Abstract

1. PERENALAZHIVAEMY AND STAMP multianvil for perforating the sheet metal parts with a variable hole pattern comprising a movable part mounted in the die plate, arranged to be axially movable relative to the punch holder punches, punches incorporation node razmescher01y between the plate and the head puller punches and the die installed in the fixed part stamp, characterized in that, in order to reduce the complexity of the changeover of the stamper, it is equipped with a unit for moving off punches in the direction enii matrix. 2. A stamp in accordance with claim 1, characterized in that the node for moving the punches is made in the form of a plate with holes whose axes coincide with the axis of the punches located between the punch holder and the switching on node of the punches with the possibility of interacting with the plugged punches, screws rigidly connected with a puller and installed with the possibility of interaction with the plate, and an elastic element located between the puller and the punch holder.

Description

AI) refers to treating the metals with lanlemii. in particular, to devices for perforation of sheet metal parts with variable pitch of holes.

The closest to the proposed technical essence and the achieved re: (ultatu is a re-adjustable micro-punch stamp for perforation of sheet parts with a variable arrangement of holes, containing fixed. In the MOVEMENT part of the etamplate plate, placed with the possibility of axial movement relative to the punch punch, the node includes a punch, the pansons, the node includes a plate, placed with the possibility of axial displacement relative to the punch pan-pons, the node includes a punch, and the pansons, the node includes a plate with the possibility of axial displacement relative to the punch holder and the punches, the node includes a plate that has axial displacement relative to the punch holder and punches, the node includes a plate that has axial displacement relative to the punch holder and punches, and the node includes a plate with axes that are axially displaced relative to the punchpunch, placed between the plate and the heads of the punches C1.imnik and the matrix installed in the fixed part of the stamp 1.

A disadvantage of the known stamper is the relatively high labor intensity of the retooling of the stamp.

The purpose of the invention is to reduce the labor intensity of the die changeover.

This aim is achieved in that the readjusted multianvil die for punching sheet metal parts with a variable hole pattern comprising ustaiovlennye a movable part schtampa plate arranged to be axially movable relative to the punch holder punches incorporation punch assembly disposed between the plate and the heads of the punches stripper and an array mounted in the fixed part of the belt, equipped with a unit for moving off punches in the direction of the die.

In this case, the movement assembly of the punch is made in the form of a plate with holes, the axes of which coincide with the axis of the punches, located between the punch holder and the switching on station of the punches with the ability to interact with the disabled punches, screws connected with the stripper and installed with the possibility of interaction with the plate and elastic The element is located between the puller and the punch holder.

FIG. I depicts a stamp before the start; technological operation, general view; on

FIG. 2 - the same, after making a technol () giche ": what the operation.

The stamp contains a plate 1, a matrix holder 2 and a die 3 installed in the fixed part of the stamp. In the movable part of the stamp a plate 4 mounted rigidly connected with the shank 5 is mounted. The punches 6 are installed in the punch holder 7 with the possibility of axial re-emersion. The punch insertion unit consists of a template 8 with holes and crackers 9 installed in these holes.

The unit for moving off punches is made in the form of a plate with holes, the axes of which coincide with the axis of the punches 6, screws 11, rigidly connected with the puller 12 and installed with the possibility of interaction with the plate and the elastic element 13 located between the puller 12 and the punch holder 7.

The punches 6 are spring-loaded relative to the puller / springs 14. The material to be processed is indicated with the position 15.

The stamp works as follows.

When lowering the lower part of the punch, the processed material 15 is pressed to the matrix mirror by the puller 12. The force from the upper part of the punch through the crackers 9 re is applied to the punches 6. At the same time, the switched off punches are lifted by the action of the spring 14 together with the plate 10.

When moving the moving part upwards, after performing the tax operation, the screws 11 act on the plate 10, which moves the switched off punches 6 in the direction of the die .;

In the event of a changeover to the new program, template 8 with its 6 holes installed, the crackers 9 are freely removed from the plate 4 and the crackers 9 are installed in accordance with the new program.

Supplying the proposed stamp with a move of off-punches allows reducing the laboriousness of changing a stamp to a new program.
