Abstract
The utility model holds a purpose to provide a quenching inductor for a rear bush bearing. The technical proposal can assure quenching quality and, on the other hand, the utility model is characterized in simple structure, easy manufacture, low cost and easy scale production. The utility model consists of a contact board, a cooling water inlet pipe, a cooling water outlet pipe, an effective heating conductor of inductor, a magnetic conduct body, an insulation board and a fastening bolt, wherein the contact board is connected with a transformer; the insulation board is sandwiched two poles of a power supply; the cooling water cools the water inlet pipe enters the effective heating conductor of inductor and then flows out the water outlet pipe. The utility model is characterized in that the effective heating conductor of inductor is coiled into a shape like a rear bush bearing; the magnetic conduct body is arranged at a boss where the effective heating conductor of inductor is coiled into a shape of rear bush bearing; the effective heating conductor of inductor is hollow.
Description
Technical field
The utility model is the induction quenching inductor block, belongs to the induction heat treatment technical field, particularly a kind of rear-wheel hub axle quenching inducer.
Background technology
The rear-wheel hub axle is key component and security personnel's part very important in the car, and its structural shape is the step shaft form, requires it to have reliable torsional fatigue strength and life-span.According to grasping external reinforcing process is fillet rolling, at present, round corner rolling process is also adopted in domestic production always, but the rear-wheel hub axle fatigue strength and the fatigue lifetime of this explained hereafter are relatively poor, can not meet design requirement, though security incident did not take place in actual entrucking, see that from going and finding out what's going on the stand test only realizes 4～60,000 times, exists potential safety hazard all the time.Theoretically, compare with round corner rolling process, the fatigue strength and the life-span of the raising part that the surface induction hardening reinforcing process can be by a relatively large margin, therefore, we had set about the R and D of induction quenching technology in the last few years.
Summary of the invention
The purpose of this utility model provides a kind of rear-wheel hub axle quenching inducer.Adopt this technical scheme to guarantee the heating quenching quality on the one hand, sensor structure is simple, easy to manufacture on the other hand, cost is low, be easy to production in enormous quantities.
Rear-wheel hub axle quenching inducer, it is by contact plate, the cooling water inlet pipe and water outlet pipe, the effective heating wires of inductor block, magnetizer, insulcrete, holding bolt is formed, contact plate is connected with transformer, insulcrete is installed between the two poles by holding bolt, the cooling water inlet pipe and water outlet pipe is made up of cooling water inlet pipe and cooling rising pipe, water coolant feeds the effective heating wires of inductor block by the cooling water inlet pipe, flow out by the cooling rising pipe again, it is characterized by: the effective heating wires of inductor block turns to the rear-wheel hub shape shaft, and the boss place that turns to the rear-wheel hub shape shaft in the effective heating wires of inductor block is equipped with magnetizer.
Positively effect of the present utility model in simple in structure, easy to manufacture, cost is low, be easy to produce in enormous quantities.And guaranteed the heating quenching quality.
Description of drawings
Fig. 1 is the sensor structure sketch.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Rear-wheel hub axle quenching inducer, it is by contact plate 1, cooling water inlet pipe and water outlet pipe 2, the effective heating wires 3 of inductor block, magnetizer 5, insulcrete 6, holding bolt 4 is formed, cooling water inlet pipe and water outlet pipe 2 is made up of cooling water inlet pipe and cooling rising pipe, contact plate 1 is connected with transformer, insulcrete 6 is installed between the two poles by holding bolt 4, water coolant feeds the effective heating wires 3 of inductor block by the cooling water inlet pipe, flow out by the cooling rising pipe again, it is characterized by: the effective heating wires 3 of inductor block turns to the rear-wheel hub shape shaft, the boss place that turns to the rear-wheel hub shape shaft in the effective heating wires 3 of inductor block is equipped with magnetizer 5, and the effective heating wires 3 of inductor block is the lead of hollow.
Its embodiment and working process are: contact plate 1 is made by copper sheet, its effect is that rear-wheel hub axle quenching inducer is connected with transformer, guarantee that electric current of intermediate frequency flows to the effective heating wires 3 of inductor block by contact plate 1, insulcrete 6 makes two poles separately, has played insulating effect; Water coolant feeds the effective heating wires 3 of inductor block by the cooling water inlet pipe, is flowed out by the cooling rising pipe again, has played the refrigerative effect; The effective heating wires 3 of inductor block is formed by square copper tube coiling, part 7 rotations during work, the electric current of intermediate frequency of nearly kiloampere flows through at the relative free area of effective heating wires 3 of inductor block and part, in order to guarantee heats, the effective heating wires 3 of inductor block and be heated between the part 7 and leave certain interval.
