A punching device for index loading and unloading

Abstract

An indexing loading and unloading punching device comprises a punching oil cylinder, an oil cylinder connecting plate, a case body, an indexing shaft, a shaft joint, a punching die socket and a punch seat; the punching oil cylinder, the oil cylinder connecting plate and the case body are fixedly connected in sequence; one end of the shaft joint and the end part of an oil cylinder piston rod form indexable connection; the other end of the shaft joint is fixedly connected with the inner side edge of the indexing shaft; the indexing shaft penetrates through an inner hole of the case body; the outer side end of the indexing shaft is fixedly provided with the punch seat; a punch is arranged on the punch seat; the upper part of the case body is fixedly provided with the punching die socket; and a die is arranged on the punching die socket. According to the indexing loading and unloading punching device disclosed by the invention, through a skillfully designed structure of the indexing shaft and related mating parts, indexing is completed by the indexing shaft in a moving process, thereby completing compound functions of indexing, linear motion and punching. Compared with existing punching equipment, the indexing loading and unloading punching device disclosed by the invention is capable of indexing the punch seat by means of power of the punching oil cylinder without increasing a power source to achieve the goal of convenient and fast loading and unloading, and the indexing loading and unloading punching device is not limited by a placement orientation, and is broad in application range.

Description

technical field [0001] The invention relates to a non-standard punching equipment, in particular to an indexing loading and unloading punching device for processing round holes or special-shaped holes of automobile metal parts. Background technique [0002] In the automotive metal parts processing industry, many parts need to be processed with multiple circular holes or special-shaped holes. If the shape of the part is complex and the number of holes to be processed is large, non-standard special punching equipment is usually used to complete the processing. Non-standard special punching equipment requires processing of porous parts, in addition to ensuring its processing accuracy, it must process various holes as efficiently as possible, and requires easy, fast and reliable installation and disassembly of product parts . Figure 10 Shown, is a kind of punching device that adopts at present, and this device drives the movement of slider 16 by the piston rod expansion and co...

Problems solved by technology

In this device, when the piston rod of the oil cylinder is stretched out, the guide rail will tilt downward by gravity to achieve the purpose of convenient loading and unloading, but this device can only rely on gravity to tilt when the device is placed horizontally, and cannot rely on its own power to achieve tilt. When the device cannot be tilted downward when it is not placed horizontally, it will bring convenience to placing and taking product parts, so the use of the device is limited
