φ1020毫米中频弯管机是生产大口径、厚壁管、小曲率半径弯头的专用设备,是迄今为止国内最大的一台中频弯管机。该设备于1978年自制成功,经弯管试验,弯头质量良好。这里简介该设备性能特点、弯曲力矩、及转臂回转点处R_Y力的计算。供有关方面参考。 φ1020 mm IF bending machine is the production of large-caliber, thick-walled tube, small radius of curvature of the elbow special equipment, is by far the largest in the country a IF pipe bender. The device was made in 1978, after the elbow test, elbow good quality. Here is a brief description of the equipment’s performance characteristics, bending moment, and calculation of the R_Y force at the turning point of the boom. For reference.
