DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] The embodiment of the present application provides a sheet metal bending device with automatic feeding, such as Figure 1-Figure 5 As shown, it includes a feeding roller 1, a baffle 2, a pushing mechanism, a support platform 4, a second pressing mechanism 403, etc.

[0027] Specifically, the feed rollers 1 are a pair, which are arranged between a pair of vertical plates 101 and are arranged to rotate in opposite directions; the baffles 2 are a pair, which are arranged on one side of the feed roller 1, and a support block 201 is vertically provided at the bottom of the inner side of the baffle 2, for supporting the sheet metal 3 placed in the pair of baffles 2, and the height of the top of the support block 201 matches the height of the top of the feed roller 1 below; the pushing mechanism is provided on one side of the feed roller 1, for pushing the sheet metal 3 at the bottom placed in the baffle 2 toward the feed roller 1; the support platform 4 is provided on the other side of the feed roller 1, and a first pressing mechanism 401 is provided above the support platform 4 for fixing the sheet metal 3, and an arc-shaped protrusion 402 is provided on the side of the support platform 4 away from the feed roller 1; the telescopic end of the second pressing mechanism 403 is connected to a strip pressure block 4031, and the length direction of the strip pressure block 4031 is the same as the length direction of the feed roller 1, and the horizontal distance between the strip pressure block 4031 and the arc-shaped protrusion 402 matches the thickness of the sheet metal 3 to be bent.

[0028] During actual use, multiple plates are stacked on top of the support block 201, and the pushing mechanism is controlled to push the bottom sheet metal 3 toward the feed roller 1. When the sheet metal 3 enters the gap between a pair of feed rollers 1, it will be driven by the feed roller 1 to move toward the support platform 4. After the sheet metal 3 is separated from the feed roller 1, the first pressing mechanism 401 is controlled to press down to press the plate tightly and fix it, and then the telescopic end of the second pressing mechanism 403 is controlled to drive the strip pressure block 4031 to move downward to bend the plate.

[0029] Preferably, see Figure 2-Figure 4The feeding mechanism includes a cam 5 and a connecting rod 6. The cam 5 is connected to a rotating shaft 501. The axial direction of the rotating shaft 501 is the same as the axial direction of the feeding roller 1. The rotating shaft 501 is spaced below the baffle 2. The rotating shaft 501 is driven by a driving mechanism. One end of the connecting rod 6 is hinged to a cross bar 601. The cross bar 601 is vertically fixed to the vertical plate 101. A disc 602 is provided on one side of the connecting rod 6. The circumference of the disc 602 abuts against the circumference of the cam 5. The side of the connecting rod 6 facing the feeding roller 1 is connected to one end of a first spring 603. The other end of the first spring 603 is connected to the vertical plate 101 through a fixing rod 604. A strip-shaped through slot 605 is provided on the top of the connecting rod 6. A connecting shaft 606 is disposed within the strip-shaped through-slot 605. Connecting plates 7 are connected to both ends of the connecting shaft 606. The end of the connecting plate 7 facing the feed roller 1 is slidably connected to a first slider 701. The first slider 701 is fixed to the fixed rod 604. The length of the first slider 701 aligns with the feeding direction of the feed roller 1. The other end of the connecting plate 7 is connected to a push block 702. The height of the top of the push block 702 matches the height of the top of the bottommost sheet metal 3 placed in the baffle 2. When the disc 602 abuts the protrusion 502 of the cam 5, the push block 702 maintains a predetermined distance from the sheet metal 3 placed in the baffle 2, and the first spring 603 is in a stretched state. During the rotation of the disc, when the disc 602 abuts the recessed portion 503 of the cam 5, the first spring 603 is in a natural state, and the push block 702 pushes the sheet metal 3 placed in the bottommost portion of the baffle 2 between the feed rollers 1. That is, as the cam 5 rotates, in conjunction with the extension and contraction of the spring, the connecting rod 6 can be controlled to rotate, thereby driving the connecting plate 7 and the push block 702 to slide back and forth along the length direction of the first slider 701, pushing the bottom sheet metal 3 between a pair of feed rollers 1, so that the sheet metal 3 is fed into the support platform 4 in turn for bending.

[0030] Preferably, see Figure 1 The driving mechanism includes a first transmission wheel 8, a second transmission wheel 801, and a transmission belt 802. The first transmission wheel 8 is connected to the rotating shaft 501, and the feed roller 1 is driven by the driving motor. The second transmission wheel 801 is connected to the output shaft of the driving motor. The transmission belt 802 is sleeved outside the first transmission wheel 8 and the second transmission wheel 801, and the diameter of the first transmission wheel 8 is larger than the diameter of the second transmission wheel 801. When the first transmission wheel 8 rotates one circle, the feed roller 1 rotates a preset number of circles. Specifically, it can be set that when the feed roller 1 rotates a preset number of circles, the sheet metal 3 entering between the pair of feed rollers 1 can be completely transported to the support platform 4 for subsequent bending. Through this structure, the feed roller 1 and the cam 5 can be driven to rotate simultaneously by only one power source.

[0031] Preferably, see Figure 1 、 Figure 2The vertical plate 101 is provided with a vertical slot 1011, within which a pair of second sliders 9 are slidably connected. The top of the lower second slider 9 is provided with a connecting post 901, while the bottom of the upper second slider 9 is provided with a sliding slot, in which the connecting post 901 is slidably connected. The top of the upper second slider 9 is connected to the vertical plate 101 via a second spring 902. One end of a pair of feed rollers 1 is respectively rotatably connected to a pair of second sliders 9, and the other end of a pair of feed rollers 1 is respectively rotatably connected to another pair of second sliders 9. When the upper second slider 9 is fully lowered, the second spring 902 is in its natural state. That is, when the sheet metal 3 enters between the pair of feed rollers 1, if the thickness of the sheet metal 3 is greater than the initial spacing between the pair of feed rollers 1, the sheet metal 3 can push the upper feed roller 1 upward, preventing the sheet metal 3 from being stuck between the pair of feed rollers 1 during transportation.

[0032] For details, see Figure 5 , limit plates 202 are vertically provided at both ends of the baffle 2. When the sheet metal 3 is placed on the support block 201, the top height of the bottom sheet metal 3 matches the bottom height of the limit plate 202, which is used to prevent the upper sheet metal 3 from sliding, resulting in the push block 702 being unable to reach the outside of the sheet metal 3 to push the sheet metal 3.

[0033] The above are only some of the embodiments listed in this application and are not intended to limit this application.
