【摘要】 射孔技术是石油开采工程中的关键技术之一。射孔弹在石油工业中有着广泛和大量应用,其性能优劣对石油产能影响极大,然而射孔弹的质量及可靠性除与其正确的设计、所用材料质量、生产工艺及生产过程中工艺参数的控制密切相关外,还有一个重要的影响因素——药型罩。药型罩是射孔弹的“刀刃”、是影响石油生产的关键因素之一。目前,由于多数药型罩生产厂家都是采用老式油压机,生产自动化程度很低,液压系统的整体精度靠手动调整压力继电器和手动溢流阀的匹配关系保证,调整困难,受器件、压力显示精度和人为因素的影响,很难保证同一压制压力下,调整后和未调整前压制结果的一致性。虽然很多厂家从改变药型罩粉末配方等方面做出了许多研究,但是很少从药型罩生产设备入手来提高药型罩生产效率和提高药型罩生产过程中的自动化程度。针对现行药型罩生产厂家的生产设备,本文对提高药型罩自动化生产程度的旋压设备进行了结构设计,其主要工作包括:(1)根据金属粉末的流动性,设计了以刮板法为基本原理、以1s内快速稳定、称量精度为0.02g的高精度电子称作为称量工具的称量系统。(2)结合现有的金属旋压成形技术和粉末成形技术,设计了会属粉末旋压成形的旋压系统,在原有模具基础上加以改进,设计一套适合旋转压制的主轴系统,并进行了强度校核。(3)为避免药型罩在检测过程中容易划伤、提高药型罩壁厚差检测精度,设计基于激光位移传感器的非接触自动检测系统,激光传感器的检测精度达到2μm,超过了手工检测的0.04mm的要求。(4)为提高设备生产的自动化程度,设计了进行自动上料和下料的机械手。(5)设计了保证设备的正常运行的液压和控制系统。本论文结合厂家提供的药型罩生产工艺,设计了一套完整的金属粉末药型罩旋压设备,提高了药型罩生产效率和压制压力的控制精度。更多还原

【Abstract】 The perforating is one of the key technologies in petroleum engineering. Perforating charge is extensively applied in petroleum engineering. It’s quality directly affects petroleum productivity. However, it is vital important to guarantee perforating charge quality and to enhance the credibility. The quality and credibility of perforating charge not only relate with the right design、the material quantity、producing process and controlling process parameters of perforating charge, but also have close relation with another important factor, its the liner. Liner is the knife edge of the perforating charge. It is one of the most important key parties. There are lots of manufacturer produce the liner by the old press machine with low level automation, the Precision of hydraulic system guaranteed through manual operating the pressure relay and relief valve. It’s difficulty to make sure the result consistent with adjusting. Although they do lots of research in improve the metal power, but they never do research to improve the efficiency and the level automation.According to the equipment of the manufacturer, this paper researches mainly includes the following aspects:(1) According to the fluidness of metal power, designing the scraper blade, and using the electronic balance (soon responded in 1s、Measuring Accuracy at 0.02g) as the tool for the weighing system.(2) According to the metal rotary pressured technology and the Powder molding technology, design the metal power rotary pressed system. Improving the old mold and designing a shaft system for rotary press, and Strength check is finished.(3) Because the old measure method will scratch the outside of the liner, the non-contact laser measurement system is designed, which improved the precision.(4) The Manipulator for translation the material and the product is designed for high level automation.(5) Hydraulic system and the control system are designed.更多还原
