空气钻头是地震勘探钻井的重要钻具。近年来,新疆石油管理局地调处对这种钻头的需求量在逐渐增加。但因刮刀片(见图1)过去是锻制扁方条(24×62×330毫米,3件)后,全部机械加工成型(需要23道机加工工序),这样,大大降低了空气钻头的质量和产量。为了适应地震勘探发展的需要,我们改进了刮刀片的锻造方法,采用胎模黑皮锻造,效果良好。 Air drills are important drilling tools for seismic exploration drilling. In recent years, Xinjiang Bureau of Petroleum Administration of the adjustment of such drill bit demand is gradually increasing. However, since the scraper blade (see Figure 1) used to be forged square bar (24 × 62 × 330 mm, 3 pieces), all the machining molding (requires 23 machining processes), thus greatly reducing the air drill Quality and yield. In order to meet the needs of the development of seismic exploration, we improved forging scraper blade method, the use of black die forging die, with good results.
