Abstract

The invention relates to the processing of metals by pressure, in particular to a tooling for punching holes in the walls of hollow articles. The purpose of the invention is the expansion of technological capabilities by obtaining products with grooves located at opposite ends. At the working position of the stamp are located (M) 1 and punches (P) 9. M 1 is fixed on the upper movable plate 2, P 9 is fixed on sliders 7 and 8, which move along the lower fixed plate 5 perpendicular to the pressure axis of the stamp. The blanks 12 are moved to the working position in the drive tray. The wall of the blank rests on the inclined end of the stop. Plate 12, M 1 and wedge 4 are lowered. The wedge 4 moves the sliders 7 and 8 and P 9 in the direction of the pressure axis. P 9 enter the cavity of the workpiece. With further lowering of the M 1 when interacting with P 9 punches the grooves at both ends of the product. 1 hp f-ly, 5 ill.

Description

The invention relates to the processing of metals by pressure, in particular to a tooling for punching holes in the walls of hollow articles,

The purpose of the invention is the expansion of technological capabilities by obtaining products with grooves located at opposite ends.

FIG. 1 shows a stamp in its highest position; in fig. 2 - the same, in the lowest position; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - finished product; in fig. 5 is a section BB in FIG. four.

The stamp contains a matrix 1 connected to the upper plate 2 by means of a piercer holder 3, in which are fixed

wedges 4; On the lower fixed plate 5, guides 6 are installed, having rectangular-shaped grooves, in which slider 7 and 8 are mounted with reciprocating motion along the longitudinal axis. Sliders are made with oval projections serving as punches 9 for punching holes. For final fixation of the products during punching, pads 10 of slides 7 and 8 serve. Sliders 7 and 8 have internal inclined grooves 11, the surfaces of which interact with the surfaces of the wedges 4. To feed the workpieces 12 into the working area, the stamp is provided with an inclined tray drive 13 having cross section

N5

the shape of the rectangle along which the workpiece rolls and locks between the edge of the tray and the spring-loaded stop 14 with an inclined plane 15. The gap between the stop 14 and the edge of the storage tray 13 is larger than the diameter of the product being made and the stop is equipped with a screw 16 for adjusting it. 5 has a window 17 for removing finished products and detours. The stop 14 is spring loaded 19.

The stamp works as follows.

With the upper position of the matrix 1 (Fig. 1), the workpiece rolls freely along the inclined tray 13 and locks between the edge of the tray 18 and the plane 15 of the stop 14, which is pressed by the spring 19, Polishers 7 and 8 are in the extreme position (Fig. 2). During the downward motion, the inclined plane of the wedges 4 interacts with the inclined planes of the sliders 7 and 8, setting the latter to the working position. In this case, the punches 9 are included in the blank 19, and the planes 10 of the sliders 7 and 8 finally fix the blank 12 along its longitudinal axis.

With further progress, the matrix enters the punches, punching the grooves, simultaneously pushes the processed product and it, acting on the inclined plane 15 of the stop 14, pushes the last one, giving the opportunity to remove the product down through the window 17 in the lower plate of the stamp.

During the progress of the slide A of the press upward, the matrix leaves the interaction with the punches and the latter are moved apart under the action of wedges.

The stamp is ready for the next operation.
