Punch tonnage is one of the reasons for the impact of precision punching The main factors affecting the tonnage of precision presses include the length of the perimeter of the part hole punch for metal, the thickness of the material, and the strength of the material. Plate area and stroke length is determined by the size and depth of the parts shape, as the daily production capacity is mainly used to calculate the punch stroke per minute and the number of presses required to press the number of units in order to meet the overall production needs.

For this process, a short-stroke high-speed punching machine is required for the process of embryo-punching and punching. For the processes of molding and extension, it is necessary to use a process such as forming, stretching and the like to process the parts together Welding adjustable stand. Long stroke and slower punching presses are used in the process of stamping, embossing and embossing, etc. The short stroke punch with high energy is used at bottom dead center. Can be seen, the greater the punch press tonnage the higher the price, in this punch manufacturers to remind customers to buy punch when not blindly concerned about the price of punch CNC machine, and only choose their own punch is the best punch.

Precision punching bending processing generally use the A2-level punch, such as the accuracy of the workpiece, especially when the rebound is very strict requirements, the thickness allows a small error in the bending of phosphor bronze and other sheet metal parts, only the use of A1-level punch to achieve Required accuracy. Therefore, the workpiece material thickness of the different specifications than the punch is also important. Such as 2-level accuracy of the material in the bending when there is no problem on the accuracy of the case, the use of B2-level punch can get better results. However, such a sheet material sometimes mixed with thick and hard material, so that mold overload phenomenon, such as punch rigidity, may not produce deformation, but cause damage or deformation of the mold.
