Description

Technical Field

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

[0002] Automotive parts are various components required for automobile manufacturing, such as body panels, chassis brackets, and engine fasteners. They are the basic units that make up a car. Positioning is required during stamping because only by fixing the position of the workpiece can the shape, hole position, and other dimensions of each stamping be ensured to meet the strict tolerance requirements of automotive parts. At the same time, it can avoid errors caused by manual placement, ensure that the specifications of workpieces in the same batch are consistent, and facilitate subsequent assembly. In addition, it can prevent the workpiece from shifting during stamping, reducing the risk of mold damage and safety accidents.

[0003] Currently, most automotive parts stamping and positioning equipment uses pre-punched holes in the sheet metal to fit into positioning pins when placing the sheet metal, thus fixing the sheet metal. This method is only suitable for sheet metal with pre-punched holes, while sheet metal without pre-punched holes is difficult to fix, reducing the equipment's versatility. In addition, traditional equipment usually requires a separate buffer mechanism and an additional ejection mechanism, which makes the structure complex, prone to failure, and reduces processing efficiency.

[0004] Therefore, it is necessary to provide a new stamping and positioning equipment for automotive parts to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a stamping and positioning device for automotive parts.

[0006] The stamping and positioning equipment for automotive parts provided by this utility model includes: a base plate, a working platform fixedly connected to the top of the base plate, a punch installed at the top of the working platform, support columns symmetrically fixedly connected to the top of the base plate, receiving blocks fixedly connected to the tops of the two support columns, hydraulic cylinders installed inside the receiving blocks, pressure plates fixedly connected to the driving ends of the hydraulic cylinders, grooves opened at the bottom ends of the pressure plates corresponding to the positions of the working platform, guide components installed on the inner walls of the adjacent sides of the two support columns, dampers symmetrically fixedly connected to the top of the working platform, metal frames fixedly connected to the telescopic ends of the two dampers, receiving cavities opened at the four corners of the working platform, elastic components installed inside the receiving cavities, support blocks fixedly connected to the four corners of the top of the base plate, fixing rods fixedly connected to the tops of the support blocks, baffles fixedly connected to the tops of the fixing rods, strong springs sleeved on the outside of the fixing rods, sliding discs slidably connected to the outside of the fixing rods, and pressure blocks fixedly connected to one side of the sliding discs.

[0007] Preferably, the guide assembly includes a guide rod, the outer side of which is fixedly connected to the inner wall of one side of the support column, and a guide block is slidably connected to the outer side of the guide rod.

[0008] Preferably, the elastic component includes a buffer spring, which is disposed inside the receiving chamber. A limit plate is slidably connected to the inner wall of the receiving chamber, and support rods are slidably connected to the inner walls at the four corners of the top of the working platform.

[0009] Preferably, the bottom ends of the two support columns on their adjacent sides are fixedly connected to the left and right sides of the work platform, the inner wall of the metal frame is in contact with the outside of the punch, and the lateral adjacent sides of the multiple support blocks are fixedly connected to the left and right sides of the work platform.

[0010] Preferably, the two ends of the strong spring are fixedly connected to the side of the stop plate and the sliding plate, and the pressure block is in contact with the top of the metal frame when the plate is not being pressed.

[0011] Preferably, the adjacent sides of the two guide blocks are fixedly connected to the left and right sides of the pressure plate, and the outer side of the guide block is slidably connected to the inner wall of one side of the support column.

[0012] Preferably, the top end of the buffer spring is fixedly connected to the bottom end of the limiting plate, and the bottom end of the buffer spring is fixedly connected to the bottom end of the inner wall of the receiving chamber.

[0013] Preferably, the top ends of the plurality of support rods are fixedly connected to the four corners of the bottom of the metal frame, and the bottom ends of the support rods are fixedly connected to the top ends of the limiting plate.

[0014] Compared with related technologies, the stamping and positioning equipment for automotive parts provided by this utility model has the following advantages: This invention eliminates the need for pre-punching of the sheet material. By using a powerful spring to push the sliding disc and move the pressure block, it can press and position the edges of sheet materials without pre-punching. This significantly improves the equipment's adaptability to different types of auto parts sheet materials, and it is no longer limited to processing sheet materials with pre-punching, thus expanding the equipment's application range.

[0015] This invention integrates buffering and ejection functions. It uses buffer springs and dampers to buffer the pressure on components such as the metal frame during stamping to prevent damage. After stamping, the spring force of the buffer spring pushes the metal frame back to eject the workpiece. There is no need to set up separate buffering and ejection mechanisms, which simplifies the equipment structure, reduces the possibility of failure, improves the reliability of equipment operation, and also improves processing efficiency.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 5 A stamping and positioning device for auto parts includes: a base plate 1, a working platform 2 fixedly connected to the top of the base plate 1, a punch 3 installed on the top of the working platform 2, the punch 3 being a key die component for stamping, support columns 4 symmetrically fixedly connected to the top of the base plate 1 to provide stable support for the working platform 2, the bottom ends of the two support columns 4 on the adjacent side being fixedly connected to the left and right sides of the working platform 2, a receiving block 5 fixedly connected to the top of the two support columns 4, a hydraulic cylinder 6 installed inside the receiving block 5, a pressure plate 7 fixedly connected to the drive end of the hydraulic cylinder 6, and a groove opened at the bottom end of the pressure plate 7 corresponding to the position of the working platform 2, the groove cooperating with the punch 3 to realize the stamping and forming of the sheet metal; The guide assembly is installed on the inner wall of the adjacent side of the two support columns 4. The guide assembly includes a guide rod 8. The outer side of the guide rod 8 is fixedly connected to the inner wall of one side of the support column 4. The outer side of the guide rod 8 is slidably connected to a guide block 9. The adjacent side of the two guide blocks 9 is fixedly connected to the left and right sides of the pressure plate 7. The outer side of the guide block 9 is slidably connected to the inner wall of one side of the support column 4, thereby ensuring that the pressure plate 7 maintains a stable direction during the up and down movement. The damper 10 is symmetrically fixedly connected to the top of the working platform 2. The two dampers 10 are fixedly connected to a metal frame 11 at one of their retractable ends. The inner wall of the metal frame 11 is in contact with the outside of the punch 3. The two cooperate to position and press the plate. The working platform 2 has a receiving chamber 12 at each of its four corners. The elastic component is installed inside the receiving chamber 12. The elastic component includes a buffer spring 13, which is disposed inside the receiving chamber 12. A limiting plate 14 is slidably connected to the inner wall of the receiving chamber 12. The top end of the buffer spring 13 is fixedly connected to the bottom end of the limiting plate 14, and the bottom end of the buffer spring 13 is fixedly connected to the bottom end of the inner wall of the receiving chamber 12. Support rods 15 are slidably connected to the inner walls of the top four corners of the working platform 2. The top ends of the multiple support rods 15 are fixedly connected to the bottom four corners of the metal frame 11, and the bottom ends of the support rods 15 are fixedly connected to the top end of the limiting plate 14, thereby linking the movement of the metal frame 11 with the elastic force transmission of the buffer spring 13. Support blocks 16 are fixedly connected to the top four corners of the base plate 1. The horizontally similar sides of multiple support blocks 16 are fixedly connected to the left and right sides of the work platform 2. The top of the support block 16 is fixedly connected to the fixing rod 17. The top of the fixing rod 17 is fixedly connected to the baffle 18. A strong spring 19 is sleeved on the outside of the fixing rod 17. A sliding plate 20 is slidably connected to the outside of the fixing rod 17. The two ends of the strong spring 19 are fixedly connected to the baffle 18 and the side of the sliding plate 20 that are similar to the side of the sliding plate 20. A pressure block 21 is fixedly connected to one side of the sliding plate 20. The pressure block 21 is used to press the plate placed on the metal frame 11. When the plate is not being pressed, the pressure block 21 is in contact with the top of the metal frame 11.

[0021] The working principle of the automotive parts stamping and positioning equipment provided by this utility model is as follows: First, the operator places the auto parts sheet to be processed on the metal frame 11 and the punch 3. At this time, the strong spring 19 will play a role. The elastic force of the strong spring 19 pushes the sliding plate 20 to slide along the fixed rod 17. While the sliding plate 20 slides, it drives the pressure block 21 to move, so that the pressure block 21 presses the edge of the sheet placed on the metal frame 11, thereby achieving the initial positioning of the sheet and preventing the sheet from shifting during the subsequent stamping process. Next, the hydraulic cylinder 6 is activated. The hydraulic cylinder 6 starts to move, and its drive end pushes the pressure plate 7 to move downward. During the downward movement of the pressure plate 7, the guide component will also operate synchronously. The guide block 9 slides along the guide rod 8. The guide rod 8 provides a stable sliding track for the guide block 9, so that the pressure plate 7 can move downward smoothly and accurately, ensuring that the groove at the bottom of the pressure plate 7 can be accurately aligned with the plate, metal frame 11 and punch 3 below. As the pressure plate 7 continues to move downward, it will come into contact with the plate and apply pressure to it. After the plate is subjected to pressure, its edge part will push the metal frame 11 to move downward as well. When the metal frame 11 moves downward, it will drive the support rod 15 to move downward together. When the support rod 15 moves downward, it will push the limiting plate 14 to slide on the inner wall of the receiving chamber 12. During the sliding process of the limiting plate 14, the buffer spring 13 will be compressed. At the same time, the damper 10 will also be compressed due to the downward movement of the metal frame 11. The damper 10 and the buffer spring 13 work together to buffer, preventing the metal frame 11 and other components from being damaged due to excessive pressure. During this process, the middle part of the plate will be squeezed between the bottom groove of the pressure plate 7 and the punch 3, thereby undergoing plastic deformation and gradually forming the required shape of the auto parts, completing the forming process of the workpiece. After the stamping is completed, the driving end of the hydraulic cylinder 6 drives the pressure plate 7 to reset upwards. The guide block 9 in the guide assembly slides along the guide rod 8 again, and the auxiliary pressure plate 7 rises smoothly. As the pressure plate 7 rises, its pressure on the sheet metal and metal frame 11 disappears. At this time, the compressed buffer spring 13 releases its elastic force, pushing the limit plate 14 to move upwards. The limit plate 14 moves upwards, driving the support rod 15 to rise. The support rod 15 then pushes the metal frame 11 to reset upwards. At the same time, the damper 10 will also gradually extend and reset. During the process of the metal frame 11 resetting upwards, the formed auto parts will be lifted upwards together. When the workpiece is lifted to a suitable height, the operator can easily remove the formed workpiece from the metal frame 11.
