SU403476A1 - STAMP COMBINED ACTION FOR CUTTING - Google Patents

Description

one

This invention relates to the field of pressure treatment of materials, in particular fragile non-metallic materials.

Known stamp combined de1 1 st for cutting and punching of fragile non-metallic materials, containing cutting matrix, punch-matrix, punch punches and spring-loaded ejector and C1).

However, by using them, it is impossible to create a clamping force for high-quality extrusion of fragile non-metallic materials.

In the proposed device, between the top plate and the punches, the base plates are mounted with the wedge P01 nodal points facing each other and the radial wedges radially between them. The latter are described by narrow ends to the sides and are provided with grooves made on the rotary peripheral ends, interacting with vertical wedges, which are mounted in a concentrically positioned base plate of the yoke; In addition, the support plate is connected to the ejector by means of vertical pins arranged parallel to the central axis of the punch.

FIG. 1 shows a sectional stamp, general view; in fig. 2 - upper part of the strain, but not cut.

Combined action stamp between upper plate 1 and punches 2 s

3 mounting plates 4 and 5 with wedge surfaces facing each other with a bevel angle of 13 ° and horizontal wedges 6 radially mounted between them, cut 1, with narrow ends to the ejector 7 and fitted with HJHPOKHx peripheral ends 8 and 8, which cooperate with vertical sleeves 9 with a bevel angle of 15 °, which are installed in the support plates 4 and 5 of the sleeve 10, which is located on the conentric 10. Under the sleeve 10, there is a gasket 11 m, a die-cut matrix 12, inside which an ejector is mounted Tel 7 connected to the lower support plate 5 by means of vertical N1TNFTOV 13 parallel to the central axis npamna. I1TOK 14 with shank 15 passes through the upper tube 1. The stem in the upper shaft is supported by the spring 16.

The vertical ridges 9 are under the action of the springs 17, which are pressed against the threaded plugs 18. At the end of the stem 14 a crosspiece 19 is inserted, which is inserted into the opening of the lower support plate 5.

In the lower part of the strain there is a punch-matrn 20 and a puller 21 connected to the bottom plate 22 of the internal 23, which are external to the children 24.

The strain works as follows.

The billet is placed on the puller 21. The upper part of the stamp is lowered, while the preform is clamped between the die cutter 12, the ejector 7, the puller 21 and the die-mold punch 20. Then the workpiece is stamped, while the ejector 7 remains stationary, and the upper part of the grinder pushes the lower part. .

The pressure of the material being forged is ejected on the pusher 7 through the pins 13 on the plate 5, horizontal wedge 6, to () teaches to move apart, forcibly: i, from vertical wedge 9.

At the same time, according to Clause 1, the checkpoint is co-hg; t; ri.ini - and 5 with wedges 6 and wedges 9 - with wedges ii and the yoke 10 raise the pressure of the ejector required for a good cutting of the part. After the wedge 6 is moved apart to the required distance, the spider 19 with the rod 14 is lifted by the action of the spring 16 and rests against the plate 4.

After the cutting of the 1ntamp is started, it opens, the waste of the workpiece is removed from the junction matrix 20 by the puller 21, and the cutting part remains in the matrix until at the end of the idle stroke the rod 14 of the node is ejected by the ejector press in the slide insert (not shown) does not lower the cross bar 19 in the starting position. The vertical wedges 9 under the action of the springs 17 are lowered and Cli 6 are drawn together. Klii

1i) the support nlit 5 and the ejector 7 are reversed to the initial position, and the part is removed from the Ivanson matrix 20. With the nomination of the threaded nuts 18, the force of the springs 17 is adjusted, and the pressure of the ejector 7 is regulated, which means that the quality of the ejector is up to 10 parts.
