產(chǎn)品詳情
一方面,它取決于徐州SKF軸承自身的質(zhì)量,另一方面,它也取決于拉伸條件。
On the one hand, it depends on the quality of Xuzhou SKF bearing itself, on the other hand, it also depends on the stretching conditions.
(1)還原效應(yīng)
(1) Reduction effect
在拉拔過(guò)程中,拉拔模對(duì)鋼絲產(chǎn)生壓力。當(dāng)拉模變形時(shí),鋼絲在拉模壁上產(chǎn)生反向壓力。拉拔時(shí)所用的還原率越大,孔壁對(duì)鋼絲產(chǎn)生的壓力越大,鋼絲對(duì)孔壁產(chǎn)生的反作用力越強(qiáng)。如果這個(gè)力大于模具本身的拉拔能力,拉拔模具就會(huì)斷裂。
During the drawing process, the drawing die produces pressure on the steel wire. When the drawing die is debed, 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 reb 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)潤(rùn)滑油的影響
(2) The influence of lubricating oil
在拉拔過(guò)程中,徐州SKF軸承潤(rùn)滑油的質(zhì)量(作用:減少或避免摩擦磨損)和潤(rùn)滑油供應(yīng)的充分性影響拉拔模的使用壽命。在拉絲過(guò)程中,潤(rùn)滑油具有潤(rùn)滑、冷凝、清洗、防銹等功能。
In the drawing process, the quality of Xuzhou SKF bearing lubricating oil (function: reducing or avoiding 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 functions of lubrication, condensation, cleaning and rust prevention.
滑絲拉絲機(jī)的特點(diǎn):
The characteristics of slip wire drawing machine:
(1)鋼絲繩與卷?yè)P(yáng)機(jī)之間有滑動(dòng),易磨損(基本部件失效類型)。主要用于拉拔高*強(qiáng)度銅(化)絲(黃銅絲)。
(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)張力控制靈敏,徐州SKF軸承傳動(dòng)系統(tǒng)簡(jiǎn)單,電氣控制要求不嚴(yán)格。
(2) The tension control is sensitive, the transmission system of Xuzhou SKF bearing is simple, and the electrical control requirements are not strict.
(3)加工率高,適用于拉伸塑性好的線材。
(3) High processing rate, suitable for wire with good tensile plasticity.
(4)拉絲速度快。在大多數(shù)情況下,軸承疲勞損傷會(huì)導(dǎo)致軸承疲勞損傷。一般來(lái)說(shuō),軸承疲勞損傷造成的損傷只有三分之一來(lái)自潤(rùn)滑不順暢,三分之一來(lái)自污染物進(jìn)入軸承或安裝和處理不當(dāng)。然而,這些類型的損壞都是與工業(yè)軸承無(wú)關(guān)的精*密零件,所以在使用高性能徐州SKF軸承時(shí)要小心,即使使用不當(dāng),也不能達(dá)到預(yù)期的性能效果,而且容易造成軸承損壞。
(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-perbance Xuzhou SKF bearings, even if used improperly, it can not achieve the desired perbance results, and easy to cause bearing damage.
(5)易于實(shí)現(xiàn)機(jī)械化、自動(dòng)化。軸承具有額定負(fù)荷高、噪音低、大大降低維護(hù)成本、延長(zhǎng)機(jī)器運(yùn)行時(shí)間等優(yōu)點(diǎn)。當(dāng)識(shí)別軸承的真實(shí)性時(shí),通過(guò)觸摸軸承上的鋼印來(lái)識(shí)別軸承的真實(shí)性是更快、更準(zhǔn)確的。這種郵票如果用手觸摸就沒(méi)有接觸,但用釘子輕輕地觸摸徐州SKF軸承就可以感覺(jué)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.
