With the increase of steel structure engineering and market requirements in recent years, the original H-beam and I-beam construction has been difficult to meet the requirements of users, while the pipe network structure with steel pipe as the main material is gradually becoming the steel structure industry. trend. How to realize the pipe network welding of steel pipe, the key technical problem is to realize the bevel cutting of the steel pipe, the equipment that needs to be used is the intersecting line CNC cutting machine, compared with the traditional CNC cutting machine equipment, the intersecting line CNC cutting The biggest feature of the machine is the three-dimensional groove special-shaped cutting of the steel pipe and other materials through the multi-dimensional movement of the torch.
Judging from the types of CNC cutting machines currently on the market, they can be divided into two types. One is for simple intersecting wire cutting, and the other is for intersecting wire NC cutting machines for groove cutting. . The former is similar to the traditional CNC cutting equipment, mainly to complete the right angle truncation of the steel pipe; and the latter is the special multi-axis linkage intersecting line CNC cutting machine that we need to focus on the pipe network.
As for the type of CNC cutting machine with multi-axis linkage intersecting lines, it is mainly based on the linkage axis and design axis of the cutting machine. The main products include nine-axis five linkage series, five-axis four linkage series and three-axis two linkage systems. Among them, the three-axis two linkage series intersecting wire cutting machine is a simple steel tube right angle cutting equipment.
The multi-axis linkage intersecting line CNC cutting machine is mainly used for the thermal cutting of intersecting lines and ends of various pipeline systems. The cutting mode is divided into flame cutting and plasma cutting according to the material of the material to be cut. The former applies to the workpiece material generally For low-carbon steel, the latter applies to copper nickel tubes, stainless steel tubes and other materials.
1. CNC flame intersecting wire cutting machine, cutting with a large thickness of carbon steel cutting ability, cutting cost is low, but there is a large cutting deformation, cutting accuracy is not high, but the cutting speed is low, the cutting warm-up time, a long piercing time, It is difficult to adapt to the needs of fully automated operation. Its application is mainly limited to carbon steel, large thickness plate cutting, in the middle, thin carbon steel plate cutting will be replaced by plasma cutting.
2. CNC plasma cutting machine, plasma cutting has a wide cutting area, can cut all metal pipe, cutting speed, high efficiency, cutting speed up to 10m/min or more. The use of fine plasma cutting has brought the cutting quality close to the level of laser cutting. Currently, with the maturity of high-power plasma cutting technology, the cutting thickness has exceeded 100 mm, and the cutting range of the CNC plasma intersecting wire cutter has been broadened.
