Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a device for cutting outer layer objects of a pipe. Background Art

[0002] The insulation pipe is divided into an outer sheath, an insulation layer and an inner pipe. After the insulation pipe is produced, it is usually necessary to expose a certain length of the metal inner pipe at the end face to facilitate welding. Therefore, the outer sheath and insulation layer at the end of the insulation pipe need to be cut off to ensure the exposed length of the inner pipe. In this article, the outer sheath and insulation layer are collectively referred to as the outer layer.

[0003] Large diameter insulation pipes have a diameter of more than 1m and a length of up to 10m. Due to their large size, they require large machine tools and fixtures to fix them inside the machine tools. However, the cost of large machine tools is usually high and small and medium-sized enterprises usually cannot afford it. Simple outer layer cutting equipment is more common in small and medium-sized enterprises. This cutting device drives the insulation pipe to rotate by four radial support rollers, and the cutting electric saw at the end moves toward the insulation pipe to achieve outer layer cutting.

[0004] However, due to the large difference in radial dimensions of the insulation pipes (the central axis of the outer layer is not coaxial with the central axis of the inner tube, and the radial support roller drives the insulation pipe to rotate around the axis of its outer layer), it is difficult to unify the saw blade feed amount: when the saw blade rises a large distance, it will cut the metal inner tube, causing the entire tube to be scrapped; when the saw blade rises a small distance, the connection area between the outer layer at the end and the outer layer of the tube body is large, and the remaining area needs to be manually cut along the cut to facilitate the peeling of the outer layer at the end. In order to avoid damage to the inner tube, only a large cutting margin can be left, resulting in a large manual workload and low production efficiency. Utility Model Content
