Description

Technical Field

[0002] Motor rotor laminations are thin sheet parts made by stamping process, usually made of magnetic materials such as electrical steel. These laminations are stacked one by one to form the rotor core of the motor, which is an important path for the motor magnetic field.

[0003] At present, when producing motor rotor punching sheets, the operator usually manually places the ring blank into the punching die for punching and forming, which reduces the efficiency of rotor punching production.

[0004] Alternatively, for example, the invention with publication number CN118268445B discloses a motor rotor punching forming device, which, through the cooperation of a loading mechanism and a feeding mechanism, moves the motor rotor punching blanks stacked in a storage tank one by one in a circular manner to a lower mold plate for stamping, and performs a circular transfer on the stamped finished punching sheets and waste sheets to separate the finished punching sheets and waste sheets from the lower mold plate, thereby conveniently realizing automatic feeding and discharging during the stamping forming process of the motor rotor punching sheets.

[0005] When the feeding mechanism in the above scheme is feeding, it is mainly driven by the rotation of the first arc-shaped fixed ring and the second arc-shaped fixed ring, which drives the punching blank to move on the circular track plate, so that the motor rotor punching blank moves to the top of the lower mold plate. However, due to the lack of a positioning device in the device, the punching blank cannot be moved to the top of the lower mold plate during actual use. At this time, if the punching device punches the punching blank, it will cause deviations in the production of rotor punching and reduce the efficiency of punching production.

[0018] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 9 As shown, the present invention provides a punching device for producing and processing a motor rotor, comprising a support 1 and a circular ring blank 5, and further comprising: a punching assembly 2 and a feeding assembly 4, both of which are arranged on the support 1; a positioning assembly 6, which is arranged on the punching assembly 2 to assist in positioning the circular ring blank 5 and unloading the circular ring blank 5 after punching is completed; The punching assembly 2 includes a limit vertical rod 23 fixedly connected to the support 1, and a frame 21 is movably sleeved outside the limit vertical rod 23. A punch head 22 is fixedly installed at the bottom of the frame 21. A base 24 located directly below the punch head 22 is also fixedly installed at the bottom of the support 1. A track 25 is also fixedly connected to the support 1. The track 25 is located directly above the base 24, and a straight slot 251 is opened on the track 25. The feeding assembly 4 includes two sets of connecting rods 41 hinged on the top of the frame 21, and the connecting rod 41 is always in an inclined state. A push plate 43 is slidably provided on the inner side of the track 25, and a storage rack 44 is also fixedly connected to the track 25. The annular blank 5 is placed in the storage rack 44 and is located above the push plate 43. The gap between the storage rack 44 and the bottom of the track 25 is greater than the thickness of one annular blank 5 and less than the thickness of two annular blanks 5. A round rod 42 is movably connected inside the straight slot 251, and both ends of the round rod 42 pass through the straight slot 251 and one end of the round rod 42 is fixedly connected to the push plate 43, and the other end of the round rod 42 is movably sleeved on the bottom of the connecting rod 41; One end of the push plate 43 close to the round rod 42 is arc-shaped, and the arc-shaped part of the push plate 43 and one end of the track 25 close to the base 24 form an annular space for positioning the annular blank 5; A waste opening 12 is also provided at the bottom of the support 1, the top of the waste opening 12 is located directly below the base 24, and the bottom of the waste opening 12 is connected to the outside; A driving mechanism 3 for driving the frame 21 upward or downward is also installed on the top of the support 1; the driving mechanism 3 includes a motor 31 and a crankshaft 32 fixed to the top of the support 1, and a reduction gear set 34 is movably connected to the top of the motor 31, a connecting rod 33 is hinged on the eccentric shaft of the crankshaft 32, and the bottom end of the connecting rod 33 is hinged to the top of the frame 21, the output shaft of the motor 31 is drivingly connected to the input shaft of the reduction gear set 34, and the output end of the reduction gear set 34 is drivingly connected to the crankshaft 32; By adopting the above scheme, the frame 21 is driven downward by operating the driving mechanism 3, so that the punching head 22 punches the annular blank 5 on the track 25 and directly above the base 24 to form a punching sheet. When the frame 21 moves downward, it will also push the push plate 43 to move through the connecting rod 21 and the round rod 42, and make the push plate 43 move close to the arc end to the side of the storage rack 44 away from the support 1. At this time, the annular blank 5 in the storage rack 44 will fall onto the track 25. When the frame 21 is reset upward, the stamped annular blank 5 will be lifted up through the positioning assembly 6. At the same time, the connecting rod 21 will also drive the push plate 43 to reset through the round rod 42, and the reset of the push plate 43 will push the annular blank 5 at the bottom of the storage rack 44 to the part of the track 25 located above the base 24, thereby completing the loading, improving the loading efficiency and also playing a good positioning operation on the annular blank 5.

[0020] like Figure 1-Figure 6 As shown, when the circular ring blank 5 is located on the track 25 and directly above the base 24, a gap is left between the arc-shaped portion of the push plate 43 and the circular ring blank 5; an elastic top block 431 is elastically connected to one end of the push plate 43 close to the base 24; the push plate 43 can push the circular ring blank 5 directly above the base 24 through the elastic top block 431; A protrusion 221 is fixedly connected to the bottom of the punch head 22. The bottom of the protrusion 221 is conical and the diameter of the protrusion 221 is smaller than the hole diameter of the circular ring blank 5. By adopting the above scheme, when the boss 221 moves downward, the bevel block 11 will release the squeezing of the bevel block 2 63. At this time, the hook-shaped part at the bottom end of the rod 61 will move to the outside of the boss 221 under the action of the elastic force of the spring combination rod 1 62. When the boss 221 passes through the center of the annular blank 5, the bottom end of the rod 61 will squeeze the edge of the circular hole at the center of the annular blank 5, so that the annular blank 5 has a tendency to move toward the support 1 and fits more closely with the end of the track 25, thereby ensuring the stability of the punch head 22 when punching the annular blank 5. At the same time, it can ensure that the annular blank 5 is directly below the punch head 22 to ensure the accuracy of the device when punching the annular blank 5.

[0021] like Figure 1-Figure 6 As shown, the positioning assembly 6 includes a rod 61 movably connected to the frame 21, the bottom end of the rod 61 passes through the punch head 22 and extends to the inside of the boss 221, the bottom of the rod 61 is hook-shaped, the top of the rod 61 extends to the outside of the frame 21 and is fixedly connected to the inclined block 2 63, and the inside of the frame 21 is fixedly connected to a spring combination rod 1 62, the rod body part of the spring combination rod 1 62 passes through the rod 61, and the spring part of the spring combination rod 1 62 is used to support the rod 61 to have a tendency to move toward the support 1; The support 1 is also fixedly connected with an inclined block 11, and one end of the inclined block 11 close to the inclined block 63 is inclined. In the initial state, the inclined block 11 abuts against the inclined block 63 to retract the bottom end of the rod 61 into the protruding column 221; By adopting the above scheme, the bottom end of the rod 61 is driven downward by the boss 221 to pass through the center of the circular ring blank 5, and after the circular ring blank 5 is punched, when the frame 21 is reset, the hook-shaped part at the bottom end of the rod 61 will lift the punch through the center circular hole of the circular ring blank 5, and when the frame 21 moves up to the top, the inclined block 2 63 will be squeezed by the inclined block 1 11 to drive the rod 61 to move away from the inclined block 11, so that the bottom end of the rod 61 is retracted into the boss 221, and the punch will fall onto the inclined plate 71 at this time, thereby improving the discharge efficiency of the device.

[0022] like Figure 1 , Figure 2 , Figure 4 , Figure 8 and Fig. 9 The cam 72 is a spring loaded part of the second support 10, and the cam 73 is a spring loaded part of the second support 10. The cam 73 is a spring loaded part of the second support 10, and the cam 73 is a spring loaded part of the second support 10. The cam 73 is a spring loaded part of the second support 10, and the cam 73 is a spring loaded part of the second support 10. When the above scheme is adopted, the round rod 42 is moved by the downward movement of the frame 21, and the round rod 42 will release the squeezing of the tooth plate 73. At this time, the elastic force of the spring combination rod 2 72 will push the inclined plate 71 to move away from the storage rack 44. At the same time, the gear 2 76 drives the rotating rod 74 and the gear 1 75 to rotate through the tooth groove 711, so that the tooth plate 73 moves with the round rod 42, so as to avoid the situation that the punch head 22 will collide with the inclined plate 71 when it moves downward. When the frame 21 moves upward and resets, the round rod 42 will squeeze the tooth plate 73 to move, so that the inclined plate 71 is moved to the bottom of the punch head 22 through the cooperation of the rotating rod 74, gear 1 75, gear 2 76 and tooth groove 711, so as to facilitate the discharge operation of the punching sheet.

[0023] The working principle and use process of the present invention: First, the driving mechanism 3 is operated to drive the frame 21 and the punch head 22 downward, and the punch head 22 will punch the circular ring blank 5 on the track 25 and directly above the base 24 to form a punch, and the excess waste will be discharged through the holes on the base 24 and the track 25 and the waste opening 12. At the same time, when the frame 21 moves downward, it will push the push plate 43 to move through the connecting rod 21 and the round rod 42, and make the push plate 43 move close to the arc end to the side of the storage rack 44 away from the support 1. At this time, the circular ring blank 5 in the storage rack 44 will fall onto the track 25. When the frame 21 is reset upward, the positioning assembly 6 will be used to lift the stamped circular ring blank 5. At the same time, the connecting rod 21 will also drive the push plate 43 to reset through the round rod 42, and the reset of the push plate 43 will push the circular ring blank 5 at the bottom of the storage rack 44 to the part of the track 25 located above the base 24, thereby completing the loading. When the boss 221 moves downward, the inclined block 11 releases the squeezing of the inclined block 2 63. At this time, the hook-shaped portion at the bottom of the rod 61 moves to the outside of the boss 221 under the action of the elastic force of the spring combination rod 1 62. When the boss 221 passes through the center of the annular blank 5, the bottom of the rod 61 squeezes the edge of the circular hole at the center of the annular blank 5, so that the annular blank 5 has a tendency to move toward the support 1 and fits more closely with the end of the track 25, thereby ensuring the stability of the punch head 22 when punching the annular blank 5. When the bottom end of the rod 61 passes through the center of the circular ring blank 5, the punch head 22 starts to cut the circular ring blank 5. When the device is reset, the hook-shaped part at the bottom end of the rod 61 will lift the punch through the central circular hole of the circular ring blank 5. When the frame 21 moves up to the top, the inclined block 2 63 will be squeezed by the inclined block 1 11 to drive the rod 61 to move away from the inclined block 11, so that the bottom end of the rod 61 is retracted into the protruding column 221, and the punch will fall onto the inclined plate 71. When the frame 21 moves downward to move the round rod 42, the round rod 42 will release the squeeze on the tooth plate 73. At this time, the elastic force of the spring combination rod 2 72 will push the inclined plate 71 away from the storage rack 44. At the same time, the gear 2 76 drives the rotating rod 74 and the gear 1 75 to rotate through the tooth groove 711, so that the tooth plate 73 moves with the round rod 42 to avoid the situation where the punch head 22 collides with the inclined plate 71 when it moves downward. When the frame 21 moves upward to reset, the round rod 42 will squeeze the tooth plate 73 to move, so that the inclined plate 71 is moved to the bottom of the punch head 22 through the cooperation of the rotating rod 74, gear 1 75, gear 2 76 and tooth groove 711, so as to facilitate the discharge operation of the punching sheet.
