目前国内使用的卷板机大都为非对称式卷板机(因为这种卷板机具有同时弯边的功能),其驱动方式—直都是双辊驱动(如本厂生产的2×1500,2×2000,5×2000,8×2000等)。由于其规格小,所弯板材很薄,且机床各零部件的强度设计都有一定的安全系数,故长期生产使用中并未发生什么大的问题。但随着卷板 At present, most of the domestic use of bending machine for non-symmetrical bending machine (because of this bending machine with the function of bending at the same time), the driving method is straight are two-roll drive (such as the factory production of 2 × 1500, 2 × 2000, 5 × 2000, 8 × 2000, etc.). Because of its small size, the sheet is thin bending, and the strength of the machine parts design have a certain safety factor, so long-term production did not occur in any major problems. But with the coil
