Description

Technical Field

[0001] The utility model relates to the field of construction engineering, and particularly relates to a steel bar bender for construction engineering. Background Art

[0002] Construction engineering refers to the project formed by the construction of various housing buildings and their ancillary facilities and the installation of pipelines and equipment supporting them. In the current construction field, a large amount of steel bars are required in concrete structures. These steel bars need to be bent before being used in concrete structures. The hoop bender is a processing tool for bending steel bars, which can bend the steel bars into specified angles according to the usage requirements, so as to use the steel bars more conveniently in construction.

[0003] At present, there are some problems in the actual use of steel bar benders. When preparing for steel bar bending, workers usually need to carry the steel bars to the bender. During the bending process, workers need to hold one end of the steel bar by hand to ensure the stability of the steel bar during bending. However, when the steel bar is unevenly stressed during the bending process by the bender, the steel bar may splash and pop out, which may hurt the workers. Therefore, we propose a steel bar bender for construction engineering to solve the above problems. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a steel bar bender for construction engineering to solve the problems of automatic feeding, clamping and conveying.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A steel bar bender for construction engineering, including a main body mechanism and a shearing unit. A driving mechanism is installed beside the main body mechanism. The driving mechanism includes a conveying housing. Square grooves are symmetrically arranged at the top and bottom of one side of the conveying housing. A motor is arranged at the top of the square groove. The output end of the motor is installed with a roller through a connecting block. A return spring is arranged inside the connecting block and is connected to the square groove.

[0006] By adopting the above technical scheme, the conveying housing with symmetrically arranged square grooves improves the stability of the equipment and reduces the vibration during operation. The motor drives the roller through the connecting block, optimizing the force transmission and ensuring the accuracy and consistency of steel bar conveying. The cooperation of the return spring and the connecting block can accommodate steel bars of different diameters, thus extending the service life of the equipment.

[0007] Furthermore, the main body mechanism includes a machine body. One side of the machine body is fixedly connected with an armrest. The bottom of the machine body is fixedly connected with moving wheels, which are distributed in a matrix. The front side of the machine body is connected with a switch door through a hinge. There is a control button beside the switch door. The top of the machine body is equipped with a working disc. A shearing unit is fixedly installed beside the working disc. The other side of the machine body is fixedly installed with a support platform, and a driving mechanism is fixedly connected to the support platform.

[0008] By adopting the above technical solution, the moving wheels equipped at the bottom of the machine body are distributed in a matrix, which improves the stability and mobility of the equipment. The setting of the armrest enhances the stability during operation. The switch door and control button on the front side facilitate the operation and maintenance of the equipment. The combination of the working disc on the top and the shearing unit beside it improves the processing efficiency. The driving mechanism on the support platform is fixedly installed, making the overall structure more firm and ensuring the reliability and accuracy of the equipment during operation.

[0009] Furthermore, several limiting grooves are provided on the working disc, and limiting posts can be inserted into the limiting grooves. The bottom of the working disc is connected with a motor, which is located inside the machine body. The output end of the motor is connected with a transmission shaft, and the other end of the transmission shaft is connected with the working disc.

[0010] By adopting the above technical solution, the design of the limiting grooves and the insertable limiting posts provide high flexibility and accuracy. By adjusting the position of the limiting posts, the bending angle and radius of the steel bars can be easily set, so as to meet the processing requirements of steel bars of different specifications. The motor drives the working disc to rotate further, making the bending process more efficient and accurate.

[0011] Furthermore, an electric cylinder is installed at the top of the other side of the conveying shell. The output end of the electric cylinder penetrates through the conveying shell and is connected with a pressing block. A displacement sensor is installed on the inner wall of the conveying shell.

[0012] By adopting the above technical solution, the electric cylinder penetrates through the shell through the output end and is connected with the pressing block, so that the material can be accurately and evenly pressed during the conveying process, thereby improving the processing accuracy and consistency. The displacement sensor is installed on the inner wall of the shell, and can monitor the conveyed steel bars in real time.

[0013] Furthermore, the shearing unit includes a frame body. A hydraulic cylinder is installed on the frame body. The bottom of the frame body is hinged with a shearing arm, and the output end of the hydraulic cylinder is connected with the shearing arm.

[0014] By adopting the above technical solution, the output end of the hydraulic cylinder is connected to the shear arm hinged at the bottom. This configuration brings significant advantages. The hydraulic cylinder provides powerful shearing force, enabling the shear arm to cut various materials efficiently and precisely, improving the shearing effect and accuracy. The stable hinged structure and precise control ensure the stability and long-term reliability of the operation, significantly enhancing the production efficiency.

[0015] Furthermore, the cross-section of the conveying housing is a trapezoidal cross-section, with the direction of the roller being the long side and the direction of the electric cylinder being the narrow side. The outer surface of the roller is a rough surface.

[0016] By adopting the above technical solution, the direction of the roller is the long side, the direction of the electric cylinder is the narrow side, and the outer surface of the roller is rough. This setting optimizes the material transmission path, reduces friction and resistance, improves the smooth flow of materials, and the rough roller surface enhances the gripping force on the materials, preventing sliding and ensuring the stability during the conveying process. The electric cylinder in the narrow side direction cooperates with the trapezoidal housing, improving the accuracy of the system.
