Embodiment 1

[0033] figure 1 It is a structural schematic diagram of the supporting wheel of the present invention, figure 2 and image 3 An implementation form of Embodiment 1 of the present invention is shown.

[0034] Depend on figure 2 and image 3 It can be seen that the quenching device for the rollers of the present invention includes: a frame body 10 for providing a sealed and heat-insulated environment; a heating unit 20 for inductively heating the rollers 21; the heating unit 20 includes a The platform 22 carrying the supporting wheel 21, the induction coil body 23 for heating the supporting wheel 21 and the supporting shaft 26 for rotation: the platform 22 is located above the supporting shaft 26 and rotates under the drive of the supporting shaft 26; the induction coil The body 23 is a hollow column with the same shape as the supporting wheel 21. The size of the induction coil body 23 is just sleeved on the outer side of the supporting wheel 21; the induction coil body 23...

Embodiment 2

[0043] On the basis of Example 1, Example 2 is a quenching method using the quenching device for the roller provided in Example 1. Figure 4 It is a flow chart of the method for quenching a roller in the present invention, showing an implementation form of Embodiment 2 of the present invention. Depend on Figure 4 It can be seen that the quenching method steps of the roller 21 are as follows:

[0044] S1: place and position the supporting wheel 21 on the platform 22: rotate the rotating shaft 12, the groove 13 is separated from the protrusion 15, the cover plate 11 is opened, and the manipulator places the supporting wheel 21 on the platform 22 to the first limit block 221 and The second limit block 222 is just covered by the bottom inner ring of the supporting wheel 21; the rotating shaft 12 is rotated, the groove 13 is engaged with the protrusion 15, and the cover plate 11 is closed;

[0045] S2: Carry out high-frequency induction heating and medium-frequency induction hea...

Abstract

The invention discloses a quenching device of a supporting wheel. The quenching device of the supporting wheel comprises a frame body used for providing a sealing heat insulation environment, a heating unit and a cooling unit. The heating unit comprises a platform for bearing the supporting wheel, an induction ring body used for heating the supporting wheel and a supporting shaft used for rotating; the platform is located above the supporting shaft and is driven by the supporting shaft to rotate; the induction ring body is in a hollow columnar shape, is a column in the shape the same as that of the supporting wheel and is connected to the first inner side of the frame body in a sliding manner; the size of the induction ring body allows the induction ring body to be just arranged on the outer side of the supporting wheel in a sleeving manner; the cooling unit comprises a spraying cover, wherein the spraying cover and the supporting wheel are the same in shape, and the spraying cover is located above the platform and is arranged on the outer side of the induction ring body in a sleeving manner; the spraying cover is connected into a second inner side, corresponding to the first inner side, of the frame body in a sliding manner; and nozzles which are arranged in a matrix manner and are the same in size are formed in the inner side of the spraying cover and face the supporting wheel. The problem that in the prior art, the hardness of the quenched supporting wheel is not uniform is solved, and the beneficial effect that the hardness of the supporting wheel is uniform is achieved.

Description

technical field [0001] The invention relates to a metal material heat treatment process, and more specifically, the invention relates to a quenching device for a supporting wheel. Background technique [0002] The track roller is one of the four-wheel belts of the tracked construction machinery chassis. It is mainly used to carry the weight of large machinery such as bulldozers and excavators, so that the track can move forward along the rolling direction of the track roller. Since the working environment of the rollers is very harsh and the wear phenomenon is very serious, it is necessary for the rollers to have strong strength, hardness and wear resistance. In the prior art, a quenching process is usually adopted, and the hardness of the surface of the supporting wheel is increased by performing processes such as quenching and cooling on the surface of the supporting wheel. In the quenching process, induction coils are usually used to heat the rollers, and intermediate fr...
