Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for grinding balls, and specifically to a heat treatment device for grinding balls. Background Technology

[0002] Grinding balls are a type of pulverizing medium used in ball mills to pulverize materials. During the manufacturing process, grinding balls undergo heat treatment in a heat treatment furnace. Heat treatment is a metal heat treatment process that enables materials to obtain the desired structure and properties, allowing grinding balls to achieve superior performance.

[0003] In most existing heat treatment furnaces, grinding balls are first placed in supports, and then the supports containing the grinding balls are stacked in the furnace. However, the heat treatment furnace is heated by heating wires laid on the furnace wall. As a result, the grinding balls placed on the supports are prone to uneven heating, which causes various differences in the surface properties of the grinding balls, reduces the quality of the grinding balls, and causes many inconveniences to the actual production of grinding balls.

[0004] In summary, existing heat treatment furnaces suffer from uneven heating of grinding balls, leading to variations in the surface properties of the grinding balls and reducing their overall quality. Utility Model Content

[0005] The purpose of this invention is to provide a heat treatment device for grinding balls, in order to solve the technical problem that in most existing heat treatment furnaces, the grinding balls are prone to uneven heating, which causes various differences in the surface properties of the grinding balls and reduces the quality of the grinding balls.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A ball grinding heat treatment device, comprising a base,

[0008] The base is provided with a heat treatment furnace and a support frame at the top, and the support frame is located on one side of the heat treatment furnace. The support frame is provided with a hydraulic telescopic column inside, and a lifting seat is provided at the top of the hydraulic telescopic column. Traction rods are symmetrically arranged on both sides of the lifting seat, and a sealing furnace cover for sealing the heat treatment furnace is provided at the bottom of the traction rod.

[0009] The lifting platform is equipped with a servo motor inside. The output end of the servo motor is provided with a rotating shaft that passes through the top of the sealed furnace cover. The bottom end of the rotating shaft is provided with a fan blade, and the fan blade is located inside the sealed furnace cover. The bottom of the fan blade is higher than the bottom of the sealed furnace cover.

[0010] Preferably, the top of the sealed furnace cover is provided with a heat insulation frame for supporting the servo motor.

[0011] Preferably, the heat insulation frame, the rotating shaft, and the fan blades are all made of materials that are poor conductors of heat.

[0012] Preferably, the top of the lifting seat is symmetrically provided with limit guide rails, and the top of the limit guide rails is provided with limit grooves.

[0013] Preferably, a sliding frame is slidably disposed on the limiting guide rail, and the sliding frame is located on both sides of the servo motor.

[0014] Preferably, the top of the sliding frame is provided with a protective cover for protecting the servo motor, and a rectangular groove matching the servo motor is provided on one side of the protective cover. The inner walls of the two sides of the rectangular groove are rotatably connected to a flip plate via a torque shaft.

[0015] Preferably, the inner wall of the heat treatment furnace is covered with an insulation layer, and the inner wall of the insulation layer is provided with heating wires.

[0016] Preferably, the bottom of the sliding frame is provided with a limiting slider that matches the limiting slide groove, and sleeves are symmetrically provided on the opposite sides of the limiting guide rails.

[0017] Preferably, the inner wall of the limiting slide groove is symmetrically provided with through grooves communicating with the sleeve, and the side of the limiting slider that is far apart from each other is symmetrically provided with positioning grooves.

[0018] Preferably, the sleeve has a telescopic shaft inside, one end of the telescopic shaft has a hemispherical head shaft that matches the positioning groove, and a return spring for supporting the hemispherical head shaft is sleeved on the outside of the telescopic shaft.

[0019] The beneficial effects of this utility model are:

[0020] 1. In this utility model, when the grinding balls are heated, the servo motor starts and drives the rotating shaft to rotate, which in turn causes the fan blades to rotate. The rotation of the fan blades can drive the air in the heat treatment furnace to circulate and flow, thereby promoting the flow of heat. This ensures that the grinding balls on different areas of the support can receive uniform heat, making the grinding balls heat evenly and ensuring the consistency of various properties on the outer surface of the grinding balls. This improves the quality of the grinding balls and provides great convenience for the actual production of grinding balls. In addition, the fan blades are located inside the sealed furnace cover, and the bottom of the fan blades is higher than the bottom of the sealed furnace cover. This setting can effectively avoid interference between the fan blades and the support during use.

[0021] 2. In this utility model, the protective cover can protect the servo motor and prevent collisions with external objects. The return spring provides elastic support to the hemispherical head shaft. In the initial state, the return spring pulls the telescopic shaft to extend. At this time, the hemispherical head shaft is engaged in the positioning groove on the limiting slider, thereby positioning the protective cover. When the servo motor needs to be repaired, the sliding frame can be pushed to slide along the limiting guide rail to move the protective cover away. At this time, the limiting slider slides in the limiting groove, and the initial positioning groove and the hemispherical head shaft disengage. After moving to the predetermined position, the hemispherical head shaft engages with another set of positioning grooves, re-fixing the protective cover. This realizes the positioning and movement of the sliding frame and ensures the stability of the device during operation. Attached Figure Description

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0029] like Figure 1-4 As shown, a ball grinding heat treatment device includes a base 1.

[0030] The base 1 is equipped with a heat treatment furnace 2 and a support frame 3 on its top. The support frame 3 is located on one side of the heat treatment furnace 2. The support frame 3 is equipped with a hydraulic telescopic column 4 inside. The top of the hydraulic telescopic column 4 is equipped with a lifting seat 5. The lifting seat 5 is symmetrically equipped with traction rods 6 on both sides. The bottom of the traction rods 6 is equipped with a sealing furnace cover 7 for sealing the heat treatment furnace 2.

[0031] A servo motor 9 is installed inside the lifting platform 5. The output end of the servo motor 9 is equipped with a rotating shaft 15 that passes through the top of the sealed furnace cover 7. A fan blade 16 is installed at the bottom end of the rotating shaft 15, and the fan blade 16 is located inside the sealed furnace cover 7. The bottom of the fan blade 16 is higher than the bottom of the sealed furnace cover 7. The inner wall of the heat treatment furnace 2 is covered with a heat insulation layer 17, and an electric heating wire 18 is installed on the inner wall of the heat insulation layer 17.

[0032] The base 1 serves as the supporting foundation for the entire equipment, ensuring the overall stability of the device during operation. The heat treatment furnace 2 is the core area for heat treating the grinding balls, used to store the grinding balls and supports. The extension and retraction of the hydraulic telescopic column 4 drives the lifting seat 5 to move up and down, which in turn raises and lowers the sealing furnace cover 7 via the traction rod 6, thus opening and sealing the heat treatment furnace 2. This effectively prevents heat loss and the entry of external impurities during heat treatment, improving heat treatment quality and efficiency. The insulation layer 17 reduces heat loss within the heat treatment furnace 2, improving heat treatment efficiency. The heating wire 18 heats up after being energized, providing a heat source for the heat treatment furnace 2. When the machine 9 starts, it drives the rotating shaft 15 to rotate, which in turn causes the fan blade 16 to rotate. The rotation of the fan blade 16 can drive the air in the heat treatment furnace 2 to circulate and flow in the furnace, thereby promoting the circulation of heat. This ensures that the grinding balls on the supports in different areas can receive even heat, making the grinding balls heat evenly and ensuring the consistency of various properties on the outer surface of the grinding balls. This improves the quality of the grinding balls and provides great convenience for the actual production of grinding balls. In addition, the fan blade 16 is located inside the sealed furnace cover 7, and the bottom of the fan blade 16 is higher than the bottom of the sealed furnace cover 7. This setting can effectively avoid interference between the fan blade 16 and the support during use.

[0033] In this embodiment, specifically, a heat insulation frame 8 for supporting the servo motor 9 is provided on the top of the sealed furnace cover 7. The heat insulation frame 8 can reduce the heat transfer from the heat treatment furnace 2 to the servo motor 9 and protect the servo motor 9 from high temperature.

[0034] In this embodiment, specifically, the heat insulation frame 8, the rotating shaft 15, and the fan blade 16 are all made of materials that are poor conductors of heat. The use of materials that are poor conductors of heat for the rotating shaft 15 and the fan blade 16 can reduce the transfer of heat to components such as the lifting seat 5 through the rotating shaft 15, thereby reducing the overall heat impact on the equipment.

[0035] In this embodiment, specifically, the top of the lifting seat 5 is symmetrically provided with limit guide rails 10, the top of the limit guide rails 10 is provided with limit grooves 11, a sliding frame 12 is slidably provided on the limit guide rails 10, and the sliding frame 12 is located on both sides of the servo motor 9. The top of the sliding frame 12 is provided with a protective cover 13 for protecting the servo motor 9, and a rectangular groove matching the servo motor 9 is provided on one side of the protective cover 13. The inner walls of the rectangular groove are rotatably connected to the flip plates 14 through torque shafts. The bottom of the sliding frame 12 is provided with a limit slider 19 matching the limit groove 11. Sleeves 20 are symmetrically provided on the side of the limit guide rails 10 that are far apart from each other. The inner wall of the limit groove 11 is symmetrically provided with through grooves 21 communicating with the sleeves 20. The side of the limit sliders 19 that are far apart from each other is symmetrically provided with positioning grooves 22. A telescopic shaft 23 is provided inside the sleeve 20, and one end of the telescopic shaft 23 is provided with a groove corresponding to the positioning groove. The hemispherical head shaft 24 and the telescopic shaft 23 are matched with each other. A return spring 25 is sleeved on the outside of the hemispherical head shaft 24 to support the hemispherical head shaft 24. The protective cover 13 can protect the servo motor 9 and prevent collision with external objects. The return spring 25 provides elastic support for the hemispherical head shaft 24. In the initial state, the return spring 25 pulls the telescopic shaft 23 to extend. At this time, the hemispherical head shaft 24 is engaged in the positioning groove 22 opened on the limiting slider 19, thereby positioning the protective cover 13. When the servo motor 9 needs to be repaired, the sliding frame 12 can be pushed to slide along the limiting guide rail 10 to move the protective cover 13 away. At this time, the limiting slider 19 slides in the limiting slide groove 11, and the initial positioning groove 22 is disengaged from the hemispherical head shaft 24. After moving to the predetermined position, the hemispherical head shaft 24 is engaged with another set of positioning grooves 22 to fix the protective cover 13 again. This realizes the positioning and movement of the sliding frame 12 and ensures the stability of the device during operation.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] The working principle of this utility model is as follows: The operator controls the hydraulic telescopic column 4 to extend, causing the sealed furnace cover 7 to rise and open the heat treatment furnace 2. Then, the bracket containing the grinding balls to be heat-treated is placed into the heat treatment furnace 2. The operator then controls the hydraulic telescopic column 4 to retract, causing the sealed furnace cover 7 to descend until it is tightly fitted to the heat treatment furnace 2, thus sealing the furnace 2. The heating wire 18 is energized to heat the grinding balls inside the furnace 2. Simultaneously, the servo motor 9 is started, driving the rotating shaft 15 to rotate, which in turn causes the fan blades 16 to rotate, circulating the gas inside the heat treatment furnace 2. When the servo motor 9 needs maintenance, the sliding frame 12 is pushed along the limit guide rail 10 to remove the protective cover 13, allowing the operator to perform maintenance on the servo motor 9. After the maintenance is completed, push the sliding frame 12 to slide in the opposite direction to reset the protective cover 13. After the heat treatment is completed, turn off the heating wire 18 and the servo motor 9. After the grinding balls cool down, control the hydraulic telescopic column 4 to extend so that the sealed furnace cover 7 rises, open the heat treatment furnace 2, and take out the heat-treated grinding balls.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
