Summary of the invention
The present invention is directed to the problems referred to above, a kind of torsion bar thermal treatment unit is provided, transmission rig in this thermal treatment unit can effectively drive torsion bar workpiece rotary heating, and the asynchrony phenomenon of minimizing belt in transmission process, thereby reduction energy consumption, raise the efficiency, make torsion bar spline position homogeneous heating, improve the torsion bar quality.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of thermal treatment unit of car transmissions torsion bar, comprise high frequency heat-treating machine, motor, transmission rig, the thermal treatment induction coil is housed on described high frequency heat-treating machine, it is characterized in that: described transmission rig comprises power wheel, the first carrying roller, the second carrying roller, belt; Described motor is connected with power wheel, and power wheel is connected with the first carrying roller, the second carrying roller respectively by belt, and torsion bar is shelved between the first carrying roller and the second carrying roller, and the spline position of torsion bar is positioned at described thermal treatment induction coil.
Preferably, the first carrying roller and the second carrying roller are positioned at the power wheel top and are arranged in parallel, and are convenient to rotate the torsion bar workpiece.
Preferably, the axis of described thermal treatment induction coil is parallel with the axis of the first carrying roller, the second carrying roller, is convenient to torsion bar workpiece spline position and stretches in the thermal treatment induction coil, and the spline position is heated evenly.
Preferably, described motor is connected with step-down gear, can guarantee that transmission rig speed can be too not high, is heated evenly torsion bar workpiece spline position.
The beneficial effect that the thermal treatment unit of torsion bar of the present invention can produce is: the transmission rig in this device rotates by the driven by motor power wheel, power wheel drives two carrying rollers by two belts simultaneously and rotates, thereby reduce the asynchrony phenomenon of belt in transmission process, reduce energy consumption, improved working efficiency; Two carrying rollers of this transmission rig drive the rotation of torsion bar workpiece towards a direction simultaneously, can effectively make the torsion bar workpiece rotate, be heated evenly, and improve the quality of torsion bar; Motor is connected with step-down gear, can guarantee that transmission rig speed can be too not high, further makes torsion bar workpiece spline position be heated evenly, and improves the quality of torsion bar; The thermal treatment induction coil axis of high frequency heat-treating machine is parallel with the axis of the first carrying roller, the second carrying roller, is convenient to shelve torsion bar, and torsion bar workpiece spline position is positioned at the thermal treatment induction coil, is convenient to the spline position and is heated evenly, and improves the quality of torsion bar.
