Description

2. The device according to claim 1, 1 and 2, with the fact that an additional support for replan is installed on the frame; in fig. figure 1; in fig with the bottom; on figo

The invention relates to the field of metal forming, in particular, to devices for molding molding hooks.

The aim of the invention is to increase the productivity and quality of perpetual hooks.

FIG. 1 shows a device, a general view; figure 2 - the same view in

3 - section AA on; 4 - bending mech- 5. - section BB in FIG. 4; in fig. 5 - diagram of the operation of the bending mechanism.

 The device) for flexible molding hooks consists of straightening mechanism 2, feed mechanism 3, bending A and cut-off 5 mechanisms installed on the base 1. The feed mechanism includes a fixed 6 and a movable 7 gears, a worm to 8, which is made touched for both gears. On the gearbox 6, the guides 9 are fixed, in which the housing 10 of the movable gearbox 7 is mounted. On the guides 9 there is a yoke 11, bearing the support. 12 screw 8 and screw 13, kinematically connected to the housing 10 of the movable gearbox 7. Feed rollers 16 are seated on the axles 14 of the worm gears 15.

Bending mechanism. 4 made in. as a bending mandrel 7 with a forming surface 18 at the end of the bending punch 19, made in the form of a single-arm drive lever mounted on the frame with a groove 20 on the working surface forming a 3-gauge caliber 21 with a forming surface. The bending punch 19 is kinematically connected by the lever 22 to the cylinder 23 and has an additional forming surface 24 at the end. In addition to

the wire feed magnitude associated with the bend-drive lever.

Moreover, on the base 1 a roller stop 25 and a box 26 for finished hooks are mounted. The device has a control panel 27, an abutment 28 for limiting wire travel.

The device works as follows.

. The wire 29 is threaded into the mechanism 2 straightening and the feed rollers 16, clamping with the screw 13, and the wire 29 is fed to the middle of the bending punch 19. The cylinder 23 is turned on and the bending punch 19 is turned by means of the lever 22, the bending end of the wire in the caliber 21 is bent formed by the forming surface of the bending mandrel 17 and the forming groove 20 of the bending punch 19, after which the bending punch 19 is returned to its original position. The wire is then fed from the contact of its curved end with the stop 28, the mechanism for turning the punch 19 is turned on, which initially deforms the wire in the newly formed caliber 21 and simultaneously bends the free end of the wire from the stop 28 to the roller stop 25 (FIG. 6). Upon further rotation of the punch 19, the wire fits its forming end and, with the help of the roller 25, bends another wire.

When the end position of the bending punch 19 is reached, the wire enters between the knives of the cutting mechanism 5, which cuts the wire into E-shaped hooks falling into the duct 26. The punch 19 returns to its original position, and the wire 29 with the remaining bent end moves to the stop 28 and the cycle repeats.

Claims (2)

DEVICE FOR FLEXIBLE FORMING HOOKS, including wire feed, straightening, cutting and bed-mounted mechanisms for bending wire, comprising a bending punch, a bending mandrel and a bending roller stop, characterized in that, in order to increase the productivity and quality of the forming hooks, the bending punch made in the form of a single-arm drive lever mounted on a bed with a groove on the working surface, forming a closed gauge with the forming surface of the bending mandrel, and an additional forming surface n end thereof for interacting with the bending roller stop, the cutting mechanism is disposed between the bending mandrel and the bending roller stop, and the lever at the position of the cutting mechanism has a recess to cover said mechanism. 2. The device according to π. 1, the result is that the feed rate is controlled by the fact that on the bed frame the docks are connected with the bending drive. The stop for the lever has been fully installed.
