Description

Technical Field

[0002] During the shipbuilding process, on-site construction workers often need to cut various types of profiles such as round steel pipes, square steel, square tubes, angle irons, bulb flat steel, etc. Generally, small profiles are cut by workers on site using manual cutting motors, but manual cutting motors have relatively large safety risks. Relatively large profiles are cut by workers carrying them off the ship to the workshop using grinding wheel cutting motors, but this is time-consuming and labor-intensive, and wastes labor costs.

[0003] After searching for the steel pipe cutting device with patent publication number CN210451160U, a feeding assembly is welded on one side of the top surface of the workbench, rollers are evenly installed inside the mounting port, studs are passed through both ends of the baffle, a push plate is movably installed on one end of the stud, a supporting inclined plate is welded on the end of the supporting plate away from the baffle, clamping assemblies are installed on the top surfaces of the fixed seat and the movable seat, a clamping tube is placed inside the mounting groove, and a cylinder is installed on the front of the fixed seat and the movable seat by screws. The present invention places the steel pipe on the top surface of the supporting inclined plate, and under the action of gravity, the steel pipe will slide to the top of the supporting plate, adjust the position of the push plate, change the number of steel pipes at the top of the roller, and push the steel pipe at the top of the roller to send it into the cutting position, which is convenient for feeding, saving time and effort, and can feed multiple steel pipes at one time, thereby improving the cutting efficiency. The steel pipe to be cut is clamped by the clamping assembly, and the clamping is stable and not easy to loosen, thereby improving the accuracy of cutting the steel pipe and making cutting more convenient.

[0004] In terms of specific implementation, the above-mentioned technology and the existing technology have the following problems: 1. When the device cuts the steel pipe, a large amount of cutting powder will be generated. The cutting powder lacks a collection device, causing the powder to float in the air. The workers breathe the air containing a large amount of powder for a long time, which will affect their health; 2. The device is too large and not easy to disassemble and transport. The device cannot be easily moved to the construction site. The steel pipe needs to be transported to the factory for cutting, and then the cut steel pipe needs to be transported to the construction site, which is time-consuming and labor-intensive.
