12000 Tons Tension Tensile Machine Of Aviation Grade Aluminum Alloy Plate

The high performance of aluminum alloy material with high strength and high tenacity is widely used in modern aviation, ships, weapons and equipment, and other fields, with the rising of manufacturing level and the increasingly development of economy, the big cross section, high quality aluminum alloy plate speed growth in market demand.Therefore, the development capacity of aluminum alloy plate tension machine, produce meet aerospace, national defense and national economic development demand of aluminium and aluminium alloy thick plate, is at present our country mechanical industry and equipment manufacturing industry and aluminum processing urgent tasks.In this paper, the development and production of 12000 tons of aluminum alloy plate tension machine as the center, the mastery of the aviation aluminum alloy plate tension machine equipped with the key and core technology; Formed a ton aluminum alloy plate tension machine equipment series product development and supply ability,drive the production of high quality air aluminum sheets.For multiple sets of jaw how to realize the synchronization and the problem of uniform clamping, the technique of composite cant clamping jaw, a synchronous clamp after additional secondary clamping alone, solves the uneven size of large width,thickness of aluminum plate clamping evenly and reliability issues.Based on the research of the stretching process control model, uses the method of combining the theoretical research and experiment, gained a plank pre-draft process,make the plate after the pre-tension its internal residual stress is reduced to a greatextent.Through on-line monitoring preloaded bolt pre-tightening force in the process of installation, after repeated adjustment, finally fixed chuck chuck and activities all actual load preloaded bolt pre-tightening force reached around 2300 T, difference control within the 50 T, has reached the design requirements.
