Description
Technical field
The present invention relates to metal welding and increases material manufacturing technology field, more particularly to a kind of dead axle shoulder agitating friction weldering
Dead axle shoulder device and increasing material manufacturing method.
Background technology
Dead axle shoulder agitating friction welding technology is a kind of innovation and development of convention stir friction welding technology, belongs to Solid-phase welding skill
Art, its principle is that shaft shoulder fixation does not rotate, and mixing needle rotation is rotating insertion by weldering part, then along quilt using mixing needle
The interface to be welded for welding part is moved forward, stirring, friction by mixing needle to material, material to be welded is heated to thermoplastic character
State, under the mixing needle at a high speed drive of rotation, the rings of material in mecystasis is shifted from the front to the back around stirring-head, while dead axle
The forging and stamping effect of shoulder Resistance of Weld Metal, material diffusion connection forms solid diffusivity between fine and close metal under heat-machine synergy.
Relative to convention stir friction welding technology, the characteristics of dead axle shoulder agitating friction welding technology still has convention stir friction welding (FW), simultaneously
Also there is oneself unique advantage：Can be for solving titanium alloy agitating friction weldering because thermal conductivity factor is poor, welding temperature gradient is big
Caused by structure property it is uneven the problem of.In welding process, the shaft shoulder does not rotate, mixing needle rotation, the shaft shoulder may be designed to
The shaft shoulder that angle welding coordinates, successfully realizes the welding of T connector and corner joint angle welding at present, can obtain spirogyrate circle
Slip over the fillet welding joint crossed and intensity increases compared with fusion welding；Dead axle shoulder agitating friction welding technology can realize addition filling
The welding of material, with reference to more than 2 points, dead axle shoulder agitating friction welding technology is made the appropriate adjustments just can realize agitating friction without
Surplus near-net-shape increasing material manufacturing, has not yet to see correlative study and report.
During dead axle shoulder agitating friction weldering, the shaft shoulder, which is fixed, not to be rotated, mixing needle rotation, based on dead axle shoulder agitating friction weldering
Technical characterstic, stirring-head is necessarily designed to special structure form, causes whole stirring-head length longer, and mixing needle diameter compared with
Small (when diameter is big, difficult forming easily produces defect), belongs to thin and long units；, generally will even in order to increase the rigidity of stirring-head
Socket part sets up the relatively thick of meter separately, causes mixing needle excessively lofty with coupling part, is also easy to produce stress concentration, easy fracture, in rotation feelings
Under condition, long stirring-head is also easy to produce eccentricity issues, mixing needle and metal inner surface direct friction, and mixing needle easy fracture fails, for
Problem of stress concentration, general method is connected using arc transition mode.But mixing needle rubbing crack problem is directed to, at present not yet
There is solution.
The content of the invention
It is an object of the invention to provide a kind of dead axle shoulder device of dead axle shoulder agitating friction weldering and increasing material manufacturing method, solve
In the prior art the problem of mixing needle rubbing crack, it is three-level stepped hole to set inside dead axle shoulder, and alignment bearing is in top bar hole
Fixed stirring-head is held, mixing needle and hole of getting out of a predicament or an embarrassing situation are using interference fit, and auxiliary centering increases stirring-head rigidity, solved because of stirring
Long, offset causes the problem of mixing needle premature failure fails with wall friction in dead axle shoulder greatly.Dead axle shoulder is additionally provided with rolling
Wheel bearing, and roller bearing and mixing needle synchronizing moving, aid in workpiece pressing, solve because dead axle shoulder narrow space and caused by dress
Press from both sides difficult problem.Rolled with weldering, improve seam organization and stress distribution, reduce seam deformation, the present invention is filled by dead axle shoulder
No surplus agitating friction increasing material manufacturing can be carried out by putting, and realize that near-net-shape is manufactured.
To achieve the above object, the invention provides following technical scheme：
