Description

Technical Field

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

[0002] Construction engineering refers to the general term for various buildings and engineering facilities that provide the material and technical basis for human life and production. It is an important branch of construction projects, including but not limited to the construction of houses, bridges, roads, tunnels, ports, airports, water conservancy facilities, etc. Construction engineering is an organized, purposeful, large-scale economic activity of mankind, aiming to form comprehensive production capacity or exert engineering benefits.

[0003] After retrieval, in the prior art, the Chinese patent publication number: CN215998462U, authorization date: March 11, 2022, discloses a steel bar bender for construction engineering, which includes a workbench, a turntable, a shaft rod and a bending rod, and also includes an automatic pushing structure. The pushing structure includes a U-shaped plate, an electric telescopic rod and a clamping block. The U-shaped plate is arranged on the workbench, and the two clamping blocks are movably arranged on the U-shaped plate. A moving block is arranged at the end of the U-shaped plate, and the moving block is connected to the end of the electric telescopic rod. The electric telescopic rod is installed at the corner on the top of the workbench. By clamping the steel bar with the two clamping blocks and then under the action of the electric telescopic rod, the U-shaped plate is pushed to move on the workbench, realizing the function of automatically pushing the steel bar, improving the processing efficiency, and making the operation more convenient and labor-saving.

[0004] However, this device still has the following defects: Although it realizes the function of automatically pushing the steel bar and improves the processing efficiency, when the bender performs the steel bar bending operation, the common operation method is to simply and directly place the steel bar on the bender. This direct placement method, any slight vibration during the operation of the bender is sufficient to cause the position of the steel bar to shift, thereby causing deviation in the bending position, resulting in uneven bending results for each steel bar and making it difficult to meet strict process requirements. In addition, the limitation that the bender can only process a single steel bar at a time significantly restricts the smoothness and efficiency of the production line, leading to low overall work efficiency and making it difficult to meet the needs of large-scale production.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] An embodiment of the present utility model provides a steel bar bender for construction engineering, including a workbench 1. Exemplarily, as Figures 1-5 shown.

[0026] A concave block 2 is fixedly connected to the top of the workbench 1. A placement plate 3 is arranged on the top of the concave block 2. A cylinder 4 is fixedly connected to the top of the placement plate 3. A motor 5 is fixedly connected to the top of the workbench 1. The output end of the motor 5 is drivingly connected to a threaded rod 6. A threaded block 7 is threadedly connected to the surface of the threaded rod 6. The top of the threaded block 7 is fixedly connected to the placement plate 3. A limiting mechanism 8 is arranged in the inner cavity of the concave block 2. Clamping mechanisms 9 are arranged on both sides of the workbench 1.

[0027] The limiting mechanism 8 includes a long rod 81 fixedly connected to the inner cavity of the concave block 2. Two first moving blocks 82 are slidably connected to the surface of the long rod 81. A first spring 83 is sleeved on the surface of the long rod 81. Both ends of the first spring 83 are fixedly connected to the first moving blocks 82. Guide grooves 84 are opened on both sides of the top of the placement plate 3. Guide posts 85 are slidably connected to the inner cavities of the guide grooves 84. The bottoms of the guide posts 85 are fixedly connected to the first moving blocks 82.

[0028] The clamping mechanism 9 includes two convex blocks 91 fixedly connected to both sides of the top of the workbench 1. A connecting rod 92 is fixedly connected to the opposite sides of the two convex blocks 91. A second moving block 93 is slidably connected to the surface of the connecting rod 92. A second spring 94 is sleeved on the surface of the connecting rod 92. Both ends of the second spring 94 are fixedly connected to the convex block 91 and the second moving block 93 respectively. A clamping block 95 is fixedly connected to one side of the second moving block 93. A groove 96 is opened on one side of the clamping block 95.

[0029] Specifically, through the cooperation of the motor 5, the threaded rod 6, and the threaded block 7, it plays a role in driving the placement plate 3 and the cylinder 4 to move, enabling the guide post 85 to slide in the inner cavity of the guide groove 84. Thus, according to the user's needs, the steel bar can be bent to an appropriate angle. Through the setting of the first spring 83, it can accelerate the moving speed of the first moving block 82, making it more convenient for the placement plate 3 to reset. At the same time, it improves the stability of the guide post 85 during movement. Through the setting of the clamping block 95, multiple steel bars can be placed in the inner cavity of the groove 96 for bending, thereby improving the bending efficiency. Through the setting of the second spring 94, it can drive the second moving block 93 to slide on the surface of the connecting rod 92, and then make the two clamping blocks 95 move relatively, so as to clamp and fix the steel bar, making it not easy to shift during the clamping process.

[0030] Both sides of the bottom of the inner cavity of the concave block 2 are provided with sliding grooves 10, as Figures 1-3 shown.

[0031] The inner cavity of the sliding groove 10 is slidably connected with a slider 11. The top of the slider 11 is fixedly connected to the first moving block 82. The right side of the top of the workbench 1 is fixedly connected with a guide rod 12. The surface of the guide rod 12 is slidably connected with a guide block 13. The top of the guide block 13 is fixedly connected to the placement plate 3.

[0032] Specifically, through the cooperation of the sliding groove 10 and the slider 11, it plays a role in limiting the first moving block 82, improving the stability of the first moving block 82 during movement. Through the cooperation of the guide rod 12 and the guide block 13, it plays a role in supporting the placement plate 3, making the placement plate 3 not easy to shift when bending the steel bar, and improving the stability of the placement plate 3 during movement.

[0033] The surface of the motor 5 is sleeved with a mounting seat 14, as Figure 1 and Figure 2 shown.

[0034] Both sides of the top of the mounting seat 14 are threadedly connected with bolts. The motor 5 is detachably connected to the workbench 1 through bolts. Four support blocks 15 are fixedly connected to the four corners of the bottom of the workbench 1. The four support blocks 15 are symmetrically arranged. The inner cavity of the workbench 1 is slidably connected with a housing 16. The front surface of the housing 16 is fixedly connected with a handle 17.

[0035] Specifically, through the combined use of the mounting base 14 and bolts, the motor 5 is fixed, making it more stable when placed and not prone to self-rotation during operation. At the same time, it is convenient for users to disassemble and repair it. Through the setting of the support block 15, the bending machine is supported, improving the stability of the bending machine when placed. Through the combined use of the housing 16 and the handle 17, users can place the bent steel bars in the inner cavity of the housing 16 for collection. When a certain number is collected, it can be taken out.

[0036] The working principle of a steel bar bending machine for construction engineering proposed by an embodiment of the present utility model is as follows:

[0037] When the device is in use, by moving the clamping block 95, the clamping block 95 drives the second moving block 93 to move on the surface of the connecting rod 92. When the second moving block 93 moves, it will drive the second spring 94 to be compressed. Then, the user places both ends of the steel bar in the inner cavities of the two grooves 96. After the steel bar is placed, the resilience of the second spring 94 will drive the second moving block 93 to move, and the second moving block 93 drives the clamping block 95 to move, making the two clamping blocks 95 move relatively, so as to clamp and fix the steel bar, making its position not prone to deviation. By starting the motor 5, the output shaft of the motor 5 drives the threaded rod 6 to rotate. When the threaded rod 6 rotates, it will drive the threaded block 7 to move. When the threaded block 7 moves, it will drive the placement plate 3 to move. The placement plate 3 drives the guide block 13 to slide on the surface of the guide rod 12. When the placement plate 3 moves, it will drive the cylinder 4 to move. As the placement plate 3 continues to move, the guide post 85 will move in the inner cavity of the guide groove 84, thus starting to bend the steel bar. According to the user's needs, the steel bar can be bent to an appropriate angle. When the guide post 85 moves, it will drive the first moving block 82 to slide on the surface of the long rod 81. When the first moving block 82 moves, it will drive the slider 11 to slide in the inner cavity of the chute 10. At the same time, the first spring 83 is compressed. After the bending is completed, reverse-start the motor 5 to reset the placement plate 3.

[0038] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
