针对某公司对方管下料的特殊要求,设计了一台新型的多头锯组合装置,通过两次装夹定位,实现8个切口的高效高质量加工。论文分析计算了其运动参数和动力参数,经现场加工证实,该装置可满足对45°多切口的锯切。本文对方管切割方式进行了规划设计,不仅满足了产品的加工精度,提高了生产效率,还使产品具有了明显的比较优势。 Aiming at the special requirements of the tube feeding of a certain company, a new multi-head saw assembly was designed. With two clamping positions, eight cutting edges were achieved with high efficiency and high quality. The paper analyzes and calculates its kinematic parameters and dynamic parameters. It is confirmed by on-site processing that the device can meet the requirements of 45 ° multi-notch sawing. In this paper, the square tube cutting mode has been planned and designed, which not only meets the processing precision of the products and improves the production efficiency, but also makes the products have obvious comparative advantages.
