Description

Technical Field

[0001] The utility model relates to the technical field of steel ball production, in particular to a steel ball production, processing and tempering device. Background Art

[0002] Tempering of steel balls during production and processing refers to the treatment of steel balls by heating and cooling during the production and processing of steel balls to change their structure and properties.

[0003] Tempering is a heat treatment process, the main purpose of which is to improve the hardness, toughness and strength of the steel ball by controlling the heating temperature and holding time so that it can meet the required performance requirements.

[0004] Steel balls need to be cooled after tempering during production and processing. The main function of cooling is to remove excess heat, stabilize the organizational structure, control hardness and toughness, and reduce internal stress. Cooling is an important part of the tempering process and helps improve the performance and quality of steel balls.

[0005] According to the "A Steel Ball Production, Processing and Tempering Device" proposed in CN 218532072 U, the steel ball production, processing and tempering device includes a bearing unit, an adjustment and positioning unit and a drive assembly unit, and also includes: a separation disturbance unit, which is used for the steel balls to be fully heated and quickly discharged and is movably arranged inside the bearing unit; the separation disturbance unit includes a discharge cylinder, a disturbance rod and a disturbance strip, and the discharge cylinder is movably arranged inside the bearing unit. In the utility model, the disturbance strip is driven by the disturbance rod to synchronously disturb the steel balls of different layers in each layered interval one by one, and the relative movement and position change between the steel balls can further evenly heat them.

[0006] Although this device can make the steel ball heat evenly, the temperature of the steel ball is high, which is not convenient for further cooling operation, resulting in troublesome subsequent operations, and is not conducive to the steel ball to drive away residual heat, stabilize the organizational structure, and improve the performance and quality of the steel ball. Summary of the invention

[0007] In order to solve the problem that the existing steel balls cannot be cooled down quickly after being heated and the subsequent operation is troublesome, the utility model provides a steel ball production and processing tempering device, which can achieve rapid cooling of the steel balls after being heated and simplify the operation.

[0008] The technical solution is as follows: a steel ball production, processing and tempering device, characterized in that it includes a base, on which a heat-insulating cylinder and a cooling cylinder are arranged side by side, a heat-insulating baffle is arranged at the connection between the heat-insulating cylinder and the cooling cylinder, an heat-insulating cover connected to a driving mechanism is arranged at one end of the opening of the heat-insulating cylinder, the size of the heat-insulating cover is consistent with the inner diameter of the heat-insulating cylinder, a heating pipe is arranged on the inner wall of the heat-insulating cylinder, an annular ventilation plate is arranged in the cooling cylinder, an air inlet gap is left between the annular ventilation plate and the inner wall of the cooling cylinder, a cold air inlet connected to the air inlet gap is arranged on the outer wall of the cooling cylinder, and ventilation holes are evenly arranged on the annular ventilation plate.

[0009] Its further feature is that the heating tube is spirally arranged in the heat preservation tube;

[0010] A slide is provided at the opening of the heat preservation tube, and an arc-shaped guide groove matching with the heat preservation tube is provided on the slide;

[0011] The thermal insulation partition is movably mounted on the support frame;

[0012] The driving device is an electric push rod or a cylinder fixed to the stabilizing plate;

[0013] It also includes an annular net frame, in which a multi-layer annular net frame is arranged and a thread groove is arranged at the center position, and the circular net cover is installed in cooperation with the thread groove through the central thread column.

[0014] After the utility model is adopted, the steel ball that needs to be tempered is put into the heat preservation cylinder, which is covered and sealed with a heat preservation cover, and the inside of the heat preservation cylinder is heated by a heating pipe. After high-temperature heating, the heat preservation partition is opened, and the heat preservation cover steel ball is pushed into the cooling cylinder. Air is introduced into the annular ventilation plate through the cold air pipe, and then blown to the surface of the steel ball through the annular ventilation plate for rapid cooling, and finally taken out from the opening at the other end of the cooling cylinder, thereby realizing a continuous action from heating to cooling, achieving rapid cooling, and simplifying the operation.
