[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0028] The sheet metal flanging and bending machine of this utility model is described below with reference to the accompanying drawings.

[0029] Figure 1 This is a structural schematic diagram of a sheet metal flanging and bending machine according to an embodiment of the present utility model.

[0030] like Figure 1 As shown in the figure, the sheet metal flanging and bending machine of this utility model employs a multi-pass progressive flanging process at the edge of the sheet metal part. First, a small-angle pre-flanging is performed, and then the flanging angle is gradually increased. This allows the material to gradually adapt during each deformation pass, reducing the springback caused by a large-angle flanging at once. The process may include:

[0031] frame;

[0032] The bending angle hydraulic device 1 includes a bending hydraulic pump, a bending seat and a bending punch. The hydraulic pump is mounted on the surface of the frame. The output end of the bending hydraulic pump is connected to the bending punch. The bending angle hydraulic device 1 is used to bend the edge of the sheet metal part.

[0033] The bending and attaching device 2 includes a roller seat 201, an attaching roller 202, a guide rail 203, a mounting frame 204, an attaching seat 205, and an attaching pump 206. The attaching roller 202 is rotatably connected to the inner wall of the roller seat 201. The attaching seat 205 is located at the outlet of the bending seat. The side of the sheet metal part after bending is in contact with the surface of the attaching seat 205. The surface of the attaching roller 202 is in contact with the attaching seat 205. The roller seat 201 is slidably connected to the slide of the guide rail 203. The attaching roller 202 is rotatably connected to the inner wall of the roller seat 201. The output end of the attaching pump 206 is connected to one side of the roller seat 201. The track of the guide rail 203 and the pump body of the attaching pump 206 are both fixed inside the mounting frame 204.

[0034] like Figures 1-3 As shown, specifically, the edge of the sheet metal part is first impacted and bent by the bending angle hydraulic device 1. The bending edge hydraulic pump drives the bending punch to impact the edge of the sheet metal part. After the edge of the sheet metal part is bent, the bent edge is fed to the bending edge attachment device 2. The attachment roller 202 gradually applies force to the edge position, so that the "L"-shaped bending edge attachment becomes an "I" shape. In order to reinforce the edge of the sheet metal part, the "I"-shaped edge of the sheet metal part returns to the bending seat position. The bending angle hydraulic device 1 bends the "I"-shaped edge, and the bending edge attachment device 2 bends it again. The springback rate of the sheet metal part edge is reduced after being bent more than twice.

[0035] Sheet metal part conveying device 3 is set at the outlet of the bending seat; the sheet metal part conveying device 3 is used to feed the sheet metal part into the bending seat and the attached seat 205.

[0036] Specifically, the sheet metal part advancing device 3 is used in the above-mentioned technical operation to send the edge of the sheet metal part into the bending seat of the bending angle hydraulic device 1, and then send the edge into the attachment seat 205 position of the bending edge attachment device 2, and then send the "I"-shaped edge to the attachment seat 205 position, and repeat the bending process multiple times.

[0037] Sheet metal part clamp 4 is set on sheet metal part advancing device 3 and is used to fix sheet metal parts.

[0038] In one embodiment of this utility model, such as Figure 1 As shown, it should be noted that, specifically, the attachment seat 205 is slidably connected to the frame and fixed with screws, and the mounting bracket 204 is slidably connected to the frame and fixed with screws. The position of the attachment seat 205 can be adjusted according to the thickness of the sheet metal part. The vertical length of the attachment seat 205 and the bending seat is the thickness of the sheet metal part. In order to keep the attachment roller 202 in contact with the attachment seat 205, it should be adjusted appropriately. If the rotating folding shape is hollow, it can be adjusted so that there is a slight distance between the attachment roller 202 and the attachment seat 205.

[0039] Specifically, the sheet metal part advancing device 3 includes an advancing track 301 and a servo cylinder. The sheet metal part fixture 4 is slidably connected to the track of the advancing track 301. The servo cylinder is connected to the frame, and the output end of the servo cylinder is connected to one side of the sheet metal part fixture 4. The sheet metal advancing device can be driven by a servo cylinder. Common servo cylinders have short strokes and occupy space in the cylinder body position, but servo cylinders are precise and have a fast response.

[0040] like Figure 4 As shown, specifically, the sheet metal part advancing device 3 includes an advancing track 301 and a screw-type linear module. The sheet metal part clamp 4 is slidably connected to the track of the advancing track 301. The frame of the screw-type linear module is connected to the machine frame. The slider of the screw-type linear module is connected to the sheet metal part clamp 4. The stroke length of the screw-type linear module can be customized at will, which is convenient for the use of large sheet metal parts and the position is accurate.

[0041] Specifically, the input end of the lead screw linear module is a motor. The motor controls the lead screw linear module, and the position of the linear mold slider can control the flange length of the sheet metal part.

[0042] Specifically, the input end of the lead screw linear module is a turntable, which allows manual control of the movement position at the edge of the sheet metal part for processing.

[0043] Specifically, the sheet metal fixture 4 includes a clamping base 401 and a clamping cylinder 402. There are two sets of clamping base 401 and clamping cylinder 402. The output end of the clamping cylinder 402 is connected to an L-shaped fixed edge 403. The clamping cylinder 402 is connected to the clamping base 401. It also includes a lead screw bearing seat 404. The central axis of the lead screw bearing seat 404 is connected to a bidirectional lead screw 405. Both threads of the bidirectional lead screw 405 are threaded to threaded sliders. The input end of the lead screw bearing set is connected to a motor. Both sets of threaded sliders are slidably connected to the inner wall of the lead screw bearing seat 404. The two sets of clamping cylinders 402 are respectively connected to the surfaces of the two sets of threaded sliders.

[0044] Plate-shaped sheet metal parts can be clamped and fixed by two sets of clamping cylinders 402. Frame-shaped sheet metal parts can return to their original position through the output end of the clamping cylinders 402. The two sets of clamping cylinders 402 form two clamping surfaces, which can clamp the frame-shaped sheet metal parts. The positions of the two sets of clamping cylinders 402 can be adjusted. A motor drives a bidirectional lead screw 405, and two sets of threaded sliders threaded to the bidirectional lead screw 405 move in opposite directions to clamp the sheet metal parts according to their dimensions.

[0045] Specifically, the edge of the sheet metal part is impacted and bent by the bending angle hydraulic device 1. The bending edge hydraulic pump drives the bending punch to impact the edge of the sheet metal part. After the edge of the sheet metal part is completed and bent, the bent edge is fed to the bending edge attachment device 2. The attachment roller 202 gradually applies force to the edge position, so that the "L"-shaped bending edge attachment becomes an "I" shape. In order to reinforce the edge of the sheet metal part, the "I"-shaped edge of the sheet metal part returns to the bending seat position. The bending angle hydraulic device 1 bends the "I"-shaped edge, and the bending edge attachment device 2 bends it again.

[0046] In summary, the sheet metal flanging and bending machine of this utility model gradually increases the flanging angle when flanging thin plates. This allows the material to gradually adapt during each deformation pass, reducing the springback caused by a large-angle flanging at one time. The springback rate is reduced at the edges of sheet metal parts that have been bent more than twice.
