Description

Technical Field

[0001] The utility model relates to the technical field of material mechanics, in particular to a bearing sleeve heat treatment temperature control device. Background Art

[0002] The heat treatment process of alloys is a process that changes the physical and chemical properties of metals or alloys by heating and cooling. It usually includes three stages: heating for solid solution, quenching, and aging precipitation. The alloy is heated to a sufficient temperature to dissolve the alloying elements in the matrix, forming a uniform solid solution. This process can improve the alloy's structure. Using water or oil as the quenching medium and rapidly cooling from the solid solution treatment temperature will retain the supersaturated state of the alloying elements in the matrix, thereby significantly improving the hardness and strength of the material. Heating the quenched alloy causes the alloying elements dissolved in the matrix to precipitate and form a fine precipitate phase. This process further enhances the hardness and strength of the material.

[0003] Existing heating solution dissolution devices generally use current control, control the output power with the current value, and calculate the calorific value with the power value. The device is easy to stabilize when the resistance wire tends to release heat uniformly, that is, when the heat generated is equivalent to the heat lost, the device remains stable. The advantage is that this type of heating device can maintain a stable temperature for a long time, which is convenient for long-term operation. The disadvantage is that if it is used for metal heat treatment solution, the heat absorption will destroy the stable state each time the metal product is put into it, resulting in temperature fluctuations. The temperature control is not accurate enough. If the temperature state needs to be reached again, it will take a long time. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 , the utility model provides a technical solution:

[0026] A bearing sleeve heat treatment temperature control device comprises a housing 1, a heating chamber disposed within the housing, a controller 2 disposed outside the housing 1, a pad 3 placed within the heating chamber, multiple bearing sleeves placed on the pad 3, and a cap 4 disposed above the heating chamber. This device can be used for heat treatment of metal products, specifically for heat solution treatment of bearing sleeves. The bearing sleeves are placed on the pad 3, and the pad 3 and bearing sleeves are then placed in the heating chamber. The heating temperature is adjusted using the controller 2, and the thermistor 15 on the cap 4 cooperates with the controller 2 to control the temperature.

[0027] Furthermore, a structural tube 5 is provided within the housing 1, and a high-temperature resistant tube 6 is installed within the structural tube 5. Insulating sand is filled between the housing 1 and the structural tube 5. A spiral groove is provided within the high-temperature resistant tube 6, and a heating resistor 7 is installed within the spiral groove. The high-temperature resistant tube 6 and the cushion 3 are both made of refractory materials. The high-temperature resistant tube 6 and the heating resistor 7 are arranged in a circular manner to wrap the cushion 3 and the bearing sleeve in the center, which can evenly heat the bearing sleeve and prevent excessive temperature differences on one side from affecting the solid solution effect.

[0028] Furthermore, the mat 3 comprises multiple sets of support plates 8 and two sets of connecting rods 9. The multiple sets of support plates 8 are fixedly connected by the connecting rods 9. A through-hole 10 is provided in the center of each support plate 8. The mat 3 is placed within the high-temperature-resistant cylinder 6 and surrounded by the heating resistor 7. The through-hole 10 in the center of the support plates 8 allows for hot air circulation and assists in removing the mat 3 from the heating chamber. A heat-conducting block 14 passes through the through-hole 10 at the top to facilitate heat conduction.

[0029] Furthermore, the capping cover 4 includes a heat-resistant top 11, a structural block 12, two sets of handles 13, a heat-conducting block 14 and a thermistor 15. The structural block 12 is processed with a convex ring corresponding to the high-temperature resistant tube 6. A through-type heat-conducting block 14 is provided in the center of the structural block 12, and two sets of handles 13 are provided on the side of the structural block 12. The structural block 12 is inserted into the top of the high-temperature resistant tube 6, and the heat-conducting block 14 is placed in the corresponding through hole 10 on the cushion 3. The side of the structural block 12 facing away from the high-temperature resistant tube 6 is provided with a heat-resistant top 11, and a circular groove is opened in the center of the heat-resistant top 11. The thermistor 15 is installed in the circular groove. The heat-resistant top 11 is coaxially fixedly connected to the structural block 12, and the outer end of the thermistor 15 is against the heat-conducting block 14. The heat conducting block 14 is used to conduct the temperature in the heating chamber to the thermistor 15. If the thermistor 15 is placed directly in the heating chamber, the temperature will be too high and the temperature will be frequently heated, which will cause the thermistor 15 to be damaged and result in a high error. The main function of the cap 4 is to seal the top of the heating chamber to prevent a large amount of heat from leaking out, resulting in low efficiency of the device or affecting the environment.

[0030] Furthermore, the controller 2 includes electronic components such as a display screen 16, multiple sets of control buttons 17, two sets of adjustment knobs 18, and an internal control circuit. The display screen 16 is a high-temperature resistant display screen. Two sets of adjustment knobs 18 are provided on one side of the display screen 16. Multiple sets of display screens 16 are provided on one side of the two sets of adjustment knobs 18. The thermistor 15 and the heating resistance wire 7 are both electrically connected to the controller 2. The circuit within the controller includes a current and voltage regulation circuit. The adjustment knob 18 can be used to linearly adjust the voltage value and current size. The device temperature can be manually controlled and adjusted, and is also used for zeroing and self-calibration. The control button 17 can be used to input the target temperature value. The internal circuit structure receives the information from the thermistor 15 and processes it to determine the temperature value in the heating chamber, and then automatically increases or decreases the output power value, resulting in precise temperature control.

[0031] Working principle: When using this device, multiple sets of bearing sleeves can be placed on multiple sets of support plates 8, and the bearing sleeves and pads 3 can be placed as a whole into the center of the high-temperature resistant cylinder 6. The heating resistance wire 7 converts electrical energy into thermal energy and releases heat to perform heat treatment and solid solution on the bearing sleeves. The controller 2 can be used to control the input target temperature, and the controller 2 controls the output power value to control the temperature in the heating chamber.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
