[0028] The lower die 3 is preferably a split lower die, that is, the lower die 3 is divided into a left lower die 21 and a right lower die 22, the left and right lower dies can be pulled apart by a driving mechanism, specifically, driving cylinders 23 are symmetrically arranged on both sides of the rack 1, the movable end of the driving cylinder 23 is connected with the lower die 3, guide rods 24 are arranged on the left lower die 21 and the right lower die 22 and matched with the rack 1, vertical plates 25 are symmetrically arranged on the rack 1 and can be penetrated by the guide rods 24, the cylinder body of the driving cylinder 23 is fixed on the vertical plate 25, and the driving cylinder 23 is connected with the PLC controller, initially, the left lower die 21 and the right lower die 22 are combined into a whole lower die 3, then the punch 2 is used to stamp the plate piece to make the plate piece into an iron core piece.

[0029] Symmetrical suction holes 4 for suctioning the iron core piece after stamping are arranged on the lower surface of the punch 2, that is, when the punch 2 is matched with the lower die 3 to stamp and form the iron core piece, the suction holes 4 on the punch 2 can suction the iron core piece, in order to make the surface of the punch 2 complete when matched with the lower die 3, a sliding rod 5 is arranged in the suction hole 4, the lower end of the sliding rod 5 is initially in contact with the lower surface of the punch 2, an extrusion block 101 is arranged on the upper end of the sliding rod 5, a guide table 102 is arranged in the suction hole 4, a first spring 12 is arranged between the extrusion block 101 and the guide table 102, the first spring 12 is sleeved on the sliding rod 5 and the two ends of the first spring 12 abut against the extrusion block 101 and the guide table 102 respectively, in order to limit the upper end of the extrusion block 101 and make the lower end of the sliding rod 5 in contact with the punch 2, a sliding pin 8 is arranged in the punch 2 and in contact with the extrusion block 101.

[0030] The slide pin 8 is connected with a piston rod 7, the punch 2 is provided with a suction cylinder 6 capable of sucking the suction hole 4, the piston rod 7 is provided with a piston 15 matched with the suction cylinder 6, that is, the suction of the suction hole 4 is realized by the sliding of the piston rod 7 to drive the piston 15 in the suction cylinder 6, so that the required negative pressure for adsorption is achieved in the suction hole 4, the punch 2 is provided with a suction pipeline 14 connected with the suction hole 4 and the suction cylinder 6, as shown in the figure, taking the left suction cylinder 6 as an example, when the piston 15 slides to the right, the left end cavity of the suction cylinder 6 is communicated with the lower end side wall of the suction hole 4 through the suction pipeline 14, so that the suction cylinder 6 can suck the suction hole 4. Figure 3

[0031] In order to make the suction hole 4 have adsorption space when adsorbing the iron core piece, the left end of the slide pin 8 is provided with a long slot 11, when the piston 15 slides to the right, the extrusion block 101 makes the sliding rod 5 lift upward through the reset force of the first spring 12 so that the extrusion block 101 falls into the long slot 11, at this time, the punch 2 lower end surface and the sliding rod 5 lower end surface have a certain space, at this time, the piston 15 continues to slide to the right to generate the negative pressure for adsorption in the suction hole 4 to adsorb the iron core piece, the upper end of the extrusion block 101 is provided with an arc transition surface, the both ends of the long slot 11 are provided with a round corner transition matched with the extrusion block 101, preferably, the suction cylinder 6 is fixedly arranged in the punch 2, the punch 2 is provided with a slide pin hole 18 matched with the slide pin 8, the shape of the slide pin 8 is preferably rectangular, and the slide pin hole 18 is a rectangular hole, so that the slide pin 8 is arranged on one side of the punch 2.

[0032] The slide pin 8, the piston rod 7 and the piston 15 are preferably integrally formed, the piston 15 is provided with a Y-shaped sealing ring on the outer edge matched with the suction cylinder 6, the punch 2 is provided with a driving rod 10 capable of driving the slide pin 8 to displace to the center of the punch 2, specifically, the punch 2 is provided with a hexagonal column 16, the inertia block 9 is slidably arranged on the hexagonal column 16, the driving rod 10 is fixedly arranged on the inertia block 9, the second spring 13 is arranged between the inertia block 9 and the punch 2, the second spring 13 is sleeved on the hexagonal column 16 and the two ends thereof abut against the inertia block 9 and the punch 2 respectively, the inertia block 9 is provided with a hexagonal hole 17 matched with the hexagonal column 16, that is, the inertia block 9 is arranged on the hexagonal column 16 in a guided manner, when the punch 2 is matched with the lower die 3 to perform stamping, after stamping, the inertia block 9 continues to compress the second spring 13 due to the inertia force, so that the driving rod 10 continues to displace downward, the displacement of the driving rod 10 extrudes the slide pin 8 to realize the displacement of the slide pin 8.

[0033] ​The lower end of the driving rod 10 is provided with a driving slope 20, which is inclined from top to bottom to the side away from the center of the punch 2. The side away from the center of the punch 2 of the sliding pin 8 is provided with an arc surface 19 matched with the driving slope 20. That is, the driving rod 10 is displaced downward by the inertia of the inertia block 9, so that the driving slope 20 can extrude the arc surface 19, thereby making the sliding pin 8 displace to the side close to the center of the punch 2. In summary, after the punch 2 cooperates with the lower die 3 to punch and form the iron core piece, the inertia block 9 continues to displace downward to extrude the sliding pin 8 by the driving rod 10, and then the sliding pin 8 slides to the side close to the center of the punch 2. The sliding rod 5 falls into the long slot 11 by the resetting force of the first spring 12, and the sliding pin 8 continues to slide to suck the iron core piece in contact with the lower end surface of the punch 2 by the piston rod 7 driving the piston 15. Thus, the iron core piece can be adsorbed, and then the iron core piece can be synchronously upwardly slid with the punch 2.

[0034] One end of the piston rod 7 is provided with the sliding pin 8, and the end close to the center of the punch 2 is provided with a magnetic suction block 43. The magnetic suction blocks 43 on the two sides of the symmetrically arranged piston rod 7 are preferably of different polarities. That is, when the piston rod 7 is driven, the two magnetic suction blocks 43 simultaneously slide to the side close to the center of the punch 2, and then the mutual attraction force is generated due to the different polarities, thereby making the piston rod 7 remain at the position after the punch 2 is punched, that is, the suction hole 4 is always adsorbed with the iron core piece after the punch 2 is punched.

[0035] The center of the rack 1 is provided with a through hole 31 for the iron core piece to pass through. The outer diameter of the through hole 31 is preferably greater than the outer diameter of the punch 2 and less than the outer diameter of the combined lower die 3. The through hole 31 is concentrically arranged with the punch 2. The lower side of the through hole 31 is provided with a collecting device for collecting the iron core piece adsorbed on the punch 2. Specifically, the collecting device includes a collecting frame 32 and a jacking air cylinder 33. The jacking air cylinder 33 and the driving air cylinder 23 are preferably connected with the PLC controller of the punch press. After the punching is completed, the punch 2 rises, and at the same time, the driving air cylinder 23 drives the left lower die 21 and the right lower die 22 to displace to the two sides, so that the through hole 31 is exposed. Then, the jacking air cylinder 33 of the collecting device jacks the collecting frame 32 to contact the iron core piece on the punch 2, thereby realizing the collection of the iron core piece.

[0036] The iron core piece is provided with a plurality of positioning holes 34. The positioning holes 34 are the existing iron core piece pin positioning holes. The collecting frame 32 is provided with positioning rods 35 matched in number with the positioning holes 34. The iron core piece can be sleeved on the positioning rods 35 through the positioning holes 34. The positioning rods 35 are fixedly arranged on the collecting frame 32. The upper end of the positioning rod 35 is slidably provided with a positioning pin 36. The positioning pin 36 is preferably a resilient pin. The outer edge of the positioning pin 36 is smaller than the outer edge of the positioning rod 35. During collection, the positioning pin 36 is first inserted into the positioning hole 34, and then abuts against the punch 2. The positioning pin 36 is compressed, and then the positioning rod 35 cooperates with the positioning hole 34.

[0037] The punch 2 is equipped with a reset pin 41 to reset the slidable piston rod 7. A third spring 42 is provided between the reset pin 41 and the punch 2. During punching, the reset pin 41 is pushed against by the third spring 42, thereby making its lower end face flush with the end face of the punch 2. Figure 3 As shown, the lower end of the reset pin 41 is provided with a reset cone surface 44 that cooperates with the magnetic block 43. The reset cone surface 44 is inclined from top to bottom outward. The reset cone surface 44 is preferably located below the magnetic block 43. When the magnetic blocks 43 on both sides move towards the center synchronously, the iron chip is attracted. When the reset pin 41 is pushed upward, the reset cone surface 44 contacts the magnetic block 43, causing the magnetic blocks 43 on both sides to slide away from the center of the punch 2, thereby resetting the sliding pin 8 and detaching the iron chip from the attraction hole 4.

[0038] The reset pin 41 is located at the center of the punch 2. The collection rack 32 is provided with a lifting rod 45 that cooperates with the reset pin 41. After the collection rack 32 rises, the lifting rod 45 lifts the reset pin 41 to reset the piston rod 7. The collection rack 32 is provided with a support rod 51. The lifting cylinder 33 is provided with a rod hole 52 that cooperates with the support rod 51. The bottom plate of the collection rack 32 has magnetic attraction. The collection rack 32 can be attracted to the lifting end of the lifting cylinder 33 by magnetic attraction and the cooperation of the support rod 51 with the lifting cylinder 33, which facilitates the replacement and installation of the collection rack 32.

[0039] The frame 1 is equipped with a linear module 53 that moves the lifting cylinder 33 outside the frame 1. The linear module 53 is connected to the PLC controller. When the collecting device collects multiple iron chips, that is, when the iron chips required for a motor core are collected on the collecting rack 32, the PLC controller drives the linear module 53 to move the lifting cylinder 33 outside the frame 1, so that the operator can pick up, put down and replace the collecting rack 32.

[0040] Using the above-described method for producing a high-efficiency motor core: Initially, the lower die 3 is in a merged state, that is, the lower left die 21 and the lower right die 22 are merged into a whole lower die cavity, and then the punch press is started to perform stamping.

[0041] After the punch 2 and the lower die 3 work together to press the iron chip into shape, the inertial block 9 continues to move downward to make the drive rod 10 squeeze the sliding pin 8. Then the sliding pin 8 slides closer to the center of the punch 2, and the sliding rod 5 falls into the long groove 11 first by the reset force of the first spring 12. The sliding pin 8 continues to slide, and the piston rod 7 drives the piston 15 to suck up the suction hole 4, thereby adsorbing the iron chip that is in contact with the lower end face of the punch 2.

[0042] Subsequently, the core piece and the punch 2 are synchronously slid upward, at the same time, the PLC controller controls the driving cylinder 23 to slide the left and right lower dies 21 and 22 to the two sides, at this time, the through hole 31 is exposed, in order to improve the production efficiency, the PLC controller can control the jacking cylinder 33 to jack up the collecting frame 32 upward while the left and right lower dies are sliding, after the jacking rod 45 rises with the collecting frame 32, the reset pin 41 is jacked up to reset the piston rod 7, so that the punch 2 loses the adsorption of the core piece, that is, the core piece falls into the positioning rod 35 through the positioning hole 34;

[0043] Further, the jacking cylinder 33 resets the collecting frame 32 to be below the through hole 31, the driving cylinder 23 resets to make the left and right lower dies recombine, and the next stamping is performed, when the number of the core pieces on the collecting frame 32 reaches the set number after multiple stamping and collecting, the PLC controller drives the linear module 53 to move the collecting frame 32 to the outside of the rack 1, so as to take down the collecting frame 32, and place the empty collecting frame on the jacking cylinder 33 to make the next core.

[0044] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the same; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by the equivalent ones; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
