Description

Technical Field

[0001] This utility model relates to the field of pipe sawing technology, and more specifically, to a pipe length-fixed flying saw device. Background Technology

[0002] In the pipe processing process, pipes often need to be cut. Among them, the flying saw cutting method uses a carriage to drive the sawing mechanism to move at the same speed as the pipe. The following speed of the carriage is dynamically controlled by the pipe moving speed measured by an encoder. After the sawing mechanism is driven by the carriage and moves in sync with the pipe speed, the sawing mechanism cuts the material.

[0003] Existing flying saw equipment has the following shortcomings:

[0004] (i) The trolley is equipped with a sawing mechanism to track the pipe sawing position. When the sawing mechanism achieves synchronous tracking of the pipe, there may be a long distance between it and the equipment feeding point. The part of the pipe between the sawing mechanism and the equipment feeding point lacks support and is prone to sagging under its own weight. This situation is more serious for pipes with small diameters. The sagging of the pipe can lead to vortex tubes, pipe bends, and pipe vibration, which will affect the cutting speed measurement and thus affect the sawing accuracy.

[0005] (ii) Traditional sawing feed methods use hydraulic cylinders or air cylinders to drive the hinge shaft to feed the pipe. The large gaps at the joints result in a short lifespan and the saw blade is prone to shaking, leading to poor cuts. Furthermore, the saw feed distance cannot be adjusted according to the size of the copper pipe, resulting in too much ineffective stroke, which leads to excessive mechanical impact and affects the lifespan.
