Abstract
The utility model relates to a combined type friction stir welding stirring head aiming at plates different in thickness. The combined type friction stir welding stirring head is characterized in that a center matrix is inserted in a sleeve coaxially; a threaded connecting column and a threaded connecting hole are respectively provided with an inner thread and an outer thread which are matched with each other; by the threaded matching of the threaded connecting column with the threaded connecting hole, the shaft shoulder of the center matrix is connected with a sleeve clamping body; and a matrix stirring pin is connected with a sleeve stirring pin coaxially. During processing, the center matrix is universal, only a series of sleeves with different size parameters need to be processed, without the processing of multiple whole stirring heads, therefore, processing materials are saved. If the stirring head is abraded during processing, only the sleeve needs to be replaced and the center matrix still can be used. The time for assembling and disassembling the stirring head is saved and the welding efficiency is improved. Simultaneously, the center matrix and the sleeve can be selected from dissimilar materials so as to be suitable for the welding of various materials.
Description
Technical field
The present invention relates to a kind of combined type stirring friction welding agitator head, relate to the Solid-phase welding technical field, relate in particular to a kind of design that is directed against the combined type stirring-head of the different thicknesss of slab of friction stir welding to different-thickness sheet material.
Background technology
Friction stir welding (FSW) is a kind of new solid-state interconnection technique, has that weldquality is good, a heat affected area residual stress and residual deformation is little, the low advantages such as (less than the mother metal fusing points) of welding temperature.Friction stir welding method has obtained worldwide patent protection (WO93110935).FSW technology relies on rotates stirring-head and the frictional heat that two weldment contact-making surfaces produce at a high speed, makes the seam crossing metal produce the plasticity softened zone, wherein rotate stirring-head around plasticity softened zone metal receive stirrings, extruding, mobile with the formation plastic metal.
Stirring-head is the rotating soldering appliance of a kind of on-consumable of adopting of friction stir welding, and it mainly contains the shaft shoulder and mixing needle is formed.In welding process, stirring-head has and effects such as its material around frictional heat, broken workpiece surface oxide layer, transfer plastic flow material.Therefore; Stirring-head is the core of agitating friction welding technology; Whether rationally its structural design directly affects the flowing of generation, plastic metal of frictional heat source; Determined the mechanical performance of friction stir welding, can the decisive influence effect have been arranged application in a wider context for friction stir welding.
In welding process; Need overcome very big resistance when stirring-head and workpiece relative motion,, and use more stirring-head to be mostly integral structure at present so the wearing and tearing of stirring-head are more serious; Need after the wearing and tearing whole stirring-head is changed, cause the waste of material and the increase of production cost.And the stirring-head of integral type need repeatedly remove and install when sheet material different-thickness or different materials is welded, and the double counterpoint of laying equal stress on causes speed of welding slow, and production efficiency is low.And the design of the relevant separate assembling stirring-head of report at present; The main scheme that adopts has two kinds: the one, in patent US006139985A and CN101559535; Employing has been simplified the manufacture process again after mixing needle weares and teares with the scheme that mixing needle separates with the shaft shoulder, has reduced the processing and manufacturing cost; But because the mixing needle diameter dimension is very little, cause when welding mixing needle with shaft shoulder junction because the concentrated generation fracture damage that is prone to of stress; The 2nd, in patent CN101559533,, solved the problem of stirring-head welding different-thickness sample to a certain extent through the mode that the operate portions section is separated with the clamping part section; But because quality of fit is had relatively high expectations between operate portions section and the clamping part section; Not only processing request is high, and is prone to cause bigger erection stress, and is not easy to long-time use; Can produce big gap, influence welding quality.
According to retrieval, still there is not report to relate to a kind of stirring-head of combined sleeve formula to pertinent literature.
Summary of the invention
The technical problem that solves
For fear of the weak point of prior art, the present invention proposes a kind of combined type stirring friction welding agitator head to different-thickness sheet material, can reduce the processing and manufacturing cost of stirring-head, and stirring-head is changed efficient when improving welding different-thickness sheet material.
Thought of the present invention is: to the combination stirring friction welding agitator head of different thicknesss of slab; This combined type stirring-head is made up of center matrix and sleeve, wherein center matrix comprise cramping body, shoulder block, the post that is threaded, the center matrix shaft shoulder and center matrix mixing needle.Sleeve comprises sleeve retained part, threaded connection hole, the sleeve shaft shoulder and sleeve mixing needle.Sleeve is connected through threaded engagement with center matrix.Center matrix and sleeve all are formed in one, and center matrix can be used as independently that stirring-head welds thin plate, and there are two planes parallel to each other the sleeve outside as the sleeve retained part, is used for sleeve is loaded and unloaded.The outer surface of post of being threaded has the screw thread and the internal surface of hole threads engaged that is threaded.Sleeve needle is to different sheet metal thicknesses, to a series of different sizes should be arranged.
