Bending mold for various vehicle frame main beams

The invention discloses a bending mold for various vehicle frame main beams, and aims at providing a vehicle frame main beam bending mold with high universality and wide variation range. The vehicle frame main beam has the advantages that there exists no bending defect after being bent, original mechanical strength is not consumed, and the position degree is high. The mold is mainly composed of anupper mold seat, a protruded mold, a concave mold, a lower mold seat, an unloading device, a guiding device and the like. The bending mold is installed on a press machine to perform vehicle frame main beam bending. The production and manufacturing cost of the vehicle frame main beam is reduced, and the production efficiency is improved. 本发明公开了种用于各类车架主梁的弯曲模具,旨在提供种通用性强、变化范围广的车架主梁弯曲模具。车架主梁弯曲后折弯处没有折弯缺陷，不损耗原机械强度，并且位置度高。该模具主要由上模座，凸模，凹模，下模座，卸料装置与导向装置等部件组成。安装在压力机上执行车架主梁弯曲。本发明降低了车架主梁生产制造成本，提高了生产效率。
