Disassembly tongs are a powerful assistant in realizing the disassembly and assembly of scrap vehicles, as well as the cracking of steel frames, and the treatment of scrap steel. The formulation and innovation of the products ensure the operation and excellent cutting consumption, and the characteristics are better than usual.

For the connection of spare parts of the disassembly pliers, the bolt is one of the main connection standard parts. The bolt tightening can usually meet the tightening specification, and there is sliding between the screw cap and the top support surface of the bolt and the support surface of the connected part after tightening. Friction. Therefore, under the static load and the operating temperature change is not large, it can ensure that the connection is clamped and not loosened.

Disassembly pliers

In order to reduce or avoid the occurrence of accidents, it is very 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, industrial equipment tightening, and long-term tightening. Industrial equipment tightening and friction tightening are called dismountable tightening, and long-term tightening is called non-dismountable tightening.

Friction tightening is the application of gaskets, lock nuts and double screw caps. One side of the lock nut is made into a non-circular narrowing or axially narrowing after splitting. When the screw cap is tightened, the closing edge expands, and the elasticity of the closing opening is used to clamp between the screwed external threads. This type of tightening structure is simple, reliable, and can be repeatedly disassembled and assembled without reducing the tightening characteristics.

Industrial equipment tightening methods use split pins, stop gaskets, and string galvanized steel wire ropes. The method of tightening industrial equipment is very reliable.
