Description

Technical Field

[0001] The invention relates to the technical field of steel bar equidistant cutting, in particular to a steel bar equidistant cutting device for construction engineering. Background Art

[0002] With the continuous development of the construction engineering field, the demand for steel bars, as important load-bearing components in building structures, is increasing day by day. During the construction process, steel bar cutting is an important link in steel bar processing. Traditional steel bar cutting equipment is mostly operated manually or semi-automatically, which is not only inefficient but also has low cutting accuracy. Especially in scenarios where multiple equal-distance cutting is required, traditional equipment cannot automatically complete accurate equal-distance cutting and often needs to rely on manual measurement and manual adjustment, which increases the difficulty of operation and the possibility of errors.

[0003] The existing Chinese patent with publication number CN114160715B includes: a workbench; a support frame fixedly connected to the middle of one side of the top of the workbench; a shell installed on the other side of the top of the workbench; a driving mechanism installed between the inner side of the shell and the other side of the top of the workbench, and the driving mechanism is located on the inner side of the shell; a sliding frame connected to the driving mechanism; a motor installed on the inner side of the sliding frame; a cutting wheel connected to the output shaft of the motor; a clamping mechanism arranged in the middle of the top of the workbench, and the clamping mechanism is located on one side of the inner side of the shell.

[0004] When the above device is in use, the cylinder piston rod is extended, thereby driving the sliding frame and the pulley to move downward, so that the pulley contacts the connecting rod, and then drives the connecting rod, the clamping rod and the third guide rod to move inward, so that the clamping rod clamps the steel bar, thereby increasing the stability of the steel bar when cutting. However, in actual use, personnel are required to manually move the steel bar frequently for cutting operations, which is time-consuming and labor-intensive, and personnel frequently contact the equipment, which poses certain safety hazards and can easily lead to accidents. Therefore, it is difficult to automatically move the steel bar equidistantly.

[0010] Preferably, the adjustment mechanism includes an L-shaped frame fixedly connected to the track plate at symmetrical positions on both sides away from one end of the L-shaped plate, and the two L-shaped frames are penetrated and rotatably connected to the opposite surfaces near the end portions with a rotating shaft, and the rotating shaft is rotatably connected to the outer contour of the symmetrical position near the two ends to pull the cutting wheel to perform lifting and reciprocating movement, and the two L-shaped rods are provided with movable grooves for supporting the columnar rods at one end close to the L-shaped plate, and the two columnar rods are respectively penetrated to the inner wall of the movable groove on the adjacent side and are movably connected.

[0011] Preferably, the two fixed blocks are fixedly connected with a connecting seat on the opposite surfaces close to one side of the L-shaped frame, and the connecting seat is rotatably connected with a second pull rod for pulling the L-shaped rod to swing back and forth through a pin shaft. The opposite surfaces of the two L-shaped rods away from one end of the columnar rod are penetrated and fixedly connected with a fixed shaft, and the end of the second pull rod away from the connecting seat is penetrated by the fixed shaft and rotatably connected.

[0012] Preferably, the L-shaped plates on both sides are penetrated near the bottom ends and movably connected with moving rods for horizontal reciprocating movement, and the opposite ends of the two moving rods are fixedly connected with arc-shaped clamping plates for clamping and limiting the steel bars.

[0014] Preferably, the auxiliary mechanism comprises two movable blocks whose opposite sides are fixedly connected with inclined plates for pushing the movable rods to move toward each other, and the opposite ends of the two movable rods are fixedly connected with protrusions for moving in coordination with the inclined surfaces of the inclined plates.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. A crank is arranged on the L-shaped plate, and the crank is driven to rotate by a motor. The motor can drive the crank to rotate on the L-shaped plate, and the connecting shaft supports the first pull rod and the locking block, so that the first pull rod can pull the moving block to move horizontally back and forth along the inner wall of the track plate under the action of the connecting shaft. With the moving block being located in an initial position away from one end of the L-shaped plate, when the first pull rod pulls the moving block to move horizontally toward the end close to the L-shaped plate, the locking block rotates in the C direction under the pull of the first pull rod, so that the bottom end of the locking block rotates and conflicts with the steel bar on the inner wall of the limiting groove, and the locking block can lock the steel bar on the inner wall of the limiting groove, thereby moving The block can pull the steel bar to move synchronously. As the moving block moves to the extreme position close to one end of the L-shaped plate, when the first pull rod pushes the moving block to move horizontally toward the end away from the L-shaped plate, the locking block rotates in the opposite direction of C under the push of the first pull rod, and the bottom end of the locking block rotates and disengages from the steel bar on the inner wall of the limiting groove. The locking block then releases the locking state of the steel bar on the inner wall of the limiting groove. At this time, the steel bar on the inner wall of the limiting groove remains stationary, and then the moving block can move along the outer contour of the steel bar to the initial position away from one end of the L-shaped plate. As the moving block performs horizontal reciprocating movement, it further realizes the equidistant movement of the steel bar and improves the cutting efficiency.

[0016] Second, as the moving block moves the steel bar toward one end of the L-shaped plate, the second pull rod can pull the end of the L-shaped rod close to the L-shaped frame to rotate in the downward direction under the action of the moving block, and the end of the L-shaped rod close to the L-shaped plate rotates in the upward direction, so that the columnar rod can pull the moving block to move along the inner wall of the rectangular slide groove in the upward vertical direction under the action of the movable groove, and the fixed seat drives the cutting wheel to move and disengage from the bottom steel bar under the action of the columnar rod, so that the moving block can move the steel bar equidistantly, avoiding the cutting wheel from hindering the movement of the steel bar; As the moving block resets toward the end away from the L-shaped plate, the second pull rod can push the L-shaped rod close to the L-shaped frame end to reset and rotate in the upward direction under the action of the moving block, and the L-shaped rod close to the L-shaped plate end rotates in the downward direction, so that the columnar rod pulls the movable block along the inner wall of the rectangular slide groove in the downward vertical direction under the action of the movable groove, so that the fixed seat drives the cutting wheel to move downward under the action of the columnar rod to cut the bottom steel bars, thereby realizing the automation of equidistant cutting of steel bars, facilitating operation and reducing dependence on technical workers.

[0017] 3. The inclined plate arranged on the movable block can make the inclined plate rise and fall synchronously with the movable block, and the protrusion arranged on the moving rod, when the movable block drives the inclined plate to move downward to the limit distance, the inclined surface of the inclined plate contacts and moves with the protrusion, so that the protrusion can push the moving rods on both sides to move in opposite directions under the action of the inclined surface of the inclined plate, so that the arc clamping plates move toward each other under the action of the moving rod to clamp and fix the steel bars, thereby improving the stability of the cutting wheel in cutting the steel bars and ensuring the quality of the steel bar cutting.

[0018] The coordinated use of the above-mentioned structure solves the problem that, in actual use, the existing device requires personnel to manually move the steel bars frequently for cutting operations, which is time-consuming and labor-intensive, and personnel frequently contact the equipment, posing certain safety hazards and easily leading to accidents, making it difficult to automatically move the steel bars equidistantly.
