Multifunctional pipe fitting penetrating hole punching device

Abstract

The invention relates to the field of pipe fitting machining, and discloses a multifunctional pipe fitting penetrating hole punching device. The multifunctional pipe fitting penetrating hole punchingdevice comprises a tubular male die support, a male die hole is formed in the male die support, a punch male die is arranged in the male die hole, and the punch male die and the male die support are connected through an elastic piece; and an annular groove is formed in the inner circumferential surface of a punch concave die, a polishing ring is mounted in the annular groove, and a blanking hole aligned with the punch male die is formed in the polishing ring. According to the multifunctional pipe fitting penetrating hole punching device, the male die support and the punch male die are arrangedin a pipe fitting, the punch male die is extruded outwards through an extrusion block, thus burrs in a punched hole are located on the outer surface of the pipe fitting, and later clearing is facilitated; the pipe fitting is secondarily punched through the extrusion block, and thus the burrs are removed; a driving device is arranged to drive the polishing ring to rotate, and thus the outer surface of the pipe fitting is polished; and by arranging the elastic piece, the punch male die can be reset automatically, and the pipe fitting is taken out conveniently.

Description

technical field [0001] The invention relates to the field of pipe fitting processing, in particular to a multifunctional pipe fitting through-hole 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 multi-functional punching device for through-holes of pipe fittings to solve the above problem...
