Description

one

The invention relates to the processing of metals by pressure.

A known method of manufacturing parts such as glasses with flanges deforms the central part of a cylindrical billet with axial support by its movable punch element and forming a flange from the peripheral zone of the billet.

In order to make it possible to obtain glasses with a conical section, the blank according to the proposed method is precompressed to obtain a stepped glass and compresses it in a stamp onto a cone.

Depending on the materials used, the process can be carried out without heating or with heating the workpiece, or with heating both the workpiece and the tool (heat-resistant and high-strength materials).

FIG. 1 shows the finished part; in fig. 2 shows a pressing process from a stepped glass billet with a thickened edge; in fig. For, b - the process of pressing the pressed glass on a conical punch, the beginning and end, respectively; in fig. 4a, b shows the process of deforming the central part of the workpiece, the beginning and the end, respectively, and the final forming of the flange.

The method is implemented as follows.

From the cylindrical blank 1 in the stamp 2 is pressed by the punch 3 speed glass 4 with

thickened central part 5 and thickened edge 6 (see Fig. 2), the diameter of which corresponds to the diameter of the flange of the finished part.

The resultant semi-finished product is installed in the clamp 7 and crimped last on the punch 8, spring-loaded relative to the crosshead 9 of the press, for example, the upper hydraulic clamp 10 with the force RV.GP. (see Fig. Pros and b). Having finished compressing the semifinished product along the conical punch, they begin to deform the piercing punch AND the central thickened part 5 with its simultaneous back-up from the bottom with the movable element of the stamp 12 with the PCT force, which is accepted less than the deformation force (see Fig. 4a).

The process is completed by forming a cylindrical part 13 of the part and the bottom 14 of the required thickness from the central part of the semi-finished product. At the final moment the mobile yoke 9 compresses the hydraulic clamp 10, touches the stops 15 located on the conical punch, and deforms the press P from the thick edge of the semi-finished product flange 16 parts.
