在毛主席革命路线指引下,在深揭猛批“四人帮”的大好形势推动下,我厂用冷挤压加工方法制造成功流线型切割喷咀,经切割试用,无论切割速度还是切口光洁度,效果都很好。如大型铸钢件,用流线型切割咀切割,比原来用车削提高工效8倍以上,质量完全合乎要求。现将我厂加工流线型切割咀(孔型如图1)的加工方法和切割效果简介如下。
Under the guidance of Chairman Mao’s revolutionary line and with the excellent situation of deeply criticizing and criticizing the “Gang of Four,” our factory has successfully manufactured streamlined cutting nozzles by means of cold extrusion. After cutting and testing, no matter the cutting speed or notch finish, well. Such as large castings, cutting with streamlined cutting Tsui, than the original use of turning to improve work efficiency more than 8 times, the quality completely in line with the requirements. Now I plant processing streamlined cutting Tsui (hole type Figure 1) processing methods and cutting results are as follows.
