Turning, closing-up and rib rolling device for tube parts

Abstract

A turning, closing-up and rib rolling device for tube parts relates to closing-up and rib rolling devices for tube parts and solves the problem that a die used for closing up tube parts is complicated in structure, long in processing cycle, high in cost and poor in universality. Stepped holes are arranged at an axial center of a roller, the outer surface of the roller is an outwardly protruded arc surface, a bearing is arranged in a bearing mounting hole, a pressing section on a press ring is disposed in the bearing mounting hole, the end surface of the pressing section presses an outer ring of the bearing tightly, the press ring is connected with the roller through screws, a roller rack is of a shifting fork structure, an assembly consisting of the roller, the bearing and the press ring is disposed in a groove, a threaded end of a shaft sequentially penetrates through a lateral shaft mounting hole, a roller inner hole, an inner hole of the bearing, a through hole and another lateral shaft mounting hole, a limiting sleeve is sleeved on the shaft and presses an inner ring of the bearing tightly, a gasket is sleeved at the threaded end of the shaft, and a nut is connected with the threaded end of the shaft in a threaded manner. The turning, closing-up and rib rolling device of the invention is used for realizing turning, closing-up and rib rolling on serial tube parts with identical shapes and different outer diameters.

Description

technical field [0001] The invention relates to a bead rolling device for pipe parts. Background technique [0002] When the end face of the pipe parts is closed, the conventional stamping design special mold is often used for the processing method of closing. The structure of the special closing mold is complex, the processing cycle is long, and the cost is high. A set of closing molds can only be used for the closing of pipe parts of the same size. The versatility is poor, and it is not suitable for a series of pipe parts with the same shape and different outer diameters. The closing and rolling processing. Contents of the invention [0003] The purpose of the present invention is to solve the problem of complex mold structure, long processing cycle and high cost when closing pipe parts, a set of closing molds can only be used for closing pipe parts of the same size, and poor versatility. Turning and rolling device for pipe parts. [0004] The invention includes a sha...
