Detailed Description
The present invention will be further explained with reference to the accompanying drawings. The drawings are for illustrative purposes only and are not to be construed as limiting the patent.
In order to explain the embodiment more simply, some parts of the drawings or descriptions that are well known to those skilled in the art but are not relevant to the main content of the present invention will be omitted. In addition, some components in the drawings may be omitted, enlarged or reduced for convenience of description, but do not represent the size or the entire structure of an actual product.
Example 1
As shown in fig. 1, 2 and 3, the present invention provides a shear blade structure, which comprises a shear blade main body 1, wherein the inner edge of the shear blade main body, i.e. the lower edge of the shear blade main body in fig. 1, is provided with a cutting edge 11, in this embodiment, the cutting edge 11 is an arc-shaped cutting edge, i.e. the cutting edge 11 bends upwards in a horizontal direction with a certain radian, the inner side surface of the shear blade main body 1 is provided with a cutting edge avoiding surface 2, a cutting edge meshing plane 3 is arranged between the cutting edge avoiding surface 2 and the cutting edge 11, the width W of the cutting edge meshing plane 3 is 0.6mm, the cutting edge avoiding surface 2 is an arc-shaped concave surface in this embodiment, the arc-shaped concave surface is arranged to be lower than the cutting edge meshing plane 3, the arc-shaped concave surface extends to the outer edge 12 of the shear blade main body 1, i.e. the upper edge of the shear blade main body 1 in fig, namely, the height of the outer edge 12 is 0.2mm lower than the height of the blade occlusion plane 3, in this embodiment, the maximum distance between the arc-shaped concave surface and the blade occlusion plane 3 in the direction perpendicular to the blade occlusion plane is set to be 0.4mm, so as to ensure that the height difference H between the outer edge of the arc-shaped concave surface, namely, the outer edge 12 of the shear blade main body and the blade occlusion plane 3 can reach 0.2 mm. Like this, when cutting the piece main part 1 and another piece main part 1 interlock, blade 11 with there is the clearance between blade interlock plane 3 and the blade face 2 of dodging of another piece main part 1, blade 11 promptly and blade interlock plane 3 can not avoid with the blade face 2 contact friction of dodging of another piece main part 1.
Example 2
This embodiment is similar to embodiment 1 in structure, and is different from embodiment 1 in that the width W of the blade occlusion plane 3 is 0.2mm, the maximum distance between the arc-shaped concave surface and the blade occlusion plane 3 in the direction perpendicular to the blade occlusion plane is set to be 0.3mm, and the height difference H between the blade occlusion plane 3 and the outer edge 12 of the shear blade main body 1 is 0.1 mm.
