Definitions

  • the invention relates to a wire bending machine with a central mandrel determining the bending axes and the radius of curvature, a shearing device arranged within the central mandrel and a retractable and extendable bending mandrel which can be moved on a circular path around the central mandrel by means of a bending plate, and a method for operating such a device.
  • a wire bending machine of this type is known, inter alia, from CH-A 592 481.
  • the machine described therein has the particular disadvantage that the bending mechanism cannot be adapted to different wire or rod cross sections, as is necessary, for example, when bending reinforcing bars in accordance with SIA standards.
  • the rapid changeover of processing to different bar cross-sections is a requirement for the economical use of such machines. It is therefore the task of creating a bending machine of the type mentioned at the outset, which allows the individual elements and the operating sequence to be rapidly adapted to the material to be processed.
  • This is achieved according to the invention in that the central mandrel and the shearing device together form an exchangeable one. Form a unit to adapt to changing wire diameters or radii of curvature.
  • a plurality of openings for receiving the bending mandrel are distributed at different intervals in order to adjust the radial position of the bending mandrel over the bending plate.
  • a cover plate with a radial recess for the bending mandrel preferably has a position-determining element which allows the angular position of the bending mandrel to be determined. With two sensors, which respond to the position determining element, an initial angular position can be determined in this way for each radial position of the bending mandrel on both sides of the wire feed device.
  • a method for its operation is characterized in that the bending mandrel is moved back in one of its two initial angular positions after execution of a bending in the retracted position and with simultaneous wire feed.
  • Fig. 1 shows in connection with Fig. 2 the basic structure of the wire bending machine.
  • the directional wire reaches the bending and shearing point 1 through a fixed wire feed channel 5 connected to the machine housing.
  • a bending mandrel 3 is the wire feeding direction by means of a rotatably driven bending plate 4 with respect to each 180 0 in the clockwise and counterclockwise.
  • the bending mandrel 3 penetrates the bending plate 4 and is screwed into a fastening disk 6 located behind it.
  • This is axially displaceable in guide members 7 (FIG. 3) with respect to the bending plate 4, as shown in broken lines in FIG. 1, as a result of which the bending mandrel 3 can be withdrawn from its working position.
  • the axial displacement of the mounting disc 6 takes place via an oil-hydraulic lever system, not shown.
  • the torque required for the bending is exerted by the bending plate 4 on the bending mandrel 3.
  • the bending plate 4 has a hollow cylindrical rear attachment, on which a drive gear 9 is seated between bearings 8 and is driven by a kinematic chain, which is not shown in detail.
  • the mandrel can independently perform a circular movement and an inward or outward movement. This will be explained in more detail later in connection with FIG. 5.
  • a shearing and ejection device 10 Arranged within the central mandrel 2 is a shearing and ejection device 10, which has an axis Direction with a certain stroke movable shear tool 12 which is driven via an actuating rod 13 by a hydraulic cylinder 11 (Fig. 1).
  • the shear tool 12 which has a reinforced flat shear surface, interacts with a sleeve 14 in the central mandrel 2, which is designed on the one hand as a wire guide and on the other hand as a counter knife.
  • the central arrangement of the shearing device 10 has the advantage that for the formation of the end section of a fully bent wire bracket, no retraction of the wire is necessary in the case of short end sections, as is the case with known bending machines, which have a shearing device arranged in front of the bending point.
  • a central arrangement of the shearing device hitherto prevented the bending machine from being adapted to the respective needs.
  • the bending radii which are primarily determined by the shape of the shaping jaws of the central mandrel 2, should be able to be adjusted depending on the wire or rod diameter (see the corresponding SIA standards).
  • the aforementioned adaptation of the bending machine therefore requires, among other things, easy interchangeability of the central mandrel 2, within which, as explained, the shearing device 10 is arranged.
  • the central mandrel is provided on the back with a hollow shaft 15, as can be seen in FIGS. 2 and 3.
  • the hollow shaft 15 has a thread 16 at the rear end, in which a corresponding mating thread of a holding tube 17 engages.
  • the holding tube 17, which is rotatably held in bearings 18, has a worm wheel 19 which can be driven by the motor 21 via a worm 20 (FIG. 1).
  • Another one A hand crank is provided, by means of which the worm 20 can be rotated by hand. If the central mandrel is to be replaced, the motor 21 is started up or rotated on the hand crank, as a result of which the holding tube 17 is set in rotation. Since the central mandrel and thus the hollow shaft 15 is secured against rotation by the wire feed channel 5, but is axially displaceable, the screw connection between the holding tube 17 and the hollow shaft 15 is loosened and the central mandrel 2 moves outward. The shear tool 12 is now connected to its actuating rod 13 (FIG.
  • the shear tool 12 is loaded to the rear by means of a spring 22. Its connection to the actuating rod 13 is ensured by radially displaceable bolts 23 which, when the hollow shaft 15 is advanced, are pressed into radial recesses 24 arranged therein by the spring force and thus release the connection.
  • a locking ring 25 ensures that the heavy tool 12 can be pulled out together with the central mandrel 2 after the screw connection has been completely loosened.
  • the insertion of another central mandrel 2 together with. a shearing tool 12 is done in a corresponding manner, the motor 21 being operated in the opposite direction of rotation.
  • Central mandrel 2 and shear tool 12 also form a unit insofar as they together form the shaping jaws, as can be seen in particular from FIG. 2.
  • the shaving tool 12 has guide projections 26 on the shaving head, which form part of the shaping jaws and are adapted to the radius of curvature thereof.
  • the cover plate 29 is otherwise freely rotatable with respect to the bending plate 4. In the area of the radial slot 30, it has a metal plate as position determining element 31 for influencing proximity switches 32, 33. Two such proximity switches 32 are arranged in particular to determine two starting angular positions for the bending mandrel 3 in the wire feed direction behind the central mandrel and to the side of this feed direction, while two further switches 33 are located on both sides of the wire feed channel as a fuse.
  • the radial position of the mandrel 3 is now changed by aligning the cover plate 29 with the suitable threaded hole 27 in the mounting plate after removing the mandrel 3 and screwing the mandrel back into place.
  • the position determining element 31 is in any case aligned with the new position of the bending mandrel 3, which means that it can be automatically brought back into the correct starting positions by means of the proximity switches 32, so that no readjustment of the device is necessary.
  • FIG. 4 in front of the bending and shearing point 1 there is first a straightening and transport device 34 consisting of several rollers, which is only shown schematically. This device straightens the wire material drawn off a roll and ensures its controlled feed. The straightening and transport device is followed by a length measuring roller arrangement 35. This determines the exact amount of the feed for the control device of the machine. The legs and section lengths of the wire brackets to be produced are determined solely by the size of the feed, as can now be seen from the individual phases of a typical operating sequence shown in FIGS. 5a to 5x for forming an S-shaped bracket. According to FIG.
  • a wire feed (in the direction of the arrow).
  • the amount of feed must exceed the distance between the central mandrel 2 and the bending mandrel 3.
  • the latter is, for example, on the upper of its two starting positions mentioned and is ready for a clockwise bend. 5b at an angle of 90 °.
  • the bending mandrel is turned back by a small angle, so as to release the wire, which exerts a spring-back force on the bending mandrel, so that the latter can retract from an active position without friction (FIG. 5d).
  • the wire is then shifted and the retracted mandrel is returned to its upper starting position.
  • the wire is released (Fig. 5 c, h, n etc.), after which the zoned mandrel returns to one of its two initial angular positions with simultaneous wire feed, depending on which bending direction is to be carried out subsequently . It is essential that these starting positions even after the central mandrel 2 or the shearing device has been replaced 10 and when moving the bending mandrel 3 unchanged, without a readjustment being necessary.
  • step 5 c (and corresponding) is omitted, i.e. Loosen and pull back simultaneously.
  • step 5e can be divided into two individual steps, namely first wire feed and then turning the bending plate.
  • the arrangement described allows the bending machine to be adapted to the wire or rod material to be processed within a very short time. This can significantly increase the machining efficiency.
