扭转弹簧产品的基础信息内容
文章来源:http://www.sdzbthc.com/ 发布时间:2022-05-17 浏览次数:
扭转弹簧是一种利用弹性来工作的机械零件,一般用弹簧钢制成。用以控制机件的运动、缓和冲击或震动、贮蓄能量、测量力的大小等广泛应用于计算机,电子,家电,照相机,仪器,门,摩托车,收割机,汽车,等行业!下面来讲讲扭转弹簧产品的基础信息内容吧。
Torsion spring is a kind of mechanical part that uses elasticity to work. It is generally made of spring steel. It is widely used in computer, electronics, home appliances, cameras, instruments, doors, motorcycles, harvesters, automobiles, and other industries to control the movement of parts, mitigate impact or vibration, store energy, measure the size of force, etc! Let's talk about the basic information of torsion spring products.
扭转弹簧是由弹簧钢制成的、有扭曲弹性的杆。如果用手拧根橡皮棒,使它扭曲,它会扭转固定角度,人们也会感到它的弹力。当放松时,它就会恢复原状。利用这个原理,就可利用金属扭转弹簧来作为汽车悬架的弹性元件。
Torsion spring is a rod made of spring steel with torsion elasticity. If you twist a rubber stick by hand, it will twist a fixed angle and people will feel its elasticity. When relaxed, it will return to its original state. Using this principle, the metal torsion spring can be used as the elastic element of automobile suspension.
弹簧的两边,固定在车架或车身上;固定在悬架的摆臂上并与车轮相连。车轮跳动时,摆臂使扭杆弹簧发生扭转变形,储存能量,起到弹性元件的作用。断面通常是圆形或管形,少数为矩形。还有的为了使弹簧柔软,采用多层扭片的组合断面。属性是结构简单,占用空间小,适用于小型汽车。缺点是刚度受到扭杆长度的限制,不够柔软,乘坐舒适性不理想。
Both sides of the spring are fixed on the frame or vehicle body; It is fixed on the swing arm of the suspension and connected with the wheel. When the wheel jumps, the swing arm makes the torsion bar spring twist and deform, stores energy and acts as an elastic element. The section is usually circular or tubular, and a few are rectangular. In addition, in order to make the spring soft, the combined section of multi-layer torsion sheet is adopted. The attribute is simple structure and small space, which is suitable for small cars. The disadvantage is that the stiffness is limited by the length of the torsion bar, which is not soft enough and the ride comfort is not ideal.
扭簧用法应避免超过最大扭转量的使用扭力产生进而造成折损,接近密著长之使用,会使弹簧线部逐渐密著如此,因为弹簧定数变高造成荷重曲线随之生高,近而产生高应力使弹簧失效。
The usage of torsion spring should avoid the use of torsion exceeding the maximum torsion, which will cause damage. The use close to the dense length will gradually close the spring line. This is because the higher the fixed number of spring, the higher the load curve, and the higher the near stress will cause the spring to fail.
弹簧扭转的时候材料是拉伸或者剪切状态比如谈到的扭转度计算,因此这个可扭转的角度限制最后是因为材料的失效而造成的,当材料发生塑性变形时无法恢复原来状态。因此归结为材料的抗拉强度跟抗剪强度,当然用第四强度理论计算得到的VonMises应力为材料可承受的很大强度,结合弹簧的长度,便可以计算出很大允许扭转角度。
When the spring is twisted, the material is in tension or shear state. For example, when it comes to the calculation of torsion degree, this torsional angle limit is finally caused by the failure of the material. When the material is plastically deformed, it cannot return to its original state. Therefore, it comes down to the tensile strength and shear strength of the material. Of course, the von Mises stress calculated by the fourth strength theory is the great strength that the material can bear. Combined with the length of the spring, a large allowable torsion angle can be calculated.
弹簧加工工艺非常的复杂有讲究,我们需要掌握一定的知识才能更好的生产出优质的弹簧来,尤其是关于弹簧加工过程中所需要注意的问题,我们一定要清楚,因为这和后续生产制作和产品质量上是有非常大影响的,比如:
The spring processing technology is very complex and exquisite. We need to master certain knowledge to better produce high-quality springs. In particular, we must be clear about the problems needing attention in the spring processing process, because it has a great impact on the subsequent production and product quality, such as:
支承圈根据产品要求可选用冷并和热并两种方法。采用热并方式不允许将簧加热至打火花或发白,硅锰钢温度不得高于850℃。支承圈与有效圈应有效接触,间隙不得超过圈间公称间隙的10%。
According to the product requirements, the support ring can be cold combined and hot combined. It is not allowed to heat the spring to spark or whiten by heating, and the temperature of silicon manganese steel shall not be higher than 850 ℃. The bearing ring shall be in effective contact with the effective ring, and the gap shall not exceed 10% of the nominal gap between the rings.

多股簧特性可由调整导程决定,绕制时索距可进行必要调整。拧距可取3~14倍钢丝直径,但一般取8~13倍为佳。其簧力还与自由高度、并端圈、外径及钢丝性能等有密切关系,可通过调整其中某项或几项予以改变。
The characteristics of multi strand spring can be determined by adjusting the lead, and the cable distance can be adjusted when winding. The screw pitch can be 3 ~ 14 times of the steel wire diameter, but generally 8 ~ 13 times is preferred. The spring force is also closely related to the free height, parallel end ring, outer diameter and steel wire performance, which can be changed by adjusting one or more of them.
重要弹簧紧压时间为24小时,普通弹簧为6小时或连续压缩3~5次,每次保持3~5秒。紧压时弹簧与芯轴的间隙以芯轴直径的10%为宜,间隙过小则难于操作,间隙过大则易使弹簧发生弯曲变形。紧压时若其中一件弹簧折断,则其余应重新处理。
The tightening time of important springs is 24 hours, while that of ordinary springs is 6 hours or continuously compressed for 3 ~ 5 times, holding for 3 ~ 5 seconds each time. When pressing, the gap between the spring and the mandrel should be 10% of the mandrel diameter. If the gap is too small, it is difficult to operate, and if the gap is too large, it is easy to bend and deform the spring. If one of the springs is broken during tightening, the rest shall be reprocessed.
弹簧表面处理一般进行磷化处理即可,也可进行其它处理。凡要进行镀层为锌与镉时,电镀后应进行除氢处理,除氢后抽3%(不少于3件)复试立定处理,复试中不得有断裂。弹簧应清除表面脏物、盐痕、氧化皮,方法可采用吹砂或汽油清洗的办法,但不能采用酸洗。
Generally, the spring surface can be treated with phosphating or other treatments. Where the coating is zinc and cadmium, hydrogen removal treatment shall be carried out after electroplating. After hydrogen removal, 3% (not less than 3 pieces) shall be sampled for retest and standing treatment. There shall be no fracture in the retest. The surface dirt, salt mark and oxide scale of the spring shall be removed. The method can be sand blowing or gasoline cleaning, but pickling cannot be used.
