Abstract

The invention relates to the processing of metals by pressure, in particular to die tooling for processing sheet material. The purpose of the invention is to improve the quality of parts and reliability of the work of the strains. For this, a single stop of the stamp, made in the form of a slider (P) 1 with notches (B) 7 and a bevel (C) 8 at the working end, is equipped with a pusher 3 with a collar 12. P 1 is equipped with an additional C 10 and an additional B 11. The material is first rests against the surface B 7. At the first working stroke, the pusher 3 retracts P 1. At that, C 8 gets the opportunity to interact with the material, and the pusher 3 stops P I. During further advance, the material acts on C 8 and removes P 1 from the movement zone. In doing so, the P I disengages with the pusher 3. When the material ends, the P 1 returns to the working position. 4 il.

The invention relates to the processing of metals by pressure, in particular to die tooling for the processing of sheet material.

The purpose of the invention is to improve the quality of parts and reliability of the stamp.

FIG. 1 shows the proposed stop, a general view; in fig. 2 - the same, top view; in fig. 3 - slider, isometry; in fig. 4 - part of the pusher, isometric.

Single stop contains slider 1, sub-Single stop to the stamp for processing

spring-loaded 2, and the pusher 3, sheet material, made in the form

spring-loaded 4. The slider 1 slider, installed in one of the slides, is installed in the guide bar 5 of the control strap of the stamp with the possibility of pa and its working end 6 has a notch 7 and. displacement in the direction perpendicular to the p-bevel 8, and the opposite part has a high guide surface of the plank, step 9 with the bevel 10 and the notch 11. On the thickening of its supporting plane the cathele 3 is made a shoulder 12. in the plane of movement of the sheet material, having a notch at the working end

The stop works as follows. Bevel and equipped with a spring, the force of the processed material 13 is fed 20 into the zone between the direction of the stop by its angle into the wall of the notch 7, after which the first working stroke of the stamp is made, during which the upper plate (not shown) moves the pusher 3, which with its flange 12 retracts the slider 1 and stops it, westward into the notch 11. In this position of the slider 1, its bevel 8 is arranged to interact with the material 13, and the notch 7 is recessed into the bar 5. Subsequently advancing

25

In order to improve the quality of the parts and the reliability of the punch, the planes limiting the bevel and the notch and the sliders parallel to the supporting plane are aligned on the slide from the side opposite to its supporting plane and the direction of the spring force, an additional bevel is made facing opposite to the reference plane and following it

on the next step, material 13, I will affect -, - - 1 in the pressure of the base plate the additional „O1. .... „.-

on the bevel 8 of the crawler 1, removes it, freeing it from engaging with the shoulder 12 of the pusher 3, which is raised by the action of the spring 4. In the continuation of all the subsequent work, slider 1 is retracted and abuts against the side edge of the material 13. When material 13 ends, the slider 1 is subject to

the recess and the stop are provided with a pusher mounted for movement in a direction perpendicular to the support plane of the slider, and equipped with a shoulder arranged for engagement with an additional bevel and additional notch of the slider.

FIG. 2

By the spring 2 returns to the working position.

A single stop allows the quality of parts to be improved due to the possibility of using a movable puller and increasing the reliability of work due to the fact that the material moves on the same horizontal level.
