As we all know, cable cutting is the beginning of a series of related work related to the connection of electrical equipment. In order to cut the cable into different shapes, different materials and different diameters, a variety of matching cable cutting tools should be used.
To understand how ratchet cable cutters make cutting cables less laborious, you must understand the classification of cable cutters:
1. Ratchet cable cutter
The ratchet type cable cutter includes a handle device, a cutting device and a pushing device. The pushing device of the cutting pliers is driven by two gears to drive the teeth on the movable knife body to advance forward, so that the movable knife body and the fixed The circular part formed by the blade of the knife body is gradually reduced to achieve the effect of shearing. The gear pushes the gear on the movable knife body in a tangential direction, and the gear pushes the teeth of the movable knife body with multiple teeth. , So that the pushing force is dispersed on the clamping teeth, so that the clamping teeth are not easily damaged, so as to prolong its service life. Nowadays, the ratchet cable cutter has become the industry's first choice for cutting cables.
2. Manual cable cutter
The most primitive cutting cable, manual electric cutting cable. The manual cable cutter is similar to ordinary scissors, with a larger shape, a longer handle (leverage principle), and a harder blade. Manual cable cutters can easily cut small cables, but large cables require a lot of hand power, so they have been replaced by the industry.
3. Hydraulic cable cutter
The hydraulic cable cutter includes a clamp, which is characterized in that a clamping groove, a chain ring groove, a movable knife guide groove and a static knife guide groove are processed on the clamp, and a hydraulic cylinder with a flange is clamped in the clamping groove. Plunger, the left end of the movable knife is connected with the right end of the plunger through the return plate, and then the hydraulic cylinder body is clamped into the clamping groove of the fixture through its flange, the movable knife is placed in the movable knife guide groove of the fixture, and the static knife is placed Into the static knife guide groove of the fixture. When in use, first put the sheared chain link into the chain link groove, and then inject high-pressure liquid into the cylinder. Under the action of hydraulic pressure, the plunger pushes the movable knife to move, and cooperates with the static knife to form a shearing force. The chain is cut. Hydraulic cable cutters are not widely used in the industry due to their relatively complicated operation process and no ratchet cable cutters.
4. Electric cable cutter
The electric cable cutter uses a lithium battery as the power source. There are multiple sets of gears inside the equipment, and the blades are opened and closed through the rotation of multiple sets of gears. Electric cable cutters can easily cut large cables. Since electric cable cutters need lithium batteries to charge, the experience is not as good as ratchet cable cutters, and the use is relatively cumbersome, so they have not been widely promoted in the industry.
