型材弯曲机是一种高效的加工设备，用于弯曲各种异型钢材，例如角钢、槽钢、工字钢、扁钢、方钢、圆钢等。弯曲过程中，根据构件形状的要求，使用型材弯曲机设备和一定的工装、模具，可以将板材或钢材弯曲成一定形状。
型材弯曲机可一次性完成端部预弯和弯曲成型，弯曲形状多样。型材可以弯曲成所需的圆形、弧形、螺旋形、椭圆形、U形、凸缘形等。
Profile bending machine is a kind of efficient processing equipment used for bending various special-shaped steels such as angle steel, channel steel, I-beam, flat steel, square steel, round steel, etc. During bending, according to the requirements of the component shape, the profile bending machine equipment and certain tools and molds can be used to bend the plate or steel into a certain shape.
The
profile bending machine can complete the end pre-bending and bending forming in one loading, and the bending shape is diversified. The profile can be bent into the required circular, arc, spiral, elliptical, U-shaped, flange shape, etc.
操作型材弯曲机时，哪些因素会影响回弹？
1. 材料的屈服强度越高，回弹越大。
2. 弯曲半径r与材料厚度t之比，r/t值越大。
3. 变形面积越大，回弹越大。
4. 材料表面与模具表面之间的摩擦力会影响毛坯各部分的应力状态。大多数情况下，弯曲变形区的拉应力会增加，回弹会减小。
What factors affect rebound when operating the profile bending machine
1. The higher the yield strength of the material, the greater the rebound.
2. The ratio of the bending radius r to the material thickness t, the larger the value of r/t.
3. The larger the deformation area, the greater the rebound.
4. The friction between the material surface and the mold surface affects the stress state of each part of the blank. In most cases, the tensile stress in the bending deformation zone will be increased, and the rebound will be reduced.
