Technical Field

[0001] The present invention belongs to the field of metal plate manufacturing equipment, and particularly relates to a roll forming machine for metal plate flow channels. Background Art

[0002] Currently, most metal plates are processed using stamping forming equipment. Its disadvantages are that when forming large-area flow channels, precise stamping dies and presses providing large pressure are required. The forming system is complex, and problems such as springback, cracking, and wrinkling are likely to occur during the forming process, resulting in poor economic benefits. Summary of the Invention

[0003] The purpose of the present invention is to provide a roll forming machine for metal plate flow channels, which can effectively overcome the disadvantages of the existing technology.

[0004] The present invention is implemented as follows. Its feature is that inside a trough-shaped workbench, a feeding roller and front pressing upper and lower rollers driven by a first motor are installed at its front end, and an encoder is installed at one end of the feeding roller; a roll forming device is installed in the middle of the workbench, including first, second, third, and fourth upper forming rollers and a lower pressing roller; rear pressing upper and lower rollers are installed at the rear end of the workbench; the first, second, third, and fourth upper forming rollers are sequentially installed on the same circumference of the left and right turntables at both ends of the middle shaft; a middle large gear and a gear ring are installed outside the left turntable at the left end of the middle shaft, the middle large gear meshes with the first, second, third, and fourth small gears respectively, the first, second, third, and fourth small gears are sequentially installed on the left end journals of the first, second, third, and fourth upper forming rollers respectively, and mesh with the gear ring respectively; the end of the middle shaft is connected to a second motor; a layer of polyurethane rubber with a hardness value of HS75A is sleeved on the roller surface of the lower pressing roller; on the roller surfaces of the first, second, third, and fourth upper forming rollers, the same circumferential protrusions are made, and the height of the circumferential protrusions is equal to the depth of the grooves on the plate surface of the plate.

[0005] The advantages and positive effects of the present invention are as follows:

[0006] The present invention overcomes the problems of springback and uneven thickness in the existing technology; the four upper forming rollers are concentrated on the same turntable, with a simple structure, saving space, being conducive to continuous production, and improving the forming efficiency; a layer of polyurethane rubber is sleeved on the roller surface of the lower pressing roller, suppressing the defect of warping of the sheet.
