Description

Technical Field

[0001] The utility model relates to the technical field of water jet cutting machines, in particular to a water jet cutting machine crossbeam guide rail structure and a water jet cutting machine. Background Art

[0002] Waterjet cutting is a special processing method that uses a supercharger to pressurize water. The water gains pressure energy and then sprays out from a tiny nozzle, converting the pressure energy into kinetic energy, thus forming a high-speed jet. Cutting uses the kinetic energy of this high-speed jet to impact and destroy the workpiece, thereby achieving the purpose of cutting and forming. No heat is generated during the cutting process, so all metal and non-metal materials can be cut, especially materials that are difficult to cut by various thermal cutting methods. Waterjet cutting has the following characteristics: fast and smooth incision, no dust, no thermal deformation, no pollution, reduced material waste, and little influence by material texture. Because of its low cost, easy operation, and high yield rate, waterjet cutting is becoming the mainstream cutting method in industrial cutting technology.

[0003] Most existing water jet cutting machines use a single-arm cantilever beam. The single-arm structure cannot stabilize the gravity of the cantilever beam, resulting in uneven force on the single-arm structure and unstable movement of the cantilever beam. At the same time, the single arm's own gravity causes imbalance and deformation, so high-precision processing of the cutting head installed on the cantilever beam cannot be guaranteed.

[0004] To this end, we propose a water jet cutting machine beam guide structure and a water jet cutting machine. Utility Model Content
