Description

Technical Field

[0001] The invention relates to the technical field of motor manufacturing, and in particular to a heat treatment device and a heat treatment method for an asynchronous motor rotor punching sheet. Background Art

[0002] The rotor is the rotating part of the motor, which is composed of components such as the rotor core, rotor winding and shaft. Its function is to obtain rotational torque under the action of a rotating magnetic field. The rotor is divided into a squirrel cage rotor and a wound rotor according to its structure. The squirrel cage rotor is composed of a rotor cage and a rotor core. The rotor core is composed of a number of iron sheets with openings that are riveted together in a stacked manner. The openings on the iron sheets are butt-jointed to form rotor core bar slots. There are two main forms of rotor cages. One is to install copper bars in the rotor core bar slots and weld the two ends with rotor end rings. The other is to form the rotor cage by cast aluminum or cast copper.

[0003] A large-scale shielded motor rotor punching hot lamination process with application number 202210763167.8 includes the following steps: S1, using an automatic sheet sorting device to automatically sleeve and stack multiple rotor punchings on a positioning shaft, and the automatic sheet sorting device automatically aligns the wire grooves of the multiple rotor punchings; S2, moving the positioning shaft with stacked rotor punchings into a heating device, and a dispersion device is provided in the heating device, and the dispersion device is used to increase the spacing between the multiple rotor punchings on the positioning shaft. However, when the rotor punchings are heat treated in this process, the rotor punchings are often in a stacked state, and the internal heating effect of the rotor punchings is poor, thereby making the heat treatment effect worse.

DETAILED DESCRIPTION

[0032] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0033] like Figures 1 to 5 As shown, an asynchronous motor rotor sheet heat treatment device of the present invention comprises a heat treatment component 1 and a rotor sheet 7, a base 3 is provided at the lower end of the heat treatment component 1, a round rod 2 is provided in the center of the heat treatment component 1, a driving component 4 is provided at one end of the round rod 2, and an adjusting component 5 is provided at the other end of the round rod 2, a debris collection component 6 is provided at the top of the base 3 at the lower end of the adjusting component 5, the round rod 2 is suspended with the assistance of the adjusting component 5 and the driving component 4, the rotor sheet 7 is sleeved on the round rod 2, the round rod 2 is tilted with the assistance of the adjusting component 5, and after the round rod 2 is tilted, the rotor sheet 7 will slide along the round rod 2 into the heat treatment component 1, and the rotor sheet 7 moving on the round rod 2 is heat treated with the assistance of the heat treatment component 1, and the rotor sheet 7 after the heat treatment is completed slides from the end of the round rod 2 to the debris collection component 6, and the rotor sheet 7 will vibrate when it falls on the debris collection component 6, and the metal oxide on the surface of the rotor sheet 7 is dropped with the assistance of the vibration, thereby improving the heat treatment effect of the equipment on the rotor sheet 7.

[0034] The adjustment component 5 includes an electromagnetic ring 501, and the round rod 2 is concentric with the electromagnetic ring 501. The side of the electromagnetic ring 501 close to the strong magnetic core is opposite to the magnetic pole of the strong magnetic core. When the electromagnetic ring 501 is energized, a magnetic field will be generated, and the side of the electromagnetic ring 501 close to the strong magnetic core is opposite to the magnetic pole of the strong magnetic core. Therefore, there is a magnetic attraction between the electromagnetic ring 501 and the strong magnetic core at the side end of the round rod 2.

[0035] The driving assembly 4 includes a driving motor 401, and a magnetic coupling driving disk 402 is arranged at the output end of the driving motor 401. A magnetic coupling driven disk 403 is arranged on the side of the round rod 2 close to the driving assembly 4. The magnetic coupling driving disk 402 and the magnetic coupling driven disk 403 have opposite magnetic poles on the side close to each other. Since the magnetic coupling driving disk 402 and the magnetic coupling driven disk 403 have opposite magnetic poles on the side close to each other, the magnetic coupling driving disk 402 and the magnetic coupling driven disk 403 are connected. There is a magnetic attraction between the driven disk 403 of the coupling, and there is also a magnetic attraction between the electromagnetic ring 501 and the strong magnetic core at the side end of the round rod 2. Therefore, the round rod 2 can be suspended under the action of the magnetic attraction on both sides. After the drive motor 401 is started, the output end of the drive motor 401 will drive the rotation of the magnetic coupling drive disk 402, and the rotation of the magnetic coupling drive disk 402 will drive the rotation of the magnetic coupling driven disk 403 with the assistance of magnetic force, thereby rotating the round rod 2.

[0036] The debris collection assembly 6 includes a collection box 601, which is arranged on the base 3. A filter screen 602 is arranged on the top of the collection box 601. A slope is arranged on the side of the collection box 601 away from the drive assembly 4. The filter screen 602 extends to the slope. When the rotor punching 7 moves from one end of the drive motor 401 to the end of the electromagnetic ring 501 on the round rod 2, the rotor punching 7 will fall from the round rod 2, and the fallen rotor punching 7 will fall on the filter screen 602 to generate vibration. With the assistance of vibration, the metal oxide on the surface of the rotor punching 7 will fall off, and the fallen metal oxide will pass through the filter screen 602 and enter the collection box 601.

[0037] An air suction pipe 603 is provided at the side end of the collecting box 601, a filter cover is provided on one side of the air suction pipe 603 located inside the collecting box 601, an opening is provided on the side of the collecting box 601 away from the air suction pipe 603, a collecting bucket is provided inside the collecting box 601, and an air suction pump is provided at the side end of the air suction pipe 603. When the air suction pump is started, suction will be generated in the air suction pipe 603, so that downward wind force is generated at the filter 602. With the assistance of the wind force, the metal oxides can pass through the filter 602 more smoothly, and the metal oxides will fall into the collecting bucket. After the metal oxides in the collecting bucket are collected, the collecting bucket can be taken out from the opening at the side end of the collecting box 601 for cleaning, thereby improving the convenience of using the equipment.

[0038] A support 404 is provided on the base 3, and a driving motor 401 is provided on the top of the support 404. The support 404 is provided on the side of the heat treatment component 1 away from the debris collection component 6. The driving motor 401 is provided on the top of the support 404 so that the driving end of the driving motor 401 is concentric with the electromagnetic ring 501, thereby making the use of the equipment more stable.

[0039] The heat treatment component 1 includes a mounting seat 101, which is arranged on a base 3. A heat treatment chamber 102 is arranged on the mounting seat 101. An annular heating ring 103 is arranged in the heat treatment chamber 102. The heat treatment chamber 102 is provided with a through hole in the direction of the round rod 2. The annular heating ring 103 is concentric with the through hole. There are multiple annular heating rings 103. The round rod 2 passes through the through hole and the annular heating ring 103. The external thread 201 on the round rod 2 is located in the heat treatment chamber 102. Heat is generated when the annular heating ring 103 is energized. When the rotor punching 7 slowly slides with the inclination of the round rod 2, when the rotor punching 7 slides into the middle of the annular heating ring 103, the rotor punching 7 is heat treated with the assistance of the annular heating ring 103, thereby improving the convenience of equipment use.

[0040] A mounting frame 502 is provided on the top of the heat treatment chamber 102. The mounting frame 502 is N-shaped. The electromagnetic ring 501 is provided inside the mounting frame 502. The electromagnetic ring 501 is installed through the mounting frame 502, so that the electromagnetic ring 501 is more stable during use.

[0041] A transport component 8 is provided on the side of the debris collection component 6 away from the heat treatment component 1, and the transport component 8 includes a limit groove 801, a roller is provided in the limit groove 801, a conveyor belt 802 is provided on the roller in the limit groove 801, and a limit plate 803 is provided on the side of the conveyor belt 802 away from the debris collection component 6. The conveyor belt 802 is driven by an external motor, and the rotor punching 7 falling on the collection box 601 will slide along the inclined surface on the collection box 601, and the rotor punching 7 will slide onto the conveyor belt 802, and be limited by the assistance of the limit plate 803. As the external motor is driven, the conveyor belt 802 will carry the rotor punching 7 to the next process, thereby improving the convenience of equipment use.

[0042] During use of the present invention, the equipment is powered on, and then the round rod 2 is passed through the heat treatment component 1, so that the side of the round rod 2 provided with the strong magnetic core is close to the electromagnetic ring 501, and the side of the round rod 2 provided with the magnetic coupling driven disk 403 is close to the magnetic coupling driving disk 402, and the magnetic coupling driving disk 402, the magnetic coupling driven disk 403, the round rod 2 and the electromagnetic ring 501 are concentric, so that the round rod 2 is suspended, and then, the drive motor 401 is started, and the output end of the drive motor 401 drives the rotation of the magnetic coupling driving disk 402, and the rotation of the magnetic coupling driving disk 402 drives the rotation of the magnetic coupling driven disk 403, thereby rotating the round rod 2.

[0043] After the equipment starts to operate stably, the rotor punching 7 is passed through the gap between the magnetic coupling driving disk 402 and the magnetic coupling driven disk 403, so that the rotor punching 7 is suspended on the round rod 2, and then the current of the electromagnetic ring 501 is changed to make the side of the round rod 2 close to the electromagnetic ring 501 tilt downward. Due to the inclination of the round rod 2, the rotor punching 7 suspended on the round rod 2 will gradually slide and move, and the round rod 2 is in a rotating state, thereby reducing the friction between the rotor punching 7 and the round rod 2, making the movement of the rotor punching 7 smoother. At the same time, the rotation of the round rod 2 will also drive the rotor punching 7 to rotate slowly.

[0044] When the rotor punching 7 moves along the round rod 2 and passes through the annular heating ring 103, the annular heating ring 103 will heat the rotor punching 7, so that the rotor punching 7 is heat treated. In addition, due to the slow rotation of the rotor punching 7, the heat treatment effect of each part of the rotor punching 7 is better, thereby improving the heat treatment effect of the equipment.

[0045] As the rotor punching 7 moves along the round rod 2 and passes through the heat treatment component 1, the heat treatment processing of the rotor punching 7 is completed, and when the rotor punching 7 moves to the end of the round rod 2, the rotor punching 7 will fall from the round rod 2, and the fallen rotor punching 7 will fall on the filter screen 602 at the top of the collection box 601. When the rotor punching 7 contacts the filter screen 602, vibration will be generated. With the assistance of vibration, the metal oxide on the surface of the rotor punching 7 can be shaken off, and the shaken off metal oxide will pass through the filter screen 602 and enter the collection bucket in the collection box 601. Due to the assistance of the suction pump, the shaken off metal oxide will pass through the filter screen 602 more smoothly, and the vibration of the filter screen 602 will also clean the blocked holes in the filter screen 602, thereby improving the convenience of equipment use.

[0046] The rotor punching sheet 7 that falls on the collection box 601 will slide along the inclined surface of the collection box 601, and the rotor punching sheet 7 will slide onto the conveyor belt 802, and will be limited by the assistance of the limiting plate 803. With the drive of the external motor, the conveyor belt 802 will carry the rotor punching sheet 7 to the next process, thereby improving the convenience of equipment use.

[0047] During the use of the present invention, when a large number of rotor punchings 7 are suspended on the round rod 2 and piled up, during the heat treatment of the rotor punchings 7, the contact surfaces of the rotor punchings 7 will form a heat treatment dead angle, thereby making the heat treatment effect of the rotor punchings 7 worse, and when the stacked rotor punchings 7 slide off the round rod 2 together after the heat treatment, the rotor punchings 7 will fall on the filter screen 602 and roll down, so that the rotor punchings 7 after the heat treatment cannot be smoothly transported to the next process through the transport assembly 8, so that the heat treatment of the rotor punchings 7 cannot proceed to the next step. In order to solve this problem, the following solution is provided:

[0048] An inclination sensor is arranged inside the round rod 2, and an external thread 201 is arranged on the part of the round rod 2 located inside the heat treatment component 1. A strong magnetic core is arranged on the side of the round rod 2 close to the adjustment component 5. When the rotor punching 7 moves to the external thread 201 on the round rod 2, a stack is formed. As the round rod 2 rotates, the external thread 201 also rotates. The rotation of the external thread 201 causes the stacked rotor punchings 7 to be transported forward one by one, so that there are gaps between the rotor punchings 7 to ensure that the rotor punchings 7 can be fully heat treated, and the inclination sensor can detect the inclination angle of the round rod 2.

[0049] During use of the present invention, after the equipment starts to operate stably, the rotor punching 7 is passed through the gap between the magnetic coupling driving disk 402 and the magnetic coupling driven disk 403, so that the rotor punching 7 is suspended on the round rod 2. With the assistance of the inclination sensor, the inclination angle of the round rod 2 is detected. By adjusting the current of the electromagnetic ring 501, the side of the round rod 2 close to the electromagnetic ring 501 is tilted downward, so that the value of the inclination sensor reaches the threshold value. At this time, the rotor punching 7 suspended on the round rod 2 will gradually slide and move.

[0050] As the rotor punching 7 moves on the round rod 2, the rotor punching 7 will form a stack at the external thread 201 on the round rod 2. After the drive motor 401 is started, the output end of the drive motor 401 drives the magnetic coupling drive disk 402 to rotate. The rotation of the magnetic coupling drive disk 402 will drive the rotation of the magnetic coupling driven disk 403, thereby rotating the round rod 2. The rotation of the round rod 2 will drive the rotation of the external thread 201. When the external thread 201 rotates, the stacked rotor punchings 7 will be separated and transported forward one by one, so that the rotor punchings 7 can be better heat treated in the heat treatment component 1. As the rotor punching 7 moves through the external thread 201, the rotor punching 7 will continue to slide to the end of the round rod 2. It should be noted that the moving speed of the rotor punching 7 at the external thread 201 is less than the moving speed at the bare rod of the round rod 2.

[0051] When the rotor punching 7 moves to the end of the round rod 2 and falls, the round rod 2 will jump slightly. Therefore, the inclination sensor will detect this change of the round rod 2, so that the equipment can count the heat treatment processing of the rotor punching 7, and because the moving speed of the rotor punching 7 at the external thread 201 is less than the moving speed at the smooth rod of the round rod 2, the rotor punchings 7 will fall one by one from the end of the round rod 2 to ensure that the rotor punchings 7 will not be stacked and scattered, and to ensure that the rotor punchings 7 that fall on the filter 602 will slide down smoothly under the action of the inclined surface, and then the rotor punchings 7 can smoothly proceed to the next process.

[0052] The present invention also provides a heat treatment method for an asynchronous motor rotor punching device, comprising the following steps:

[0053] Step 1, power on the equipment, and then make the round rod 2 pass through the heat treatment component 1, so that the side of the round rod 2 provided with the strong magnetic core is close to the electromagnetic ring 501, and the side of the round rod 2 provided with the magnetic coupling driven disk 403 is close to the magnetic coupling driving disk 402, and the magnetic coupling driving disk 402, the magnetic coupling driven disk 403, the round rod 2 and the electromagnetic ring 501 are concentric, so that the round rod 2 is suspended, and the round rod 2 is rotated with the assistance of the driving component 4.

[0054] Step 2: Pass the rotor punching 7 through the gap between the magnetic coupling driving disk 402 and the magnetic coupling driven disk 403, so that the rotor punching 7 is suspended on the round rod 2, and then by changing the current of the electromagnetic ring 501, the side of the round rod 2 close to the electromagnetic ring 501 is tilted downward. Due to the inclination of the round rod 2, the rotor punching 7 suspended on the round rod 2 will gradually slide and move, and the round rod 2 is in a rotating state, thereby reducing the friction between the rotor punching 7 and the round rod 2, making the movement of the rotor punching 7 smoother. At the same time, the rotation of the round rod 2 will also drive the rotor punching 7 to rotate slowly.

[0055] Step three, when the rotor punching 7 moves along the round rod 2 and passes through the heat treatment component 1, the heat treatment component 1 will heat the rotor punching 7, so that the rotor punching 7 is heat treated, and due to the slow rotation of the rotor punching 7, the heat treatment effect of each part of the rotor punching 7 is better.

[0056] Step 4. As the rotor punching 7 moves along the round rod 2 and passes through the heat treatment component 1, the heat treatment processing of the rotor punching 7 is completed. When the rotor punching 7 moves to the end of the round rod 2, the rotor punching 7 will fall from the round rod 2, and the fallen rotor punching 7 will fall on the filter screen 602 at the top of the collection box 601. When the rotor punching 7 contacts the filter screen 602, vibration will be generated. With the assistance of vibration, the metal oxide on the surface of the rotor punching 7 can be shaken off, and the shaken off metal oxide will pass through the filter screen 602 and enter the collection bucket in the collection box 601. Due to the assistance of the suction pump, the shaken off metal oxide will pass through the filter screen 602 more smoothly, and the vibration of the filter screen 602 will also clean the blocked holes in the filter screen 602.

[0057] Step 5: The rotor punching 7 that falls on the collecting box 601 will slide down along the inclined surface of the collecting box 601, and the rotor punching 7 will slide onto the transport component 8 to move to the next process.

[0058] The main functions achieved by the present invention are: by setting components such as an external thread 201, an inclination sensor and an electromagnetic ring 501, the external thread 201 is rotated by rotating the round rod 2, and the rotor punchings 7 stacked on the round rod 2 are separated one by one by the rotation of the external thread 201, so as to ensure that the rotor punchings 7 can be better heat treated, and the rotor punchings 7 after the heat treatment are dropped one by one, so as to ensure that the rotor punchings 7 after the heat treatment are moved to the next step, and when the rotor punchings 7 fall, they will vibrate when in contact with the filter screen 602, and the metal oxides on the surface of the rotor punchings 7 after the heat treatment can fall off under the action of the vibration, and the blocked filter screen 602 can also be unblocked.

The shaken metal oxide will pass through the filter screen (602) and enter the collection bucket in the collection box (601). Due to the assistance of the suction pump, the shaken metal oxide will pass through the filter screen (602) more smoothly, and the vibration of the filter screen (602) will also clean the blocked holes in the filter screen (602); Step 5: The rotor punching piece (7) that falls on the collection box (601) will slide down along the inclined surface of the collection box (601), and the rotor punching piece (7) will slide onto the transport component (8) and move to the next process.
