Description

Technical Field

[0001] The utility model relates to the technical field of pipeline bending calibration, in particular to a pipeline production bending calibration device. Background Art

[0002] The straightening machine is a detection and straightening device designed for shaft and rod products that undergo bending deformation after heat treatment. The automatic straightening machine is a high-tech product that integrates mechanical, electrical, hydraulic, pneumatic, and computer detection and analysis. It has excellent technical performance, which is mainly reflected in the advantages of high measurement accuracy and strong workpiece adaptability. It can accurately measure the radial runout of pure circular sections, D-shaped sections, and pitch circles of gears or splines of shaft and rod workpieces.

[0003] In actual situations, iron pipes may be slightly bent due to some external forces during the production process. Therefore, a straightening machine is used to straighten the pipes to ensure the yield rate of the pipes. However, the existing straightening machines use hydraulic extrusion for straightening and use a jacking and pushing method to transport materials. In short, only after one pipe is processed can other pipes be processed. This causes the straightening machine to be shut down during the production process, which further leads to low production efficiency of the straightening machine, thereby affecting the processing and production of the pipes.

[0029] Embodiment 3 of a pipe production bending calibration device according to the utility model

[0030] Reference Figure 1 - Figure 4 Specifically, the width of the first fixing groove 1005 and the second fixing groove 1007 matches the outer diameter of the pipe to be straightened, and the distance between the first fixing groove 1005 and the second fixing groove 1007 matches the length of the pipe.

[0031] Specifically, the working principle of the pipe production bending calibration device is as follows: when in use, the second electric telescopic rod 2002 is used to drive the fixed seat 2003 to move, so that the push rod 2004 slides in the through hole 1008 and the second fixed groove 1007, and the push rod 2004 is supported by one end of the pipe, and the other end of the pipe is against the first fixed groove 1005, so that the pipe can be fixed between the first fixed groove 1005 and the second fixed groove 1007, and the first electric telescopic rod 3007 is used to push the moving plate 3004.

The motor 1004 drives the threaded rod 1003 to rotate, so that the slider 3001 moves in the slide groove 1002, thereby driving the moving seat 3002 to move. Since the moving seat 3002 moves in a straight line and the pipe is squeezed by the roller 3005, the pipe will be straightened as the moving seat 3002 moves. At the same time, as the pipe is straightened, the top rod 2004 will be driven by the second electric telescopic rod 2002 to gradually move away from one end of the pipe, leaving a gap between it and one end of the pipe.
