Description

one

The invention relates to a device for the treatment of metals by pressure, in particular to devices for the manufacture of rolled sleeves of a tape material.

An automatic device for manufacturing rolled sleeves of a tape material is known, comprising a nodachi mechanism, pieces of the workpiece in width and length, a sleeve forming unit on a mandrel, and a calibration unit with a stepped punch rigidly fixed in the housing of the device and connected to the drive of the reciprocating movement cylindrical shape 1.

However, this device is not productive enough.

The aim of the invention is to improve the performance of the device.

For this purpose, the formation and calibration units are positioned successively in the direction of material supply, the mandrel of the formation unit is installed with the possibility of reciprocating in the direction perpendicular to the direction of its axis parallel to the direction of material supply, and the device body is equipped with an inclined chute fixed between the nodes of formation and calibration.

The invention is illustrated in the drawings, where in FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 - section A-A of FIG. one; in fig. 3 - section bb FIG. one; in fig. 4 shows a section bb of FIG. one; in fig. 5 shows a section of GGD FIG. one; in fig. 6 is a section of DD-D. one.

On the upper movable plate 1 of the device there are successively installed a punching punch 2, a stepping knife 3 of the assembly, sections of the workpiece are cut, remote spacers 4 and 5, a notch punch 6, nodes of sections of the preparations along the length, bending matrices 7 and 8, a movable semi-matrix 9 of the node

forming the sleeve and calibrating the puapson Yu, having a cylindrical stepped shape.

A bracket 11 is also fixed on the plate 1, and the plate itself is attached to the press slide by a shank 12.

In the case 13 of the fixed bottom plate of the device, the matrix 14-17, the limiter 18, the spacer 19, on which the clamp 20 is fixed, the punches 21 and 22, the spring-loaded mandrel 23 with the forming punch 24 placed on it, the fixed semi-matrix 25, the inclined feed chute 26 sleeves 27 from the formation position to the calibration position and the calibration matrix 26. The axis of the mandrel 23 is parallel to the material feed direction. In the case 13 of the assembly there is also a mechanism 29 for cleaning the tape material 30 and the case 31, in which the feed rollers 32 and 33 are equipped with levers 34 having a protrusion 35 at the end.

When the press ram goes along with the plate 1, the bracket 11 also moves together with the plate, making part of this stroke freely, up to the protrusion 35 of the lever 34. Continuing down, the bracket 11 with its upper edge rotates the lever 34 over the protrusion 35 relative to the axis of the roller 33, which Rotating, rotates the roller 32 connected to it by a gear (not shown), and both rollers, acting on the strip previously cleared in mechanism 29, move it to the treatment area up to the stop (not shown). Upon further downward movement of the plate 1, the rollers 32 and 33 are rotated relative to the strip, and the tools mounted on the upper plate 1 punch the hole with the punch 2, trim the strip laterally along the sleeve with a stepping knife 3, cut the strip in a direction perpendicular to its longitudinal axis, punch 6, pre-bending of the ends of the strip with matrix 7, bending in the shape of an oval with matrix 8 and molding the sleeve on the punch 24 with movable 9 and fixed 25 matrices.

When the plate 1 moves upwards, the mandrel 23 is released from the action of the movable half-matrix 9, and due to the spring rises up. At the next course of the plate 1 down, the strip 30, fed by the rollers 32 and 33, pushes the formed sleeve 27 from the punch 24 mounted on the mandrel 23 to 26. And since the calibrating punch 10 at this moment takes the lower position, the caliber of the previous sleeve, and access in the matrix 28 is blocked, then it holds the sleeve 27 in the groove 26 with its upper step. During the next course of the plate 1

up the calibrating punch 10, lifting, makes room for the next sleeve, which rolls along the chute 26 into the hole of the die 28. With the punch 10 going down, this sleeve is calibrated and pushed into the drive (not shown). a smooth core of the punch 10 in the chute 26. The cycle is repeated.
