Abstract

STAMP FOR CUTTING THE ROD “VOGO MATERIAL”, containing a base on which a housing is installed with two movable sliders, in which the bushings KNIVES are mounted, as well as a mechanism for moving the sliders, so that the cut of the workpieces, the mechanism for moving the sliders is made in the form of two mounted in the housing with the possibility of moving the drive tappets and two two shoulders with differently sized arms pivotally mounted on the housing, with the larger shoulder of each two shoulders snarling and taken to cooperate with the slide means sootvetstvukshhim spherical bearing.

Description

The invention relates to the processing of metals by pressure, in particular to the use of metal, for cutting bar material.

Known stamp / sh cutting bar material, containing the base, on which is mounted a housing with two movable sliders, in which the sleeve knives are mounted, as well as the mechanism for moving sliders С -Ч

The disadvantage of this stamp is the poor quality of the cut blanks.

The goal of isophene is to improve the quality of the billets.

This goal is achieved by the fact that stamp 15B: for cutting bar material, containing a base on which a housing is mounted with two movable sliders in which the sleeve knives are mounted, as well as a peremetno-slider mechanism, is made in the form of two mounted in the housing with the ability to move the drive pushers and two double-arm levers with different-sized shoulders, articulated 25 on the housing; in this case, the larger shoulder of each two shoulders lever is placed with the possibility of interacting with the co-bolt crescent through a spherical support.

FIG. 1 shows a stamp, a view in section; in fig. 2 is a section A-A in FIG. one.

The stamp contains ocHOBamie 1, on which case 2 is fixed with two paws

mi sliders 3 and 4, in which sleeve knives 5 and 6 are mounted. The mechanism for moving the sliders consists of levers 7 and 8 fixed on axles 9 and 10, pushers 11 and 12 and a vertical wedge 13 spring loaded 14. The contact of levers 7 and 8 with the pushers 11 and 12 through the spherical bearings 15, and with the sliders 3 and 4 through the spherical supports 16.

The stamp works as follows.

A bar of 17 g in the knives is 5 n 6. The press ram presses down (at the moment of greatest speed of movement) with the shank 18 on the high wedge 13. The vertical cain 13, moving down, spreads the pushers 11 and 12, which press on levers 7 and 8. The latter, turning around axes 9 and 10, will mix sliders 3 and 4 towards each other. The knives 5 and 6 cut the workpiece from the sponge 17. To the initial position, the sliders 3 and 4 and the levers 7 and 8 are driven by the action of the springs 19, and the vertical wedge by the action of the springs 14.

Compared with the known arrangement, the use of isoftenia allows low-speed mechanical presses to provide the ability to cut the rods at a single deformation rate, which improves the quality of the cuttable pieces.
