Pipe bending and ring sleeving integrated machine for pipe fitting

Abstract

A pipe bending and ring sleeving integrated machine for a pipe fitting comprises a pipe cutting part, a bending part, a discharging part and a ring sleeving mechanism which are sequentially arranged,wherein the pipe cutting part is used for cutting the pipe fitting into pipes with specified length; the cut pipes are fed into the bending part for bending; the pipes are bent into U shapes and thenare discharged to the ring sleeving mechanism for sleeving with rings through the discharging part. With the adoption of the machine, the U-shaped pipe bending and ring sleeving processes can be finished by one machine, so that the carrying ring is reduced, the production efficiency is high, and the occupied area is small; a mode of rotatably cutting without scraps through an inner cutting tool iscarried out, so that cutting scraps cannot be produced; a bent U-shaped elbow workpiece can be directly degreased without being washed, thus zero emission of washing liquid is realized, and the environmental protection is realized; and moreover, the workpiece is uniformly stressed during being cut, and an inclined notch is avoided; a following part is additionally arranged during bending, so thatthe abrasion of the outer sidewall of a metal pipe fitting is decreased, and the quality of the bent metal pipe fitting can be effectively improved.

Description

technical field [0001] The invention relates to an integrated machine for pipe bending and collars. Background technique [0002] The existing pipe bends and collars are completed by the pipe bender and the collar machine respectively, and after the pipe bender is formed into a small elbow, it needs to be deburred, cleaned and dried by a cleaning machine before it can pass through the collar machine. The welding ring is sleeved on the U-shaped elbow, so three pieces of equipment are required to complete the whole process of the elbow sleeve, which not only has a high production cost, but also has a low production efficiency and a large floor space. [0003] In addition, during the pipe bending process, the U-shaped metal elbow is cut with a serrated blade. During the cutting process, due to the thickness of the blade itself, at least twice the wall thickness of the serrated blade is required when cutting a U-shaped metal elbow. Waste, and the cutting process with a serrated...

Problems solved by technology

Since the metal pipe fitting support plate is fixed, the metal pipe fittings will move on the metal pipe fitting support plate during the bending process and there will be friction between the two, and the metal pipe fittings will wear or even thin the pipe wall due to friction, which will affect the quality of the bent product , but also increase the energy consumption of the device due to friction
