Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The present invention is an incremental rolling extrusion forming device for internal threads of pipe fittings, such as figure 1 As shown, it includes the motorized spindle housing 1 of the CNC machine tool. One side of the motorized spindle cabinet 1 is connected with a centering chuck 2. One side of the centering chuck 2 is fixed with a claw 3, and a pipe sample is fixed inside the claw 3. 4. The pipe fitting sample 4 is a thick-walled cylindrical metal blank, and the thick-walled cylindrical metal blank is fixed by the radial clamping force of the centering chuck 2 and the jaws 3, so as to ensure that the thick-walled cylindrical metal blank does not produce axial damage. Moving, the pipe fitting sample 4 is provided with a rolling forming tool wheel 5, one end of the rolling forming tool wheel 5 is connected with a driving device, ...

Abstract

The invention discloses a pipe fitting internal thread incremental rolling-extruding forming device. The pipe fitting internal thread incremental rolling-extruding forming device comprises an electricspindle box body of a numerically-controlled machine tool, a centring chuck is connected to one side of the electric spindle box body, a clamping jaw is fixed to one side of the centring chuck, a pipe fitting sample is fixed into the clamping jaw, a rolling-extruding forming tool wheel is arranged in the pipe fitting sample, a driving device is connected to one end of the rolling-extruding forming tool wheel, and a numerical control device of the numerically-controlled machine tool is connected to the electric spindle box body. The problem of low quality of an internal thread formed by current milling is solved.

Description

technical field [0001] The invention belongs to the technical field of pipe fitting forming equipment, and in particular relates to a pipe fitting internal thread incremental rolling extrusion forming device. Background technique [0002] As the most common connection form, threaded connection has many uses and is frequently used. The performance of the thread directly affects the service life and safety of the connected parts. Some process pipes in the project need to be connected with internal pipe threads. The thread processing method is milling, which belongs to the material removal processing method, and there is a problem of low thread processing quality. Therefore, there is a need for a device that can improve the quality of the internal thread of the pipe fitting, so as to improve the quality of the internal thread of the pipe fitting, improve the reliability of the connection of the internal thread of the pipe fitting and prolong the service life of the parts. Con...
