【 摘 要 】

New methods of sheet stamping were developed: the gas forming with double-sided heating of a blank part and the gas molding with backpressure. In case of the first method the blank part is heated to the set temperature by means of a double-sided impact of combustion products of gas mixtures, after which, under the influence of gas pressure a stamping process is performed. In case of gas molding with backpressure, the blank part is heated to the set temperature by one-sided impact of the combustion products, while backpressure is created on the opposite side of the blank part by compressed air. In both methods the deformation takes place in the temperature range of warm or hot treatment due to the heating of a blank part. This allows one to form parts of complicated shape within one technological operation, which significantly reduces the cost of production. To implement these methods, original devices were designed and produced, which are new types of forging and stamping equipment. Using these devices, an experimental research on the stamping process was carried out and high-quality parts were obtained, which makes it possible to recommend the developed methods of stamping in the industrial production. Their application in small-scale production will allow one to reduce the cost price of stamped parts 2 or 3 times.
