Abstract

The invention relates to the processing of metals by pressure and can be used for the delivery of single-length round billets to the treatment area. The purpose of the invention is to increase the reliability of the issuance of blanks that have a curvature. The delivery of the blanks is carried out from the storage bin, in which two pairs of vertical guide lugs are placed. At the entrance of the levers to the area of the bunker, the bushing of the shutter opens the bunker. The next billet leaves the storage bin and falls into the slots of the levers, resting on the limiting protrusion of the cutter body. The lever groove is bounded by a pusher and a spring loaded sponge. The bottom of the groove is located below the level of the stop. When removing the workpiece from the zone of the hopper, the pusher removes the workpiece from the limiting protrusion. It sinks to the bottom of the groove. At the same time, the spring-loaded bushing of the shutter overlaps the bunker, holding the remaining blanks. For a more reliable entry of the workpiece into the grooves of the delivery levers, sprinkler springs are installed on the front wall of the bunker. 1 hp f-ly, 5 ill.

Description

one

The invention relates to the processing of metals by pressure and can be used for the delivery of long pieces from the bunker to the treatment zone.

The aim of the invention is to improve the reliability of the issuance of blanks having a curvature.

FIG. 1 shows a bunker; in fig. 2 - the same, top view; in fig. 3 - bunker at the time of height, section; in fig. 4 - levers at the moment of transfer of the workpiece to the working ZONE; in fig. 5 is a diagram of the arrangement of the workpiece between the projections.

The storage bin consists of vertical walls 1 and 2, on which two pairs of vertical guides 3 and 4 are wide opposite each other, where d is the diameter of the workpiece. The distance B between them is determined depending on the curvature of the workpiece and can be determined as follows (Fig. 5):

B d + ctga.d + 2dtga d (+ 2tga), where a is the angle of curvature of the workpiece.

In other places, the distance between the walls of the bunker may be (2-3) d, in these places there are notches 5 on the walls of the bunker.

Thus, the hopper loading slot 6 has a variable width from B to (2-3) d.

The workpiece cutter consists of the housing 7 and the spring-loaded sleeve 8. Two cases 7 of the workpiece shut-off devices are attached to the wall of the bunker I. The housing 7 has a limiting protrusion 9 located under the slot 6 of the hopper. The upper platform 10 of the protrusion 9 is located from the lower end 11 of the bunker

at the calculated distance and forms with it a discharge gap.

To transfer the workpiece 12 from the hopper to the working area, there are two levers 13 having a groove 14 under the workpiece 12 formed by a pusher 15 and a spring-loaded sponge 16. The depth of the groove 14 exceeds the diameter d of the workpiece 12. A spring-spreader is attached to the wall 2 of the hopper.

The device works as follows.

The blanks 12 are placed in the loading slot 6 of the bunker, and despite the curvature reaching (2-3) d in any plane, they pass between the walls, touching them only in the zone of the vertical projections 3 and 4, and the lower 2-3 The arms generally leave the walls of the hopper and are opposite the notches 5. At the moment when the levers 13 are outside the hopper, the spring-loaded sleeve 8, which is in the right position (not shown), prevents the workpiece from falling out.

When the levers 13 come to the zone of the (extraction) height of the workpiece, the sleeve 8 is pressed to the left, the sponge 16, abutting against the wall 1, is pressed to the right, and the next workpiece 12 falls on the bottom surface of the platform 10 of the cutter 7. And in view of the fact that the groove 14 in the levers

13 is made deeper, the base blank 12 does not touch it.

At the moment when the levers 13 begin to move into the working area, the workpiece 12 is pushed by the lever 13, comes down from the body 7 of the shutter, lowers to the bottom of the groove

14 lever 13 and is held there between the folding sponge 16 and the pusher 15, and to guarantee this lowering

nor serve as springs, sending the workpiece to the bottom of the groove 14 of the lever 13.
