[0001] This invention relates to the field of steel bar processing equipment, specifically to a steel bar bending and packaging device and its usage method. Background Technology

[0002] Reinforcing steel bars are metallic materials used to reinforce concrete structures, typically appearing in long strips. Made of steel, they possess high tensile strength and excellent mechanical properties, making them a commonly used material in construction engineering. When used, reinforcing steel bars often require bending operations to facilitate subsequent use.

[0003] Currently, rebar bending machines and rebar bundling machines exist in China, but most are still in a semi-manual, semi-automatic stage. They primarily rely on close-range human assistance to bend and bundle the rebar. However, existing rebar bending and bundling machines have excessively long cycles and require close worker involvement. Due to the uncertainties in rebar bending and bundling operations, manual operation carries certain risks and cannot quickly bundle beam rebar after processing, severely impacting production efficiency and resulting in high labor costs.

Detailed Implementation

[0029] See Figures 1-7 As shown, the technical solution adopted in this specific embodiment is as follows: it includes a support base 1, characterized in that: a climbing system 2, a bending system 3, a packing mechanism 4 and a height adjustment mechanism 6 are installed on the support base 1, and a CNC worktable 7 is provided on the support base 1. The conveying climbing system 2 is set on one side of the bending system 3, and the packing mechanism 4 is provided on the other side of the bending system 3. The packing mechanism 4 is connected to the wire feeding mechanism 5, and one end of the wire feeding mechanism 5 is installed on the height adjustment mechanism 6.

[0030] As a more specific description of the present invention: the conveying climbing system 2 includes a supporting mounting base plate 28, and a conveying platform 22 is provided on one side above the supporting mounting base plate 28. A conveying motor 21 and a conveying belt 23 are installed on the top of the conveying platform 22, and the conveying motor 21 and the conveying belt 23 are mechanically connected. One side of the conveying belt 23 is clearance-fitted with the climbing moving plate 24. The side of the climbing moving plate 24 is slidably connected to the lifting plate guide rail 25 through a limiting connecting block 26. A lifting reciprocating motor 27 is installed at the bottom of the climbing moving plate 24. When it is necessary to perform steel bar bending and packaging operations, the workers can first place the steel bars on the conveyor belt 23. The conveyor motor 21 drives the conveyor belt 23 to move, and the conveyor belt 23 transports the steel bars to the bottom of the climbing moving plate 24. At this time, the lifting reciprocating motor 27 will drive the climbing moving plate 24 to reciprocate, so that the climbing moving plate 24 will reciprocate to lift the steel bars step by step to the top of the climbing moving plate 24, so that the steel bars can enter the bending system 3 for bending operations. When the climbing moving plate 24 lifts the steel bars, the lifting plate guide rail 25 and the limiting connecting block 26 can ensure that the climbing moving plate 24 maintains a stable direction and trajectory.

[0031] As a more specific description of the present invention: the bending system 3 includes a fixed base plate 32, on which an adjusting guide rail 31 and a side rack 33 are mounted. Two bending support platforms 34 are slidably connected to the adjusting guide rail 31. An adjusting motor 37 is mounted at the front end of the bending support platform 34, and the adjusting motor 37 meshes with the side rack 33 through a rack connecting tooth 36. A leveling telescopic motor 38 is mounted above one side of the bending support platform 34, and a side balance bar 35 is provided above the other side of the bending support platform 34. Both the side balance bar 35 and the leveling telescopic motor 38 are connected to their leveling baffles 39. A bending shaft platform 310 is mounted on the top of the bending support platform 34. A steel bar bending module 312 and a bending shaft 311 are provided in the middle of the bending shaft platform 310. A steel bar clamping clamp 313 is provided between the two bending support platforms 34, and multiple top support rods 314 are provided on each of the two bending support platforms 34. When the reinforcing bar enters the bending system 3 from the conveying and climbing system 2, it will fall onto the top support rod 314 to prevent it from falling directly onto the bending system 3 and causing unnecessary damage. Then, the top support rod 314 will slowly descend, allowing the reinforcing bar to fall between the reinforcing bar clamp 313 and the reinforcing bar bending module 312. At this time, the leveling telescopic motor 38 will drive the leveling baffle 39 to move inward, using the leveling baffle 39 to level the reinforcing bar so that it is in the middle position. After leveling, the central reinforcing bar clamp 313 will clamp the column reinforcing bar to ensure that the reinforcing bar clamp 313 will not slip unnecessarily. Then, the adjusting motor 37 will drive the bending support platform 34 to move outward to the preset position through the rack connecting gear 36 based on the side rack 33. Subsequently, the bending shaft 311 will be used to bend the reinforcing bar. After the reinforcing bar is bent, it will be lifted by the top support rod 314 and conveyed to the packaging mechanism 4.

[0032] As a more specific description of the present invention: the packaging mechanism 4 includes an annular rack 42, a tensioning rack 43 is movably connected to the front opening of the annular rack 42, and a hydraulic device 44 is connected to the middle of the tensioning rack 43. A wire clamping mechanism 45 is engaged on the annular rack 42, a clamping and fixing device 41 is installed below the annular rack 42, and a transport belt 46 is provided on both the left and right sides of the annular rack 42. When the bent steel bars enter the packaging mechanism 4 from the bending system 3 through the top support rod 314, they will enter the inner cavity of the outer winding rail 42 from the front opening of the outer winding rail 42. When multiple steel bars enter and form a steel bar pile, the clamping and fixing device 41 will start to clamp the steel bar pile to ensure that the steel bar pile is more stable and neat. The opening and closing rack 43 will close, so that the opening and closing rack 43 and the ring rack 42 form a complete winding rail. At this time, the packaging line will be sent out from the wire feeding mechanism 5 and clamped by the line clamping mechanism 45. After the line clamping mechanism 45 clamps the line, it will circle around the ring rack 42, so that the line can circle the steel bar pile. The line clamping mechanism 45 will then insert the line into the wire feeding mechanism 5. The wire feeding mechanism 5 will then tie the packaging line. The packaged steel bar pile will be transported to the outside through the conveyor belt 46.

[0033] As a more specific description of the present invention: the wire feeding mechanism 5 includes an extension support plate 53, one end of which is fixedly connected to the height adjustment mechanism 6. The extension support plate 53 is provided with a wire drum power mechanism 52, and the wire drum power mechanism 52 is mechanically connected to the winding drum 51. The winding drum 51 is provided with a packing wire. The side of the winding drum 51 is provided with a transmission roller group 56 and a wire inlet end 57. The extension support plate 53 is provided with a winding motor 54, and the output end of the winding motor 54 is provided with a clamping end 55. During the packaging operation, the worker should first thread the packaging line into the inlet end 57 and have the transmission roller assembly 56 press the packaging line in place. Then, when packaging is required, the spool power mechanism 52 will drive the winding spool 51 to rotate, so that the packaging line enters the clamping end 55 from the transmission roller assembly 56 and is finally clamped by the line clamping mechanism 45. After the line clamping mechanism 45 is completed, the end of the line will return to the clamping end 55. At this time, the clamping end 55 will hold the packaging line, and the excess packaging line will be recycled by the winding spool 51 for the next packaging. When the packaging line is recycled and the steel bar pile can be packaged, the cutting blade on the wire feeding mechanism 5 will cut the packaging line and drive the clamping end 55 to rotate quickly through the winding motor 54, thereby completing the knotting operation of the packaging line.

[0034] As a more specific description of the present invention: the height adjustment mechanism 6 includes a lifting base plate 63 for support and fixation, a lifting component 62 with height adjustment lifting capability, and a support top plate 61 for connecting and supporting the wire feeding mechanism 5.

[0035] As a more specific description of the present invention: the clamping and fixing device 41 consists of a side push rod 41-1, a clamping and fixing claw 41-2, and a central fixing plate 41-3. Two clamping and fixing claws 41-2 are provided, and their central portions are connected to each other via the central fixing plate 41-3. The side push rod 41-1 is located on the outer side below each of the two clamping and fixing claws 41-2. When it is necessary to clamp the steel bar stack, the side push rods 41-1 on both sides will drive the clamping and fixing claws 41-2, causing them to clamp the steel bar stack based on the central fixing plate 41-3, ensuring the neatness and stability of the steel bar stack.

[0036] As a more specific description of the present invention: the wire clamping mechanism 45 includes an H-shaped plate 45-4, which is sleeved on an annular rack 42, and a circumferential locking tooth 45-3 is provided between the annular rack 42 and the H-shaped plate 45-4. The circumferential locking tooth 45-3 is provided on the output end of the circumferential motor 45-2. A motor support plate 45-1 is fixedly connected to one side of the H-shaped plate 45-4. A first motion mechanism 45-6 is provided below the H-shaped plate 45-4. A second motion mechanism 45-7 is connected to the outer end of the first motion mechanism 45-6, and a wire clamp 45-5 is provided on the outer side of the second motion mechanism 45-7. During the packaging operation, the packaging line will be discharged from the wire feeding mechanism 5 and clamped by the wire clamp 45-5. Then, the circling motor 45-2 will drive the circling tooth 45-3, so that the wire clamping mechanism 45 will perform a circling operation on the steel bar pile based on the ring rack 42. After one circling, the packaging line will be sent back to the clamping end 55 by the wire clamp 45-5. When the wire clamp 45-5 clamps the packaging line and sends it back to the clamping end 55, its first motion mechanism 45-6 and second motion mechanism 45-7 can drive the wire clamp 45-5 to make multi-angle adjustments, so that the wire clamp 45-5 can better clamp the packaging line and perform the wire feeding operation.

[0037] As a more specific description of the present invention: the center of the support base 1 is recessed inward to form a central groove 101. The central groove 101 facilitates the installation of the annular rack 42 and the movement of the wire clamping mechanism 45.
