Preferably; Said friction welding (FW) support is provided with a plate; The length direction of this connecting plate preheating unit up and down extends; Connect and this sliding pair along continuous straight runs setting through a pair of sliding pair between said adjustable shelf and the connecting plate, adjustable shelf is moved around between friction frame and upper and lower preheating unit, realize horizontal shift.
Preferably, said connecting plate is provided with a cylinder, and the cylinder axis in this cylinder is connected with adjustable shelf, and this cylinder drives adjustable shelf and on sliding pair, moves.
Preferably, the said preheating unit of going up comprises upper mounting plate and the last preheating mould that is provided with above the upper mounting plate, and said time preheating unit comprises the following preheating mould that is provided with below lower installation board and the lower installation board.
Preferably, said upper and lower preheating mould inside has fire-bar.When carrying out preheating, fire-bar can heat the preheating mould in the several seconds, and after preheating finishes, stops the fire-bar heating again at once, reduces the use of the energy like this.
Preferably; Vertically provided some axis of guides on the said upper and lower installing plate respectively, upper and lower installing plate can move up and down along the axis of guide, to realize that upper and lower preheating unit in opposite directions or opposing move mode; And the accurate positioning property of assurance installing plate, skew about not understanding.
Preferably, said top of going up the preheating mould is provided with upper cylinder, and the cylinder axis in the upper cylinder is connected with last preheating mould, and casing top half can drive the preheating mould and be shifted up and down along the axis of guide; The below of following preheating mould is provided with lower cylinder, and the cylinder axis in the lower cylinder is connected with following preheating mould, and following cylinder can drive down the preheating mould and be shifted up and down along the axis of guide.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
See also Fig. 1, Fig. 1 is a structural representation of the present invention.A kind of friction welding (FW) preheating mechanism shown in the figure, comprising: the friction welding (FW) support is characterized in that: the upper and lower installing plate that also comprises mutual horizontal parallel; Be provided with the preheating mould above the upper mounting plate; Be provided with down the preheating mould below the lower installation board, upwards vertically provided 4 axis of guides, provided 4 axis of guides on the lower installation board downward vertically at upper mounting plate; The top that should go up the preheating mould is provided with upper cylinder; Upper cylinder is fixed on the link, and the cylinder axis in the upper cylinder is connected with last preheating mould, and casing top half can drive the preheating mould and be shifted up and down along the last axis of guide; The below of following preheating mould is provided with lower cylinder, and lower cylinder is fixed on down on the link, and the cylinder axis in the lower cylinder is connected with following preheating mould, and following cylinder can drive down the preheating mould and be shifted up and down along the following axis of guide, realizes that upper and lower installing plate in opposite directions or opposing move mode.
Between upper and lower installing plate, be provided with the adjustable shelf of a horizontal shift, the friction welding (FW) support is provided with a plate, is connected through a pair of sliding pair between this connecting plate and the said adjustable shelf and this sliding pair along continuous straight runs is provided with.Then, connecting plate is provided with a cylinder, and the cylinder axis in this cylinder is connected with adjustable shelf, and this cylinder can drive adjustable shelf along moving around on the sliding pair, makes the adjustable shelf can be back and forth between friction welding support and upper and lower installing plate.
Said upper and lower preheating mould inside has fire-bar, and this fire-bar can the transient heating mould, with the preheating workpiece.
Before friction welding, be placed on workpiece to be welded on the adjustable shelf earlier, then, start cylinder, promote adjustable shelf forward between the upper and lower preheating mould at leisure.Then, upper and lower preheating mould stretches out under cylinder action separately, to the adjustable shelf direction move until with workpiece at a distance of several millimeters, at this moment, the fire-bar on the upper and lower preheating mould heats up rapidly in the several seconds and heating adjustable shelf workpiece up and down.About ten seconds, preheating finishes.At this moment, upper and lower preheating mould is by upper and lower cylinder pulling playback and cooling, and the effect through cylinder is retracted into adjustable shelf on the welding support again, and last, the starting friction soldering equipment carries out friction welding (FW) to workpiece on adjustable shelf.
Below only expressed embodiment of the present invention, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the patent of invention scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
Advantage of the present invention: simple in structure, easy to use, because of treating that the friction welding (FW) position is by preheating; The free activity space of its apparent motion unit activation and molecule is increased, fusion more easily during friction, the welding quality of raising friction welding (FW); Sticking into strips couplet of welding slag can not fall down in both sides; So do not weld dust, pick up about second because of being merely preheating time, so energy-saving effect is very obvious.
