Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an integrated forming and punching equipment for stamping parts. Background Technology

[0002] In recent years, with the increasingly fierce competition in the automotive market, major automakers have very high requirements for stamping production efficiency and very high labor costs. They all hope to reduce stamping costs by improving the stability of molds. Process engineers design and layout the process steps based on these characteristics of the parts, formulate process documents for the parts, and determine the size of the molds and the number of process steps for producing the parts. For some small parts, it is difficult to achieve the stability and speed of high-speed stamping with general automotive mold structures, thus increasing stamping costs.

[0003] In traditional stamping processes, the stamping forming and punching processes are usually carried out in a step-by-step manner. That is, the initial shape of the part is first processed by the forming die, and then the hole is processed by the independent punching die. However, for products that require high coaxiality between cylindrical surfaces and holes, the step-by-step design of forming and punching not only increases the production process, but also cannot guarantee the coaxiality between the holes and the surfaces, affecting the subsequent installation accuracy. Utility Model Content

[0004] In view of the above-mentioned existing problems, the step-by-step design of forming and punching not only increases the production process, but also cannot guarantee the coaxiality of the hole and the surface, affecting the subsequent installation accuracy. Therefore, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an integrated forming and punching equipment for stamping parts, which aims to break through and optimize the existing structure, reduce the number of stamping processes and dies, and use automated production to improve production efficiency.

[0006] To solve the above technical problems, this utility model provides the following technical solution: an integrated forming and punching equipment for stamping parts, including an upper die base, a lower die base and a stamping part, wherein a punch fixing plate is installed at the bottom of the upper die base, and spring cavities are opened on both sides of the bottom of the punch fixing plate, and nitrogen springs are installed inside the spring cavities. An upper forming block is fixedly connected between the elastic ends of the two nitrogen springs, and a forming protrusion is integrally formed in the middle of the bottom of the upper forming block. A punching punch is installed between the punch fixing plate and the upper forming block.

[0007] The lower mold base is mounted on the top and directly below the upper molding block. The middle of the top of the lower molding block is provided with a molding cavity that matches the molding protrusion.

[0008] As an improved technical solution, a T-shaped fixing hole is provided on the punch fixing plate between the nitrogen springs on both sides for the punching punch to pass through, and a mounting platform is provided at the top of the punching punch to be hung on the T-shaped fixing hole.

[0009] As an improved technical solution, a movable through hole is provided between the upper forming block and the forming protrusion for the punch to move, and the movable through hole is wide at the top and narrow at the bottom.

[0010] As an improved technical solution, the bottom of the lower molding block is provided with a connecting hole that communicates with the inside of the molding cavity, and the middle of the top of the lower mold base is provided with a discharge port located below the connecting hole.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the material block stamped off the stamping part falls directly into the interior of the connecting hole and is discharged directly through the discharge port, completing the direct discharge of waste material, reducing the steps of collecting waste material, reducing processes, and further improving work efficiency.

[0013] 2. This utility model uses a forming protrusion to first stamp the part, and then uses a punching punch to punch the part. The integrated design of forming and punching ensures that the product maintains the same angle during the stamping process, guaranteeing the coaxiality of the hole and the surface of the stamped part, and improving the pass rate of the stamped part. At the same time, the two key processes of forming and punching are integrated into the same station and completed in one stamping stroke, completely eliminating the material transfer and repeated positioning time between processes, significantly improving production efficiency, avoiding the errors caused by repeated clamping, and reducing the number of stamping processes and dies, making it more suitable for automated production, thereby improving production efficiency and reducing stamping costs.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] Reference Figures 1-2 This is the first embodiment of the present invention, which provides an integrated forming and punching device for stamping parts. This integrated forming and punching device for stamping parts includes an upper die base 1, a lower die base 12 and a stamping part 14. A punch fixing plate 6 is installed at the bottom of the upper die base 1. Spring cavities 5 are opened on both sides of the bottom of the punch fixing plate 6. Nitrogen springs 2 are installed inside the spring cavities 5. An upper forming block 15 is fixedly connected between the elastic ends of the two nitrogen springs 2. A forming protrusion 8 is integrally formed in the middle of the bottom of the upper forming block 15. A punching punch 4 is installed between the punch fixing plate 6 and the upper forming block 15, and the bottom end of the punching punch 4 passes through the forming protrusion 8 and extends to the bottom of the forming protrusion 8.

[0022] A lower forming block 13 is installed on the top of the lower mold base 12 and directly below the upper forming block 15. A forming cavity 9 that matches the forming protrusion 8 is provided in the middle of the top of the lower forming block 13.

[0023] The forming head 8 is used to stamp the first stamping part 14, and then the punching head 4 punches the stamping part 14. The integrated design of forming and punching ensures that the product maintains the same angle during the stamping process, ensuring the coaxiality of the hole and the surface of the stamping part, and improving the pass rate of the stamping part. At the same time, the two key processes of forming and punching are integrated into the same station and completed in one stamping stroke, which completely eliminates the material transfer and repeated positioning time between processes, significantly improves production efficiency, avoids the errors caused by repeated clamping, and reduces the number of stamping processes and dies, making it more suitable for automated production, thereby improving production efficiency and reducing stamping costs.

[0024] A T-shaped fixing hole 3 is provided on the punch fixing plate 6 between the nitrogen springs 2 on both sides for the punching punch 4 to pass through, and a mounting platform is provided at the top of the punching punch 4 to be hung with the T-shaped fixing hole 3.

[0025] A movable through hole 7 is provided between the upper forming block 15 and the forming protrusion 8 for the punching punch 4 to move, and the movable through hole 7 is wide at the top and narrow at the bottom.

[0026] The bottom of the lower forming block 13, directly below the forming cavity 9, has a connecting hole 10 that communicates with the inside of the forming cavity 9. The top center of the lower mold base 12, below the connecting hole 10, has a discharge port 11. The size of the discharge port 11 is larger than that of the stamping part 14. The stamped material blocks fall directly into the interior of the connecting hole 10 and are discharged directly through the discharge port 11, thus completing the direct discharge of waste materials, reducing the steps of collecting waste materials, reducing processes, and further improving work efficiency.

[0027] Based on Embodiment 1, the working principle of this utility model is as follows: The upper die holder 1 is fixed at the bottom of the punch press slide, and the stamping part 14 is placed on the lower forming block 13. The upper die holder 1 moves downward with the punch press slide. The forming protrusion 8 on the upper forming block 15 contacts the stamping part 14 first and completes the stamping of the stamping part 14 under the pressure of the nitrogen spring 2. At this time, the punch press slide continues to move downward. Due to the contact between the upper forming block 15 and the lower forming block 13, the upper forming block 15 applies a compressive force to the nitrogen spring 2, so that the nitrogen spring 2 is in a compressed state, causing the punching end of the punching punch 4 to move out from the movable through hole 7 and contact the stamping part 14 for punching. When the punch press slide reaches the bottom dead center, the forming punching is completed.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
