SU1731389A1 - Radial stamping device - Google Patents

Abstract

The invention relates to the processing of metals by pressure and can be used for the radial forming of ribbed products mainly from light alloys. The purpose of the invention is the expansion of technological capabilities through the production of ribbed products with different tops of the edges. The device consists of a set of basic and additional punches. Between the main punches are installed elastic elements with additional punches fixed on them. At the time of the working stroke, the main punches, moving closer together, interact with their elastic elements with their side surfaces. In this case, additional punches are introduced into the tops of the formed edges. The invention allows the product range to be expanded. 6 Il.

The invention relates to the processing of metals by pressure, in particular, to devices for stamping ribbed articles mainly from light alloys.

The aim of the invention is the expansion of technological capabilities by ensuring the production of ribbed products with different shape of the tops of the ribs.

Figure 1 shows the device in the initial position; figure 2 - section aa in figure 1; on fig.Z - view B in figure 1; 4 shows the device at the final moment of punching; in fig. 5 shows a section B-B in FIG. four; FIG. 6 is a view of FIG. four.

The device for radial stamping comprises punches 1 mounted in the holder 2 with the possibility of radial movement. The inner surface of the cage is made inclined respectively mating support surface of each punch. The lateral surfaces of the punches are made with transverse grooves 3 with elastic elements 4 placed in them. Each elastic element is installed with the possibility of interaction with the lateral surfaces of adjacent punches. The respective resilient elements are fixed by means of connecting rods 5 to bases 6 with additional punches 7 mounted on them. The punches 1 are displaced in the radial direction by means of rods 8 and 9 of power cylinders 10.

The device works as follows.

In the initial position, the billet 11 of light alloy is installed between the punches 1. When making a working stroke, the punches interact with their supporting surfaces with an inclined surface.

the cage moves in the radial direction, affecting the workpiece. The billet metal, deformed, flows into the space between the punches 1, where additional punches 7 are installed. In this case, longitudinal edges are successively formed on the workpiece due to the radial movement of the punches 1 and their tops due to the impact of additional punches 7. the stroke located in the grooves of the punches elastic elements are compressed, thereby tracking the change in the distance between the punches I. During the reverse course, the elastic elements expand as the distance between the punches increases and 1, during the entire working cycle, functions as a tool holder for additional punches 7. At the end of the working cycle, the workpiece is moved in the axial direction for subsequent crimping. The number of basic and additional punches, as well as elastic elements, is determined by technological necessity. Device can be used

when receiving ribbed products with various configuration of tops of edges.
