Abstract

The invention provides automobile torsion rod spring rolling straightening quenching equipment which comprises a transmission device, a straightening device and a quenching device, wherein the straightening device is transmitted through the transmission device; a torsion rod spring is arranged inside the straightening device; and the quenching device is used for quenching the torsion rod spring. The automobile torsion rod spring rolling straightening quenching equipment is simple to operate; by utilizing the rolling function of a driving wheel and a driven wheel, not only the torsion rod spring is straightened at the red hot state in a pre-rolling mode, but also functions of pre-cooling and temperature equalizing to the torsion rod spring are achieved; three water spraying pipes which are uniformly distributed on a column which takes the axis of the torsion rod spring as the center are used for spraying water and quenching liquid to the torsion rod spring, with uniform quenching and small thermal stress. The automobile torsion rod spring rolling straightening quenching equipment has the advantages that the torsion rod spring is less bent, small in deformation and uniform in hardness; the overall straight linearity is less than 0.5mm; and meanwhile the fatigue resistance of the automobile torsion rod spring is improved, and the looseness deformation is reduced.

Description

technical field [0001] The invention relates to the field of manufacturing auto parts and accessories, in particular to torsion bar spring rolling straightening and quenching equipment for turning over an automobile cab. Background technique [0002] Existing automobile cab flipping is quenched with torsion bar springs, mainly including hanging type vertically entering quenching liquid, horizontally entering quenching liquid and high-frequency induction quenching three ways. Hanging quenching, there will be disadvantages such as uneven hardness on the top and bottom of the workpiece, "S" shape bending, and it is difficult to straighten; horizontal horizontal quenching, due to the different cooling capacity of the workpiece, is prone to deformation; high-frequency induction quenching, there will be The phenomenon that only the surface of the torsion bar is hardened but the core cannot be hardened. Contents of the invention [0003] In view of the above shortcomings, the pr...
