Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, and in particular relates to a building steel bar cutting device. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and torsion steel bars. Steel bars mainly bear tensile stress in concrete. Deformed steel bars have greater bonding ability with concrete due to the effect of the ribs, and can therefore better withstand the effects of external forces. Rebars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.

[0003] During the cutting process, existing steel bars may deflect or shift due to the cutting force, resulting in poor cutting effect; when cutting the steel bars, manual support is required, which may cause hand pain for a long time; and the existing construction steel bar cutting device is inconvenient to cut multiple steel bars at the same time, resulting in low work efficiency.

[0021] During operation, the user places the steel bars between the two lower jackets on the same side, and drives the upper jacket to move downward along the guide rod and contact with the lower jacket through the push of the electric push rod, thereby clamping and fixing the steel bars to be cut. When the steel bars are cut, the electric push rod drives the upper jacket to move upward along the guide rod, and the upper jacket moves upward and out of contact with the steel bars. At this time, the cut steel bars can be collected, and then the electric push rod is closed. The entire process of this device can realize automated steel bar cutting operations, improve efficiency and ensure the accuracy of cutting.

[0022] In the above technical solution, further, the truncation component includes:

[0023] Hydraulic cylinders are arranged on the left and right sides of the top of the base plate;

[0024] A mounting frame is arranged between the telescopic rods of the two hydraulic cylinders;

[0025] The cutter is arranged on the mounting frame by means of bolt connection, and the cutter is located on the upper side of the workbench.

[0026] In the present technical solution, the hydraulic cylinder is arranged on the left and right sides of the top of the base plate. The hydraulic cylinder is a power device generated by liquid pressure, which can be used to promote the movement of the telescopic rod. The function of the hydraulic cylinder is to provide force to perform the cutting operation. The mounting frame is arranged between the telescopic rods of the two hydraulic cylinders. The purpose of the mounting frame is to provide support and positioning to ensure that the telescopic movement of the hydraulic cylinder can be effectively transmitted to the cutter. The cutter is arranged on the mounting frame by bolt connection and is located on the upper side of the workbench. The cutter is part of the cutting assembly, and its function is to actually cut the steel bars.

[0027] Working process: the operator places the steel bar to be cut on the lower clamping sleeve, and drives the upper clamping sleeve through the electric push rod to fix and clamp the steel bar to ensure that it is within the working range of the cutter. The hydraulic cylinder starts and begins to extend and retract, pushing the mounting frame downward. The movement of the mounting frame causes the cutter to drop accordingly, contacting the steel bar to be cut, and cutting the steel bar to the required length. The hydraulic cylinder contracts, and the mounting frame and cutter return to the initial position to complete a cutting operation. The entire process is transmitted through hydraulic force to ensure accurate cutting of the steel bar, so that it can achieve the characteristics of automation and efficiency, which is suitable for the needs of cutting steel bars to a fixed length in construction.

[0034] The elastic member is sleeved on the connecting rod and arranged between the sliding sleeve and the mounting frame.

[0035] In the present technical scheme, after the steel bar is fixed and clamped by the lower jacket and the upper jacket, the lower jacket raises the height of the steel bar on the workbench, resulting in no support for the steel bar. When the cutter performs the cutting work, the steel bar is easily deformed, affecting the quality of the steel bar. Therefore, a support plate is arranged on the lower side of the cutter, and the support plate is located on the workbench, so as to support the fixed steel bar. When the cutter descends, the mounting frame drives the connecting rod to move downward along the sliding sleeve and the support plate, and the elastic member is compressed. The cutter contacts the steel bar to be cut and cuts the steel bar to the required length. The support plate can support the steel bar to prevent the steel bar from being deformed, thereby improving the cutting quality of the steel bar. After the steel bar is cut, the mounting frame and the cutter return to the initial position, and the mounting frame drives the connecting rod to move upward along the sliding sleeve and the support plate back to the initial position, and the elastic member is reset accordingly. The elastic member serves as a connecting component between the mounting frame and the sliding sleeve, so that the support plate can move with the cutter, so that the steel bar to be cut can be supported, the steel bar can be prevented from being deformed during the cutting process, and the cutting quality of the steel bar can be improved.

[0036] In any of the above technical solutions, further, the elastic member is a connecting spring.

[0037] In the technical solution, the elastic member is used as a connecting spring so that the support plate can move along with the cutter, thereby facilitating adjustment of the cut length of the steel bar.

[0038] In any of the above technical solutions, further, an adjustment component is included, and the adjustment component includes:

[0039] Electric slide rails are arranged on the left and right sides of the top of the bottom plate;

[0040] The electric slider is slidably arranged on the electric slide rail through a moving part, and the electric slider is connected to the hydraulic cylinder.

[0041] In the present technical solution, when it is necessary to adjust the length of the steel bar cut, the electric slide rail is started, the electric slider drives the hydraulic cylinder to move in the forward and backward directions, the hydraulic cylinder drives the mounting frame to move, the mounting frame drives the cutter and the connecting rod to move, and the mounting frame drives the sliding sleeve and the support plate to move through the connecting spring, and the cutter and the support plate are adjusted to the position where the steel bar needs to be cut, and then the electric slide rail is closed. At this time, the hydraulic cylinder drives the cutter to perform the work of cutting the steel bar, thereby cutting the steel bar into the required length. In this way, the position of the steel bar cut can be adjusted, which is convenient for cutting the steel bar into the required length, so that the steel bar can be used according to the required length.

[0042] The beneficial effects of the utility model are:

[0043] 1. The user places the steel bar on the lower clamping sleeve, and drives the upper clamping sleeve downward through the electric push rod to clamp and fix the steel bar to be cut. The whole process of this device can realize the automatic steel bar cutting operation, improve efficiency and ensure the accuracy of cutting;

[0044] 2. The mounting frame is driven downward by the hydraulic cylinder. The movement of the mounting frame causes the cutter to descend and contact the steel bar to be cut, cutting the steel bar into the required length.
