Metal stamping pieces of multistep progressive dies how much do you know?
General hardware stamping die mold points have single working procedure and multi-station progressive dies, in the actual production process in order to improve the work efficiency and reduce the product cost, we can adopt the multi-station progressive dies to complete the production, the work of hardware stamping progressive dies steps is simplex mold the sum of the decomposition process, under the condition of the die strength is not affected, we work steps with as little as possible, less work steps are cumulative error is less, the higher the precision metal stamping parts;
High dimensional accuracy requirements of metal stamping parts of the work steps should try to arrange at the end of the process, the work of the accuracy is not high step can be arranged in front of the process, as the top the cumulative work step, the greater the error accumulation;
In multi-station progressive dies, punching, incision and forming process to arrange order, the general is to arrange separation process in front (
Such as punching, incision, etc. )
, then can arrange forming, deep drawing process, the last in the arrangement of cutting and blanking process;
In the design of hardware stamping mould, if the forming and blanking on the same die, try not to design in the same fixed plate, the general forming punch fixed on the take off board, make each work step forming parts from being damaged, is expected to remain in the same feed line.
Multiplex step hardware stamping progressive dies to have adjustable guide pin, the semicircle incision, interface can be recommended for process more metal stamping products, die should be adopted as far as possible into the block structure, can realize quick replacement and repair.
