Technical Field

[0001] The present application relates to the field of construction engineering equipment, and in particular to a steel bar cutting machine. Background Art

[0002] Rebar is an important material in construction projects. During construction, it is often necessary to cut longer rebar into segments of the required length. The commonly used equipment for cutting rebar is a rebar cutting machine.

[0003] When using the rebar cutting machine, the rebar is first placed on the workbench, and then the rebar is cut by a grinding wheel or blade. The cut rebar is manually placed into the aggregate frame by the worker, and then the rebar is moved forward to continue cutting.

[0004] With respect to the above-mentioned related technologies, the inventor believes that manually placing the cut steel bar segments from the workbench into the aggregate frame increases the labor intensity of the workers. Summary of the Invention

[0005] In order to reduce the labor intensity of workers when cutting steel bars, the present application provides a steel bar cutting machine.

[0006] This application provides a steel bar cutting machine, which adopts the following technical solution:

[0007] A steel bar cutting machine includes a workbench and a placing component, a cutting component, and a blanking component arranged on the workbench. The placing component is used to place the steel bars to be cut, and the cutting component is used to cut the steel bars. A material collection frame is provided on the workbench, and the material collection frame is located on the side of the workbench facing away from the cutting component. The blanking component includes a blanking lever and a driving member that drives the blanking lever to move toward the material collection frame. Two movable grooves are provided on the surface of the workbench, and the two movable grooves are distributed along the length direction of the steel bars to be cut. The movable groove is arranged in a direction perpendicular to the length of the steel bars to be cut and passes through the side wall of the workbench. Two blanking levers are provided and correspond to the movable grooves one by one. The blanking lever passes through the movable groove from bottom to top and is located on the side of the steel bars to be cut facing away from the material collection frame.

[0008] By adopting the above technical solution, the steel bars to be cut are fixed on the workbench through the placement component, the steel bars are cut by the cutting component, and the unloading lever is pushed by the driving part. The unloading lever pushes the cut steel bars toward the aggregate frame, so that the cut steel bar sections are placed in the aggregate frame, thereby reducing the labor intensity of workers when cutting steel bars.

[0009] Optionally, the driving member includes a main motor, a first lead screw, and a slider. A sliding groove parallel to the moving groove is opened at the bottom of the workbench, and a slider slides in the sliding groove. The first lead screw is rotatably installed on the workbench and is located in the sliding groove. The first lead screw is clamped with the workbench along the length direction of the sliding groove, and the slider is clamped with the slide groove in the rotation direction of the first lead screw. The main motor is set on the workbench and the output shaft is connected to the first lead screw to drive the first lead screw to rotate. The slider is connected to the unloading rod.

[0010] By adopting the above technical solution, the main motor starts to drive the first screw to rotate, thereby driving the slider to move toward the aggregate frame, and then the steel bar segment is pushed toward the aggregate frame through the unloading lever. The structure is simple and the pushing effect is good.

[0011] Optionally, a push piece is provided at the top end of the blanking lever.

[0012] By adopting the above technical solution, the push piece contacts the steel bar segment and pushes the steel bar segment, thereby increasing the contact area and achieving a better pushing effect.

The cross-section of the through groove is dovetail-shaped, and a dovetail block is provided on the side of the push plate facing away from the material collection frame. The dovetail block slides in the through groove, and a tightening bolt is threadedly connected on the material collection rod. The screw of the tightening bolt extends into the through groove and tightens against the dovetail block.

[0014] By adopting the above technical solution, the dovetail block is positioned after the tightening bolt is tightened. When loosened, the dovetail block can move along the through groove to adjust the position of the push piece, thereby better pushing the steel bar segment. The structure is simple and the adjustment is convenient.

[0015] Optionally, the cutting assembly includes a cutting motor, a swing arm and a blade. The swing arm is rotatably arranged on the workbench through a torsion spring and is located on the side of the steel bar to be cut facing away from the aggregate frame. The blade is rotatably installed on the swing arm. The cutting motor is arranged on the swing arm and the output shaft is connected to the blade to drive the blade to rotate.

[0016] By adopting the above technical solution, the cutting motor drives the blade to rotate. When in use, by pressing the swing arm, the blade moves downward and cuts the steel bar. After releasing the swing arm, the torsion spring resets and drives the swing arm to rotate and reset.

[0017] Optionally, a fixed-length component is provided on the workbench, and the fixed-length component includes a fixed-length plate. The fixed-length plate is provided on the workbench, and the fixed-length plate is located on the side of the cutting component facing away from the steel bar to be cut and is used to press against the end of the steel bar to be cut.

[0018] By adopting the above technical solution, the end of the steel bar is pressed against the fixed-length plate, so that the length of the steel bar segment cut each time is equal to the distance from the blade to the fixed-length plate.

[0019] Optionally, the fixed-length component also includes an adjusting block and a positioning bolt. The workbench is provided with a slide rail extending along the length direction of the workbench. The slide rail is located on the side of the cutting component facing away from the steel bars to be cut. The adjusting block is slidably set on the slide rail. The positioning bolt is threadedly connected to the adjusting block and tightened against the slide rail. The fixed-length plate is set on the adjusting block.

[0020] By adopting the above technical solution, the movement of the adjusting block drives the fixed-length plate to move, and then the adjusting block is positioned by the positioning bolts, so as to adjust the length of the steel bar segment cut each time, which can adapt to the situation where steel bar segments of different lengths need to be cut.

[0021] Optionally, the placement assembly includes a left clamping block and a right clamping block, both of which slide horizontally on the workbench in a direction perpendicular to the steel bars to be cut, and a horizontal second screw is rotatably arranged on the workbench, and the second screw is clamped with the workbench in a direction perpendicular to the steel bars to be cut, and the left clamping block and the right clamping block are respectively located on both sides of the steel bars to be cut to form a clamping opening for clamping the steel bars, and the left clamping block and the right clamping block are both threadedly connected to the second screw.

[0022] By adopting the above technical solution, the second screw is rotated, and the left clamping block and the right clamping block can move closer to or farther away from each other, thereby clamping and releasing the steel bars to be cut.
