Multifunction pipe fitting punching device

Abstract

The invention relates to the field of pipe fitting machining and discloses a multifunction pipe fitting punching device. The multifunction pipe fitting punching device comprises a pipe-shaped male diesupport, the male die support is provided with a male die hole, a puncher pin male die is arranged in the male die hole, and the puncher pin male die is connected with the male die support through anelastic piece; a ring-shaped groove is formed in the inner circumferential surface of a puncher pin female die, and a grinding ring is mounted in the ring-shaped groove and provided with a blanking hole aligning to the puncher pin male die. According to the multifunction pipe fitting punching device, the puncher pin male die is extruded outward through an extruding block, so that burrs obtained from punching are located on the outer surface of a pipe fitting, and a later stage of removing is facilitated; the puncher pin male die can automatic reset through the arrangement of the elastic piece, and extraction of the pipe fitting is facilitated; secondary punching is conducted on the pipe fitting through the extruding block, so that the burrs are removed; and the grinding ring is driven torotate through the arrangement of a driving device, so that grinding is conducted on the outer surface of the pipe fitting.

Description

technical field [0001] The invention relates to the field of pipe fitting processing, in particular to a multifunctional pipe fitting punching device. Background technique [0002] The processing of holes on the pipe is mainly mechanical processing, including drilling, milling, etc. In mass production, punching is used instead of drilling and milling, which has the characteristics of high production efficiency and reduced processing costs. At present, for the processing method of punching, when punching ordinary pipe fittings, the commonly used structure is that the punch is outside and the die is inside. If the burr is inward, it is difficult to take out the pipe from the die, and the burr is on the inner wall of the pipe, so it is difficult to remove the burr in the later stage. Contents of the invention [0003] The object of the present invention is to provide a multifunctional pipe punching device to solve the above problems. [0004] In order to achieve the above o...
