推拉窗铝合金型材热挤压模设计毕业论文设计.docVIP

推拉窗铝合金型材热挤压模设计 模具工业在美国被认为是“工业的基石”，在日本更被推崇到“进入富裕社会的原始动力”，在我国，国务院通过的《装备制造业调整和振兴计划》中也把模具及其制造的装备的技术水平作为重点内容。模具由于其具有工序少、材料利用率高、低耗能、易生产等特点，在汽车、能源、机械、电子、信息、航空航天工业和日常生活中被广泛应用。 本次设计的型材属于典型的民用建筑空心型材，采用平面分流组合模，根据型材断面积和外接圆直径选取16.3MN挤压机，确定挤压筒挤压轴挤压垫模心、模孔等工模具的尺寸，然后通过强度校核和实际分析，得到合理可用的工模具。 通过对铝合金推拉窗热挤压模具的设计，对模具的结构以及设计过程有了初步的认识。这次毕业设计是理论与实践的又一次结合，锻炼了设计者对参考文献的查阅能力、独立思考能力和创新能力。 Sliding 88822 aluminum alloy hot extrusion die design Abstract Mold industry in the United States is considered to be the cornerstone of industry, in Japan even been respected to the raw power into the affluent society, in China, the State Council passed the equipment manufacturing restructuring and revitalization plan, also the mold and manufacturing the technical level of equipment as the main focus. Because of its small mold processes, material utilization, low energy consumption, easy to produce, etc., in the automotive, energy, machinery, electronics, information, aerospace industry and are widely used in daily life. The design of the profile is typical of civil hollow profiles, using the plane porthole die, according to the profiles basal area 551m2 and circumcircle diameter 115mm Select 16.3MN extruder, extrusion cylinder diameter is determined 140mm. Extrusion axis length 1020mm, diameter size 136mm. Extruded solid selection pad diameter is 139mm, thickness 50mm. Calculate the mold core, mold tooling holes and other dimensions, and then through the strength check and the actual analysis, reasonably available tooling. By hot extrusion aluminum sliding mold design, mold structure and the design process have a preliminary understanding. The graduation project is yet another combination of theory and practice, exercise designers references inspection, independent thinking and innovative ability.
