Description

Coaxial double-head automatic terminal machine

technical field

The utility model relates to a terminal punching machine, in particular to a coaxial double-head automatic terminal punching machine.

Background technique

At present, the main terminal manufacturers in the market include IPX, Xuande, Kexincheng, etc.; the development of the terminal structure has mainly been divided into 5 generations of products, and each generation is subdivided according to the size of the wire harness (such as 0.81 for the 4th generation; 1.13 for the 4th generation, etc.). Coaxial cable manufacturers mainly include Shenyu, Chengjia, Zhongzheng, etc., and their wire harness sizes are various (such as 0.64mm, 0.81mm, 1.13mm, etc.). At present, the factory mainly adopts semi-automatic production for the terminal of the coaxial cable, that is, the wiring harness is arranged manually, and then one end of it is put into the terminal and riveted by the terminal machine. For the accuracy of wiring harness placement, some factories rely entirely on human eyes to identify, and some use a camera to enlarge the terminal on the display screen to show its positional relationship with the wiring harness. This positioning method leads to poor accuracy, and the basic position tolerance range is ± About 0.3mm. One of such error ranges: it will lead to a larger signal deviation range of the produced products, and the other: it will cause the connection between the terminal and the wiring harness to be unreliable. The efficiency of semi-automatic production will also vary depending on the size of the wire harness (for example, when producing 0.64mm wire harnesses with 4th generation terminals, the output of single-headed terminals is only 600-800PPH; when 4th-generation terminals are 1.13mm wire harnesses, the output of single-headed terminals is 1000 -1200PPH). Factors such as physical and visual fatigue caused by manual long-term work will directly affect production efficiency and product accuracy.
