The invention discloses a
cutting-stirring
friction welding composite
processing device for a floating double-shaft-shoulder double-stirring needle and a manufacture method thereof, and particularly relates to a combined or composite
processing device capable of simultaneously carrying out milling or
cutting processing and stirring
friction welding processing and a method thereof. The
cutting-stirring
friction welding composite processing device for the floating double-shaft-shoulder double-stirring needle integrates a cutting
system or a milling
system, a stirring friction
welding system, a forced cooling system, a
gas protection system, a
temperature sensing system, a pressure
induction system, a milling liquid supply system and a sensing-
free system. The cutting-stirring friction
welding composite processing device has functions of
temperature control,
gas protection,
pressure detection, cooling liquid protection, milling head replacing and floating double-shaft-shoulder self-supporting stirring friction
welding. The method for carrying out cutting-stirring friction welding composite processing on workpieces can meet strength requirements of mechanical processing of
ferrous light metal materials,
carbon steel materials and
alloy steel materials. The cutting-stirring friction welding composite processing device for a floating double-shaft-shoulder double-stirring needle and the manufacture method of the cutting-stirring friction welding composite processing device reduce manufacture procedures, save
processing cost, have the advantages of being high in efficiency, excellent in quality, high in stability and saving in energy, break through limitation of conventional
machining technology, form a new method and a new thought for machinery processing, and have wide application prospects in industries of heating, air conditioners, ice manufacture, freshness keeping,
medicine preparation, construction, aquatic products and foods.
