一方面，它取决于徐州SKF轴承自身的质量，另一方面，它也取决于拉伸条件。

On the one hand, it depends on the quality of Xuzhou SKF bearing itself, on the other hand, it also depends on the stretching conditi***.

（1）还原效应

(1) Reduction effect

在拉拔过程中，拉拔模对钢丝产生压力。当拉模变形时，钢丝在拉模壁上产生反向压力。拉拔时所用的还原率越大，孔壁对钢丝产生的压力越大，钢丝对孔壁产生的反作用力越强。如果这个力大于模具本身的拉拔能力，拉拔模具就会断裂。

During the drawing process, the drawing die produces pressure on the steel wire. When the drawing die is deformed, the steel wire produces reverse pressure on the drawing die wall. The greater the reduction rate used in drawing, the greater the pressure produced by the hole wall on the steel wire, and the stronger the reaction force produced by the steel wire on the hole wall. If this force is greater than the drawing ability of the die itself, the drawing die will break.

（2）润滑油的影响

(2) The influence of lubricating oil

在拉拔过程中，徐州SKF轴承润滑油的质量（作用：减少或避免摩擦磨损）和润滑油供应的充分性影响拉拔模的使用寿命。在拉丝过程中，润滑油具有润滑、冷凝、清洗、防锈等功能。

In the drawing process, the quality of Xuzhou SKF bearing lubricating oil (function: reducing or ***oiding friction and wear) and the sufficiency of lubricating oil supply affect the service life of the drawing die. In the process of wire drawing, lubricating oil has the functi*** of lubrication, condensation, cleaning and rust prevention.

滑丝拉丝机的特点：

The characteristics of slip wire drawing machine:

（1）钢丝绳与卷扬机之间有滑动，易磨损（基本部件失效类型）。主要用于拉拔高*强度铜（化）丝（黄铜丝）。

(1) There is slip between the wire rope and the winch, which is easy to wear (failure type of basic components). Mainly used for drawing high * strength copper (chemical) wire (brass wire).

（2）张力控制灵敏，徐州SKF轴承传动系统简单，电气控制要求不严格。

(2) The tension control is sensitive, the tran***ission system of Xuzhou SKF bearing is simple, and the electrical control requirements are not strict.

（3）加工率高，适用于拉伸塑性好的线材。

(3) High processing rate, suitable for wire with good tensile plasticity.

（4）拉丝速度快。在大多数情况下，轴承疲劳损伤会导致轴承疲劳损伤。一般来说，轴承疲劳损伤造成的损伤只有三分之一来自润滑不顺畅，三分之一来自污染物进入轴承或安装和处理不当。然而，这些类型的损坏都是与工业轴承无关的精*密零件，所以在使用高性能徐州SKF轴承时要小心，即使使用不当，也不能达到预期的性能效果，而且容易造成轴承损坏。

(4) Wire drawing speed is fast. In most cases, bearing fatigue damage will lead to bearing fatigue damage. Generally speaking, only one third of the damage caused by bearing fatigue damage comes from poor lubrication, and one third comes from the incorrect entry of pollutants into the bearing or the improper installation and treatment. However, these types of damages are all precise and compact parts unrelated to industrial bearings, so be careful when using high-performance Xuzhou SKF bearings, even if used improperly, it can not achieve the desired performance results, and easy to cause bearing damage.

（5）易于实现机械化、自动化。轴承具有额定负荷高、噪音低、大大降低维护成本、延长机器运行时间等优点。当识别轴承的真实性时，通过触摸轴承上的钢印来识别轴承的真实性是更快、更准确的。这种***如果用手触摸就没有接触，但用钉子轻轻地触摸徐州SKF轴承就可以感觉到。

(5) It is easy to realize mechanization and automation. Bearing has the advantages of high rated load, low noise, greatly reducing maintenance costs and prolonging machine operation time. When recognizing the authenticity of bearings, it is faster and more accurate to recognize the authenticity of bearings by touching the steel stamps on bearings. This stamp has no contact if it is touched by hand, but it can be felt by touching Xuzhou SKF bearing gently with nails.
