Description

The invention relates to the field of metal forming and can be used to feed strip and strip material into the treatment area.

FIG. 1 shows a device for feeding a strip and band material into a treatment zone; in fig. 2 shows section A-A in FIG. one.

The device contains a drive shaft 2 installed in the bearings of the housing 1, carrying two projectiles similar to (3) and 4, a falling carriage 5 and a parallelogram mechanism 6 connecting the falling carriage 5 to the frame 1. The cam 4 is made quick-change: it is seated on the shaft along a conical fit and tightened by a nut 7. In the feeding carriage 5 there is a horizontal groove in which the cam 3 of the smaller working profile and horizontal prismatic guides are inserted, on which the wedge 8 is permutable and secured by means of a wedge 8 Lanks 9, forming a vertical groove of adjustable width for the working profile of the cam 4.

In the β-feeding carriage 5, bushings 10 are fixed, along which the columns 11 move, carrying at one of the ends of the spring .12, and at the other end the clamping jaw 14 fastened with nuts 13 and having rollers 15 at the ends. The latter are in contact with the clamping jaws 16 in the form of levers mounted on the housing 1 using axes 17 symmetrically with respect to the feed axis. Position 18 marked feed material.

The device works as follows.

The cams 3 and 4 are driven in rotation from the shaft 2 and the feeding carriage 5 is driven in motion along the path of the rectangle. In this case the movement

on the side vertical sides, a smaller cam 3 is provided, and a displaceable cam 4 moves on horizontal bases. The material 18 is moved by the clamping sponge 14 and the body of the feeding carriage 5. When the material 18 is released, the clamping jaws 15 turn the rollers 15, which press the material 18 to the body 1. The pantograph supports the plane-parallel motion of the feeding carriage 5. The feed pitch accuracy depends on the state of the mating of the laminated cam 4 with the bars 9. The resultant nose gap between them is eliminated by moving the splines 9 to full contact with the cam.

The effect of using the device is to maintain the high accuracy of the feed pitch, and

 also in the possibility of quick readjustment to the next largest feeding step.
