Description

The invention relates to the processing of metals by pressure and can be used for the manufacture of core products with thickening at the end.

The purpose of the invention is the expansion of technological capabilities achieved through the installation of an outboard punch in the landing zone with the possibility of reciprocating movement relative to the planted workpiece.

FIG. 1 depicts a principal

circuit machine; in fig. 2basic

the forming part of the automaton; in fig. 3- section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 2; in fig. 5 is a sectional view BB in FIG. 2; in fig. 6 is a cross-section of the FIG. 3; in fig. 7 - types of parts manufactured on the proposed machine.

The machine contains a frame 1 on which the mechanisms for straightening 2, filing 3, cutting 4 of input 5, fixed bearing 6 and movable support 7. are mounted. Supports 6 and 7 are connected by an adjusting screw 8. In support 6, it is mounted on balls 9 by a driving ring matrix holder 10 with matrixes And, and in support 7, an annular matrix holder 12 with matrices 13 is installed. Using an adjusting screw 8, the support 7 is installed in such a position that the annular matrix holder 10 with matrices 11 and the annular matrix holder 12 with matrices 13 are formed with a connector plane some ma first angle 0 ° 30-1 °. This provides free entry of the workpiece in the matrix P and 13, and the removal of finished products from the matrix in the areas of input and removal. In the landing zone of the workpiece, the gap between the clamping dies 11 and 13 is gradually reduced and the workpiece is clamped. With maximum landing force, maximum clamping force is observed.

The machine also contains a positioning unit 14, a tray 15 for removing finished products, racks 16 and 17 with guiding ring-shaped closed grooves 18, in which

Punch holders 19 are mounted, hinged together to form a closed circuit. In the punch holders 19 spring-loaded punches 20 are placed. In the inner zone of the chain, a copy element 21 is rigidly fixed on the uprights 16 and 17. The punch holder 19 has projections 22 on the side of the clamping dies 11 and 13; 23.

The machine works as follows.

The wire is inserted into the straightening mechanism 2 where it is straightened. Then, the feed mechanism 3 is fed to the cutting mechanism 4 and cut it into blanks. The blanks are served in the clamping matrix 11 and 13 by the mechanism 5 input. The driving ring matrix holder 10, rotating around an axis, transfers each matrix with the workpiece from the entry position to the landing position, and then to the finished part removal position.

The ring die holders 10 and 12 and through the protrusions 22 transmit the movement of the plug-holders 19. The protrusions 23 accurately fix the position of the pin holders 19 relative to the matrices 11 and 13.

The required length of the disembarked portion of the workpiece is established by the positioning mechanism 14.

In the disembarking zone, the workpiece is clamped by dies 11 and 13 and landed by a punch 19, which is brought into motion during interaction with the copier element 21. Next, the finished part together with clamping dies And 13 moves to the removal zone, where the dies 11 and 13 are consumed and the part is forced by gravity into tray 15. The punches 20 are returned to their original position by the spring 24.

The proposed automaton provides for the manufacture of parts with various shapes of thickening due to the installation of a heading punch with the possibility of reciprocating movement along the pressure axis.
