Abstract
The utility model relates to a vehicle semi-axle medium-frequency induction hardening sensor, in particular to a vehicle semi-axle medium-frequency induction hardening device and belongs to the field of technical heat treatment. The sensor comprises an induction coil and a magnetizer, wherein, a cooling structure is arranged on the induction coil, and a spigot groove is arranged at the connecting point of the lower end of the induction coil and the cylindrical surface; the hardening and heating inner hole of induction coil takes a shape of a cylinder, the height of which is four to eight mm; a magnetizer is arranged on the upper end of the induction coil; the spigot groove is a rectangular indentation. The utility model can increase the depth of hardened layer at the shaft neck in semi-axle hardening to meet the design requirements for uniform transitional induction coils. Furthermore, the utility model has the advantages of simple structure, convenient operation, and the stable quality of hardened products.
Description
(1) technical field
The utility model relates to a kind of automobile axle shaft mid-frequency induction hardening device, belongs to the thermal treatment process technology field.
(2) background technology
In the automobile finished product, automobile axle shaft is a kind of very important key components and parts, therefore require very high to process of thermal treatment, to the semiaxis mid-frequency induction hardening of flanged dish the time, usually adopt the inductor block of imitative type class or whole heating-type, but imitative type class inductor block is being handled axle journal round-corner transition place, and case depth is not enough and transition is inhomogeneous; The inductor block of whole heating-type is very big to the power requirement of equipment, and the insufficient strength of inductor block.
(3) summary of the invention
The utility model is at the deficiencies in the prior art, provide a kind of make half shafts portion have very dark hardened layer and axle journal round-corner transition place hardened layer dark and can transition evenly, plant capacity is required less automobile axle shaft mid-frequency induction hardening inductor block.
The utility model is achieved through the following technical measures.
This inductor block comprises induction coil and magnetizer, and cooling structure is arranged on the induction coil, and the junction of the lower cylindrical face of the lower end of induction coil and endoporus is provided with the seam groove, induction coil quenching heating endoporus is cylindrical, and it highly is 4-8mm, and the upper end of induction coil is provided with magnetizer.
Described seam groove is a rectangular indentation.
The utility model is provided with the seam groove with the junction of the lower cylindrical face of the lower end of inductor block induction coil and endoporus, has the effect of sealing leakage field.Because it highly is during less than 4mm for an endoporus, axle portion heating penetration depth is not enough, and during greater than 8mm, it is too many that magnetic line of force concentrates on bar portion, influence ring flange axle journal place to heat; Induction coil on inductor block upper end is provided with magnetizer, and purpose is for the regional current density near the fillet of semiaxis is increased, and makes axle journal be in to be on 45 ° the straight line electric current heat penetration with axis to go into the degree of depth and increase greatly, can improve the depth of hardening zone at diameter of axle place.Principle of work is as follows: after the induction coil energising, the annular effect that produces electric current produces the ring-type eddy current in half shafts portion, utilize the resistive heating of metal self.During heating, regulate the power supply appropriate output power, workpiece moves with certain speed, regulates the quenching technology condition, and the hardened layer of half shafts portion and axle journal round-corner transition place hardened layer are deepened and even transition.The depth of hardening zone at axle journal place when using the utility model may improve semiaxis to quench meets design requirement and the inductor block induction coil of even transition, has advantages such as simple in structure, easy to use, quenching products obtained therefrom steady quality.
(4) description of drawings
Accompanying drawing is the utility model schematic cross-section.
Wherein, 1, magnetizer, 2, the seam groove, 3, induction coil, 4, induction coil inner chamber.
(5) embodiment
Embodiment: as shown in drawings, form by induction coil 3 and magnetizer 1, induction coil 3 endoporus height is 6mm, on the induction coil 3 cooling structure is arranged, described cooling structure is that induction coil inner chamber 4 is used as cooling-water duct, the junction of the lower cylindrical face of the lower end of induction coil 3 and endoporus is provided with 2 * 2mm rectangle seam groove 2, and magnetizer 1 is in the upper end of induction coil 3.Semiaxis depth of hardening zone behind induction quenching is 8.4mm, and axle journal fillet place is 5.2mm along being on 45 ° the straight line from the surface to the HRC40 quench-hardened case with axis, satisfies and produces needs, and quality is guaranteed.
Claims (2)
1, a kind of automobile axle shaft mid-frequency induction hardening inductor block comprises induction coil and magnetizer, cooling structure is arranged on the induction coil, it is characterized in that, the junction of the lower cylindrical face of the lower end of induction coil and endoporus is provided with the seam groove, induction coil quenching heating endoporus is cylindrical, it highly is 4-8mm, and magnetizer is in the upper end of inductor block.
2, automobile axle shaft mid-frequency induction hardening inductor block according to claim 1 is characterized in that, described seam groove is a rectangular indentation.
