direction. An emigration of work rolls away from the surface through the profile bridge defined level to the profile exterior can be excluded.
- This pressing force can of course also or additionally be provided by a pressure roller, which is arranged on the working roll pair side facing away from the metal profile and hires the metal profile against the pair of work rolls to prevent the metal profile in the process relative to the pair of work rolls away from this.
- a spacing element which keeps the inner work rolls at a defined distance from the web surface despite the pressing force urging in the direction of the profile web.
- a spacer may be formed by a spacer roller or other rolling elements, which roll or slide gently on the web surface during the process of the profile relative to the rolling mill.
- the device has a first cleaning device, which cleans areas of the metal profile of impurities before they enter the mill stand.
- impurities can be created by scale, which flakes off the profile surface in upstream process steps.
- the cleaning device may in particular blow off the contamination with compressed air, rinse with water or remove by brushing or a combination of these operations.
- the cleaning process preferably takes place continuously during the process of the metal profile relative to the roll stand.
- the rolling process can be carried out in multiple stages, in particular if the degree of deformation required for the desired chamber size is so high that it can only be achieved with difficulty by means of a single passage.
- the metal profile can either be guided several times through one and the same roll stand or else it can be guided. NEN several rolling stands are traversed one behind the other, wherein the force exerted on the metal profile pressure or the inner work roll and / or working gap geometry can be gradually adjusted.
- a device for removing the rolling bead in particular a planer, can be arranged on the rolling stand or on the device in which the rolling stand is embedded.
- the inner work rollers can be provided to ensure the process of the rolling stand and the metal profile relative to each other.
- the outer supporting bodies are formed by motor-driven supporting rollers.
- the aforementioned pressure roller can be driven alternatively or in addition to working and / or support rollers.
- FIG. 1 is a front view of a rolling stand, are passed in the flanges of a metal profile between inner work rolls and outer support rollers, and Fig. 2 shows the arrangement of Figure 1 in a plan view,
- FIG. 1 shows a frontal view of a rolling stand 10 forming the device according to the invention, in which flanges 21, 22, 23, 24 of a double T-shaped profile 20 chosen here by way of example pass between inner work rolls 11, 12, 13, 14 and outer support rolls 15, 16 become.
- Flanges 21 and 23 are each a first flange according to the invention and flange 22 and 24 are each a second flange in the context of the invention.
- the inner work roll 11 forms a first inner work roll and the inner work roll 12 forms a second inner work roll in the sense of the invention. Together they form an inner pair of work rolls arranged between flanges 21 and 22. Accordingly, the inner work roll 13 forms a first inner work roll and the inner working roll 14 a second inner work roll in the context of the invention, which together form another inner pair of work rolls, which is disposed between the flanges 23 and 24.
- a first support roller 15 acts from the outside on the flanges 21 and 23 and a second support roller 16 acts from the outside on the flanges 22 and 24.
- the configuration shown in Figure 1 thus shows two within the meaning of the invention first inner work rolls 11, 13 and two in According to the invention second inner work rolls 12, 14th
- First inner work roll 11 and first outer support roll 15 form between them a first working gap
- a second inner work roll 12 and second outer support roll 16 form between them a second working gap.
- first inner work roll 13 and first outer support roll 15 form between them a first working gap in the sense of the invention
- second inner work roll 14 and second outer support roll 16 form between them a second working gap in the context of the invention.
- a total of four working gaps are shown, namely two first working gaps in the sense of the invention and two second working gaps in the sense of the invention.
- Figure 2 shows the configuration of Figure 1 in a plan view.
- the outer support rollers 15 and 16 and the inner work rollers 11 and 12 rotate in the direction indicated in Figure 2 by the rotation arrows directions.
- the metal profile is moved in a feed direction V relative to the rolling stand.
- the mill stand can be moved relative to the firmly clamped metal profile.
- the flange inner sides are in the region in contact with the inner work roles com men and will roll on the later use as a mast profile rolling elements to a chamber dimension K 0 spaced from each other.
- the metal profile 20 also has a web height So.
- the inner work rolls exert forming forces on the flange inner sides and lead to a cold forming on the flange inner sides and thus to a near-surface work hardening and to a surface smoothing.
- 20 force arrows Fy are shown in the upper chamber of the double T-profile, which indicate how the forming forces acting transversely to the longitudinal direction of the profile cancel each other out between the flanges 21 and 22. Only the forces acting on the flange outside by the support rollers 15 and 16 must be absorbed by the bearing of the outer support rollers (not shown). This is achieved in that the inner work rolls 11 and 12 roll on each other and therefore the forces occurring directly on each other support.
- the force arrows F A likewise drawn in FIG. 1 illustrate a contact force acting in the direction of the rotation axis R on the working roller pair, which ensures that the working roller pair can not move upwards in a movement directed away from the profile web 25.
- each inner work roll will have a nominal diameter of Vi Ki, ie half the desired final chamber dimension Ki.
- the nominal diameter is optionally increased by a surcharge, which takes into account that the flange material and the material of the inner work rolls themselves have a certain elasticity material and even when exposed to the U molding forces even to a small extent elastic, ie without remaining plastic deformation, give way and then spring back again , The actual diameter can therefore be slightly larger than the nominal diameter Vi Ki.
- the inner work rolls can have a non-cylindrical outer contour at least in the region in which they are in contact with the flange inner sides during the forming process.
- the inner work rolls are drawn illustratively cambered. So they have a cross-section like an outside curved positively the convex Sam mellinse.
- other cross-sectional shapes in particular also a cross-section such as an externally negatively curved, concave diverging lens, or unsteady outer contour profiles are conceivable in principle. This makes it possible to consider certain manufacturer-specific roll shapes, which may already be in the manufacturing process, and to map their outer contours in the flange inner sides.
- the non-parallelism can both be such that, starting from the web, a closing chamber dimension results (the effective outer diameter of the inner work rolls decreases in a direction away from the web surface), and be such that starting from the web an opening chamber dimension results (the effective outer diameter of the inner work rolls increases in a direction away from the web surface direction).
- the method or the rolling stand in hot-rolled steel profiles, allows the flange inside sides, which typically originate from the web, to be formed in such a way that they subsequently run parallel, but not parallel but opening.
- FIGS. 3a, 3b and 3c again illustrate the forming process.
- FIG. 3a shows the metal profile cross-section before entry of the flanges into the working gaps.
- the near-surface material areas on the inner sides of the flange, which are machined during the process or in the roll stand, are illustrated in FIG. 3b by the areas which are deposited in black.
- 3c shows the cross section of closing Lich Hubmastprofil with which modified by bridecrotone K 0 to the desired Endclot Ki chamber dimension.
- the diameter of the outer support rollers is considerably larger than that of the inner work rolls, so that the surface pressure is kept low on the flange outside.
- the contact area with the outer surface of the profile flanges in particular ensures a sufficiently low surface pressure to prevent plastic deformation on the flange outside, if the effective diameter of the support body at this point about 700 mm to 750 m m or more.
- this is not to be understood as a rigid value.
- deviating values can also yield meaningful results.
- the support body does not necessarily have to be formed by a support roller. They can also be formed, for example, by a plate or rail with side stop or by a plurality of hingedly interconnected individual plates, which are connected to each other in the manner of a tank chain and form a flat, flat support surface.
- the choice of the support body shape will depend, among other things, whether the rolling stand is moved relative to a stationary metal profile tense, or whether the rolling stand is installed stationary and the metal profile is moved relative to the rolling stand. Especially in the latter case, it makes sense to drive the inner work rolls and / or the support body, if they are designed as support rollers, motor. Who- driven both support rollers and inner work rolls, of course, to ensure synchronization of the surface speeds.
- the first and the second support body can of course also be formed by a single component, which supports the forming forces on both sides, that is to say both on the first and on the second flange.
- Figure 4 illustrates a particular embodiment of the rolling mill according to the invention or the method according to the invention, in which the angle a, the imaginary connecting axis A, which connects the centers of the two inner working roles thought of each other, includes with the profile longitudinal side or the feed direction V is increased.
- the angle is adjusted from an angle of less than 90 ° to an angle of substantially 90 °.
- the force acting on the flange inner sides, effective outer working dimension of the inner work rolls is increased or narrowed at constantly spaced outer support rollers of the working gap gradually.
- the outer support rollers which, of course, are actually to be provided in order to form the working gap together with the inner work rolls 11, 12, are not shown in FIG. 4 for the sake of clarity.
- such a configuration offers the possibility of changing the chamber dimension gradually, starting from the initial chamber dimension K 0 (as yet unprocessed metal profile) to the final chamber dimension K 3 .
- the axis Ai includes an angle ⁇ with the profile longitudinal side or the feed direction V, to extend the chamber dimension K 0 to the chamber dimension Ki.
- the angle ⁇ is widened to the angle 0.2 in order to narrow the working gap somewhat and thus to widen the chamber dimension Ki to the chamber dimension K 2 .
- the angle 012 is widened to the angle a 3 in order to narrow the working gap once more and thus to expand the chamber dimension K 2 to the chamber dimension K 3 , which then represents the final chamber dimension in the example illustrated in FIG ,
- the necessary or meaningful number of passes and thus the number of alignment changes of the inner work roll pair or the number of working gap narrowing for the particular application can be determined.
- the angle ⁇ is increased stepwise to gradually narrow the working gap, which is otherwise kept constant for each pass.
- the skew of the rollers shown in Figure 4 with respect to the feed direction so the adjustment of the imaginary connection axis A and the concomitant narrowing of the working gap, but can also be used to compensate for any differences in the Kammergestion that can exist on the metal profile length compensate.
- at the beginning or end of the metal profile can be adjusted in a limited area due to the entry or leakage of the metal profile from the working gap slight deviations from the lockable in the middle of the metal profile chamber dimension.
- the inclination of the inner work rolls to the feed direction shown in Figure 4 can thus not only be gradual for several runs, the inclination is kept constant for each pass, but can also be selectively changed during a run to any differences in a measured Ist-Kammerment targeted to level along the metal profile.
- a measuring device which detects the actual chamber dimension during a passage.
- the measuring point or In this case, the measured value preferably leads the working gap, so that after detecting a deviation, it is possible to react directly by adjusting the angle ⁇ .
- the measuring point or the measured value lags the working gap or that both a leading and a lagging measured value are detected.
- the latter has the particular advantage that the system by adjusting the angle ⁇ directly detect the achieved by this adjustment Kammerhusterung and programmatically readjust or correct.
- the maximum amount that can deviate the angle ⁇ of 90 °, ie the degree of inclination of the axis A to the feed direction V, will differ depending on the material of the metal profile and depending on the set stitch loss and is to be chosen so that a sufficient support of inner working roles remains ensured and that the resulting torque with which the forces acting on the inner work rolls forces to push them into an even stronger inclination remains manageable.
