Abstract

The invention provides a torsion rod forming machine and a method for machining a torsion rod by using the torsion rod forming machine, belongs to the technical field of machine tools, and solves the problem of high manufacturing cost in a traditional vehicle safety belt force limiting torsion rod machining device. The torsion rod forming machine comprises a frame; the frame is provided with a clamping mechanism with a clamping mold and used for clamping a torsion rod blank; forming molds with end forming holes and extrusion rods inserted in the end forming holes are arranged on two sides of the clamping mold; and the frame is provided with a first hydraulic cylinder capable of driving the forming molds to butt against the side surface of the clamping mold and a second hydraulic cylinder capable of driving the extrusion rods to move in a direction of approaching the clamping mold. The torsion rod forming machine saves a lot of molds and punching mechanisms to largely reduce the manufacturing cost of the torsion rod forming machine; and the torsion rod forming machine is used for machining torsion rods to achieve the advantages of guaranteeing consistent quality of the torsion rods and improving the production efficiency.

Description

technical field

[0001] The invention belongs to the technical field of machine tools, and relates to an extrusion molding device, in particular to a torsion bar molding machine.

[0002] The invention belongs to the technical field of machine tools, and relates to an extrusion molding device, in particular to a method for processing a torsion bar by using a torsion bar forming machine. Background technique

[0003] The vehicle safety belt is a device used to ensure that passengers and the driver are injured when the vehicle body is hit violently to prevent the passengers from being ejected by the safety airbag. The ideal seat belt action process is: first, tighten it in time, and "press" the person on the seat without hesitation at the first moment of the accident. Then, relax moderately, and when the peak of the impact force has passed, or when the person has been protected by the airbag, the seat belt is properly loosened.

[0004] For this reason, people have designed a...
