Abstract
A stirring pin for surface stirring and rubbing is used in a machining process for surface stirring and rubbing. The stirring pin for surface stirring and rubbing is composed of a pin body (1) and a pin head (2), wherein the pin body (1) is in a cylindrical or conical structure, and the pin head (2) is arranged at one end of the pin body (1). The stirring pin is characterized in that the pin head (2) is in a concave structure with a high edge and a lower middle and provided with stripes diverging from inside to outside. During processing, material deformation of a workpiece surface is required to be in a range of 0.02mm to 0.8mm. Corresponding processing requirements include that the rotation speed of the stirring pin is 200 to 800 turns/minute, and the transverse operating speed is 20 to 50 millimeters/minute. The stirring pin for surface stirring and rubbing is good 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 stirring needle for surface stirring friction 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.
Based on the basic principle of agitating friction welding, develop a kind of material microstructure modification technology-agitating friction processing, material severe plastic deformation, mixing and the temperature rise that namely utilizes soldering appliance to cause realizes closeization, refinement and the homogenising of block materials.To common agitating friction welding/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 use for some engineerings, 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 the welding/processing of common agitating friction is used is not suitable for surface stirring friction.
People expect to obtain the better stirring needle for surface stirring friction of a kind of technique effect.
Summary of the invention
The object of the present invention is to provide the mixing needle of the better surface stirring friction processing of a kind of technique effect usefulness.
A kind of stirring needle for surface stirring friction 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; It is characterized in that: syringe needle 2 is the low version that concaves between edge senior middle school, and is provided with the striped of dispersing from inside to outside on the syringe needle 2.
The low structure that concaves is specially the pyramidal pits of indent between the edge senior middle school of syringe needle 2.Being provided with the striped of dispersing from inside to outside on the syringe needle 2 is the combination of curve and straight line, and the place of keeping to the side is straight line, is curve away from edge, and curve and linear sequence are in smoothing junction.
Add the material deformation that requires man-hour only to cause in the workpiece surface 0.02-0.8 mm scope.Corresponding processing request: 200 ~ 800 rev/mins of mixing needle velocities of rotation, the horizontal speed of service 20 ~ 50 mm/min.
Processing effect of the present invention is good, and is simple in structure, easy operating.
