用冷拔弹簧钢丝制造紧缩螺旋弹簧
Manufacture of Compact Coil Spring with Cold Drawn Spring Steel Wire
用冷拔弹簧钢丝制造紧缩螺旋弹簧的基本工艺流程。其中,虚线框中的工序为非固定工序,能否中止取决于弹簧的性能恳求和消费厂的客观条件。
The basic technological process of manufacturing compact coil spring with cold-drawn spring steel wire. Among them, the process in the dashed wire frame is a non-fixed process. Whether it can stop depends on the performance of the spring and the objective conditions of the consumer factory.
关于车床卷簧,在卷簧工序后须经切断工序,把一次卷成的几个连在一同的弹簧分别成单个弹簧。有些重要的弹簧,在磨削端面之前,可增加一道毛坯高度分类工序,以保证磨削质量。也可将磨削工序分为粗磨和精唐两道工序,并在粗磨后中止去毛刺或倒角
Regarding lathe coiling spring, after coiling spring process, several coiling springs are separated into single springs through cutting process. Some important springs, before grinding the end face, can add a rough height classification process to ensure the grinding quality. The grinding process can also be divided into two parts: rough grinding and fine grinding, and the deburring or chamfering can be stopped after rough grinding.
用冷拔弹簧钢丝制造拉伸螺旋弹簧拉伸螺旋弹簧的制造,国外已有特地的自动卷簧机,关于一些典型钩环,可以在卷簧工序一次完成。但是,在国内,目前尚未消费这种机床。拉伸弹簧钩环是用一些专用模具来制造,是一道特地工序。
The manufacture of stretching coil spring with cold-drawn spring steel wire has special automatic spring coiling machine abroad. For some typical hook rings, the coiling process can be completed at one time. However, at present, this kind of machine tool has not been consumed in China. The tension spring hook and ring is manufactured by some special moulds, which is a special process.
值得留意的是,卷簧后的去应力回火工序是消弭卷绕过程中产生的剩余应力,而钩环制造后的回火工序,则是为了消弭制造钩环时产生的内应力。固然这两道工序都有消弭内应力的作用,但不能兼并为一道工序,由于前一道回火工序兼有定形作用,以确保钩环的相对位置精度。并且后一道回火工序的加热温度一定不能高于前一道的回火温度。
It is worth noting that the stress relief tempering process after coiling spring is to eliminate the residual stress generated during the winding process, while the tempering process after hook ring manufacturing is to eliminate the internal stress generated during the manufacturing of hook ring. Although these two processes have the function of eliminating internal stress, they can not be merged into one process, because the former tempering process has both setting effect to ensure the relative position accuracy of the hook ring. And the heating temperature of the latter tempering process must not be higher than that of the former.
不象紧缩弹簧
Unlike a compact spring
拉伸弹簧普通不中止强拉处置。由于丸粒难于喷到弹簧内表面,故也不中止喷丸处置
The tension spring usually does not stop the tension disposal. Because it is difficult for pellets to be sprayed on the inner surface of springs, the disposal of pellets is not stopped.
用冷拔弹簧钢丝制造改动螺旋弹簧与拉伸弹簧类似,改动螺旋弹簧的制造,国外也有特地的自动卷簧机,关于一些典型扭臂,可以在卷簧工序一次完成。但是,国内目前只需直尾卷簧机,扭臂必需用特地的模具,在特地的工序上完成。
电脑弹簧机
The manufacture of modified coil spring with cold-drawn spring steel wire is similar to that of tension spring. The manufacture of modified coil spring has special automatic coiling machine abroad. For some typical torsion arms, the coiling process can be completed at one time. However, at present, only the straight-tail spring coiler is needed in our country, and the torsion arm must be completed by special die in special working procedure.
目前,国内消费改动螺旋弹簧的典型工艺流程有两种,一种是先定尺下料,然后再中止卷簧等其它工序,如双臂扭簧的工艺流就属此例(图5-12);另一种是类似拉簧的工艺流程,只是不同于:拉簧是制造钩环,而扭簧则是制造扭臂
At present, there are two typical technological processes for domestic consumption to change coil spring, one is to cut the coil spring at a fixed length, and then stop the coil spring and other processes, such as the process flow of double-arm torsion spring, which belongs to this example (Fig. 5-12); the other is similar to the process flow of pull spring, except that the pull spring is the manufacture of hook rings, while the torsion spring is the manufacture of torsion arms.
由于在卷簧时产生的剩余应力与工作应力的方向相反,所以也经常省略回火工序,以让这些有益的剩余应力削减工作应力的峰值。但是回火处置有利于使弹簧材料的晶粒结构稳定,并可减少弹簧扭臂在运输等过程中因碰撞而惹起的变形。
Because the residual stress produced in the coiling spring is opposite to the direction of the working stress, the tempering process is often omitted so that these beneficial residual stresses can reduce the peak value of the working stress. However, tempering treatment can help to stabilize the grain structure of spring material and reduce the deformation caused by collision during the transportation of spring torsion arm.
强扭处置也是对极少数特殊扭簧而布置的工序。
Strong torsion disposal is also a process for arranging a few special torsion springs.
用退火状态供应的弹簧钢丝制造螺旋弹簧
Manufacture of Spiral Spring with Spring Steel Wire Supply in Annealing State
退火状态供应的合金弹簧钢丝主要用来制造紧缩螺旋弹簧,它的工艺流程与上述不同的主要是成型后要中止淬火、回火处置,制造弹簧端部时而需经正火处置,其它工序基本相同。
The alloy spring steel wire supplied in annealing state is mainly used to manufacture the compact coil spring. Its technological process is different from that mentioned above. The quenching and tempering should be stopped after forming. The end of the spring should be normalized while manufacturing. The other processes are basically the same.
热卷大弹簧的工艺流程
Process Flow of Hot Coil Spring
材料直径大于12mm的弹簧,常称为大弹簧,普通是用热成型方法制造。热卷大弹簧基本上是紧缩螺旋弹簧,其基本工艺流程见图5-14。
Springs with material diameter greater than 12 mm are often called large springs, which are usually manufactured by thermoforming method. The large hot coil spring is basically a compact coil spring. Its basic technological process is shown in Fig. 5-14.
热卷弹簧都是有芯卷簧。关于卷制圆锥螺旋紧缩弹簧,由于在卷制时开档(卷出节距来)困难,故在校正工序中,兼有开档的任务。另外,为保证淬火温度,校正工序一定要动作准确疾速。否则,淬火时必需重新加热。为进步热卷弹簧的疲倦寿命,有条件时,应尽可能中止。
Hot coil springs are all cored coil springs. As for the tapered helical contraction spring, it is difficult to open the gear (roll out the pitch) during the winding process, so the task of opening the gear is also included in the correction process. In addition, in order to ensure quenching temperature, the correction process must be accurate and fast. Otherwise, it must be reheated during quenching. In order to improve the fatigue life of hot coil spring, it should be stopped as far as possible when conditions permit.
