1, senior equipment "temptation" gear processing

In recent years, with the development of the automotive industry, the demand for gears has been increasing, and the demand for gear processing efficiency, quality and cost has become higher and higher. At the same time, the state has intensified its efforts to protect the environment. In addition, as domestic labor costs are high, recruitment problems become increasingly serious. Therefore, the automobile gear enterprise is eager to realize the automation, high efficiency, low cost and green environmental protection of the product processing.

"We have innovated and optimized the CNC hobbing machine from many aspects to meet the requirements of high precision, high efficiency, high stability and green environmental protection gear hobbing." Wang Jianwen, Minister of technology at the Pml Precision Mechanism Ltd in Zhejiang, shared the industry's comprehensive program for hobbing and shaving gear.

Nanjing high Chuansi open CNC Equipment Manufacturing Co., Ltd. deputy chief engineer Wang Bin said: "intelligent manufacturing is the automobile gear manufacturing industry represent the general trend, more and more enterprises begin to consider upgrading of equipment, hope to choose more advanced automation equipment."

2 、 drive system test, use new and high technology

The steady state endurance test of gear box includes transmission efficiency test, high speed test, temperature rise test, back drag test, torque change test, type test, static torsion test and cycle test. "We have developed test technology and equipment for automotive transmission," said Professor Zhang Zhigang, vice president of vehicle engineering at Chongqing University of Technology."

The dynamic endurance test of gear box mainly includes dynamic condition simulation test and dynamic load spectrum fatigue test. Zhang Zhigang introduced: "we have now broken through the working conditions of load spectrum acquisition and processing, working load spectrum simulation test, electrical inertia simulation test and engine simulation test technical difficulties."."

The gear box fault monitoring system for durability early order analysis method, eliminate the traditional frequency analysis of variable speed motion "frequency ambiguity" method, to solve the key technical problems of extraction gear rotating parts the frequency characteristics of signals.

3, eliminate "dumb equipment" aiming intelligent manufacturing

Most of the domestic automotive gear parts factory is still using the CNC system, commonly known as "dumb" equipment". To realize intelligent manufacturing, enterprises must first eliminate the "dumb device", and increase the distributed data acquisition module for equipment to collect and transmit data.

The high price of imported distributed controllers determines that it can not be widely used in small and medium enterprises, and restricts the upgrading of small and medium-sized enterprises for intelligent manufacturing. "Our products will change the status quo," Lu said. It is suitable for domestic small and medium-sized enterprises to manage and price requirements."

Deputy Secretary General of Chinese Automobile Industry Association in Shi Jianhua introduction of the development trend of the global automotive industry said: "informatization can fully optimize the internal management and operational efficiency, and construct the information exchange mechanism effectively, reduce the cost. Intelligent manufacturing will improve the consistency of products while improving efficiency and reducing costs."
