Definitions

the invention relates to a roller straightening machine for elongated workpieces acc. the preamble of claim 1.
the straightening rolls are regularly rotatably mounted in roll holders about their longitudinal axis and, in the case of inclined roll straightening machines, can additionally be pivoted about an axis in the transverse plane of the straightening material.
At least one roll holder is adjustable transversely to the longitudinal extent of the straightening good, i.e. movably guided in the machine frame in order to be able to adjust the leveling machine to the dimensions of the leveling material.
roller straightening machines it is known to secure at least one roller against overload.
the roll in question shifts in the event of an overload in a direction transverse to the longitudinal extent of the material to be straightened.
Such a straightening machine is known from DE-PS 1910878.
the lower roller of a 2-roller straightening machine shown there is mounted on a slide that is pressed hydraulically against the workpiece.
the problem with overload protection is that the rigidity of the straightening machine must not be affected by the overload protection.
the invention has for its object to simplify the overload protection for rolls of roll straightening machines.
the roller holder is designed as a rocker which, when an overload occurs, recedes on the side facing away from the joint against the force of the spring and thereby releases the path of the material to be straightened.
a prerequisite for the invention is the knowledge that the overload of the straightening machine is regularly due to a slight excess of the straightening good. Straightening goods that are much too “thick” can be easily recognized and do not fit between the intended insertion funnels or rulers on 2-roll straightening machines and therefore do not even get between the straightening rolls themselves. Overloading by workpieces that are too "thick” can result therefore be excluded.
the present invention seeks to find a way out for oversize workpieces, e.g. only 1 mm.
the embodiment of the invention according to claim 3 allows the entire roll holder to be clamped firmly to the machine frame without additional structural effort by the tie rod and the spring.
the embodiment of the invention according to claim 4 ensures that the evasive movement of the roll takes place approximately in the transverse direction to the straightening good.
the arrangement of the joint and spring between the roller holder and is preferred Machine frame provided.
the force required for the spring is approximately halved by designing the roller holder as a rocker.
the feature of claim 5 offers the possibility of connecting the spring to an existing hydraulic station.
the feature of claim 6 serves a wide support of the roll holder on the machine frame and a further reduction in the pressure required for the individual hydraulic spring.
Claim 8 serves to simplify the construction of the joint.
the joint is arranged in the area of the longitudinal end of the straightening roller secured against overload. He is assigned one foot each on the straightening roller carrier, which lifts it from the machine frame, so that there is a space between the straightening roller carrier and the machine frame, which opens up the possibility that the straightening roller carrier will be overloaded at the opposite longitudinal end on the outlet side, where the spring is arranged , can lower.
roller or its carrier to be lowered at different longitudinal sections. It is possible that only the end of the roll on the inlet side is lowered and only then the end on the outlet side. The force to lower one end of the roll is less than the force to lower the entire roll.
the joint is formed in the case of lowering of the roller on the inlet side by the springs supporting the roller carrier on the outlet side in cooperation with the ball pins and the stops.
FIG. 1 shows a 2-roller straightening machine 1, in which the machine frame 6 consists of an upper crosshead 21, a lower crossmember 22 and four columns 23 to 26 arranged in the four corners of the crosshead and crossbar.
the straightening rollers 2, 3 have intersecting axes in a plan view.
the columns 23 to 26 connect the upper crosshead 21 to the lower crossmember 22.
a roller holder 4 is arranged on the lower crosshead 21. It is pivotable and displaceable in the vertical direction in the crosshead 21.
a roller holder 5 is clamped on the lower crossmember 22 between the columns 23 to 26. It consists of one Base plate 17 and a fork piece 18 in which the straightening roller 3 is rotatably mounted. As indicated in FIG. 2, 28 rulers 30, 36 are provided laterally next to the workpiece, which prevent the workpiece from laterally deflecting between the straightening rollers 2, 3.
the workpiece 28 moves on a helical path between the straightening rollers 2, 3 and the straightening rulers 30, 36 in the direction of the arrows 29 and 37 through the straightening machine 1.
the swivel adjustment of the two roller holders 4, 5 is used to adjust the deflection of the workpiece 28.
the fork piece 18 of the lower roller holder 5 can be adjusted relative to the base plate 17 against the base plate 17 carrying it by means of the swivel adjusting device 27.
the lower roller holder 5 of the 2-roll straightening machine 1 can be pivoted by a few angular degrees in order to prevent the straightening machine from being overloaded against the machine frame 6. With this pivoting movement, the distance between the straightening rollers 2, 3 increases.
the straightening machine makes the slightly "thick" workpiece 28 between the straightening rollers somewhat more space and thus avoids overloading the machine.
the roller holder 5 has on the longitudinal side 13 of the roller 3 facing the incoming workpiece a joint 7, which consists of two feet 32, 33 on the roller carrier 5 and each on a machine frame arranged ball stud 19, each in a cylindrical bore 20, 31 on the roller holder 5 intervenes.
the two ball journals position the roller carrier on the lower crossmember 22.
Two hydraulic springs 8, 16 are arranged on the longitudinal side 12 of the straightening roller 3 facing the outgoing workpiece in the region of the longitudinal ends 40, 41.
a stop 9 which is designed as a tie rod and which is used to lift the lower roller holder 5 off the base plate avoids under the force of the springs 8, 16.
the tie rod 38 shown as a screw is rigidly connected to the lower cross member 22 and serves the roller holder 5 as a stop 9.
the springs 8, 16 press the roller holder 5 in the working direction of the roller 3 against the stop 9.
the stop is approximately in the middle between the spring 8 and the joint 7 arranged.
the lower roller holder 5 is braced with the crossmember 22 by the springs 8, 16, the feet 32, 33 and the stop 9.
the spring is a hydraulic cylinder 39 which is connected to a pump 15 and to a pressure relief valve 14.
the pressure relief valve allows easy adjustment of the pressure to the maximum straightening force required.
the piston of the cylinder 39 withdraws.
the roll holder 5 with the roll 3 lowers substantially on the outlet side of the workpiece and thus widens the straightening gap to the extent necessary to avoid the overload.
the arrangement of the joint 7 on the inlet side of the straightening machine and the springs 8, 16 on the outlet side of the same results in an advantageous evasive movement of the straightening roller 3, which both follows the direction of advance of the workpiece 28 and at the same time expands the straightening gap.
a support of the base plate 10 on 4 leaf springs 42, 43, 44, 45 is shown. These springs press the base plate against three stops 46, 47, 48 and thus secure their position in the desired position in the direction of the straightening force.
two ball pins 49, 50 are provided, which project from the lower cross member of the machine frame 6 and which secure the position of the base plate 10 in the transverse direction to the straightening force.
the base plate 17 is pivoted relative to the path 37 of the workpiece in accordance with the average operating angle of the straightening rollers 2, 3 in the machine frame 6. This ensures a defined lowering of the lower straightening roll 3 in the embodiment according to FIGS. 1 and 2.
an intermediate space 11 is provided between the base plates 10 and 17 on the one hand and the machine frame 6 on the other hand, which allows the secured straightening roller to evade against the machine frame.
