用冷拔彈簧鋼絲制造緊縮螺旋彈簧
Manufacture of Compact Coil Spring with Cold Drawn Spring Steel Wire
用冷拔彈簧鋼絲制造緊縮螺旋彈簧的基本工藝流程。其中,虛線框中的工序為非固定工序,能否中止取決於彈簧的性能懇求和消費廠的客觀條件。
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.
關於車床卷簧,在卷簧工序後須經切斷工序,把壹次卷成的幾個連在壹同的彈簧分別成單個彈簧。有些重要的彈簧,在磨削端面之前,可增加壹道毛坯高度分類工序,以保證磨削質量。也可將磨削工序分為粗磨和精唐兩道工序,並在粗磨後中止去毛刺或倒角
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.
用冷拔彈簧鋼絲制造拉伸螺旋彈簧拉伸螺旋彈簧的制造,國外已有特地的自動卷簧機,關於壹些典型鉤環,可以在卷簧工序壹次完成。但是,在國內,目前尚未消費這種機床。拉伸彈簧鉤環是用壹些專用模具來制造,是壹道特地工序。
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,卷簧後的去應力回火工序是消弭卷繞過程中產生的剩余應力,而鉤環制造後的回火工序,則是為了消弭制造鉤環時產生的內應力。固然這兩道工序都有消弭內應力的作用,但不能兼並為壹道工序,由於前壹道回火工序兼有定形作用,以確保鉤環的相對位置精度。並且後壹道回火工序的加熱溫度壹定不能高於前壹道的回火溫度。
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.
不象緊縮彈簧
Unlike a compact spring
拉伸彈簧普通不中止強拉處置。由於丸粒難於噴到彈簧內表面,故也不中止噴丸處置
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.
用冷拔彈簧鋼絲制造改動螺旋彈簧與拉伸彈簧類似,改動螺旋彈簧的制造,國外也有特地的自動卷簧機,關於壹些典型扭臂,可以在卷簧工序壹次完成。但是,國內目前只需直尾卷簧機,扭臂必需用特地的模具,在特地的工序上完成。
電腦彈簧機
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,國內消費改動螺旋彈簧的典型工藝流程有兩種,壹種是先定尺下料,然後再中止卷簧等其它工序,如雙臂扭簧的工藝流就屬此例(圖5-12);另壹種是類似拉簧的工藝流程,只是不同於:拉簧是制造鉤環,而扭簧則是制造扭臂
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.
由於在卷簧時產生的剩余應力與工作應力的方向相反,所以也經常省略回火工序,以讓這些有益的剩余應力削減工作應力的峰值。但是回火處置有利於使彈簧材料的晶粒結構穩定,並可減少彈簧扭臂在運輸等過程中因碰撞而惹起的變形。
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.
強扭處置也是對極少數特殊扭簧而布置的工序。
Strong torsion disposal is also a process for arranging a few special torsion springs.
用退火狀態供應的彈簧鋼絲制造螺旋彈簧
Manufacture of Spiral Spring with Spring Steel Wire Supply in Annealing State
退火狀態供應的合金彈簧鋼絲主要用來制造緊縮螺旋彈簧,它的工藝流程與上述不同的主要是成型後要中止淬火、回火處置,制造彈簧端部時而需經正火處置,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.
熱卷大彈簧的工藝流程
Process Flow of Hot Coil Spring
材料直徑大於12mm的彈簧,常稱為大彈簧,普通是用熱成型方法制造。熱卷大彈簧基本上是緊縮螺旋彈簧,其基本工藝流程見圖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.
熱卷彈簧都是有芯卷簧。關於卷制圓錐螺旋緊縮彈簧,由於在卷制時開檔(卷出節距來)困難,故在校正工序中,兼有開檔的任務。另外,為保證淬火溫度,校正工序壹定要動作準確疾速。否則,淬火時必需重新加熱。為進步熱卷彈簧的疲倦壽命,有條件時,應盡可能中止。
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.
