Description

Technical Field

[0001] This utility model belongs to the field of battery steel shell processing technology, and in particular relates to a continuous stamping die for battery steel shells. Background Technology

[0002] As a key structural component of batteries, the manufacturing precision and production efficiency of battery steel casings directly affect the overall performance and manufacturing cost of batteries. Stamping is the core process in the manufacturing of battery steel casings, and the performance of the die directly determines the forming quality and efficiency. In modern large-scale production, there is an urgent need for continuous, high-speed, and high-precision stamping production.

[0003] In existing technologies, stamping and demolding are accomplished by setting specific die cores and ejection structures. However, such dies still have some inherent defects in practical applications: First, after bearing the stamping force, the die usually relies on a single reset mechanism to return to its original position, which is slow and lacks stability, resulting in a prolonged stamping cycle and making it difficult to meet the production rhythm of high-speed continuous stamping. Second, during continuous feeding, the steel shell strip or preform lacks effective guidance and limiting, making it prone to deviation during feeding, resulting in inaccurate stamping position, poor product consistency, and increased scrap rate. To address these issues, we provide a continuous stamping die for battery steel shells to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a continuous stamping die for battery steel shells. By using a return spring and a die module in combination, rapid reset can be achieved, improving the efficiency of continuous stamping. At the same time, the use of an auxiliary ring frame can control the continuous movement of different battery steel shell materials, thus achieving high-efficiency production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a continuous stamping die for battery steel shells, including a stamping plate; a stamping opening is provided in the middle of the upper end of the stamping plate, and a concave module is provided inside the stamping opening, which is flush with the upper end of the stamping plate.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1 to 6 This utility model is a continuous stamping die for battery steel shell, including a stamping plate 1; as a basic support component, a stamping opening 104 is opened in the middle of its upper end to accommodate the die 3 and perform stamping operations. The stamping plate 1 provides a stable working platform to ensure the accuracy of the stamping process. The stamping opening 104 is opened in the middle of the upper end of the stamping plate 1. The die 3 is flush with the upper end of the stamping plate 1 inside the stamping opening 104. The die 3 is set inside the stamping opening 104 and is flush with the upper end of the stamping plate 1 for directly forming the battery steel shell. Two linkage rods 301 arranged in a ring around the lower end of the concave module 3 are fixed thereon. The linkage rods 301 transmit the punching force, allowing the concave module 3 to move with the punch while ensuring the stability of the concave module 3. Movable holes 105 are provided at the bottom of the punching port 104 corresponding to the positions of the two linkage rods 301. Return springs 303 are provided at the lower part of the punching plate 1 corresponding to the positions of the two movable holes 105. After punching, the return springs 303 provide elastic force, causing the concave module 3 to automatically return to its original position, achieving rapid reset and improving continuous punching efficiency. The linkage rods 301 pass through the movable holes 105. The lower end of the moving hole 105 is provided with a circular plate 305 connected to the upper end of the return spring 303. The circular plate 305 is fixed to the lower end of the linkage rod 301 and connected to the upper end of the return spring 303. It is used to uniformly transmit pressure and compress the return spring 303. An auxiliary ring frame 2 is provided directly above the stamping plate 1. The three circular openings on the upper end face of the auxiliary ring frame 2 are the same size as the opening of the stamping port 104. It is located directly above the stamping plate 1. The three circular openings on its upper end face are the same size as the opening of the stamping port 104. It is used to guide and position the battery steel shell material and can continuously control the movement of the metal steel shell raw material.

[0024] Furthermore, the protrusion at the lower end of the recessed module 3 passes through the through hole at the bottom of the stamping plate 1, allowing the recessed module 3 to move up and down during the stamping process to achieve continuous stamping.

[0025] Specifically, according to Figure 2 , Figure 5 and Figure 6 It can be seen that a base frame 101 is fixed to the lower end of the stamping plate 1. The base frame 101 is fixed to the lower end of the stamping plate 1 to provide overall support and stability, ensuring that the device does not vibrate during high-speed stamping. L-shaped plates 102 are fixed to the lower ends of the stamping plate 1 located to the left and right of the stamping opening 104. The L-shaped plates 102 are fixed to the lower end of the stamping plate 1 and located to the left and right of the stamping opening 104. They are used to support the lower end of the return spring 303 and prevent the return spring 303 from shifting. The lower end of the return spring 303 abuts against the inner wall of the L-shaped plate 102. A positioning rod 302, which is inserted into the return spring 303, is fixed on the lower end face of the circular plate 305. A positioning hole 103 is provided through the lower end of the L-shaped plate 102 at the position corresponding to the positioning rod 302. The positioning rod 302 is fixed to the lower end of the circular plate 305 and inserted into the return spring 303, which plays a guiding role and prevents the return spring 303 from bending or shifting during compression. The positioning hole 103 ensures that the positioning rod 302 can move up and down normally and avoids motion interference. An assembly hole 304 is provided on the lower end face of the linkage rod 301. A screw 306 is fixed on the upper end face of the circular plate 305 and screwed into the assembly hole 304. The assembly hole 304 is provided on the lower end face of the linkage rod 301 and the screw 306 is fixed on the upper end of the circular plate 305. The screw connection facilitates the disassembly and replacement of the recessed module 3 and the linkage rod 301, making maintenance convenient.

[0026] Among them, according to Figure 3 and Figure 4 It can be seen that the upper surface of the stamping plate 1 located in front of and behind the stamping port 104 is provided with a strip-shaped opening 106. The left and right sides of the stamping plate 1 are provided with screw holes 107 that are connected to the inside of the strip-shaped opening 106. Each strip-shaped opening 106 is provided with a slide rod 202. The threaded parts at both ends of the slide rod 202 spirally pass through the screw hole 107. The two ends of the slide rod 202 are fixed through the screw hole 107 to form a sliding track. The auxiliary ring frame 2 slides at the upper end of the stamping plate 1. The auxiliary ring frame 2 can facilitate the movement of the battery steel shell raw material. The lower end of the auxiliary ring frame 2 is fixed with two moving blocks 201 that slide in the corresponding strip-shaped opening 106. Each moving block 201 is sleeved on the slide rod 202 through the through hole on the side wall.

[0027] The operation process of this embodiment is as follows: First, no force is applied to the auxiliary ring frame 2. The opening in the middle of the auxiliary ring frame 2 is aligned with the position of the stamping port 104. The battery steel shell material is located above the stamping plate 1. Therefore, the auxiliary ring frame 2 limits the battery steel shell material. Therefore, when the external punch moves downward, it applies pressure to the concave module 3, and the concave module 3 moves downward accordingly. The linkage rod 301 moves downward through the movable hole 105, which drives the circular plate 305 to compress the reset spring 303. The downward movement of the concave module 3 causes the battery steel shell material to be formed in the stamping port 104. After stamping is completed, the punch is lifted, and the elastic force of the return spring 303 pushes the concave module 3 back to its original position through the circular plate 305 and the linkage rod 301. At this time, the auxiliary ring frame 2 is moved to align one of its two circular openings with the stamping port 104, and the internal battery steel shell material is moved to the stamping port 104 position to prepare for the next stamping. The whole process is carried out continuously to achieve efficient production.

[0028] It should be noted that the auxiliary ring frame 2 used is connected to an external cylinder. The external cylinder controls the auxiliary ring frame 2 to move back and forth, thereby enabling the auxiliary ring frame 2 to move the battery steel shell material at different positions to the stamping port 104 position so as to continuously perform stamping work.
