Description

The invention relates to the processing of metals by pressure, and more specifically to devices providing for the processing of strip and sheet material in the working zone of the stamp.

The aim of the invention is to reduce the dimensions of the stamp.

FIG. 1 shows a stamp for trimming the side edges; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a diagram of the mutual arrangement of the wedge and wedge support in the process of interaction.

The stamp contains the stop 1. located on the bottom plate 2 of the stamp materials (sheets) 3, the upper cutting section 4, located on the top plate 5 of the stamp. In the stamp there is a movable rammer 6 for moving material 3 mounted in a stroke compensator, which is made in the form of a holder 7, in the cavity of which a spring 8 is placed, interacting with the rammer 6. The stroke compensator is located on the movable carriage 9 placed on the housing 10 fixed on bottom plate 2 stamp. In the carriage 9, a stop pin 11 is fixed in contact with the springs 12 and 13 located in the housing 10. A spring 12 is inserted into the structure to return the carriage to its original position. The wedge 14 is made with a protrusion 15 that performs the functions of a copier. The wedge 14 is rigidly fixed in the top plate 5 of the stamp and has the form of a plate with a protrusion 15 located in its lower part, having a tilt angle towards the movement of the carriage 9 and cooperating with the wedge support 16, located in the form of a protrusion on the lateral surface of the carriage 9. Protrusion

15 has a pair of working faces, made with a bevel at equal angles and located on opposite sides of the protrusion. The interaction of the protrusion 15C wedge support 16 provides movement of the carriage 9 with dosylaglek 6 in the direction of the material 3 and the movement of the material 3 to the fixed stop 1.

In this konfuktsm occurred moving the wedge and the upper version and, as it were, run-in around the mill 16.

The sheet material is laid on the bottom plate 2 of the stamp. At the same time, the upper plate 5 of the stamp with the upper cutting section 4 and the wedge 14 is located in the uppermost position. When lowering the top plate 5 of the stamp, the wedge 14 with the surface a of the protrusion 15 interacts with the wedge support 16 of the carriage 9, while the carriage 9 together with the dispenser 6 moves from the initial position to the left, the dispenser 6 from the position r to the position in compresses the spring 13 with a persistent pin 11. At the same time, the expander 6 moves sheet 3 until it stops 1.

Upon further lowering of the wedge 14, the carriage 9 stops in the leftmost position, while the rammer 6 occupies position c. Then the carriage 9 moves under the action of the spring 13 from the leftmost position to the initial position, the rammer S from position to moves to position r, allowing the cut-off section 4 to pass past the floor 6 to cut the edge of the sheet 3.

Upon further lowering of the wedge 14, the collector 6 of the carriage 9 remains stationary in the position r, since the wedge is

16 comes out of the interaction with the protrusion 15 of the wedge 14.

During the course of the wedge 14 upward surface b of the protrusion 15 interact with the wedge

5 with the support 16 of the carriage 9, moves the carriage 9 to the right from the initial position to the extreme right, compressing the spring 12 by means of a pin 11, while the discharger 6 will move from position r to position d and

10 the carriage 9 moves under the action of the spring 12 to the left from the extreme right position to the initial position, while the scroller 6 moves from the position to the position g. The initial position of the carriage 9
