Description

Technical Field

[0001] This utility model relates to the field of connector terminal manufacturing technology, specifically a stamping die for automotive connector terminals. Background Technology

[0002] Automotive connector terminals are core components in automotive electrical systems that enable signal transmission and power connection. Their precision, reliability, and production efficiency directly affect the overall vehicle performance. With the rapid development of new energy vehicles and intelligent driving technologies, the level of automotive electronics has significantly increased, leading to an explosive growth in the demand for connector terminals. This, in turn, places higher demands on terminal dimensional accuracy, material utilization, and production flexibility.

[0003] Currently, the production of automotive connector terminals mainly employs multi-station progressive stamping dies, achieving integrated forming of terminals through continuous punching, bending, and stretching processes. However, the positioning system of traditional stamping dies is typically designed for raw material strips of a single size (such as a specific width or thickness). When producing terminals of different specifications, the entire set of dies or core components must be manually changed, resulting in long downtime and reduced production efficiency. Therefore, a stamping die for automotive connector terminals is proposed. Utility Model Content

[0027] Example

[0028] In existing technologies, the positioning system of traditional stamping dies is usually designed for raw material strips of a single size. When producing terminals of different specifications, the entire set of dies or core components must be manually replaced, resulting in long downtime and reduced production efficiency.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a stamping die for automotive connector terminals, including a lower die assembly 10, the lower die assembly 10 including a lower template 11, a concave die 13, a spring 18, a slide rod 19, a support 110, a pneumatic telescopic rod 111, a pressure plate 112 and a pressure block 113;

[0030] A die 13 is fixedly connected to the top of the lower template 11. Springs 18 are symmetrically fixedly connected to the inner sidewall of the die 13. A slide rod 19 is fixedly connected to one end of the spring 18, and a support 110 is fixedly connected to one end of the slide rod 19. The support 110 is slidably connected to the top of the lower template 11. A pneumatic telescopic rod 111 is symmetrically fixedly connected to the support 110. A pressure plate 112 is fixedly connected to the top of the pneumatic telescopic rod 111, and a pressure block 113 is fixedly connected to the bottom of the pressure plate 112. Pulling the slider 15 moves the positioning pin 17 to the preset position. After it is in place, the slider 15 is fixed by the locking bolt 16. Then, the support 110 is pulled to move... The machine moves and places the raw material between two supports 110. The spring force of the spring 18 drives the supports 110 to clamp the raw material and pushes the raw material to contact the positioning pin 17. It can adapt to raw materials of different widths, improving the flexibility and versatility of the device. Then, the pneumatic telescopic rod 111 works to drive the pressure plate 112 to move. The pressure block 113 presses the raw material against the surface of the supports 110 and the die 13. The upper template 21 is moved by the stamping machine to perform stamping operation on the raw material. When producing products of different specifications, only the stamping die needs to be adjusted. There is no need to replace the die or parts, saving operation time and improving production efficiency.

[0031] In this embodiment, specifically: the lower mold assembly 10 also includes a guide rail 14, a slider 15, a locking bolt 16, and a positioning pin 17;

[0032] The top of the lower template 11 is fixedly connected to a guide rail 14, and the top of the guide rail 14 is slidably connected to a slider 15. The inner side wall of the slider 15 is threadedly connected to a locking bolt 16, and the inner side wall of the slider 15 is detachably connected to a positioning pin 17. The dimension exceeding the edge of the die 13 is calculated according to the material size, and the positioning pin 17 is moved to a preset position so as to quickly position the material during mass production. The friction between the slider 15 and the guide rail 14 is increased by tightening the locking bolt 16 to prevent the slider 15 from moving.

[0033] In this embodiment, specifically: the top of the lower template 11 is symmetrically and fixedly connected with guide sleeves 12, and the lower template 11 is fixed on the worktable.

[0034] In this embodiment, specifically: the guide rail 14 is disposed on the rear surface of the die 13, and the slider 15 moves along the guide rail 14 to adjust the position of the positioning pin 17. When processing raw materials of different sizes, the position of the positioning pin 17 is changed to meet the needs of the production process.

[0035] In this embodiment, specifically: an upper mold assembly 20 is provided above the lower mold assembly 10, and the upper mold assembly 20 includes an upper template 21 and a punch 22;

[0036] The bottom of the upper template 21 is fixedly connected to a punch 22. The upper template 21 is installed on the stamping machine, and the upper template 21 is moved by the operation of the stamping machine.

[0037] In this embodiment, specifically: the punch 22 is disposed above the die 13, and the punch 22 and the die 13 cooperate to complete the stamping process of the automotive connector terminal material.

[0038] In this embodiment, specifically: the bottom of the upper template 21 is symmetrically and fixedly connected with guide posts 23, and the size of the guide posts 23 matches the inner diameter of the guide sleeve 12.

[0039] In this embodiment, specifically: the guide post 23 is inserted into the inner wall of the guide sleeve 12, and the guide post 23 and the guide sleeve 12 cooperate to ensure that the lower die and the upper die can cooperate accurately during the stamping process.

[0040] The working principle or structural principle is as follows: the upper template 21 is installed on the stamping machine, and the lower template 11 is fixed on the worktable. Pulling the slider 15 moves the positioning pin 17 to the preset position. After it is in place, the slider 15 is fixed by the locking bolt 16. Then, the support 110 is pulled to move and the raw material is placed between the two supports 110. The elastic force of the spring 18 drives the support 110 to clamp the raw material and pushes the raw material to contact the positioning pin 17. Then, the pneumatic telescopic rod 111 works to drive the pressure plate 112 to move. The pressure block 113 presses the raw material onto the surface of the support 110 and the die 13. The stamping machine drives the upper template 21 to move and perform a stamping operation on the raw material.

[0041] In summary, this utility model uses the bracket 110 to position the stamping raw material for automotive connector terminals, and utilizes the spring force 18 to drive the slide rod 19 to move, allowing the bracket 110 to clamp the raw material. This allows it to accommodate raw materials of different widths, improving the flexibility and versatility of the device. The pneumatic telescopic rod 111 drives the pressure plate 112 to move, fixing the raw material and adapting to the processing needs of raw materials of different thicknesses. When producing products of different specifications, there is no need to change molds or components, improving production efficiency.
