怎么区别优质弹簧?

首先,电池弹簧的设计要安全,弹簧的开口处必须内弯,不能伤手.产品做出来是为了帮顾客解决问题享受生活的.,所以安全一
First of all, the design of the battery spring should be safe. The opening of the spring must be bent inward and can't hurt hands. The product is made to help customers solve problems and enjoy life, so safety is a must
第二,电池弹簧的导电性要好.要求一般的弹簧应该是碳钢线做成的弹簧我,再做电镀处理.而电镀也是要先镀铜底,再底镍的.要求做盐雾测试少是5%达24小时.要求导电性高的表面则镀金,银,锡等.弹簧材料也可选用铜线,当然铜线的弹性没有碳钢好
Second, the conductivity of the battery spring is better. It is required that the general spring should be made of carbon steel wire and then electroplated. The electroplating also needs to be plated with copper and then nickel. The salt spray test is required to be less than 5% for 24 hours. The surfaces with high conductivity are plated with gold, silver, tin, etc. the spring material can also be copper wire. Of course, the elasticity of copper wire is not as good as that of carbon steel
第三就是弹簧的结构要合理,对安装的稳固性要考虑周全.电池弹簧接触电池的中心点要对准.电池弹簧接触电池的地方也不能太大.太大容易正极和负极连接,造成短路.
The third is that the structure of the spring should be reasonable and the stability of installation should be considered comprehensively. The center point of the battery spring contacting the battery should be aligned. The place where the battery spring contacts the battery should not be too large. Too large is easy to connect the positive and negative electrodes, resulting in a short circuit
第四点就是生产包装要注意的问题了.为了方便生产.弹簧厂家的弹簧包装必须便于生产线生产.由于电池弹簧大多是成螺旋状,而且弯钩多.容易纠结在一起不容易分开,影响生产速度,所以建设用吸塑盒包装或少数量包装
The fourth point is to pay attention to the production and packaging. In order to facilitate production, the spring packaging of spring manufacturers must be convenient for the production line. Because most battery springs are spiral and have many hooks, they are easy to tangle together and not easy to separate, affecting the production speed, so they are packed in blister boxes or in a small number for construction

弹簧选材原则
Spring material selection principle
首先满足功能要求,其次是强度要求,后才考虑经济性。
First meet the functional requirements, followed by the strength requirements, and then consider the economy.
碳素弹簧钢是弹簧钢中用途广泛,用量大的钢类。钢中含0.60%~0.90%的碳和0.3%~1.20%的锰,不再添加其它合金元素,使用成本相对较低。碳素弹簧钢丝经适当的加工或热处理,可以获得很高的抗拉强度,足够的韧性和良好的疲劳寿命。但碳素钢丝的淬透性低,抗松弛性能和耐蚀性能差,弹性模量的温度系数较大(高达300×10-6/℃),适用于制造截面较小,工作温度较低(120℃>)的弹簧。
Carbon spring steel is a kind of steel widely used and used in spring steel. The steel contains 0.60% ~ 0.90% carbon and 0.3% ~ 1.20% manganese, no other alloy elements are added, and the service cost is relatively low. After proper processing or heat treatment, carbon spring steel wire can obtain high tensile strength, sufficient toughness and good fatigue life. However, carbon steel wire has low hardenability, poor relaxation resistance and corrosion resistance, and the temperature coefficient of elastic modulus is large (up to 300) × 10-6 / ℃), suitable for manufacturing springs with small section and low working temperature (120 ℃ & gt;).
合金弹簧钢一般含0.45%~0.70%的碳和一定量的Si,Mn,Cr,V,W及B等合金元素。合金元素的加入改善弹簧钢的抗松弛性能,提高钢的韧性,同时显著提高钢的淬透性和使用温度,适用于制造较大截面,较高温度下使用的弹簧。
Alloy spring steel generally contains 0.45% ~ 0.70% carbon and a certain amount of Si, Mn, Cr, V, W, B and other alloy elements. The addition of alloy elements improves the relaxation resistance of spring steel, improves the toughness of steel, and significantly improves the hardenability and service temperature of steel. It is suitable for manufacturing springs with large section and high temperature.
