Develops unceasingly along with the Chinese industry, the mold profession also appears more and more importantly. First has carried on the processing craft and the structure craft analysis to the processing components. Proposed through the computation semifinished materials size and the drawing coefficient four kind of plans, finally determined uses falls the material, the pro and con drawing superposable die. Has made the reasonable arrangement to the mold platoon type, enables the material use factor to achieve the high level. Has calculated each ramming craft strength which in the ramming process needs, including falls nearby the material strength, the ex-denning strength, the pressure the strength, the drawing strength, the top material strength and so on, and has carried on the reasonable tonnage primary election to the press. The superposable die has used the true thing form in the structure, calculated fell the material, the drawing and the counter- drawing effective range size. Closed has carried on the reasonable determination highly to the mold, but also designs the mold the major parts to fall the material concave mold, the convex-concave mold, the counter- drawing raised mold, the counter- drawing concave mold, the concave mold dead plate and so on. Listed the mold to need the components the detailed detailed list, and has produced the reasonable assembly drawing. Because the drawing depth is big, also carried on the power to the press electrical machinery to examine and to propose the lubrication attachment working procedure, could cause the drawing smoothly to complete. Finally led the wrap to mold major parts to carry on the simple processing craft route formulation. This design regarding uses the single acting press to carry on the pro and con drawing to have the certain reference function.
