Abstract

The invention relates to the processing of metals by pressure, in particular, to dies for bending sheet blanks. The purpose of the invention is the expansion of technological capabilities by providing bending with different angles of inclination of the middle part of the product to its shelves. The stamp contains a composite matrix (M) and a punch (P), an adjustable stop and the mechanisms for adjusting parts of the matrix and the punch. Parts M and P are made to move in mutually perpendicular directions and have working surfaces inclined towards the punch axis and equally directed. The stamp is tuned to a particular product by moving similar parts M and P vertically and horizontally. Execution of M and P similar with the possibility of similar movements of their parts increases the versatility of the stamp. 8 il.

Description

The invention relates to the processing of metals by pressure, in particular to dies for bending sheet blanks.

The purpose of the invention is the expansion of technological capabilities by providing the possibility of bending with different angles of inclination of the middle part of the product to its shelves.

FIG. 1 shows a stamp, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 1, FIG. 4-8 — bending circuits.

The stamp contains a composite punch And the matrix, an adjustable stop and the mechanisms for adjusting the parts of the punch and die. The punch and die are made similar, so the description applies to both the punch and the die. In the holder 1 in the horizontal j guides, a part 2 is installed

the possibility of moving horizontally from the screw 3, freely rotating in the casing 1. In the vertical guides of the casing 1, part 4 is disposed with the possibility of vertical movement from the wedge 5; located under the working part 4 and the screw 6 freely rotating in the holder. The spring 7 is installed in the window of part 4, interacts with the stop 8, fixed in the holder. The working surfaces of the parts of the punch and die are inclined to the axis of the punch and equally directed.

Before the flexible die is adjusted to a specific product, calculating the necessary movements of the parts of the punch and die. The adjustment can be carried out in several ways: one part of the punch is lowered, and

a similar portion of the matrix rises; similar parts of the punch and die are raised (or lowered), with the plug or die being rotated 180, and then the vertically movable parts must interact with the parts moved horizontally.

Making the punch and die similar, with the possibility of similar movements of their parts with inclined working surfaces, increases the versatility of the punch.
