Abstract
The utility model relates to a stirring needle for surface stirring friction, which is applied to the machining process of surface stirring friction, and consists a needle body (1) and a needle head (2), wherein the needle body (1) is cylindrical or frustum-shaped, and the needle head (2) is arranged at one end of the needle body (1). The stirring needle for surface stirring friction is characterized in that the needle head (2) is gradually sunken from the two edges to the center, and stripes diffused from inside to outside are arranged on the needle head (2). The stirring needle for surface stirring friction is required to only cause the material deformation within the range of 0.02 to 0.8 mm of the surface layer of the workpiece during the machining. The corresponding machining requirements are that the rotating speed of the stirring needle is 200 to 800 circle /minute, and the transverse moving speed is 20 to 50 mm /minute. The stirring needle for surface stirring friction has an excellent machining effect and a simple structure, and is easy to operate.
Description
Technical field
The utility model relates to the metal material processing method, provides a kind of surface stirring friction to use mixing needle especially.
Background technology
Friction Stir is the huge solid-state welding process method of a kind of using value; Its operation principle introduction is following: the nonexpendable soldering appliance of being made up of a mixing needle and its pedestal rotates at a high speed and mixing needle is inserted into desire between the connecting plate; When the shaft shoulder with after surface of the work contacts, mixing needle is done transverse movement simultaneously along seam.Violent friction between soldering appliance and workpiece causes the welding zone temperature obviously to raise, and causes the material plasticizing.The effect of mixing needle is the material that stirs the weld metal zone, makes it produce plastic flow and mixing, and the effect of the shaft shoulder is that the material that is stirred distortion by mixing needle is applied the forging effect, thereby forms closely knit flawless weld seam.
Based on the basic principle of friction Stir, develop and the processing of a kind of material microstructure modification technology-agitating friction, the violent plastic deformation of material, mixing and the temperature rise that promptly utilizes soldering appliance and caused realizes closeization, refinement and the homogenising of block materials.To common friction Stir/processing, the thickness of welding/processing district depends on the length of stirring-head, and according to the thickness of workpiece, the length of stirring-head does not wait to tens millimeters from several millimeters.Yet for some practical applications, requirement mainly be the surface property of workpiece, only need in this case carry out processing modified getting final product to the surface of workpiece.Obviously, it is processing modified that the instrument that contains the mixing needle design that common friction Stir/processing is used is not suitable for surface stirring friction.
People expect to obtain the better surface stirring friction of a kind of technique effect and use mixing needle.
Summary of the invention
The purpose of the utility model is to provide the mixing needle of the better surface stirring friction processing of a kind of technique effect usefulness.
A kind of surface stirring friction of the utility model is used mixing needle, is applied in the surface stirring friction process, and said surface stirring friction is made up of needle body 1, syringe needle 2 with mixing needle; Wherein: needle body 1 is cylindrical or the taper type structure; Syringe needle 2 is arranged on an end of needle body 1; It is characterized in that: syringe needle 2 is the low version that concaves between edge senior middle school, and syringe needle 2 is provided with the striped of dispersing from inside to outside.
The low structure that concaves is specially the pyramidal pits of indent between the edge senior middle school of syringe needle 2.It is the combination of curve and straight line that syringe needle 2 is provided with the striped of dispersing from inside to outside, and the place of keeping to the side is a straight line, is curve away from edge, curve and linear sequence smooth connection.
Add and require only to cause the material deformation in the workpiece surface 0.02-0.8 mm scope man-hour.Corresponding processing request: 200 ~ 800 rev/mins of mixing needle velocities of rotation, the horizontal speed of service 20 ~ 50 mm/min.
The utility model processing effect is good, and is simple in structure, easy operating.
Description of drawings:
Fig. 1 for surface stirring friction with mixing needle front view (cutaway view);
Fig. 2 is the right view (front view of syringe needle 2) of figure one.
The specific embodiment:
A kind of surface stirring friction is used mixing needle, referring to accompanying drawing 1,2; Be applied in the surface stirring friction process, said surface stirring friction is made up of needle body 1, syringe needle 2 with mixing needle; Wherein: needle body 1 is cylindrical or the taper type structure; Syringe needle 2 is arranged on an end of needle body 1; It is characterized in that: syringe needle 2 is the low version that concaves between edge senior middle school, and syringe needle 2 is provided with the striped of dispersing from inside to outside.
The low structure that concaves is specially the pyramidal pits of indent between the edge senior middle school of syringe needle 2.It is the combination of curve and straight line that syringe needle 2 is provided with the striped of dispersing from inside to outside, and the place of keeping to the side is a straight line, is curve away from edge, curve and linear sequence smooth connection.
Add and require only to cause the material deformation in the workpiece surface 0.02-0.8 mm scope man-hour.Corresponding processing request: 200 ~ 800 rev/mins of mixing needle velocities of rotation, the horizontal speed of service 20 ~ 50 mm/min.
The present embodiment processing effect is good, and is simple in structure, easy operating.
