A device for forming threaded ribs at the end of a special-shaped pipe

Abstract

The invention discloses a threaded rib forming device at the end of a special-shaped pipe, aiming to provide a threaded rib forming device at the end of a special-shaped pipe that solves the problem of large forming load and prolongs the service life. The main points of the technical scheme include: clamping Mechanism, which includes a mold body, and drives the first drive mechanism for clamping the mold body to form a mold cavity to clamp the pipe; the specific mechanism of the main knife includes a tool holder body that is rotatably connected to a cutter head assembly, and the tool holder An elastic piece against the cutter head assembly is installed on the body, and the elastic member makes the output end of the cutter head assembly have an initial position state of maintaining an inclination angle; a second driving mechanism drives the mold body to have a position close to or away from the The movement process of the cutter head assembly; the rotation mechanism, which is linked to the rotation of the tool holder; the diameter-expanding thrust mechanism, which includes a telescopic mechanism connected with the tool holder, and the present invention is applicable to 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...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies and defects of the existing technology, a special-shaped pipe end thread rib forming device is provided, which solves the problem of large overall forming load, avoids excessive friction in the initial stage of processing, protects the motor, and prolongs the service life. At the same time, High stability during processing, which is conducive to the precise forming of threads and improves production efficiency
