China's oil pipeline construction, large-scale construction machinery, shipbuilding, vehicle manufacturing, etc. have promoted China's large and heavy-duty CNC cutting equipment, profile bending equipment, heavy-duty coiling machines, ship plate presses, large multi-station presses, etc. The advancing of new, special and large forging equipment at the advanced level.
The new technical equipment of sheet metal processing - CNC laser cutting machine is growing rapidly. China's slightly large-scale sheet metal machinery manufacturers have developed laser cutting machines. In 2010, China produced more than 1,000 high-power laser cutting machines of more than kW, which became the highlight of the rapid growth of China's sheet metal machinery. The structure of the main body of the laser cutting machine, the auxiliary equipment, the workpiece and the working occasion are the same as those of the CNC punching and shearing machine. Therefore, the laser cutting machine is classified into the forging equipment to be managed.
With the program-controlled hydraulic hammer as the representative, the forging hammer equipment has made great progress in the direction of energy saving, environmental protection and numerical control. Similarly, the screw press adopts numerical control technology and combines advanced switched reluctance motor technology to become an electric screw press with precise and controllable energy and bottom dead center position. At the same time, China has been able to manufacture a heavy-duty grinding ring machine with automatic control of the laser measurement and rolling process, which can roll ring pieces with a diameter of 10 m. In addition, CNC tube bending machines, riveting machines, spinning machines, pendulum mills, radial forging machines and other small door products have also developed a number of enterprises, and the product level has reached the advanced level in foreign countries.
At present, Shandong Jinan, Jiangsu Yangzhou and other places have become China's sheet metal machinery industry gathering area. On the whole, the innovation capability and product technology level are leading domestically and have good development prospects.
Since the “Eleventh Five-Year Plan”, forging equipment with special structure and special functions that are oriented to new processes and meet new technological requirements has also emerged. For example, isothermal forging equipment, hot stamping equipment, electromagnetic forming machines, special material forging equipment, etc.
The rapid development of power generation equipment, large aircraft, ships, aerospace, military aircraft, vehicles, etc. has greatly promoted the advancement of large-scale forging and extrusion equipment, making China a heavy-duty free forging hydraulic press and heavy-duty forging hydraulic press with large tonnage and quantity. Many countries. Moreover, the tonnage of the die forging hydraulic press will continue to refresh.
