Processing requirements of laser cutting machine in large-scale machinery manufacturing

Guide: Metal laser cutting machines are used in more and more industries. With the continuous development of science and technology and the transfer of major manufacturing countries to my country, the machinery manufacturing industry will also highlight higher processing requirements in the future. The automobile industry, the industry, etc. have put forward different processing requirements for the metal laser cutting machine industry.

1. The production line of automotive ideas and body stamping parts has the characteristics of continuous, high efficiency, and high reliability. The automotive industry requires specializing in the process characteristics of automotive parts, exchanges with the automotive industry, and joint research and development of modules. A complete and serialized flexible production line. The flexible production line focuses on the processing of hub machining parts such as automobile engine cylinder blocks, cylinder heads, crankshafts, connecting rods, camshafts, boxes, etc. The rapid combination of modules suitable for mixed production can reorganize the production line, and grasp the performance evaluation, error traceability, Quality control and management integration technology, development of high-speed, precise, reliable CNC cutting machine, at the same time with high-speed reclaiming, auxiliary equipment such as deburring function.

2. Large hub machining parts are concentrated in the base, frame, cylinder block, cylinder head, piston rod, crosshead, connecting rod, crankshaft, and transmission shaft and rudder shaft of the high-power diesel engine And thrusters, etc., the material of the hub processed parts is special alloy steel, which is generally processed in small batches, and the metal laser cutting machine is required to process a finished product rate of 100%. Hub processing parts have the characteristics of heavy weight, complex appearance, high precision, and high processing difficulty. The processing of large hub parts requires a heavy-duty and super-heavy CNC cutting machine with high power, high reliability and multi-axis.

3. The processing parts of the power generation equipment hub are heavy, special shape, high precision, difficult to process, and expensive. For example, the pressure vessel of nuclear power station weighs 400~500 tons, and the rotor of large steam turbine and generator Pieces weighing more than 100 tons require reliable work for more than 30 years. Therefore, the numerical control cutting machine required for the manufacture of power generation equipment hub parts is characterized by large specifications, high rigidity, and high reliability.

4. The structural characteristics of typical industrial parts are the large number of overall thin-walled structures with complex shapes. In order to increase the maneuverability of the device, increase the payload and range, reduce the cost, carry out lightweight design and widely use new lightweight materials. Nowadays, aluminum alloys, high-temperature alloys, titanium alloys, high-strength steels, composite materials, engineering ceramics, etc. are widely used. Thin-walled parts and honeycomb parts with complex structures have complex shapes, with many holes, cavities, grooves, ribs, etc., and poor process rigidity. According to the structural characteristics and processing requirements of industrial processed parts, the metal laser cutting machine is required to have sufficient rigidity, simple operation, clear man-machine interface, spline interpolation, and process average control to reduce the impact on the processing accuracy of the corners.
