Forming and centering method of torsion beam of pipe fittings

Abstract

The invention discloses a method for forming and centering a torsion beam of a pipe fitting. The method comprises the following steps: step 1, preforming a tube blank, and the preformed tube blank has a roughly V-shaped or U-shaped cross section; step 2 , install stoppers on both sides of the cavity on the upper surface of the lower die, and install floating blocks near the end face of the lower die. The groove; step 3, put the preformed tube blank into the groove, and the tube blank is clamped by two stoppers at the same time to prevent overturning and complete the centering. By adopting the forming and centering method of the torsion beam of the pipe fitting of the present invention, the centering of the pipe blank can be ensured, the deviation can be prevented, and the machining accuracy of the torsion beam of the pipe fitting can be ensured.

Description

technical field [0001] The invention relates to the field of pipe fitting torsion beams, in particular, the invention relates to a forming and centering method of pipe fitting torsion beams. Background technique [0002] The torsion beam of the rear axle of the automobile is one of the key components of the automobile. Its main function is to balance the up and down jump of the left and right wheels, so as to reduce the shaking of the vehicle and keep the vehicle stable. Tilt stiffness. The components of the torsion beam of the traditional structure are mostly formed by sheet metal stamping, and the torsional stiffness of the beam is relatively small. Therefore, a stabilizer bar is added to increase its torsional stiffness. The torsion beam of the new structure adopts a tubular structure with a closed cross-section configuration, and the torsion Rigidity is higher, so the stabilizer bar is canceled. [0003] Compared with the pipe torsion beam, the torsion beam of the trad...

Problems solved by technology

However, the centering of the pipe fitting torsion beam in the prior art is inaccurate, and the tube blank is prone to deviation during the forming process, resulting in deviation of the finally formed pipe fitting torsion beam 100, such as Figure 4b As shown, it affects the forming accuracy of the product

[0006] In view of the existing centering problems in the processing process of the pipe torsion beam in the prior art, it is of great significance to provide a new forming and centering method of the pipe torsion beam
