Technical Field

The utility model relates to a terminal crimping equipment technical field especially relates to a pneumatic terminal crimping mould.

Background

At present, a wire harness terminal is one of the most convenient products with fastest development, large market demand and most convenient installation in the current electronic information industry, in recent years, the wire harness industry has developed to a certain height in China, and the wire harness product is not only a special product in the automobile industry and the household appliance industry, and the wire harness used in the fields of electronic appliances, instruments and meters, electromechanical equipment and the like also has to be produced in a large scale and specialization way along with the development requirements of specialization and automation production; in particular, in the automobile industry, automobile wiring harness elements are called automobile nerves and are carriers for controlling electric signals of automobiles. The automobile wire harness is a network main body of an automobile circuit, and the automobile circuit does not exist without the wire harness. At present, the basic form of wiring harnesses, whether for luxury automobiles or for economy and convenience automobiles, is the same, and consists of wires, terminal connectors, and other devices. In order to realize automatic and large-scale production, people punch the terminal connector into a chain shape and press the terminal and the wire harness by means of a mechanical pressing mold. The existing crimping method of the tubular terminal only can crimp the terminal with different squareness by hand or equipment, the manual crimping efficiency is low, the quality cannot be ensured, and people are easy to fatigue particularly when crimping the terminal with large squareness. The existing terminal crimping equipment can only crimp a terminal with a single specification by a single mould in function, is poor in maneuverability, high in price and incapable of being adjusted in height and adapting to crimping of various wires. In the field of wire harness processing, the tubular terminals are various in types, generally, the production of one wire harness needs to crimp the tubular terminals with various specifications, and although the existing equipment can crimp the tubular terminals, the die needs to be replaced once when the terminal with different specifications is crimped, so that the production working hours are increased, the corresponding efficiency is reduced, and the production cost is greatly increased. The terminal step pitch is small, the terminals are arranged closely, the material belt is arranged behind the rubber-covered wire crimping part, the elasticity of the whole material belt part is large, the change of the terminal step pitch is caused after feeding, cutting and crimping are carried out on a plurality of material belt parts, and adjacent places are easy to contact to cause fire after being matched with the sheath; the terminal is unstable during crimping, the rejection rate is high, and no special crimping die exists in the terminal at present. In order to avoid accidents, wire harness manufacturers determine the number of terminals in each group, then cut off the terminals by using a tool or a die, and then crimp-joint the terminals by using a common single-die. The crimping die structure has the technical problems of unstable quality and low working efficiency of the crimping.

There is therefore a need for a pneumatic terminal crimping die that can solve the above problems.
