Selection of stamping equipment The stamping work is to install the stamping die on the stamping equipment, so the design of the die should match the type and main specifications of the stamping equipment, otherwise it will not work. (1) For small and medium-sized blanking parts, bending parts or drawing parts, open mechanical presses are mainly used. However, the open mechanical press is still the main equipment for producing small and medium-sized stamping parts because it provides extremely convenient operating conditions and simple installation of mechanized accessories. Moreover, under the action of large stamping pressure, the deformation of the machine body will change the gap distribution of stamping dies and reduce the life of dies and the surface quality of stamping parts. (2) Large and medium-sized stamping parts mostly use closed mechanical presses, including general presses and special precision presses, double-acting or triple-acting stretching presses, etc. Among them, the precision press with high precision and rigidity should be selected for sheet blanking or precision blanking; When producing large-scale complex drawing parts, double-acting or triple-acting drawing machines should be selected as far as possible, which can make the die structure simple and easy to adjust. (3) In small batch production, hydraulic press or friction press are mostly used. Hydraulic press has no fixed stroke, and will not be overloaded due to the change of plate thickness. When a large force stroke is needed, it has obvious advantages over mechanical press.
