Thermomechanical treatment induction through heating rotary device for torsion rod springs

Abstract

The invention discloses a thermomechanical treatment induction through heating rotary device for torsion rod springs. The thermomechanical treatment induction through heating rotary device comprises a bracket cylinder, an inductor cylinder, a variable frequency spindle box, a center base cylinder, an induction heater, a bracket, a left V-shaped center and a right V-shaped center. The bracket is fixedly installed at the telescopic end of the bracket cylinder. The induction heater is fixedly installed at the telescopic end of the inductor cylinder. The right V-shaped center is fixedly installed at the telescopic end of the center base cylinder. The left V-shaped center is in transmission connection with an output shaft of the variable frequency spindle box. The left V-shaped center and the right V-shaped center are located on the two sides below the induction heater correspondingly. The thermomechanical treatment induction through heating rotary device is reasonable in structure and wide in applicability; the torsion rod springs rotate in the thermal treatment process, the whole torsion rod springs of different appearances can be uniformly heated, it can also be avoided that under-heating or spline part overheating structures happen to center holes in the two ends, the right V-shaped center has the regulation performance, the bracket can support the torsion rod springs through the bracket cylinder, and heating deformation bending is prevented.

Description

【Technical field】 [0001] The invention relates to the technical field of torsion bar spring production equipment, in particular to a torsion bar spring deformation heat treatment induction penetration heating rotating device for overcoming the quenching deformation and bending of the torsion bar spring. 【Background technique】 [0002] As an elastic element, torsion bar spring is widely used in the suspension of modern automobiles, and is used in cars, trucks and off-road vehicles. Compared with the leaf spring, the torsion bar spring has a series of advantages: the torsion bar spring has high energy storage per unit mass, which can reduce the mass of the car and save materials; The spring-loaded quality is beneficial to improve the ride comfort of the car; when applied to the front suspension of a front-drive car, the torsion bar spring can be arranged longitudinally to leave room for the swing axle of the front drive axle. However, torsion bar springs have strict requireme...
