Description

Technical Field

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

[0002] In the field of construction, steel bars are usually needed. Steel bars play the role of bearing tensile stress in the structure, improving the ductility of the nodes of structural components in the building, and enhancing the earthquake resistance of the building. They also facilitate construction and sometimes act as lightning conductors, reducing the bearing capacity of the wall and increasing safety. They can be used to fix the position of steel hoops in the beam and form the steel skeleton in the beam. On the construction site, steel bars usually need to be cut into the required length.

[0003] Although most of the existing steel bar positioning and cutting devices have the working mode of uniformly cutting multiple steel bars, during use, most of them require that a batch of steel bars be cut first, and then the steel bars to be cut are placed on the cutting device before the steel bars can be cut. The function of continuous cutting of multiple steel bars is not possible. When cutting a large number of steel bars, a lot of time will be wasted in the process of loading the steel bars, thereby reducing the cutting efficiency of the steel bars.

[0004] Therefore, it is necessary to provide a steel bar positioning and cutting device for construction engineering to solve the above technical problems. Utility Model Content

The two ends of the spring 10 are respectively fixedly connected to the side opposite to the connecting plate 8 and the push plate 11. The cutting table 1 is provided with two adjustment components, a fixing component and a cutting component.

[0032] The adjusting component includes a U-shaped frame 13, which is fixedly connected to the top of the cutting table 1. Several rubber threaded sleeves 14 are fixedly embedded on the U-shaped frame 13. Through the setting of the rubber threaded sleeve 14, the friction between it and the threaded rod 2 15 can be increased, and the resistance to the rotation of the threaded rod 2 15 is increased, so as to avoid the steel bar and the top plate 16 from abutting against each other and driving the threaded rod 2 15 to rotate.

[0035] Working principle: During operation, steel bars of different lengths and thicknesses to be cut are placed inside a number of arc-shaped slots 4, and then the position of the corresponding top plate 16 can be adjusted according to the length of each steel bar to be cut, that is, the threaded rod 2 15 is manually rotated, and under the cooperation of the U-shaped frame 13 and the rubber threaded sleeve 14, the threaded rod 2 15 can drive the top plate 16 to move toward or away from the cutting table 1 to complete the adjustment of the position of the top plate 16, and then the motor 12 is started to drive the threaded rod 1 6 to rotate, and under the cooperation of the guide slot 5 , so that it drives the connecting frame 7, the connecting plate 8, the push rod 9 and the push plate 11 to move synchronously along the axial direction of the threaded rod 6, and can push the steel bars inside the arc groove 4 to move synchronously toward the position of the cutting knife 22 on one side, and in the process of moving, when one of the longer steel bars first abuts against the corresponding top plate 16 and continues to move, the corresponding push plate 11 and the push rod 9 are squeezed, so that one of the corresponding two springs 10 is squeezed and the other is stretched, so that the other push plates 11 can push the corresponding steel bars to continue to move until the other steel bars abut against the top plate 16;

[0036] Then start one of the hydraulic rods 18, so that it drives the corresponding lower pressure plate 19 and the rubber plate 20 to move downward synchronously, so that the steel bar to be cut can be fixed, and then start the corresponding motor 24 and the other hydraulic rod 18. After the motor 24 is started, it drives one of the cutting knives 22 to rotate, and under the action of the transmission mechanism 23, the other cutting knives 22 rotate synchronously. When the hydraulic rod 18 is started, the telescopic end extends, driving the mounting plate 21, the rotating cutting knife 22 and the motor 2 24 to move downward synchronously, and the rotating cutting knife 22 performs the cutting work of the steel bar. At the same time, in the process of the multiple steel bars being cut uniformly, after the connecting frame 7 moves to the side closer to the steel bar for cutting, the new steel bar to be cut can be placed on the other side of the connecting frame 7. After the multiple steel bars on one side are cut, by starting the motor 12 to reverse, the newly placed multiple steel bars can be pushed to move and perform the cutting work.
