Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0029] like Figure 1-4 As shown, the utility model provides a technical solution: a feeding device for a bending machine, comprising a bending machine 1, a frame 2 is arranged on one side of the bending machine 1, a slide groove 3 is provided at the top of the frame 2, a clamping assembly 4 is arranged inside the slide groove 3, a carrying box 5 is arranged on one side of the slide groove 3, an opening 7 is opened inside the carrying box 5, and a feeding mechanism 6 is arranged on the frame 2 at the carrying box 5;

[0030] The feeding mechanism 6 includes a driving motor 601, which is fixedly installed on one side of the frame 2. The output end of the driving motor 601 passes through the frame 2 and is fixedly connected to a transmission rod 602. A first gear 603 is fixedly installed on the end of the transmission rod 602 away from the driving motor 601. A gear belt 604 is meshedly connected to the outer side of the first gear 603. A side of the gear belt 604 away from the first gear 603 is meshedly connected to multiple groups of second gears 605. A transmission roller 606 is fixedly installed on the side of the first gear 603 and the second gear 605 away from the driving motor 601, and the other end of the transmission roller 606 is rotatably installed on the frame 2 through a bearing.

[0031] Specifically, one side of the transmission roller 606 is arranged on the surface of the frame 2 , and the second gear 605 is rotatably mounted on the frame 2 , and one side of the transmission roller 606 and the second gear 605 are both supported by the frame 2 .

[0032] Specifically, the carrying box 5 is provided with a plurality of groups of transversely arranged carrying frames 8 at the opening 7, a carrying rod 9 is fixedly installed below the carrying frame 8, a positioning rod 10 is elastically connected below the carrying rod 9, a spring 11 is sleeved on the outer side of the positioning rod 10, and a roller 12 is fixedly installed at the bottom end of the positioning rod 10. The elastically arranged positioning rod 10 and the roller 12 at the bottom end of the positioning rod 10 can achieve a downward pressing effect on metal steel plates of different thicknesses during the feeding process, thereby increasing the friction between the metal steel plates and the feeding mechanism 6.

[0033] Specifically, a mounting plate 13 is fixedly installed on one side of the carrying box 5 close to the bending machine 1, and a rotating rod 14 is installed on the middle thread of the mounting plate 13. A tension spring 15 is sleeved on one end of the rotating rod 14 located on the bottom end surface of the mounting plate 13, and a limiting plate 16 is fixedly installed on the end of the rotating rod 14. By rotating the rotating rod 14, the rotating rod 14 drives the limiting plate 16 to move up and down through the threaded connection between the rotating rod 14 and the mounting plate 13, so as to be suitable for metal steel plates of different thicknesses, and the limiting plate 16 has a limiting and fixing effect on the metal steel plate at the bending machine 1.

[0034] Specifically, the limiting plate 16 is a trapezoidal structure, and a rubber pad is provided on the bottom end surface of the limiting plate 16 , which can increase the friction between the limiting plate 16 and the metal steel plate and reduce the wear of the metal steel plate when the limiting plate 16 is pressed down.

[0035] Specifically, the clamping assembly 4 includes a hydraulic cylinder 401, which is fixedly installed on both sides of the slide groove 3. The telescopic ends of the hydraulic cylinder 401 are fixedly installed with sliding clamping plates 402. A plurality of connecting bearings are laterally arranged on the inner side of the sliding clamping plate 402. The clamping assembly 4 can limit the metal steel plate in the feeding through the two groups of sliding clamping plates 402, and reduce the friction between the metal steel plate and the sliding clamping plate 402 through the multiple groups of connecting bearings arranged laterally.

[0036] Specifically, a control panel 17 is fixedly installed on one side of the bending machine 1, and the control panel 17 is electrically connected to the feeding mechanism 6 and the clamping assembly 4. The control panel 17 can operate the feeding mechanism 6 and the clamping assembly 4 more conveniently.

[0037] The working process of the utility model is as follows: first, the metal steel plate to be fed is placed above the transmission roller 606, then the hydraulic cylinder 401 of the clamping assembly 4 is opened to push the sliding clamping plate 402, so that the sliding clamping plate 402 fixes the position of the metal steel plate, and when the metal steel plate is located above the transmission roller 606, its roller 12 will press the metal steel plate down through the elastically arranged positioning rod 10, so that the connection between the metal steel plate and the transmission roller 606 can be more closely connected, and the friction between the two can be increased, so that the feeding effect of the metal steel plate can be better, and then the driving motor 601 of the feeding mechanism 6 is turned on, and the driving motor 601 is driven by the driving motor 601. The motor 601 drives the transmission rod 602 and the first gear 603 to rotate, and the first gear 603 drives the gear belt 604 to rotate, and the gear belt 604 drives the second gear 605 to rotate. The rotation of the first gear 603 and the second gear 605 can drive the transmission roller 606 on the other side to rotate, thereby feeding the metal steel plate. When one side of the metal steel plate moves to the bending machine 1, the rotating rod 14 is manually rotated to make the rotating rod 14 press down the limit plate 16, so that the bottom end surface of the limit plate 16 supports the metal steel plate. This not only avoids the movement of the metal steel plate during the bending process, but also avoids the metal steel plate from warping during bending.
