Description
Technical field
The present invention relates to the control device and the method for friction welding (FW) overlap control technology, particularly a kind of friction welding scrap rubber of motorcycle shock absorber oil storage cylinder.
Background technology
With Continuous Drive rubbing method welding motorcycle shock absorber oil storage cylinder, be regarded as a kind of welding method efficiently.At present, both at home and abroad about the Continuous Drive Friction Welding connection technology, a lot of patents and application are disclosed, but the patent in removing and control narrow tube structure friction welding joint aspect the overlap is few, (name is called " new device of removing the friction welding overlap " only to disclose the patent of the outer overlap of a removal, application number is 90221183.8), it is a kind of in friction welding process, by die-cut mode, remove the device of the outer overlap of workpiece welding, this device is by push action cylinder, mobile holder, the inside and outside stamping knife of annular, pressing plate, the stamping knife frame, fork-shaped bearing and connector are formed, can in welding process, finish multi-step process simultaneously, improve productivity ratio, be applicable to the outer overlap of removal bar and the inside and outside overlap of major-diameter thick-wall pipe fitting.But this apparatus structure more complicated can't be removed overlap in the minor diameter pipe fitting friction welding joint, more can not solve the control problem of overlap in the semiclosed pipe fitting friction welding joint of minor diameter.
The motorcycle shock absorber oil storage cylinder parts are made up of oil storing tube, suspension ring and plug, and the postwelding structure of shock absorber oil storage cylinder is a semiclosed member, have a large amount of friction welding (FW) overlaps in the inside of oil storing tube.The existence of overlap in these welding, be to have influenced the assembling of back process components in oil drum on the one hand, be on the other hand in the damper course of work, be easy to make overlap local shedding in the welding, the generation regulus is cut and is entered in the damping fluid, quicken the wearing and tearing of damper, reduce the service life of damper, even burst accident takes place.Therefore, need to eliminate or reduce overlap in the motorcycle shock absorber oil storage cylinder friction welding joint, perhaps control overlap form in the friction welding joint.Yet the interior overlap of friction welding (FW) of removing or controlling in the motorcycle shock absorber oil storage cylinder exists following difficult:
(1) diameter of shock absorber oil storage cylinder is less, can't big mechanically cutting mechanism be set in pipe inside;
(2) barrel of shock absorber oil storage cylinder is too thin, is again semiclosed member, and control measure are meticulous;
(3) the overlap control device will guarantee accurate positioning, and device has convertibility and dismounting property;
(4) want after the overlap control device has welded and can easily take out, and good maintenance;
(5) because friction welding (FW) production efficiency height, weld interval is short, interior overlap temperature is higher, when overlap is controlled in welding, consider the influence to friction welding (FW) production efficiency, the economy of control method and device, reliability and validity can not adopt the method and apparatus that makes cost increase too high, complex structure, complex operation, want to satisfy requirements of large-scale production, and can improve the quality of friction welding joint.

The 3rd step, clamping oil storing tube: the control device of friction welding scrap rubber of motorcycle shock absorber oil storage cylinder as claimed in claim 1 is packed in the oil storing tube (2), again with the oil storing tube clamping on friction-welding machine endwisely slips portion, and move to rotating part, oil storing tube (2) is contacted with plug (1) carry out friction welding;
In the 4th step, after welding was finished, friction-welding machine endwisely slipped and slides backward in the portion, the control device of friction welding scrap rubber of motorcycle shock absorber oil storage cylinder ejects automatically, the clamping device of portion and rotating part of endwisely slipping unclamps simultaneously, and welding work pieces takes out, and welding process finishes.
5, the control method of friction welding scrap rubber of motorcycle shock absorber oil storage cylinder, its step is as follows:
The first step, the building block of improvement oil drum: enlarge the mouth diameters of oil storing tube (2) friction welding end, form horn mouth; Make the diameter 1～30mm of the diameter of this end of oil storing tube, oil storing tube friction welding (FW) contact portion is positioned on the plug depression oral area flat surface in addition greater than plug (1) depression oral area;
In second step, the clamping plug: suspension ring (3) and plug (1) are welded together, be installed in the auxiliary clamp (18) again, then, clamping is on the rotating part of friction-welding machine in the lump;
The 3rd step, clamping oil storing tube: the control device of friction welding scrap rubber of motorcycle shock absorber oil storage cylinder as claimed in claim 1 is packed in the oil storing tube (2), again with the oil storing tube clamping on friction-welding machine endwisely slips portion, and move to rotating part, oil storing tube (2) is contacted with plug (1) carry out friction welding;
In the 4th step, after welding was finished, friction-welding machine endwisely slipped and slides backward in the portion, the control device of friction welding scrap rubber of motorcycle shock absorber oil storage cylinder ejects automatically, the clamping device of portion and rotating part of endwisely slipping unclamps simultaneously, and welding work pieces takes out, and welding process finishes.
6, according to the control method of the friction welding scrap rubber of motorcycle shock absorber oil storage cylinder of one of claim 2-5, the technological parameter of its friction welding is: friction rotating speed 1900～2500r/min, friction pressure 0.1～1.2MPa, upsetting force 0.5～2.0Mpa, fraction time 0.2～1.2s, axially shortening amount 2.2～3.4mm.
