Hydraulic bending forming device for aluminum positioning retainer rings of stabilizer bars

Abstract

The invention provides a hydraulic bending forming device for aluminum positioning retainer rings of stabilizer bars. The hydraulic bending forming device comprises a fixing support (1). Platforms (2) are arranged on the fixing support, a pair of retainer ring positioning blocks (3) which are positioned on the same horizontal line is arranged on the front surfaces of the platforms, the aluminum rings can be placed in the retainer ring positioning blocks, compressing devices are arranged above the retainer ring positioning blocks (3) and compresses the upper sides of the retainer ring positioning blocks (3) via compressing blocks (43), and two upper mold bending devices and two lower mold bending devices are arranged on the backs of the platforms (2). The hydraulic bending forming device has the advantages that the positioning retainer rings are made of aluminum, so that the hydraulic bending forming device can be in rotation circular motion, and external force can be exerted on the aluminum rings; as the positioning retainer rings are made of the aluminum, pressure which is exerted on the stabilizer bars during machining is far lower than deformation pressure generated when steel rings are used as positioning retainer rings of stabilizer bars, the performance of the stabilizer bars can be improved, and fracture failure risks of the stabilizer bars can be reduced.

Description

technical field [0001] The invention relates to a hydraulic device, in particular to a hydraulic device for hydraulically bending and forming an aluminum ring positioning retaining ring at the end of a stabilizer bar. [0002] Background technique [0003] In the production of automobile stabilizer bars, it is necessary to assemble a positioning retaining ring at the end to play the function of axial positioning. At present, in the automobile stabilizer bar product industry, a kind of two seamless steel pipes are generally used to make rings on the stabilizer bar. , A certain pressure is applied through the circular ring mold to make the two steel rings produce plastic deformation and symmetrically attach to the end of the stabilizer bar, and the adhesion force is greater than 2000N. Because it is a steel ring, the applied external force must be greater than the elastic deformation force of the steel ring. The external force is large and loaded on the stabilizer bar at the...

Problems solved by technology

Because it is a steel ring, the applied external force must be greater than the elastic deformation force of the steel ring. The external force is large and loaded on the stabilizer bar at the same time, so that the stabilizer bar produces a certain pre-bending stress, which directly increases the fatigue of the stabilizer bar product, and there is a breakage failure of the stabilizer bar. risks of
