Innovative development of high-quality large-scale automotive high-end automotive stamping dies

Low-end automotive stamping dies often rely on the manual techniques of the fitter. Combined with the development of modern CNC machining technology, high-end automotive stamping die manufacturing enterprises must configure large-scale gantry five-face machining center, large-scale gantry five-axis machining center, large-scale gantry three-coordinate measuring equipment and advanced online measuring system. Develop high-end automotive mold manufacturing technology, focusing on the surface parts of automotive stamping parts covering automobile engines, chassis, and steel plate shaped bodies that make up the cab and body (such as engine covers, front and rear panels, radiator covers, water tank covers, and doors) Inner and outer panels, side panels, roofs, front and rear beams, trunks, chassis, etc., because the mold structure of these parts is more difficult, the size is larger, and the quality requirements are particularly high. The manufacture of these molds can only be achieved by the large-stroke, high-precision processing equipment and the support of large-stroke advanced testing equipment, so that the quality, schedule and cost of the mold can be recognized by the market. The processing machine tool stroke generally requires 4m on the X axis, 3m on the Y axis, and 1m on the Z axis. For this large-scale high-end automotive cover mold, large-scale gantry numerical control equipment and large-scale gantry coordinate measuring equipment are required.

Large CNC equipment required for large-scale automotive panel mold manufacturing, especially large-scale gantry five-axis linkage equipment, currently more than 70% need to rely on imports. Innovative development of high-quality large-scale high-end molds, it is necessary to develop the development capability of CNC machining equipment and testing equipment, focusing on the research and development of 4-5m dynamic beam type super heavy-duty gantry machining center, large-scale three-coordinate, five-axis linkage CNC gantry machining center, And pay special attention to the research and development of key core components of CNC machine tools , such as high-speed precision electric spindle, tool magazine robot, CNC rotary table, high-speed protection device, CNC power tool holder and double swing angle milling head. At the same time, we must pay attention to the research and development of CNC machine tools .
