Yangzhou HENGRUN auto parts factory is located in Yangzhou Jiangdu Economic Development Zone, where well-developed transportation, Nanjing high-speed Beijing-Shanghai high-speed runs through the whole territory. Our factory is a professional auto cover, auto mold, automotive sheet metal and forgings manufacturer, with professional and technical personnel, excellent processing equipment, rich production experience, advanced production technology, improve the detection means. Existing VMM-1000 machining center, 4021 milling machine, three-dimensional coordinate measuring instrument, such as mold production testing equipment and Stamping production line and three-dimensional plasma cutting machine 2, has formed an annual production cover 200,000, auto mold 350 sets capacity. For a long time, high-quality products, reasonable prices, excellent service for our plant has won widespread praise in the market's favor and society. Now for Higer Bus, Shandong Automotive Group, JAC bus, Kowloon Motor Bus and other long-term customer support. I plant to internal management, has passed the ISO9001: 2000 quality system certification. Enterprises to pursue product fine, zero defect as the goal, to ensure the stability of product quality to meet all reasonable requests of customers. I plant the spirit of "honesty, truth-seeking, innovative" business philosophy, and constantly improve, forge ahead with the times. Common development with customers to create a better tomorrow! Automotive panel die structure design features a large size. Apart from the cover itself is relatively large outside, the cover positioning the die parts, the mounting structure of the mold, the upper and lower mold guide, a mold lifting, inverting and transport devices, etc. should be increased structure size of the die. Basic parts of the frame structure. Automotive panel die structure size larger. To reduce weight and improve the manufacturing process of the mold, generally are designed by two plate-shaped member having two levels, separated by vertical bars connected to the frame structure. Generally die basic parts (die holder) for selection of a standardized multi-solid sheet. 3 low degree of standardization. Degree of standardization and standard selection of content is generally die design cover much larger than the die. For example, the average full selection of punching die can be assembled from standard parts, and automotive panel die at least its basic parts are non-targets. 4 mold material quality requirements are relatively low. For the life of cover 400,000 times less drawing die working parts (punch, die, blank holder) material, commonly used high strength cast iron that can be. The general working parts are mostly die tool steel. Five die manufacturing auto cover Features an auto cover die basic parts and work preparation is the key part of the rough production preparation. They are mostly single-piece casting and production, manufacture casting model is the key blanks prepared. Usually used solid casting (the disappearance of one type) 2 due to the large automotive panel die outline dimensions, so it needs to process large machining equipment. Commonly used are: goal planer, milling machine, floor boring and milling machine, CNC gantry milling machines, multi-axis CNC milling machine and so on. In addition, in order to debug the mold, but also require large presses and research co-tryout presses. 3 auto cover die manufacturing process is focused on processing the working parts of the feature. Because it is a combination of three-dimensional curved surface composition, so processing difficulties, difficult to ensure accuracy. Improve the accuracy of CNC machining is the key to improving the precision mold and shorten the manufacturing cycle. 4 die assembly cover research together and adjust the pressure test is extremely important to the process of the manufacturing process. In particular pressure test the entire design and manufacturing work to adjust the proportion of large proportion. With advances in technology, to improve machining accuracy and research co-debug cycle will gradually shortened. 5 a cover generally require two or more die, and die manufacturing order of each set is constrained by the need to process validation. Conventional manufacturing order is the first manufacturing drawing die, and then followed by all kinds of forming die, die repair.
