Description

Technical Field

[0001] The utility model relates to the technical field of steel bar cutting, in particular to a steel bar cutting positioner. Background Art

[0002] As an extremely important building material in the construction industry, steel bars are bound to be produced and transported in large quantities. In order to facilitate movement and save transportation space during transportation, steel bars below 10 mm are usually rolled into steel bar rings with a diameter of about 1 meter. However, disc-shaped steel bars cannot be used as materials for construction projects. Therefore, we must use a steel bar straightening and cutting machine to straighten the bent steel bars and cut them into equal-length steel bar segments according to the required length for application in the construction industry.

[0003] A steel bar cutting machine is a tool used to cut steel bars. There are fully automatic steel bar cutting machines and semi-automatic steel bar cutting machines. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, and water cutting machines. Laser cutting machines are the most efficient, with the highest cutting accuracy and generally smaller cutting thickness; plasma cutting machines also have very fast cutting speeds and a certain slope on the cutting surface. Flame cutting machines are used for thicker carbon steel materials.

[0004] At present, when steel bars are cut on construction sites, they are directly placed on the bottom of the cutting machine and fixed by hand. The workers' hands are easily shaken by hand fixation, which is not conducive to the cutting of steel bars. The steel bars are moved by manual transportation, which has low transportation efficiency.
