Abstract
A stirring pin for surface friction stir is applied to a machining process for surface friction stir. The stirring pin for surface friction stir comprises a pin body (1) and a pin head (2), wherein the pin body (1) is in a cylindrical or frustum structure, and the pin head (2) is arranged at one end of the pin body (1) and is in a structural form high at the edge and concave inwards in the middle. The pin is characterized in that a small pitted-surface boss (3) provided with embosses is arranged in the center of the pin head (2), and stripes diverging from inward to outward are arranged on the rest portion expect the small pitted-surface boss (3) on the end face of the pin head (2). The stirring pin is excellent in processing effect, simple in structure and easy to operate.
Description
Technical field
The present invention relates to the metal material processing method, a kind of mixing needle is provided especially.
Background technology
The agitating friction welding is the huge solid-state welding process method of a kind of using value, its operation principle is described below: the nonexpendable soldering appliance High Rotation Speed that is comprised of a mixing needle and its pedestal is inserted between the wish connecting plate mixing needle, 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.
People expect to obtain the better mixing needle of a kind of technique effect.
Summary of the invention
The purpose of invention is to provide the mixing needle of the better surface stirring friction processing of a kind of technique effect usefulness.
A kind of mixing needle of the present invention is applied in the surface stirring friction process, and described stirring needle for surface stirring friction is made of needle body 1, syringe needle 2; Wherein: needle body 1 is cylindrical or the taper type structure; Syringe needle 2 is arranged on an end of needle body 1; Syringe needle 2 is the low version that concaves between edge senior middle school; It is characterized in that: syringe needle 2 centre are the pitted skin small boss 3 that is provided with salient point, and the syringe needle 2 end face remainders except the pitted skin small boss 3 are provided with the striped of dispersing from inside to outside.
Add the material deformation that requires man-hour only to cause in the workpiece surface 0.01-2.0 mm scope.Corresponding processing request: 150 ~ 400 rev/mins of mixing needle velocities of rotation, the horizontal speed of service 10 ~ 25 mm/min.
Processing effect of the present invention is good, and is simple in structure, easy operating.
Description of drawings:
Fig. 1 is 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 mixing needle (referring to accompanying drawing 1,2) is applied in the surface stirring friction process, and described stirring needle for surface stirring friction is made of needle body 1, syringe needle 2; Wherein: needle body 1 is cylindrical or the taper type structure; Syringe needle 2 is arranged on an end of needle body 1; Syringe needle 2 is the low version that concaves between edge senior middle school; It is characterized in that: syringe needle 2 centre are the pitted skin small boss 3 that is provided with salient point, and the syringe needle 2 end face remainders except the pitted skin small boss 3 are provided with the striped of dispersing from inside to outside.
Add the material deformation that requires man-hour only to cause in the workpiece surface 0.01-2.0 mm scope.Corresponding processing request: 150 ~ 400 rev/mins of mixing needle velocities of rotation, the horizontal speed of service 10 ~ 25 mm/min.
The present embodiment processing effect is good, and is simple in structure, easy operating.
