Description
Technical field
The utility model 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 purpose of this utility model there is mixing needle glue the problem of aluminium and a kind of dead axle shoulder visbreaking stirring-head that provides to solve in the welding of existing single shaft shoulder agitating friction.
The dead axle shoulder visbreaking stirring-head that the utility model provides 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 utility model:
The dead axle shoulder visbreaking stirring-head that the utility model provides 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.
The beneficial effects of the utility model:
Dead axle that the utility model provides 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.
