Description

Technical Field

[0002] The rebar cutting machine is a tool used to shear rebar. It is one of the indispensable equipment for rebar processing. It is mainly used for cutting rebar to a fixed length in house construction, bridges, tunnels, power stations, large-scale water conservancy projects and other projects. It is usually placed according to the use environment, so that the rebar cutting machine can cut the rebar according to the use requirements.

[0003] In view of the current steel bar cutting and processing technology field, corresponding solutions have been formulated for the following existing problems:

[0004] When the rebar cutting machine is in use, the operator usually cuts the longer rebars. Due to the characteristics of the longer rebars, the tail of the rebar will swing when cutting, and the rebar body will jump and swing on the support frame. When the swing amplitude is large, it is easy to cause injury to the operator, which poses certain safety hazards. In order to avoid accidental injuries, two operators are usually responsible for the cutting of the rebar. The operators need to assist each other in cutting the rebar, and they also need to straighten the overall posture of the rebar when cutting, and align the rebar head with the cutting port. The required labor is large, which reduces the cutting efficiency of the rebar. Utility Model Content

[0038] The working principle of the utility model of a hydraulic steel bar cutting machine for construction:

[0039] When the hydraulic steel bar cutting machine is used in construction, the operator lays the steel bars to be cut on the auxiliary cutting frame, and places the steel bars in the auxiliary feeding mechanism and the limiting structure installed on the surface of the auxiliary cutting frame;

[0040] Then, the operator places the steel bars in the auxiliary feeder structure through symmetrically placed support blocks according to the steel bar placement requirements, and the lower surface of the steel bars is supported by pads. After the operator has completed the stacking of the steel bars, the lateral fixed structure is adjusted. The operator pushes the fixed inclined plates in the lateral fixed structure to both sides of the steel bars, and limits the sides of the steel bars laterally through the symmetrically distributed fixed inclined plates. Then, the operator locks the positioning bolts and fixes the moving guide rod with the fixed inclined plates to keep the working position of the fixed inclined plates stable.

[0041] Then the operator installs the limit rope on the limit seat, and the upper surface of the steel bar can be limited by the limit rope. The two ends of the limit rope are clamped into the L-shaped installation groove of the limit seat, and the end of the limit rope is clamped into the limit hole. The remaining activity of the limit rope after installation can be adjusted by the installation position of the limit rope buckles installed at both ends of the limit rope, and the swing amount of the tail of the steel bar can be adjusted;

[0042] The working positions of the auxiliary feeding mechanism and the limiting structure can be freely adjusted according to the working requirements. The limiting structure is fixed by fixing bolts on both sides to prevent the limiting structure from jumping significantly during the steel bar working.

[0043] The distance between the lateral fixed structure and the support block can be adjusted according to the size of the steel bars to facilitate the feeding of the steel bars. The size of the pad can be replaced according to demand to assist in the feeding of the steel bars.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
