Technical Field

[0001] The utility model relates to the technical field of steel bar processing, in particular to a steel bar bender capable of automatically feeding materials. Background Art

[0002] A civil air defense door is a safety device used in civil air defense projects, mainly used to prevent the intrusion of explosion waves and harmful substances; a large number of steel bars are required in the manufacturing process to enhance its structure and load-bearing capacity, and the designs and sizes are different, and the required shapes of the steel bars inside are different. A steel bar bender can help bend straight steel bars into the required angles and shapes, so as to facilitate the construction of the frame structure and support system of the civil air defense door.

[0003] The reference patent name is: Steel Bar Bender (Patent Publication No.: CN218080133U, Patent Publication Date: December 20, 2022), which includes an operating table, a working disk and a resisting plate. Both the working disk and the resisting plate are connected to the top wall of the operating table, and a placing groove body for placing steel bars is connected to the side wall of the resisting plate close to the working disk. Before bending the steel bar, the steel bar is placed in the placing groove body, and then the machine is started to bend the steel bar. The placing groove body can ensure that the axis of the steel bar is perpendicular to the axis of the bending shaft, so as to ensure that the processed steel bar meets the processing requirements.

[0004] However, when implementing the above technical solutions, the following problems exist: The above solutions can achieve the perpendicularity of the axis of the steel bar and the axis of the bending shaft when the steel bar bender bends the steel bar, and ensure the bending angle. However, in the above solutions, it is difficult to quickly take out the steel bar after bending. In the above solutions, the steel bar is fixed on the surface of a certain structure through a groove for fixing the steel bar. Due to the existence of the groove, it is more troublesome to take out the steel bar after bending, and when placing the steel bar on the surface of the device, it needs to be placed according to the position of the groove, and it requires a certain amount of energy to realize the feeding and taking out of the steel bar. Therefore, the utility model provides a steel bar bender capable of automatically feeding materials. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a steel bar bender capable of automatically feeding materials, which solves the problem that when the steel bar bender ensures the bending angle of the steel bar through a groove that restricts the shape of the steel bar, the existence of the groove will limit the quick feeding and taking out of the steel bar, and it requires extra energy to accurately feed and take out the steel bar.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A steel bar bender capable of automatically feeding materials, including a bending machine frame, and a feeding mechanism is arranged inside the bending machine frame to realize the feeding of steel bars. The feeding mechanism includes:

[0007] The feeding component is arranged inside the bending frame to realize the feeding of steel bars, and includes a feeding block fixed inside the bending frame. A grabbing block is slidably arranged inside the feeding block, and a grabbing component is arranged inside the grabbing block to realize the movement of the steel bars. An active block is slidably arranged inside the bending frame, and a sliding component is arranged between the active block and the bending frame to realize sliding restriction. A spacer block is rotatably arranged inside the bending frame, and a disassembly component is arranged between the spacer block and the bending frame to realize position change. An active gear is rotatably arranged on the surfaces of the spacer block and the active block, and an active rack is slidably arranged inside the bending frame.

[0008] The vertical component is arranged inside the bending frame to realize the position restriction of the steel bars, and includes an adjusting block slidable inside the bending frame. A vertical block is slidably arranged inside the adjusting block.

[0009] Preferably, the grabbing component includes an elastic rod rotatably arranged inside the grabbing block. A grabbing spring is fixedly connected between the elastic rod and the grabbing block. A limiting component is arranged between the rear grabbing block and the elastic rod to realize rotational restriction.

[0010] Preferably, the limiting component includes a limiting rod fixed on the surface of the elastic rod. A limiting groove is opened inside the grabbing block, and an arc-shaped block is fixedly connected inside the feeding block.

[0011] Preferably, the sliding component includes a sliding groove opened on the surface of the bending frame. A sliding spring is fixedly connected between the sliding groove and the active block.

[0014] Beneficial effects

[0015] The utility model provides a steel bar bender capable of automatically filling materials. Compared with the prior art, the following beneficial effects are achieved:

[0016] (1) The steel bar bender capable of automatic feeding is provided with a slidable active block inside the bending frame, and a rotatable spacer block is arranged above. The sliding of the active block can drive the spacer block to rotate downward through the active rack. Then, when the steel bar on the surface of the active block is grabbed by the grabbing block, the upward movement of the active block can drive the spacer block to rotate downward. At this time, the steel bar above can fall downward. When the steel bar is moved downward by the active block, the spacer block will return to its original position, and then the whole steel bar will fall down one grid, realizing the automatic feeding of the steel bar and facilitating the convenient feeding during the bending of the steel bar.

[0017] (2) The steel bar bender capable of automatic feeding is provided with an elastic rod that can rotate inside the grabbing block and can automatically return to its original position through the grabbing spring. The elastic rod rotating on the surface of the grabbing block near the active block and the spacer block can be restricted from rotating within a certain position through the fitting of the groove and the block. Then, the elastic rod is restricted from rotating within a certain distance. At this time, when the steel bar is driven to rotate to the bending position, it can be ensured that the steel bar will not press the elastic rod to rotate, and the stable movement of the steel bar to the specified position can be guaranteed, ensuring the stable transportation and feeding of the steel bar.

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides two technical solutions:

[0025] Embodiment 1

A rotatable cylinder is arranged inside the bending frame 1. A steel bar bending structure identical to that in the reference patent is arranged on the surface of the cylinder. A feeding mechanism 2 is arranged inside the bending frame 1 to realize the feeding of steel bars. The feeding mechanism 2 includes:

[0027] A feeding component, which is arranged inside the bending frame 1 to realize the feeding of steel bars, including a feeding block 21 fixed inside the bending frame 1. A grabbing block 22 is slidably arranged inside the feeding block 21. A three-phase asynchronous motor is fixed on the surface of the feeding block 21. A gear and an annular rack are rotatably arranged inside the feeding block 21. The surface of the gear is fixedly connected to one end of the output shaft of the three-phase asynchronous motor through a coupling. The surface of the grabbing block 22 is fixed to the surface of the annular rack. A grabbing component 3 is arranged inside the grabbing block 22 to realize the movement of the steel bar. A driving block 23 is slidably arranged inside the bending frame 1. A sliding component 4 is arranged between the driving block 23 and the bending frame 1 to realize sliding restriction.

A driving gear 25 is rotatably arranged on the surfaces of the spacer block 24 and the driving block 23. A driving rack 26 is slidably arranged inside the bending frame 1. Teeth are fixed inside the bending frame 1. The surface of the driving gear 25 on the surface of the driving block 23 is simultaneously meshed with the surfaces of the teeth and the driving rack 26;

[0028] A vertical component, which is arranged inside the bending frame 1 to realize the position restriction of the steel bar, including an adjusting block 27 slidably arranged inside the bending frame 1. A vertical block 28 is slidably arranged inside the adjusting block 27. The position adjustment between the vertical block 28 and the adjusting block 27 is realized through the disassembly component 5. An elastic rod is rotatably arranged at one end of the vertical block 28. Both the adjusting block 27 and the vertical block 28 are elastic;

[0029] A slidable active block 23 is arranged inside the bending frame 1, and a rotatable spacer block 24 is arranged at the upper position. By the sliding of the active block 23, the spacer block 24 can be driven to rotate downward through the active rack 26. Furthermore, when the steel bar on the surface of the active block 23 is grabbed by the grabbing block 22, the upward movement of the active block 23 can drive the spacer block 24 to rotate downward. At this time, the upper steel bar can fall downward. When the steel bar causes the active block 23 to move downward, the spacer block 24 will return to its position, thereby causing the overall steel bar to fall down one grid, realizing the automatic feeding of the steel bar and facilitating the convenient feeding during steel bar bending.

[0030] Embodiment 2

[0031] The main difference from Embodiment 1 is:

[0032] A steel bar bender capable of automatically filling materials, in which the grabbing assembly 3 includes an elastic rod 31 that rotates inside the grabbing block 22. The elastic rod 31 has a certain elasticity and toughness. A grabbing spring 32 is fixedly connected between the elastic rod 31 and the grabbing block 22. A limiting assembly 33 is arranged between the rear grabbing block 22 and the elastic rod 31 to realize rotational limitation. The limiting assembly 33 includes a limiting rod 331 fixed on the surface of the elastic rod 31. A limiting groove 332 is opened inside the grabbing block 22. An arc-shaped block 333 is fixedly connected inside the feeding block 21. The surface of the arc-shaped block 333 contacts the surface of the limiting rod 331. The sliding assembly 4 includes a sliding groove 41 opened on the surface of the bending frame 1. A sliding spring 42 is fixedly connected between the sliding groove 41 and the active block 23. The surface of the active block 23 is slidably connected to the inner surface of the sliding groove 41. The disassembly assembly 5 includes a disassembly rod 51 that slides inside the spacer block 24. A disassembly spring 52 is fixedly connected between the disassembly rods 51. A disassembly belt 53 is fixedly connected to the surface between the disassembly rods 51. A disassembly groove 54 is opened on the surface of the bending frame 1. A disassembly column 55 is threadedly connected inside the spacer block 24. The disassembly belt 53 is wound around the surface of the disassembly column 55. An elastic rod 31 that can rotate and can automatically return to its position through the grabbing spring 32 is arranged inside the grabbing block 22, and the elastic rod 31 that rotates on the surface of the grabbing block 22 near the active block 23 and the spacer block 24 can be limited in rotation within a certain position through the fitting of the groove and the block, thereby limiting the rotation of the elastic rod 31 within a certain distance. At this time, when driving the steel bar to rotate to the bending position, it can be ensured that the steel bar will not press the elastic rod 31 to rotate, which can ensure the stable movement of the steel bar to the designated position and ensure the stable transportation and feeding of the steel bar.

[0033] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] During operation, first place the steel bar on the surfaces of the active block 23 and the spacer block 24. The steel bar will drive the active block 23 to move downward. At this time, adjust the vertical block 28 to the appropriate position, and then start the motor. The motor will cause the grasping block 22 to slide and rotate. When the grasping block 22 rotates to the position of the steel bar, the elastic rod 31 will rotate under the pressure of the steel bar. At the same time, the lower elastic rod 31 will be restricted from rotating under the action of the limiting component 33. Thus, the steel bar can be stably restricted inside the grasping block 22. After the grasping block 22 slides again, the active block 23 will move upward under the action of the spring. At this time, the active block 23 will cause the spacer block 24 to rotate through the gear and rack. The steel bar above the spacer block 24 moves downward. After the steel bar causes the active block 23 to move downward, the spacer block 24 returns to its position. At the same time, the rotation of the grasping block 22 will move the steel bar inside to the outside and onto the surface of the adjusting block 27. At this time, stop rotating the motor and drive the bending structure to rotate to bend the steel bar. After the steel bar is bent, start the motor again to cause the grasping block 22 to drive the bent steel bar to rotate outward and drop for collection.
