目前在我国起重行业流行的“折线卷筒”一词,是指从国外引进的一种适合钢丝绳多层卷绕的绳槽形式。由于这种绳槽在卷筒周向的大部分区段上保持与法兰端面平行,只在很小的区段上与法兰端面相交,因此绳槽必然出现拐折现象,故而得名“折线卷筒”。折线卷筒整体加工成形可以在车床上,也可以在铣床上实现。车床上加工利用靠模、挂轮装置或数控等多种方法,加工大直径的卷筒要有相应的重型车床。也可以用数控铣床以铣代车加工成形。本文主要介绍折线卷筒的在CK61200X6/8数控重型车床上加工成形的工艺,是我公司首创的折线卷筒加工工艺。
Currently in our lifting industry popular “Polyline”, refers to the introduction from abroad for a multi-layer rope rope winding rope form. Because of this rope groove in most of the circumferential section of the drum remain in parallel with the end face of the flange, only in a small section of the flange face intersect, so the rope groove is bound to appear inflection, so named “Polyline”. Polyester roll overall processing can be formed on the lathe, milling machine can also be achieved. Lathe processing rely on the model, hanging gear or numerical control and other methods, the processing of large diameter drums have a corresponding heavy lathe. Can also be used to milling milling CNC milling machine forming. This article mainly introduces the process of forming and reeling on the CK61200X6 / 8 CNC heavy duty lathe, which is the first of our company’s folding reel processing technology.
