[0040] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1-5 , the present invention provides the following technical solutions: A sheet metal bending device for industrial processing, including a machine platform 1 and a stamping and forming mechanism 3, and further including a transmission mechanism 2 and a stock feeding mechanism 4.

[0042] Furthermore, by Figures 1-3As shown, in this embodiment, the transmission mechanism 2 includes a frame 21, two main rollers 22 symmetrically distributed and rotatably mounted on the frame 21, two main transmission belts 23 symmetrically distributed and a driving motor 24, the two main transmission belts 23 are tensioned by the two main rollers 22, the driving motor 24 is fixed on the frame 21 to drive the main rollers 22 to rotate, the material-digging mechanism 4 includes a rodless cylinder No. 1 fixed on the frame 21, a fixed plate No. 1 fixed on the slider of the rodless cylinder 41, a material-digging block 43 located on one side of the fixed plate No. 1, and a horizontal cylinder No. 44, the horizontal cylinder No. 44 is fixed on the fixed plate No. 42, and the piston rod of the horizontal cylinder No. 44 passes through the fixed plate No. 42 and is fixedly connected to the material-digging block 43. After adopting the above scheme, when in use, start the driving motor 24. The driving motor 24 drives the main roller 22 to rotate, so that the two main transmission belts 23 rotate, and the sheet metal parts to be processed are placed on the two main transmission belts 23 for transmission. When the sheet metal parts are transmitted to the processing position, the driving motor 24 pauses, and then the stamping and forming mechanism 3 is actuated to bend and form the sheet metal parts. After the forming is completed, the driving motor 24 is restarted, and the No. 1 horizontal cylinder 44 is actuated. The No. 1 horizontal cylinder 44 pushes the material shifting block 43 to move, so that the material shifting block 43 moves to one side of the sheet metal part. Then the No. 1 rodless cylinder 41 is actuated, and the material shifting block 43 is used to shift the sheet metal parts for unloading. The utility model transmits the sheet metal parts through the transmission mechanism 2, and uses the stamping and forming mechanism 3 to stamp and bend the sheet metal parts. There is no need to manually place and unload materials, and the processing efficiency is greatly improved, which meets the needs of mass production.

[0043] It should be noted that in actual production, the rodless cylinder 41 can be started in advance to move the material shifting block 43 to the rear of the processing position, and then the horizontal cylinder 44 can be started to drive the material shifting block 43 to move. At this time, the material shifting block 43 can be used to position the sheet metal from the rear. When the sheet metal is blocked by the material shifting block 43 during the transmission process, it is in the processing position at this time. After the sheet metal is bent, the material shifting block 43 moves to the front side of the sheet metal.

[0044] Preferably, by Figure 1 As shown, in this embodiment, there are two groups of symmetrically distributed material shifting mechanisms 4. After adopting the above design, the two groups of material shifting mechanisms 4 can shift the sheet metal parts from both sides at the same time, which can ensure the stability of the sheet metal parts and ensure that the sheet metal parts move in a straight line.

[0045] Preferably, by Figure 1 and Figure 3As shown, in this embodiment, the transmission mechanism 2 further includes: a secondary roller 25 and a secondary transmission belt 26. The secondary roller 25 is rotatably mounted on the frame 21. The two secondary transmission belts 26 are symmetrically distributed, and the secondary transmission belt 26 is tensioned by the secondary roller 25 and the main roller 22 at the end. After adopting the above design, during use, since the length of the sheet metal part becomes shorter after being bent, the present utility model has redesigned the transmission mechanism 2. By introducing the secondary roller 25 and the secondary transmission belt 26, when the two main transmission belts 23 rotate, the secondary transmission belt 26 rotates in the same direction, and the secondary transmission belt 26 is located inside the two main transmission belts 23. During later blanking, the blanking mechanism 4 will push the sheet metal part onto the secondary transmission belt 26 for output, ensuring the reliability of blanking.

[0046] Optionally, by Figure 1 and Figure 4 As shown, in this embodiment, the stamping and forming mechanism 3 includes: a lower hydraulic cylinder 31, a lower die set 32, side plates 33, a top plate 34, an upper die base 35, and an upper hydraulic cylinder 36. The lower hydraulic cylinder 31 is fixed on the machine table 1. The lower die set 32 is fixed to the top end of the piston rod of the lower hydraulic cylinder 31, and a bending groove 321 is provided on the lower die set 32. The two side plates 33 are symmetrically fixed to the top surface of the machine table 1. The top plate 34 is fixed to the top ends of the side plates 33. The upper die base 35 is located directly above the lower die set 32, and a bending block 351 is fixed to the bottom surface of the upper die base 35. The upper hydraulic cylinder 36 is fixed on the top plate 34, and the piston rod of the upper hydraulic cylinder 36 passes through the top plate 34 and is fixedly connected to the upper die base 35. After adopting the above solution, when the sheet metal part reaches the processing position, the lower hydraulic cylinder 31 is activated. The lower hydraulic cylinder 31 pushes the lower die set 32 upward to lift the sheet metal part by the lower die set 32. Then the upper hydraulic cylinder 36 is activated, and the upper hydraulic cylinder 36 pushes the upper die base 35 downward. The bending of the sheet metal part is achieved by the cooperation of the bending block 351 and the bending groove 321. After the forming is completed, the lower hydraulic cylinder 31 is activated to move the lower die set 32 downward so that the top surface of the lower die set 32 is flush with or slightly lower than the bottom surface of the blanking block 43.

[0047] Preferably, by Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment, the distance between the two secondary transmission belts 26 is equal to the width of the bending groove 321. In fact, the distance between the two secondary transmission belts 26 not greater than the width of the bending groove 321 is acceptable, so that the two secondary transmission belts 26 can support the bent sheet metal part from both ends.

[0048] It should be noted that as can be seen from the drawings, the bending device of the present utility model is used to bend the sheet metal part into a "V" shape. Therefore, two symmetrically distributed secondary transmission belts 26 are designed. After the sheet metal part is bent, the middle part of the sheet metal part can pass through the inner space between the two secondary transmission belts 26.

[0049] Preferably, as shown by Figure 1 and Figure 5 In this embodiment, a blanking mechanism 5 is further included, and the blanking mechanism 5 includes: a second fixed plate 52, a blanking block 53, and a second horizontal cylinder 54. The second fixed plate 52 is movably connected to the frame 21. The blanking block 53 is located on one side of the second fixed plate 52. The second horizontal cylinder 54 is fixed on the second fixed plate 52, and the piston rod of the second horizontal cylinder 54 penetrates through the second fixed plate 52 and is fixedly connected to the blanking block 53. After adopting the above solution, during use, when the previous sheet metal part reaches the processing position, at this time, the second horizontal cylinder 54 operates, and the second horizontal cylinder 54 drives the blanking block 53 to move, and the subsequent sheet metal parts are blocked by the blanking block 53, so as to prevent the subsequent sheet metal parts from affecting the bending of the previous sheet metal part.

[0050] Preferably, as shown by Figure 1 and Figure 5 In this embodiment, the blanking mechanism 5 further includes: a second rodless cylinder 51. The second rodless cylinder 51 is fixed on the frame 21, and the second fixed plate 52 is fixed on the slider of the second rodless cylinder 51. After adopting the above solution, starting the second rodless cylinder 51 can change the initial position of the blanking block 53, which is applicable to sheet metal parts of different lengths.

[0051] Preferably, as shown by Figure 1 and Figure 5 In this embodiment, two groups of the blanking mechanisms 5 are symmetrically distributed. After adopting the above solution, the subsequent sheet metal parts are blocked from both sides by the two groups of blanking mechanisms 5 at the same time, and the stability is higher.

[0052] It should be noted that the drive motor 24, the lower hydraulic cylinder 31, the upper hydraulic cylinder 36, the first rodless cylinder 41, the first horizontal cylinder 44, the second rodless cylinder 51, and the second horizontal cylinder 54 are all commercially available conventional devices with built-in power switches.

When the sheet metal part is blocked by the material pushing block 43 during transmission, it is at the processing position at this time;

[0056] After the sheet metal part reaches the processing position, the lower hydraulic cylinder 31 is started, the lower hydraulic cylinder 31 pushes the lower die set 32 to rise, jack up the sheet metal part through the lower die set 32. Then the upper hydraulic cylinder 36 is started, the upper hydraulic cylinder 36 pushes the upper die base 35 to move downward, and the bending block 351 cooperates with the bending groove 321 to realize the bending and forming of the sheet metal part. After the forming is completed, the lower hydraulic cylinder 31 is started and the lower die set 32 is moved downward, so that the top surface of the lower die set 32 is flush with the bottom surface of the material pushing block 43 or slightly lower than the bottom surface of the material pushing block 43 is acceptable;

[0057] Then cooperate with the first rodless cylinder 41 and the first horizontal cylinder 44 to move the material pushing block 43 to the front side of the sheet metal part;

[0058] Finally, the driving motor 24 is restarted, the first horizontal cylinder 44 acts, the first horizontal cylinder 44 pushes the material pushing block 43 to move, so that the material pushing block 43 moves to one side of the sheet metal part. Then the first rodless cylinder 41 acts, and the sheet metal part is pushed onto the secondary transmission belt 26 for output by the material pushing block 43;

[0059] The present utility model transports the sheet metal part through the transmission mechanism 2, and uses the stamping and forming mechanism 3 to stamp and bend the sheet metal part. There is no need for manual loading and unloading, and the processing efficiency is greatly improved, meeting the mass production requirements.
