Of bimetallic silk mother stick receive repair

7 document label piles up B one, deputy drive of mother of overview guide screw, silk, move point-blank in the machine tool in the orgnaization be used generally, the perpendicular shift that is like pillar of door of dragon of edge of beam of planer-type milling machine (W axis) , the ram perpendicular shift on slide (Z axis) , the level of slide edge beam is mobile (Y axis) , the level of workbench edge lathe bed moves. In the diameter bigger or the guide screw that filar mother rotates deputy in, design filar mother geminate metal structure commonly. Advocate if be based on,considered at 3 o'clock: It is stuff of economic copper metal. 2 be it is good to can repair dominance. If copper is qualitative whorl part wears away or after attaint invalidation, can use the coat of former steeliness, after building the cupreous part that goes damaging, qualitative liner of centrifugal mould copper, machine whorl part afresh next. 3 it is special structural demand. Be like: Coat is a gear, want to transfer power, be no good apparently with what copper pledges, and whorl part is clear also cannot with coat steel of a make it pledges, because this designs geminate metal structure, each one does his job. In deputy drive of mother of guide screw, silk, what damage above all is filar mother, traditional repair method is wear away whorl not all guide screw is on the machine tool nap, make up new filar parent by the snail tooth ply after repairing next. If of guide screw wear away in allow to continue inside scope of application, can change directly new silk mother. Be like general small-sized the filar mother that mother of complete copper silk also can seek spare parts to will damage directly is replaced come down. And of bimetallic silk mother change to compare a trouble, this involves 5 issues: Centrifugal mould technique makes mother of ① bimetallic silk, general plant does not have centrifugal mould requirement, cannot abstain; The n of ② centrifugal mould is inferior, do badly, cause slag inclusion, sand holes to discard as useless; The union of ③ copper and steel is not firm, often produce copper, steel to come off discard as useless; The coat of ④ nicety produces heat easily to be out of shape; ⑤ because afore-mentioned reasons, the spare parts of bimetallic silk mother produces difficulty and seldom be laid in or do not have reserve. As a result of afore-mentioned reasons, make geminate wire the question with difficult production of mother spare parts. Repair to do not cause long machine tool to stop wait for, must change bimetallic silk mother restrict parent of costly complete copper silk, such not only create serious waste, and the performance characteristics that reduced this part, changing steel-tooth into copper to age is improper apparently. Russia makes before 7288 model dragon door dig, what place of guide screw of shift of tool carrier slide matchs is bimetallic silk mother. Discover lapse of tool carrier shift, wear away badly via checking the cupreous whorl part that is bimetallic silk mother, grind entirely almost. This is a crucial and large facility, should clutch rush to repair. Cannot find spare parts at that time, although mechanical member Ceng Di gives spare parts to apply for, fail two years to make spare parts. Want to change its help sb to fulfill his wishes copper lash-up is repaired, but expect without copper of off-the-peg semifinished product casting however. Below this kind of circumstance, with stick received method to undertake repair gains a success. 2, the craft preparation before repair and note above all, the copper that damages in lathe admiral is qualitative inside whole vehicle divides echelon whorl share, carry common thread of M95 × 2mm. Should notice at 3 o'clock: ① does not use cooling fluid in treatment; ② whorl should be carried coarsely as far as possible, so that rise hind foreword is stuck with what copper covers receive strength, carry burr of the winkle that buckle a knife with the horn before losing best; Ply of ③ snail tooth should compare normal whorl a bit some thinner, so that stick,receive an agent to intervene. Next, look for simple semifinished product of a copper, material is ZQSn6-6-3. Will outside round car becomes M95 × 2mm. Also should notice at 3 o'clock, ① whorl is carried coarsely as far as possible; The Kong Yingkuo inside ② is become allowance, so that stick hind fine vehicle; ③ does not use cooling fluid, the attention keeps clean. 3, stick the option that receives a dose to choose to stick receive an agent to have 3 principles, ① is stuck receive intensity to want tall, fight come off function is close friends; ② solidify time should grow; ③ should suit permanent stick receive. Press these 3 principles, celebrate oxygen model permanent stick receive an agent to be best, be like: Of day hill, Le Tai, Beierzunna OK. The TS1272 that this exemple uses company of Beijing day hill to produce locks up solid agent. 4, stick receive 1. Qualitative liner clip holds good preparation copper to go up in machine tool clamping apparatus. 2. Drench appropriately on whorl of 2mm of × of M95 of steel qualitative coat on stick receive a dose, notice forehead drenchs more a few. 3. Drench appropriately on whorl of 2mm of × of M95 of cupreous qualitative liner on stick receive a dose, also should drench more in forehead a few. 4. With machine tool of proper revolution actuate, your copper pledges liner rotates. 5. Hold steel to pledge coat comes back his liner, notice right now, if discovery is stuck,receive a dose insufficient, but proper and supplementary. This working procedure wants special attention, must sticking the initiative solidify that receives a dose finish in time. The choice is stuck on the machine tool receive, come back to accelerate namely close career, decrease both come back agree time, the hand is moved coming back also is no good anyhow. If exceeded initiative solidify time, did not come back completely, or come back half, will not continue to operate, can remove car of cupreous qualitative liner only discard as useless, new preparation. Initiative solidify time is happy peaceful glue 15min, must abide by, and should stay have quite bounteous measure ahead of schedule. 6. Wait for stick receive a dose after complete solidify, go up machine tool finish machining. Place the bimetallic nut outfit after agglutinate on the machine tool, by original design steel the circle outside qualitative coat searchs, search precision 0.

02mm less than; Press the aperture inside blueprint requirement treatment, carry make thread of echelon of T90 × 6mm; End panel of fine vehicle around. 7. Bolt of outfit a junction of the edges of two sheets of paper is added in place of agglutinate of steel of two end panel, copper, this is a kind of traditional method, receive experience according to be being stuck for years, think but complete need not this action, was being added also is doubt of the heart that see solution only, without any action, because this kind is stuck,receive, both union is quite reliable. 5, conclusion is used stick receive a technology to replace bimetallic nut centrifugal mould craft is completely feasible, but fast rehabilitate a few bimetallic kind spare parts, reduce equipment to stop substantially long need a time, decrease stop engine loss, charge low, quality is good. With stick receive component of technical rehabilitate bimetallic to belong to " cold welding " technology, former steeliness coat won't produce heat to be out of shape, if former coat does not have tatty circumstance to fall, completely OK reuse.
