对于要求严格的精密仪表圆柱螺旋弹簧和某些军用圆柱螺旋弹簧,在投产之前,首先要根据设计图纸的要求,进行工艺试验,即在弹簧机上进行试缠,以检验材料质量。并确定出弹簧抗力散布中心与产品图纸规定的检验抗力中心相重合的缠制参数,这样才能保证生产出的弹簧成品率最高。可是工艺试验是既费时又浪费材料的方法,因为在工艺试验中,要反复的改变缠制参数,有时即使经过大量的缠制,也得不到成品率高的缠制参数,而要依赖于加工工人的经验确定。对于精密弹簧的生产,是否可以去掉工艺试验,而通过电子计算机计算达到投产要求呢?本文就是给读者介绍一种用
For the demanding precision instrumentation cylindrical coil springs and some military cylindrical coil springs, before commissioning, the first according to the requirements of the design drawings, the process test, that is, the test on the spring machine wrapped to test the quality of the material. And determine the spring resistance distribution centers and product testing provisions of the test center of gravity coincide winding parameters, so as to ensure the highest yield of the spring produced. However, the process test is a time-consuming and wasteful method of material because in the process test, the winding parameters are repeatedly changed, sometimes even after a large amount of winding, the high-yielding winding parameters can not be obtained, The experience of processing workers to determine. For the production of precision springs, whether the process test can be removed, and calculated by the computer to put into operation requirements? This article is to introduce readers to a
