型材彎曲機是一種高效的加工設備，用于彎曲各種異型鋼材，例如角鋼、槽鋼、工字鋼、扁鋼、方鋼、圓鋼等。彎曲過程中，根據構件形狀的要求，使用型材彎曲機設備和一定的工裝、模具，可以將板材或鋼材彎曲成一定形狀。
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.
型材彎曲機可一次性完成端部預彎和彎曲成型，彎曲形狀多樣。型材可以彎曲成所需的圓形、弧形、螺旋形、橢圓形、U形、凸緣形等。
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.
操作型材彎曲機時，哪些因素會影響回彈？
1. 材料的屈服強度越高，回彈越大。
2. 彎曲半徑r與材料厚度t之比，r/t值越大。
3. 變形面積越大，回彈越大。
4. 材料表面與模具表面之間的摩擦力會影響毛坯各部分的應力狀態。大多數情況下，彎曲變形區的拉應力會增加，回彈會減小。
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.
結論
型材彎曲機結構緊湊、能耗低、效率高、無噪音、安裝使用方便、承載能力強、卷制速度快、產品質量可靠。型材彎曲機是機械制造、石油化工、船舶制造、鋼結構建筑等行業的理想加工設備。
