    • The present invention relates to a device for bending an impact beam (1) for a vehicle bumper so as to have curvature and includes: a main body part (10) that includes a support (11) so as to support the beam (1) and at least bending die (15) with the set curvature on the support (11) to be replaced; a clamping part (20) that is provided in the upper center of the main body part (10) and includes a fixing die (25) lifted by a cylinder (21) so as to fix the beam (1) mounted on the bending die (15); a bending part that is provided on both sides of the clamping part (20) to be able to rotate and includes a roller (31) pressurizing and bending the beam (1) fixed to the bending die (15) to have the set curvature; and a detection means that detects the location according to the posture of the bending part (30) and generates a signal according to the detected location. The present invention can automatically perform bending according to the set value by relatively simple operation, so that the productivity can be improved, and satisfies the required specification for the bumper by the compatibility that is capable of handling the curvature caused by various designs and the preciseness that minimizes surface crack and wrinkle, thereby ensuring the excellent quality and stability.
    • 本发明涉及一种用于弯曲用于车辆保险杠的冲击梁(1)以具有曲率的装置,包括:主体部分(10),包括支撑梁(11)以支撑梁(1) 并且至少在所述支撑件(11)上具有设定曲率的弯曲模具(15)被更换; 夹持部件(20),其设置在主体部(10)的上部中心,并具有由气缸(21)提升的固定模具(25),以固定安装在弯曲模具上的梁(1) (15); 弯曲部,其设置在所述夹持部(20)的两侧以能够旋转,并且包括对固定到所述弯曲模(15)的所述梁(1)进行加压和弯曲以具有设定的曲率的辊(31) 以及检测装置,其根据弯曲部(30)的姿势来检测位置,并根据检测到的位置产生信号。 本发明可以通过相对简单的操作自动执行根据设定值的弯曲,从而可以提高生产率,并且通过能够处理由各种设计引起的曲率的兼容性和精度来满足缓冲器的所需规格 使表面裂纹和皱纹最小化,从而确保优异的品质和稳定性。
