specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 to Figure 6 Describe this embodiment, this embodiment includes shaft 1, bearing 2, pressure ring 3, limit sleeve 4, washer 5, nut 6, roller frame 8, roller 9 and three screws 7, the axis of roller 9 is provided with The stepped hole, the stepped through hole is the bearing installation hole 9-1, the transition hole 9-2 and the inner hole of the roller 9-3. From the axial section of the roller 9, the outer surface of the roller 9 is an outwardly convex arc Surface 9-4, the bearing 2 is set in the bearing installation hole 9-1, the outer surface of the pressure ring 3 is a stepped cylinder, the stepped cylinder is respectively the compression section 3-1 and the connection section 3-2, and the axis of the pressure ring 3 There is a through hole 3-3 at the connecting section 3-2, and three countersunk nail holes 3-4 are evenly distributed on the connecting section 3-2. The pressing section 3-1 is arranged in the bearing i...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination image 3 and Figure 4 The present embodiment will be described. The cross-section of the clamping portion 8-1 of the present embodiment is a rectangle. During use, the clamping part 8-1 is clamped on the tool rest of the lathe, and the section of the clamping part 8-1 is designed as a rectangle for easy clamping. Other components and connections are the same as those in the first embodiment.

[0009] The working process of the present invention: according to the different dimensions of the outer diameter, ordinary lathes of different specifications are selected in the closing processing, the processing parts (pipe parts) are clamped on the lathe chuck, and clamped after alignment; the pipe parts The clamping part 8-1 on the turning closing and rolling device is clamped on the lathe tool holder, the axis line of the roller 9 is perpendicular to the axis line of the lathe main shaft, and the position of the turning closing ...

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...
