Electrician's tool - pliers
Clips are divided into several types. All clips can be considered wiring if rubber or plastic tubes are placed on them. The levers of the pliers are made of steel class U7, U7A, 7HF, 8HF. When using the tongs, you need to remember a few rules that will help them enjoy longer.
Pins can bite soft metal wires like copper. and aluminum of random cross-section. End mills should not bite into steel wire whose cross-section is more than 1 mm. Hard steel, it is better to bite the wire with pliers, and it is best to cut it with a hammer, placing it at a sharp angle, besides, it will be easier to do it if it is bent. The larger the cross-section of the wires of the wire to be cut, the closer to the middle of the cut from the edges, the object to be cut should be located.
When working, you should hold the knives with your thumb on one handle, index, middle and nameless for the other handle, and the little finger is usually placed between the handles, part them after a snack.If the clips «go» tightly, then you can help the little and ring finger. When the handles are pressed, the jaw blades should be in close contact. The distance between the edges cannot be more than OD mm. Be careful getting your finger between the cutter levers, especially those probably on old wire cutters. If your nippers sometimes try to pinch the skin, place your fingers further away, closer to the ends of the handles.
With frequent use, the axle connecting the arms of the pliers will wear out. Yes, in order to slow down this process, it is necessary to lubricate the axle. If the clearance between the axis and the cutter levers is too large, you can try to distribute the axis. To do this, place the clamps on a solid solid base, with the axis towards you. To the center or to an area close to it, apply a beard and with strong blows of a hammer create a depression, the same done on the other side of the axle. This should result in less ground clearance. between the axle and the levers. If the attempt is not successful, you will have to replace the axle or buy new pliers. The damaged axis is removed by drilling. A single nail is quite suitable as a material for the new axle. Its steel is quite suitable for strength.
Articulated milling cutters are also used. One of their advantages is that in execution they double the initial pressure on the levers of the work pliers. But the edges of these clips, as practice shows, do not withstand high loads and may crack during operation. This is essential lack of such a tool. There are nail clips and side clips. In general, it is forbidden to bite steel products with side cutters, they can only handle soft metals.It is convenient to use tweezers to remove the insulation wires. For good biting, it is important to determine when the pins bite the insulation of the wires. After that, you should stop squeezing the handles. clips and start stripping the wire. Scratching is not required when stripping the copper from which the core is made, this can lead to mechanical breakage. If the diameter of the copper core does not exceed 0.5-0.8 mm, then the workers should not scratch the edges of the wire knives. In addition, this can lead to a decrease in the cross-section of the vein, and hence its strength, but also contributes to the longitudinal fracture of the vein.
Cutting pliers can be sharpened if they are dull. If the clips are jagged, then they will not be able to fully perform their functions. True, if the pliers have two serrated edges opposite each other, this will even help them to cope by removing the insulation, practically without touching the wires.
