卷板机是一种将金属板材卷弯成筒形、弧形或其它形状工件的通用设备,构简单、重量轻、易于制造维修、投资少。此性能被大宽度的使用正在造物、锅炉蒸汽、化工、非金属构造及机器打造等事业上。具有卷制O型、U型、多段R等不同形状板材的功能。根据三点成圆的原理,利用工件相对位置变化和旋转运动使板材产生连续的塑性变形,以获得预定形状的工件。由于结构简单,性能可靠,造价低廉,已经广泛用于锅炉、造船、石油、木工、金属结构及其它机械制造行业。

Plate bending machine is a kind of general equipment which can bend the metal plate roll into cylinder, arc or other parts. It is simple in structure, light in weight, easy to manufacture, maintenance and low in investment. This performance is widely used in the creation, boiler steam, chemical, non-metallic structure and machine building and other undertakings. It has the functions of rolled O, U and multi section R plates with different shapes. According to the principle of three point rounding, the continuous plastic deformation of the plate is obtained by the relative position change and rotation motion of the workpiece, so as to obtain the workpiece with a predetermined shape. Due to its simple structure, reliable performance and low cost, it has been widely used in boilers, shipbuilding, petroleum, carpentry, metal structures and other machinery manufacturing industries.


卷板机按照工作状况分为:冷卷和热卷两种。工作能力是指板材在冷态下,按规定的屈服极限卷制最大板材厚度与宽度时最小卷筒直径的能力。当卷制板厚较大或弯曲半径较小并超过设备工作能力时,在设备允许的前提下可采用热卷的方法。个别不允许冷卷的板材,热卷刚性太差,则采用温卷的方法。

According to the working conditions of rolling machine is divided into two kinds: cold rolled and hot rolled. Work capacity refers to the capacity of the plate to be rolled in the cold state according to the specified yield limit and the maximum diameter and thickness of the maximum plate. When the rolling thickness is larger or smaller than the bending radius and work capability of the equipment, in under the premise of device allows the coil. The individual does not allow the cold rolled sheet, coil rigidity is too poor, adopts the method of the temperature volume.
