【摘要】：金属挤压加工是金属压力加工的主要成形工艺之一,适用于多种金属及其合金的挤压生产,是型材、管材和线材的主要加工方法,其产品在建筑、航空、交通、通信等领域有着广泛的应用。因此,挤压加工技术在国民经济中占有极其重要的地位。挤压机是挤压加工的主要装备,缸梁一体式液压机是液压缸与主横梁合二为一的新型压力机,它结构紧凑、质量小、制造成本较低、便于运输,特别适合于千吨以上压力机的制造与应用。本课题的主要任务是对30MN缸梁一体式液压挤压机相关参数进行理论计算,完成本体结构设计,并对其进行有限元分析校核。论文基于液压机的设计理论,参考已有液压挤压机结构和设计经验,提出了30MN缸梁一体式卧式液压挤压机的基本设计方案。对挤压机的本体结构进行了设计,对主工作缸、主回程缸、穿孔缸等相关参数进行了设计与计算。采用MARC软件对缸梁一体式主工作缸进行了有限元分析,对主工作缸工作过程中的各向应力、应变和位移等参数进行了分析,各性能参数满足相关设计要求,并采用Pro/E软件对挤压机进行了三维建模,对挤压机的工作过程进行了仿真。本文所设计的30MN缸梁一体式液压挤压机可为紧凑型大型吨位挤压机设计提供一定的参考。
[Abstract]:Metal extrusion is one of the main forming processes of metal pressure processing. It is suitable for extrusion production of many kinds of metals and its alloys. It is the main processing method of profile, pipe and wire, and its products are used in construction, aviation and transportation. Communication and other fields have a wide range of applications. Therefore, extrusion processing technology plays an extremely important role in the national economy. Extrusion press is the main equipment for extrusion processing. The cylinder beam hydraulic press is a new type of press which combines the hydraulic cylinder and the main beam. It has compact structure, small quality, low manufacturing cost and easy transportation. It is especially suitable for the manufacture and application of the press over 1000 tons. The main task of this paper is to calculate the related parameters of 30MN cylinder beam hydraulic extruder, complete the design of body structure, and carry out finite element analysis and verification. Based on the design theory of hydraulic press and referring to the structure and design experience of hydraulic extruder, this paper puts forward the basic design scheme of 30MN cylinder beam horizontal hydraulic extruder. The main working cylinder, main return cylinder and perforated cylinder are designed and calculated. The finite element analysis of the integral cylinder of cylinder beam is carried out by using MARC software. The parameters of stress, strain and displacement in the working process of the main cylinder are analyzed, and the performance parameters meet the relevant design requirements. The three-dimensional model of the extruder was built by Pro/E software, and the working process of the extruder was simulated. The 30MN cylinder beam hydraulic extruder designed in this paper can provide some reference for the design of compact large tonnage extruder.
