Description

Technical Field

[0001] This utility model relates to the field of punching equipment technology, and in particular to a punching equipment for processing automotive stamping parts. Background Technology

[0002] A punching machine is a mechanical device that, after the raw materials are installed, uses a power mechanism to drive the punching die to punch holes in the material. Punching machines can perform operations such as sheet metal processing, stamping, molding, and embossing to force metal into the die.

[0003] In the prior art, Chinese Patent No. CN220029455U discloses a punching and drilling equipment for processing automotive stamping parts. This equipment is beneficial for positioning parts and can more accurately determine the relative position between the drilling point and the reference hole, thereby improving the processing position accuracy at the drilling point. However, in practical applications, there are still many drilling positions required when processing automotive stamping parts. The stamping parts need to be limited before each drilling operation, and the limit needs to be removed after drilling. This operation is cumbersome and consumes a lot of operating time, resulting in low drilling efficiency. Therefore, we disclose a punching equipment for processing automotive stamping parts. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a punching equipment for processing automotive stamping parts, so as to solve the problem of low drilling efficiency.

[0005] To achieve the above objectives, this utility model provides a punching device for processing automotive stamping parts, comprising a drilling machine body, a punching hole in the middle of the drilling machine body, a punching cylinder fixedly connected to the top of the drilling machine body, a drilling rod fixedly connected to the output end of the punching cylinder, a material discharge hole in the middle of the drilling machine body, the drilling rod slidably connected to the material discharge hole, a push plate fixedly connected to the outer wall of the drilling rod, first springs and limiting rods fixedly connected to both sides of the top of the drilling machine body, a connecting plate fixedly connected to the upper ends of the two first springs, the push plate being located at the upper end of the connecting plate, the connecting plate and the limiting rod being movably sleeved, a plurality of sleeves fixedly connected to the lower end of the connecting plate, the sleeves being slidably connected to the drilling machine body, a positioning rod being movably sleeved to the lower end of the sleeves, a second spring fixedly connected to the top end of the positioning rod, the second spring being fixedly connected to the connecting plate, and the positioning rod being located inside the punching hole.

[0006] Preferably, the limiting rod has several holes in its middle, and screws are threaded into the holes, with the screws located at the upper end of the connecting plate.

[0007] Preferably, the connecting plate includes a circular ring plate and two rectangular plates, the two rectangular plates are fixedly connected to both sides of the circular ring plate, the drilling rod is located in the middle of the circular ring plate, the inner diameter of the circular ring plate is greater than the outer diameter of the drilling rod, and the diameter of the push plate is greater than the inner diameter of the connecting plate.

[0008] Preferably, the positioning rod is T-shaped and is distributed equidistantly around the drilling rod in a ring.

[0009] Preferably, a moving groove is provided at the lower end of the drilling machine body, and a limiting block and a material dropping box are slidably connected in the moving groove. The limiting block is fixedly connected to both ends of the material dropping box, and the material dropping box is located below the material dropping hole. A limiting plate is rotatably connected to one end of the drilling machine body, and the limiting plate is in contact with the outer wall of the material dropping box.

[0010] Preferably, the moving groove is a cross-shaped groove, the material box and the two limiting blocks form a cross shape, and the material discharge hole is located above one end of the material box.

[0011] Preferably, the bottom end of the material box is fixedly connected with a plurality of telescopic sleeve rods and a third spring, and the inner cavity of the material box is slidably connected with a buffer plate. The bottom end of the buffer plate is fixedly connected to the top end of the telescopic sleeve rods and the third spring, and the third spring is sleeved on the outside of the telescopic sleeve rods.

[0012] Preferably, the buffer plate is inclined relative to the horizontal plane, and the buffer plate is inclined upward towards the material discharge hole.

[0013] The beneficial effects of this utility model are as follows: When the drilling rod moves, it drives the push plate to move together. The drilling machine body restricts the movement position of the connecting plate through the first spring and the limiting rod, so that the connecting plate can move up and down along the limiting rod. The connecting plate fixes the position of the second spring and the sleeve, so that the connecting plate restricts the movement direction and distance of the positioning rod through the sleeve and the second spring. Thus, when the drilling rod moves downward, it drives the push plate to move downward, so that the push plate squeezes the connecting plate to move downward, and then the connecting plate pushes the second spring and the positioning rod to move downward, so that the positioning rod fits against the stamping part and restricts the position of the stamping part. This makes the position of the stamping part more stable when drilling. When the drilling rod continues to move downward to drill the stamping part, the push plate continues to move downward and squeezes the sleeve through the connecting plate, so that the sleeve compresses the second spring and squeezes the positioning rod, which strengthens the limiting effect of the positioning rod on the stamping part without damaging the positioning rod and the stamping part. It also eliminates the need for additional operations to restrict the position of the stamping part, reduces the operation steps when drilling the stamping part, and thus improves the drilling efficiency of the stamping part. The drilling machine body restricts the position of the limiting block and the material box through the moving groove, so that the material box can collect the debris generated after drilling, which facilitates the subsequent work of the workers.

[0019] like Figures 1-3As shown, a punching device for processing automotive stamping parts includes a drilling machine body 1. A punching hole 2 is formed in the middle of the drilling machine body 1. A punching cylinder 3 is fixedly connected to the top of the drilling machine body 1. A drilling rod 4 is fixedly connected to the output end of the punching cylinder 3. A material discharge hole 13 is formed in the middle of the drilling machine body 1. The drilling rod 4 is slidably connected within the material discharge hole 13. A push plate 5 is fixedly connected to the outer wall of the drilling rod 4. First springs 6 and limiting rods 8 are fixedly connected to both sides of the top of the drilling machine body 1. A connecting plate 7 is fixedly connected to the upper ends of the two first springs 6. The push plate 5 is located above the connecting plate 7. The connecting plate 7 and the limiting rods 8 are movably sleeved. A plurality of sleeves 10 are fixedly connected to the lower end of the connecting plate 7. The sleeves 10 are slidably connected to the drilling machine body 1. The lower ends of the sleeves 10 are movable. A positioning rod 11 is fitted, and a second spring 12 is fixedly connected to the top of the positioning rod 11. The second spring 12 is fixedly connected to the connecting plate 7. The positioning rod 11 is located inside the punching hole 2. Several holes are opened in the middle of the limiting rod 8, and screws 9 are threaded into the holes. The screws 9 are located at the upper end of the connecting plate 7. The connecting plate 7 includes a circular ring plate and two rectangular plates. The two rectangular plates are fixedly connected to the two sides of the circular ring plate respectively. The drilling rod 4 is located in the middle of the circular ring plate. The inner diameter of the circular ring plate is larger than the outer diameter of the drilling rod 4. The diameter of the push plate 5 is larger than the inner diameter of the connecting plate 7. The positioning rod 11 is T-shaped and is distributed equidistantly around the drilling rod 4 in a ring. In use, a punching cylinder 3 is fixedly connected to the top of the drilling machine body 1. The output end of the punching cylinder 3... A drilling rod 4 is fixedly connected to the drilling machine body 1, fixing the position of the stamping cylinder 3. This allows the stamping cylinder 3 to move the drilling rod 4. A material discharge hole 13 is provided in the middle of the drilling machine body 1, and the drilling rod 4 is slidably connected within the material discharge hole 13. A push plate 5 is fixedly connected to the outer wall of the drilling rod 4, restricting the movement of the drilling rod 4 through the material discharge hole 13. When the drilling rod 4 moves, it will move the push plate 5 together. First springs 6 and limiting rods 8 are fixedly connected to both sides of the top of the drilling machine body 1. A connecting plate 7 is fixedly connected to the upper end of the two first springs 6. The push plate 5 is located on the upper end of the connecting plate 7. The connecting plate 7 and the limiting rods 8 are movably sleeved, allowing the drilling machine body 1 to restrict the movement of the connecting plate 7 through the first springs 6 and the limiting rods 8. The position allows the connecting plate 7 to move up and down along the limiting rod 8. Several sleeves 10 are fixedly connected to the lower end of the connecting plate 7. The sleeves 10 are slidably connected to the drilling machine body 1. A positioning rod 11 is movably sleeved at the lower end of each sleeve 10. A second spring 12 is fixedly connected to the top of the positioning rod 11 and is fixedly connected to the connecting plate 7. The positioning rod 11 is located inside the punching hole 2, allowing the connecting plate 7 to fix the positions of the second spring 12 and the sleeves 10. This, in turn, restricts the movement direction and distance of the positioning rod 11 through the sleeves 10 and the second spring 12. Consequently, when the drilling rod 4 moves downward, it drives the push plate 5 downward, causing the push plate 5 to press the connecting plate 7 downward. This, in turn, causes the connecting plate 7 to push the second spring 12 and the positioning rod 11 downward.The positioning rod 11 is fitted to the stamping part to restrict its position, making the stamping part more stable during drilling. As the drilling rod 4 continues to move downward to drill the stamping part, the push plate 5 continues to move downward and squeezes the sleeve 10 through the connecting plate 7. This causes the sleeve 10 to compress the second spring 12 and squeeze the positioning rod 11, strengthening the limiting effect of the positioning rod 11 on the stamping part without damaging the positioning rod 11 or the stamping part. Furthermore, no additional operation is required to limit the position of the stamping part, reducing the number of steps involved in drilling the stamping part and thus improving the drilling efficiency. Several holes are provided in the middle of the limiting rod 8, and screws 9 are threaded into these holes. The screws 9 are located at the upper end of the connecting plate 7, so that the connection between the screws 9 and the limiting rod 8 restricts the connection plate 7. The position of the connecting plate 7 is adjusted to regulate its relative position to the drilling machine body 1, facilitating its use. The connecting plate 7 includes a circular ring plate and two rectangular plates, with the two rectangular plates fixedly connected to both sides of the circular ring plate. The drilling rod 4 is located in the middle of the circular ring plate. The inner diameter of the circular ring plate is larger than the outer diameter of the drilling rod 4, preventing interference between the drilling rod 4 and the connecting plate 7. The diameter of the push plate 5 is larger than the inner diameter of the connecting plate 7, allowing the push plate 5 to move the connecting plate 7. The positioning rod 11 is T-shaped and equidistantly distributed around the drilling rod 4, increasing the contact area between the positioning rod 11 and the stamping part, improving the limiting effect on the stamping part, and preventing the positioning rod 11 from contacting the drilling rod 4.

[0020] As a preferred embodiment of this example, Figure 2 and Figure 3As shown, a moving groove 14 is provided at the lower end of the drilling machine body 1. A limiting block 15 and a material drop box 16 are slidably connected in the moving groove 14. The limiting block 15 is fixedly connected to both ends of the material drop box 16. The material drop box 16 is located below the material drop hole 13. A limiting plate 17 is rotatably connected to one end of the drilling machine body 1. The limiting plate 17 is in contact with the outer wall of the material drop box 16. The moving groove 14 is a cross-shaped groove. The material drop box 16 and the two limiting blocks 15 form a cross shape. The material drop hole 13 is located above one end of the material drop box 16. Several telescopic sleeves 18 and a third spring 19 are fixedly connected to the bottom end of the material drop box 16. A buffer plate 20 is slidably connected to the inner cavity of the material drop box 16. The bottom of the buffer plate 20... The end is fixedly connected to the top of the telescopic sleeve 18 and the top of the third spring 19. The third spring 19 is sleeved on the outside of the telescopic sleeve 18. The buffer plate 20 is inclined relative to the horizontal plane and tilts upward towards the material drop hole 13. A moving groove 14 is opened at the lower end of the drilling machine body 1. A limit block 15 and a material drop box 16 are slidably connected in the moving groove 14. The limit block 15 is fixedly connected to both ends of the material drop box 16. The material drop box 16 is located below the material drop hole 13, so that the drilling machine body 1 restricts the position of the limit block 15 and the material drop box 16 through the moving groove 14, so that the material drop box 16 can collect the debris generated after drilling, which is convenient for the subsequent work of the workers. A limiting plate 17 is rotatably connected to one end of the drilling machine body 1. The limiting plate 17 fits against the outer wall of the discharge box 16, allowing the drilling machine body 1 to restrict the position of the discharge box 16 after connection with the drilling machine body 1 via the limiting plate 17. This makes the position of the discharge box 16 relatively stable and facilitates the loosening of the connection between the limiting plate 17 and the discharge box 16. The moving groove 14 is a cross-shaped groove, and the discharge box 16 and the two limiting blocks 15 form a cross shape, which makes the limiting effect of the moving groove 14 on the limiting blocks 15 and the discharge box 16 good. The discharge hole 13 is located above one end of the discharge box 16, so that the debris in the discharge hole 13 will fall into the discharge box 16. Several telescopic sleeves 18 and a third spring 19 are fixedly connected to the bottom of the 6. A buffer plate 20 is slidably connected to the inner cavity of the discharge box 16. The bottom end of the buffer plate 20 is fixedly connected to the top end of the telescopic sleeves 18 and the third spring 19. The third spring 19 is sleeved on the outside of the telescopic sleeves 18, so that larger pieces falling onto the top surface of the buffer plate 20 will squeeze the third spring 19, thereby absorbing part of the impact and reducing the possibility of damage to the buffer plate 20 and the discharge box 16. The buffer plate 20 is inclined relative to the horizontal plane and tilts upward towards the discharge hole 13 to prevent falling pieces and debris from accumulating at the lower end of the discharge hole 13.
