10:05a	requested the mold processing equipment These features combined, thus causing the car dies very difficult process. Shi-ping told reporters: "The car would die at the design stage to consider all of the precision problem, the process is to ensure that the process of implementation of various requirements. Can not be processed after completion, but also a great number of changes and follow-up process to complete, so not only can not guarantee the quality, processing cycle will be severely stretched. "In addition to high speed machining, the mold is another feature of super-hard process. Because of the hardness of the mold surface requirements are very high, if done quenched after finishing it, will cause thermal deformation of the mold, the mold can not guarantee accuracy. comforter sets In order to achieve both high hardness and also parts of high precision, are often introduced after quenching process. Shi-ping, a car in the process of mold it is necessary to achieve a large size, high speed, but also to achieve high precision, but also to achieve super hard working (hardness can reach HRC60 or more), thus causing the car very difficult to mold . For complex and multi-functional composite mold cavity, with the workpiece shape of the complex, also need to improve the mold design and manufacturing standards, a variety of grooves, a variety of materials in a mold formed or assembled into a multi-component functional composite mold, require leaning programming stage of processing the deepening processing to achieve, to improve the processing technology for high-deep cavity cutting ability and improve their comprehensive stability. "Domestic automobile users to request for the car dies, the first is the low cost, because the development cost in automotive manufacturing, die absolute bulk. bed in a bag Now the car more and more varieties and new vehicle development and reduce development costs are often the key to the success of a new car. " Shi-ping, said, "As China's automotive vehicle production in a single species gradually increased, so long life for the car dies, it is increasingly high demand. "With the increased vehicle production, stamping equipment performance improvements, efficiency in pursuit of stamping, punching a speed faster and faster, which requires die in the heat distortion, high accuracy, stability and other aspects of the performance is better. bed sets The higher accuracy of auto mold, the better the stability, the more long life. With the auto manufacturing mold levels and more mature, China's automobile mold has been able to successfully resolve customer demand for these hard and has reached the world level. Large demand for automotive mold processing center with high speed and high finishing car mold to a higher level of processing equipment and higher requirements. Forming part of the increasingly large scale, improve press productivity requires a multi-cavity mold, automobile mold large tonnage weighed 50 ~ 70t, which requires mold processing equipment must be greater than ever table, large Y-axis and Z axis travel, but also a large load, high rigidity, high consistency.bed in a bag sets With the mold steel hardness, also requested the mold processing equipment, heat-stable, high reliability. The refinement of mold compound to processing equipment, high efficiency even more concern. Machinability of high-speed milling with hard materials, processing and smooth, cutting force is small, the workpiece temperature deformation of small businesses and many other advantages to make the mold growing importance of high-speed processing. "For the car dies, the main processing equipment is the gantry processing center, part of which is the axis or five-side processing, surface processing, relatively speaking the application of the five most widely used, but regardless of what equipment should meet car mold high speed, super-hard, high-precision, high rigidity and other processing characteristics.designer comforters (Comment on this)
10:06a	become the most commonly used high-precision processing technology "The primary objective of automobile die industry is import substitution, to achieve localization of automobile molds. "But as more Chinese joint venture auto company, so that many still rely on imported car mold, mold can only serve the domestic auto ancillary and supporting role. In recent years, Chinese auto mold made significant headway in the world who have - come from behind, has become a great power die. However, export volume of China's automobile mold, little, it shows we are far less automobile mold plastic mold export development so fast. comforter sets "China's auto exports less the main reason for mold or mold because the car is relatively high technical threshold. "In the ordinary world seems flat, before the car dies in the course of development, the access threshold for foreign customers, the domestic automobile mold project management, design technical weakness, lack of practical production experience, international marketing capability all aspects of poor restricting the development of Chinese automobile mold faster. But overall, China's car dies very fast pace of growth. "China has basically all the cars can produce mold, not the lack of equipment and technology, but rather mature with experience in high-end talent.bed in a bag It can be said now, we and Germany, Japan and other developed countries, not much different than automobile mold, the main difference is not technology but management and experience. "World peace, as often mentioned, in addition to the special high-end cars now is not the actual design and manufacture of mold inspection, China are all working to achieve localization of automobile molds, but also began to expand the export share of the mold. Large-scale, complex development trend of automotive mold automotive panel die mold in particular are all large and medium sized molds, large scale is a major feature of automobile mold, the weight of a single set of model on up to four 50 tons, is also a small die to tons for the weight units. bed sets "Like a car door panels are a standard mold before, and now widely adopted as a whole Side technology, the result table press tonnage and the growing line of other smaller workpieces may also be two or more parts combination in a mold, which caused the car key to mold larger and complex. "Shi-Ping, said. "In addition to large-scale, auto mold and a process characterized by the main free-form surface machining, which requires the dynamic accuracy of machine tools is very high, and in order to reduce processing residue and to ensure processing efficiency, small space, high-speed, become the most commonly used high-precision processing technology.bed in a bag sets "According to Shi-Ping,, when the car dies after large scale, will bring Henduo new Wenti, geometric dimensions Da, Jing Du Kaoji Chuang precision machining is very difficult to ensure, for example: The original did not notice De diurnal temperature changes, Xianzai will seriously affect the precision mold processing. Temperature difference between day and night in the north often 10 , this contraction and expansion of mold temperature to bring the amount is enough to match the upper and lower tolerance model. Therefore, for large mold shop in general need to adopt constant temperature. Another characteristic of large automobile mold cavity is more complex, so the depth of processing, the vertical degree of flatness and other requirements are high, machine tools and props for the high-rigidity, high accuracy, high dynamic static and other requirements are also high.designer comforters (Comment on this)
