Description

[0002] Rebar is a steel strip with a circular cross-section. Its main components are iron and carbon. It is widely used in construction projects to enhance the bearing capacity of buildings and improve their stability and earthquake resistance.

[0003] In order to meet the requirements of architectural design for structural components, workers usually use a steel bar bending machine to accurately and efficiently bend straight steel bars into specified shapes. The steel bar bending machine is mainly composed of a frame, a bending device, etc., which cooperates with the forming axis to rotate in an arc around the central axis to push the steel bar to bend.

[0004] Through long-term observation, it is found that when existing steel bars are bent, in order to prevent the steel bars from sliding or moving during the bending process, it is usually necessary to hold down the middle of the steel bar by hand. However, when bending shorter steel bars, it is difficult to hold down and support the ends of the steel bars due to the short length of the ends of the steel bars leaking out, resulting in the problem that the shorter steel bars are prone to sliding or moving during bending. Therefore, a steel bar bending equipment for construction projects is proposed to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] 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.

[0024] like Figure 1 , 2As shown in Figure 5, a steel bar bending equipment for construction engineering includes a bending machine body 1; an adjusting member 11 is installed on the top of the bending machine body 1; a fixing member 12 is fixedly connected to the top of the bending machine body 1; a slide plate 13 is slidably connected to the middle of the fixing member 12; a rotating shaft 14 is rotatably connected to the middle of the fixing member 12; a gear 15 is fixedly connected to the middle of the rotating shaft 14; the gear 15 and the slide plate 13 are meshed with each other; a handle 16 is provided at the end of the rotating shaft 14; a clamping plate 17 is fixedly connected to the end of the slide plate 13 ; The clamping plate 17 is U-shaped; a guide groove 18 matching the shape of the clamping plate 17 is opened in the middle of the adjusting member 11; when working, the staff needs to install the bending machine body 1 in the working area, and power on the bending machine body 1, and then use the tool to rotate the bolt in the middle of the adjusting member 11, and adjust the distance between the adjusting member 11 and the rotating axis in the middle of the bending machine body 1. By providing a fixing member 12 on the top of the bending machine body 1, the staff can first adjust the clamping plate 17 and the guide groove 18 when processing shorter steel bars. The distance between the grooves 18 is separated, and then the end of the steel bar is passed through the middle of the clamping plate 17 and the middle of the bending machine body 1 for fixing. After that, the staff can turn the handle 16 so that the rotation can drive the rotating shaft 14 and the gear 15 to rotate synchronously, so that the slide plate 13 slides in the middle of the fixing member 12, and the clamping plate 17 will gradually get stuck in the middle of the guide groove 18, and gradually clamp the steel bar in the middle, and reserve a little gap between the steel bar and the clamping plate 17, and then turn on the switch of the bending machine body 1, so that the output end in the middle of the bending machine body 1 can be rotated, and the middle of the steel bar is bent, and during the bending process, the end of the steel bar will be slowly pulled. This step is combined with a slidable slide plate 13 provided on the top of the bending machine body 1, which can reduce the problem that the staff is difficult to fix the steel bar when the bending machine body 1 is bending the shorter steel bar due to the shorter fulcrum of the steel bar end. It also reduces the problem of position sliding or movement of the shorter steel bar when bending, and improves the accuracy of steel bar processing.

[0025] like Figure 2 and 5As shown, a slide groove 2 is provided in the middle of the rotating shaft 14; a bayonet 21 is fixedly connected to the end of the handle 16; the handle 16 and the bayonet 21 are slidably arranged on the inner wall of the slide groove 2; the bayonet 21 is arranged in a polygonal shape; a bracket 22 is fixedly connected to the end of the fixing member 12; a clamping hole 23 matching the shape of the bayonet 21 is provided in the middle of the bracket 22; during operation, by providing a slide groove 2 in the middle of the rotating shaft 14, the staff can push the bayonet 21 after fixing the steel bar, so that the bayonet 21 and the handle 16 slide on the inner wall of the slide groove 2. The middle part is set as a polygon, so that the handle 16 can only slide horizontally on the inner wall of the slide groove 2. After continuing to push the latch 21, its end will gradually approach the position of the latch hole 23 until it is stuck in the latch hole 23. This step, combined with the polygonal latch 21, can fix the working position of the clamping plate 17, reduce the output end of the middle part of the bending machine body 1 during the bending process of the steel bars. The output end will generate a large pulling force, which will cause the staff to constantly push the middle part of the handle 16 in the opposite direction to fix it, thereby reducing the labor intensity of the staff. At the same time, the clamping plate 17 can be stored when it is not used.

[0026] like Figure 2 and 3 As shown, the end of the clamping plate 17 is fixedly connected to a fixed plate 3; a screw rod 31 is threadedly connected to the middle of the fixed plate 3; the bottom of the screw rod 31 is rotatably connected to an extrusion plate 32; the bottom of the extrusion plate 32 is arc-shaped; two groups of limit rods 33 are fixedly connected to the top of the extrusion plate 32; the limit rod 33 is slidably set in the middle of the fixed plate 3; during operation, by arranging the fixed plate 3 at the end of the clamping plate 17, when bending steel bars of different diameters, the staff can use a tool to rotate the screw rod 31, so that the screw rod 31 is in the process of rotation, and cooperates with the two groups of limit rods 33 sliding in the middle of the fixed plate 3, so that the extrusion plate 32 can move straight downward and adjust the spacing according to the diameter of the steel bar. This step cooperates with the arc-shaped extrusion plate 32 for controlling the spacing, which can improve the problem of angle deviation of the steel bar and affect the bending accuracy when bending thinner steel bars due to the large space in the middle of the clamping plate 17. Cooperating with the arc-shaped extrusion plate 32, the area after contacting with the round steel bar can be increased.

[0027] like Figure 4As shown, a support member 4 is fixedly connected to the top of the limit rod 33; two groups of cleaning cloths 41 are fixedly connected to the middle of the support member 4; an elastic rope 42 is fixedly connected to the inner wall of the cleaning cloth 41; the middle part of the cleaning cloth 41 is arranged in contact with the middle part of the screw rod 31; during operation, two groups of cleaning cloths 41 are arranged on the top of the limit rod 33. Under the action of the tension of the elastic rope 42, the middle part of the cleaning cloth 41 will be fitted together with the inner groove of the screw rod 31. Subsequently, during the rotation of the screw rod 31, the limit rod 33 will also move synchronously, and the cleaning cloth 41 fitted with the screw rod 31 will clean the impurities in the inner groove of the screw rod 31. This step, combined with the cleaning cloth 41 in contact with the screw rod 31, can improve the cleanliness of the middle part of the screw rod 31 and reduce the problem of more debris generated when bending the steel bar and adhering to the middle part of the screw rod 31, resulting in greater resistance when the screw rod 31 is rotated later.

[0028] like Figure 2 As shown, a cleaning knife 5 is fixedly connected to the end of the clamping plate 17; the end of the cleaning knife 5 is inclined; a storage box 51 is fixedly connected to the middle of the adjusting member 11; the storage box 51 is arranged at the end of the guide groove 18; during operation, by arranging the cleaning knife 5 at the end of the clamping plate 17, when the clamping plate 17 moves and gradually approaches the middle of the guide groove 18, the inclined cleaning knife 5 will remove the impurities attached to the inside of the guide groove 18, and then transfer them to the inside of the storage box 51 for collection. This step cooperates with the cleaning knife 5 to reduce the accumulation of more metal debris on the inner wall of the guide groove 18. At the same time, the hollow storage box 51 can store impurities, reducing the direct drop of some impurities on the middle of the slide plate 13, causing the slide plate 13 to get stuck when it is meshing with the gear 15.

[0029] like Figure 2 As shown, the inner wall of the clamping plate 17 is rotatably connected with multiple groups of rotating balls 6; the rotating balls 6 are arranged in a circular array on the inner wall of the clamping plate 17; when working, multiple rotating balls 6 are arranged on the inner wall of the clamping plate 17, so that the middle part of the rotating balls 6 will contact with the fixed steel bars. This step cooperates with the rotating balls 6 to reduce the problem that the processed steel bars are clamped tightly, resulting in the problem that the end of the steel bar is difficult to be pulled when the steel bar is bent at the middle output end of the bending machine body 1.

[0030] like Figure 2 As shown, the end of the handle 16 is rotatably connected to a friction pad 7; the middle part of the friction pad 7 is recessed; during operation, by providing the friction pad 7 at the end of the handle 16, this step cooperates with the rotatable friction pad 7 to reduce the problem of the staff needing to frequently change the holding angle during the rotation of the handle 16, and the groove in the middle part of the friction pad 7 can be used to increase the friction between the staff's hand and the friction pad 7.

[0031] Working principle: after the bending machine body 1 is installed in the working area and the bending machine body 1 is powered on, the bolt in the middle of the adjusting member 11 is rotated with the help of a tool, and the distance between the adjusting member 11 and the rotating shaft in the middle of the bending machine body 1 is adjusted. By setting a fixing member 12 on the top of the bending machine body 1, when processing shorter steel bars, the staff can first separate the distance between the clamping plate 17 and the guide groove 18, and then pass the end of the steel bar through the middle of the clamping plate 17 and the middle of the bending machine body 1 for fixing. After completion, the staff can rotate the handle 16, so that the rotation can drive the rotating shaft 14 and the gear 15 to rotate synchronously, so that the slide plate 1 3 slides in the middle of the fixing member 12, and the clamping plate 17 is gradually stuck in the middle of the guide groove 18, and the steel bar in the middle is gradually clamped, and a little gap is reserved between the steel bar and the clamping plate 17. Then, after turning on the switch of the bending machine body 1, the output end in the middle of the bending machine body 1 can be rotated, and the middle of the steel bar is bent. In the bending process, the end of the steel bar is slowly pulled. By opening a slide groove 2 in the middle of the rotating shaft 14, the staff can push the latch 21 after fixing the steel bar, so that the latch 21 and the handle 16 slide on the inner wall of the slide groove 2. Because the middle of the latch 21 is a polygonal setting, the handle 16 can be pushed. The hand 16 can only slide horizontally on the inner wall of the slide groove 2. After continuing to push the latch pin 21, its end will gradually approach the latch hole 23 until it is stuck in the latch hole 23. By providing a fixing plate 3 at the end of the clamping plate 17, when bending steel bars of different diameters, the staff can use a tool to rotate the screw rod 31, so that the screw rod 31 can cooperate with two groups of limit rods 33 sliding in the middle of the fixing plate 3 during the rotation process, so that the extrusion plate 32 can move straight downward and adjust the spacing according to the diameter of the steel bar. By providing two groups of cleaning cloths 41 on the top of the limit rods 33, the cleaning cloths 41 can be adjusted under the action of the tension of the elastic ropes 42. The middle part will fit together with the inner groove of the screw 31, and then during the rotation of the screw 31, the limit rod 33 will also move synchronously, and the cleaning cloth 41 fitted with the screw 31 will clean the impurities in the inner groove of the screw 31, and a cleaning knife 5 is provided at the end of the clamping plate 17, so that when the clamping plate 17 moves and gradually approaches the middle of the guide groove 18, the inclined cleaning knife 5 will remove the impurities attached to the inside of the guide groove 18, and then transfer them to the inside of the storage box 51 for collection, and a plurality of rotating balls 6 are provided on the inner wall of the clamping plate 17, so that the middle part of the rotating ball 6 will contact the fixed steel bar, and a friction pad 7 is provided at the end of the handle 16.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
