Description

Technical Field

[0001] The invention relates to the field of frequency converter production, and in particular to a heat treatment device for parts used in frequency converter production. Background Art

[0002] During the production process of the frequency converter, the internal spring needs to be heat treated to improve its mechanical properties. The heat treatment step is to first put the spring fired in a high-temperature state into a coolant for quenching treatment, thereby increasing the hardness of the spring. After the quenching is completed, the spring is placed in a tempering box for heating again to increase the toughness of the spring and eliminate stress. For example, the Chinese patent No. CN116497191A discloses a spring processing quenching device, which uses a rotating impeller to perform suction treatment inside the inner cavity. The coolant enters the inner cavity through the through hole and flows out to the left, allowing the coolant to efficiently flow through the inside of the spring, thereby improving the cooling effect of the coolant on the inside of the spring.

[0003] However, a large amount of oxide scale will fall off during the quenching process. Since the pitch at both ends of the spring is small, the oxide scale falls into the gap at both ends of the spring, which makes it difficult to clean manually, thereby reducing production efficiency. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] A heat treatment equipment for parts used in inverter production, such as Figure 1-8 As shown, a heat treatment machine is included;

[0030] It also includes a fixed plate 101, a connecting tube 102, an electric push rod 103, a round tube 104, a disc 105, a fixed rod 106, a motor I 107, an arc-shaped sheet 108, a spring rod 109, a rectangular sheet 1010, a stopper 1013, a slider 1014 and a cleaning assembly; the heat treatment machine is connected to two fixed plates 101; each of the two fixed plates 101 is fixedly connected to a connecting tube 102; each connecting tube 102 is bolted with an electric push rod 103; each telescopic end of each electric push rod 103 is connected to a round tube 104; each connecting tube 102 is fixedly connected to a disc 105; each disc 105 is provided with an annular groove 1051; each annular groove 1051 is slidably connected to a plurality of sliders 101 4; each slider 1014 is fixedly connected to a fixing rod 106, and the fixing rods 106 on the two discs 105 are detachably connected; the circular tube 104 is bolted to a motor Ⅰ 107; the output shaft of the motor Ⅰ 107 is fixedly connected to a plurality of arc-shaped pieces 108; the circular tube 104 is fixedly connected to a plurality of spring rods 109; the telescopic end of each spring rod 109 is fixedly connected to a rectangular piece 1010, and the rectangular piece 1010 is slidably connected to the circular tube 104, and the arc-shaped piece 108 limits the rectangular piece 1010, and the rectangular piece 1010 is a metal spring piece; each disc 105 is fixedly connected to a stopper 1013; the connecting tube 102 is connected to a cleaning component for cleaning the spring body 6, and the cleaning component is connected to the circular disk 105.

[0031] The heat treatment machine includes a base 1, a quenching box 2, a tempering box 3, a conveyor 4, a hydraulic cylinder 5 and a heating box 7; the base 1 is fixedly connected to the quenching box 2; the base 1 is fixedly connected to the tempering box 3; the base 1 is bolted to the conveyor 4; the conveyor 4 is fixedly connected to the hydraulic cylinder 5, and the telescopic end of the hydraulic cylinder 5 is detachably connected to two fixed plates 101; the base 1 is fixedly connected to the heating box 7, and the heating box 7 is located on the left side of the quenching box 2.

[0032] It also includes a hollow tube 1011 and a motor II 1012; the telescopic end of the electric push rod 103 is fixedly connected to the hollow tube 1011, and the hollow tube 1011 is slidably connected to the connecting tube 102; the hollow tube 1011 is bolted to the motor II 1012, and the output shaft of the motor II 1012 is fixedly connected to the round tube 104, and the round tube 104 is fixedly connected to the disc 105.

[0033] Each rectangular piece 1010 is provided with a wedge-shaped edge portion 11 to facilitate the rectangular piece 1010 to enter the gaps at both ends of the spring body 6 .

[0034] It also includes a cleaning rod 1061; one of the discs 105 is connected to the cleaning rod 1061 and the cleaning rod 1061 is located outside the fixed rod 106, so that when the fixed rod 106 clamps the spring body 6 to be quenched, the spring body 6 is limited by the cleaning rod 1061 and the fixed rod 106 to prevent the spring body 6 from deforming during the quenching process.

[0035] The slider 1014 is arranged at an angle, so that the impurities in the annular groove 1051 are scraped off when the slider 1014 rotates.

[0036] The fixing rod 106 has a built-in heating wire.

[0037] It should be noted that, except for the electric parts, all the parts used in this device are made of high-temperature resistant materials. When in use, the two fixing plates 101 are manually disassembled and separated, and the fixing rods 106 on the two discs 105 are disassembled and separated. Then, the spring body 6 to be heat treated is inserted between the fixing rods 106 on the two discs 105 through an external clamp. Then, the fixing rods 106 on the two discs 105 are brought close to each other until the connection and fixation are completed, and the two fixing plates 101 are connected and fixed, and then the fixing rods 106 clamp and fix the spring body 6. Then, the two fixed plates 101 that are connected and fixed are installed to the telescopic end of the hydraulic cylinder 5. Then, the hydraulic cylinder 5 is controlled to make the two fixing plates 101 and the spring body 6 slowly move downward into the heating box 7, and then the spring body 6 is heated. After the heating is completed, the hydraulic cylinder 5 is controlled to move the two fixing plates 101 and the spring body 6 upward to a high position over the heating box 7. Box 7, then, control the conveyor 4 to make the hydraulic cylinder 5 drive the fixed plate 101 and the spring body 6 to move right to just above the quenching box 2, then, control the hydraulic cylinder 5 to make the two fixed plates 101 and the spring body 6 move slowly downward until the spring body 6 is completely immersed in the quenching liquid in the quenching box 2, and then quench the spring body 6. During quenching, a large amount of oxide scale will fall on the spring body 6 and the quenching liquid. After quenching is completed, control the hydraulic cylinder 5 to make the two fixed plates 101 and the spring body 6 move upward to be higher than the quenching box 2, then, control the conveyor 4 to make the hydraulic cylinder 5 drive the fixed plate 101 and the spring body 6 to move right, and then send the quenched spring body 6 into the tempering box 3 for tempering treatment. After tempering is completed, control the conveyor 4 to make the hydraulic cylinder 5 drive the fixed plate 101 and the spring body 6 to continue to move right, and send the tempered spring body 6 out of the tempering box 3 to complete the heat treatment.

[0038] After tempering is completed, the oxide scale on the spring body 6 needs to be removed. At this time, first control the two motors Ⅰ107 to start, and drive the corresponding arc-shaped piece 108 to rotate through the output shaft of the motor Ⅰ107, and then the arc-shaped piece 108 squeezes the rectangular piece 1010, and squeezes the rectangular piece 1010 from the round tube 104 into the gap at both ends of the spring body 6. The rectangular piece 1010 slides in the round tube 104, and the spring rod 109 is compressed by the rectangular piece 1010. Then, control the two electric push rods 103 to make the round tube 104 drive the corresponding rectangular piece 1010 to move to the side away from the center of the spring body 6, and then the rectangular piece 1010 stretches the two ends of the spring body 6 to increase the gap at both ends of the spring body 6. Then, control the cleaning component to remove the oxide scale on the surface of the spring body 6 and in the gap at both ends.

[0039] During the quenching process, the motor I 107 is controlled to extrude the rectangular sheet 1010 from the round tube 104 into the gaps at both ends of the spring body 6. Then, the motor II 1012 is controlled to start, and the round tube 104 and the rectangular sheet 1010 are driven to rotate by the output shaft of the motor II 1012. The rectangular sheet 1010 drives the fixing rod 106 and the slider 1014 to rotate in the annular groove 1051, so that the rectangular sheet 1010 cleans the oxide scale that falls into the gaps at both ends of the spring body 6 to prevent the oxide scale generated at both ends of the spring body 6 from falling into the gaps at both ends, so that too much oxide scale accumulates in the gaps at both ends, making it inconvenient for subsequent cleaning. When the rectangular sheet 1010 rotates in the gaps at both ends of the spring body 6, the block 1013 blocks the end of the spring body 6 to prevent the spring body 6 from rotating under the scraping force of the rectangular sheet 1010.

[0040] Since the spring body 6 is prone to deformation during the quenching process, the cleaning rod 1061 is located outside the fixing rod 106, so that when the fixing rod 106 clamps the spring body 6 to be quenched, the radial deformation of the spring body 6 is limited to avoid deformation of the spring body 6 during the quenching process.

[0041] Since the temperature of the spring body 6 after quenching is relatively low, if it is immediately placed in the high-temperature tempering box 3, the spring body 6 will be brittle and cracked due to the huge temperature difference. Therefore, the quenched spring body 6 is pre-heated by the heating wire of the fixed rod 106 to reduce the temperature difference between the spring body 6 and the tempering box 3 and improve the heat treatment efficiency.

[0042] Example 2

[0043] On the basis of Example 1, Figure 4-Figure 5As shown, the cleaning assembly includes a rotating tube 201, a gear ring 202, a gear 203, a motor III 204 and a rotating ring 206; one of the connecting tubes 102 is rotatably connected to the rotating tube 201, and the other connecting tube 102 is fixedly connected to the rotating tube 201; the rotating tube 201 rotatably connected to the connecting tube 102 is fixedly connected to the gear ring 202; the rotating tube 201 rotatably connected to the connecting tube 102 is bolted to the motor III 204; the output shaft of the motor III 204 is fixedly connected to the gear 203, and the gear 203 is meshed with the gear ring 202; the disc 105 is rotatably connected to the hollow rotating ring 206, and the rotating ring 206 is fixedly connected to the rotating tube 201, and the rotating ring 206 is fixedly connected to the cleaning rod 1061; each cleaning rod 1061 is provided with a plurality of spray holes 1062, and the cleaning rod 1061 is hollow, and the cleaning rod 1061 is connected to the hollow rotating ring 206.

[0044] The connecting pipe 102 and the rotating pipe 201 are connected to a cooler.

[0045] The steps of cleaning the spring body 6 after heat treatment by the cleaning assembly in Example 1 are as follows: first, the external pump is connected to the rotating ring 206, then, the motor I 107 is controlled to squeeze the rectangular sheet 1010 into the gaps at both ends of the spring body 6, and then the rectangular sheet 1010 stretches the two ends of the spring body 6 to increase the gaps at both ends, and the rectangular sheet 1010 temporarily fixes the spring body 6, then, the motor III 204 is controlled to start, and the output shaft of the motor III 204 drives the gear 203 to rotate, the gear 203 drives the gear ring 202 to rotate, and the gear ring 202 causes the rotating tube 201 to drive the rotating ring 206 and the cleaning rod 1061 to rotate, as shown in FIG. Figure 7 As shown, at the same time, the external pump is controlled to transport the cleaning liquid to the cleaning rod 1061 through the rotating ring 206, and finally the cleaning liquid is sprayed out from the spray hole 1062 to clean the oxide scale on the surface of the spring body 6 and the gaps at both ends.

[0046] Since the electric drive parts in the connecting tube 102 and the rotating tube 201 may overheat when placed in the heating box 7, a cooler is connected to the connecting tube 102 and the rotating tube 201, and the cooler passes the cooling liquid into the connecting tube 102 and the rotating tube 201, thereby cooling the electric drive parts in the connecting tube 102 and the rotating tube 201.

[0047] Example 3

[0048] On the basis of Example 2, Figure 3-Figure 4 As shown, blades 205 are also included; each cleaning rod 1061 located in the horizontal direction is fixedly connected with a plurality of blades 205.

[0049] The blades 205 are densely distributed.

[0050] Since the spring body 6 needs to be in a stable state during the quenching process and the coolant cannot flow irregularly, the spring body 6 cannot be quenched by shaking in the coolant. Therefore, the oxide scale that falls off the spring body 6 will fall into the inside of the spring body 6. When the spring body 6 after quenching is lifted, the inside of the spring body 6 will also lift the oxide scale together. Therefore, after quenching is completed, the control motor III 204 makes the rotating tube 201 drive the rotating ring 206 and the cleaning rod 1061 to reciprocate, and then the cleaning rod 1061 in the horizontal direction drives the blade 205 to reciprocate, thereby stirring the quenching liquid, so that the quenching liquid cleans the spring body 6 and removes part of the oxide scale on the surface of the spring body 6.

[0051] During quenching, when the high-temperature spring body 6 is placed in the quenching liquid, the quenching liquid around the spring body 6 will be in a boiling state under a huge temperature difference, causing the quenching liquid to be stirred, affecting the mechanical properties of the spring body 6 after quenching. Therefore, the blades 205 are densely distributed, and when the high-temperature spring body 6 is placed in the quenching liquid, the blades 205 cover the liquid surface of the boiling quenching liquid, thereby reducing the degree of stirring of the quenching liquid and improving the quenching efficiency.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
