Abstract

The invention discloses an efficient heating device for the ends of a torsion bar. The device comprises a power cabinet, a rack, a hydraulic pump, a hydraulic cylinder, a cooling protection mechanism and a pair of coil induction heating mechanisms for heating the ends of the torsion bar. The coil induction heating mechanisms are arranged on the rack. The power cabinet is connected with the coil induction heating mechanisms through cables. The rack is provided with a pair of supports, the coil induction heating mechanisms are arranged on the supports respectively, one support is fixed to the rack, and the other support is movably arranged on the rack. The coil induction heating mechanisms comprise induction coils and pipe barrels, and the induction coils are wound around the pipe barrels. The cooling protection mechanism comprises cooling water pipes, and the cooling water pipes and the induction coils are wound around the interiors of the pipe barrels side by side. The induction coils are hollow pipes, and the cooling water pipes are communicated with the hollow pipes. Induction heating efficiency is high, time and labor are saved, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of torsion bar processing, in particular to a high-efficiency heating device for the end of a torsion bar. Background technique [0002] Both ends of the torsion bar need to be headed. When processing the pier, both ends of the torsion bar need to be heated, and after heating, both ends are simultaneously piered on the pier machine. [0003] At present, the two ends of the torsion bar are heated by electricity or fire, first heating one end of the torsion bar and then heating the other end of the torsion bar. This heating method has the following disadvantages: high heating energy consumption, which is not conducive to energy saving, and high cost; low heating efficiency, long heating time, which affects production progress; two ends are heated successively, the heating temperature difference between the two ends is large, and the quality difference between the two ends is large , affecting the quality of ...
