Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment equipment, and in particular to a heat treatment equipment for bearing production. Background Technology

[0002] A bearing is a component used to support the rotating shaft of a machine. It allows the shaft to reduce friction during rotation while maintaining the shaft's precise position. Bearings are widely used in various mechanical equipment and are an indispensable and important component in modern industry. The heat treatment equipment used in bearing production is used to heat treat bearing parts. Its main purpose is to change the microstructure of the bearing material through processes such as heating and cooling, thereby improving the bearing's hardness, wear resistance, fatigue strength, and dimensional stability.

[0003] Existing heat treatment equipment typically places bearings on a treatment rack for heating. Due to the different sizes of the bearings being treated, the treatment rack cannot be precisely positioned according to the bearing size, resulting in unstable bearing position during heating. This leads to insufficient heating in some areas and uneven heating. Furthermore, after quenching, the temperature of the quenching liquid increases, reducing its cooling capacity and causing inconsistent cooling rates in different parts, thus reducing the overall heat treatment effect. Utility Model Content

Furthermore, after quenching, the temperature of the quenching liquid increases, and its cooling capacity decreases, leading to inconsistent cooling rates in different parts and reducing the overall heat treatment effect.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A heat treatment device for bearing production includes a treatment box, a quenching box installed below the treatment box, a shelf installed inside the treatment box, several sets of limiting rings fixed to the shelf, and a drive assembly installed outside the treatment box. A baffle is fixed to the upper end of the shelf to prevent the bearing from falling accidentally. Several sets of flame nozzles are installed inside the treatment box, and a monitoring rod is installed inside the quenching box to monitor the temperature of the quenching liquid in real time.

[0006] The beneficial effects of this utility model are as follows: By adjusting the placement plate and limiting ring according to different bearing sizes, the bearing position is ensured to be stable during heating, avoiding uneven heating caused by inaccurate positioning, so that the heating temperature of different areas can be kept consistent. Combined with the real-time monitoring of the quenching liquid temperature by the monitoring rod, when the temperature rises to a certain value, it promptly reminds the addition of cooling treatment to keep it within the optimal working temperature range, ensuring the stability of cooling capacity during quenching, ensuring the uniformity of hardness of parts, and improving the overall heat treatment effect.

[0009] Furthermore, a connecting block is fixed to the outer end of the shelf, and a positioning plate is provided on one side of the connecting block. The piston rod and the telescopic rod are fixedly connected to the shelf through the positioning plate.

[0010] Furthermore, a transfer pipe is installed at the outer end of the processing box. The transfer pipe is used to transfer fuel for heat treatment, and a docking plate is fixed to one end of the transfer pipe.

[0011] Furthermore, a testing box is installed at the outer end of the quenching box, and the testing box is electrically connected to the monitoring rod.

[0012] Furthermore, a sealing plate is installed on the processing box, and a positioning block is fixed to the outer end of the sealing plate. The sealing plate is fixedly connected to the processing box through the positioning block. A heat-resistant plate is fixed to the bottom of the sealing plate, and the sealing plate is fastened and fixed to the processing box through the heat-resistant plate.

[0013] Furthermore, a fixing plate is welded to the outer end of the processing box, and a limit screw is provided inside the fixing plate. The processing box is detachably connected to the quenching box through the fixing plate.

[0014] Furthermore, a discharge pipe is fixed to the outer end of the quenching box, and an electromagnetic valve is fixed to the outer end of the discharge pipe.

[0015] The beneficial effects of adopting the above-mentioned further solution are: by using a cylinder to drive the placement plate to automatically immerse it in the quenching box after the bearing is quenched, it is ensured that the placement plate can be quickly and accurately immersed in the quenching liquid after quenching, reducing the steps and time of manual operation and improving the overall heat treatment effect.

Next, the cover is closed, and the flame nozzle 12 in the treatment box 1 is turned on to heat the bearing. After the flame nozzle 12 has fully heated the bearing, the cylinder 10 drives the piston rod 7 to move the placement plate 3 downward, automatically immersing it in the quenching liquid in the quenching box 2 for quenching. This ensures that the placement plate 3 can be quickly and accurately immersed in the quenching liquid after quenching. Combined with the monitoring rod 15, the temperature of the quenching liquid is monitored in real time.
