Automatic feeding and discharging device for steel tube cutting

Abstract

The invention discloses an automatic feeding and discharging device for steel tube cutting. The device comprises a feeding frame and a discharging cylinder; a feeding groove is formed in the upper endof the feeding frame, and a squeezing roller is arranged above the feeding groove; the discharging cylinder is connected to the right side of the feeding frame, and a cutting groove is formed in thejunction between the feeding frame and the discharging cylinder; a cutting wheel is arranged above the cutting groove, and the cutting wheel is connected with a cutting motor through an output shaft.By arranging a pushing disk driven by a screw rod and a Maltese crossmovement connected with the screw rod, the pushing disk is driven to push steel tubes for intermittent feeding, and by arranging arotary frame, the discharging cylinder and a drive mechanism connected with the Maltese cross movement, intermittent blanking is achieved, it can be avoided that the steel tubes directly fall, and thesteel tubes are protected; through intermittentfeeding and discharging mechanisms which are composed by two Maltese cross movements, feeding and discharging cooperation is achieved, compared with theartificial feeding and discharging, seamless connection of the feeding and discharging is achieved, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of cutting, in particular to an automatic feeding and discharging device for steel pipe cutting. Background technique [0002] Steel pipes are widely used in various fields. 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] Generally, steel pipes need to be processed on-site at the work site, so large-scale factory processing equipment cannot be used. The traditional steel pipe cutting process requires manual part...

Problems solved by technology

[0003] Generally, steel pipes need to be processed on-site at the work site, so large-scale factory processing equipment cannot be used. The traditional steel pipe cutting process requires manual participation. Pushing and feeding the steel pipes not only consumes a lot of physical strength, but also the operation is not continuous, which reduces production. In addition, at the discharge end, the free fall of the steel pipes after cutting will cause the steel pipes to collide with each other, causing damage to the paint surface and requiring re-stacking; therefore, a simple structure, easy to control and able to overcome manual feeding and discharging is required.
