DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Refer to Figure 1 as well as Figure 5 Figure 6 , a stamping metal sheet bending device includes a discharge table 1 and a support frame 2, the support frame 2 is placed vertically to the discharge table 1, and a number of slide grooves are symmetrically opened on both sides of the discharge table 1, and an adjustment mechanism 4 is installed in the slide groove, the adjustment mechanism 4 includes a baffle 41, and there are two baffles 41 and they are symmetrically arranged. The adjustment mechanism 4 also includes a cross plate 42, and the cross plate 42 is slidably installed in the slide groove opened in the array, and the upper surfaces of several cross plates 42 on one side are fixedly connected to the lower surface of the same baffle 41 on the same side, and the lower surface of the cross plate 42 extends through the slide groove, and a gear 44 is provided between the two cross plates 42 in each group of symmetrical positions, and the opposite side walls of the cross plate 42 are installed with racks 43, and the two racks 43 are symmetrical along the axis of the gear 44 and are meshed with the gear 44, and several gears 44 are coaxially fixed with the same rotating shaft 45.

[0027] The rotation of the shaft 45 drives the gear 44 to rotate, and the gear 44 drives the meshed rack 43 to move, and the rack 43 drives the baffle 41 to move. The distance between the two baffles 41 can be adjusted to adapt to the bending operation of metal plates of different widths.

[0028] Reference Figures 5 to 7 The rotating shaft 45 is rotatably mounted on the discharge platform 1 and one end away from the support frame 2 extends through the side wall of the discharge platform 1 and is installed with a locking assembly 46. The locking assembly 46 includes an inner ratchet 461, and the inner ratchet 461 is coaxially fixed with the rotating shaft 45. A pawl 462 is installed on the side wall of the discharge platform 1. The pawl 462 is used in conjunction with the inner ratchet 461. A torsion spring 463 is installed on the rotating shaft 45 of the pawl 462. The pawl 462 cooperates with the inner ratchet 461 to lock the gear 44, and then locks the rack 43 and the baffle 41 to avoid the movement of the baffle 41 during operation, resulting in unsmooth feeding.

[0029] Reference Figures 1 to 4, the power mechanism 3 is installed on the support frame 2, the power mechanism 3 includes a hydraulic press 31, the hydraulic press 31 is fixed to the upper surface of the inner wall of the support frame 2, the hydraulic press 31 is fixed with a load-bearing block 32 at the telescopic end, the load-bearing block 32 is fixed with a connecting plate 36 on the lower surface, the connecting plate 36 is hinged with a pressing plate 37 at the bottom end, the pressing plate 37 is a plate of equal density, the width is asymmetrical on both sides of the hinge line, the width of the side close to the discharge table 1 is wider, the connecting plate 36 An arc-shaped plate 38 is fixed on the side wall facing away from the discharge table 1, and the bottom end of the arc-shaped plate 38 contacts and presses against the pressure plate 37. Two symmetrical guide rods 34 are fixed on the side wall of the load-bearing block 32 facing away from the discharge table 1. The same positioning plate 33 is slidably installed on the two guide rods 34, and a threaded rod 35 is threadedly installed on the side wall of the positioning plate 33. The threaded rod 35 is simultaneously rotatably installed on the side wall of the load-bearing block 32, and a common load-bearing plate 47 is slidably installed on the two baffles 41.

[0030] The operation of the hydraulic press 31 will drive the load-bearing block 32 to move downward, and then drive the connecting plate 36 and the pressure plate 37 hinged to the connecting plate 36 to move downward. The pressure plate 37 will bend the metal plate after contacting the metal plate. Since the stroke of the hydraulic press 31 is adjustable and the pressure plate 37 and the connecting plate 36 are in a hinged relationship, the downward pressure distance of the pressure plate 37 can be adjusted at the same time by controlling the stroke of the hydraulic press 31. Since the horizontal distance between the hinge axis and the side wall of the discharge table 1 remains unchanged, the bending angle can be calculated by the trigonometric function relationship. In general, the bending angle of the metal plate can be controlled by controlling the stroke of the hydraulic press 31 to adapt to metal plates that need to be bent at different angles. Rotating the threaded rod 35 will drive the positioning plate 33 to slide along the guide rod 34, and then adjust to a length suitable for stamping. The arc plate 38 cooperates with the unequal weight setting of the pressure plate 37 on the left and right to keep the pressure plate 37 in a horizontal position when not working, thereby avoiding failure of the stamping operation due to the free shaking of the hinge.

[0031] The working principle of the present invention is as follows: when operation is required, the rotating shaft 45 is rotated according to the width of the metal plate to be processed. The rotation of the rotating shaft 45 can drive the gear 44 to rotate, and then the gear 44 drives the meshing rack 43 to move, and then the rack 43 drives the baffle 41 to move. After the distance between the two baffles 41 is adapted to the width of the metal plate, the pawl 462 cooperates with the inner ratchet 461 to lock the gear 44, and then locks the rack 43 and the baffle 41 to complete the width adjustment. Rotating the threaded rod 35 will drive the positioning plate 33 to slide along the guide rod 34, and then adjust to the length suitable for the stamping of the metal plate, and move the metal plate on the discharge table 1 until one end of the metal plate passes through and extends from under the bearing plate 47. After adjusting the parameters of the hydraulic press 31, start the hydraulic press 31. The operation of the hydraulic press 31 drives the load-bearing block 32 to move downward, and then drives the connecting plate 36 and the pressure plate 37 hinged to the connecting plate 36 to move downward. The pressure plate 37 will bend the metal plate after contacting the metal plate, completing a cycle of operation.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
