Sheet metal cutting device and its usage method

Abstract

This invention relates to a sheet metal cutting device and its method of use, suitable for cutting one side of multiple sheet metals. The sheet metal cutting device includes: a body, a first cutting structure, and a second cutting structure. The first cutting structure has a first cutting part, and the first cutting part has a pair of first cutting areas and a first non-cutting area. The second cutting structure has a second cutting part, and the second cutting part has a second cutting area and a pair of second non-cutting areas. The first cutting part can cut one side of the sheet metal to form a convex structure, and the second cutting part can cut one side of the sheet metal to form a concave structure, and the convex and concave structures can cooperate with each other. Therefore, this invention can achieve a flat and stable joint of two sheet metals through cutting.

Claims

1.

Furthermore, each first cutting zone has a plurality of first through holes, and each second cutting zone has a plurality of second through holes. Each first cutting element is disposed around the periphery of each first through hole, and each second cutting element is disposed around the periphery of each second through hole. The first guide groove is fitted onto one side of the plate, allowing the first cutting element to cut along the length direction of one side of the plate to form a convex structure. The second guide groove is fitted onto one side of the plate, allowing the second cutting element to cut along the length direction of one side of the plate to form a concave structure. The two plates can be interlocked through the convex structure and the concave structure.

2. The sheet metal cutting apparatus as described in claim 1, wherein, The first perforations are arranged alternately with each other, and the second perforations are arranged alternately with each other.

3. The sheet metal cutting apparatus as described in claim 2, wherein, The spacing between each of the first perforations is less than or equal to the diameter of the first perforation, and the spacing between each of the second perforations is less than or equal to the diameter of the second perforation.

4. The sheet metal cutting apparatus as described in any one of claims 1 to 3, wherein, The first and second perforations are formed by punching, and the first and second cutting elements are burrs after punching.

5. The sheet metal cutting apparatus as claimed in claim 1, wherein, The main body has a first assembly groove and a second assembly groove on its two opposite sides, and the first cutting structure and the second cutting structure are respectively detachably disposed in the first assembly groove and the second assembly groove.

6. The sheet metal cutting device as claimed in claim 5, further comprising a plurality of fixing elements, wherein the first non-cutting area has a plurality of first assembly holes, and the pair of second non-cutting areas each have a plurality of second assembly holes, wherein, Each of the fixing elements passes through the first assembly hole and the second assembly hole, and the first cutting structure and the second cutting structure can be fixed in the first assembly groove and the second assembly groove respectively.

7. The sheet metal cutting apparatus as claimed in claim 1, wherein, The first cutting zone has a first inlet end and a first guide section, and the height of the first guide section gradually decreases towards the first inlet end. The second cutting zone has a second inlet end and a second guide section, and the height of the second guide section gradually decreases towards the second inlet end.

8. A method of using a sheet metal cutting device, comprising the following steps: step (A): preparing a sheet metal cutting device as described in any one of claims 1 to 7 and at least two sheet metals; step (B): cutting one side of one of the sheet metals through the first cutting part to form a convex structure, and cutting one side of the other sheet metal through the second cutting part to form a concave structure; and step (C): engaging the convex structure of one sheet metal with the concave structure of the other sheet metal to achieve the joining of the two sheet metals.
