How to control the dismantling pliers to prevent the bolts from loosening at work
Car pliersIt is a powerful assistant for the disassembly and assembly of scrap vehicles, as well as the cracking of the steel frame structure, and the treatment of waste steel. The product formulation and innovation capabilities ensure the operation process and excellent cutting consumption, which is better than usual.
For the connection of spare parts of the disassembly pliers, the bolt is one of the important connecting parts. The bolt tightening can usually meet the clamping specifications, and there is sliding between the fulcrum surface of the nut and the top of the bolt head and the fulcrum surface of the connected part after tightening. Friction. Therefore, when the static load and the working temperature change is not too large, it can ensure that the connection is clamped and not loosened.
In order to reduce or prevent the occurrence of accidents, it is more necessary to do a good job of inspection and tightening in the repair and maintenance work of dismantling pliers. Common bolt tightening methods include friction tightening, mechanical equipment tightening, and long-term tightening. Mechanical equipment tightening and friction tightening are called disassembly tightening, and long-term tightening is called non-disassembly tightening.
Friction tightening is the application of gaskets, lock nuts and double nuts. One side of the lock nut is made into a non-circular necking or a cracked rear wheel necking. When the nut is tightened, the closing edge expands, and the elasticity of the closing is used to clamp between the screwed external threads. This type of tightening structure is simple and reliable, and can be disassembled and assembled many times without reducing the tightening characteristics.
The method of tightening the mechanical equipment of the disassembly pliers is to use split pins, stop gaskets, and string galvanized steel wire ropes. The method of tightening mechanical equipment is more reliable.
