Description

Technical Field

[0001] The utility model relates to a metal plate processing technology, in particular to a metal plate stitching mechanism. Background Art

[0002] At present, forming building panels using composite materials has become one of the important development trends. Existing hollow building panels usually have panels on two surfaces and connecting support plates between the two panels. Since the connecting support plates are located between the two panels and are relatively fixed, building panels with suitable strength and stiffness can be formed. At the same time, due to their hollow structure, the weight of the hollow building panels can be significantly reduced.

[0003] Hollow building panels are usually formed by connecting multiple unit components. By changing the number of unit components, the hollow building panels can have a suitable area. The way of connecting multiple unit components is generally to overlap metal plates (including composite plates, multi-layer plates, etc.) between the unit components, and then use fasteners (rivets, screws, etc.) to fix the overlapping metal plates, thereby realizing the connection and fixation between unit components.

[0004] At present, using fasteners to realize the connection and fixation between unit components increases the process and raises the cost. How to improve the production efficiency of hollow building panels while ensuring the mechanical properties of hollow building panels is an important technical problem that needs to be solved by those skilled in the art. Summary of the Utility Model

[0005] For this reason, the utility model provides a metal plate stitching mechanism. Using this metal plate stitching mechanism, there is no need to use fasteners anymore, and the connection and fixation between metal plates can be realized by using the metal plates themselves, which improves the connection efficiency of metal plates and ensures the connection reliability. Of course, this mechanism can be used for the fixed connection of metal plates between hollow building panels and can also improve the production efficiency of hollow building panels.

[0006] The metal plate stitching mechanism provided by the present utility model includes a stitching cam and a stitching concave cam; a predetermined stitching gap is formed between the outer peripheral surface of the stitching cam and the outer peripheral surface of the stitching concave cam to allow the metal plate to be stitched to pass through; a stitching protrusion is provided on the outer peripheral surface of the stitching cam, and the protruding dimension of the stitching protrusion is greater than the stitching gap; a stitching depression is provided on the outer peripheral surface of the stitching concave cam; the stitching depression corresponds to the stitching protrusion to press a part of the metal plate to be stitched passing through the stitching gap into the stitching depression. By using this metal plate stitching mechanism, the stitching cam and the stitching concave cam can rotate simultaneously, and the metal plate to be stitched can pass through the stitching gap. The stitching depression corresponds to the stitching protrusion, and the metal plate to be stitched can be deformed under the action of the stitching protrusion. At the same time, the stitching depression provides space for the deformation of the metal plate, so that a part of the metal plate to be stitched is pressed into the stitching depression to achieve the connection and fixation between the overlapping metal plates. By using this metal plate stitching mechanism, fasteners do not need to be used anymore, and the connection and fixation between the metal plates can be realized by using the deformation of the metal plate itself, which improves the connection efficiency of the metal plates and ensures the connection reliability. Of course, this mechanism can be used for the fixed connection of the metal plates between the hollow building panels, and can also improve the production efficiency of the hollow building panels.

[0007] In an alternative technical solution, the radii of the outer peripheral surfaces of the stitching cam and the stitching concave cam are equal.

[0008] In a preferred technical solution, a plurality of the stitching protrusions are uniformly arranged on the outer peripheral surface of the stitching cam; a plurality of stitching depressions are uniformly arranged on the outer peripheral surface of the stitching concave cam; the arc length between adjacent two stitching protrusions is equal to the arc length between adjacent two stitching depressions, which can ensure the correspondence between the stitching protrusion and the stitching depression. By arranging multiple pairs of stitching protrusions and stitching depressions, a plurality of fixed connection points (stitching points) can be formed when the stitching cam or the stitching concave cam rotates one week, which improves the stitching efficiency and at the same time improves the connection reliability between the metal plates.

[0009] In a preferred technical solution, the rotation axes of the stitching cam and the stitching concave cam are arranged in parallel; in the moving direction of the metal plate to be stitched, the axis of the stitching concave cam is located behind the axis of the stitching cam. In this way, pressure can be applied to the metal plate to be stitched in advance, the force application time of the metal plate is prolonged, the springback of the metal plate is reduced, and the connection reliability of the stitching points of the metal plate is improved.

[0010] In a further preferred technical solution, the stitching cam is connected to a power source, and the stitching concave cam is powered by a gear mechanism to be connected to the stitching cam. In this way, the stitching concave cam and the stitching cam can rotate at a set speed ratio, which ensures the correspondence between the stitching protrusion and the stitching depression, reduces the matching deviation between the stitching protrusion and the stitching depression, and the consistency of the deformation of the stitching points of the metal plate, and improves the connection reliability of the stitching points of the metal plate.

[0011] In the preferred technical solution, the surface of the stitching protrusion is a frustum surface. This can better deform the metal plate and reduce the pressure springback.

[0012] Another metal plate stitching mechanism provided by the present utility model includes a stitching cam and a stitching concave cam; a predetermined stitching gap is formed between the outer peripheral surface of the stitching cam and the outer peripheral surface of the stitching concave cam to allow the metal plate to be stitched to pass through.

[0013] The outer peripheral surface of the stitching cam is provided with stitching protrusions, and the protruding size of the stitching protrusions is greater than the stitching gap; the outer peripheral surface of the stitching concave cam is provided with an annular stitching groove; the stitching groove corresponds to the stitching protrusions to press a part of the metal plate to be stitched passing through the stitching gap into the stitching groove. Compared with the previous metal plate stitching mechanism, in this metal plate stitching mechanism, the stitching protrusions and the stitching grooves are opposite to each other, and the stitching grooves have a larger compatible space. The position of the metal plate stitching points is determined by the position of the stitching protrusions, which can greatly ensure the consistency of the metal plate stitching points.

[0014] In the preferred solution, a plurality of the stitching protrusions are uniformly arranged on the outer peripheral surface of the stitching cam, so that a plurality of fixed connection points (stitching points) can be formed when the stitching cam or the stitching concave cam rotates one week, improving the stitching efficiency and at the same time improving the reliability of the connection and fixation between the metal plates.

[0015] In the preferred technical solution, the rotation axis of the stitching cam and the rotation axis of the stitching concave cam are arranged in parallel; in the moving direction of the metal plate to be stitched, the axis of the stitching concave cam is located behind the axis of the stitching cam; in a more preferred solution, in the moving direction of the metal plate to be stitched, the distance between the axis of the stitching concave cam and the axis of the stitching cam is greater than the stitching gap. This can apply pressure to the metal plate to be stitched in advance, extend the force application time of the metal plate, reduce the springback of the metal plate, and improve the reliability of the connection of the metal plate stitching points.

[0021] The following describes the detailed implementation manners provided by the present utility model.

[0022] Please refer to Figure 1 , Figure 1 , which is the working state diagram of the metal plate stitching mechanism in the first embodiment of the present utility model. In this embodiment, the metal plate stitching mechanism includes a stitching cam 100 and a stitching concave cam 200. Both the stitching cam 100 and the stitching concave cam 200 are made of metal materials, have high strength, and are rotatably installed on a suitable frame. The stitching cam 100 and the stitching concave cam 200 can both be power-connected to a suitable driving mechanism to rotate at a predetermined speed.

[0023] As shown in the figure, a predetermined stitching gap X is formed between the outer peripheral surface of the stitching cam 100 and the outer peripheral surface of the stitching concave cam 200 to allow the metal plate to be stitched to pass through. The suitable stitching gap can be determined according to the size of the metal plate to be stitched. For example, if the metal plate to be stitched is a four-layer galvanized aluminum plate with a total thickness of about 8 mm, the stitching gap X can be about 8.3 mm to allow the metal plate to be stitched to pass through while ensuring the pressing effect.

[0024] The outer peripheral surface of the stitching cam 100 is provided with a stitching protrusion 110, and the protruding size of the stitching protrusion 110 is greater than the stitching gap X to enter the stitching recess 210 described below. The shape and size of the stitching protrusion 110 should match the shape and size of the stitching recess 210 described below.

[0025] The outer peripheral surface of the stitching concave cam 200 is provided with a stitching recess 210; the stitching recess 210 corresponds to the stitching protrusion 110 to press a part of the metal plate to be stitched passing through the stitching gap X into the stitching recess 210.

[0026] Using this metal plate stitching mechanism, the stitching cam 100 and the stitching concave cam 200 can be rotated simultaneously, and the metal plate to be stitched can pass through the stitching gap X along Figure 1It moves in the direction of arrow R. The stitching recess 210 corresponds to the stitching projection 110. The metal plate to be stitched can be deformed under the action of the stitching projection 110. At the same time, the stitching recess 210 provides space for the deformation of the metal plate, so that a part of the metal plate to be stitched is pressed into the stitching recess 210, realizing the connection and fixation between the overlapping metal plates. Using this metal plate stitching mechanism, fasteners are no longer needed, and the connection and fixation between metal plates can be realized by the deformation of the metal plate itself, improving the connection efficiency of the metal plate and ensuring the connection reliability. Of course, this mechanism can be used for the fixed connection of metal plates between hollow building panels, and can also improve the production efficiency of hollow building panels.

[0027] In this embodiment, the radii of the outer circumferential surfaces of the stitching cam 100 and the stitching cam 200 are equal. Five stitching projections 110 are evenly arranged on the outer circumferential surface of the stitching cam 100; five stitching recesses 210 are evenly arranged on the outer circumferential surface of the stitching cam 200; in this way, it can be ensured that the arc lengths between adjacent two stitching projections 110 are equal to the arc lengths between adjacent two stitching cams 200, and the correspondence between the stitching projection 110 and the stitching recess 210 can be ensured. According to the quantitative relationship between the arc length, the radian and the radius of the outer circumferential circle, if the radii of the outer circumferential surfaces of the stitching cam 100 and the stitching cam 200 are not equal, appropriate settings can also be made to make the stitching cam 100 have a suitable size, set a suitable number of stitching projections 110, and at the same time make the stitching cam 200 have a suitable size and set an appropriate number of stitching recesses 210, as long as it can be ensured that the arc lengths between adjacent two stitching projections 110 are equal to the arc lengths between adjacent two stitching cams 200, and the correspondence between the stitching projection 110 and the stitching recess 210 can be ensured.

[0028] Setting multiple pairs of stitching projections 110 and stitching recesses 210 can form multiple fixed connection points (stitching points) when the stitching cam 100 or the stitching cam 200 rotates one week, improving the stitching efficiency and at the same time improving the connection reliability between metal plates.

[0029] In this embodiment, the rotation axes of the stitching cam 100 and the stitching cam 200 are arranged in parallel; in the moving direction of the metal plate to be stitched (arrow R direction), the axis of the stitching cam 200 can be located behind the axis of the stitching cam 100. In this way, pressure can be applied to the metal plate to be stitched in advance, prolonging the force application time of the metal plate, reducing the springback of the metal plate, and improving the connection reliability of the stitching points of the metal plate.

[0030] To ensure the correspondence between the stitching protrusions 110 and the stitching depressions 210, the stitching cam 100 can be connected to a power source, and the stitching cam 200 is power-connected to the stitching cam 100 through a gear mechanism. This can cause the stitching cam 200 and the stitching cam 100 to rotate at a set speed ratio, reduce the matching deviation between the stitching protrusions 110 and the stitching depressions 210, improve the consistency of the deformation of the metal plate stitching points, and improve the reliability of the connection of the metal plate stitching points.

[0031] The surface of the stitching protrusion 110 can be a frustum surface. This can better deform the metal plate and reduce the pressure springback. Of course, other shapes can also be selected to control the deformation of the metal plate and ensure the reliability of the connection of the overlapping metal plates.

[0032] Please refer to Figures 2 to 4 , Figure 2 which is the working state diagram of the metal plate stitching mechanism in the second embodiment of the present invention, Figure 3 which is the working state diagram of the metal plate stitching mechanism from another angle in the second embodiment of the present invention, Figure 4 which is the three-dimensional structure diagram of the metal plate stitching mechanism in the second embodiment of the present invention. Another metal plate stitching mechanism provided by this embodiment includes a stitching cam 100 and a stitching cam 200; a predetermined stitching gap X is formed between the outer peripheral surface of the stitching cam 100 and the outer peripheral surface of the stitching cam 200 to allow the metal plate to be stitched to pass through. Similarly, the stitching cam 100 and the stitching cam 200 are rotatably installed on a suitable frame.

[0033] The outer peripheral surface of the stitching cam 100 is provided with stitching protrusions 110, and the protruding dimension of the stitching protrusions 110 is greater than the stitching gap X; the outer peripheral surface of the stitching cam 200 is provided with an annular stitching groove 220; the stitching groove 220 corresponds to the stitching protrusions 110 to press a part of the metal plate to be stitched passing through the stitching gap X into the stitching groove 220. It can be understood that the stitching groove 220 can be a complete ring or a partial ring structure to correspond to the stitching protrusions 110.

[0034] Compared with the previous metal plate stitching mechanism, in this metal plate stitching mechanism, the stitching protrusions 110 and the stitching grooves 220 are opposite to each other, and the stitching grooves 220 have a larger compatible space and can correspondingly correspond to multiple stitching protrusions 110 without limitation. The position of the metal plate stitching point is determined by the position of the stitching protrusions 110, which can ensure the consistency of the metal plate stitching points to a greater extent. In addition, the diameter dimensions of the stitching cam 100 and the stitching cam 200 can be restricted, and there is more freedom. In this embodiment, the contour dimension of the stitching cam 200 can be relatively small to save space.

[0035] In this embodiment, a plurality of the stitching protrusions 110 are evenly arranged on the outer peripheral surface of the stitching cam 100, and a plurality of fixed connection points (stitching points) can be formed when the stitching cam 100 or the stitching concave cam 200 rotates one week, improving the stitching efficiency and at the same time improving the reliability of the connection and fixation between the metal plates.

[0036] In this embodiment, the rotation axes of the stitching cam 100 and the stitching concave cam 200 are arranged in parallel; in the moving direction of the metal plate to be stitched, the axis of the stitching concave cam 200 is located behind the axis of the stitching cam 100; in a more preferred solution, in the moving direction of the metal plate to be stitched, the distance S between the axis of the stitching concave cam 200 and the axis of the stitching cam 100 is greater than the stitching gap X. This can apply pressure to the metal plate to be stitched in advance, extend the force application time of the metal plate, reduce the springback of the metal plate, and improve the reliability of the connection of the stitching points of the metal plate.

[0037] Although the preferred embodiments of the present invention have been described in the above description, those skilled in the relevant technical field can understand that many changes or modifications can be made in the details of design, construction or operation without departing from the scope required by the present invention.
