优化压缩弹簧的质量有几个妙招

压缩弹簧是现在生产和生活上必备的物品,那么你知道优化压缩弹簧的质量怎么办吗?其实影响压缩弹簧生产质量的因素大致可以分为:拉拔工艺、生产组织以及设备原因。
Compression spring is a necessary item in production and life. Do you know how to optimize the quality of compression spring? In fact, the factors affecting the production quality of compression spring can be roughly divided into: drawing process, production organization and equipment reasons.
在一定条件下,应保持总压缩率不变,适当降低局部压缩率,适当增加拉伸次数,特别是可以改变压缩后的局部压缩率。钢丝的内应力分布状态使抗拉强度不断下降,塑性指标增加,产品合格率将大大提高。
Under certain conditions, the total compression ratio should be kept unchanged, the local compression ratio should be appropriately reduced, and the stretching times should be appropriately increased, especially the local compression ratio after compression can be changed. The internal stress distribution state of steel wire makes the tensile strength decrease continuously, the plasticity index increases, and the qualified rate of products will be greatly improved.
在拉拔过程中,弹簧钢丝与拉丝模之间的滑动摩擦可能会导致模孔中钢丝的不均匀变形,并会产生大量热能,增加能耗。这时需要用拉丝粉吹干流平。性能好,同时拉丝时需要经常搅拌,可以防止拉丝粉结焦。
In the drawing process, the sliding friction between the spring steel wire and the drawing die may lead to the uneven deformation of the steel wire in the die hole, produce a lot of heat energy and increase energy consumption. At this time, it is necessary to blow the main stream with wire drawing powder. Good performance. At the same time, it needs to be stirred frequently during wire drawing, which can prevent the coking of wire drawing powder.

在拉丝过程中,要保证模箱和卷筒的冷却水通道通畅,并能保持足够的流量,并保持模箱的干燥和清洁。拉丝机卷筒采用内切缝水冷和外强制风冷。成品卷筒采用内部喷淋水冷却和外部环形间隙强制风冷。使用硬度相对较低的冷却水。水压0.2-0.3MPa,温度不超过30℃。
During wire drawing, ensure that the cooling water channel of the die box and drum is unobstructed, maintain sufficient flow, and keep the die box dry and clean. The drum of wire drawing machine adopts internal slit water cooling and external forced air cooling. The finished drum adopts internal spray water cooling and external annular gap forced air cooling. Use cooling water with relatively low hardness. The water pressure is 0.2-0.3mpa, and the temperature does not exceed 30 ℃.
压缩弹簧的生产过程中,要严格控制“三温一速”,即控制好引线温度、炉温、线温、钢线在炉内的运行速度,从而可以减少钢丝表面的氧化,防止钢丝悬垂。同时可以加强对铅罐的管理,保证铅液表面覆盖严密,钢线可以在铅罐内交叉。
In the production process of compression spring, the "three temperatures and one speed" shall be strictly controlled, that is, the lead temperature, furnace temperature, wire temperature and the running speed of steel wire in the furnace shall be well controlled, so as to reduce the oxidation of steel wire surface and prevent steel wire suspension. At the same time, the management of the lead tank can be strengthened to ensure that the surface of the lead liquid is tightly covered, and the steel wires can cross in the lead tank.
设备原因的话就要根据厂家的实际情况来分析了,如果您对该弹簧的其他方面内容感兴趣的话,就赶紧关注网站www.sdzbthc.com来了解吧。
The reason for the equipment should be analyzed according to the actual situation of the manufacturer. If you are interested in other aspects of the spring, please pay close attention to the website www.sdzbthc.com Come and understand. Com.
