Description
Technical Field
[0001] This utility model relates to the technical field of stator and rotor processing equipment, specifically to stamping equipment for amorphous ultrathin stators and rotors. Background Technology
[0002] Amorphous alloys have become ideal materials for manufacturing high-efficiency motor stators and rotors due to their excellent soft magnetic properties, such as extremely high magnetic permeability and low iron loss. However, amorphous ribbons are extremely thin (typically only about 25 μm thick), brittle and hard, and have minute unevenness on their surface.
[0003] Existing stamping equipment primarily focuses on improving stamping speed and accuracy, but generally lacks the function of online cleaning of amorphous strips before stamping. This results in contaminants on the strip surface being directly pressed into the die cavity during the stamping process, which not only affects the core dimensional accuracy and stacking coefficient of the stator and rotor plates, but more seriously, these hard impurities can cause wear or chipping of the precision die cutting edges, significantly shortening the die life.
[0004] Therefore, we proposed a stamping equipment for amorphous ultrathin stators and rotors to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this invention is to provide a stamping equipment for amorphous ultrathin stators and rotors to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A stamping equipment for amorphous ultrathin stators and rotors includes a high-speed punch press body. A processing table is fixedly installed on one side of the high-speed punch press body. A cleaning component is provided on the top of the processing table near one side. A connecting plate is provided on the top of the processing table near the middle position. A shaped frame is provided on the top of the connecting plate near one side.

The rear end of the rotating shaft moves through the rear side of the inner cavity of the shaped frame. A support roller is fixedly sleeved at the middle position of the outer circumference of the rotating shaft. A leveling component is provided on the top of the processing table near the other side. The cleaning assembly includes an active bevel gear fixedly installed at the rear end of the rotating shaft. A driven bevel gear meshes with the bottom of the active bevel gear. A vertical rod is fixedly installed at the bottom of the driven bevel gear, and the bottom end of the vertical rod is rotatably connected to the top of the processing table. An eccentric wheel is fixedly sleeved on the outer periphery of the vertical rod near the bottom end. A movable block is provided on the other side of the eccentric wheel. A bladder is fixedly installed on the other side of the movable block, and a vertical plate is fixedly installed on the other side of the bladder. The bottom of the vertical plate is fixedly connected to the processing table, and a cleaning frame is fixedly installed on the top of the processing table near the other side.
[0007] Preferably, a support frame is rotatably connected to the outer periphery of the upright near the bottom end, and the bottom of the support frame is fixedly connected to the processing table.
[0008] Preferably, a reset telescopic rod is fixedly installed on the other side of the movable block near both the front and rear sides, and the other end of the reset telescopic rod is fixedly connected to the upright plate. A reset spring is movably sleeved on the outer periphery of the reset telescopic rod, and the two ends of the reset spring are fixedly connected to the upright plate and the movable block, respectively.
[0009] Preferably, an air inlet pipe is inserted into the top of the bladder near one side, and an exhaust pipe is inserted into the top of the bladder near the other side. A flexible hose is fixedly installed at the top of the exhaust pipe, and the end of the flexible hose is fixedly connected to the cleaning frame.
[0010] Preferably, an intake check valve is provided on the outer periphery of the intake pipe, and an exhaust check valve is provided on the outer periphery of the exhaust pipe.
[0011] Preferably, the leveling assembly includes a straight plate fixedly installed on the top of the processing table near the other side. A straightening roller A is rotatably connected to the opposite side of the inner cavity of the straight plate. A fixing frame is fixedly installed on the outer periphery of the straight plate. Two connecting telescopic rods are fixedly installed at the top of the inner cavity of the fixing frame near the middle position. An n-shaped plate is fixedly installed at the bottom end of the connecting telescopic rods. A straightening roller B is rotatably connected to the opposite side of the inner cavity of the n-shaped plate.
[0012] Preferably, a connecting spring is movably sleeved on the outer periphery of the connecting telescopic rod, and the top and bottom ends of the connecting spring are fixedly connected to the fixing frame and the n-shaped plate, respectively.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. When stamping silicon steel sheets, the cleaning components work together to continuously compress the bladder, allowing gas to be delivered through the hose to the inner cavity of the cleaning frame to clean impurities on the surface of the silicon steel sheets. This prevents impurities from entering the mold and affecting the stamping effect of the stator.
[0014] 2. After cleaning the silicon steel sheet, the leveling assembly, connecting spring and connecting telescopic rod are used together to level the silicon steel sheet with the straightening roller B and the fixed frame. This makes the feeding positioning accurate and the stamping force uniform. This not only greatly reduces the punching burrs and ensures the consistency of the stator and rotor stamping dimensions, but also effectively avoids mold jamming and misfeeding caused by uneven sheet material, thereby protecting expensive molds and extending their service life.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0021] Please see Figure 1-4 A stamping equipment for amorphous ultrathin stators and rotors includes a high-speed press body 1 (the high-speed press body 1 is existing technology, and its working principle will not be described here). A processing table 2 is fixedly installed on one side of the high-speed press body 1. A cleaning component 5 is provided on the top of the processing table 2 near one side. A connecting plate 3 is provided on the top of the processing table 2 near the middle position. A shaped frame 4 is provided on the top of the connecting plate 3 near one side. A rotating shaft 8 is rotatably connected to the front side of the inner cavity of the shaped frame 4. The rear end of the rotating shaft 8 moves through the rear side of the inner cavity of the shaped frame 4. A support roller 7 is fixedly sleeved at the middle position of the outer periphery of the rotating shaft 8. A leveling component 6 is provided on the top of the processing table 2 near the other side. The cleaning component 5 includes a driving bevel gear 51 fixedly installed at the rear end of the rotating shaft 8. A driven bevel gear 52 meshes with the bottom of the driving bevel gear 51. A vertical rod 53 is fixedly installed at the bottom of the driven bevel gear 52, and the bottom end of the vertical rod 53 is rotatably connected to the top of the processing table 2. An eccentric wheel 54 is fixedly sleeved on the outer periphery of the vertical rod 53 near the bottom end. A movable block 55 is provided on the other side of the eccentric wheel 54. A bladder 57 is fixedly installed on the other side of the movable block 55, and a vertical plate 56 is fixedly installed on the other side of the bladder 57. The bottom of the vertical plate 56 is fixedly connected to the processing table 2. A cleaning frame 58 is fixedly installed on the top of the processing table 2 near the other side.
[0022] Specifically, when stamping silicon steel sheets, the cleaning component 5 continuously squeezes the bladder 57, allowing gas to be delivered through the hose 573 into the inner cavity of the cleaning frame 58 to clean impurities on the surface of the silicon steel sheets. This prevents impurities from entering the mold and affecting the stamping effect of the stator.
[0023] A support frame 531 is rotatably connected to the outer periphery of the upright 53 near the bottom end, and the bottom of the support frame 531 is fixedly connected to the processing table 2.
[0024] Specifically, by setting up the support frame 531, the rigidity and rotational stability of the upright 53 are effectively enhanced, preventing the upright 53 from shaking or bending due to gear meshing force and centrifugal force of eccentric wheel 54, ensuring transmission accuracy and long-term reliability of the entire cleaning assembly 5, and reducing maintenance requirements.
[0025] On the other side of the movable block 55, near the front and rear sides, a reset telescopic rod 551 is fixedly installed, and the other end of the reset telescopic rod 551 is fixedly connected to the upright plate 56. A reset spring 552 is movably sleeved on the outer periphery of the reset telescopic rod 551, and the two ends of the reset spring 552 are fixedly connected to the upright plate 56 and the movable block 55, respectively.
[0026] Specifically, when the protruding part of the eccentric wheel 54 pushes the movable block 55 to squeeze the bladder 57, the movable block 55 can be quickly and automatically pulled back to its initial position under the elastic force of the return spring 552, preparing for the next squeezing. This ensures that the bladder 57 can efficiently and rhythmically complete the inhalation-exhalation cycle, generating a continuous and stable pulse airflow, and has a simple structure and rapid response.
[0027] An air inlet pipe 571 is inserted into the top of the bladder 57 near one side, and an exhaust pipe 572 is inserted into the top of the bladder 57 near the other side. A hose 573 is fixedly installed at the top of the exhaust pipe 572, and the end of the hose 573 is fixedly connected to the cleaning frame 58.
[0028] Specifically, when the bladder 57 is compressed, the internal air pressure increases, the inlet one-way valve closes, and the exhaust one-way valve opens. The high-pressure airflow is then sprayed onto the material surface inside the cleaning frame 58 through the exhaust pipe 572 and the hose 573. When the bladder 57 returns to its original position, a negative pressure is created inside, the exhaust one-way valve closes, and the inlet one-way valve opens, drawing in fresh air. This design achieves directional, oil-free, and dry cleaning airflow, effectively blowing away dust and debris from the surface of the amorphous ribbon while avoiding scratches that might occur to the ultra-thin and fragile amorphous surface when using contact cleaning tools (such as brushes).
[0029] An intake check valve is provided on the outer periphery of the intake pipe 571, and an exhaust check valve is provided on the outer periphery of the exhaust pipe 572. Example 2
[0030] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 2 and Figure 4 The leveling assembly 6 includes a straight plate 61 fixedly installed on the top of the processing table 2 near the other side. A straightening roller A63 is rotatably connected to the opposite side of the inner cavity of the straight plate 61. A fixing frame 62 is fixedly installed on the outer periphery of the straight plate 61. Two connecting telescopic rods 66 are fixedly installed at the top of the inner cavity of the fixing frame 62 near the middle position. An n-shaped plate 64 is fixedly installed at the bottom end of the connecting telescopic rods 66. A straightening roller B65 is rotatably connected to the opposite side of the inner cavity of the n-shaped plate 64.
[0031] Specifically, after cleaning the silicon steel sheet, with the cooperation of the leveling component 6, the connecting spring 661 and the connecting telescopic rod 66, the straightening roller B65 and the fixing frame 62 level the silicon steel sheet, making the feeding positioning accurate and the stamping force uniform. This not only greatly reduces the punching burrs and ensures the consistency of the stator and rotor stamping dimensions, but also effectively avoids mold jamming and misfeeding caused by uneven sheet metal, thereby protecting expensive molds and extending their service life.
[0032] Connecting springs 661 are movably sleeved on the outer periphery of the connecting telescopic rod 66, and the top and bottom ends of the connecting springs 661 are fixedly connected to the fixing frame 62 and the n-shaped plate 64, respectively.
[0033] Specifically, the pressure of the connecting spring 661 can adapt to the minute thickness fluctuations of the amorphous ribbon, achieving smooth flattening and avoiding damage to the ultra-thin material caused by rigid compression.
[0034] In use, the silicon steel sheet is first placed on top of the support roller 7 and passed through the inner cavity of the cleaning frame 58, ensuring it is positioned appropriately within the high-speed punch press body 1. During continuous punching, the movement of the silicon steel sheet causes the support roller 7 to rotate, which in turn drives the rotating shaft 8 fixed within the inner cavity of the support roller 7 to rotate. As the rotating shaft 8 rotates, the driving bevel gear 51 fixed at its end also rotates, driving the driven bevel gear 52 meshing with it to rotate. The eccentric wheel 54, sleeved on the outer circumference of the rod 53, rotates via the upright rod 53 fixed to the bottom of the driven bevel gear 52. When the eccentric wheel 54 rotates, the movable block 55 reciprocates under the coordinated action of the return telescopic rod 551 and the return spring 552. The reciprocating movement of the movable block 55 continuously compresses the bladder 57 and delivers gas to the inner cavity of the cleaning frame 58 through the hose 573, thereby cleaning the top and bottom of the silicon steel sheet and preventing impurities from entering the mold and affecting the stator punching effect.
[0035] During the movement of the silicon steel sheet, the connecting spring 661 and the connecting telescopic rod 66 work together to level the silicon steel sheet using the straightening roller B65 and the fixing frame 62, ensuring accurate feeding positioning and uniform stamping force. This not only significantly reduces punching burrs and ensures the consistency of the dimensional accuracy of the stator and rotor laminations, but also effectively avoids mold jamming and misfeeding problems caused by uneven sheet metal, thereby protecting the expensive molds and extending their service life.
