Description

[0002] In municipal construction projects, steel bars, as an important building material, are widely used in the construction and reinforcement of various building structures. Steel bars refer to steel used for reinforced concrete and prestressed reinforced concrete. Their cross-sections are circular, and sometimes square with rounded corners. They include plain round steel bars, ribbed steel bars, and twisted steel bars. Steel bars for reinforced concrete refer to straight or coiled steel bars used for reinforced concrete reinforcement. In municipal construction projects, steel bars need to be bent according to the requirements of the installation area to facilitate the installation of the steel bars. In the bending action of the steel bars, a bending device needs to be used to bend the steel bars.

[0003] Most of the existing steel bar bending devices rely on manual or semi-automatic methods for feeding. This method has obvious problems. Manual feeding is not only labor-intensive, but also difficult to ensure the accuracy and consistency of feeding. Due to the instability of workers' operation, the feeding speed may be uneven, which in turn affects the accuracy and efficiency of bending. Therefore, we need to propose a steel bar bending device for municipal construction. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , the utility model provides a technical solution:

[0022] The steel bar bending device for municipal construction includes a positioning base plate 1, two groups of mounting plates 2 are symmetrically fixedly installed on the top of the positioning base plate 1, and a transmission component 3 for quantitatively feeding the steel bars to be bent is arranged on the opposite side of the two groups of mounting plates 2. The positioning base plate 1 is located on one side of the two groups of mounting plates 2 and is fixedly installed with four groups of pillars 4. The tops of the four groups of pillars 4 are fixedly connected with a mounting shell 5, and a plurality of groups of guide rollers 6 are rotatably installed on the inner walls of both sides of the mounting shell 5. A profile frame 7 is fixedly installed on the top of the positioning base plate 1, and a clamping component 8 for positioning the steel bars to be bent is arranged on the top of the profile frame 7. A fixing plate 9 is fixedly installed on one side of the upper surface of the positioning base plate 1, and a bending device body 10 is installed on one side of the fixing plate 9. The utility model can realize the control of the feeding speed and feeding amount of the steel bars by setting the positioning base plate 1, the mounting plate 2 and the transmission component 3, thereby ensuring the accuracy and consistency of the steel bar feeding, and the uniform feeding speed, thereby improving the bending efficiency and quality of the steel bars;

[0023] The transmission assembly 3 includes two groups of rotating rods 301, and the outer walls of the two groups of rotating rods 301 are fixedly sleeved with a conveying wheel 304. One end of the two groups of rotating rods 301 passes through one group of mounting plates 2 and is fixedly connected to a gear 302. The two groups of gears 302 are meshed with each other, and one end of one group of rotating rods 301 passes through the other group of mounting plates 2 and is connected to a driving motor 303.

[0024] By adopting the above case, the output shaft of the driving motor 303 can drive one set of rotating rods 301 to rotate, so that the other set of rotating rods 301 can be driven to rotate through two sets of mutually meshing gears 302, and then the two sets of conveying wheels 304 can be driven to rotate, so that the steel bars can be conveyed forward. In addition, by controlling the speed and number of rotations of the driving motor 303, the feeding speed and feeding amount of the steel bars can be controlled, so as to ensure the accuracy and consistency of the steel bar feeding, and the feeding speed is uniform, so as to improve the bending efficiency and quality of the steel bars;

[0025] The outer walls of the two groups of conveying wheels 304 are provided with steel bar receiving grooves 12, and the two groups of conveying wheels 304 are both made of rubber. A receiving cavity is formed between the two steel bar receiving grooves 12, and the steel bar to be bent passes through the receiving cavity. The rubber material has good wear resistance and can maintain good performance under long-term and high-intensity friction. The conveying wheels 304 need to frequently contact and convey the steel bars. The conveying wheels 304 made of rubber can effectively reduce wear and extend the service life. The surface of the rubber conveying wheels 304 is relatively rough, which increases the friction between the steel bars and the conveying wheels, thereby improving the stability during the conveying process. This helps to prevent the steel bars from sliding or deflecting during the conveying process, and ensures that the steel bars can accurately and stably enter the steel bar bending device body 10;

[0026] The driving motor 303 is fixedly mounted on a side wall of one of the mounting plates 2, one end of the output shaft of the driving motor 303 is fixedly connected to one end of one of the rotating rods 301, and the driving motor 303 is configured as a stepping motor;

[0027] The clamping assembly 8 includes an electric push rod 801, which is fixedly installed on the top of the profile frame 7. One end of the telescopic end of the electric push rod 801 passes through the profile frame 7 and is fixedly connected to a pressure plate 802. A groove is provided at the bottom of the pressure plate 802. Several groups of rotating rollers 11 are rotatably installed on the inner walls on both sides of the groove. The several groups of rotating rollers 11 are equidistantly arranged. The pressure plate 802 is located directly above the mounting shell 5. Rubber rings are sleeved on the outer walls of the several groups of rotating rollers 11 and the several groups of guide rollers 6. The telescopic end of the electric push rod 801 can drive the pressure plate 802 to move downward, thereby driving the several groups of rotating rollers 11 to move downward, and then the steel bars on the top of the guide rollers 6 can be pressed and positioned to avoid offset during subsequent bending of the steel bars, which is beneficial to improving the bending accuracy of the steel bars.
