在金属切削机床或其他机械制造叶中,很多防护罩壳与箱体另件大都是用金属薄板材料制造。而目前市上所售的薄板常发现有挠曲现象,故在裁剪前必需用人工敲平。这样不仅工作量很大,并且工作时发出强烈噪音,因此改用机械锻压来代替人工敲打是当前冷锻工作的重要方向。 如一件弯曲的 In metal cutting machine tools or other machinery manufacturing leaves, many protective covers and box parts are mostly made of sheet metal material. At present, the plate on the market often found flexing phenomenon, it must be manually trimmed before cutting. This is not only heavy workload, and make a strong noise at work, so the use of mechanical forging instead of manual beating is an important direction for the current cold forging work. As a curved
