摘要： A dual-directional pipe-bending machine bends a pipe in either direction and has a base, a transporting device and a pipe-bending assembly. The base has a bracket. The transporting device is mounted slidably on the bracket. The pipe is mounted on the transporting device. The pipe-bending assembly is mounted on the base and has a transversely moving bracket, a vertically moving bracket, a location-changing assembly, a rotating transmission device, a rotating bracket and two pipe-bending devices. The transversely and vertically moving brackets are mounted on the base. The location-changing assembly moves the transversely moving bracket and the vertically moving bracket. The rotating bracket connects to the vertically moving bracket. The rotating transmission device rotates the rotating bracket. The two pipe-bending devices are mounted on the rotating bracket.

摘要： A pipe bending machine accurately controlling bent angle of material pipes includes a base, a material feeding device fixed on the base, an arm-turning shaft fixed in front of the base, a bending mold fixed on the arm-turning shaft, a turning arm rotated by a transmitting device. The turning arm has a clamp mold fixed thereon for clamping a material pipe with help of the bending mold. The transmitting device includes a threaded rod rotated by a motor, a threaded nut screwing with the threaded rod and connected with a pull block, and an interactive device positioned between the pull block and arm-turning shaft. Rotation force of the motor is converted into straight pushing force by means of the threaded rod and the threaded nut. At this time, counter pressure of the ball threaded rod can easily reach zero, so even if a speed reducer of high counter-pressure is provided, the threaded rod can reduce largely the counter-pressure of the speed reducer because of the counter-pressure produced before the threaded rod changes speed. Then the pipe bending machine can accurately bends pipes with high speed.
摘要翻译：精密控制材料管弯曲角度的弯管机包括基座，固定在基座上的送料装置，固定在基座前面的手臂转动轴，固定在手臂转动轴上的弯曲模具，转动臂由发送装置旋转。转动臂具有固定在其上的夹具，用于在弯曲模具的帮助下夹紧材料管。传动装置包括由马达旋转的螺纹杆，螺纹螺母与螺杆螺纹连接并与拉块连接，以及定位在拉块和手臂转动轴之间的交互式装置。马达的旋转力通过螺杆和螺母转换为直推力。此时，球杆螺杆的反压力可以容易地达到零，因此即使提供了高反压减速器，由于反压力，螺杆也可大大降低减速器的反压力生产之前螺杆变速。然后弯管机可以精确地弯曲高速管道。

摘要： A tube bender includes a worktable, a rail on the worktable, a tube-pushing device and a tube-bending device. The tube-pushing device is positioned on the worktable, having a moving base and a clamper at one side of the moving device. The clamper clamps a tube being bent, and a push driver moves the moving base together with the tube work to a preset location. The tube-bending device consists of a base unit, a guide unit and a driving unit, and when the tube work is moved to the tube-bending device, it is bent by the tube-bending device, with a guide roller and a main roller sandwiching the tube for preventing the bent section of the finished tube from disfiguring.
