本文指出:对于加工数量很少的大型工件,采用无模爆炸成型工艺是很经济的。试验初步结论是:先用圆片形药包爆炸成型,再用环形药包校形,其边皱长度约在板料直径的十分之一。当采用锥形药包时,初步试验表明:校形后可基本清除边皱现象。文章还给出了有关的经验公式。研究工作未涉及材料变薄率和大型工件各次成型之间的退火问题。 This paper points out: For the large number of small parts processing, the use of moldless explosion molding process is very economical. The preliminary conclusion of the experiment is as follows: the first round-shaped kits explosion molding, and then the ring kits school-shaped, the edge of the corrugated length of about one-tenth of the sheet diameter. When using conical kits, the preliminary test showed that: after the shape can be basically removed edge wrinkles. The article also gives the relevant empirical formula. The research work did not involve the problem of material thinning rate and the annealing between the various forming of large workpieces.
