[0053] The present invention will be further described below in conjunction with the accompanying drawings.

[0054] Cable terminal crimping is a process widely used in wire connection, mainly used to tightly connect wires and terminals together to achieve current conduction and signal transmission. Crimping can make the conductor of the wire closely contact with the contact surface of the terminal, thereby improving the current conduction efficiency and reducing resistance. And because crimping can reduce resistance, it can reduce the temperature rise of the wire, which is conducive to extending the service life of the wire.

[0055] The existing cable terminal crimping mainly relies on manual operation, which not only causes the core wire to become loose after crimping, affecting the reliability of the connection, but also requires manual replacement of the crimping die. Therefore, how to provide a crimping device with stable crimping quality and high production efficiency has become an urgent problem to be solved.

[0056] Embodiment 1

[0058] As can be seen from the above, by setting up multiple die stations, a structural basis is provided for installing multiple crimping dies. Workers can place different crimping dies on multiple die stations according to processing requirements, and drive the die device 30 to move in the length direction through the die changing device 20, so that the required die station is aligned with the lifting drive 40, and the selection and switching of the crimping dies are realized. There is no need to replace the crimping dies every time crimping is performed. It is only necessary to place the cable in the corresponding crimping station, and then align the crimping station with the lifting drive 40. The aligned die station is driven to work by the lifting drive 40 to complete the crimping, thereby improving the degree of automation and production efficiency. There is no need to manually replace the crimping dies, which reduces the time and error of manual operation, and also improves the crimping quality and reliability, which can ensure the crimping quality of each terminal and the quality of the entire cable connection.

[0059] It should be noted that multiple crimping stations are respectively equipped with crimping dies, and the crimping dies on each crimping station are different to meet the crimping requirements of cables with different specifications, materials, and crimping parameters. Therefore, by setting up multiple crimping stations, it is possible to meet the crimping requirements of cables with different specifications and materials, and has strong adaptability.

[0060] It should also be noted that if Figure 3 As shown, the length direction is parallel to the X direction, and the height direction is parallel to the Z direction.

The die changing device 20 drives the die device 30 to move in the length direction so that the required die station is aligned with the lifting drive 40 to realize the selection and switching of the crimping dies. There is no need to replace the crimping dies every time crimping is performed. It is only necessary to place the cable at the corresponding crimping station and align the crimping station with the lifting drive 40. The lifting drive 40 drives the aligned die station to work and completes the crimping, thereby improving the degree of automation and production efficiency. There is no need to manually replace the crimping dies, which reduces the time and error of manual operation, and improves the crimping quality and reliability, thereby ensuring the crimping quality of each terminal and the quality of the entire cable connection.

[0066] It should be noted that multiple crimping stations are respectively equipped with crimping dies, and the crimping dies on each crimping station are different to meet the crimping requirements of cables with different specifications, materials, and crimping parameters. Therefore, by setting up multiple crimping stations, it is possible to meet the crimping requirements of cables with different specifications and materials, and has strong adaptability.

[0067] It should also be noted that if Figure 3 As shown, the length direction is parallel to the X direction, and the height direction is parallel to the Z direction.

[0071] The lower die assembly 310 is driven to move by the die changing device 20, and the upper die assembly 320 moves together with the lower die assembly 310, so that one of the upper die modules 3201 is aligned with the lifting drive 40, and the selection and switching of the crimping die is realized. The upper die module 3201 is driven downward by the lifting drive 40, and the upper die module 3201 and the corresponding lower die module 3101 complete the crimping of the workpiece on the crimping station.

[0072] It should be noted that the number of the upper pressure modules 3201 and the lower pressure modules 3101 is equal, and the specific number is set according to the needs, and this application does not make any specific restrictions. Figure 3 As shown, the number of the upper pressing modules 3201 and the number of the lower pressing modules 3101 are both four.

[0073] It should also be noted that an upper crimping station is provided on the upper pressing module 3201, and a lower crimping station is provided on the lower pressing module 3101.

[0078] By movably setting the upper mounting seat 3202 on the corresponding lower mounting seat 3103, the movement of each upper mounting seat 3202 is independent of each other. When the upper mounting seat 3202 connected to the lifting drive member 40 moves in the height direction, it will not interfere with other adjacent upper mounting seats 3202. By forming an upper crimping station on the upper mounting seat 3202, an upper crimping groove and an upper die guide 3204 are set on the upper crimping station to provide a structural basis for crimping.
