Technical Field

[0002] In simple terms, the brake disc of an electric vehicle is a round disc that rotates when the vehicle is moving. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the vehicle. The brake disc has a good braking effect and is easier to maintain than drum brakes. The brake disc is a very important component in the braking system. A good brake disc has stable braking, no noise, and no shaking. In the processing of electric brake discs, stamping equipment is usually required.

[0003] Stamping dies can be divided into blanking dies, forming dies, etc. During the use of blanking dies, the raw materials will be separated into products and waste. The waste needs to be separated, otherwise the waste will easily accumulate and block the blanking hole, which is not conducive to the falling of the waste, thus affecting the stamping process, product processing quality and processing efficiency. Summary of the invention

During the continuous stamping process, if the waste material does not have a good guidance and discharge channel, it is easy to accumulate inside the equipment. By feeding in the middle of the compression spring, the waste material can be discharged from the mold more smoothly under the action of the elastic force of the compression spring, reducing the interference of the waste accumulation on the normal operation of the equipment. At the same time, the compression spring can isolate the contact between the waste material and the key components of the equipment to a certain extent.

When the waste material is discharged from the middle of the compression spring, the structure of the compression spring enables the waste material to be subjected to elastic forces from all directions of the compression spring when passing through.

During the continuous stamping process, if the waste material does not have a good guide and discharge channel, it is easy to accumulate inside the equipment. By discharging the waste material through the middle of the compression spring 16, the waste material can be discharged from the mold more smoothly under the elastic force of the compression spring 16, thereby reducing the interference of the waste material accumulation on the normal operation of the equipment. At the same time, the compression spring 16 can isolate the contact between the waste material and the key parts of the equipment to a certain extent. The method of unloading the material in the middle of the compression spring 16 can effectively reduce such wear and tear, and reduce the maintenance and replacement costs of the equipment. The top of the compression spring 16 is fixedly connected with a fixing ring 19, and the top of the fixing ring 19 is provided with an inclined groove 111. The base 11 is provided with a square groove 15 inside the unloading hole 17. The material to be processed is placed in the middle of the top of the limit component 2, and the hydraulic cylinder 4 is connected to an external power supply to work. The hydraulic cylinder 4 drives the stamping component 3 to move downward, thereby stamping the material and punching holes. The scrap material after being pressed contacts and squeezes the top block 110 under the action of the stamping assembly 3. The top block 110 is forced to drive the slider 18 to move inside the square groove 15, so that the top block 110 moves toward the inner wall close to the feeding hole 17. The top block 110 is located inside the trapezoidal hole 28. At this time, the scrap material enters the inside of the fixing ring 19. At the same time, the top block 110 moves relative to the inclined groove 111 on the fixing ring 19 during the movement, so that the fixing ring 19 exerts force on the compression spring 16. The compression spring 16 is compressed and deformed under the force. The scrap material passes through the fixing ring 19 under the action of gravity. Entering the interior of the compression spring 16, when the waste is discharged from the middle of the compression spring 16, the structure of the compression spring 16 enables the waste to be subjected to elastic forces from all directions of the compression spring 16 when passing through. This elastic force can effectively prevent the waste from getting stuck during the discharge process. The elasticity of the compression spring 16 can play a certain guiding role.

A square hole 26 is provided on the inner wall of the circular ring 25, and the circular ring 25 is away from the side of the limiting cylinder 24. It is set to be inclined, and the material to be processed is placed inside the limiting cylinder 24. When the material is placed in the limiting cylinder 24, the inclined inner wall of the ring 25 can guide them to move to the middle of the bottom of the limiting cylinder 24, and the gravity of the material is used to achieve automatic positioning. This automatic positioning function reduces the time and effort of manual adjustment of the material position and improves production efficiency. There are multiple square holes 26, and multiple rings 25 are evenly distributed with the limiting cylinder 24 as the center. A trapezoidal hole 28 is opened in the middle of the top of the fixing plate 21, and a through hole 27 is opened in the middle of the top of the limiting cylinder 24.

A circular hole 32 is formed on the top of the movable plate 31, and the round rod 12 is located inside the circular hole 32. The circular holes 32 are symmetrically arranged at both ends of the movable plate 31. A frame 33 is fixedly connected to the side of the movable plate 31 away from the base 11. The top of the frame 33 is fixedly connected to the output end of the hydraulic cylinder 4. A connecting block 34 is fixedly connected to the bottom of the frame 33. A connecting plate 35 is fixedly connected to the bottom of the connecting block 34. A fixing rod 36 is fixedly connected to the bottom of the connecting plate 35. There are multiple fixing rods 36, and multiple fixing rods 36 are located at the corners of the connecting plate 35. A rotating cylinder 37 is fixedly connected to the outer side of the fixing rod 36. A ball 38 is rotatably connected to the outer wall of the rotating cylinder 37. When the hydraulic cylinder 4 is connected to an external power supply to work, the hydraulic cylinder 4 drives the connecting plate 35 and the fixing rod 36 at the bottom corner to move downward, so that the rotating cylinder 37 and the ball 38 are fixed in the fixed The circular groove 23 of the fixed cylinder 22 slides inside, and a high-precision guiding function can be achieved through the cooperation of the ball 38 and the fixed cylinder 22. During the stamping process, the up and down movement of the equipment requires extremely high accuracy. The ball 38 and the fixed cylinder 22 can control the upper and lower gaps within a very small range, thereby ensuring the dimensional accuracy and shape accuracy of the stamped parts. At the same time, during the rolling process of the ball 38, the contact point changes continuously, making the pressure distribution on the surfaces of the rotating cylinder 37 and the fixed cylinder 22 more uniform, avoiding local excessive wear, which helps to extend the service life of the rotating cylinder 37 and the fixed cylinder 22, and reduce the maintenance cost of the equipment and the frequency of replacing parts. There are multiple ball 38, and a truncated cone 310 is fixedly connected to the middle of the bottom of the connecting plate 35, and a pressure head 311 is fixedly connected to the bottom of the truncated cone 310.

Figures 8 to 11As shown, the positioning assembly 39 includes a positioning cylinder 392, which is slidably connected to the outer side of the round table 310, and the positioning cylinder 392 is sleeved on the outer side of the round table 310. The bottom of the positioning cylinder 392 is fixedly connected with a trapezoidal block 393, and a through groove 394 is provided on the outer side of the trapezoidal block 393. There are multiple through grooves 394, and the inner wall of the through groove 394 is slidably connected with a triangular block 395. The top of the triangular block 395 is fixedly connected with a slide rod 397. The hydraulic cylinder 4 moves downward when working. The hydraulic cylinder 4 drives the connecting block 34 and the connecting plate 35 to move downward through the frame 33. The connecting plate 35 drives the trapezoidal block 393 at the bottom to slide relative to the inner wall of the ring 25, which plays a guiding role. At this time, the triangular block 395 exerts a force on the edge of the material inside the ring 25 under the elastic force of the reset spring 396. Due to the effect of the material, the material is subjected to the vertical and horizontal forces, so that the triangular block 395 fixes the material, so that during the stamping process, the center of the material and the pressure head 311 are located in the same straight line. As the connecting plate 35 continues to move downward, the connecting plate 35 drives the round table 310 and the pressure head 311 downward to stamp the material. After the stamping is completed, the hydraulic cylinder 4 drives the stamping assembly 3 to reset, and the pressure head 311 moves upward with the round table 310. Under the action of the positioning cylinder 392's own gravity, the triangular block 395 continues to exert force on the material to prevent the material from moving with the pressure head 311. The sliding rod 397 passes through the trapezoidal block 393, and the top of the sliding rod 397 is fixedly connected to the connecting ring 391. The top of the triangular block 395 is fixedly connected to the reset spring 396, and the reset spring 396 is fixedly connected to the inner wall of the through groove 394.

[0044] A stamping process for processing electric vehicle brake discs includes the following steps:

[0045] S1. Place the materials into the limiting cylinder 24. The inclined inner wall of the ring 25 can guide them to move to the middle of the bottom of the limiting cylinder 24, and use the gravity of the materials to achieve automatic positioning;

[0046] S2, punching the material, the hydraulic cylinder 4 is connected to an external power supply to work, and the connecting plate 35 drives the round table 310 and the pressing head 311 to punch the material downward;

[0047] S3, waste material unloading, the waste material after punching enters the interior of the compression spring 16 through the fixing ring 19 under the action of the punching assembly 3, and then leaves the equipment through the compression spring 16;

[0048] S4, equipment reset. After the stamping is completed, the hydraulic cylinder 4 drives the stamping assembly 3 to reset. Under the action of the gravity of the positioning cylinder 392 itself, the triangular block 395 continues to exert force on the material to prevent the material from moving with the pressing head 311.

[0049] When in use, the material to be processed is placed in the middle of the top of the limiting assembly 2. When the material is placed in the limiting cylinder 24, the inclined inner wall of the ring 25 can guide it to move to the middle of the bottom of the limiting cylinder 24, and automatic positioning is achieved by using the gravity of the material.

[0050] The hydraulic cylinder 4 is connected to an external power supply to work, and the hydraulic cylinder 4 drives the connecting plate 35 and the fixed rod 36 at the bottom corner to move downward, so that the rotating cylinder 37 and the ball 38 slide inside the circular groove 23 of the fixed cylinder 22, and the connecting plate 35 drives the trapezoidal block 393 at the bottom to slide relative to the inner wall of the ring 25, playing a guiding role. At this time, the triangular block 395 exerts a force on the edge of the material inside the ring 25 under the elastic force of the reset spring 396, and the material is subjected to the component forces in the vertical and horizontal directions, so that the triangular block 395 fixes the material, so that during the stamping process, the center of the material is on the same straight line as the pressing head 311. As the connecting plate 35 continues to move downward, the connecting plate 35 drives the frustum 310 and the pressing head 311 downward to stamp the material.

[0051] The waste material after punching contacts and is squeezed between the top block 110 under the action of the stamping assembly 3. The top block 110 is forced to drive the slider 18 to move inside the square groove 15, so that the top block 110 moves toward the inner wall close to the discharge hole 17. The top block 110 is located inside the trapezoidal hole 28. At this time, the waste material enters the interior of the fixing ring 19. At the same time, the top block 110 moves relative to the inclined groove 111 on the fixing ring 19 during the movement, so that the fixing ring 19 exerts force on the compression spring 16. The compression spring 16 is compressed and deformed under the force. Under the action of gravity, the waste material passes through the fixing ring 19 into the interior of the compression spring 16. When the waste material is discharged from the middle of the compression spring 16, the structure of the compression spring 16 enables the waste material to be subjected to elastic forces from all directions of the compression spring 16 when passing through. This elastic force can effectively prevent the waste material from getting stuck during the discharge process, and the elasticity of the compression spring 16 can play a certain guiding role.

[0052] After the stamping is completed, the hydraulic cylinder 4 drives the stamping assembly 3 to reset, and the pressing head 311 moves upward with the round table 310. Under the action of the gravity of the positioning cylinder 392, the triangular block 395 continues to exert force on the material to prevent the material from moving with the pressing head 311.
