[0024] The sheet metal forming device provided by the utility model adjusts the distance between the driven roller and the active roller by means of an adjusting member, places the sheet metal to be processed between the active roller and the driven roller, adjusts the adjusting member so that the driven roller abuts against the upper surface of the sheet metal, starts a driving mechanism, drives the active roller to rotate, and forms ribs or folded edges on the sheet metal moving forward.

[0025] The sheet metal forming device is described below in conjunction with specific embodiments to further understand the utility model concept of the sheet metal forming device.

[0026] In one embodiment, if Figure 1-3 As shown, a sheet metal forming device includes a frame 100, a driving mechanism 200 arranged on one side of the frame 100, a driving shaft 300 connected to the driving mechanism 200, and a driven shaft matched with the driving shaft 300. A driving roller 310 is arranged at one end of the driving shaft 300 away from the driving mechanism 200, and a driven roller 410 matched with the driving roller 310 is arranged at one end of the driven shaft 400 away from the driving mechanism 200. The driving roller 310 is detachably connected to one end of the driving shaft 300, and the driven roller 410 is detachably connected to one end of the driven shaft 400. Specifically, the connection can be made by screwing or clamping. By means of this detachable connection, the applicability of the forming device is improved. When rib pressing is required, the rib pressing wheel can be replaced, and when folding is required, the folding wheel can be replaced. The two sides of the driven shaft 400 are slidably matched with the frame 100. An adjusting member 170 is provided on the crossbeam 110 of the frame 100 near the driven shaft 400. The distance between the driven roller 410 and the active roller 310 is adjusted by the adjusting member 170. Specifically, the adjusting member 170 includes an adjusting screw 171 and a T-block 172 fixedly connected to the head of the adjusting screw 141. The adjusting screw 171 passes through a reserved screw hole on the crossbeam 110. Slide rails 111 are respectively provided on both sides of the adjusting screw 171 on the lower end surface of the crossbeam 110. The two sides of the T-block 172 are slidably matched with the slide rails 111. A through hole is provided in the central part of the T-block 172. A first bearing 430 is provided in the through hole. The two sides of the driven shaft 400 are sleeved in the first bearing 430, so that the driven shaft 400 and the T-block 172 can rotate. When adjusting the distance between the active roller 310 and the driven roller 410, it is only necessary to rotate the adjusting screw 171 to drive the driven shaft 400 to move upward or downward. Specifically, when processing sheet metal, first rotate the adjusting screw 171 to drive the driven shaft 400 to move upward, and place the sheet metal to be processed between the active roller 310 and the driven roller 410. After the placement is completed, rotate the adjusting screw 171 to drive the driven shaft 400 to move downward. When the driven roller 410 abuts against the upper end surface of the sheet metal, stop rotating the adjusting screw 171 and perform subsequent processing.

[0027] Preferably, if Figure 3As shown, a positioning nut is also provided on the adjusting screw 141. When the positioning nut abuts against the upper end surface of the crossbeam, it indicates that the height of the driven shaft 400 is adjusted to the right position, and at this time, the adjusting screw 171 stops rotating.

[0028] In another embodiment, if Figure 2-3 As shown, the driven shaft 400 is provided with a first auxiliary wheel 420 on one side close to the driven roller 410, and the crossbeam 100 is provided with a second auxiliary wheel 130 that can be raised and lowered on one end away from the driving mechanism 200. The first auxiliary wheel 420 and the second auxiliary wheel 130 can both contact the upper surface of the sheet metal during sheet metal processing. In this embodiment, the first auxiliary wheel 420 and the second auxiliary wheel 130 suppress deformation of the sheet metal caused by the stress generated by rolling on the sheet metal during processing. Specifically, a side of the crossbeam 110 close to the driven roller 410 is provided with an extension rod 112, and the lower end of the extension rod is provided with a mounting seat 180 for mounting the second auxiliary wheel 130, and the mounting seat 180 can be lifted and lowered and mounted on the lower side of the extension rod 112. Specifically, the upper end surface of the mounting seat 180 is mounted on the crossbeam 110 by two bolts 181, wherein the head of the bolt 181 passes through the extension rod 112 and is fixed by a positioning nut, and a positioning nut is also provided on the portion of the bolt 181 located on the lower side of the extension rod 112, and the second auxiliary wheel 130 is mounted on the lower side of the mounting seat 180. After the processed sheet metal is placed in place, the positioning nut on the bolt 181 is loosened, the bolt is rotated, and the height of the mounting seat is adjusted. When the second auxiliary wheel 130 abuts against the upper end surface of the sheet metal, the two positioning nuts are fixed so that each positioning nut abuts against the upper and lower end surfaces of the extension rod 112. At this time, the second auxiliary wheel is adjusted into place.

[0029] In another embodiment, if Figure 1-2 As shown, a support platform 120 is provided in the frame 100, and the support platform 120 is located at the lower side of the driving shaft 300. Both sides of the driving shaft 300 are rotatably connected to the support platform 120. Specifically, both sides of the driving shaft 300 near the end are respectively provided with seat bearings, and the lower end faces of the seat bearings are fixed to the support platform 120. One end of the driving shaft 300 near the driving mechanism 200 is connected to the driving mechanism 200 through a coupling.

[0030] In another embodiment, if Figure 1-2As shown, a sheet metal limiting assembly 140 is slidably arranged on the support platform 120, and one side of the sheet metal is supported by the limiting assembly 140. Specifically, a slider 141 is arranged on one end of the limiting assembly 140 close to the support platform 120, and a guide rail 121 cooperating with the slider is arranged on the support platform 120; the limiting assembly 140 also includes a first support column 142 and a support plate 144 arranged on the upper end of the first support column 142, the first support column 142 is arranged on the upper end surface of the slider 141, and the support plate 144 is flush with the uppermost end of the active roller 310. When placing the sheet metal to be processed, the limiting assembly 140 is slid according to the width of the sheet metal, so that one side of the sheet metal away from the active roller 310 is placed on the upper end surface of the support plate 144. Preferably, a limiting column 145 is further provided at one end of the support plate 144 away from the active roller 310. Two limiting columns 145 may be provided, which are respectively located at the two corners of the support plate 144. In order to facilitate the sheet metal to move forward during processing, the limiting column 145 can rotate. Specifically, the limiting column 145 may include a fixed column and a roller. The fixed column is fixedly provided on the upper end surface of the support plate 144, and the roller is sleeved on the outer periphery of the fixed column to ensure that the sheet metal will not have a rigid contact with the limiting column 145 when it moves forward. In this embodiment, by providing a limiting component, the limiting component is slidably provided on the support platform 120. According to the width of the sheet metal to be processed, the position of the limiting component and the component can be adjusted, so that one side of the sheet metal away from the processing end is located on the support plate of the limiting component, and a limiting column is provided at one end of the support plate, so as to ensure that the sheet metal will not deflect when it moves forward, and effectively ensure the accuracy and stability of sheet metal processing.

[0031] In another embodiment, the active roller 310 is a rolling concave wheel, and the driven roller 410 is a rolling cam, and ribs are formed on the sheet metal part through the cooperation of the rolling concave wheel and the rolling cam.

[0032] In another embodiment, the active roller 310 is a flanging cam, and the driven roller 410 is a flanging concave wheel, and a folded edge is formed on the sheet metal part through the cooperation between the flanging cam and the flanging concave wheel.

[0033] In another embodiment, the bottom end of the frame 100 is provided with universal wheels 150 and a liftable suction cup 160. When the molding device needs to be moved, the suction cup 160 is raised. After the device is moved into place, the suction cup 160 is lowered so that the suction cup 160 is adsorbed on the ground, thereby fixing the molding device for later stable processing.

[0034] The utility model provides a sheet metal forming device, taking the sheet metal rib pressing process as an example, comprising the following steps: a first step, firstly adjusting the driven shaft 400 upwards, that is, by rotating the adjusting screw 171, the driven shaft 400 is moved away from the driving shaft 300 by a certain distance; a second step, installing a rolling concave wheel on the driving shaft, and installing a rolling cam on the driven roller shaft; a third step, placing the sheet metal between the rolling concave wheel and the rolling cam, wherein the side of the sheet metal away from the rolling cam is placed on the support plate 144, and the side is abutted against the limiting column, and the height of the mounting seat 180 is adjusted so that the second auxiliary wheel 130 abuts against the surface of the sheet metal; a fourth step, starting the driving mechanism 200 to drive the driving shaft 300 to rotate, manually or using other special equipment to push the sheet metal slowly forward, and with the cooperation of the rolling concave wheel and the rolling cam, ribs are formed on the sheet metal until the rib pressing processing on the sheet metal is completed.
