Description
Technical field
The present invention relates to spinning manufacturing, specifically adopt volume soldering method to process after cylindrical member, utilize self-made tooling to carry out wheel rotary pressing processing, shaping cylindrical member spinning 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, for example certain cylindrical member parts:
Part material is 3A21 aluminium alloy, and the tubular construction of sealing has that overall size is large, a wall thickness, 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, plate volume weldering, 3, cylindrical member blank spinning, above-mentioned three kinds of schemes exist that following some is not enough:
1, adopt forging machine to add, required forging ' s block dimension is greater than 40kg, final products 4.0kg, stock utilization is only 10%, between rough turn, half finish turning, finish turning, need to carry out repeatedly timeliness and remove residual stress, the centering that need to repeatedly be installed, it is very large that the easy texturing machine of thin-walled parts adds difficulty, artificial and development cost is very high.
2, adopt plate volume to be welded into shape, use 3A21 aluminium sheet as raw material, in volume weldering process, circularity, the linearity equidimension of cylindrical member are had relatively high expectations, cannot obtain Reliable guarantee, simultaneously owing to there being longitudinal seam, the performance of cylindrical member reduces, this cylindrical member working environment is HTHP, has larger potential safety hazard.In volume weldering processing, need to increase the operations such as flaw detection, annealing, mechanical grinding weld seam, increased manufacturing cost.
3, cylindrical member blank mould pressing; need to make many cover cores and other matching tooling; the cost (account for totle drilling cost 10%～20%) that has greatly increased core production and administration, because the inner surface of workpiece slides along core when being subject to spinning roller pressure, its precision is guaranteed 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.
