一、前言目前我国生产的钢筋调直切断机定长料架,一直是生产厂家研究的课题。国内外定长料架大体分为三种形式,一是机械式,二是电磁铁式,三是电脑程序控制式。机械控制式大都是我国50年代产品,钢筋在两角钢之间运行,不易观察调直质量,不易调试,使用不便以及易出短头浪费钢筋;近代的电脑控制式虽然较为理想,但生产成本高,工地维修困难,不易采用。现在国内生产的电磁铁控制料架虽较为理想,但长度一般只为
I. INTRODUCTION At present, China’s production of steel bar straightening and cutting machines has been the subject of research by manufacturers. There are three types of fixed-length racks at home and abroad, one is mechanical, the other is electromagnet, and the third is computer program control. Most of the mechanical control type products are made in China in the 1950s. The steel bars run between the two angles. It is not easy to observe the straightening quality, it is not easy to debug, it is inconvenient to use and it is easy to waste short heads. The modern computer control type is ideal, but it has high production costs. The construction site is difficult to maintain and is not easy to use. Although domestic electromagnet control racks are ideal, the length is generally only
