这是一种供捲取轧制的、特别是热轧厚带材用的机器。它藉助与捲筒串联的弯曲辊组,用逐渐增大弯曲半径的方法来预弯轧出的金属带材,同时不断与增大的带卷直径相适应。弯曲辊组由一对弯曲辊和一个压紧辊组成,后者可在两个弯曲辊之间移动。为了在捲取过程中,自动或强制调整预弯装置,使之与成型的各种弯曲半径相适应,根据发明该机器的机构具有如下特点:捲取心棒就是压紧辊;由于其位置特殊,能与带捲的增大相适应,所以它不仅能一般地上下移动,而且能在弯曲辊之间移动,它与两个弯曲辊之间 This is a machine for roll-to-roll, especially for hot strip. It uses a series of bending rollers in series with a drum to pre-bend the rolled metal strip with a gradually increasing radius of curvature while constantly adapting to the increased roll diameter. Bending rollers consist of a pair of bending rollers and a pressure roller, which can move between two bending rollers. In order to coiling the pre-bending device automatically or forcibly during the coiling process to adapt to the various bending radii of the molding, the mechanism of the machine according to the invention has the following characteristics: the coiling mandrel is the pinch roller; due to its special position, Can be adapted to the increase of the coil, so that it can not only move up and down in general, but also move between the bending rollers, which is in contact with the two bending rollers
