螺母盒零件沖壓工藝與沖模設計 學生姓名：劉翔 班級：0781053 指導老師：陳為國 摘要：沖壓生產(chǎn)靠模具與設備完成加工過程，所以它的生產(chǎn)率高，而且由于操作簡便，也便于實現(xiàn)機械化和自動化。 沖壓產(chǎn)品的尺寸精度是由模具保證的，所以質(zhì)量穩(wěn)定，一般不需再經(jīng)過機械加工便可使用。 沖壓加工一般不需要加熱毛坯，也不像切割加工那樣大量切削材料，所以它不但節(jié)能，而且節(jié)約材料。沖壓產(chǎn)品的表面質(zhì)量較好，使用的原材料是冶金工廠大量生產(chǎn)的軋制板料或帶料，在沖壓過程中材料表面不受破壞。 因此，沖壓工藝是一種產(chǎn)品質(zhì)量較好而且成本低的加工工藝。用它生產(chǎn)的產(chǎn)品一般還具有重量輕且剛性好的特點。 關鍵詞：沖壓模具 沖壓工藝 模具設計 指導老師簽名： Nut box parts stamping process and die design Student name:Liu xiang Class: 0781053 Supervisor:Chen wei guo Abstrct: Blunt press to produce to be processed process by molding tool and equipments completion, so it of rate of production Gao, and because of operation simple, also easy to realization mechanization and automation. Blunt press the size accuracy of product is promise by the molding tool of, so quality stable, generally doing not need to through machine process again then can use. Blunt press to process generally don't need to heat semi-finished product, also be unlike to incise to process to so and in great quantities slice to pare material, so it not only economizes on energy, but also economize material.Blunt press the surface quality of product better, the original material of usage is a metallurgy factory mass production of the Ya system plank anticipate or take to anticipate and the material surface is free from breakage in bluntly ran over the distance. Therefore, it ising blunt to press a craft be a kind of product quality better and the cost lowly process a craft.Use the product that it produce generally still has the weight light and rigid and good characteristics.
