Bearing industry requirement for numerical control equipment
The development of Chinese bearing industry key: as the national economy and the continuous development of industrial product technology, all walks of life there is an increasing demand for bearing and technical requirements also more and more high, general bearing the trend of specialization is more and more obvious. Bearing phyletic and various, but the development of key should be large amount and high technical content of products, especially in the current domestic is insufficient, need a large number of imported bearings and can represent the development direction of large-scale, precision, complex, combination bearings, especially in automotive industry, machine tool industry, railway industry, petroleum and chemical machinery, textile machinery and metallurgy industry and replace the imported bearing.
Bearing the type, quantity, level, production concentration have significant influence on the development of the whole bearing industry. As a result, is focus on the development of bearing industry fields. Low vibration, no sound, high precision bearings, composite bearings, oil chemical machinery with bearing, automobile, railway and other transportation industry with bearings, engineering machinery bearings. Nc equipment bearing the pace of development in these areas should be accelerated, to constantly improve the level of our country bearing manufacturing and research and development speed, thereby improving the technical level and precision of bearing, shorten the production cycle of bearing, reduce costs, expand the export of bearing, the numerical control equipment will play a very important role.
In bearing manufacture process, bearing retainer plate stamping die and extrusion die of plastic cage, all kinds of stamping mould, needle roller bearings with a drawn cup high precision mold, the bearing ring cold rolling mold and the forging die and bearing assembly mould processing and manufacturing, need to be efficient, high precision mould numerical control equipment. Because domestic nc equipment cannot meet its function and accuracy of bearing industry part of high precision mould numerical control equipment are imported, part with homemade equipment or modification to solve, domestic equipment has huge demand, but the share is low.
Bearing products specialized production determines the special numerical control production according to the characteristics of the product development of short-term. High precision, low noise, large quantity and low cost is the key to the production of motor bearings. The current domestic production of the 300 or so of deep groove ball bearing grinding automatic production line, numerical control technology has greatly increased the low noise motor manufacturing level; Automatic grinding production line is made by the miniature, small bearing automatic production line to the automatic production line of large bearing extension. The requirement for numerical control technology is becoming more and more diversified, also more and more difficult. Active measurement technology in automatic production line, automatic closed detection technology, error compensation technology, automatic monitoring, numerical control manufacturing quality timely transmission and quality analysis techniques such as process control methods.
Bearing assembly (including bearing product packaging automatic detection, automatic) the problem of automatic line has been plagued by technical progress. Famous bearing company abroad, the technology has actually applied successfully for many years. Rely on imported and domestic, and use effect is still not satisfactory. Thus developed bearing assembly automatic production line, and with the bearing grinding automatic production line of organic connection, for increasing production efficiency and product quality of bearing, reduce the number of process flow of bearing parts, reduce the influence of human intervention, to reduce the cost, the significance is significant. As many varieties of bearing, different varieties, automatic assembly line has different features, thus bearing industry of bearing assembly of the diversity of the numerical control equipment requirements are put forward.
