斜轧新工艺生产某些简单零件毛坯,如钢球、滚子等国内外均有先例。但轧制尾杆这类形状复杂(由六个面转体组成)、大尺寸(最大直径100毫米、长度202毫米)、大断面收缩率(83％)及细长比大(4.8)的产品,在国内是没有的,在国外资料检索中也未见到。 为研究该工艺,先后解决了中心疏松、产品扭转、堆积轧制、轧辊曲线设计、特殊导板与轧机的设计、复杂孔型的加工、调整工艺和加热冷却工艺等一系列难题,轧出了完全合格的产品。产品的机械、金相等性能、靶场考核等均满足要求。 斜轧与原平锻机比生产尾杆优点为:1>单机生产效率提高5倍多;2>产品成本下降
Slanting new technology to produce some simple parts rough, such as steel balls, rollers and other domestic and foreign precedents. However, such products as the complex shape of the rolling tail (consisting of six face rotors), large size (maximum diameter 100 mm, length 202 mm), large reduction of area (83%) and slenderness ratio , There is no in the country, have not seen in the foreign data retrieval. In order to study this technology, we have solved a series of problems such as center looseness, product reverse, pile rolling, roll curve design, special guide plate and mill design, complex hole processing, adjustment process and heating and cooling process, rolling out completely qualified products. Products of machinery, gold performance, shooting range, etc. to meet the requirements. Slant rolling and the original forging machine than the production of tail rod advantages: 1> stand-alone production efficiency increased more than 5 times; 2> product cost decline
