    摘要： A pipe straightener which utilizes V-shaped upper and lower rollers combined with hydraulic cylinders to apply pressure between alternate V-shaped rollers so as the pipe is moved between the rollers the bends and twists are removed therefrom. By adjusting the top and bottom rollers from a right angle with respect to the pipe up to approximately 45* with the upper rollers being adjusted in opposite angular relation to the lower rollers, pipe may be readily straightened. At least some of the upper rollers and some of the lower rollers are power driven, preferably with hydraulic motors, the conduits of which hydraulic motors are connected in series so that all the rollers will be driven at a uniform speed, with certain rollers being idler rollers. The entire device may be mounted on a structural frame, which in turn is mounted on a trailer axle and may be trailed from place to place, which obviates the necessity of bringing the bent or ''''cork screwed'''' pipe to the machine. A V-trough is provided, at one end of the machine, to guide the pipe to and between the rollers and a cone shaped guide is provided at the opposite end for guiding the pipe outward therefrom. The source of hydraulic power is usually furnished by the vehicle towing device, however, a separate and independent hydraulic system, having an outside source of power, may be used, such as a motor or internal combustion engine. Both the upper and lower V-shaped rollers are adjustable to vary the center distances between the rollers to enable the device to be used on pipe of all sizes.

    摘要翻译： 一种管道矫直机，其使用与液压缸结合的V形上下辊来在交替的V形辊之间施加压力，使得管在辊之间移动，弯曲和扭曲被从其移除。 通过将上辊和下辊相对于管直接调节到大约45度，上辊被调节成与下辊成相反的角度关系，管可以容易地矫直。 上辊和一些下辊中的至少一些是动力驱动的，优选地具有液压马达，其液压马达串联连接的导管，使得所有辊将以均匀的速度被驱动，一些滚筒是空转的 滚筒。 整个装置可以安装在结构框架上，结构框架又安装在拖车轴上并且可以从一个地方拖到另一个地方，这样就不需要将弯曲的或“软木螺丝”的管子带到机器上。 在机器的一端设置有V形槽，用于将管道引导到辊子之间并且在辊子之间，并且在相对端处设置锥形引导件，用于将管道向外引导。 液压动力源通常由车辆牵引装置提供，然而，可以使用具有外部动力源的独立且独立的液压系统，例如马达或内燃机。 上下V形辊都可调节，以改变辊之间的中心距离，以使设备能够用于各种尺寸的管道上。
