When making claw hammer manufacturers, they need to pay attention to cutting steel, two perpendicular, two in place, one direction, and repair the two ends of the steel until the two ends are smooth, and ensure that the file is perpendicular to the circumference of the cylinder.
As for the heat treatment of the claw hammer, it includes three processes: heating, heat preservation and cooling. Under normal circumstances, these three processes are connected with each other and cannot be interrupted. It can be roughly divided into direct heating and indirect heating. Charcoal, coal, liquid and gas fuels, and electric heating are direct heating; molten salt or metal or even floating particles can be used for indirect heating.
When heating, the claw hammer is exposed to the air, and oxidation and decarburization often occur. This has a very negative effect on the surface properties of the parts after heat treatment. Therefore, we must pay attention to the method to enhance the performance of the product.
