2.1.5 Calculation method of force in cold heading process
2.1.5.1 Cold heading force
Cold heading force is the main basis for determining process parameters, designing molds, designing cold heading machines, and selecting specialized equipment.
There are many factors that determine the magnitude of cold heading force, mainly including the following aspects:
a. Mechanical properties of metals
The cold heading force increases with the increase of material strength and hardness.
b. Shape and degree of deformation of the workpiece
The cold heading force increases with the increase of workpiece deformation.
c. Friction
Due to the frictional force on the contact surface between the mold and the workpiece, the direction and magnitude of the force are changed to varying degrees, thereby affecting the cold heading force.
d. Mold shape
The different shapes of molds and dies cause differences in the flow resistance of metal in various directions, thereby affecting the cold heading force.
