制造弹簧时要压弹簧头。目的是使弹性均匀一致,以保证质量和图纸要求。我厂以前采用的办法有三种: (1)在铅罐内进行。先把铅加热到400～800℃,然后将弹簧按规定的圈数放入热铅溶液中,使弹簧受热而软化,拿出后加上压力,即可将弹簧头压平。但是直径比较小的弹簧,就不能按照本法在铅罐内进行加热。 (2)在酒精灯上加热,等弹簧头软化后加上压力即平。 (3)把一块鈇板烧红到400～800℃,再把弹簧端部放在鉄板平面上受热,等弹簧头软化后加上压力压平。
Spring pressure to make spring head. The goal is to make the elasticity uniform and consistent to ensure quality and drawing requirements. There are three ways I used the factory before: (1) Conducted within the lead tank. Lead the first heated to 400 ~ 800 ℃, and then the spring according to the provisions of the number of hot lead into the solution, so that the spring heat and softened, took out after the pressure, the spring can be flattened. However, the relatively small diameter of the spring, can not be in accordance with this law in the lead tank heating. (2) heating on the alcohol lamp, such as the spring head after softening the pressure that is flat. (3) Reduce the temperature to 400-800 ° C on a slab, place the end of the spring on a flat slab, and then apply heat to soften it.
