Description

Technical Field

[0001] The present application relates to the technical field of cutting machines, and in particular to a construction steel bar cutting device. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is round, sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. Rebar for reinforced concrete refers to straight bars or coils used for reinforced concrete reinforcement. Its appearance is divided into plain round steel bars and deformed steel bars. It is delivered in straight bars and coils.

[0003] In the patent number CN219130626U, the up and down movement of the pad is combined by a linkage mechanism. When the steel bar is placed on the pad, the pad will move down due to the deadweight of the steel bar, so that the operating frame can be opened at a larger angle for easy operation. At this time, the steel bar will contact the support rollers on both sides for easy pushing. When the operating frame is pressed for cutting, the pad will move up due to the transmission effect of the linkage mechanism, so that the two sides of the steel bar are separated from the support rollers to ensure stability during cutting. This device ensures stability during cutting while ensuring convenient pushing of the steel bar.

[0004] Although the above-mentioned prior art can ensure the stability during cutting, debris and dust will be generated during cutting. If the smoke and dust generated during cutting is not handled in time, it will be inhaled by the human body, causing respiratory irritation and causing great harm to the human body. It will also cause pollution to the surrounding environment and air. Therefore, a construction steel bar cutting device is provided. Utility Model Content
