针对等厚圆弧板叶片成形模具加工难度大、费用高的问题,提出了将上模、下模的制作采用分层加工和整体加工相结合的办法,只需普通的加工设备就能完成模具复杂的自由曲面的加工,降低了模具的加工难度和加工费用。现场生产实践证明,用这种模具通过冷压成形的叶片,其几何尺寸符合图纸要求,通风机的整机性能能够达到设计要求。该方法具有加工范围广、加工成本低的特点,具有良好的应用前景。
In view of the difficulty of high-arc-shaped blade forming mold processing, high cost, put forward the upper mold, the lower mold production by the integration of processing and the overall processing methods, only ordinary processing equipment to complete the mold Complex free-form surface processing, reducing the mold processing difficulty and processing costs. Field production practice has proved that with this type of mold by cold forming the blades, the geometric dimensions in line with the drawings requirements, the overall performance of the fan to meet the design requirements. The method has the advantages of wide processing range, low processing cost and good application prospect.
