Packaging steel strip terry, will be the order of the bending

Packaging steel strip terry shed, the bending sequence can be divided into four categories: ( 1) Bending mode at the same time, suitable for single or continuous molding process steel, Z section steel, corrugated plate opening symmetric and asymmetric small channel. ( 2) Order bending methods, including from the blank on both sides to the central order for molding and order from the billet center to both sides, is suitable for single or continuous process held steel, semi-closed sections and corrugated plate. ( 3) Joint bending mode, is the combination of the above two ways, suitable for production of 2 - this way Five asymmetric bending parts of the steel, closed sections and semi-closed steel, but not suitable for production of corrugated board. ( 4) Bending plastic way, this way with large bending radius bending at the first bend Angle, then the plastic, the method is suitable for the high quality the corrugated plate bending. The ability of the distribution of the bending Angle by molding machine, molding time, frame spacing, the total deformation factors such as the decision. Generally, at the beginning of the forming smaller bending Angle to avoid forced bite; In the middle of the molding should be avoided due to the uneven distribution of bend Angle deformation of the strip local anomalies and profile of the surface scratch; In the late forming using smaller deformation in order to prevent the rebound, ensure the accuracy of the product size.
