Description

Volume weldering cylindrical member Opposite roller spinning processing method
Technical field
The present invention relates to spinning manufacturing, after specifically adopting volume soldering method to process cylindrical member, utilize self-made tooling to carry out Opposite roller spinning processing, shaping coupling barrel structural member.
Background technology
Along with developing rapidly of China's Aeronautics and Astronautics technology and national economy, also more and more, more and more urgent to the demand of thin-wall tube-shaped element, such as certain cylindrical member parts:
Part material is 3A21 aluminium alloy, closed tubular construction, has that overall size is large, wall thickness is thin, yielding, the high processing difficult problem of required precision.
Through investigation, on market, three sets of plan are mainly taked in the processing of similar structures part: 1, forging machine adds, and 2, the weldering of plate volume, 3, cylindrical member blank spinning, above-mentioned three kinds of schemes exist that following some is not enough:
1, forging machine is adopted to add, required forging ' s block dimension is greater than 40kg, final products 4.0kg, stock utilization is only 10%, rough turn, need to carry out repeatedly timeliness between half finish turning, finish turning and remove residual stress, need repeatedly to be installed centering, it is very large that the easy texturing machine of thin-walled parts adds difficulty, artificial and development cost is very high.
2, plate volume is adopted to be welded into shape, use 3A21 aluminium sheet as raw material, in volume weldering process, circularity, the linearity equidimension of cylindrical member require higher, cannot obtain Reliable guarantee, simultaneously owing to there is longitudinal seam, the performance of cylindrical member reduces, this cylindrical member working environment is HTHP, there is larger potential safety hazard.In volume weldering processing, need to increase the operations such as flaw detection, annealing, mechanical grinding weld seam, add manufacturing cost.
3, cylindrical member blank mould pressing; need to make many cover cores and other matching tooling; considerably increase the cost (accounting for 10% ~ 20% of totle drilling cost) of core production and administration, because the inner surface of workpiece slides along core while by spinning roller pressure, its precision is ensured by spinning mandrel; the inner surface geometric accuracy of product is poor; small lot single-piece production, mould pressing does not have advantage, and labour intensity is very large; production efficiency is low, and cost is very high.
MT (MAN Technologie) joint-stock company of Germany proposes Opposite roller spinning principle the earliest, and has carried out system research.Within 1991, the said firm entrusts the Di Sen mechanical engineering company being positioned at Dortmund, Germany to be responsible for having built European maximum vertical structure Opposite roller spinning machine, has been successfully applied in the manufacture of European Space Agency's Ariane 5 rocket booster housing.The domestic correlative study not having Opposite roller spinning, and all adopt above-mentioned three kinds of techniques to process for the processing of cylindrical member.
Summary of the invention
Low for overcoming the machining accuracy existed in prior art, the deficiency that cost is high, the present invention proposes a kind of volume weldering cylindrical member Opposite roller spinning processing method.
Detailed process of the present invention is:
