Continuous adjustable small-diameter steel pipe cutting device

Abstract

The invention discloses a continuous adjustable small-diameter steel pipe cutting device, and belongs to the technical field of steel pipe cutting equipment. The continuous adjustable small-diameter steel pipe cutting device includes a fixed base, supporting frames are mounted on both sides of the upper end of the fixed base, a roof is mounted at the top ends of the supporting frames, a motor seatis mounted in the middle of the lower end of the fixed base, a motor is mounted at the lower end of the motor seat, the output shaft of the motor is connected with a driving belt wheel, and the driving belt wheel is connected with driven belt wheels through two belts wheels; and the driven belt wheels are coaxially connected with transmission rollers and worm wheels, the left end of the worm wheel on the left side is meshed with a left worm, the right end of the worm wheel on the right side is meshed with a right worm, driving gears are mounted at the top ends of the left and right worms respectively, the upper ends of the driving gears are meshed with driven gears, a rotating shaft is mounted between the driven gears, and a crank is arranged in the middle of the rotating shaft. The continuous adjustable small-diameter steel pipe cutting device realizes the continuous transmission of the steel pipe, meanwhile, achieves the up and down moving of a moving cutting knife through the cooperation between the crank and a rotating sleeve, ensures the automatic cutting of the steel pipe and reduces the labor strength of the workers.

Description

technical field [0001] The invention relates to the technical field of steel pipe cutting equipment, in particular to a continuous adjustable small-diameter steel pipe cutting device. Background technique [0002] Steel pipe refers to a steel material with a hollow section whose length is much greater than the diameter or circumference. According to the cross-sectional shape, it is divided into circular, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; Steel pipes for thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, they are divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) Two kinds, welded steel pipe is divided into st...

Problems solved by technology

[0004] At present, the existing steel pipe cutting devices on the market are fixed by manual hand-held cutting when cutting steel pipes, which will cause deviations in cutting due to shaking of the arm when manual hand-held cutting. Moreover, manual hand-held cutting will have certain dangers. Chinese patent (notification number: CN208214454U) discloses a steel pipe cutting device applied to building construction, including a base, a sliding wheel, a spacer block, a first screw, a first Motor, first moving rod, first arc clamp, second lead screw, second motor, second moving rod, second arc clamp, vertical rod, cross bar, runner, conveyor belt, first motor, The first belt, the fixed block, the mounting arm, the rotating shaft, the fixed seat, the platform, the first hinged seat, the second hinged seat, the air pressure rod, the cutting piece, the second motor and the second belt, the device enables the steel pipe to be automatically fixed after being fixed. Cutting, although the cutting efficiency can be increased to a certain extent, but continuous cutting cannot be achieved. After each cutting, it needs to be sent to the steel pipe again, which seriously affects the cutting efficiency. At the same time, the cutting length cannot be adjusted in real time. Therefore, it needs to be improved.
