Vertical type rotary opening and closing device for rotary die position of numerical control turret punch press

Abstract

The invention discloses a vertical type rotary opening and closing device for rotary die position of numerical control turret punch press, which comprises an upper rotation disc, wherein an upper die sleeve is mounted in the upper rotation disc; a step is arranged at the lower part of the upper die sleeve; the outer circumference of the step of the upper die sleeve is connected with the upper rotation disc in a matching manner; a groove is formed in the upper rotation disc; a pin shaft is mounted in the groove; a guide sleeve is mounted and positioned at the lower part of the upper rotation disc and on the outer circumferential surface of the upper die sleeve; a plurality of penetrating holes uniformly distributed in the circumference surface of the guide sleeve; a circular arc groove is formed in the bottom of one of the penetrating holes; a guide rod penetrates through one of the penetrating holes; the guide rod is butted with the pin shaft; an semi-circle arc groove matched with the circular arc groove is formed in the lower part of the upper die sleeve; an air cylinder is fixedly mounted and positioned at the upper part of the upper die sleeve through a fastening piece; a jacking rod head is mounted at the piston rod head part of the air cylinder; the jacking rod head is butted with the guide rod. The protruding and retraction of the jacking rod head at the piston rod head part are controlled by the air cylinder, so that the position of the pin shaft is controlled though the guide rod, rotary opening and closing of the upper rotation disc can be realized; the device is flexile and reliable for use and is high in working efficiency.

Description

technical field [0001] The invention relates to the technical field of mold devices, in particular to a vertical rotary opening and closing device for a rotary mold position of a CNC turret punch press. Background technique [0002] The mechanical CNC turret punch press adopts Siemens CNC system and automatic programming software. It is widely used in the plate processing of electrical cabinets, electrical cabinets, instruments and meters, hardware appliances, spinning and dyeing machinery, elevator decoration, marine air conditioners and other industries. It has a rotating die position, through the rotation of the rotating die position in the circumferential direction, different angles are changed, so as to change the direction of the die and punch out workpieces with different shapes and complex shapes. [0003] In the rotary die station of the prior art, the rotating disk of the rotary die station rotates under the action of the power transmission mechanism. When changin...

AI Technical Summary

Problems solved by technology

[0003] In the rotary die station of the prior art, the rotating disk of the rotary die station rotates under the action of the power transmission mechanism. When changing the angle, it is necessary to change different punching dies. At this time, an intermittent stop is required to allow the required dies to In place, and then punch the workpiece, the rotary die in the prior art cannot be stopped intermittently, and the rotation speed can only be reduced by the power transmission mechanism. Free rotation occurs below, and its work is unreliable. When changing the mold, there are potential safety hazards. If the mold is not installed properly, it is easy to cause damage to the mold, shorten the service life of the mold, and reduce production efficiency.
