Abstract

The invention relates to the processing of metals, pressure.m, in particular, to a die tooling for processing sheet material. The aim of the invention is to expand the technological capabilities of the strain by punching closely spaced holes on mutually perpendicular surfaces of the product. When the slider moves down after punching a hole in the bottom of the product with a vertical punch 2 installed in the slots of the slider 4 located on the top plate, the slider 4 interacts with the wedge mounted on the bottom plate and repositions the vertical punch 2 to move towards the slider movement. This makes room for the passage of the horizon-shaped punch 9, mounted on no / nnnj-ka 8, which is driven by the wedge 3, when punching a hole in the side wall of the product. In this case, it is possible to obtain closely spaced, cored openings in mutually perpendicular surfaces of products on one and the same in one transition. 1 h. and. f-ly, 5 ill.

Description

The invention relates to the processing of metals by pressure, in particular to the stave tooling for the processing of sheet material.
The aim of the invention is to expand the technological capabilities of the Stam by punching closely spaced holes on mutually opposite surfaces of the part.
FIG. 1 shows the heading before starting work, general view; in fig. 2 - the same, in the punching hole of one hole; in fig. 3 - the same at the time of the second hole; pas figs. 4 shows section A-A in FIG. one; in fig. 5 is a section BB in FIG. one.
1It contains an upper plate I, on which vertically rasiolozhenyuyuaneon 2 is installed for punching, wedge 3, along; 1z1ika 4, pressure 5 and bending punches b, and 1p-1zhny plate 7, which is equipped with a slider 8c With a pierced punch 9 for punching, a mantle 10 for punching and bending and a wedge 11.
The vertical punch 2 B1 is nolien with collar 12 and the shank 13, which is located in the hole of the plate 1, and the working horse — in the hole of the clamp 5.
11to.1zu111ka 4 is filled with a groove, located at an angle at its ends 14, made and the fork bite covers the vertical pin 2 2 n shank 13, is installed in the guides 15 and is spring-loaded Hocpe. icTBOM springs 16, screws 17 to plate i8, connected to plate 1 by screw 19.
The clamp 5 is connected to the plate 1 by the guide sockets 20 and is spring loaded with elastic elements 21.
Wedge I 1 has a bevel at an angle sso, less- HIHM angle. A ..
The sleeve 8 is spring loaded with a spring 22, which is equipped with a rod 23. In bending box 6, a groove 24 is made for the passage of a horizontal pin 9.
The stamp works as follows.
The blank 25 is placed in the matrix 10. When the upper plate 1 is exposed to the upper plate 1, the punches 6 bend due to the fact that the bending force is less than the compressive force of the elastic elements 21. After the end of the process, the pressure 5 abuts the matrix 10 and the elements 21 start compress, and the vertical punch 2 punches the hole, while its shoulder 12 rests on the wedge bevel of the slide 4 and, by selecting an angle a less angle, this self-braking connects the vertical pin 2 to the plate 1 through the slider 4.
At the end of the punching stroke 4, and goes to the wedge II, and the wedge 3 finds a lap 1 section 8.

The slider 4 starts moving and moving the punch 2 out of the hole of the die 10, and the slide 8, moving it, produces a punch 9 of the other hole with the horizontal punch 9. At that, due to the withdrawal of the vertical punch 2, the space for the entrance of the horizontal punch 9 is freed.
After lifting the upper plate 1, the uirugi elements 16, 21 and 22 return to the initial position, respectively, the slider 4, the clamp 5 and the slider 8.
To ensure the operation of the pdtamp it is necessary to fulfill the conditions
tgcxK u, and
where | - a slope angle of a groove, in a crawler; 062 — wedge angle of the movement mechanism to the horizontal plane; | .ii - the coefficient of friction between the materials of additional and izolzushki;
1.12 is the coefficient of friction between the materials of the crawler and the wedge of the movement mechanism.
The economic effect of using the invention is provided by the possibility of obtaining closely spaced holes in mutually perpendicular surfaces of products on one stamp in one transition.

Claims (2)

1. A hole punching template containing an upper plate with a wedge mounted on it, an iris. And a vertically arranged punch, and a lower plate with a matrix mounted on it and a slider with a horizontally positioned punch installed with the ability to interact with a wedge, differing By the fact that, in order to expand the technological capabilities of the stamp by punching closely spaced holes on mutually perpendicular surfaces of the part, it is equipped with a mechanism for moving the vertical punch along the axis shtampa.
2. Shtami according to claim 1, characterized in that the mechanism for moving the vertically located punch is made in the form of a spring-loaded slider with an inclined groove installed in the guides on the upper plate, and a wedge mounted on the lower plate with the possibility of interacting with a slider, and This angle of inclination of the groove is greater than the angle of the wedge, the punch is made with a collar in the middle part for placing it by means of the collar in the groove of the crawler, and the tail part in the centering hole of the upper plate.
