Description

[0002] FRP mesh is a mesh made of fiber-reinforced composite materials. It is light and hard, non-conductive, has high mechanical strength and corrosion resistance. Due to its excellent mechanical properties, it is widely used in bridge engineering, various construction projects, marine engineering, underground engineering and other projects.

[0003] At present, when producing FRP mesh, multiple FRP wires are usually tied and fixed, and then combined with cutting, gluing, drying and other processes to form a mesh structure. Among them, when cutting the mesh, the conventional operation is to use a cutter to punch and cut.

[0004] Due to the structural limitations of the stamping cutter die, the mesh cannot move freely at the cutting die. In the ordinary cutting process, the mesh can only be taken manually and placed under the cutter for alignment and cutting. After the stage is completed, the mesh is manually taken out and placed in the next flow process. This process is very cumbersome, and conventional punching and cutting dies mostly need to use electric cylinders with electrical components such as sensors to control the lifting of the upper die with the cutter to ensure accuracy. The overall energy consumption is large, the life of components is short, and the production cost is high. Ordinary cylinders are difficult to meet the requirements of high precision and long service life.
