Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel bar bending, in particular to a steel bar bending device for construction engineering. Background Art
[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. The cross section of the rebar is round, and sometimes square with rounded corners. Rebar processing generally goes through four processes: rust removal, straightening, cutting, and forming. It is mainly used for various large, heavy, light thin-walled and high-rise building structures. It is divided into three types: plain round rebar, ribbed rebar, and twisted rebar.
[0003] The existing patent CN220127474U discloses a steel bar bending device for construction projects. The motor is controlled to drive the threaded rod fixedly connected to the output shaft end of the motor to rotate in the inner wall of the base. The slider is connected to the outer edge of the threaded rod by a slider, so that the threaded rod rotates and drives the slider to move, thereby driving the pressure block fixedly connected to the top of the slider to move, so that the steel bar can be bent easily. The upper and lower plates connected to the outer edge of the rotating rod are driven to move by rotating the rotating rod, so that the upper and lower plates move in the inner wall of the fixed block. The directions of the inner threads of the upper and lower plates are opposite, so that the upper and lower plates move in opposite directions, thereby fixing the steel bar with the upper and lower plates to prevent the steel bar from shifting during the bending process.
[0004] The above technical solution solves the problem that it is inconvenient to bend steel bars of different sizes during use, which reduces the practicability of the device, and fixes the steel bars by placing rings and clamping blocks, which causes the steel bars to move under force during use, resulting in reduced stability of the steel bars during the bending process. However, the following deficiencies still exist, such as: when the steel bars to be processed are bent under force, there may be a certain degree of deflection at both ends of the steel bars. At this time, the reaction force of the steel bars may squeeze the upper and lower plates, causing local deformation of the upper and lower plates, which is not conducive to the long-term operation of the device in the later stage and greatly reduces the service life of the device.
[0005] Therefore, the utility model provides a steel bar bending device for construction engineering. Utility Model Content
[0006] The purpose of the utility model is to solve the shortcomings of the prior art and provide a steel bar bending device for construction engineering.
[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a construction engineering steel bar bending device, including a workbench, a bending assembly is arranged on the workbench, the bending assembly includes a first gear, a first rotating shaft is penetrated by the first gear and is fixedly connected to the output end of the motor, a second gear is movably connected to one end of the first gear, a second rotating shaft is penetrated by the second gear, the second rotating shaft is movably connected to the curved gear plate at one end away from the first gear, a bending column is fixedly connected to the upper end of the second rotating shaft, a first limiting column is fixedly connected to the upper and lower ends of the bending column, the second rotating shaft penetrates the first limiting column and is fixedly connected to the bending column, and a push-pull assembly is arranged on the workbench.
[0008] As a preferred embodiment, the push-pull assembly includes an electric telescopic rod, a first rotating block is fixedly connected to the top of the electric telescopic rod, one end of the first rotating block is rotatably connected to a push-pull column, the push-pull column is rotatably connected to a second rotating block and a third rotating block at one end away from the electric telescopic rod, the bottom end of the second rotating block is fixedly connected to a connecting plate, the bottom end of the connecting plate is fixedly connected to a second limit block, the connecting plate is fixedly connected to a fixed plate at one end away from the electric telescopic rod, and the workbench is fixedly connected to the first limit block.
[0009] The technical effect of adopting the above further scheme is: opening the electric telescopic rod to adjust the height of the electric telescopic rod so as to push the push-pull column to move toward the side close to the baffle. Because the push-pull column is connected to the second rotating block, the fixed plate, the connecting plate and the second limit block, the push-pull column pushes the fixed plate to move toward the side close to the baffle, which is convenient for adjusting the distance between the fixed plate and the baffle according to the diameter of the steel bars to be processed, so that the device can adapt to steel bars of different diameters to be processed, thereby increasing the versatility of use of the device.
[0010] As a preferred embodiment, a baffle is fixedly connected to the workbench, a resistance column is fixedly connected to the workbench, a second limiting column is fixedly connected to the top and bottom of the resistance column, and support legs are fixedly connected to the four corners of the bottom end of the workbench.
[0011] As a preferred embodiment, a groove is provided on the workbench, the width of the groove is the same as the diameter of the second rotating shaft, the second rotating shaft slides in the groove, the diameters of the bending column and the first limiting column are larger than the width of the groove, the distance between the curved gear plate and the center point is larger than the distance between the groove and the center point, the curved gear plate is fixedly connected to the bottom end of the workbench, and the curved gear plate has the same height as the second gear and the first rotating shaft.
[0012] The technical effect of adopting the above-mentioned further scheme is: the first limiting column can slide back and forth in the groove, exerting a force on the steel bars to be processed, and the second gear and the gear of the curved gear plate are staggered and intersected, so the second gear rotates on the curved gear plate along the curvature of the curved gear plate, and the second gear drives the second rotating shaft, the bending column and the first limiting column to move synchronously, exerting a force on the steel bars to be processed, causing the steel bars to bend.
[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
[0014] The utility model provides a bending component, and before use, the staff can first slide the bending column and the first limiting column to the top of the left side, so that the bending column and the first limiting column are horizontally placed on the fixed plate as a whole, and the steel bars to be processed are placed in the gap formed between the fixed plate and the baffle plate in sequence. When the device starts to be used, the motor is turned on, and the motor drives the first rotating shaft to start rotating. Because the first rotating shaft and the second gear are misaligned and intersected, the first rotating shaft drives the second gear to start rotating. Because the second gear and the curved gear plate gear are misaligned and intersected, the second gear rotates on the curved gear plate along the curvature of the curved gear plate, and the second gear drives the second rotating shaft to start rotating. The shaft, the bending column and the first limit column move synchronously to apply a force to the steel bar to be processed, so that the steel bar is bent. In addition, the setting of the fixed plate and the baffle can well limit the movement of the steel bar to be processed, and prevent the steel bar from being deflected by the reaction force during the bending process, causing damage to the equipment, thereby reducing the service life of the equipment. By setting the bending component, the electric telescopic rod is opened to adjust the height of the electric telescopic rod to push the push-pull column to move to the side close to the baffle, so that the distance between the fixed plate and the baffle can be adjusted according to the diameter of the steel bar to be processed, so that the device can adapt to steel bars of different diameters to be processed, thereby increasing the versatility of use of the device.

[0021] 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.
[0022] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a steel bar bending device for construction engineering, including a workbench 1, a bending assembly 3 is arranged on the workbench 1, the bending assembly 3 includes a first gear 31, the first gear 31 is penetrated by a first rotating shaft 33 and is fixedly connected to the output end of a motor 32, one end of the first gear 31 is movably connected to a second gear 34, the second gear 34 is penetrated by a second rotating shaft 35, the second rotating shaft 35 is movably connected to a curved gear plate 36 at one end away from the first gear 31, a bending column 37 is fixedly connected to the upper end of the second rotating shaft 35, the first limiting column 38 is fixedly connected to the upper and lower ends of the bending column 37, the second rotating shaft 35 penetrates the first limiting column 38 and is fixedly connected to the bending column 37, and a push-pull assembly 4 is arranged on the workbench 1.
[0023] Furthermore, if Figure 1 and Figure 4As shown: the push-pull assembly 4 includes an electric telescopic rod 41, the top of the electric telescopic rod 41 is fixedly connected to a first rotating block 42, one end of the first rotating block 42 is rotatably connected to a push-pull column 43, the push-pull column 43 is rotatably connected to a second rotating block 44 and a third rotating block 49 at one end away from the electric telescopic rod 41, the bottom end of the second rotating block 44 is fixedly connected to a connecting plate 46, the bottom end of the connecting plate 46 is fixedly connected to a second limiting block 48, the end of the connecting plate 46 away from the electric telescopic rod 41 is fixedly connected to a fixed plate 45, and the workbench 1 is fixedly connected to the first rotating block 44 and the third rotating block 49. The limit block 47 adjusts the height of the electric telescopic rod 41 by opening the electric telescopic rod 41, thereby pushing the push-pull column 43 to move toward the side close to the baffle 5. Because the push-pull column 43 is connected to the second rotating block 44, the fixed plate 45, the connecting plate 46 and the second limit block 48, the push-pull column 43 pushes the fixed plate 45 to move toward the side close to the baffle 5, which is convenient for adjusting the distance between the fixed plate 45 and the baffle 5 according to the diameter of the steel bars to be processed, so that the device can adapt to steel bars of different diameters to be processed, thereby increasing the versatility of use of the device.
[0024] The above schemes still have problems to be dealt with, such as Figure 1 - Figure 2 As shown: in this solution, a baffle 5 is fixedly connected to the workbench 1, a resistance column 7 is fixedly connected to the workbench 1, a second limiting column 6 is fixedly connected to the top and bottom of the resistance column 7, and support legs 2 are fixedly connected to the four corners of the bottom end of the workbench 1.
[0025] The above solutions still have the problem of how to deal with the force applied to the steel bars, such as Figure 1 - Figure 3 As shown: In this scheme, a groove 11 is opened on the workbench 1, the width of the groove 11 is the same as the diameter of the second rotating shaft 35, the second rotating shaft 35 slides in the groove 11, and the diameters of the bending column 37 and the first limiting column 38 are larger than the width of the groove 11, so that the first limiting column 38 can slide back and forth in the groove 11 to apply force to the steel bars to be processed.
[0026] In the above schemes, there is still the problem of how to generate the force, such as Figure 2 and Figure 3 As shown: in this scheme, the curved gear plate 36 is fixedly connected to the bottom end of the workbench 1, the curved gear plate 36 has the same height as the second gear 34 and the first rotating shaft 33, the distance between the curved gear plate 36 and the center point is greater than the distance between the groove 11 and the center point, and the second gear 34 and the curved gear plate 36 are misaligned and intersected, so the second gear 34 rotates on the curved gear plate 36 along the curvature of the curved gear plate 36, and the second gear 34 drives the second rotating shaft 35, the bending column 37 and the first limiting column 38 to move synchronously, exerting a force on the steel bars to be processed, so that the steel bars are bent.
[0027] Working principle:
[0028] like Figure 1-4 As shown:
[0029] When in use: the staff can first slide the bending column 37 and the first limiting column 38 to the top of the left side, so that the bending column 37 and the first limiting column 38 are overall horizontal above the fixed plate 45, and the steel bars to be processed are placed in the gap formed between the fixed plate 45 and the baffle 5 in sequence. At this time, the height of the electric telescopic rod 41 can be adjusted by opening the electric telescopic rod 41 to push the push-pull column 43 to move closer to the baffle 5. Because the push-pull column 43 is connected to the second rotating block 44, the fixed plate 45, the connecting plate 46 and the second limiting block 48, the push-pull column 43 pushes the fixed plate 45 to move closer to the baffle 5, which is convenient for adjusting the fixed plate 4 according to the diameter of the steel bars to be processed. 5 and the baffle plate 5, the part to be bent is moved to contact the surface of the bending column 37, the motor 32 is turned on, the motor 32 drives the first shaft 33 to start rotating, because the first shaft 33 and the second gear 34 are misaligned and intersected, the first shaft 33 drives the second gear 34 to start rotating, and because the second gear 34 and the curved gear plate 36 are misaligned and intersected, the second gear 34 rotates on the curved gear plate 36 along the curvature of the curved gear plate 36, the second gear 34 drives the second shaft 35, the bending column 37 and the first limiting column 38 to move synchronously, and a force is applied to the steel bar to be processed to bend the steel bar. After the end, the staff will take the processed steel bar out of the equipment.
