我厂是生产汽车电器的工厂,在小型机械和电器零件制造中大量使用截面为各种形状的成卷材料,卷材在加工成零件前必须校直。园形材料的校直较好解决,而截面形状为非园(如三角、四方等)的连续校直则较困难,我厂长期使用手锤,既影响质量,生产工艺又落后。 Our factory is a factory producing automobile electrical appliances. We use a large amount of roll materials of various shapes in the manufacture of small machinery and electrical parts. The coils must be straightened before being machined into parts. The alignment of the garden material is better solved, and the continuous alignment of the non-circular section (such as triangle, square, etc.) is more difficult. The long-term use of hand hammer in our factory not only affects the quality but also lags behind the production process.
