[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete, and its cross-section is circular. With the rapid development of science and technology, the construction industry is also developing rapidly. A large number of rebars will be used in construction. When using rebars, not all straight rebars are used. Sometimes the rebars are bent. On construction sites, rebar bending machines are common equipment. Their function is to bend straight rebars. Rebar bending devices are divided into manual bending and electric bending. Most of the existing bending devices can only place rebars of the same size in the position where rebars are placed. When the size of the rebar changes, the rebar bending device can no longer completely fix the rebar, resulting in the rebar may be offset during the transportation process, which causes the bending position of the rebar to deviate when it is bent. The sizes of the rebars bent from the same batch are different, affecting later use.

DETAILED DESCRIPTION
[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] like Figure 1 As shown, a steel bar bending device for construction engineering comprises an operating platform 1, the four corners of the lower end of the operating platform 1 are fixedly connected to support rods 2, the front part of the lower end of the operating platform 1 is fixedly connected to a shell 1 3, the shell 1 3 and the operating platform 1 are fixedly connected to a shell 2 8, a through slot is provided at the front part of the upper end of the operating platform 1, a bending component 7 is rotatably connected inside the through slot, a cutting knife 6 is provided at the middle part of the upper end of the operating platform 1, four transport components 5 are rotatably connected to the rear part of the upper end of the operating platform 1, a number of symmetrical rollers 4 are rotatably connected to the front and rear parts of the upper end of the operating platform 1, and the two support rods 2 on the left are higher than the two support rods 2 on the right.
[0026] During the specific implementation of the utility model, the steel bar is firstly drawn out from the steel bar coil and inserted between the plurality of rollers 4 located at the rear, and then the transport component 5 is started to transport the steel bar forward. During this process, the transport component 5 will autonomously clamp the steel bar according to the actual diameter of the steel bar. When the steel bar is transported to the upper part of the bending component 7, the bending component 7 will also autonomously clamp the steel bar according to the diameter of the steel bar to ensure the uniformity of the front and rear clamping and the same bending position and angle as much as possible. Then the bending component 7 is started to start bending. After the bending is completed, the cylinder 32 is used to drive the cutting knife 6 and the bending component 7 to descend to cut the bent steel bar. The slightly inclined setting of the operating table 1 can make the cut steel bar slowly slide down under the action of its own gravity and be collected by the collection frame.
[0027] Specifically, in order to realize the autonomous clamping and bending of steel bars of different diameters, refer to Figure 2 and Figure 5The transport assembly 5 includes four rotating shafts 54, the two rotating shafts 54 located on the left and the two rotating shafts 54 located on the right are connected together through two pulleys and a transmission belt, the two rotating shafts 54 located at the front are connected together through two meshing gears 52, a motor 53 is fixedly connected to the middle of the lower end of one of the gears 52, and the upper ends of the four rotating shafts 54 are fixedly connected to the telescopic assembly 51;
[0028] For further information, see Figure 2 The lower ends of the four rotating shafts 54 are rotatably connected to the second housing 8, and the upper ends of the four rotating shafts 54 pass through the second housing 8 and extend to the lower part of the telescopic component 51;
[0029] For further information, see Figure 5 The telescopic assembly 51 includes two receiving plates 511, and a connecting column 512 is fixedly connected to the middle of one end of the two receiving plates 511 close to each other. A plurality of telescopic members 513 are fixedly connected to the outer surface of the connecting column 512 in an annular array, and a friction plate 515 slidably connected to the two receiving plates 511 is fixedly connected to the side of the plurality of telescopic members 513 away from the connecting column 512;
[0030] The telescopic member 513 is composed of a telescopic rod and a spring, so as to facilitate the distance between the friction plate 515 and the connecting column 512 to be shortened and extended smoothly.
[0031] The spacing between the plurality of rollers 4 located on the left side and the plurality of rollers 4 located on the right side can smoothly pass the steel bars with the maximum diameter that the transport assembly 5 can pass, without affecting the transport of the steel bars.
[0032] It can be seen that when the steel bar is inserted between the rollers 4 located at the rear, the steel bar is pushed manually. When the rollers 4 on both sides contact the steel bar, they will rotate under the action of friction force, which is convenient for the smooth movement of the steel bar. Then, the motor 2 53 and the motor 1 73 are started. When the steel bar reaches between the friction plates 515 and contacts the friction plates 515, if the diameter of the steel bar is greater than the minimum spacing between the friction plates 515 on the left and right sides, the steel bar will squeeze the friction plates 515 in contact with the steel bar, and the friction plates 515 will squeeze the telescopic parts 513 accordingly, so that the spacing between the two symmetrical friction plates 515 on the left and right sides becomes larger, and the larger steel bar is clamped smoothly, and the clamping is realized by self-expansion and adjustment according to the size of the steel bar. This process ensures the continuity of the device operation, and does not require manual operation, and steel bars with different diameters can be directly replaced for processing;
[0033] As the motor 2 53 is started, the gear 2 52 on the same side will be driven to rotate clockwise, and under the action of the two meshing gears 2 52, the gear 2 52 on the other side will be driven to rotate counterclockwise, so that the rotating shaft 54 on the same side as the gear 2 52 will rotate in the same direction as the gear 2 52 on the same side, and under the action of the pulley and the transmission belt, the two rotating shafts 54 located on the rear side can be driven to rotate. At this time, it can be found that the two rotating shafts 54 on the left side rotate counterclockwise together, and the two rotating shafts 54 on the right side rotate clockwise, which can drive the receiving plate 511 on the same side to rotate in the same direction, and can smoothly drive the multiple friction plates 515 to rotate together. According to the opposite rotation directions of the receiving plates 511 on the left and right sides, the steel bars can be driven to move forward smoothly under the action of the friction force of the multiple friction plates 515.
[0034] Specifically, in order to ensure that the angle and position of the bent steel bars are consistent, refer to Figure 2 , Figure 3 and Figure 4 The bending assembly 7 includes a clamping assembly 71, a bending column 75 is fixedly connected to the outer side of the upper part of the clamping assembly 71, and a gear ring 74 is fixedly connected to the lower part of the clamping assembly 71. The outer surface of the gear ring 74 is meshedly connected to a gear 1 72, and the lower end of the gear 1 72 is fixedly connected to a motor 1 73;
[0035] Further, referring to the figure, a slide plate 31 is slidably connected to the inner surface of the housing 1 3, and a cylinder 32 is fixedly connected to the slide plate 31 and the housing 1 3. The left side and the right side of the lower end of the cutting knife 6 are fixedly connected to the slide plate 31 through a connecting rod penetrating the operating table 1, and the motor 1 73 is fixedly connected to the upper end of the slide plate 31;
[0036] Further, referring to the figure, the clamping assembly 71 includes a rotating disk 711 and two springs 713. The middle part of the rotating disk 711 is rotatably connected to a fixing member 715. The upper end of the fixing member 715 is symmetrically slidably connected to two clamping plates 712. The upper end of the fixing member 715 is provided with a slide groove that runs through the inside of the fixing member 715. The lower ends of the two clamping plates 712 are fixedly connected to two connecting rods 714. The two connecting rods 714 on the same side are connected together by a spring 713 and are slidably connected to the slide groove.
[0037] Further, referring to the figure, the turntable 711 is rotatably connected to the through slot opened at the upper end of the operating table 1, and the fixing member 715 is fixedly connected to the slide plate 31.
[0038] The initial distances between the two clamping plates 712 and the receiving plates 511 on the left and right sides are uniform.
[0039] It can be seen that when the steel bar is smoothly transported to between the two clamping plates 712 through the middle roller 4, if the transport component 5 adjusts the clamping of the steel bar, the steel bar with a larger diameter will squeeze the clamping plates 712 on both sides. At this time, under the action of the spring 1 713, the two clamping plates 712 will move away from each other with the cooperation of the four connecting rods 1 714, so as to smoothly clamp the steel bar and maintain the uniformity of the front and rear clamping, so that the steel bar will not deviate in the horizontal direction during transportation, further ensuring that the bending angle and size of the steel bar are consistent, so that the size of the finished steel bar after bending is uniform, and it is convenient for it to be put into use later;
[0040] As the motor 73 is started, the gear 72 will be driven to rotate, which can then drive the gear ring 74 to rotate, and the turntable 711 can be driven to rotate. At this time, the fixing part 715 remains stationary, and the bending column 75 can be used to bend the steel bar. The length and direction of the bending are controlled by the motor 73 and the motor 2 53 through programming. After the bending is completed, the motor 73 is stopped, and the cylinder 32 is started to drive the slide plate 31 to slide downward on the inner surface of the shell 3, which can drive the bending assembly 7 to slide downward as a whole, and drive the cutting knife 6 to move downward. When the bending assembly 7 is placed inside the same side, the motor 2 53 is used to drive the steel bar to move backward. When the position where the steel bar needs to be cut drops to the position of the cutting knife 6, the cutting knife 6 just drops to this position to cut it. The slightly inclined setting of the operating table 1 can make the cut steel bar slowly slide down under the action of its own gravity and can be collected by the collection frame.
[0041] It should be noted that the specific installation method, circuit connection method and control method of the motor 1 73, cylinder 32 and motor 2 53 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
