Description

Technical Field

[0001] This invention relates to the field of rotor lamination processing technology, and in particular to a servo motor rotor lamination processing and forming apparatus and method. Background Technology

[0002] Motor laminations are made by stamping 0.3mm silicon steel sheets into laminations of different specifications to suit the stators and rotors of motors with different power. They have a wide range of applications. The motor rotor of a servo motor is also a rotating part of the motor. It is a device used to convert electrical energy into mechanical energy and mechanical energy into electrical energy.

[0003] In some existing rotor lamination processing devices, silicon steel sheets are stamped directly by a stamping block. When the stamping block comes into contact with the silicon steel sheet, it is prone to displacement due to external force, which can easily affect the stamping and forming effect of the silicon steel sheet. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] Therefore, the technical problem to be solved by the present invention is that some existing rotor lamination processing devices directly press silicon steel sheets through a pressing block when pressing them. When the pressing block comes into contact with the silicon steel sheet, it is easy for the position to shift under the action of external force, which can easily affect the stamping and forming effect of the silicon steel sheet.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a servo motor rotor lamination processing and forming device, including a stamping mechanism, which includes a processing table, a stamping groove is provided on the top surface of the processing table, a support frame is fixedly provided on the top surface of the processing table, a telescopic rod is fixedly provided on the bottom surface of the support frame, a stamping block is fixedly provided on the extended end of the telescopic rod, and guide components are provided at both the left and right ends of the processing table;

[0008] The positioning mechanism includes a piston box fixedly installed at the bottom of the processing table. The top of the piston box has a through hole facing downwards. The through hole is located below the stamping groove and is coaxial with the stamping groove. Several connecting rods are arranged in a rectangular pattern on the outer wall of the stamping block. The lower end of the connecting rods passes through the processing table, inserts into the piston box, and is fixedly installed with a piston plate. A first magnetic ring is fixedly installed on the inner side of the piston plate. The piston plate is movably installed in the piston box. Two adsorption tubes are symmetrically arranged on the top of the piston box. The upper ends of the two adsorption tubes are fixedly inserted into the bottom surface of the processing table, and the upper ends of the adsorption tubes are flush with the top surface of the processing table.

[0009] The feeding mechanism includes a piston cylinder fixedly inserted into the bottom surface of the processing table. Two reciprocating screws are rotatably arranged inside the piston cylinder. The lower ends of the two reciprocating screws are connected to an external spiral groove rod through a one-way bearing. A top material rod is inserted downward from the top of the processing table. The lower end of the top material rod passes through the processing table and is inserted into the piston cylinder, where a piston plate is fixedly installed. The piston plate is movably arranged inside the piston cylinder and threaded onto the reciprocating screws. A second magnetic ring is movably arranged on the inner wall of the through hole. The second magnetic ring attracts the first magnetic ring and moves up and down with the piston plate. A driving component is fixedly arranged inside the second magnetic ring. The driving component is movably sleeved on the external spiral groove rod. A discharge groove is opened on the side of the processing table away from the support frame.

[0010] Based on the above technical features: First, the silicon steel sheet is conveyed to the stamping groove and the stamping block through the guide component. Then, the stamping block is pushed down by the telescopic rod to stamp the silicon steel sheet. When the stamping block moves down, it drives the connecting rod and the piston plate to move down. At this time, the air pressure in the cavity at the top of the piston box decreases, and the silicon steel sheet is adsorbed through the adsorption tube. As the stamping block moves down, the pressing rod presses the silicon steel sheet, thereby reducing the possibility of the silicon steel sheet shifting position during stamping.

[0011] In a preferred embodiment of the servo motor rotor lamination forming device of the present invention, both ends of the stamping block are provided with cylinders, and a pressing rod is movably arranged inside the cylinder. The upper end of the pressing rod is inserted into the cylinder and connected to the cylinder by a spring.

[0012] Based on the above technical features: when the stamping block moves down, it causes the pressing rod to press the silicon steel sheet, thereby reducing the possibility of the silicon steel sheet shifting position during stamping.

[0013] As a preferred embodiment of the servo motor rotor lamination forming device of the present invention, the guide component includes two vertical plates and two guide rollers. The two ends of the two guide rollers are respectively rotatably inserted into the opposite side of the two vertical plates. The lower ends of the two vertical plates are fixedly connected to the processing table. One of the two guide components is the feeding end and the other is the discharging end.

[0014] Based on the above technical features: the two vertical plates facilitate the assembly of the guide rollers, and the rotation of the two guide rollers facilitates the conveying of silicon steel sheets, thereby conveying the silicon steel sheets to the stamping groove and stamping block for stamping and forming.

[0015] In a preferred embodiment of the servo motor rotor lamination forming device of the present invention, a fixed plate is fixedly installed on the two upright plates of the feeding end, a movable rod is vertically inserted into the top of the fixed plate, the lower end of the movable rod passes through the fixed plate and is fixedly installed with a scraper, a tension spring is fixedly sleeved on the movable rod, and the lower end of the tension spring is fixedly connected to the top surface of the fixed plate.

[0016] Based on the above technical features: when the silicon steel sheet passes through the guide component, the scraper facilitates the cleaning of impurities on the surface of the silicon steel sheet, thereby reducing the possibility that impurities on the surface of the silicon steel sheet will affect the stamping effect of the silicon steel sheet.

[0017] In a preferred embodiment of the servo motor rotor lamination forming device of the present invention, the discharge trough is inclinedly opened on the side of the processing table away from the support frame, and a collection box is provided on the side of the processing table away from the support frame, and the collection box is attached to the lower end of the discharge trough.

[0018] Based on the above technical features: when the rotor laminations fall into the discharge trough, they slide down rapidly and are then collected by the collection box.

[0019] In a preferred embodiment of the servo motor rotor lamination forming device of the present invention, an air jet pipe is fixedly provided on the top of the piston cylinder, and the upper end of the air jet pipe passes through the processing table and is flush with the top surface of the processing table.

[0020] Based on the above technical features: when the reciprocating screw rotates, the piston disc drives the top rod to move upward, and the top rod facilitates pushing one end of the rotor lamination up and down, thereby causing the rotor lamination to slide towards the discharge trough. At the same time, when the piston disc moves upward, the airflow in the piston cylinder is sprayed onto the bottom of the rotor lamination through the jet pipe, thereby increasing the conveying speed of the rotor lamination.

[0021] In a preferred embodiment of the servo motor rotor lamination forming device of the present invention, the outer wall of the second magnetic ring is provided with a plurality of balls along the circumference, and the inner wall of the through hole is provided with a number of vertical grooves corresponding to the number of balls along the circumference, and the balls slide in contact with the inner wall of the vertical grooves.

[0022] Based on the above technical features: the vertical groove and the ball bearings facilitate the limiting of the second magnetic ring, and the ball bearings reduce the resistance when the second magnetic ring moves, thereby enabling the second magnetic ring to move synchronously with the first magnetic ring when the piston plate drives the first magnetic ring to move.

[0023] In a preferred embodiment of the servo motor rotor lamination forming device of the present invention, the one-way bearing is fixedly inserted into the bottom of the reciprocating lead screw, the upper end of the outer helical groove rod passes through the piston cylinder and is inserted into the one-way bearing, and the outer helical groove rod is connected to the reciprocating lead screw through the one-way bearing.

[0024] Based on the above technical features: when the piston plate drives the first magnetic ring to move down, the second magnetic ring drives the driving component to move synchronously, and the driving component drives the outer spiral groove rod to rotate. At this time, the inner ring of the one-way bearing rotates while the outer ring remains stationary, thereby causing the reciprocating screw to remain stationary and making the piston plate and the ejector rod remain stationary.

[0025] As a preferred embodiment of the servo motor rotor lamination forming device of the present invention, the driving component includes a connecting rod and a ring. One end of the connecting rod is fixedly connected to a second magnetic ring, and the other end of the connecting rod is fixedly connected to the ring. The ring is movably sleeved on the outer spiral groove rod. A semi-circular block is fixedly provided on the inner side of the ring, and the semi-circular block slides in cooperation with the inner wall of the spiral groove of the outer spiral groove rod.

[0026] Based on the above technical features: when the second magnetic ring moves, it drives the connecting rod and the ring to move synchronously. At this time, the semicircular block slides along the inner wall of the spiral groove of the outer spiral rod, thereby causing the outer spiral rod to rotate.

[0027] Another technical solution proposed by this invention: a method for processing and forming a servo motor rotor lamination, comprising the following steps:

[0028] S101: First, the silicon steel sheet is conveyed to the stamping groove and the stamping block through the guide at the feeding end. Then, the stamping block is pushed down by the telescopic rod to stamp the silicon steel sheet.

[0029] S102: When the stamping block moves down, it drives the connecting rod and piston plate to move down. At this time, the air pressure in the top cavity of the piston box decreases and the silicon steel sheet is adsorbed through the adsorption tube. As the stamping block moves down, the pressing rod presses the silicon steel sheet, thereby reducing the possibility of the silicon steel sheet shifting position during stamping.

[0030] S103: When the piston plate drives the first magnetic ring to move down, the second magnetic ring drives the driving component to move synchronously. The driving component drives the outer spiral groove rod to rotate. At this time, the inner ring of the one-way bearing rotates while the outer ring remains stationary, thereby causing the reciprocating screw to remain stationary and keeping the piston plate and the ejector rod stationary.

[0031] S104: After the silicon steel sheet is stamped, the telescopic rod pulls the stamping block and the connecting rod upward. At this time, the connecting rod drives the piston plate to move upward and restores the air pressure in the top cavity of the piston box, thereby causing the adsorption tube to lose its adsorption function and the silicon steel sheet to lose its limit.

[0032] S105: When the piston plate drives the first magnetic ring to move upward, the second magnetic ring drives the driving component to move synchronously. The driving component drives the outer spiral groove rod to rotate. At this time, the outer ring of the one-way bearing rotates synchronously with the inner ring, thereby causing the reciprocating screw to rotate with the outer ring of the one-way bearing, and causing the piston plate to drive the top rod to move upward, thereby pushing the stamped rotor lamination upward and causing the rotor lamination to slide towards the discharge groove, thereby realizing the automatic unloading of the rotor lamination. As the reciprocating screw rotates, the piston plate drives the top rod to reset, thus facilitating the subsequent stamping of silicon steel sheets.

[0033] S106: After the rotor laminations are blanked, the stamped silicon steel sheets are conveyed through the guide at the discharge end, and then the silicon steel sheets are wound up by the winding mechanism.

[0034] In summary, the present invention has at least one of the following beneficial effects:

[0035] 1. When the stamping block moves down, it drives the connecting rod and piston plate to move down. At this time, the air pressure in the top cavity of the piston box decreases and the silicon steel sheet is adsorbed through the adsorption tube. As the stamping block moves down, the pressing rod presses the silicon steel sheet, thereby reducing the possibility of the silicon steel sheet shifting position during stamping.

[0036] 2. When the reciprocating screw rotates, the piston disc drives the top rod to move upward. The top rod facilitates the movement of one end of the rotor lamination up and down, thereby causing the rotor lamination to slide towards the discharge slot. At the same time, when the piston disc moves upward, the airflow in the piston cylinder is sprayed onto the bottom of the rotor lamination through the jet pipe, thereby pushing the rotor lamination into the discharge slot. Therefore, it is more convenient for the rotor lamination to discharge. Attached Figure Description

[0050] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0052] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0053] Example 1, referring to Figure 1-9 This is the first embodiment of the present invention. This embodiment provides a servo motor rotor lamination processing and forming device, including a stamping mechanism 100, which includes a processing table 101. The top surface of the processing table 101 is provided with a stamping groove 102. A support frame 103 is fixedly provided on the top surface of the processing table 101. A telescopic rod 104 is fixedly provided on the bottom surface of the support frame 103. A stamping block 105 is fixedly provided at the extended end of the telescopic rod 104. The telescopic rod 104 pushes the stamping block 105 down to stamp the silicon steel sheet and cooperates with the stamping groove 102 to stamp the silicon steel sheet into a rotor lamination.

[0054] Both ends of the stamping block 105 are provided with cylinders 105a. A pressing rod 105b is movably arranged inside the cylinder 105a. The upper end of the pressing rod 105b is inserted into the cylinder 105a and connected to the cylinder 105a by a spring 105c. When the stamping block 105 moves down, it causes the pressing rod 105b to press the silicon steel sheet, thereby reducing the possibility of the silicon steel sheet shifting during stamping. As the stamping block 105 continues to move down, the pressing rod 105b continuously extends into the cylinder 105a and causes the spring 105c to compress and deform. When the stamping block 105 moves up, the pressing rod 105b loses pressure. At this time, the spring 105c pushes the pressing rod 105b to reset.

[0055] The processing table 101 is provided with guide components 106 at both ends. The guide components 106 include two vertical plates 106a and two guide rollers 106b. The two ends of the two guide rollers 106b are respectively rotatably inserted into the opposite side of the two vertical plates 106a. The lower ends of the two vertical plates 106a are fixedly connected to the processing table 101. One of the two guide components 106 is the feeding end and the other is the discharging end. The two vertical plates 106a cooperate to facilitate the assembly of the guide rollers 106b. The two guide rollers 106b rotate to facilitate the conveying of silicon steel sheets, thereby conveying the silicon steel sheets to the stamping groove 102 and the stamping block 105 for stamping and forming.

[0056] Fixed plates 106c are fixedly installed on the two vertical plates 106a at the feeding end. A movable rod 106d is vertically inserted into the top of the fixed plate 106c. The lower end of the movable rod 106d passes through the fixed plate 106c and is fixedly installed with a scraper 106e. A tension spring 106f is fixedly sleeved on the movable rod 106d. The lower end of the tension spring 106f is fixedly connected to the top surface of the fixed plate 106c. When the silicon steel sheet passes through the guide 106, the scraper 106e facilitates the cleaning of impurities on the surface of the silicon steel sheet, thereby reducing the possibility that impurities on the surface of the silicon steel sheet will affect the stamping effect of the silicon steel sheet. The tension spring 106f pulls the movable rod 106d and the scraper 106e downward, thereby ensuring that the scraper 106e is always in contact with the surface of the silicon steel sheet.

[0057] The positioning mechanism 200 includes a piston box 201 fixedly installed at the bottom of the processing table 101. The top of the piston box 201 has a through hole 202 facing downward. The through hole 202 is located below the stamping groove 102 and is coaxially arranged with the stamping groove 102. The waste material in the stamping groove 102 can be discharged through the through hole 202.

[0058] The outer wall of the stamping block 105 is provided with several connecting rods 203 arranged in a rectangular shape. The lower end of the connecting rod 203 passes through the processing table 101, is inserted into the piston box 201, and is fixedly provided with a piston plate 204. The inner side of the piston plate 204 is fixedly provided with a first magnetic ring 205. The piston plate 204 is movably arranged in the piston box 201. When the stamping block 105 moves, it drives the connecting rods 203 and the piston plate 204 to move synchronously.

[0059] Two adsorption tubes 206 are symmetrically arranged on the top of the piston box 201. The upper ends of the two adsorption tubes 206 are fixedly inserted into the bottom surface of the processing table 101. The upper ends of the adsorption tubes 206 are flush with the top surface of the processing table 101. When the stamping block 105 moves down, it drives the connecting rod 203 and the piston plate 204 to move down. At this time, the air pressure in the cavity at the top of the piston box 201 decreases, and the silicon steel sheet is adsorbed through the adsorption tubes 206. As the stamping block 105 moves down, the pressing rod 105b presses the silicon steel sheet, thereby reducing the possibility of the silicon steel sheet shifting during stamping.

[0060] The feeding mechanism 300 includes a piston cylinder 301 fixedly inserted into the bottom surface of the processing table 101. Two reciprocating screws 302 are rotatably arranged inside the piston cylinder 301. The lower ends of the two reciprocating screws 302 are connected to an outer spiral grooved rod 304 through a one-way bearing 303. The one-way bearing 303 is a type of bearing that can rotate freely in one direction and is locked in the other direction. When the outer spiral grooved rod 304 rotates, the inner ring of the one-way bearing 303 rotates while the outer ring remains stationary, thereby causing the reciprocating screws 302 to remain stationary and keeping the piston disc 306 and the ejector rod 305 stationary. When the outer spiral grooved rod 304 rotates in the opposite direction, the outer ring of the one-way bearing 303 rotates synchronously with the inner ring, thereby causing the reciprocating screws 302 to rotate with the outer ring of the one-way bearing 303.

[0061] A top feed rod 305 is inserted downwards into the top of the processing table 101. The lower end of the top feed rod 305 passes through the processing table 101 and is inserted into the piston cylinder 301, where a piston disc 306 is fixedly installed. The piston disc 306 is movably installed in the piston cylinder 301 and threaded onto the reciprocating screw 302. An air jet pipe 301a is fixedly installed at the top of the piston cylinder 301. The upper end of the air jet pipe 301a passes through the processing table 101 and is flush with the top surface of the processing table 101. When the reciprocating screw 302 rotates, the piston disc 306 drives the top feed rod 305 to move upwards. The top feed rod 305 facilitates pushing one end of the rotor lamination up and down, thereby causing the rotor lamination to slide towards the discharge groove 309. At the same time, when the piston disc 306 moves upwards, the airflow in the piston cylinder 301 is sprayed onto the bottom of the rotor lamination through the air jet pipe 301a, thereby increasing the conveying speed of the rotor lamination.

[0062] A second magnetic ring 307 is movably disposed on the inner wall of the through hole 202. The second magnetic ring 307 attracts the first magnetic ring 205 and moves up and down with the piston plate 204. A number of balls 307a are disposed on the outer wall of the second magnetic ring 307 along the circumference. A number of vertical grooves 202a corresponding to the number of balls 307a are opened on the inner wall of the through hole 202 along the circumference. The balls 307a slide in cooperation with the inner wall of the vertical grooves 202a. The cooperation between the vertical grooves 202a and the balls 307a facilitates the limiting of the second magnetic ring 307. The cooperation of the balls 307a reduces the resistance when the second magnetic ring 307 moves, thereby enabling the second magnetic ring 307 to move synchronously with the first magnetic ring 205 when the piston plate 204 drives the first magnetic ring 205 to move.

[0063] A driving component 308 is fixedly installed inside the second magnetic ring 307. The driving component 308 is movably sleeved on the outer spiral groove rod 304. The driving component 308 includes a connecting rod 308a and a ring 308b. One end of the connecting rod 308a is fixedly connected to the second magnetic ring 307, and the other end of the connecting rod 308a is fixedly connected to the ring 308b. The ring 308b is movably sleeved on the outer spiral groove rod 304. A semi-circular block 308c is fixedly installed on the inner side of the ring 308b. The semi-circular block 308c slides with the inner wall of the spiral groove of the outer spiral groove rod 304. When the second magnetic ring 307 moves, it drives the connecting rod 308a and the ring 308b to move synchronously. At this time, the semi-circular block 308c slides along the inner wall of the spiral groove of the outer spiral groove rod 304, thereby causing the outer spiral groove rod 304 to rotate.

[0064] A discharge trough 309 is provided on the side of the processing table 101 away from the support frame 103. The discharge trough 309 is inclined on the side of the processing table 101 away from the support frame 103. A collection box 309a is provided on the side of the processing table 101 away from the support frame 103. The collection box 309a is attached to the lower end of the discharge trough 309. When the rotor laminations fall into the discharge trough 309, they slide down quickly and are collected by the collection box 309a.

[0065] Furthermore, the one-way bearing 303 is fixedly inserted into the bottom of the reciprocating screw 302. The upper end of the outer spiral grooved rod 304 passes through the piston cylinder 301 and is inserted into the one-way bearing 303. The outer spiral grooved rod 304 and the reciprocating screw 302 are connected through the one-way bearing 303. When the piston plate 204 drives the first magnetic ring 205 to move down, the second magnetic ring 307 drives the driving member 308 to move synchronously. The driving member 308 drives the outer spiral grooved rod 304 to rotate. At this time, the inner ring of the one-way bearing 303 rotates while the outer ring remains stationary, thereby causing the reciprocating screw 302 to remain stationary and keeping the piston plate 306 and the ejector rod 305 stationary.

[0066] When the piston plate 204 drives the first magnetic ring 205 to move upward, the second magnetic ring 307 drives the drive component 308 to move synchronously. The drive component 308 drives the outer spiral groove rod 304 to rotate. At this time, the outer ring of the one-way bearing 303 rotates synchronously with the inner ring, thereby causing the reciprocating screw 302 to rotate with the outer ring of the one-way bearing 303. This causes the piston plate 306 to drive the ejector rod 305 to move upward, thereby pushing the stamped rotor lamination upward and causing the rotor lamination to slide towards the discharge groove 309, thus realizing the automatic unloading of the rotor lamination. As the reciprocating screw 302 rotates, the piston plate 306 drives the ejector rod 305 to reset, which facilitates the subsequent stamping of silicon steel sheets.

[0067] In summary, the silicon steel sheet is first conveyed to the stamping groove 102 and the stamping block 105 through the feed guide 106 at the feeding end. Then, the stamping block 105 is pushed down by the telescopic rod 104 to stamp the silicon steel sheet. When the stamping block 105 moves down, it drives the connecting rod 203 and the piston plate 204 to move down. At this time, the air pressure in the top cavity of the piston box 201 is reduced, and the silicon steel sheet is adsorbed through the adsorption tube 206. As the stamping block 105 moves down, the pressing rod 105b presses the silicon steel sheet, thereby reducing the possibility of the silicon steel sheet shifting position during stamping.

[0068] When the stamping block 105 moves down, it causes the connecting rod 203 and the piston plate 204 to move down. At this time, the air pressure in the top cavity of the piston box 201 decreases, and the silicon steel sheet is adsorbed through the adsorption tube 206. As the stamping block 105 moves down, the pressing rod 105b presses the silicon steel sheet.

[0069] When the piston plate 204 drives the first magnetic ring 205 to move upward, the second magnetic ring 307 drives the drive member 308 to move synchronously. The drive member 308 drives the outer spiral groove rod 304 to rotate. At this time, the outer ring of the one-way bearing 303 rotates synchronously with the inner ring, thereby causing the reciprocating screw 302 to rotate with the outer ring of the one-way bearing 303, and causing the piston plate 306 to drive the top rod 305 to move upward, thereby pushing the stamped rotor lamination upward and causing the rotor lamination to slide towards the discharge groove 309 for discharge.

[0070] Example 2: To better demonstrate an explosion-proof electric heating tube processing device, this example presents a method for processing and forming a servo motor rotor lamination, comprising the following steps:

[0071] Step 1: First, the silicon steel sheet is conveyed to the stamping groove 102 and the stamping block 105 through the guide 106 at the feeding end. Then, the stamping block 105 is pushed down by the telescopic rod 104 to stamp the silicon steel sheet.

[0072] Step 2: When the stamping block 105 moves down, it drives the connecting rod 203 and the piston plate 204 to move down. At this time, the air pressure in the top cavity of the piston box 201 decreases, and the silicon steel sheet is adsorbed through the adsorption tube 206. As the stamping block 105 moves down, the pressing rod 105b presses the silicon steel sheet, thereby reducing the possibility of the silicon steel sheet shifting position during stamping.

[0073] Step 3: When the piston plate 204 drives the first magnetic ring 205 to move down, the second magnetic ring 307 drives the drive component 308 to move synchronously. The drive component 308 drives the outer spiral groove rod 304 to rotate. At this time, the inner ring of the one-way bearing 303 rotates while the outer ring remains stationary, thereby causing the reciprocating screw 302 to remain stationary and keeping the piston plate 306 and the ejector rod 305 stationary.

[0074] Step 4: After the silicon steel sheet is stamped, the telescopic rod 104 pulls the stamping block 105 and the connecting rod 203 upward. At this time, the connecting rod 203 drives the piston plate 204 upward and restores the air pressure in the top cavity of the piston box 201, thereby causing the adsorption tube 206 to lose its adsorption function and the silicon steel sheet to lose its limit.

[0075] Step 5: When the piston plate 204 drives the first magnetic ring 205 to move upward, the second magnetic ring 307 drives the drive component 308 to move synchronously. The drive component 308 drives the outer spiral groove rod 304 to rotate. At this time, the outer ring of the one-way bearing 303 rotates synchronously with the inner ring, thereby causing the reciprocating screw 302 to rotate with the outer ring of the one-way bearing 303. This causes the piston plate 306 to drive the ejector rod 305 to move upward, thereby pushing the stamped rotor lamination upward and causing the rotor lamination to slide towards the discharge groove 309, thus realizing the automatic unloading of the rotor lamination. As the reciprocating screw 302 rotates, the piston plate 306 drives the ejector rod 305 to reset, which facilitates the subsequent stamping of silicon steel sheets.

[0076] Step 6: After the rotor laminations are blanked, the stamped silicon steel sheets are conveyed through the guide 106 at the discharge end, and then the silicon steel sheets are wound up by the winding mechanism.

6. A method for processing and forming a servo motor rotor lamination as described in any one of claims 1-5, comprising the following steps: S101: First, the silicon steel sheet is conveyed to the stamping groove (102) and the stamping block (105) through the guide (106) at the feeding end. Then, the stamping block (105) is pushed down by the telescopic rod (104) and the silicon steel sheet is stamped. S102: When the stamping block (105) moves down, it drives the connecting rod (203) and the piston plate (204) to move down. At this time, the air pressure in the top cavity of the piston box (201) decreases, and the silicon steel sheet is adsorbed through the adsorption tube (206). As the stamping block (105) moves down, the pressing rod (105b) presses the silicon steel sheet, thereby reducing the possibility of the silicon steel sheet shifting position during stamping. S103: When the piston plate (204) drives the first magnetic ring (205) to move down, the second magnetic ring (307) drives the drive component (308) to move synchronously. The drive component (308) drives the outer spiral groove rod (304) to rotate. At this time, the inner ring of the one-way bearing (303) rotates while the outer ring remains stationary, thereby causing the reciprocating screw (302) to remain stationary and making the piston plate (306) and the ejector rod (305) remain stationary. S104: After the silicon steel sheet is stamped, the telescopic rod (104) pulls the stamping block (105) and the connecting rod (203) upward. At this time, the connecting rod (203) drives the piston plate (204) upward and restores the air pressure in the top cavity of the piston box (201), thereby causing the adsorption tube (206) to lose its adsorption function and causing the silicon steel sheet to lose its limit. S105: When the piston plate (204) drives the first magnetic ring (205) to move upward, the second magnetic ring (307) drives the drive component (308) to move synchronously. The drive component (308) drives the outer spiral groove rod (304) to rotate. At this time, the outer ring of the one-way bearing (303) rotates synchronously with the inner ring, thereby causing the reciprocating screw (302) to rotate with the outer ring of the one-way bearing (303), and causing the piston plate (306) to drive the top rod (305) to move upward, thereby pushing the stamped rotor lamination upward and causing the rotor lamination to slide towards the discharge groove (309), thereby realizing the automatic unloading of the rotor lamination. As the reciprocating screw (302) rotates, the piston plate (306) drives the top rod (305) to reset, thus facilitating the subsequent stamping of silicon steel sheets. S106: After the rotor laminations are blanked, the stamped silicon steel sheets are conveyed through the guide (106) at the discharge end, and then the silicon steel sheets are wound up by the winding mechanism.
