[0038] The following is combined with Figures 1 to 6 This application is described in further detail.

[0039] A plate bending device, comprising:

[0040] Two sliders 1 are arranged opposite to each other;

[0041] The rotating block 2 has two lugs and corners; each lug is hinged to a corresponding slider 1 through a pin;

[0042] The support block 3 is slidably connected between the two sliders 1, and one of its corner portions is opposite to the angular portion, and a bending space is formed between the corner portion and the angular portion; the axis of the pin passes through the bending space, and specifically can be colinear with the tip of the angular portion.

[0043] The above-mentioned plate bending device can be used in specific applications as follows:

[0044] Adjust the relative position between the support block 3 and the two sliders 1 to change the size of the bending space between the corresponding corners and the corners on the rotating block 2 to adapt to the thickness of the plate 8;

[0045] The plate 8 to be bent is extended from the bending space so that the portion to be bent is stuck in the bending space and contacts the corresponding corners and edges;

[0046] Press the rotating block 2 downward on the part of the plate 8 that needs to be bent, so that the plate 8 is bent from the part that needs to be bent, and the downward bending of the plate 8 is completed. When the corresponding corner part is 90°, the part of the plate 8 that needs to be bent can be accurately bent downward to 90°, such as Figure 2 shown.

[0047] As for the sheet bending device disclosed in the above-mentioned embodiment, technicians in the field can understand that when bending the sheet 8, the part of the sheet 8 that needs to be bent is clamped in the bending space, in contact with the corresponding corners and edges, and located on the rotation axis of the rotating block 2, which can effectively constrain the sheet 8 and accurately control the bending angle of the part of the sheet 8 that needs to be bent according to the angle design of the corresponding corners. In addition, the size of the bending space can be adjusted to adapt to the thickness of different sheets 8, and it has high versatility.

[0048] In some optional embodiments, in the above-mentioned sheet bending device, the support block 3 is connected to the two sliding blocks 1 via a slide rail, and can be fixed by bolts after sliding into place.

[0049] In some optional embodiments, the above-mentioned plate bending device further includes:

[0050] The pressing block 4 can be connected to the supporting block 3 in a detachable manner, specifically by bolts, and its edge portion extends to the bending space, and can press the plate 8 during the bending process of the plate 8, impose constraints on the plate 8, and prevent the plate 8 from deforming at the non-bending portion, such as Figure 1 As shown, its specific shape can be designed in various ways according to actual needs.

[0051] In some optional embodiments, in the above-mentioned sheet bending device, the edge of the pressing block 4 extending to the bending space is an inclined surface, and the angle between the pressing block 4 and the supporting block 3 is less than 90°.

[0052] After the plate 8 is bent at the portion to be bent by the plate bending device, it can be further bent inwards, as shown below:

[0053] Place the plate 8 with the bent portion facing upward on the support block 3, with the bent portion located in the bending space and against the corresponding corners and edges;

[0054] The pressing block 4 is pressed on the plate 8;

[0055] The rotating block 2 is pulled inward and pressed on the bent part of the plate 8, so that the plate 8 is bent from the bent part, and the inward bending of the plate 8 is completed. When the angle between the inclined surface and the support block 3 is 30°, the part of the plate 8 that needs to be bent can be accurately bent inward to 30°, such as Figure 3 As shown, in practical applications, multiple different angles between the inclined surface and the support block 3 can be designed according to actual needs;

[0056] After removing the pressing block 4, the folded portion of the plate 8 can be further bent inward by turning the rotating block 2 inward, and the portion to be bent can be flattened inward, such as Figure 4As shown, since it is performed on the basis of inward bending of the bending part of the plate 8, the bending part forms an acute angle with the main part, and the bending can be controlled to occur only at the bending part, and deformation of other parts will not occur.

[0057] In some optional embodiments, the above-mentioned plate bending device further includes:

[0058] The distance block 5 is connected to the support block 3 in a detachable manner and has a distance protrusion thereon; the distance protrusion is opposite to the bending space and the size between the distance protrusion and the bending space is determined. The distance protrusion can be used to calibrate the size of the portion of the plate 8 that needs to be bent. After the calibration is completed, it is removed from the support block 3. For details, please refer to Figure 2 In specific applications, its actual shape can be designed into various shapes according to actual needs, and it is connected to the support block 3 through a threaded connection, so that the distance between the fixed-distance protrusion and the bending space can be adjusted to enhance its versatility.

[0059] In some optional embodiments, the above-mentioned plate bending device further includes:

[0060] The support plate 6 is connected to the support block 3 and can be used to place the plate 8.

[0061] In some optional embodiments, the above-mentioned plate bending device further includes:

[0062] The handle 7 is connected to the rotating block 2 so as to facilitate the rotating block 2 to be turned.

[0063] In some optional embodiments, in the above-mentioned sheet bending device, the support block 3 has an avoidance groove to avoid the formation of a protruding portion at the top of the portion of the sheet 8 that needs to be bent, thereby avoiding interference in the bending process of the sheet 8. Figure 5 As shown, the avoidance groove can be filled with blocks when it is not needed.

[0064] In some optional embodiments, in the above-mentioned sheet bending device, the corner portion is detachably mounted on the rotating block 2;

[0065] The support block 3 can protrude forward relative to the two sliders 1 to form a step structure. At this time, the corner portion installed on the rotating block 2 presents a step structure adapted thereto, and the required bending positions a, b, and c of the three positions A, B, and C to be bent on the plate 8 can be respectively extended between the corner portion and the two sliders 1 and the support block 3. The rotating block 2 is pressed downward to simultaneously press on the three positions A, B, and C of the plate 8 to be bent, so that the three positions A, B, and C of the plate 8 to be bent are bent from the required bending positions a, b, and c, and a plane with a step difference is formed at one time with high precision, such as Figure 6 As shown, this operation can be specifically applied to the processing of the top corners of the box body.

[0066] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
