Special-shaped pipe end threaded rib forming device

Abstract

The invention discloses a special-shaped pipe end threaded rib forming device, and aims at providing the special-shaped pipe end threaded rib forming device which can solve the problem that the overall forming load is large and prolong the life. According to the technical scheme, the special-shaped pipe end threaded rib forming device is characterized in that the special-shaped pipe end threaded rib forming device comprises a clamping mechanism, a main tool body mechanism, a second driving mechanism, a rotating mechanism and an expanding thrust mechanism; the clamping mechanism comprises a mold body and a first driving mechanism used for driving the mold body to be closed to form a mold cavity to clamp a pipe; the main tool body mechanism comprises a tool fixture body rotatably connected with a tool bit assembly, the tool fixture body is provided with an elastic part abutting against the tool bit assembly, and the elastic part is used for enabling the output end of the tool bit assembly to have the initial position state capable of keeping an inclination angle; the second driving mechanism is used for driving the mold body to have the motion process of being close to or far away from the tool bit assembly; the rotating mechanism is linked with the tool fixture body to rotate; and the expanding thrust mechanism comprises a telescopic mechanism which is in transmission connectionwith the tool fixture body. The special-shaped pipe end threaded rib forming device is suitable for the technical field of mechanical devices.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to a threaded rib forming device at the end of a special-shaped pipe. Background technique [0002] At present, domestic thread rolling is not a conventional processing method for the processing of intercooler pipe fittings due to the hollow nature of intercooler pipe fittings. The hollow nature makes it extremely difficult to machine from the outside, requiring extreme force to roll the threads. The traditional pipe fitting rolling method realizes the automation of thread rolling to a certain extent, which greatly improves the processing efficiency of automotive intercooler pipe fittings. It adopts the way that the workpiece is rotated and the tool is fixed. The V-belt is used to drive the mold body of the workpiece to rotate, and at the same time, the tool uses the hydraulic cylinder to gradually approach the inner wall of the workpiece, thereby rolling out the thread...
