Abstract

Form block for sheet stamping with an elastic medium containing a punch with a working part made in the form of a part, a fixed clamping support, characterized in that the fixed clamping support is mounted on the punch on two guide pins with the ability to move when changing equidistant working part of the punch and is equipped with a replaceable gasket, located between the punch and the fixed clamping support.

Description

FORM BLOCK FOR STAMPING ELASTIC

Formblock refers to stamping dies and can be used in the manufacture of spatial sheet parts in the aviation, automotive and other industries.

There is a known form block containing a punch and a fixed clamping support fixed on a common base (1). When stamping with an elastic medium, the fixed clamping support provides prevention of the loss of stability of the formed side of the workpiece by giving it a spatial shape.

A disadvantage of the known form block is the complexity of the development of the technological process due to the lack of the ability to adjust the gap between the punch and the stationary clamping support without its refinement. With a large gap between the punch and the fixed support, corrugation of the formed side occurs, with a small gap - rupture or under-stamping of the side.

WEDNESDAY

in addition, in a known design, the height of the mold block increases compared with the working part by the thickness of the base. Therefore, for large-sized parts with a large curvature of the wall, the form blocks will turn out to be very high, which often limits the use of existing equipment for stamping with an elastic medium.

The purpose of creating a utility model is to simplify the development of the process by providing the ability to adjust the gap between the punch and the fixed support during readjustment and reducing the height of the form block.

The goal is achieved by installing a fixed support on the punch on 2 guide pins with the ability to move when changing equidistant working part of the punch and providing the mold block with a replaceable gasket located between the punch and the fixed clamping support.

Due to the lack of a common base, the height of the form block is minimal.

In FIG. 1 shows a general view of the form block;

in Fig.2 is a top view;

in Fig.Z - section along aa.

The form block contains a punch 1, a fixed clamping support 2, a replaceable gasket 3. The clamping support is mounted on the punch on 2 guide pins with the ability to move when changing the gasket 3 is equidistant to the working part of the punch. Guide pins

provide accurate fixation of the fixed clamping support relative to the punch during stamping, and due to the absence of a common base, the height of the mold block is minimal. To fix the workpiece 5 are the pins 6.

The form block is installed on a press for stamping with an elastic medium and works as follows; in this way.

The workpiece is placed on the form block and fixed with 2 pins 6. When exposed to an elastic medium, stamping-drawing the bead into the gap between the punch and the fixed support. After the end of the working stroke, the part is removed from the form block. The required thickness; the inu of the replacement gasket 3 is specified according to the results of trial stamping. If the stamping is not stamped, a lining of a larger thickness is installed; others, in the presence of corrugation in the side zone, a lining of a smaller thickness is installed: the others.
