楔橫軋技術(shù)是一種低耗的先進(jìn)生產(chǎn)工藝在連桿生產(chǎn)線上采用楔橫軋制坯熱模鍛壓力機(jī)成形工藝生產(chǎn)連桿鍛件具有其它鍛造工藝無法相比的獨(dú)特優(yōu)勢與輥鍛工藝相比材料利用率提高10%以上勞動(dòng)生產(chǎn)率提高30 50%

Cross wedge rolling technology is an advanced production process with high precision, high efficiency, high efficiency and low cumption. On the connecting rod production line, the forming process of the die forging press of the wedge rolling blank is adopted to produce the connecting rod forgings with the unique advantages of other forging processes. Compared with the roll forging process, the utilization ratio of materials is raised by more than 10% of the labor productivity by 3050%.

楔橫軋工藝的基本原理是，將加熱后的棒材送入兩個(gè)同向旋轉(zhuǎn)的帶有楔性凸起的模具中間，棒材在模具的帶動(dòng)下，作與模具反向的回轉(zhuǎn)運(yùn)動(dòng)，同時(shí)材料發(fā)生徑向壓縮變形和軸向延伸變形，從而成形階梯軸類零件。

The basic principle of the cross wedge rolling process is to send the heated bar into the middle of two same revolving moulds with wedge-shaped protrusi. The rod is driven by the mold to make the reverse rotation movement with the mold. At the same time, the material has radial compression deformation and axial extension deformation, thus forming a staircase type part.

軋制時(shí)毛坯的位置固定，因此不需設(shè)置側(cè)向支撐毛坯的導(dǎo)向尺?？傊?，它適用于軋制復(fù)雜外形結(jié)構(gòu)，精度要求高，零件品種變換很多的情況。但其行程大小受到限制，所以，變形程度也受到影響，同時(shí)，板式軋機(jī)有空行程，故影響到生產(chǎn)率和變形程度都不能很大。

The of the blank is fixed during rolling, so there is no need to set the guide bar of the side supporting blank. In short, it is suitable for rolling complex shape structure with high accuracy and many varieties of parts. But the stroke size is limited, so the degree of deformation is also affected. At the same time, the plate mill has an empty travel, so the productivity and deformation can not be very large.

還有三輥軋機(jī)，軋機(jī)專業(yè)廠家介紹，這種軋機(jī)由于本身的優(yōu)勢并不突出，所以使用的比較少。那么，四輥軋機(jī)具有怎樣的特點(diǎn)恩？這種機(jī)架兼有開口式機(jī)架和閉口式機(jī)架的優(yōu)點(diǎn)，裝卸、換輥方便，制造容易，并有較高的剛度，故一般大中型的型鋼軋機(jī)都采用這種形式的機(jī)架。這種類型的軋機(jī)的工作輥直徑較小，傳遞軋制力矩，軋延壓力由直徑較大的支承輥承受。其的優(yōu)點(diǎn)在于相對剛度高、壓下量大、軋延力小，比較適合軋制較薄的板材。

There are three-high mill, mill professional manufacturers , this kind of mill because of its advantages are not prominent, so the use of less. So, what are the characteristics of the four high rolling mill?Generallyspeaking,rollingmillsusuallyrefertoonlythemainequipments。 The working roll diameter of this type of mill is smaller, the rolling torque is transmitted, and the rolling pressure is borne by the backup roll with larger diameter. Its advantages are high relative stiffness, large reduction and small rolling force, so it is suitable for rolling thin sheets.
