Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment, and particularly relates to a fitting heat treatment device. Background Art

[0002] Heat treatment refers to a metal hot working process in which materials are heated, held, and cooled in the solid state to obtain the desired microstructure and properties. Quenching is also a type of heat treatment. Specifically, it is a heat treatment process method in which steel is heated above the critical temperature, held for a certain time, and then cooled at a rate greater than the critical cooling rate to obtain an unbalanced structure mainly composed of martensite (or bainite or single-phase austenite can also be obtained according to needs). Quenching is the most widely used process method in the steel heat treatment process.

[0003] In the existing quenching devices, the workpiece is heated as a whole in a heating furnace and then quenched. However, this method has relatively high energy consumption. There is also local heating of the workpiece using electric heating. When quenching different workpieces, different devices need to be used or the device needs to be modified, and the versatility of the device is poor. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a fitting heat treatment device, including a quenching pool. One side of the quenching pool is fixedly connected with a first rod. A support sleeve is sleeved on the first rod. A first conveyor belt is horizontally arranged on the upper part of the support sleeve. A plurality of clamping units are arranged on the first conveyor belt. The clamping units are used to clamp and fix the workpiece, and the first conveyor belt conveys the workpiece to the heating area for heating treatment.

[0005] The upper end of the support sleeve is fixedly connected with a second rod. A cross bar is sleeved on the second rod. A sliding sleeve is sleeved on the cross bar. An induction coil is arranged at the lower end of the sliding sleeve. An electric current is passed through the induction coil, and eddy currents are generated in the workpiece passing through, thereby generating heat, that is, heating the workpiece. In the above structure, the specific position of the induction coil can be adjusted according to the shape and structure of the workpiece.

[0006] Preferably, a first bolt is threadedly connected to the lower part of the support sleeve, and the end of the first bolt abuts against the end of the first rod. A second bolt is threadedly connected to the end of the cross bar, and the end of the second bolt abuts against the second rod. A third bolt is threadedly connected to the upper end of the sliding sleeve, and the end of the third bolt abuts against the cross bar. By loosening the first bolt, the second bolt, and the third bolt, the positions of the support sleeve, the cross bar, and the sliding sleeve can be adjusted respectively, and finally the position of the induction coil. This setting can be applicable to workpieces of different specifications.

[0007] Preferably, a first motor is fixedly connected to the upper part of the support sleeve, and the output end of the first motor is in power connection with the first conveyor belt. Starting the first motor to drive the first conveyor belt to run realizes the conveying of workpieces. It should be noted here that the specific power connection is that the output end of the first motor is connected to one of the rotating shafts of the first conveyor belt.

[0008] Preferably, a second conveyor belt is inclinedly arranged inside the quenching pool, and a second motor is fixedly connected to the side wall of the quenching pool. The output end of the second motor is in power connection with the second conveyor belt. Similarly, the power connection form of the second motor and the second conveyor belt is the same as that of the first motor and the first conveyor belt above. After the heated workpiece falls into the quenching pool for quenching, it is sent out by the second conveyor belt.

[0009] Preferably, the clamping unit includes a housing. A first clamping plate is fixedly connected to the upper end of the housing. A second clamping plate is slidably arranged on one side of the upper end of the housing. A spring is fixedly connected inside the housing. The end of the spring abuts against the second clamping plate and pushes the second clamping plate towards the first clamping plate. That is, the first clamping plate and the second clamping plate are used to fix the workpiece.

[0010] Preferably, a fourth bolt is inserted through the lower part of the first clamping plate, and the fourth bolt is threadedly connected to the housing. This realizes the fixation of the first clamping plate.

[0011] Preferably, an electromagnet is fixedly connected inside the housing. The output end of the electromagnet abuts against the lower part of the second clamping plate. When the electromagnet is energized and operates, the second clamping plate is pushed away from the first clamping plate. When the workpiece heating is completed, the electromagnet operates, and the second clamping plate is pushed to release the workpiece, that is, the workpiece falls into the quenching pool.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The height of the support sleeve can be adjusted, the height of the cross bar can be adjusted, and the horizontal position of the sliding sleeve can also be adjusted. Finally, the position of the induction coil can be set to adapt to the heating of workpieces of different specifications.

[0014] 2. A clamping unit is provided, including a first clamping plate and a second clamping plate. The second clamping plate is controlled by an electromagnet and a spring. The spring keeps clamping the workpiece. After the workpiece heating is completed and it is conveyed above the quenching pool, the electromagnet operates to release the workpiece and let it fall into the quenching pool for treatment, which has the advantages of convenient clamping and fast quenching.
