Description

Technical Field

[0001] The present invention relates to the field of lightning protection metal meshes, and particularly to a production and annealing device for lightning protection metal meshes. Background Art

[0002] As a key protective material, the lightning protection metal mesh needs to have high electrical conductivity, corrosion resistance, and uniform mechanical properties. Its traditional production process includes multiple independent processes such as unrolling of metal strips, cutting, stretching into a mesh, annealing treatment, cooling, and winding. In the prior art, each process is mostly completed by dispersed equipment. For example, after the metal strip is unrolled by an unrolling machine, it needs to be manually transferred to an independent cutting machine for fixed-length cutting, then stretched into a mesh structure by a mesh stretching machine, and then transferred to an annealing furnace for heat treatment. Finally, it is manually wound after cooling.

[0003] This segmented production method has the following problems:

[0004] 1. Low efficiency in process connection: Each link relies on manual transfer, resulting in a long production cycle, high material loss, and easy deformation or contamination of the strip due to improper operation;

[0005] 2. Unstable annealing quality: Traditional annealing furnaces mostly use static heating, and the metal mesh is prone to local overburning or incomplete recrystallization due to uneven heating, affecting electrical conductivity and mechanical strength;

[0006] 3. Insufficient automation: The cutting accuracy depends on manual adjustment, the control of the mesh stretching tension is inaccurate, and it is easy to cause deviation in the mesh hole size; there is a lack of atmosphere protection during the cooling process, and the surface of the metal mesh is prone to oxidation;

[0007] 4. Defects in winding and plastic sealing: Existing winding equipment is difficult to perform plastic sealing packaging synchronously, and secondary processing is required, increasing costs and the risk of pollution.

[0008] Therefore, there is an urgent need to develop an integrated and high-precision production and annealing device for lightning protection metal meshes to achieve full-process automatic control from unrolling to plastic sealing, and improve the annealing uniformity and anti-oxidation performance.
