Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a high-precision automotive parts press. Background Technology

[0002] In the automotive manufacturing industry, presses are key equipment used to process various metal parts, and their processing accuracy directly affects the quality and consistency of the products.

[0003] Traditional automotive parts presses typically use hydraulic cylinders to drive the upper die downwards to complete the stamping operation. However, the press lacks effective buffering at the end of the stroke and during the return stroke, resulting in rigid impacts and vibrations between the upper die and the worktable or limiting device. This can adversely affect the overall structure of the press and the lifespan of the die. Furthermore, many existing buffering structures are fixed and cannot be adjusted according to different processing conditions, lacking process adaptability. To solve these problems, this utility model provides an automotive parts press with high processing precision. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision automotive parts press.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-precision automotive parts press includes a worktable. Support rods are fixedly connected to the four corners of the worktable's upper surface. A common top seat is fixedly connected to the upper ends of the four support rods. An installation groove is formed at the upper end of the top seat, and a hydraulic cylinder is fixedly installed inside the installation groove. An upper mold is fixedly connected to the telescopic end of the hydraulic cylinder. Connecting seats are fixedly connected to both sides of the upper mold. Connecting rods are fixedly connected to both sides of the two connecting seats. Limiting rods are fixedly connected to the four corners between the worktable and the top seat. Limiting grooves adapted to the limiting rods are formed at the other ends of the four connecting rods. A first buffer assembly is provided at the lower end of each of the four limiting rods, and a second buffer assembly is fixedly connected to the upper end of each of the four limiting rods.

[0006] As a further improvement of this utility model, the first buffer assembly includes a first lower collar sleeved on the lower end of the limiting rod, a first buffer spring fixedly connected to the upper end of the first lower collar, a second lower collar fixedly connected to the upper end of the first buffer spring, and both the first buffer spring and the second lower collar sleeved on the surface of the limiting rod.

[0007] As a further improvement of this utility model, a mounting block is fixedly connected to one side of the first lower collar. A threaded hole is provided at the upper end of the mounting block. An adjusting bolt is threadedly connected inside the threaded hole. The lower end of the adjusting bolt is rotatably connected to the worktable through a bearing. A knob is fixedly connected to the upper end of the adjusting bolt.

[0008] As a further improvement of this utility model, the second buffer assembly includes a top block fixedly connected to the upper end of the limiting rod, a second buffer spring fixedly connected to the lower end of the top block, an upper collar fixedly connected to the lower end of the second buffer spring, and both the second buffer spring and the upper collar are sleeved on the surface of the limiting rod.

[0009] As a further improvement of this utility model, a lower mold is fixedly connected to the upper surface of the workbench, and positioning grooves are provided at the four corners of the upper surface of the lower mold. Positioning pins that are compatible with the positioning grooves are fixedly connected to the four corners of the lower surface of the upper mold.

[0010] As a further improvement of this utility model, the lower end of the workbench is fixedly connected to a base, and a scale is provided on the lower end of one side of each of the four support rods.

[0011] The beneficial effects of this utility model are: By incorporating a buffer assembly, when the upper mold descends and approaches the end of its stroke, the first buffer spring effectively absorbs impact energy, reducing vibration and noise caused by rigid collisions. The height of the first buffer spring can be flexibly adjusted via adjusting bolts to adapt to different processing requirements and working conditions. When the upper mold returns upwards, the second buffer spring cushions the impact upon reaching its final position. This dual buffering mechanism not only protects the mold and equipment structure and extends their service life but also makes the equipment run more smoothly, reducing the frequency of maintenance and parts replacement.

[0012] By setting locating pins, during use, the locating pins at the four corners of the lower surface of the upper mold and the locating grooves at the four corners of the upper surface of the lower mold precisely match, ensuring that the upper mold fits accurately with the lower mold during pressure processing. This effectively avoids processing errors caused by mold position deviations, allowing the dimensions and shapes of each part of the automotive parts to be shaped strictly according to design requirements during the molding process. This improves the processing accuracy of automotive parts and ensures the consistency and stability of product quality. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3 A high-precision automotive parts press includes a worktable 1. Support rods 2 are fixedly connected to the four corners of the upper surface of the worktable 1. The upper ends of the four support rods 2 are fixedly connected to the same top seat 3. The upper end of the top seat 3 has an installation groove. A hydraulic cylinder 4 is fixedly installed inside the installation groove. An upper mold 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4. Connecting seats 6 are fixedly connected to both sides of the upper mold 5. Connecting rods 7 are fixedly connected to both sides of the two connecting seats 6. Limiting rods 8 are fixedly connected to the four corners between the worktable 1 and the top seat 3. Limiting grooves 23 that are adapted to the limiting rods 8 are opened at the other ends of the four connecting rods 7. A first buffer assembly is provided at the lower end of the four limiting rods 8. A second buffer assembly is fixedly connected to the upper end of the four limiting rods 8.

[0019] In this utility model, the first buffer assembly includes a first lower collar 9 sleeved on the lower end of the limiting rod 8. A first buffer spring 10 is fixedly connected to the upper end of the first lower collar 9. The first buffer spring 10 can undergo elastic deformation when subjected to pressure, thereby playing a role in buffering and shock absorption. A second lower collar 11 is fixedly connected to the upper end of the first buffer spring 10. Both the first buffer spring 10 and the second lower collar 11 are sleeved on the surface of the limiting rod 8. This sleeved connection method enables the entire buffer structure to move stably along the limiting rod 8 without deviation.

[0020] A mounting block 12 is fixedly connected to one side of the first lower collar 9. The upper end of the mounting block 12 has a threaded hole, and an adjusting bolt 13 is threaded inside the threaded hole. The lower end of the adjusting bolt 13 is rotatably connected to the worktable 1 through a bearing. The adjusting bolt 13 can be rotated to change its position relative to the mounting block 12, thereby adjusting the buffer height. A knob 14 is fixedly connected to the upper end of the adjusting bolt 13. The surface of the knob 14 is provided with anti-slip texture, which is convenient for the operator to manually rotate and adjust.

[0021] The second buffer assembly includes a top block 15 fixedly connected to the upper end of the limiting rod 8. A second buffer spring 16 is fixedly connected to the lower end of the top block 15. An upper collar 17 is fixedly connected to the lower end of the second buffer spring 16. The second buffer spring 16 can provide buffering force when the upper mold 5 returns. Both the second buffer spring 16 and the upper collar 17 are sleeved on the surface of the limiting rod 8, ensuring the stability and accuracy of the second buffer assembly during the movement process.

[0022] The upper surface of the workbench 1 is fixedly connected to the lower mold 18. The four corners of the upper surface of the lower mold 18 are provided with positioning grooves 19. The four corners of the lower surface of the upper mold 5 are fixedly connected with positioning pins 20 that are compatible with the positioning grooves 19. The size and shape of the positioning grooves 19 are compatible with the positioning pins 20, which can ensure the precise positioning of the upper mold 5 and the lower mold 18. The lower end of the workbench 1 is fixedly connected to the base 21. The lower end of one side of the four support rods 2 is provided with a scale 22. The scale of the scale 22 is clear and accurate, which makes it convenient for the operator to observe the distance parameters of the first buffer component.

[0023] When this utility model is in use, the starting cylinder 4 drives its telescopic end to move the upper mold 5 downward. The connecting rod 7, which is fixed to the upper mold 5, slides downward along the limiting rod 8. The limiting groove 23 on the connecting rod 7 cooperates with the limiting rod 8 to ensure smooth movement. When the upper mold 5 moves downward, the connecting rod 7 will compress the first buffer component located at the lower end of the limiting rod 8. The first buffer spring 10 is compressed to buffer the downward impact. If it is necessary to adjust the buffering force of the first buffer spring 10, the adjusting bolt 13 in the threaded hole on the mounting block 12 on one side of the first lower collar 9 can be rotated. The lower end of the adjusting bolt 13 is rotatably connected to the worktable 1 through the bearing, and the upper end has a knob 14. Rotating the knob 14 will drive the adjusting bolt 13 to rotate, thereby adjusting the height of the first lower collar 9, and thus adjusting the height of the first buffer spring 10, changing its buffering effect. When the upper mold 5 completes processing and moves upward back, the connecting rod 7 will contact and compress the second buffer component located at the upper end of the limiting rod 8. The second buffer spring 16 is compressed to buffer the return impact. During this process, the positioning pin 20 fixed to the upper mold 5 and the positioning groove 19 fixed to the lower mold 18 on the worktable 1 precisely cooperate to ensure the mold closing accuracy. The scale 22 on the support rod 2 can be used to assist in observing the position.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
