Abstract
The invention discloses a static shaft shoulder stirring head with reduced viscosity. The static shaft shoulder stirring head comprises a stirring needle, a shaft shoulder and a thrust ball bearing, wherein the shaft shoulder and the thrust ball bearing are sequentially connected to the rear part of the stirring needle, and the rear end of the stirring needle is fixedly connected with a power transferring part. The rear end of the stirring needle is fixedly connected with the power transferring part through a screw. The front end of the stirring needle is a circular conical surface which is provided with bulges or pits, and the stirring needle is manufactured by adopting H13. The heights of the bulges are between 0.5mm-3mm, the interval between the adjacent bulges is between 0.5-3mm, and the interval between the adjacent pits is 0.5-3mm; the included angle of the linear arrangement of the bulges or the pits and the axis of the stirring needle is between 80 degrees and 88 degrees. The static shaft shoulder stirring head with reduced viscosity has the beneficial effects of relatively low welding heat input, relatively small integral crystal particles in a weld zone, and relatively high weld comprehensive mechanical property. The viscosity of the stirring head caused by aluminum alloy can be obviously reduced, so that the stirring head is easy to maintain after welding, and the service life of the stirring head is prolonged.
Description
Technical field
The present invention relates to a kind of stirring-head, particularly a kind of dead axle shoulder visbreaking stirring-head.
Background technology
In recent years, along with high ferro technology introduction with constantly bring forth new ideas, the high ferro manufacturing industry of China is just constantly flourish, turns to world high ferro to produce power become inevitable by high ferro big producing country of the world.The large cake of this part of high ferro market in global range, interstate competition is further fierce, and can the quality and safety of high ferro be the prerequisite taking down order in competition.
For sleeper beam in high ferro car body, the welding of the Aluminum Alloy Plate vitals such as coupler seat, most domestic enterprise still adopts MIG multi-pass welding, and not only the welding process time is long, workman's working condition is poor, and postwelding defect is many, repair difficulty.Agitating friction solder technology is compared with traditional arc-welding, and the mechanical property of weld seam improves a lot, and weld defect is few, and workman's working condition is greatly improved.In existing single shaft shoulder stirring-head welding process, mixing needle makes the crystal grain in nugget district very tiny for the stirring fragmentation of crystal grain, and mechanical property is very high.But the shaft shoulder is less for the stirring fragmentation of mother metal, the rub heat that produces of the shaft shoulder and mother metal inputs very large, and make the crystal grain of the thermomechanical zone of influence and heat affected area comparatively large, mechanical property is lower.In addition, the easy adhesion Al-alloy metal of groove on postwelding mixing needle surface, not only affects the quality of weld seam, and it is more difficult that the stirring-head after sticky aluminium is safeguarded, reduces the service life of stirring-head.Therefore, a kind of dead axle shoulder visbreaking stirring-head is designed imperative.
Summary of the invention
The object of the invention is to there is mixing needle to solve in the welding of existing single shaft shoulder agitating friction the problem of aluminium and a kind of dead axle shoulder visbreaking stirring-head that provides are provided.
Dead axle shoulder visbreaking stirring-head provided by the invention includes mixing needle, the shaft shoulder and thrust ball bearing, and wherein the shaft shoulder and thrust ball bearing are connected to mixing needle rear portion in turn, and the rear end of mixing needle is fixedly connected with transmission power part.
The rear end of mixing needle is fixedly connected with by screw with between transmission power part.
The front end of mixing needle is a taper seat, and taper seat is provided with projection or pit, and mixing needle adopts H13 steel making.
Protruding height is within the scope of 0.5mm-3mm, and the spacing of adjacent protrusion is within the scope of 0.5-3mm; The degree of depth of pit is within the scope of 0.5-3mm, and the spacing of adjacent pit is within the scope of 0.5-3mm; And the linear array of projection or pit and mixing needle axle center angle are within the scope of 80 °-88 °.
The shaft shoulder adopts hot-work die steel making.
The model of thrust ball bearing is 51100,51101,51102,51103,51104,51105 or 51106.
Operation principle of the present invention:
Dead axle shoulder visbreaking stirring-head provided by the invention can be applied to high Fe in Al-alloy car body sleeper beam, the welding of the cut deals such as coupler seat, only have the upper surface of transmission power part, thrust ball bearing and mixing needle to rotate in welding process, and the lower surface of the shaft shoulder and thrust ball bearing is not all rotated.Because the shaft shoulder does not rotate, greatly will reduce thermal weld stress, the thermomechanical zone of influence and heat affected area scope are significantly reduced, weld seam welds primarily of single shaft shoulder stirring-head in traditional sense the nugget district composition produced.Because mixing needle is for the stirring fragmentation of crystal grain, make the crystal grain in nugget district very tiny, the mechanical property of weld seam entirety is greatly improved.In addition, the taper seat of mixing needle front end is processed with projection or pit that shape is spherical, cylindrical, six squares, square, rectangle or rhombus.This biomimetic features significantly can reduce the adhesiveness of aluminium alloy for stirring-head, not only makes stirring-head postwelding be easy to safeguard, and improves the service life of stirring-head.
Beneficial effect of the present invention:
Dead axle provided by the invention shoulder visbreaking stirring-head is carrying out only having mixing needle, thrust ball bearing upper surface in welding process and transmitting power part rotating, and the lower surface of the shaft shoulder and thrust ball bearing non rotating.Compared with takeing on stirring-head with the single shaft of traditional structure, under identical welding parameter, this dead axle shoulder visbreaking stirring-head thermal weld stress is less, and the overall crystal grain in weld metal zone is less, and weld seam comprehensive mechanical property is higher.Further, the taper seat of mixing needle front end is processed with convex closure or pit that shape is spherical, cylindrical, six squares, square, rectangle or rhombus.This biomimetic features significantly can reduce the adhesiveness of aluminium alloy for stirring-head, not only makes stirring-head postwelding be easy to safeguard, and improves the service life of stirring-head.
