[0048] This embodiment provides a steel bar automatic bender. As Figures 1 to 9As shown in the figure, the automatic steel bar bender includes a front first bending main machine 11, a front second bending main machine 12, a material receiving mechanism 30, and a front feeding mechanism 40. Among them, the front first bending main machine 11 is used to bend one end of the steel bar 100, the front second bending main machine 12 is used to bend the other end of the steel bar 100, the material receiving mechanism 30 is used to receive and temporarily store the steel bar 100, and the front feeding mechanism 40 is used to take the steel bar 100 to be bent from the material receiving mechanism 30 and send it to the front first bending main machine 11 and the front second bending main machine 12. In order to improve the processing efficiency, multiple steel bars 100 can be stacked together and bent simultaneously.

[0049] By setting the material receiving mechanism 30, the front feeding mechanism 40, the front first bending main machine 11, and the front second bending main machine 12, the automatic clamping, transfer, and bending of the steel bar 100 are realized, solving the problem of high labor intensity caused by manual auxiliary loading, lifting, and moving and positioning in the prior art. It has a high degree of automation, low labor intensity, is safe and reliable, and has high production efficiency.

[0050] On the basis of the above structure, the automatic steel bar bender further includes a rear first bending main machine 21, a rear second bending main machine 22, and a rear feeding mechanism 50. Among them, the rear first bending main machine 21 is used to bend one end of the steel bar 100 after being processed by the front side bending main machine again, and the rear second bending main machine 22 is used to bend the other end of the steel bar 100 after being processed by the front side bending main machine again.

[0051] The rear feeding mechanism 50 has different functions according to different installation positions. Specifically, when the rear feeding mechanism 50 is set on the front first bending main machine 11 and / or the front second bending main machine 12, the rear feeding mechanism 50 can take the steel bar 100 to be bent from the material receiving mechanism 30 and send it to the front first bending main machine 11 and the front second bending main machine 12; after the steel bar 100 is bent, the rear feeding mechanism 50 takes the steel bar 100 from the front first bending main machine 11 and / or the front second bending main machine 12 and sends it to the rear first bending main machine 21 and the rear second bending main machine 22. That is, when set on the front first bending main machine 11 and / or the front second bending main machine 12, the rear feeding mechanism 50 has the functions of the front feeding mechanism 40.

[0052] When the rear feeding mechanism 50 is set on the rear first bending main machine 21 and / or the rear second bending main machine 22, or the rear feeding mechanism 50 is set between the rear first bending main machine 21 and the rear second bending main machine 22, the rear feeding mechanism 50 is used to take the steel bar 100 processed by the front first bending main machine 11 and the front second bending main machine 12 from the front first bending main machine 11 and the front second bending main machine 12 and send it to the rear first bending main machine 21 and the rear second bending main machine 22, and take out the steel bar 100 bent by the rear first bending main machine 21 and the rear second bending main machine 22 and send it to the next process.

[0053] The specific installation positions of the front first bending main machine 11, the front second bending main machine 12, the rear first bending main machine 21 and the rear second bending main machine 22 are not limited, as long as the connecting and bending processing of the steel bar 100 can be achieved. Preferably, along the conveying direction of the steel bar 100, the front first bending main machine 11 and the front second bending main machine 12 are arranged in the front, the rear first bending main machine 21 and the rear second bending main machine 22 are arranged in the rear, and the rear first bending main machine 21 and the rear second bending main machine 22 are respectively arranged between the front first bending main machine 11 and the front second bending main machine 12. The steel bar 100 is subjected to the first bending processing at the front first bending main machine 11 and the front second bending main machine 12, and the second bending processing at the rear first bending main machine 21 and the rear second bending main machine 22. The processing efficiency is high, and multiple bends can be formed on the steel bar 100.

[0054] In order to improve the applicable range of the automatic steel bar bender, it is preferably to install the front first bending main machine 11, the front second bending main machine 12, the rear first bending main machine 21 and the rear second bending main machine 22 on the track chassis provided with a transmission mechanism. The front first bending main machine 11, the front second bending main machine 12, the rear first bending main machine 21 and the rear second bending main machine 22 can move linearly under the drive of the transmission mechanism, so as to change the distance between the front first bending main machine 11 and the front second bending main machine 12, and the distance between the rear first bending main machine 21 and the rear second bending main machine 22, and can change the distance between the two bending parts on the steel bar 100 according to the use requirements to meet the processing requirements of various specifications of steel bars 100.

[0055] The specific shape of the transmission mechanism is not limited. It can be a combined structure of gears and racks, or a combined structure of sprockets and chains, or a combined structure of conveyor belts and pulleys. Other existing forms of transmission mechanisms are also acceptable.

[0056] The transmission mechanism preferably includes a traveling reduction motor 171, a traveling support wheel 172, a follower gear 173, a driving traveling gear 174 and a guiding bearing 175. The follower gear 173 and the driving traveling gear 174 are connected by a rack (not shown) in the middle.

[0057] The main structures of the front first bending main machine 11, the front second bending main machine 12, the rear first bending main machine 21 and the rear second bending main machine 22 are the same. The front first bending main machine 11 and the front second bending main machine 12 are arranged back to back, and the rear first bending main machine 21 and the rear second bending main machine 22 are arranged back to back.

[0058] Such as Figure 3 and Figure 4As shown, the front first bending main machine 11, the front second bending main machine 12, the rear first bending main machine 21 and / or the rear second bending main machine 22 include a bending speed reduction mechanism (not shown), a bending die 13, a steel bar stop mechanism 14, a bending shaft 15 and a swing arm 16. The bending die 13 is used to fix the steel bar 100 to be bent. The bending shaft 15 is installed on the swing arm 16. After the bending shaft 15 rotates around the bending die 13 by a set angle driven by the swing arm 16, the steel bar 100 can be bent into a set bending angle.

[0059] The outer peripheral radius of the bending die 13 determines the bending radius of the steel bar 100. In order to meet various requirements, a set of bending dies 13 with different outer peripheral radii can be designed for replacement to achieve the change of the bending radius of the steel bar 100.

[0060] As Figures 10 to 12 shown, the material receiving mechanism 30 includes a material receiving fixed seat 31, a material receiving guide shaft 32, a material receiving adjusting plate 33, a spring 34, a material receiving plate 35, a material receiving clamping plate 36, a spring guide shaft 37 and an adjusting shaft 38. The spring 34 is sleeved on the spring guide shaft 37. One end of the spring 34 abuts against the material receiving adjusting plate 33 and the other end abuts against the material receiving clamping plate 36. A material receiving space 39 for accommodating the steel bar 100 is formed between the material receiving plate 35 and the material receiving clamping plate 36. The compressed spring 34 can apply a thrust to the material receiving clamping plate 36, so that the material receiving clamping plate 36 and the material receiving plate 35 jointly clamp the steel bar 100 to prevent the steel bar 100 from accidentally sliding during temporary storage and transportation.

[0061] The adjusting shaft 38 connects the material receiving fixed seat 31 and the material receiving adjusting plate 33. The material receiving adjusting plate 33 is connected to the material receiving guide shaft 32. By adjusting the shaft 38, the distance between the material receiving adjusting plate 33 and the material receiving plate 35 can be changed to meet the usage requirements of steel bars 100 with various diameters. The material receiving guide shaft 32 makes the movement of the material receiving adjusting plate 33 smoother to prevent jamming during its movement due to the skew of the material receiving adjusting plate 33.

[0062] As Figures 13 to 15As shown in the figure, the front feeding mechanism 40 includes a front pneumatic clamping mechanism 60, a front feeding moving guide seat 41, a front feeding lifting frame 42, a three-axis cylinder 43, a feeding fixing frame 44, a moving guide shaft 45, a follower sprocket 46, a chain 47, a driving sprocket 48, and a feeding reduction motor 49. The driving sprocket 48 is installed on the output shaft of the feeding reduction motor 49. The follower sprocket 46 is connected to the driving sprocket 48 through the chain 47. The feeding reduction motor 49 can drive the driving sprocket 48 to rotate. The driving sprocket 48 drives the follower sprocket 46 to rotate synchronously through the chain 47, thereby driving the front feeding moving guide seat 41 to move along the extension direction of the chain 47 (moving guide shaft 45). The front pneumatic clamping mechanism 60 is installed on the front feeding moving guide seat 41 through the front feeding lifting frame 42 and the three-axis cylinder 43. The front feeding moving guide seat 41 can move along the moving guide shaft 45 to realize the horizontal movement of the front pneumatic clamping mechanism 60; the front feeding lifting frame 42 can drive the front pneumatic clamping mechanism 60 to rise and fall to realize the vertical movement of the front pneumatic clamping mechanism 60.

[0063] The structure of the rear feeding mechanism 50 is similar to that of the front feeding mechanism 40. As Figures 16 to 18 shown, the difference is that the rear feeding mechanism 50 further includes a rear pneumatic clamping mechanism 80, and the rear pneumatic clamping mechanism 80 is fixedly connected to the front pneumatic clamping mechanism 60. When the front pneumatic clamping mechanism 60 and the rear pneumatic clamping mechanism 80 simultaneously clamp the steel bar 100, the fixedly connected rear pneumatic clamping mechanism 80 and the front pneumatic clamping mechanism 60 can synchronously move and simultaneously send their respective steel bars 100 to the designated positions, realizing the synchronous feeding of the steel bar 100 by the bending main machines located on the front side (front first bending main machine 11 and front second bending main machine 12) and the bending main machines located on the rear side (rear first bending main machine 21 and rear second bending main machine 22), with low energy consumption and high working efficiency.

[0064] The specific manner in which the front feeding lifting frame 42 drives the front pneumatic clamping mechanism 60 to rise and fall is not limited. Preferably, the rear feeding mechanism 50 further includes a telescopic guide shaft 71, a front feeding lifting cylinder 72, and a front feeding lifting moving guide seat 73. The telescopic guide shaft 71, the front feeding lifting cylinder 72, and the front feeding lifting frame 42 are respectively installed on the front feeding lifting moving guide seat 73. The output end of the front feeding lifting cylinder 72 can drive the front feeding lifting frame 42 to rise and fall.

[0065] On both sides of the front feeding lifting cylinder 72, two telescopic guide shafts 71 are symmetrically arranged. A guide block 74 is arranged on the front feeding lifting moving guide seat 73, and the telescopic guide shaft 71 is inserted into the guide block 74. When the front feeding lifting cylinder 72 drives the front feeding lifting frame 42 to rise and fall, the telescopic guide shaft 71 moves up and down in the guide block 74, thereby ensuring that the front feeding lifting frame 42 can move in a straight line and avoiding skewing during the rising and falling process of the front feeding lifting frame 42.

[0066] Based on the above structure, as Figure 19 and Figure 20 shown, the front pneumatic clamping mechanism 60 preferably includes a front clamping seat 61, a front clamping cylinder 62, a front clamping guide shaft 63, a front moving clamping plate 64 and a front fixed clamping plate 65. The front moving clamping plate 64 is connected to the output shaft of the front clamping cylinder 62. An accommodating space for storing the steel bars 100 is formed between the front moving clamping plate 64 and the front fixed clamping plate 65. The extending length of the output shaft of the front clamping cylinder 62 is adjusted according to the different diameters of the steel bars 100, so as to adjust the width between the front moving clamping plate 64 and the front fixed clamping plate 65, ensuring that the steel bars 100 entering between the front moving clamping plate 64 and the front fixed clamping plate 65 are vertically stacked in a pile, and preventing any two or more steel bars 100 from being arranged in a row horizontally.

[0067] As Figure 21 and Figure 22 shown, the working principle of the rear pneumatic clamping mechanism 80 is similar to that of the front pneumatic clamping mechanism 60. Preferably, the rear pneumatic clamping mechanism 80 includes a rear clamping slide rail 81, a translation cylinder 82, a rear adjusting clamping seat 83, a rear moving clamping plate 84, a rear clamping guide shaft 85 and a rear clamping cylinder 86. The output shaft of the translation cylinder 82 is connected to the rear adjusting clamping seat 83, and the rear moving clamping plate 84 is connected to the output shaft of the rear clamping cylinder 86. An accommodating space for storing the steel bars 100 is formed between the rear adjusting clamping seat 83 and the rear moving clamping plate 84.

[0068] Figures 23 to 37 Shown is the working process of the automatic steel bar bender. In order to reflect the transportation and processing of the steel bars 100 in each stage, the following will use the first group of steel bars 101, the second group of steel bars 102 and the third group of steel bars 103 to distinguish the steel bars 100 respectively.

[0069] Figure 23 Shown is the preparation state. At this time, the first group of steel bars 101 is placed at the edge of the receiving plate 35 of the receiving mechanism 30. This edge is an inclined surface, and the first group of steel bars 101 can slide along the inclined surface into the receiving space 39 of the receiving mechanism 30. Figure 23 is a cross-sectional view at the same position and the same perspective as Figure 5 It can be understood that at this time, the first group of steel bars 101 is horizontally across the edge of the receiving plate 35 of all the receiving mechanisms 30 between the front first bending main machine 11 and the front second bending main machine 12.

[0070] Figure 24 and Figure 25As shown, all the steel bars of the first group of steel bars 101 enter the material receiving space 39 of the material receiving mechanism 30, and all the steel bars of the first group of steel bars 101 are arranged in a stack. The compressed spring 34 applies thrust to the material receiving clamping plate 36, and the material receiving clamping plate 36 and the material receiving plate 35 clamp the first group of steel bars 101 together.

[0071] Figure 26 As shown, the front pneumatic clamping mechanism 60 on the front feeding mechanism 40 and the front pneumatic clamping mechanism 60 of the rear feeding mechanism 50 disposed on the front second bending main machine 12 are simultaneously lifted upward, the accommodation space between the front movable clamping plate 64 and the front fixed clamping plate 65 holds the first group of steel bars 101, and the front pneumatic clamping mechanism 60 clamps the first group of steel bars 101. Figure 27 As shown, the lifting force of the front pneumatic clamping mechanism 60 exceeds the clamping force that the spring 34 can apply to the first group of steel bars 101, so the front pneumatic clamping mechanism 60 on the front second bending main machine 12 lifts the first group of steel bars 101 upward, and the first group of steel bars 101 are separated from the material receiving space 39 of the material receiving mechanism 30.

[0072] Figure 28 and Figure 29 It is shown that the front pneumatic clamping mechanism 60 moves horizontally toward the bending mold 13 of the front second bending main machine 12 until the first group of steel bars 101 are transported to the top of the bending mold 13, and the front pneumatic clamping mechanism 60 stops moving.

[0073] Figure 30 The front pneumatic clamping mechanism 60 is shown falling, placing the first set of steel bars 101 into the bending mold 13. Figure 31 As shown, the front pneumatic clamping mechanism 60 releases the first group of steel bars 101 and continues to fall, and the first group of steel bars 101 are completely separated from the front pneumatic clamping mechanism 60.

[0074] Figure 32 The front pneumatic clamping mechanism 60 is shown to be reset, waiting to receive the second group of steel bars 102; the swing arm 16 drives the bending shaft 15 to swing, and bends the first group of steel bars 101. In order to show the bending process more clearly, Figure 32 The figure shows one half (right half) of the entire automatic steel bar bending machine, and at this time the other half (left half) of the automatic steel bar bending machine is also synchronously bending the left end of the first group of steel bars 101.

[0075] Figure 33As shown, after the first group of steel bars 101 are bent and processed, the front pneumatic clamping mechanism 60 on the front feeding mechanism 40 clamps and lifts the second group of steel bars 102. The front pneumatic clamping mechanism 60 of the rear feeding mechanism 50 provided on the front second bending main machine 12 also clamps and lifts the second group of steel bars 102 at the same time. The rear pneumatic clamping mechanism 80 fixed together with the front pneumatic clamping mechanism 60 on the rear feeding mechanism 50 clamps and lifts the first group of steel bars 101.

[0076] Figure 34 As shown, the front pneumatic clamping mechanism 60 and the rear pneumatic clamping mechanism 80 move horizontally synchronously. The front pneumatic clamping mechanism 60 transports the second group of steel bars 102 directly above the bending die 13 of the front second bending main machine 12, and the rear pneumatic clamping mechanism 80 transports the first group of steel bars 101 directly above the bending die 13 of the rear second bending main machine 22.

[0077] The front pneumatic clamping mechanism 60 descends, and the second group of steel bars 102 are caught in the bending die 13 of the front second bending main machine 12. The front pneumatic clamping mechanism 60 releases the second group of steel bars 102 and continues to descend until the second group of steel bars 102 are separated from the front pneumatic clamping mechanism 60. The rear pneumatic clamping mechanism 80 descends synchronously. The first group of steel bars 101 are caught in the bending die 13 of the rear second bending main machine 22. The rear pneumatic clamping mechanism 80 releases the first group of steel bars 101 and continues to descend until the first group of steel bars 101 are separated from the rear pneumatic clamping mechanism 80.

[0078] Figure 35 As shown, the front pneumatic clamping mechanism 60 on the front feeding mechanism 40 resets, and the front pneumatic clamping mechanism 60 and the rear pneumatic clamping mechanism 80 on the rear feeding mechanism 50 reset together. The bending die 13 of the front second bending main machine 12 bends the second group of steel bars 102, and the bending die 13 of the rear second bending main machine 22 bends the first group of steel bars 101 again.

[0079] Figure 36 As shown, the front pneumatic clamping mechanism 60 on the front feeding mechanism 40, and the front pneumatic clamping mechanism 60 of the rear feeding mechanism 50 provided on the front second bending main machine 12 lift and clamp the third group of steel bars 103 synchronously. The rear pneumatic clamping mechanism 80 on the rear feeding mechanism 50 lifts and clamps the second group of steel bars 102 synchronously; the front pneumatic clamping mechanism 60 of the rear feeding mechanism 50 on the rear second bending main machine 22 lifts and clamps the second group of steel bars 102, and the rear pneumatic clamping mechanism 80 of the rear feeding mechanism 50 on the rear second bending main machine 22 lifts and clamps the first group of steel bars 101 synchronously. All the front pneumatic clamping mechanisms 60 and the rear pneumatic clamping mechanisms 80 continue to lift, so that the third group of steel bars 103 are separated from the receiving space 39 of the receiving mechanism 30, the second group of steel bars 102 are separated from the bending die 13 of the front second bending main machine 12, and the first group of steel bars 101 are separated from the bending die 13 of the rear second bending main machine 22.

[0080] Figure 37 Shown are the front pneumatic clamping mechanism 60 on the front feeding mechanism 40, the front pneumatic clamping mechanism 60 and the rear pneumatic clamping mechanism 80 of the rear feeding mechanism 50 on the front second bending main machine 12, and the front pneumatic clamping mechanism 60 and the rear pneumatic clamping mechanism 80 of the rear feeding mechanism 50 on the rear second bending main machine 22 moving horizontally synchronously until the third group of steel bars 103 are fed into the bending die 13 of the front second bending main machine 12, the second group of steel bars 102 are fed into the bending die 13 of the rear second bending main machine 22 and the first group of steel bars 101 are sent to the next process.
