Abstract
The utility model discloses a hollow shaft quenching sensor which is used for the intermediate-frequency integral quenching of hollow shaft products. The hollow shaft quenching sensor comprises a ring-shaped sensor main body and two sensor transition plates which are integrally welded with the sensor main body, wherein an insulating plate is arranged between the two sensor transition plates; a water spraying ring is arranged outside the sensor main body; a plurality of spraying holes facing a to-be-quenched hollow shaft are formed in the inner side of the water spraying ring; a quenching liquid pipe for supplying the quenching liquid to the water spraying ring is arranged on the water spraying ring. The hollow shaft quenching sensor is simple in structure and convenient in use; through carrying out the intermediate-frequency integral quenching to the hollow shaft with the sensor, a part can be machined in one time; not only the amount of the sensor is reduced, but also the disassembling and changing frequencies of the sensor in a quenching process are also reduced; meanwhile, the technique requirements and strength requirements of a drawing can be achieved, and the bending strength of the part is greatly improved. Therefore, the machining production efficiency is improved, the production cost is reduced, and the performance of the part is improved.
Description
Technical field
The utility model relates to a kind of tubular shaft quenching inducer, is applicable to axial workpiece to carry out whole mid-frequency induction hardening.
Background technology
For the hollow shaft type product in steyr middle bridge of heavy duty automobile, the finite space position and the effect that in order to reach it, in assembly, exist, so product self structure is designed to middle coupling part excircle dimension small in ends greatly and part hollow.Also require it to reach enough intensity simultaneously and come transmitting torque and higher contact strength, therefore, this part needs to be strict with from material, matrix and surface hardness.
In order to reach its surface strength requirement, process means is high-frequency quenching conventionally, and according to the quenching technology of part, requiring is in high-frequency apparatus, to carry out step quenching, the two ends of quenching while quenching, and do not quench in the position that middle cylindrical is large.The result of this processes is to have met drawing requirement, but the transmission due to quenching process heat energy, cause the middle not quench section of part to divide the reduction that has occurred hardness, there is Liao Ruan district, make the flexural strength of part be subject to very large impact, part is in easily do not quench from centre afterwards position fracture of use.
In addition, owing to processing at twice, need to change inductor block and process, production efficiency is not high.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of tubular shaft quenching inducer, and tubular shaft is taked to integral quenching, easy to operate, reduce the operating time, improved production efficiency, guaranteed drawing technical requirements and the intensity of part.
In order to achieve the above object, the technical solution of the utility model: a kind of tubular shaft quenching inducer, for the intermediate frequency integral quenching to hollow shaft type product, comprise the two inductor block rebounds that are circular inductor body and are welded in one with it, between two inductor block rebounds, be provided with insulcrete, in described inductor body, be provided with water spray ring outward, this water spray ring inner side is provided with some spray apertures towards tubular shaft to be quenched, and is provided with in water spray ring the quench fluid tube of supplying with hardening liquid to it.
Further, correspondence is provided with cooling water tank outside described two inductor block rebounds, and on this cooling water tank, correspondence is provided with cooling water intakeoutfall, and in described inductor body, be provided be connected with this cooling water tank from cooling-water duct.
Further, described quench fluid tube is three, and it is evenly located in the outer circumference of water spray ring.
Further, described sensor body inner side is taper.
Further, between the both ends of the surface of described inductor body and horizontal plane, be respectively the angle of 18 °～35 °; Preferably, the corresponding angle that is 25 °, 30 ° between the both ends of the surface of described inductor body and horizontal plane.
The beneficial effects of the utility model: simple in structure, easy to use; By it, tubular shaft is carried out to intermediate frequency integral quenching, once part can be machined, not only reduced the quantity of inductor block, also reduced the number of times that changes to inductor block in quenching technology process, meanwhile, can reach drawing technical requirements and requirement of strength, greatly improve spares bend intensity.Therefore, improve processing efficiency, reduced production cost, improved the performance of part.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
