Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a symmetrical stamping die for automobile parts. Background Technique

[0002] With the rapid development of the automobile industry, the requirements for the production efficiency and quality of automobile parts are getting higher and higher. The traditional manual or simple mechanical production methods are difficult to meet the needs of modern automobile manufacturing. Therefore, a new type of stamping die that can improve production efficiency and ensure product quality is needed.

[0003] A Chinese patent discloses a stamping die for automobile parts (publication number: CN 209255645U), which includes a machine table, a driving cylinder and a positioning table; a driving shaft is arranged at the bottom of the driving cylinder, and a punch mounting block is fixedly connected to the bottom of the driving shaft. At least two punches are installed at the bottom of the punch mounting block; the positioning table is fixedly arranged on the machine table, and the positioning table is located below the punch mounting block. However, this stamping die for automobile parts has a simple structure and single functionality. Although it can meet the basic installation requirements, when facing different complex working conditions, its adaptability and stability are often insufficient, and it is difficult to ensure product quality. Therefore, a symmetrical stamping die for automobile parts is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages that in the prior art, this stamping die for automobile parts has a simple structure and single functionality. Although it can meet the basic installation requirements, when facing different complex working conditions, its adaptability and stability are often insufficient, and it is difficult to ensure product quality, and a symmetrical stamping die for automobile parts is proposed.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a symmetrical stamping die for automobile parts described in the utility model includes a die body, and is characterized in that: the die body includes an upper die base, a lower die base is arranged below the upper die base, and guide columns are arranged between the upper die base and the lower die base. The number of the guide columns is 4 and they are arranged diagonally. A punch is arranged at the top of the upper die base, a stripper plate is arranged below the lower die base, a stripper seat is arranged below the stripper plate, a support table is arranged below the stripper seat, connecting blocks are arranged on both sides of the bottom of the support table, a raw material workpiece is arranged on one side of the stripper seat, and a feeding assembly is arranged on one side of the raw material workpiece. This symmetrical structural design helps to improve the stability and accuracy of the die, ensuring that consistent part quality can be produced during the stamping process. The setting of the guide columns helps to reduce the offset or misalignment of the die during the working process, thereby increasing the service life and production efficiency of the die. In addition, by setting the feeding assembly, automatic feeding can be realized, further improving the production efficiency and reducing the error rate of manual operation.

[0006] Preferably, the feeding component includes a clamping member. A double-rod cylinder is provided on one side of the clamping member, and the other end is associated with the raw material workpiece. An L-shaped protective frame is provided outside the double-rod cylinder. The double-rod cylinder includes a cylinder body and a piston rod associated with the cylinder body. A mounting plate is provided at the bottom of the double-rod cylinder. Support rods are provided on both sides of the bottom of the mounting plate, and a bottom plate is provided below the support rods. By using a double-rod cylinder as the driving source, rapid and stable feeding actions can be achieved, improving production efficiency. At the same time, the design of the L-shaped protective frame can protect the cylinder from external interference and damage, extending its service life. In addition, the structure of the entire feeding component is compact and occupies little space, facilitating installation on various production lines for use.

[0007] Preferably, the lower die base includes positioning pins. The positions of the positioning pins correspond to those of the upper die base. By providing the positioning pins, precise alignment between the upper and lower die bases can be ensured, avoiding deviation or misalignment during the stamping process. This helps improve the machining accuracy and consistency of the components, reducing the scrap rate and rework rate. At the same time, the design of the positioning pins can also simplify the installation and debugging process of the die, improving production efficiency.

[0008] Preferably, die holes are provided on the upper die base, lower die base, stripper plate, and stripper seat, and a die component is jointly provided. By setting die holes on multiple components and jointly forming a die component, rapid replacement and repair of the die can be achieved. When a certain component needs to be replaced or repaired, it can be simply taken out of the die for operation without disassembling the entire die system. This helps shorten the downtime and reduce the maintenance cost.

[0009] Preferably, a return spring is provided between the stripper seat and the support table, and a discharge port is provided on one side of the stripper seat. By providing the return spring and the discharge port, the discharging efficiency can be improved and the risk of damage to the components during the discharging process can be reduced. The return spring can provide stable elastic support to ensure that the stripper plate can smoothly discharge the components; while the discharge port can prevent the components from getting stuck or remaining in the die during the discharging process, avoiding production interruptions.

[0010] Preferably, a buffer spring is provided between the upper die base and the lower die base. By providing the buffer spring, the impact force and vibration generated during the stamping process on the die can be reduced, thereby extending its service life and improving production efficiency. In addition, the buffer spring can also help maintain the accuracy and stability of the die to ensure that the produced components have consistent quality and dimensional specifications.

At this time, the double-rod cylinder is in a standby state; when production needs to start, the double-rod cylinder is activated to push the clamping member 10 to send the raw material workpiece 9 into the mold area. During this process, the L-shaped protective frame 12 protects the cylinder from external interference; after the raw material workpiece 9 is sent in place, the upper die holder 2 moves downward, and the punch 1 punches the raw material workpiece 9. At this time, the guide post 19 plays a stabilizing role to ensure the alignment of the upper and lower die holders 3; at the same time, the positioning pin 18 ensures the precise alignment between the upper and lower die holders 3; after stamping is completed, the upper die holder 2 moves upward, and the unloading plate 4 and the unloading seat 5 cooperate to push the finished product out of the mold. During this process, the return spring 21 provides the necessary elastic support to ensure smooth unloading; the finished product is discharged out of the mold through the unloading port 8, completing the entire production process.
