EI-chip high-speed punch punching mold design of the nesting
Punching nesting is an important part of high-speed presses mold design, layout can not determine out punching, but also determines the material utilization and high-speed productivity.
Non-standard EI punching is the hub of the system of non-standard EI sheet, a sheet corresponding to an I-slice E, the more common nesting as shown, the material utilization rate is only 74 percent for large-scale production, material utilization slight increase , the economic benefits is very significant, and therefore improve material utilization as possible. Then there is no material utilization higher than this row like it, a careful analysis of EI sheet drawings, plus or minus about the size of a mobile combination arrangement, the two E sheet offset, as shown in nesting, material utilization rate of 85%. When comparing the two, improve material utilization * 1:20 * 2- nesting program and a 11 percent die in the size, shape and number of punch, difficult process and other aspects of essentially the same, that is to say the development cost of the mold no increase, while hedge sheet manufacturers, the economic benefits have been significantly by improved.
In the layout design, but also consider facilitating the punching leads. Imagine, four hundred times per minute speed punch, a four-piece mold (EI tablets each two pieces) If you can not successfully lead, out of all the sheets, by manual sorting, you simply can not do a one person on duty high-speed presses (operating presses, feeding, punching packing a person all inclusive) and therefore must lead by punching rack smoothly leads.
