Background
With the development of the stamping industry, the stamping production is gradually transformed from a manual line to an automatic production line. From single-process equipment to continuous die production equipment to the existing multi-station production equipment. The development of a plurality of production processes of one device is gradually progressed from one production process of one device to the production processes of one device. Taking multi-station equipment as an example, all the working procedures of one stamping product can be produced on one piece of equipment, and one stamping stroke can be completed by the stamping equipment, so that a finished product can be produced. The process piece between each process is carried in an automatic mode, so that the production efficiency is greatly improved, the personnel quota is reduced, and the production cost is greatly reduced compared with the traditional production mode. However, since a plurality of processes are produced on the same equipment, the forming force required by each process is different, the condition that the stress of the sliding block on the equipment is uneven may exist, and the precision of the stamping equipment is reduced and the maintenance cost is increased when the stamping equipment is used for a long time in an unbalanced load manner. Therefore, before the development of the stamping die, the die positions of all the working procedures need to be reasonably arranged according to the offset load capacity of the equipment so as to meet the allowable offset load of the equipment. The existing punching equipment is temporarily provided with an unbalance load calculation method.
Based on the above description, the unbiased load calculation method is now temporary.
