用固态的橡胶、聚氨酯，液态的水、油及气态的压缩空气、膨胀气体等材料作为传力介质的板料半模成形工艺，促进了板料成形技术的发展。虽各自的特点构成了相应的适用范围，但亦存在着许多不足。本文通过对半模成形过程的研究，提出了一种新型的半模成形工艺──用粘塑性材料作为传力介质。通过对模具结构、板料成形性、产品的尺寸精度、表面质量及料厚均匀性等方面的研究分析表明，该工艺比气态、固态及液态材料为传力介质的半模成形工艺具有明显的优越性。通过对特形零件的试验成形表明，这种工艺方法具有广泛的应用前景。
The use of solid rubber, polyurethane, liquid water, oil and gaseous compressed air, expanding gas and other materials as the transmission medium sheet metal mold forming process, and promote the sheet metal forming technology. Although their respective characteristics constitute the corresponding scope of application, but there are also many deficiencies. Based on the research of the mold forming process, a new type of semi-mold forming process is proposed-using viscoplastic material as the transmission medium. Through the analysis of mold structure, sheet formability, product dimensional accuracy, surface quality and material thickness uniformity analysis shows that the process than the gaseous, solid and liquid materials for the transmission medium half-mold forming process has obvious Superiority. The test of special shaped parts shows that this method has a wide range of applications.
