Description

Technical Field

[0001] The utility model relates to the technical field of metal mesh production, and more specifically, to a shearing device for metal mesh production. Background Art

[0002] Metal mesh is made of metal sheets that are stamped and cold-drawn by machines. The mesh structure of the metal mesh allows air and liquid to pass through, and has good air permeability and water permeability. It is widely used in chemical machinery, silencer equipment, refrigeration equipment, hydraulic accessories, filtration equipment and other industries.

[0003] When producing metal mesh, the metal plate is first positioned and placed on the shearing machine workbench, ensuring that the edges are aligned with the machine guides. The metal plate is fixed with a clamp to prevent movement during the shearing process. Then, according to the selected mesh size and plate thickness, the shearing machine's blade gap, knife speed and feed speed are set. The shearing machine is started, and the blade moves according to the set parameters. The blade applies pressure to the metal plate to shear it into a mesh.

[0004] Since the blade of the shearing machine punches the metal plate from top to bottom to obtain a plurality of mesh holes, there will be burrs on the edges of the mesh holes at the bottom of the metal plate. In order to improve processing efficiency, the prior art adopts the method of installing a grinding wheel at the bottom of the metal plate to grind the edges of the mesh holes at the bottom of the metal plate to remove the burrs on the edges of the mesh holes. When the metal plate is thick and a large diameter mesh hole is punched, the grinding wheel grinds off the burrs and throws them out to one side through high-speed rotation. However, the temperature rises due to the high-speed friction between the grinding wheel and the burrs, resulting in an increase in the temperature of the burrs. As the grinding wheel rotates, the high-temperature burrs on one side are thrown into the interior of the large diameter mesh holes. The burrs that have been cooled will adhere to the inner wall of the mesh holes. Since the thickness of the metal plate is large, the thickness of the mesh holes is also large, and a large number of burrs can be stored inside the mesh holes, resulting in a reduction in the blocked area of ​​the mesh holes, thereby affecting the effective air and water permeability of the mesh holes.

[0036] In this embodiment, the implementation scenario is specifically as follows: after the shearing tool 33 is fixed on the shearing tool mounting seat 32, the metal plate 21 is pushed from one end of the processing table 2 into between the two sets of side plates of the support seat 3, and the linear drive mechanism 1 31 is started to push the shearing tool 33 to press down the metal plate 21, and the punching tool at the bottom of the shearing tool 33 punches out the mesh holes 22 on the metal plate 21.
