Description
Technical Field
[0001] This utility model relates to the field of steel bar bending technology, and in particular to an automatic feeding mechanism for a steel bar bending device. Background Technology
[0002] Rebar bending is a common rebar processing technique in building construction. It involves bending rebar into shape to meet the shape and size requirements of components (such as beams, columns, slabs, stirrups, etc.) in the design drawings. A prior art patent application (CN202220205389.3) describes a rebar bending device comprising: a base plate, a first guide wheel, a slide groove, a lead screw, a moving plate, a slider, a second guide wheel, a hydraulic cylinder, and a bending block. The device places the rebar in the moving groove of the bending block, positioning it between the first groove of the first guide wheel and the second groove of the second guide wheel. Then, the lead screw is rotated, causing the slider to move, which in turn moves the second guide wheel towards the first guide wheel, thereby simultaneously embedding the rebar into both the first and second grooves. The process involves clamping the reinforcing bars to fix both ends and improve their stability. Then, the hydraulic cylinder is activated, moving the bending block to bend the reinforcing bars. After bending, the screw is rotated to disengage the second guide wheel from the reinforcing bar, allowing it to be removed. However, in practice, the reinforcing bars must be manually fixed between the guide wheels before bending, and then removed before starting the next set of bars. This results in poor continuity and high manual labor intensity. Therefore, we propose an automatic feeding mechanism for a reinforcing bar bending device. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0015] Reference Figure 1-7 An automatic feeding mechanism for a steel bar bending device includes a base 5, a guide structure 1 for limiting the steel bar body 4, a cutting structure 2 for cutting the steel bar body 4, a hydraulic cylinder 6 and a bending block 7 for bending the steel bar body 4, and a feeding structure 3 for feeding the steel bar body 4. Specifically, the guide structure 1 pushes the steel bar body 4 to feed it, the hydraulic cylinder 6 drives the bending block 7 to bend the steel bar body 4, the cutting structure 2 cuts the steel bar body 4, and the unloading structure 3 pushes the steel bar body 4 out for unloading. The bending block 7 is located at the rear end of the hydraulic cylinder 6. When the hydraulic cylinder 6 extends, it can drive the bending block 7 to move. The entire equipment is powered by an external power source and controlled by external equipment.
[0016] In a preferred embodiment, the guide structure 1 includes a motor 106, a second gear 105 disposed above the motor 106, a second guide wheel 102 disposed above the second gear 105, a rotating shaft 104 disposed behind the motor 106, a first gear 103 sleeved on the surface of the rotating shaft 104 and meshing with the second gear 105, and a first guide wheel 101 disposed above the first gear 103. Specifically, the drive motor 106 causes the second gear 105 to rotate the second guide wheel 102, which in turn drives the first gear 103 and the first guide wheel 101 to rotate. This causes the first guide wheel 101 and the second guide wheel 102 to rotate clockwise and counterclockwise, respectively, thus pushing the steel bar body 4 to one side. The motor 106 is a TZ20S02, and its output end is connected to the second gear 105, which drives the second gear 105 to rotate, thereby driving the second guide wheel 102 to rotate. Since the first gear 103 meshes with the second gear 105, and the rotating shaft 104 is rotatably installed inside the base plate 507, it can drive the first guide wheel 101 to rotate.
[0017] In a preferred embodiment, the cutting structure 2 includes a U-shaped plate 201, a first electric push rod 202 disposed below the U-shaped plate 201, a cutting blade 203 that can be extended by the first electric push rod 202, and sliders 205 disposed on the front and rear surfaces of the U-shaped plate 201, the sliders 205 being in two sets, and a handle 204 disposed on the sliders 205 and a gravity block 206 located below the handle 204. Specifically, the first electric push rod 202 pushes the cutting blade 203 downward to cut the steel bar body 4. The first electric push rod 202 extends and drives the cutting blade 203 downward, so that the cutting blade 203 cuts the steel bar body 4. Since the gravity block 206 has a large mass, it is always embedded in the limiting groove 501 when there is no external force, thereby limiting the U-shaped plate 201.
[0018] In a preferred embodiment, the base 5 includes a base plate 507 and a slide groove 502 on one side. The slide groove 502 is in two sets, including multiple sets of limiting grooves 501 located inside the slide groove 502 on the upper surface of the base plate 507, a horizontal plate 504 on the upper surface of the base plate 507, two sets of threaded rods 503 on the horizontal plate 504, a first limiting plate 505 on the front surface of the threaded rods 503, and two sets of second limiting plates 506 located on the upper surface of the base plate 507 and in front of the first limiting plate 505. Specifically, by rotating the threaded rod 503, the position of the first limiting plate 505 is adjusted. The first limiting plate 505 and the second limiting plate 506 clamp and fix the steel bar body 4. The threaded rod 503 is located on the horizontal plate 504 and is sleeved inside the threaded hole. When the threaded rod 503 rotates, it can make the first limiting plate 505 move, thereby working together with the second limiting plate 506 to squeeze and limit the steel bar body 4.
[0019] In a preferred embodiment, the motor 106 and the rotating shaft 104 are both located inside the base plate 507 on one side. The slider 205 is embedded in the slide groove 502. The gravity block 206 is embedded in the limiting groove 501. The steel bar body 4 is located between the first guide wheel 101 and the second guide wheel 102, inside the U-shaped plate 201, and between the first limiting plate 505 and the second limiting plate 506. The hydraulic cylinder 6 is located on the upper surface of the base plate 507 at the front. Specifically, the bending block 7 is moved by the hydraulic cylinder 6 to bend the steel bar body 4. The motor 106 is fixed inside the base plate 507, and the rotating shaft 104 is rotatably connected to the inside of the base plate 507 and can rotate inside the base plate 507. The slider 205 can rotate inside the slide groove 502 to adjust the position of the U-shaped plate 201. The U-shaped plate 201 is fixed by embedding the gravity block 206 into the limiting groove 501.
[0020] In a preferred embodiment, the feeding structure 3 includes a second electric push rod 303 capable of driving the connecting rod 302 to move up and down, and also includes two sets of push plates 301 located at the top of the connecting rod 302; Specifically, by driving the second electric push rod 303, the second electric push rod 303 is extended, thereby driving the connecting rod 302 to rise, and then pushing the two sets of push plates 301 to rise.
[0021] In a preferred embodiment, the second electric push rod 303 is located inside the base plate 507 on the side away from the guide structure 1, and the push plate 301 is located below the steel bar body 4; Specifically, by driving the second electric push rod 303, the connecting rod 302 pushes the push plate 301 upward, thereby pushing the steel bar body 4 upward, so that the steel bar body 4 is away from the first limiting plate 505 and the second limiting plate 506, making it easier to unload.
[0022] It should be noted that the main body 4 of the reinforcing bar is placed between the first guide wheel 101 and the second guide wheel 102. The drive motor 106 pushes the main body 4 of the reinforcing bar through the first gear 103 and the second gear 105. The position of the U-shaped plate 201 is adjusted as needed so that the gravity block 206 is embedded in the limiting groove 501 for fixation. When the main body 4 of the reinforcing bar is pushed to the appropriate position, the hydraulic cylinder 6 is activated, and the bending block 7 bends the main body 4 of the reinforcing bar. After bending, the first electric push rod 202 is driven, and the cutting blade 203 cuts the main body 4 of the reinforcing bar. The second electric push rod 303 is activated, and the connecting rod 302 pushes the push plate 301 to rise, thereby pushing out the main body 4 of the reinforcing bar.
[0023] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
