带限动器真空波纹管组件,其制造工艺较复杂,工序较多。因此本文要点简述如下: 一、波纹管制造工艺 1.管坯制备首先用板料冲杯,再经变径拉深及滚珠旋压变薄拉深后制成薄壁管,最后按要求切割成一定长度的管坯。本工序要保证管坏壁厚达到要求的精度。因为壁厚的变化对波纹管刚度的影响是很大的。由于壁厚误差ε_(ho)。存在而使波纹管位移产生的误差ε_w,可用公式计算:
Belt stopper vacuum bellows assembly, the manufacturing process is more complex, more processes. Therefore, the main points of this paper are summarized as follows: 1. Manufacturing Process of Bellows 1. Tube Blank First, the cup is made of sheet metal and then thinned by thinning and drawing with diameter reduction and ball spinning, and finally cut as required Into a certain length of the tube. This process to ensure that the pipe wall thickness to achieve the required accuracy. Because of changes in wall thickness of the bellows stiffness is great. Due to wall thickness error ε_ (ho). The existence of the error caused by the corrugated tube displacement ε_w, can be calculated using the formula:
