我们在生产中使用规格为31×31×1.75毫米和27×27×1.75毫米的 A3F国产冷拉薄壁方管。过去下料采用砂轮锯切割方法,污染严重,噪音大,有害于工人身体健康。大量生产时片砂轮消耗量大,不仅成本高,而且操作很不安全。为了改变这种落后生产状况,我们根据冲切圆管的原理,设计制造了方管冲切模具,它实现了以冲代锯。经生产使用,效果较好。

We use A3F domestic cold-drawn thin walled square tubes in production sizes 31 × 31 × 1.75 mm and 27 × 27 × 1.75 mm. Past the use of cutting sawing cutting, serious pollution, noisy, harmful to the health of workers. Large-scale production of whetstone consumption, not only high cost, and the operation is not safe. In order to change this backward production conditions, according to the principle of punching pipe, we designed and manufactured a square pipe punching die, which realized the punching and sawing. After production, the effect is better.
