RU1803246C - Horizontal forging machine die - Google Patents

Abstract

Usage: metal forming, in particular the production of forgings on horizontal forging machines from piece blanks. SUMMARY OF THE INVENTION: a stamp comprises a punch mounted on a slider, movable and fixed blocks of half-matrixes with half-matrixes installed in them. To fix the workpiece in a stream without using tongs, half-holes are made with an inclined plane of the connector. In this case, the stationary semi-matrix is deployed around the axis of the brook with its lower edge under the line of action of the center of gravity of the workpiece. 1 s.p. f-ly, 4 ill.

Description

The invention relates to the processing of metals by pressure, in particular to dies for a horizontal forging machine for producing forgings such as rods with a head.

The purpose of the invention is to simplify the design of the stamp.

The goal is achieved in that in the known die to a horizontal forging machine, as a means for fixing the workpieces, a directly stationary half-matrix made with an inclined plane of a connector with a moving half-matrix is used. In this case, the movable half-matrix is made with a camber angle of the upper edge of the handle equal to or exceeding the angle of inclination of the half-matrix connector plane by 0-8 °.

Thus, a stamp with an inclined half-matrix connector makes it possible to position the workpiece in the semi-matrix connector without using any special means to support it. When the stamp is opened, the workpiece does not fall.

In FIG. 1 shows a stamp in a working position, general view: in FIG. 2 - fixed inclined matrix from the side of the punch; in FIG. 3 is a section BB in FIG. 1; in FIG. 4 - section BB of the half-matrix in the open position with the workpiece on the fixed part of the half-matrix.

The stamp for the horizontal forging machine contains a punch 1 fixed on a slider (Fig. 1), movable 2, fixed 3 (Fig. 3, 4) blocks with half-matrices 4 and fixed 5 mounted respectively, with the connector tilted towards the fixed block in clamping part brook. The angle of the half matrix 10-20 °,

The lower edge of the clamping part, the handle of the fixed semi-matrix on which the workpiece is located, is sharp, while the other edges in the clamping part of the handle are made with a camber angle, and the upper edge of the movable semi-matrix is made with a camber angle D of a large angle a from 0-8 °.

ON

The depth of countersink under the head of the fastening bolt 6 (Fig. 4) for the half-matrices rotated at an angle a determines the location of the fastening plane, is made different in half-matrices with an inclined connector and is interconnected with the angle of inclination. The half-matrix bolt plane lies in the same plane as the half-matrix block mount plane.

The stamp works as follows. The punch 1 is retracted, the half-matrix 4 and 5 are opened, the heated workpiece 7 is placed on the lower edge of the stationary half-matrix 5.

The blank lies on a ledge in a half-matrix without additional support with ticks. During the working stroke, the half-matrix closes, the punch deforms the workpiece.

After the punch returns to its initial position, the half-matrix opens, the workpiece remains on the inclined stationary half-matrix, from where it is removed or transferred to the next stream.

The design of the stamp eliminates the use of special means to support the workpiece when closing the stamp, deforming the workpiece and opening the stamp.

This provides simplification of the stamp, convenience and safety in the work of the puncher. Formula A
