Machining process of rock hammer chisel: After the round steel is broken, it is first heat-treated and annealed with nodular ink, and then CNC lathes and CNC milling machines are preferred. Companies with strict data control also use ordinary cars for production. Then there is the heat treatment step, salt bath furnace is preferred, but due to the strict control of salt bath furnace, most enterprises mainly use well type carburizing furnace, the quenching liquid is preferably imported quenching liquid, and the final process is shot blasting and coating ,Package.
The heat treatment process of the rock hammer chisel is optimized by overall quenching and segmental tempering. The HRC hardness value of the impact part of the breaker drill rod is 56-58, and the HRC value of the piston impact part is 45-48. Claims for drill rods: drill rods are vulnerable products, and the long-term operating medium is ore, roadbed, concrete, ships, slag, etc. Therefore, the tip of the drill rod will be worn during the working process. If the daily maintenance does not pay attention to the renewal of the inner jacket and the filling of butter, it is easy to cause the drill tail to break, so the claim identification is also a cumbersome process.
The direction of the rock hammer chisel and the forearm should be consistent, and the steel chisel and the rock surface should be as vertical as possible. If the steel rod is not perpendicular to the rock surface, the steel rod may slip while working. When crushing, first adjust the steel drill completely, and then select the impact point of the rock under stable conditions to perform the impact operation.
