Description

Technical Field

[0001] The invention relates to the field of metal mesh manufacturing, and in particular to a metal mesh cutting tool, a tool body structure, a metal mesh and a metal mesh preparation method. Background Art

[0002] Currently, metal mesh is widely used in various fields. Since metal mesh can be made of various metals and metal mesh made of different metals have different properties, metal mesh has multiple uses; for example: metal mesh made of steel can be used in the construction field for reinforcement or as a fence; metal mesh made of nickel can be used in printing or perforated film manufacturing and other fields; metal mesh made of copper or silver can be used on photovoltaic cells in the photovoltaic industry. The crossed metal lines of the metal mesh play the role of main grid lines and fine grid lines, realizing the convergence and output of current generated by photovoltaic cells.

[0003] The existing metal mesh adopts a grid structure composed of crossed metal lines. The metal mesh is usually woven from metal lines. The arrangement and line width of the metal lines vary depending on the purpose. The smaller the width of the metal lines of the metal mesh, the greater the density of the metal lines of the metal mesh, and the more difficult it is to process.

[0004] Metal cutting tools are commonly used tools for cutting metal. The sharp tool edge can be used to cut metal sheets into any shape. The existing metal cutting tools have only one cutting edge, so it takes many cuts to cut the metal sheet into a metal mesh structure using the existing metal cutting tools. In particular, the thinner the metal line, the more difficult it is to cut.

[0005] In view of the above problems, it is necessary to study a metal mesh cutting tool, a tool body structure, a metal mesh and a metal mesh preparation method, wherein the metal mesh cutting tool can quickly cut metal sheets into metal meshes. Summary of the invention

When cutting, the two cutting edges can quickly cut the metal sheet, and the setting of the groove enables the metal sheet to be cut to form metal lines; 2. When the metal mesh cutting tool of the present invention is in use, each blade body of the grid cutting part of the metal mesh cutting tool interacts with the light roller or the operating platform to cut the metal sheet, and the area corresponding to the groove of the metal sheet and the blade body will not be cut, that is, the metal mesh cutting tool only relies on the two cutting edges of each blade body of the grid cutting part to cut the metal sheet, and the metal mesh cutting tool only cuts the metal sheet on both sides of the groove of the blade body, so the area corresponding to the groove of the metal sheet and each blade body of the grid cutting part forms the metal line of the metal mesh after cutting in the metal sheet; and because each blade body of the grid cutting part of the metal mesh cutting tool constitutes a closed grid structure, the metal mesh cutting tool of the present invention can cut the metal sheet at one time, greatly improving the cutting efficiency of the metal mesh, and the operation is simple. At the same time, by designing grid cutting parts with different distributions on the metal mesh cutting tool, metal meshes with different grid structures can be obtained, and metal lines of different widths can be obtained by adjusting the width of the groove.
