Abstract

The manufacturing method of the CNC milling and processing support mold is characterized in that: a high-strength hard metal that can be rapidly formed at room temperature or at a medium temperature below 70°C, has a density of 0.15-0.45g / cm3, and a compressive strength of 2.3-3.5Mpa Use high-strength foam plastics as raw materials, add a certain proportion of quartz sand to the rigid foam plastics, the particle size of the quartz sand is not greater than 100 mesh, and the addition ratio is within 5-20%, mix high-strength rigid foam plastics and quartz sand, Bubble, and then cast in the processed recessed pit coated with lubricating oil or release agent as a release coating, and make it fill the pit, level it and use it as a clamping support surface for the other side of the next step of processing.

Description

Manufacturing method of support mold for CNC milling processing Technical field [0001] The present invention is a manufacturing method of a numerically controlled milling support mold capable of rapid prototyping on site. Background technique Numerically controlled forming thin-walled parts, especially aviation numerically controlled machining parts, mostly are beams, ribs, Frames, webs and other parts are basically in the shape of "I" from their cross-section. During the forming process of such parts, the flat plate is generally clamped. On the milling machine, one of the sides is first milled according to the requirements, and then the machined side is flipped and clamped, and then the other side is milled and processed. one side. Due to the fact that there will be many depressions in the shape of the part during processing, when one side of the processing is completed and the clamping is turned over, Difficulties will arise. This is because the wall thickness of t...
