Machining requirements for laser cutting process in large machinery manufacturing industry

发布时间：2017-10-09        分享到：

Metal laser cutting machine is more and more industry applications, with the continuous development of technology and manufacturing power to China's transfer, the future machinery manufacturing industry also highlights the higher processing requirements. Automotive industry, the ship industry, and so on the metal laser cutting machine industry has made a different processing requirements.

1, the car engine and body stamping parts production line with continuous, efficient, high reliability characteristics, the automotive industry can specifically study the characteristics of automotive parts and process, and the automotive industry to develop a common research and development with a modular, series of complete sets Flexible production line. Flexible production line to the car engine head cylinder, cylinder head, crankshaft, connecting rod, camshaft, box and other processing parts for the object, to adapt to the flow of the production module can quickly reorganize the production line, grasp the performance evaluation, error traceability, Quality control and management integration technology, the development of high-speed precision, reliable performance of CNC cutting machine, at the same time with high-speed reclaiming, auxiliary equipment such as a deburring function.

2, large-scale ship hubs concentrated in the high-power diesel engine chassis, rack, cylinder block, cylinder head, piston rod, cross head, connecting rod, crankshaft, and gearbox drive shaft, rudder shaft and propeller, The processing material of the hub is made of special alloy steel, usually small batch processing, requiring metal laser cutting machine processing rate of 100%. Hub processing parts with heavy weight, complex shape, high precision, difficult processing and so on. Large ship hub parts need to have high power, high reliability and multi-axis heavy, ultra-heavy CNC cutting machine.

3, power plant hub processing parts of the weight, special shape, high precision, difficult processing, expensive, such as nuclear power plant pressure vessel single weight of 400 to 500 tons, large steam turbines and generators of the rotor weighs more than 100 tons, Reliable work for more than 30 years. Therefore, the power plant equipment required for the manufacture of CNC cutting machine is characterized by large size, high stiffness, high reliability.

4, the typical structure of the aviation industry is characterized by a large number of the overall structure of thin-walled, complex shape. In order to increase aircraft maneuverability, increase payloads and voyages, reduce costs, make lightweight designs and widely use new lightweight materials. Now a large number of aluminum, high temperature alloys, titanium, high strength steel, composite materials, engineering ceramics. Complex structure of thin-walled parts, honeycomb parts complex shape, holes, holes, grooves, ribs and so more, poor process rigidity. According to the structural characteristics and processing requirements of the aerospace industry, it is required that the metal laser cutting machine has enough rigidity, simple operation, clear man-machine interface, require spline interpolation and process average control to reduce the influence on the machining accuracy at the corner, With on-line measurement simulation function.
