Use of crimping pliers Crimping pliers are necessary tools for the electric power industry to carry out wire crimping in line construction and line maintenance. Crimping pliers structure The utility model relates to a ratchet crimping tool, which comprises a movable handle, a fixed handle, a pin, a tension spring, a ratchet, an adjusting hand wheel, a pawl and a rivet, wherein the fixed handle has a ratchet on the circumference of the ratchet There is a raised tooth with a round hole in the middle of the ratchet. The ratchet is mounted on the fixed handle by a pin. The ratchet can rotate around the pin. The ratchet has a small hole on the circumference of the ratchet. One end of the tension spring is in the small hole on the circumference of the ratchet wheel. The other end of the tension spring is connected to the pin of the fixed handle; the movable handle has a pawl, and one end of the pawl is fixed on the movable handle by three rivets, and the other end of the pawl is distributed with a tooth shape, the movable handle Closed with the fixed handle, the tooth shape on the pawl and the ratchet engage. The utility model has the advantages of reasonable design, simple structure and convenient use. During the crimping process, the ratchet and the pawl are engaged, the fixed handle and the movable handle cannot be opened until the pressure is pressed into position, and the ratchet and the pawl are separated from the bite, which can be guaranteed multiple times. Crimp quality at repeated crimping. Crimping pliers category Split crimping pliers Split crimping pliers need to be equipped with corresponding pumps, which are generally suitable for electric overhead lines and underground cable lines; there are also split crimping pliers suitable for large cables. A multi-purpose machine can be used for crimping pipe clamp pressure, but also can achieve hexagonal die crimping. Cordless crimping pliers The rechargeable crimping pliers are compact and lightweight, and the push-and-roll operation buttons are arranged reasonably. It can be operated with one hand; it adopts low- and high-pressure two-stage plunger pump drive design, and the crimping is fast. The system is equipped with a safety relief valve. After the standard output, the pressure is automatically relieved. The head can be rotated by 350 degrees, which is suitable for crimping at different angles. The tool is equipped with a strap, which is especially suitable for climbing work (new type lithium battery BP-14LN can be crimped 90 times); configuration: one host, one battery, one charger, one resin kit. Manual crimping pliers It adopts high and low two-stage plunger pump drive design, which is quick and labor-saving. The system is equipped with a safety relief valve, which is automatically relieved after the standard output. [3] Air-type crimping pliers are also manual: air-type crimping pliers are suitable for bare crimp terminals of 1.25-5.5mm2, insulated terminals, insulated closed-end terminals, continuous terminals, using air pressure: 0.5~0.6MPa (5 ~6kgf/cm2, operation mode: pedal operation, can be operated by inching or continuously. The pressure connector can be replaced.
