Description

The chain of the invention is technologically expandable; capabilities by increasing the range of manufactured parts.

This chain is achieved in that the device for the manufacture of reinforcing products comprises a central bending mechanism arranged in the form of bending rollers and a punch, a flat-bending mechanism. The movement of the bending ends of the workpiece in the form of carriages mounted in the yurpus guides is connected with the mechanism to them. the movement placed on the carriage as mechanisms for bending the ends of the workpiece, each of which consists of a disk with a pair of bending fingers. The central bending mechanism is made with removable copiers mounted on the punch. The mechanisms of bending the ends of the workpiece are equipped with a support, a puller and a drive for vertical movement of the disk. The mechanism for moving the carriages is made in the form of two independent drives, each of which is connected to one of the carriages. The bending rollers are mounted for installation movement. The support and the puller are oppositely placed in the same horizontal plane, the puller being able to move along the horizontal axis and rotate around the vertical axis

Fig. 1 schematically shows a device for manufacturing reinforcing products, a general view of Figs. 2-4 - flexible ends of the workpiece: in Fig. 5 - s.ema central bending of the workpiece.

A device for manufacturing reinforcing products consists of a housing I, on which a central bending mechanism 2 is located, and a bottom with; mechanisms 3 are flexible ends of the workpiece Mechanisms 3 are flexible ends of the workpiece placed on the carriage. 4 are associated with a movement mechanism, which is designed as a deu. independent drives 5 and moves the carriage 4 along the guides 6. The bending mechanism of the ends of the workpiece each consists of a disk 1 with a pair of bending machines: a finger 8 and is equipped with a drive 9 for turning the disk 7, a drive 10 for the vertical movement of the disk 7, a stripper 11 with a drive J2 and a support thirteen

The mechanism 2 of the central bend is made in the form of a punch 14, interchangeable copiers 15, the bending rollers 16 installed: using the adjusting screw 17, and the drive 18 for longitudinal movement of the bending rollers 16

The drawing also shows the workpiece 19 and the mechanism 20 loading workpieces

The operation of the device is as follows

Before the operation of the device using drives 5, the device is set to

preparation of a certain length In this case, the carriages 4 are moved, respectively, the mechanisms L for bending the youngsters of the workpiece are moved. The workpieces 19 are individually delivered to the bending zone (Fig. 2) and held there

0 support 13 Bending of the workpiece is carried out sequentially First, at the same time, the ends of the workpiece are bent 19 This is done by turning the disks 7 with pairs of flexible fingers 8 around the axis

5, the rotation of the disk (Fig 3) using the drive 9. During bending of the ends of the workpiece, the puller 11 is deflected by the disk 7 around the vertical axis towards the bend, and then after the disk 7 is also returned to its original position

0 returns to its original position and its free end sticks under the bent end of the workpiece 19 (Fig. 4). After that, the disks 7 are vertically moved downward by the drive 10. At this moment, the workpiece

5 19 is held in a horizontal position (Fig. 4) due to the fact that the access point on the strippers 11 and supports + iwatep x 13 If you want to get the product with bends in the same plane, the puller 11 remains in

0 starting position (Fig 4)

If it is necessary to obtain a product with bends in two "planes, the puller 11 is moved horizontally by the drive 12 so that it is free

5 end y: one from under the bent end of the workpiece As a result of this, under the influence of gravity, the workpiece 19 is rolled onto the supports 13 from a horizontal plane to a vertical, stable position

The implementation of the central bending of the workpiece does not depend on what plane the workpiece with the bent ends is in - vertical or horizontal In both of them: in case of operation of the device, in particular, the central bending mechanism occurs identically

Central bending is carried out using bending rollers 16. punch 14

0 and the copier 15 The rollers 16 are driven in motion by the drive 18 and the workpiece 19 is bent according to the configuration of the punch 14 and the copiers 15 The punch 14 and the copiers 15 are interchangeable depending on the shape of the centrifugal bend and the rollers 16 are made adjustable in a horizontal plane with a width of chain attacks under interchangeable punches m copiers.

With the reverse stroke of the rollers 16, the product falls out of the sip of gravity

bending zones After that, the disks 7 are returned to their original position with the help of the drive Yun the cycle of operation of the device is repeated

The use of a retractable disk with fingers, a puller in the inventive device. A replaceable punch with copiers and adjustable bending rollers in width allows expanding the range of products obtained. The use of autonomous drives by the extreme bending mechanism simplifies the device re-adjustment for the corresponding product, eliminates manual labor, increasing mechanization of work.
