Description

Technical Field

[0001] This utility model relates to the field of continuous stamping die technology, specifically a continuous stamping die for an automotive ball end cap. Background Technology

[0002] In the automotive manufacturing industry, the ball joint plug is a key component, and its production quality and efficiency directly affect the performance and manufacturing cost of the entire vehicle.

[0003] Traditional mold designs often lack effective buffering mechanisms to handle the enormous impact forces generated during stamping. This makes the mold and workpiece susceptible to damage during stamping, reducing the mold's service life and increasing the risk of workpiece deformation or damage. Summary of the Invention

[0004] The purpose of this utility model is to provide a continuous stamping die for an automotive ball joint plug, in order to solve the problem mentioned in the background art that traditional die designs often lack an effective buffering mechanism for the huge impact force generated during the stamping process. This leads to the die and workpiece being easily damaged during the stamping process, reducing the service life of the die, and increasing the risk of workpiece deformation or damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous stamping die for an automotive ball joint plug, comprising a base, a lower die seat fixedly installed at the center of the top of the base, supporting outer rods fixedly connected to the four sides of the top of the base, lifting plates slidably connected to the top positions of the four supporting outer rods, a stamping seat fixedly connected to the center of the bottom of the lifting plates, outer plates fixedly connected to both sides of the lower die seat, a buffer groove 1 opened at the two sides of the top of the lower die seat, and a sliding groove 1 opened on both sides of the lower die seat corresponding to the buffer groove 1. A buffer plate is provided at the top of the buffer groove. A buffer spring is fixedly connected to the outer side of the bottom of the buffer plate. The bottom of the buffer spring is fixedly connected to the bottom of the buffer groove. A buffer groove is provided at the center of the top of the outer plate. Three buffer plates are provided inside the buffer groove. Buffer springs are fixedly connected between the three buffer plates. The buffer spring at the bottom of the buffer plate is fixedly connected to the bottom of the buffer groove. External pressure rods are fixedly connected to both sides of the stamping seat, corresponding to the top of the two buffer plates.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] The continuous stamping die for this automotive ball joint plug effectively absorbs the vertical impact force generated during stamping by creating a buffer groove on the top of the lower die base and installing a buffer plate and a buffer spring. The buffer plate, under the action of the buffer spring, can move flexibly up and down, thus reducing the direct impact of the stamping block on the lower die base and protecting the die structure from damage. The sliding plates on both sides of the buffer plate slide within the sliding groove, ensuring the stability of the buffer plate when absorbing impact and preventing shaking or displacement caused by impact, further enhancing the overall structural stability of the die. Three layers of buffer plates and buffer springs are installed in the buffer groove on the top of the outer plate, forming a multi-layered buffer structure. This design not only effectively disperses... The horizontal impact force can be further reduced by the interaction between the two buffer plates, thus protecting the workpiece from excessive compression or deformation. The abutment is set at the bottom center of the buffer groove, and its top passes through the buffer plate and corresponds to the abutment groove at the bottom of the stamping seat. During the stamping process, the abutment can further disperse the impact force and transfer some of the impact energy to the stamping seat through the abutment groove, thereby reducing the pressure on the lower die seat and extending the service life of the die. The buffer plate and buffer spring are set in the buffer groove three opened at the bottom of the stamping seat, providing an additional buffer layer for the die. This design allows the die to adapt to the stamping requirements of workpieces of different materials, thicknesses or shapes, improving the versatility and flexibility of the die.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a continuous stamping die for an automotive ball joint plug, including a base 1, a lower die base 2 fixedly installed at the center of the top of the base 1, support rods 3 fixedly connected to the four sides of the top of the base 1, lifting plates 4 slidably connected to the top positions of the four support rods 3, a stamping seat 5 fixedly connected to the center of the bottom of the lifting plate 4, outer plates 8 fixedly connected to both sides of the lower die base 2, buffer grooves 10 are provided on both sides of the top of the lower die base 2, and sliding grooves 11 are provided on both sides of the buffer grooves 10 inside the lower die base 2, with a top of the buffer grooves 10... There is a buffer plate 12, and a buffer spring 15 is fixedly connected to the outer side of the bottom of the buffer plate 12. The bottom of the buffer spring 15 is fixedly connected to the bottom of the buffer groove 10. A buffer groove 2 16 is opened in the center of the top of the outer plate 8. Three buffer plates 2 18 are arranged inside the buffer groove 2 16. Buffer springs 2 21 are fixedly connected between the three buffer plates 2 18. The buffer springs 2 21 at the bottom of the buffer plate 2 18 are fixedly connected to the bottom of the buffer groove 2 16. External pressure rods 9 are fixedly connected to both sides of the stamping seat 5, corresponding to the top of the two buffer plates 2 18.

[0015] Both sides of the buffer plate 12 are fixedly connected to the slide plate 13. The side of the slide plate 13 away from the buffer plate 12 extends into the interior of the slide groove 11 and is slidably connected to the inner wall of the slide groove 11.

[0016] The bottom of the stamping base 5 is provided with buffer grooves 22 on both sides. The bottom of the buffer grooves 22 is slidably connected to a buffer plate 24. The top of the buffer plate 24 is fixedly connected to a buffer spring 25. The top of the buffer spring 25 is fixedly connected to the top of the buffer groove 22.

[0017] The bottom of the stamping seat 5 has a raised section on both sides, which corresponds to the center of the bottom of the buffer groove 22. The bottom of the buffer groove 23 extends to the outside of the stamping seat 5. The center of the bottom of the buffer groove 10 is fixedly connected to a push rod 14. The top of the push rod 14 extends to the outside of the buffer plate 12. The push rod 14 is located directly below the buffer groove 23.

[0018] The inner sides of the outer plate 8 are provided with sliding grooves 17 on both sides of the buffer groove 16. The two sides of the buffer plate 18 are fixedly connected with sliding plates 19. The side of the sliding plate 19 away from the buffer plate 18 extends into the interior of the sliding groove 17 and is slidably connected to the sliding groove 17.

[0019] The slide 217 has a fixed internal connection of a support rod 20, which is fitted and slidably connected to three slide plates 219.

[0020] A top plate 6 is fixedly connected to the top of the four supporting outer rods 3. A cylinder 7 is fixedly connected to the center of the top of the top plate 6. The output end of the cylinder 7 extends through to the outside of the top plate 6 and is fixedly connected to the top of the lifting plate 4.

[0021] Working principle: Cylinder 7 starts, and its output end pushes the lifting plate 4 downward, causing the stamping seat 5 to move downward. The outer pressure rod 9 descends with the stamping seat 5, gradually approaching the second buffer plate 18, but not yet making contact. As the stamping seat 5 continues to descend, the protrusion at its bottom first contacts the abutment rod 14. The abutment rod 14 pushes the first buffer plate 12 to slide downward in the first buffer groove 10, compressing the first buffer spring 15. At the same time, the sliding plates 13 on both sides of the first buffer plate 12 slide in the first sliding groove 11, ensuring the smooth movement of the first buffer plate 12. As the stamping seat 5 descends further, the outer pressure rod 9 finally contacts the second buffer plate 18, pushing the second buffer plate 18 to slide downward in the second buffer groove 16, compressing the second buffer spring 21. The sliding plates 19 on both sides of the second buffer plate 18 then slide downward in the second buffer groove 16. The slide plate 12 slides within the second groove 17, while the support rod 20 provides additional stability, ensuring that the second buffer plate 18 moves smoothly and orderly. When the stamping seat 5 reaches its lowest point, the protrusion at its bottom completely enters the abutment groove 23. At this time, the third buffer plate 24 is subjected to the pressure at the bottom of the stamping seat 5 within the third buffer groove 22, compressing the third buffer spring 25. The sliding connection of the third buffer plate 24 ensures the stability during the stamping process and further disperses the impact force. The cylinder 7 starts in the reverse direction, driving the lifting plate 4 and the stamping seat 5 to move upward and return to the initial position. The first buffer plate 12, the second buffer plate 18, and the third buffer plate 24 gradually return to their initial positions under the action of the first buffer spring 15, the second buffer spring 21, and the third buffer spring 25, respectively, in preparation for the next stamping.

[0022] In summary, the continuous stamping die for the automotive ball joint plug effectively absorbs the vertical impact force generated during stamping by opening a buffer groove 10 on the top of the lower die holder 2 and setting a buffer plate 12 and a buffer spring 15. The buffer plate 12, under the action of the buffer spring 15, can move flexibly up and down, thereby reducing the direct impact of the stamping seat 5 on the lower die holder 2 and protecting the die structure from damage. The sliding plates 13 on both sides of the buffer plate 12 slide within the sliding groove 11, ensuring the stability of the buffer plate 12 when absorbing impact and avoiding shaking or displacement caused by impact, further enhancing the overall structural stability of the die. Three layers of buffer plates 18 and buffer springs 21 are set in the buffer groove 16 opened on the top of the outer plate 8, forming a multi-layer buffer structure. This design not only... The impact force is effectively dispersed in the horizontal direction, and the impact speed is further reduced through the interaction between the buffer plates 18, thereby protecting the workpiece from excessive compression or deformation. The abutment rod 14 is set at the bottom center of the buffer groove 10, and its top passes through the buffer plate 12 and corresponds to the abutment groove 23 at the bottom of the stamping seat 5. During the stamping process, the abutment rod 14 can further disperse the impact force and transfer some of the impact energy to the stamping seat 5 through the abutment groove 23, thereby reducing the pressure on the lower die seat 2 and extending the service life of the die. The buffer plate 24 and the buffer spring 25 are set in the buffer groove 22 opened at the bottom of the stamping seat 5, providing an additional buffer layer for the die. This design allows the die to adapt to the stamping requirements of workpieces of different materials, thicknesses or shapes, improving the versatility and flexibility of the die.
