(4) the structure of the die is irrational, the carrying capacity per unit area caused by poor die easily lead to cracking failure. Figure 1 Analysis in Loop fins mask open-shaped crack repair mode for variable-frequency solutions to difficult 3 After a complicated analysis of the causes, the causes that affect us,mulberry oslo, take the following 3.1 Au forging solutions for quality control posite materials and material thickness requirements (according to material thickness under normal circumstances 15% to 20% discharge gap). Punch and die cavity can not research the taper repair,abercrombie et fitch, maintenance and research as easy to play the material when the inverted cone, repair and photometric study of differential geometry, it will increase the radial force of the mold, more than the material strength limit,mulberry sverige, led to cracking failure, can reduce the impact by amending the study to improve the die life; and assembly to ensure that the gap even, convex molding people to ensure the vertical plywood, fasteners should be solid and reliable, especially when the assembly to ensure uniform convex space, the gap will be offset bite wound edge, increased wear of the mold, the mold is very unfavorable to life. 4 Comparative Analysis before and after reconstruction (1) after the implementation of the batch by modifying the number of greatly increased, basically the number of the original batch of 10 times,ed hardy kleider, through life survey can be seen in Table 2. Table 2 Life questionnaire parameters control the number of tryout crack cases the number of repair quantities of quality of life good or bad repair structural material 2 or 3 times out 200-500 films are hard to crack difference between 2000 and 5000 and even more structural material transformation Yam modified times were 2000 to 5000 Ming-crack 20000 ~ 50000 Easy good condition, the split die combination of the strength of monolithic die is about 1.3 times. Indicate the specific structure shown in Figure 3. After the transformation diagram in Figure 3 (2) benefit assessment in 2003 cost savings per million -31 726 yuan to 26,078 yuan, through effective assessment can be seen in Table 3. Table 3 Benefit Assessment Form parameters of each mold to be cost per million tryout fee per million per million repair cost cost (redundant) with the number of control modules sets of costs (redundancy) (Wu) (L) 5 vertical × f2 ~ 3J times × l6x175 Organisation × 50H × l7 = 4250 transformation of the former 300xl7 = 5l Midship 5-62.55 3. {) 60000 = 2720-4080fl a 2) × l × 16 × l7l set to change × 5OH × 17 = 850, after making Mrs. 3l0xI7 = 5271l15270 = 272-5443.5 bench repair and assembly of research to improve the die life of fan films blanking die punch either die or must be revised in the finishing stages of research, general requirements V7 a V8. Work surface brightness difference in the thermal shock, it will increase the punching power, and in severe injury nap mold, increasing die wear, so reduce the life of the mold, it is necessary repair work of research to improve the surface brightness; it is necessary to ensure that the surface roughness, but also to ensure a reasonable gap and the mold surface geometry. The die and punch through the gap to break 5 Conclusions and in the actual production test users show that blanking die to solve the main problem areas mentioned above, not only can reduce costs, reduce the cost of test mode, and the repair cycle of mold significantly reduced.
