[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0028] See Figures 1-7 A thin plate natural forming device includes a base 1, an active unit 2 and a pressing unit 3. The base 1 serves as a bottom support and can be a plate with a flat upper surface.

[0029] Several slide rails 11 are arranged on the upper surface of the base 1 extending in the left and right direction. For example, two parallel slide rails 11 are set on the base 1, and the movable unit 2 is slidably set on the slide rails 11.

[0030] For movable unit 2, it includes a first movable member 21 and a second movable member 22, that is, both the first movable member 21 and the second movable member 22 are slidably disposed on the slide rail 11, and a first elastic unit (not shown in the figure) is provided on the first movable member 21 and the second movable member 22. The two ends of the first elastic unit abut against or are fixed to the lower end of the inner end wall of the first movable member 21 and the lower end of the inner end wall of the second movable member 22, respectively. The first elastic unit is used to separate the first movable member 21 and the second movable member 22 when no external force is applied to them, so as to... Figure 2 In the direction shown, influenced by the first elastic unit, the first movable member 21 moves to the left and the second movable member 22 moves to the right.

[0031] In one implementation, the first elastic unit is a spring.

[0032] In this embodiment, the outer ends of the first movable member 21 and the second movable member 22 are respectively provided with a plurality of first inclined blocks 23. As one implementation, the front and rear parts of the outer ends of the first movable member 21 are respectively provided with corresponding first inclined blocks 23; the front and rear parts of the outer ends of the second movable member 22 are also respectively provided with corresponding first inclined blocks 23.

[0033] The inclined surface of the first inclined block 23 is located on its outer side, so as... Figure 2 As shown in the directions, the inclined surface of the first inclined block 23 of the first movable member 21 gradually tilts to the left from top to bottom; the inclined surface of the first inclined block 23 of the second movable member 22 gradually tilts to the right from top to bottom.

[0034] In the embodiment, corresponding columns 12 are arranged at the four corners of the base 1, and a corresponding second inclined block 31 is arranged to slide on each column 12. As an embodiment, a slide rail can be arranged on the inner side wall of the column 12, and the second inclined block 31 is arranged to slide on the slide rail.

[0035] The second inclined block 31 is a part of the pressing unit 3, and is arranged to cooperate with the first inclined block 23. The number and arrangement position of the second inclined block 31 correspond to those of the first inclined block 23. The inclined surface of the second inclined block 31 corresponds to that of the first inclined block 23, so that when the second inclined block 31 moves downward, the first movable part 21 and the second movable part 22 can be driven to move horizontally to the center of the base 1, and are folded together.

[0036] The pressing unit 3 further includes a main unit 32 and a forming head 33 arranged on the main unit 32. Four second inclined blocks 31 are arranged on the bottom surface of the main unit 32, and are arranged at the four corners of the main unit 32, respectively, and correspond to the columns 12 and the first inclined blocks 23.

[0037] The forming head 33 is arranged at the relatively middle position of the bottom surface of the main unit 32. Correspondingly, the first movable part 21 and the second movable part 22 have corresponding forming openings, respectively. Specifically, the first movable part 21 includes a first forming opening 211 at the upper part of the inner end, and the second movable part 22 includes a second forming opening 221 at the upper part of the inner end. When the first movable part 21 and the second movable part 22 are folded together, the first forming opening 211 and the second forming opening 221 are also folded together, and the shape formed by the folding corresponds to the shape of the forming head 33. Meanwhile, after the folding, the forming head 33 also descends into the overall forming opening formed by the folding, as shown in Figure 1 , Figure 2

[0038] In the embodiment, at least two groups of elastic units are arranged on the bottom surface of the main unit 32. Each group of elastic units is connected with a corresponding pressing block 34. One of the two pressing blocks 34 corresponds to the first movable part 21, and the other corresponds to the second movable part 22.

[0039] ​When the main unit 32 is driven by the driving member (which can be a stamping head or a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc. according to the prior art) to move downward, the lower pressing block 34 moves downward along with it until it contacts the sheet placed above the first movable element 21 and the second movable element 22 and exerts pressure on it. At this time, the first movable element 21 cooperates with one of the lower pressing blocks 34, and the second movable element 22 cooperates with the other lower pressing block 34 to clamp the two ends of the sheet, respectively. With the convergence of the first movable element 21 and the second movable element 22, the extrusion force is formed on the middle part of the sheet that needs to be shaped, and cooperates with the first shaping port 211, the second shaping port 221, and the shaping head 33 to make the middle part of the sheet deviate to the natural shape required for shaping to ensure the shaping strength, such as Figure 7 shown, is a shape of the sheet after shaping.

[0040] Depending on the force exertion mode of the elastic unit group and the lower pressing block 34, the ends of the sheet can be pressed without affecting the normal transverse movement of the first movable element 21 and the second movable element 22 below the sheet.

[0041] The shaped shape can be specifically selected according to actual needs, and the shapes of the shaping head 33, the first shaping port 211, and the second shaping port 221 can be changed accordingly.

[0042] In the embodiment, each group of elastic units includes a plurality of second elastic units 35, and the second elastic units 35 can be springs. As one of the implementation manners, the elastic unit group includes at least six second elastic units 35, which are arranged on the bottom surface of the main unit 32 in two groups from front to back, as shown in Figure 6 .

[0043] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some of the technical features. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
