Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, specifically a horizontal double-chuck heavy-duty pipe cutting device. Background Technology

[0002] In modern industrial production, laser tube cutting technology is widely used due to its high efficiency and precision. This patent addresses the technical challenges in the laser cutting of heavy-duty tubes: during the whole-tube cutting process, due to the weight and deformation of the tube, relying solely on traditional single or double chucks for clamping can easily cause significant sagging and vibration in the middle and overhanging ends of the tube, leading to decreased cutting accuracy and poor cross-sectional quality; simultaneously, heavy-duty tubes are prone to collision damage during unloading. Existing solutions using multiple chucks or complex auxiliary supports can partially improve the support effect, but they suffer from high equipment costs, structural redundancy, and cumbersome operation. Therefore, there is an urgent need to develop a horizontal double-chuck heavy-duty tube cutting solution that combines efficient and stable support, precise dynamic correction, and safe unloading capabilities.

The pipe 6 is clamped by the rear chuck assembly 5, the front chuck assembly 7, and the correction assembly 4. In the cutting area and the unloading area, it is supported by the follower assembly 3 and the follower unloading assembly 8, respectively. This support method effectively controls the torsional deformation of the pipe during rotary cutting due to its own weight and material properties, thereby improving cutting accuracy.

[0019] The crossbeam assembly 2 includes crossbeam sliders 21 sleeved on both sides of the bed assembly 1 and a crossbeam frame 20 mounted on the top of the two crossbeam sliders 21.
