The correct choice and reasonable use of stamping equipment will determine whether stamping production can be carried out smoothly, and is closely related to product quality, die life, production efficiency and product cost.
The choice of stamping equipment is mainly based on stamping process properties, production volume size, stamping parts of the geometric shape, size and precision requirements to determine the factors. There are many kinds of stamping equipment commonly used in stamping production. The following factors should be considered when selecting stamping equipment:
Whether the type and working form of stamping equipment are suitable for the process to be completed, and whether they meet the requirements of safe production and environmental protection. For blanking process, medium and small blanking parts usually choose open crank press; Large, medium and precision blanking parts, generally choose closed crank press; Fine blanking adopts special dynamic press or press machine with hydraulic die frame. Hydraulic machine due to slow speed, low efficiency, and at the end of the punching, suddenly unloaded will produce impact vibration, so generally not be chose in the punching process.
Whether the pressure and power of the stamping equipment meet the requirements of the completed process.
Whether the molding height, worktable size and stroke of the stamping equipment are suitable for the die used in the process.
Whether the stroke times of stamping equipment meet the requirements of production efficiency.
