Abstract

Usage: refers to sheet stamping. SUMMARY OF THE INVENTION: The stamp comprises an upper and lower plate as well as an intermediate yoke plate. On the upper and lower plates are set crush. On both sides of the intermediate cross-plate, containers with an elastic medium are fixed, which have unequal working surface areas. Punches are cut patterns. The intermediate yoke plate is spring loaded relative to the lower plate. 2 ill.

Description

The invention relates to the processing of metals by pressure, in particular to tooling for cold sheet stamping and can be used in mechanical engineering.

A stamp is known comprising an upper and lower plate with two matrices mounted on them with ejectors, guide columns. Between the upper and lower plates, an intermediate traverse plate with two punches fixed on it is installed. However, such a stamp is rather cumbersome and when changing the size of the blanks requires a long laborious readjustment 1.

Known stamp with an elastic medium containing the upper and lower plates, an intermediate plate-traverse, two identical containers with an elastic medium and a hard forming tool 2.

This stamp allows you to stamp two parts in one stroke, yo of the same size. For stamping parts of other thicknesses and sizes, an additional stamp is required, provided with containers with appropriate internal cavity sizes. In connection with this, labor productivity is reduced.

The purpose of the invention is the expansion of the technological capabilities of the stamp by increasing the range of workpieces. The goal is achieved by introducing into the stamp two presses mounted on the upper and lower plates, containers with elastic medium are installed on both sides of the intermediate plate - traverses, a rigid forming tool is made in the form interchangeable cut-out patterns placed between the elastic medium and the pressers, while the intermediate plate - the beam is spring-loaded relative to the lower plate, and the cont Elayers with elastic medium are made with unequal areas of working surfaces.

operating position; in FIG. 2 - along arrow A in FIG. 1.

The stamp contains a bottom plate 1, into which the column 2 is pressed in. A screw 5 is mounted on the bottom plate 1 with a screw 3 and a pin 4. To prevent the workpiece from getting between the container b and the press 5, a stencil is installed 7. The springs 8 are mounted with the possibility of moving along the columns 2 of the intermediate plate-traverse 9, on which containers 6 and 11 with various sizes of working cavities are attached using clamps 10. In the container 6 and 11, gaskets 12 are installed, elastic medium 13, punches 14 in the form of cut-out patterns and blanks 15.

The upper plate 16 is connected to the intermediate plate-traverse 9 using two columns 17. A presser is installed on the upper plate 16, The blank 15 is placed on punches - cut-out patterns 14 into containers 6 and 11 on an elastic medium 13. When lowering the slide of the press associated with the upper plate 16 is the separation of metal, first in the upper container, then g lower, with the same thickness and mechanical properties of the material being cut, because pressure in lower container

due to its large size will be smaller than the top.

Thus, the proposed solution makes it possible to quickly change it to various sizes of parts, which increases the range of machined parts, increases labor productivity, reduces the energy intensity of the stamp.
