Abstract
The utility model discloses a built-in three roller guide device, which solves the problem that a well rolled steel pipe can not be directly routed up after being guided through a conventional built-in three roller guide device. According to the structure of the built-in three roller guide device in machine, two hydraulic cylinders are arranged in a frame, wherein one hydraulic cylinder is used for fully opening guide rollers and the other hydraulic cylinder is used for driving a lever. Therefore, the opening degrees of the three guide rollers can be adjusted. Four swing arms arranged in the frame are connected with the frame through three hinge shafts and can be rotated. The four swing arms are mutually connected into one piece through connecting rods. When one swing arm is driven by the hydraulic cylinders to move, the other swing arms are drive to move simultaneously so as to control the adjustment of the opening degrees of the three guide rollers. The L-shaped swing arm and the in-line-shaped swing arm arranged on the same hinge shaft are connected with each other through a hydraulic cylinder or a cylinder. When the hydraulic cylinder or the cylinder is operated, the guide rollers arranged above the hydraulic cylinder or the cylinder are fully opened. Due to the adoption of the built-in three roller guide device, guide rollers can be fully opened and the production efficiency is improved.
