Description

Technical Field

[0001] The utility model relates to a positioning device for metal mesh processing, in particular to a positioning device for metal mesh processing, and belongs to the technical field of metal mesh processing. Background Art

[0002] Metal mesh is made of stainless steel, aluminum-magnesium alloy wire, heavy brass, carbon steel and other alloy materials, and then woven into meshes of different shapes, densities and specifications according to needs. Metal mesh is woven into a mesh with metal wire. In order to meet the use requirements of the metal mesh, the metal mesh will be further processed. At this time, a positioning device is needed to assist in positioning the metal mesh that needs to be processed.

[0003] A positioning device for metal mesh processing is disclosed in the Chinese patent application disclosure CN217371435U. This device solves the problem that most existing methods of metal mesh processing rely on heavy objects to press down or other objects to block the metal mesh, and the positioning effect is general and the process is cumbersome. This positioning device for metal mesh processing has the advantage of convenient positioning and is worthy of promotion.

[0004] However, in the process of implementing the technical solution of the above patent, the positioning device fixes the metal mesh at two sides of the metal mesh. When the edge of the metal mesh needs to be processed, this method of fixing the edge of the metal mesh will hinder the processing, resulting in subsequent processing being more difficult. In addition, most of the existing positioning devices cannot adjust the width of the desktop. Sometimes the edge of the metal mesh needs to extend beyond the desktop for processing. When grinding, deburring, and other processing are performed on the edge of the metal mesh, the metal mesh needs to extend beyond the desktop for operation. The width of the desktop cannot be adjusted so that both sides of the metal mesh cannot extend beyond the edge of the desktop at the same time, resulting in the inability to flexibly perform the positioning operation.
