Description

Technical field:

[0001] The utility model relates to the technical field of wire material processing, in particular to a crimping module. Background technology:

[0002] Wires and cables are basic components for transmitting power and signals, and play a vital role in modern electrical and electronic systems. Wires usually refer to a single conductive material, while cables are a combination of multiple wires twisted together and wrapped with an insulation layer and a sheath. They are widely used in power transmission, communication networks, electronic equipment, and industrial automation to ensure the efficient transmission of power and information.

[0003] Wire processing plays an important role in modern manufacturing, involving a variety of precision processes to ensure product performance and quality. Among them, the terminal crimping process, as one of the key links in wire processing, plays a vital role in the electrical connection and mechanical properties of the cable. From raw materials to finished products, wire processing goes through multiple steps such as cutting and segmenting, end stripping, wire twisting, and terminal crimping. The precision and quality of each step directly affects the reliability of the final product.

[0004] Among them, terminal crimping, as a key step in wire processing, directly determines the electrical and mechanical connection performance of the cable. Through the automatic crimping module, the terminal is firmly crimped on the stripped wire to ensure the reliability and durability of the connection. The quality of terminal crimping is crucial to the overall performance of the cable, because poor crimping can lead to poor contact, looseness or even breakage, which will affect the service life and function of the cable. Therefore, every detail in the crimping process needs to be strictly controlled to ensure the crimping strength and electrical contact of the terminal.

In the technical solution disclosed in the patent, the crimping head 4 adopts pneumatic control. Due to the low precision of pneumatic control, it is easy to apply excessive pressure or insufficient pressure. In addition, the patent adopts unidirectional movement of the crimping head 4, which can easily cause transitional crimping damage between the terminal and the wire or fail to form a stable connection due to insufficient crimping force, thereby causing subsequent connection failures and affecting the service life of the wires and cables.
