Breaking the monopoly of foreign monopoly of the first spiral bevel gear dry cutting machine
240 M3/h Concrete Batching Plants During the maintenance of the mixing station, the main power supply must be cut off, the door of the distribution cabinet must be locked, and the key should be kept by the electrician.Power cutting and transmission must be operated by electrician.When starting the belt conveyor, mixing host, and other motors, it is necessary to observe whether there are people or other sundry things on the motor, in order to prevent injury or damage to the equipment when starting. When cleaning, it is strictly prohibited to flush the electric motor, electrical switch, solenoid valve and other electrical appliances with water to prevent electric shock and damage to electrical equipment.When the mixer is working, it is forbidden to stand in the discharging area.Non-operators are forbidden to enter the control room, smoking and doing things unrelated to the operation are prohibited.There is no operator in the operating room. Power must be cut off and doors and Windows must be locked before leaving.

In recent years, with the rapid development of China's automobile, construction machinery and other industries, the demand for precision spiral bevel gears is increasing, and the annual demand is about 6 million sets. However, spiral bevel gear machining has always used the wet cutting method, that is, oil and water are used to cool the large amount of heat generated when the machine tool cuts parts. The process is complicated and the energy consumption is huge. Wonderfully, scientists have discovered that when mechanical cutting reaches a certain high speed, cutting is instantaneously completed, and the amount of heat generated is rather small. Without cooling, heat can be dissipated directly in the air. However, to find and maintain such a critical state requires a systematic breakthrough in CNC machine tool rigidity, structure, processing software, and process methods. Previously, only one company in the United States and Germany had mastered the spiral bevel gear dry cutting technology.
Li Guosheng, chairman of “Zhongda Chuangyuan†introduced that they have established the first CNC spiral bevel gear research institute, gear testing room, software and electrical testing room, etc. After numerous trials, they have finally overcome this major technical problem. The reporter saw at the scene that dry-cutting machining of a large gear of a car takes less than 18 minutes than wet cutting, and the power consumption is only about 25% of wet cutting. No oil or water cooling is required to achieve zero pollution. Moreover, the price of such a machine tool is less than half that of similar foreign products.
