Problems solved by technology

[0003] After the finished steel pipe is produced, it is often cut according to the needs to facilitate transportation and installation. Most of the existing steel pipe cutting is carried out by a manual cutting machine. Manually hold the handle of the cutting machine and press the handle to make the cutting machine cut the steel pipe at the bottom, which is automated. Low degree, high labor intensity

Abstract

The invention discloses a self-feeding continuous cutting device for steel pipes, in particular to a device capable of automatically feeding and cutting steel pipes. The device drives a connecting rod through a crankshaft to drive a beam and a sliding plate to reciprocate and move up and down to drive a telescopic rod. And the driven shaft moves up and down, and the crankshaft that rotates at the same time uses the bevel gear set to drive the driven shaft to rotate, so as to realize the reciprocating up and down rotation of the tool and continuous cutting, and a rack is set under the workbench, and the worm gear is driven by the worm to rotate and then drive The residual gear rotates to realize the intermittent movement function of the rack and the workbench; the top plate is fixed above the side plate, and the drive motor is fixedly installed on one side plate through a flange, and the output end of the drive motor is connected to the crankshaft in rotation, and the crankshaft is fixedly connected to the worm, and the worm The end bearing is rotatably connected to the side wall of the hydraulic cylinder, and a worm gear is meshed under the worm, and the worm gear is connected to the residual gear through a synchronous belt; the toothed part of the residual gear is engaged with the rack, and the rack is fixed under the workbench.

Description

technical field [0001] The invention relates to a mechanical processing and cutting equipment, in particular to a self-feeding continuous cutting device for steel pipes. Background technique [0002] Steel pipes are very common in production and life. Steel pipes are not only used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. It is also an economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save 20-40% of metal, and realize factory-like mechanized construction. The use of steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​the protective layer, saving investment and maintenance costs. [0003] After the finished steel pipe is produced, it is often cut according to the needs to facilitate transportation and installation. Most of the existing steel pipe cutting is c...
