Description

Technical Field

[0001] This utility model relates to the field of rotor lamination processing technology, specifically to a rotor lamination stamping die. Background Technology

[0002] Motor rotor laminations are key components in motor manufacturing. Motor rotor laminations are thin metal sheets made by stacking highly conductive materials (such as copper, aluminum, iron, silicon steel, etc.). Depending on their shape, motor rotor laminations are divided into circular laminations, fan-shaped laminations, magnetic pole laminations, etc. Rotor laminations generally need to be stamped using stamping equipment to process them, and heat dissipation grooves or mounting grooves are stamped on them.

[0003] In existing technologies, the stamping of motor rotor laminations is mostly carried out by operators sitting at the workstation of the stamping forming device, manually placing the lamination blanks onto the stamping die plate using tools. After each stamping, the finished laminations and scrap pieces are removed from the die plate. Because the whole process requires manual operation, the stamping efficiency of motor rotor laminations is low, and there are also certain safety hazards. Improper operation can easily lead to production accidents. Therefore, this utility model proposes a rotor lamination stamping die. Summary of the Invention

[0025] The present invention will now be further described with reference to the accompanying drawings.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0027] Please see Figures 1-2 An embodiment of this utility model provides a rotor lamination stamping die, including a machine body 1, on which a lower die holder 2 and an upper die holder 3 are provided. Preferably, the lower die holder 2 is fixed on the machine body 1, and the upper die holder 3 is movably disposed on the machine body 1. The upper die holder 3 can be driven to rise and fall by a driving device equipped on the machine body 1, thereby performing a stamping action. This is a distinguishing feature of the prior art of this utility model.

[0028] The distinguishing technical features of this utility model also include: a base 4, disposed on one side of the machine body 1, with an arc-shaped plate 5 fixed on the base 4 by a column, and two through holes 6 extending through the arc-shaped plate 5. The lower die base 2 corresponds to one of the through holes 6. Preferably, the included angle between the two through holes 6 (with the center of the arc-shaped plate 5) is 90 degrees. A storage cylinder 7 connected to the other through hole 6 is disposed on the arc-shaped plate 5. An electric push rod 8 is disposed at the bottom end of the storage cylinder 7. The piston end of the electric push rod 8 extends into the storage cylinder 7 and is fixed with a lifting plate 9. In the actual stamping process, the stamping blanks can be stacked and then placed in the storage cylinder 7. The electric push rod 8 performs work, and its piston end drives the lifting plate 9 to move, thereby lifting the stacked stamping blanks upward. One blank is lifted and protrudes from the top of the arc plate 5 at a time. Preferably, the lower die base 2 is located in one of the through holes 6, and the top of the lower die base 2 is flush with the arc plate 5. A shaft 10 is rotatably mounted on the base 4. Several rings 11 are fixed to the top of the shaft 10 by a support rod. Preferably, four rings 11 are upright. The rings 11 abut and overlap with the top of the arc plate 5. The inner diameter of the rings 11, the through hole 6, and the storage cylinder 7 is the same as the diameter of the circular stamping blank. A driving component 12 for intermittently rotating the shaft 10 is provided on the base 4. A receiving frame 13 is provided on the base 4. The receiving frame 13 is located below the notch of the arc plate 5. When processing the rotor stamping, a batch of stamping blanks are stacked and then placed in the storage cylinder 7, located at the top. On the lifting plate 9, in the initial state, the topmost blank is lower than the top surface of the arc plate 5. At this time, two of the rings 11 correspond one-to-one with two through holes 6. The electric push rod 8 performs work, and its piston end drives the lifting plate 9 to move upward, thereby pushing the topmost blank out of the through hole 6. At this time, the blank is just inside the ring 11. The drive component 12 drives the shaft 10 to rotate intermittently. To make the scheme more reasonable, it rotates intermittently at 90 degrees. When the shaft 10 stops rotating, the ring 11 just transfers the blank to the top of the lower die holder 2. At this time, the loading is completed. During the stop, the upper die holder 3 moves downward, thereby stamping the blank. After stamping, the upper die holder 3 moves upward and resets. At this time, the shaft 10 rotates again, thereby... The ring 11 transfers the stamped blank and the scrap generated during stamping. When it is transferred to the notch, the blank and scrap (the rotor blank is a disc, usually with several annularly distributed slots or holes punched on it. After stamping, the finished blank is still a plate. The slots or holes are separated by stamping and are scrap, which is the existing technology) fall into the receiving frame 13, thus completing the unloading. By setting two through holes 6, which correspond to the lower die base 2 and the storage cylinder 7 respectively, and the shaft 10 rotates intermittently, the alternating loading and unloading can be achieved with the cooperation of the four rings 11 and the arc plate 5, thereby improving the processing efficiency. At the same time, during loading and unloading, the worker's limbs do not need to be involved between the lower die base 2 and the upper die base 3, thereby improving the safety performance.

[0029] In this scheme, an arc-shaped plate 5 is set up, and through holes 6 are opened on the arc-shaped plate 5 corresponding to the lower die base 2 and the storage cylinder 7 respectively. The drive component 12 drives the shaft 10 to rotate intermittently. With the cooperation of the four rings 11 and the arc-shaped plate 5, stamping is performed during the intermittent stop period, and the loading and unloading are alternately realized, thereby improving the processing efficiency. At the same time, during the loading and unloading, the worker's limbs do not need to be involved between the lower die base 2 and the upper die base 3, thereby improving the safety performance.

[0030] like Figure 7 As shown, a partial structure of the drive component 12 of this utility model is disclosed. The drive component 12 includes a driven grooved wheel 1201 fixed on the shaft 10, a motor 1202 mounted on the base 4, and a transmission dial 1203 fixed on the output shaft of the motor 1202, which is in transmission cooperation with the driven grooved wheel 1201. Preferably, the driven grooved wheel 1201 includes a disc body, and the outer surface of the disc body is provided with a plurality of arc-shaped grooves and a plurality of dial slots. The number of arc-shaped grooves and dial slots is four and they are staggered. The transmission dial 1203 includes a notched disc, and the notch of the notched disc... A support plate is provided at the opening, and a lever that slides with the slot is provided on the support plate. When the motor 1202 does work, its output shaft drives the transmission dial 1203 to rotate. When the transmission dial 1203 rotates, the lever on it slides with the slot. After the transmission dial 1203 rotates one revolution, the driven groove wheel 1201 drives the shaft 10 to rotate ninety degrees, thereby realizing the effect of intermittent rotation. The pauses in the intermittent rotation process not only facilitate the stamping process, but also facilitate the electric push rod 8 to lift the single blank into the ring 11 for feeding.

[0031] like Figure 5 As shown, a further technical solution for the circular ring 11 of this utility model is disclosed. A rubber ring 14 is coaxially provided at the bottom end of the circular ring 11. In order to ensure that the circular ring 11 can be loaded, unloaded or transferred, the circular ring 11 overlaps with the arc plate 5. By setting the rubber ring 14, the rubber ring 14 overlaps and rubs with the arc plate 5, thereby reducing the wear on the circular ring 11.

[0032] like Figure 5 As shown, a further technical solution for the circular ring 11 of this utility model is disclosed. An annular groove 15 is provided at the bottom end of the circular ring 11. A rubber ring 14 is movably inserted into the annular groove 15. An anti-collision spring 16 is connected between the rubber ring 14 and the inner wall of the annular groove 15. By opening the annular groove 15, the rubber ring 14 is inserted into the annular groove 15, and the anti-collision spring 16 is provided. Under the elastic force of the anti-collision spring 16, the rubber ring 14 effectively contacts and overlaps with the arc plate 5 to ensure smooth transfer of the blank. Even if the rubber ring 14 is worn, the rubber ring 14 can adaptively compensate under the elastic force of the anti-collision spring 16 to ensure that it can be contacted and overlapped with the arc plate 5, thus ensuring the stability of loading, unloading and transfer.

[0033] like Figure 3 As shown, the present invention discloses a further technical solution for the storage cylinder 7. A through groove 17 is provided on one side of the storage cylinder 7. Since the stamping blank is adapted to the storage cylinder 7, preferably, the cross-section of the through groove 17 is arc-shaped and slightly larger than a semicircle. By opening the through groove 17, when initially placing the stamping blank, it is not necessary to put it in from the top, but to place the stacked blank from the side, thereby further improving the convenience of material release.

[0034] like Figure 3 As shown, a further technical solution for the storage cylinder 7 of this utility model is disclosed. A sliding groove 18 is provided on one side of the storage cylinder 7, and a slider 19 is slidably inserted in the sliding groove 18. A straightening strip 20 is provided on the slider 19. Preferably, the sliding groove 18 is an arc-shaped groove opened on the outer arc surface of the storage cylinder 7. The longitudinal section of both the sliding groove 18 and the slider 19 is constructed as T-shaped. The slider 19 can slide along the sliding groove 18, but cannot completely detach from the sliding groove 18. When placing the billet, the slider 19 is slid to one side, and after the stacked billet is placed in the storage cylinder 7 from the side, the slider 19 is slid back to its original position. The straightening strip 20 is used to straighten the stacked billet to ensure that the billet and the storage cylinder 7 are in a coaxial state to ensure the smoothness of feeding.

[0035] like Figure 1 and Figure 6 As shown, the present invention discloses a further technical solution for the receiving frame 13. The receiving frame 13 is provided with a partition 21, and one end of the arc plate 5 is connected to two arc rods 22. By providing a partition 21 in the receiving frame 13, it is used to divide the frame into two storage cavities. One cavity is used to store the stamped scrap and the other cavity is used to store the stamped blank. When the blank is stamped and moves in a circular motion within the ring 11, it will pass through the notch and slide onto the two arc rods 22. The scrap is smaller and will fall directly downwards into one of the cavities. The blank is larger and is blocked by the arc rods 22, preventing it from falling. It can only fall downwards after passing completely through the arc rods 22, thus achieving the function of classifying and storing blanks and scraps.

[0036] like Figure 6As shown, a further technical solution for the receiving frame 13 of this utility model is disclosed. A groove 23 is provided on one side of the arc plate 5. A vertical rod 24 is fixed in the groove 23. A movable plate 25 is slidably sleeved on the vertical rod 24. A return spring 26 sleeved on the vertical rod 24 is installed between the movable plate 25 and the inner wall of the groove 23. Two arc rods 22 are fixed on the movable plate 25. Several conical blocks 27 are arranged in an array on the arc rods 22. By sliding the movable plate 25, the arc rods 22 are fixed on the movable plate 25. Under the elastic force of the return spring 26, the conical blocks 27 slightly... Above the arc plate 5, when the ring 11 slides from the arc plate 5 onto the arc rod 22, the ring 11 will abut against the inclined surface of the conical block 27. Under the abutment of the inclined surface, the arc rod 22 and the movable plate 25 are forced to move downward, thereby causing the movable plate 25 to squeeze the return spring 26. When the ring 11 passes the conical block 27, the movable plate 25 is reset under the elastic force of the return spring 26, thereby forcing the arc rod 22 to reset upward. During its upward reset process, it will knock the ring 11 or the blank. Through the vibration force generated by the knocking, the scrap is forced to separate better from the blank, which facilitates the effective classification and storage of blanks and scraps.

[0037] The above embodiments are merely descriptions for clearly illustrating the present utility model, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and the obvious variations or modifications derived therefrom are still within the protection scope of the present utility model.
