为了革新产品和工艺,改善模具、润滑材料和机器的工作效能,开发更好的锻件材料和模具材料,通过不断的、积极的努力,冷模锻的应用范围在近期内成功而极其明显地得到了扩大。采用冲挤法,除了材料消耗较少外,由于加工精度高,可以省去锻件的切削加工,大大节约了费用。近几年来,冷模锻的主要目标是,能生产出尺寸与形状精度高和表面质量好的,并能承受高机械负荷的锻件。横向冲挤件可以不经过或少经过机械加工而成为成品,而且其使用性能也得到了提高。因此,横向冲挤法获得了新的应用可能性;该法不仅在扩大可以生产的锻件形状的范围方面,而且在生产尺
In order to innovate products and processes, improve the working efficiency of molds, lubricants and machines and to develop better forgings and mold materials, the range of applications of cold forging has been achieved with great success in the near future with constant and positive efforts Expanded. Extrusion method, in addition to less material consumption, due to high precision machining, you can save the forging machining, significant cost savings. In recent years, the main goal of cold forging is to produce forgings with high dimensional and shape accuracy and good surface quality, which can withstand high mechanical loads. Horizontal extrusion can be less or less through the machining and become the finished product, and its performance has also been improved. As a result, a new possibility of application is obtained by lateral extrusion; this method not only expands the range of shapes forgings that can be produced,
