Abstract

A fixed-size saw cutting device for a plastic-steel composite pressure pipe comprises a length measuring mechanism, a saw cutting operating mechanism, a hydraulic power system and an electric control mechanism. The length measuring mechanism comprises counting wheels arranged on the two sides of an inlet pipe opening, a coded disc and an adjusting wheel. The saw cutting operating mechanism comprises a sliding system, a saw cutting system, a clamping system and a returning system. The saw cutting system comprises an executing mechanism and an induction mechanism. The executing mechanism comprises a lifting oil cylinder, a motor, a speed reducer and a low-rotation-speed saw blade, all of which are sequentially connected. The induction mechanism comprises a photoelectric limiting part I and a photoelectric limiting part II which are used for controlling ascending and descending of the low-rotation-speed saw blade. According to the fixed-size saw cutting device, through adjustment of the length measuring mechanism and the saw cutting mechanism, the saw cutting precision of the plastic-steel composite pressure pipe is guaranteed, and the fixed-size saw cutting device is suitable for conducting saw cutting operation on plastic-steel composite pressure pipes with different diameters and wall thicknesses.

Description

technical field [0001] The invention relates to the field of production, in particular to an online fixed-length sawing device for pipes, and more particularly to an improved online fixed-length sawing device for steel-plastic composite pressure pipes. Background technique [0002] In the production process of the steel-plastic composite pressure pipe, it is necessary to cut the pipe according to the fixed length, and the end face after sawing must maintain a certain flatness to ensure better sealing quality and installation quality. The current length measurement mainly relies on the code disc to drive the wheel to be placed above the outer circle of the pipe. When the pipe moves axially, the friction force drives the wheel to rotate to achieve the purpose of counting. Once the pipe vibrates slightly, the counting device will produce errors, and it is difficult to ensure the fixed position. The sawing accuracy of the ruler and the flatness of the sawing end face of the pipe...
