卷板機是一種將金(jin)屬(shu)(shu)板(ban)材(cai)卷彎成(cheng)筒形(xing)(xing)、弧形(xing)(xing)或(huo)其(qi)它形(xing)(xing)狀(zhuang)工(gong)件(jian)(jian)的(de)通用設備，構(gou)簡單(dan)(dan)、重量輕(qing)、易于制(zhi)造(zao)維修、投資少。此性(xing)能被大寬度的(de)使(shi)用正在造(zao)物、鍋(guo)(guo)爐(lu)蒸汽、化(hua)工(gong)、非金(jin)屬(shu)(shu)構(gou)造(zao)及機器打造(zao)等事業上(shang)。具有(you)卷制(zhi)O型、U型、多(duo)段R等不(bu)同形(xing)(xing)狀(zhuang)板(ban)材(cai)的(de)功能。根據三點成(cheng)圓的(de)原(yuan)理，利用工(gong)件(jian)(jian)相對位(wei)置變(bian)化(hua)和旋轉(zhuan)運動(dong)使(shi)板(ban)材(cai)產生(sheng)連續的(de)塑性(xing)變(bian)形(xing)(xing)，以獲得預定(ding)形(xing)(xing)狀(zhuang)的(de)工(gong)件(jian)(jian)。由于結(jie)構(gou)簡單(dan)(dan)，性(xing)能可靠，造(zao)價(jia)低廉(lian)，已經廣泛(fan)用于鍋(guo)(guo)爐(lu)、造(zao)船、石油(you)、木工(gong)、金(jin)屬(shu)(shu)結(jie)構(gou)及其(qi)它機械制(zhi)造(zao)行業。

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(juan)(juan)(juan)板機(ji)按照(zhao)工作(zuo)狀況分為：冷(leng)卷(juan)(juan)(juan)和熱卷(juan)(juan)(juan)兩種。工作(zuo)能力是指板材在冷(leng)態下(xia)，按規定的(de)屈(qu)服極限卷(juan)(juan)(juan)制(zhi)(zhi)最(zui)大板材厚(hou)度與寬度時最(zui)小(xiao)卷(juan)(juan)(juan)筒(tong)直徑(jing)的(de)能力。當卷(juan)(juan)(juan)制(zhi)(zhi)板厚(hou)較大或彎曲半徑(jing)較小(xiao)并超過(guo)設備工作(zuo)能力時，在設備允許的(de)前(qian)提下(xia)可采(cai)用(yong)熱卷(juan)(juan)(juan)的(de)方法(fa)。個別不允許冷(leng)卷(juan)(juan)(juan)的(de)板材，熱卷(juan)(juan)(juan)剛(gang)性太差，則采(cai)用(yong)溫卷(juan)(juan)(juan)的(de)方法(fa)。

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.
