Chain used for diamond chain saw

Abstract

The present invention discloses a chain for diamond chain saw, which comprises chain bodies, diamond segments, connecting pieces and a connecting shaft, wherein, two ends of each connecting piece are provided with connecting holes, and two ends of the each chain body are provided with body holes; the connecting pieces are sleeved in the connecting shaft through the connecting holes of the connecting pieces; two ends of the connecting shaft are inserted in and connected fixedly with the body holes at the same ends of the upper and lower chain bodies, and two ends of the upper and lower chain bodies are connected movably with one end of the adjacent connecting piece respectively; the diamond segments are connected fixedly on the upper and lower chain bodies, and a sealing washer of the connecting shaft is arranged between the connecting pieces and the upper and lower chain bodies. The present invention is not easy to produce chain removal or rupture, and can be used for sawing and cutting the materials with strong grinding performance, such as segments, concrete, and so on. The connecting pieces of the present invention are also able to be provided with protection teeth whose anglesface to the diamond segments so as to avoid the edges of the diamond segments from breaking and improve the sharpness of the present invention.

Description

Technical field: [0001] The invention relates to a diamond sawing tool, in particular to a chain for a diamond chain saw. Background technique: [0002] The diamond sawing tools used now include diamond circular saw blades, diamond gang saws, diamond wire saws, etc. Diamond wire saws are mainly used for large-scale mining, diamond gang saws are mainly used for sawing marble plates, and diamond circular saw blades are widely used for sawing stone, concrete, asphalt and other materials, so now municipal road and bridge maintenance and gas, tap water In the rescue and disaster relief operations of power and communication engineering, diamond circular saw blades are used to cut roads, walls and other components, but there are some shortcomings in the sawing of diamond circular saw blades. For example, diamond circular saw blades can only be used for straight saw Originally only need to saw a small area, but because the circular saw blade can not perform corner sawing, resulting...

AI Technical Summary

Problems solved by technology

However, when the chain saw cuts strong abrasive materials such as stone and concrete, the mud and sand generated easily enter the connecting parts of the chain links. These mud and sand will wear the connecting shaft, make the connecting shaft smaller, and loosen the connection between the chain links. , the chain becomes longer, causing detachment or chain breakage, making it almost impossible to use the chain saw to cut abrasive materials such as stone and concrete
