某产品中的牛角导管(外观见图1),是一个型面比较复杂精度要求比较高的零件。其技术要求如下: 1.零件的外型与样板间隙不大于0.5~2毫米; 2.空间曲面要求圆滑过渡,不得有突转和凹陷; 3.进口和出口尺寸、位置要与相对应的零件协调; 4.零件材料为1Cr18Ni9Ti不锈钢板,厚2毫米,材料减薄不得小于1.6毫米。
A product of the horns catheter (appearance shown in Figure 1), is a profile more complex parts of the higher precision requirements. The technical requirements are as follows: 1. Parts of the shape and model clearance of not more than 0.5 to 2 mm; 2. Space surface requires a smooth transition, without a sudden and depression; 3. Import and export size, location and the corresponding parts Coordination; 4. Parts of the material 1Cr18Ni9Ti stainless steel, 2 mm thick, material thinning not less than 1.6 mm.
