Abstract

The embodiment of the utility model discloses a quenching sensor. The lower surface of the quenching sensor comprises a heating surface of a preheating area and a heating surface of a diathermanous soaking area along the axis direction of the quenching sensor, wherein the heating surface of the diathermanous soaking area is higher than the heating surface of the preheating area of the quenching sensor. In the quenching sensor, a heated workpiece is free from over-burned and overheated risk in the preheating area. When the heated workpiece is in the diathermanous soaking area, a distance between a heating end face of the heated workpiece and the heating surface of the diathermanous soaking area is longer, so that the waste heat between the heating end face of the heated workpiece and the heating surface of the diathermanous soaking area is quickly radiated, the surface of the workpiece is prevented from being overheated and the overheated risk is avoided. Thus, the quenching sensor provided by the utility model is higher in stability during a quenching process and is capable of increasing the quenching quality of products.

Description

A kind of quenching inducer

Technical field

The utility model relates to the HTFX technical field, more particularly, relates in particular to a kind of quenching inducer.

Background technology

Quenching inducer is the terminating unit that utilizes inductive heating principle that the quenching workpiece is heated.

The magnetizer of quenching inducer set inside passes to electric current, thereby produces magnetic field; Ferromagnetic substance is positioned in the magnetizer that passes to alternating current, because the effect of alternating magnetic field, the inside of ferromagnetic substance can produce induced potential, so in ferromagnetic substance eddy current; Because skin effect, eddy current are built up in the surface of ferromagnetic substance and are produced heat energy, thereby reach transformation temperature; Reach the purpose of quenching again through Quench.

As shown in Figure 1, Fig. 1 is the structural representation of a kind of quenching inducer of the prior art.

Quenching inducer of the prior art, its general structure comprise water inlet pipe 010, rising pipe 011, protection chamber 013, and the lower surface 012 of quenching inducer is designed to and the corresponding shape of the shape of product.

The effect in protection chamber 013 is that quenching inducer is carried out cooling protection, the too high and damage that causes of the temperature that prevents quenching inducer.

And the effect of water inlet pipe 010 and rising pipe 011 is water coolant to be imported protection chamber 013 protect chamber 013 with derivation, makes that the water coolant formation in the protection chamber 013 circulates.

The quenching inducer that uses in the prior art, its lower surface 012 comprise preheating zone hot face B and diathermanous soaking zone hot face A, and wherein, preheating zone hot face B and diathermanous soaking zone hot face A are identical apart from the distance between the upper surface that is heated workpiece.

Above-mentioned be heated workpiece and can be specially bolt, is that example is introduced the principle of work of quenching inducer below with the bolt:

Such as: heated bolt requires minimum induction hardening layer depth at 5mm～6mm, so the degree of depth of induction diathermic must reach 7mm～9mm; Because of the bolt hardened zone is the land portions sclerosis, the origin of heat of depth direction is from the thermal conduction of the sphere end face of bolt; The thermal source of the sphere end face of bolt comes the heat energy that eddy current is transformed in the self-inductor; During preheating, the temperature of preheating zone hot face B is lower than 800 ℃ to the sphere end face that is heated bolt, does not have overheated risk in the preheating zone.When being heated workpiece and being transferred to diathermanous soaking zone; The temperature of bolt end face is increasingly high, and this moment, the hypotelorism of the diathermanous soaking zone of the sphere end face distance hot face A of bolt; The waste heat of the sphere end face of bolt can not be led away timely, thereby can assemble a large amount of waste heats; Waste heat is assembled too much, can cause the sphere end face of bolt to produce the overheated and phenomenon of melting of burning, thereby cause the hardening depth of bolt sphere end face not reach processing requirement.

Therefore, the quenching inducer of available technology adopting, the less stable when it quenches, thus cause the quenching of product second-rate.

Therefore, how a kind of quenching inducer is provided, the stability when quenching to improve it, the quenching quality of raising product is the technical barrier that those skilled in the art need solve.
