The thread rolling machine is a metal tool with a certain pressure. It is a process that uses a thread rolling wheel to roll the workpiece to remove burrs and grooves on the surface of the workpiece. Thread rolling machines can generally be divided into CNC thread rolling machines, wire cutting thread rolling machines, vertical thread rolling machines and horizontal thread rolling machines. Because the precision of rolling is higher than that of cutting, it is widely used in machinery manufacturing, especially in the production of mechanical parts.
For workpieces of different materials, the pressure during rolling processing will be different. It is necessary to select different rolling pressures according to the material of the workpiece and the depth of rolling to meet the requirements of the workpiece. The pressure during rolling is determined according to the roughness requirements of the surface of the workpiece after thread rolling, and the friction between the rolling wheel and the workpiece must also be considered, which requires an analysis of the material and process of the workpiece.
For example: steel, aluminum, copper, stainless steel, etc. When rolling, it is necessary to pay attention to the pressure not to be too large, otherwise it will cause deformation of the thread rolling wheel and cause damage to the workpiece. In addition, the pressure should be determined according to the depth of rolling. If it is too small, a good rolling effect cannot be achieved, and if it is too large, it will damage the workpiece.
When the surface roughness of the workpiece is required to be high, the greater the rolling depth, the better. At this time, it is necessary to increase the rolling speed. The rolling pressure is small, the rolling depth is large, and the surface roughness of the workpiece will also become poor.
In general, the depth of rolling processing should be proportional to the diameter of the rolling wheel. If the diameter of the rolling wheel is the same, a smaller rolling pressure should be selected. When the surface roughness of the workpiece is required to be high, the greater the rolling depth, the better. At this time, it is necessary to increase the rolling speed. The rolling pressure is small, the rolling depth is large, and the surface roughness of the workpiece will also become poor.
