Machinery Castings Surface Repair Method For Defects To Hide Machinery Castings surface repair method for defects to hide Cast iron platform, inspection plate, cast iron plate, machine tool Machinery Castings in the production process will inevitably appear some small defects. Small Buzhi Yu re-Machinery Castings, that there are some small Machinery Castings defects how to solve this problem? Cast glue Simple, extensive Machinery Castingss, general repair does not require subsequent processing, and no special strength hardness requirements. The added value of such Machinery Castingss is relatively low. welding More than 90% of the foundry manufacturers have chosen welding to solve the production encountered in the Machinery Castings defects. Welding repair due to the use of metal filler (welding consumables generally match with the Machinery Castings material), welding performance can basically meet the base metal standard, and simple operation, high welding efficiency, many manufacturers recognized and trusted. Currently on the market, more types of welding machines, used in defect repair, generally have the following: Welding machine: cast iron, cast steel welding more use of the traditional way. Advantages: repair large defects, high efficiency. Disadvantages: solder joints on the hardness is too high, the internal stress, prone to cracks, generally also need to heat treatment to meet the processing requirements. And due to welding conditions, the internal easy to produce pores, slag and other secondary defects. TIG welding: precision Machinery Castingss (alloy steel, stainless steel precision Machinery Castings), aluminum alloy die Machinery Castings use of argon arc welding machine welding. Part of the mold manufacturing and repair manufacturers, but also the use of the welding machine repair mold defects. (1) Advantages: high welding efficiency, precision higher than the welding machine. More types of welding wire, stainless steel, aluminum alloy products on the most widely used Can be used for welding, strength to teach high. (2) Disadvantages: for defect repair, small defects repair (stomata, trachoma), due to the impact is too large, there are traces of the pool edge. Welding steel has a hard spot. Due to heat effects, welding of colored Machinery Castingss or thin-walled parts, easy to produce heat distortion. Operational requirements are higher. Cold welding machine Is the beginning of the 21st century, the birth of the new repair technology, welding process due to the workpiece heat is very small, was a cold welder. After several years of development, welding machine application direction and technology have been a great development, has been in the repair market occupies a large share. In accordance with the repair product categories are: placement machine and EDM repair welding machine. Mounter The use of instantaneous high-frequency discharge principle will paste (0.05-0.20mm) paste to the workpiece surface, the maximum thickness of each paste with the thickness of the same weld, welding quality depends on the discharge is uniform. Suitable for workpiece wear, processing tolerance repair, in the mold market has a certain influence. The machine can also be welding powder (or processing waste), filled into the defect (such as trachoma), after the discharge repair. After repair the workpiece color is small. The disadvantage is that the speed of repair is slower. The common drawback of cold welding machine and placement machine is that welding efficiency is not as high as that of welding machine and argon arc welding machine, but its outstanding advantages make people prefer cold welding when repairing millimeter defect and processing surface defect.

Površine odljevaka strojeva popravak metoda za nedostatke sakriti Lijevanog željeza platforma, tablicama, lijevano željeznu ploču, alatni strojevi odljevaka u procesu proizvodnje neizbježno će se pojaviti neki mali nedostaci. Mali Buzhi Yu re-strojevi odljevaka, da postoje neke mali nedostaci strojevi odljevaka kako riješiti ovaj problem? 1. gips ljepilo Jednostavno, opsežan strojevi Castingss, generalni popravak ne zahtijeva naknadnu obradu, i nema posebnu snagu tvrdoće zahtjeve. Dodana vrijednost takvih strojeva Castingss je relativno nizak. 2. zavarivanje Više od 90% proizvođača ljevaonica odabrali zavarivanje riješiti proizvodnje u oštećenja strojeva odljevaka. Zavarivanje popravak zbog korištenja metala punila (zavarivanje potrošni općenito odgovara strojevi odljevaka materijal), zavarivanje performanse mogu u osnovi zadovoljavaju standard kovina, i jednostavan rad, visoka zavarivanje učinkovitosti, mnogi proizvođači priznati i pouzdani. Trenutno na tržištu, više vrsta aparata za varenje, koristi se u defekt popravka, općenito su sljedeće: Za zavarivanje: lijevanog željeza, lijevanog čelika zavarivanje više korištenje na tradicionalan način. Prednosti: popravak velikih nedostataka, visoka učinkovitost. Nedostaci: spoj pregib na tvrdoće je previsoka, unutarnji stres, sklona pukotine, općenito morate toplinske obrade u susret zahtjevima obrade. I treba da zavarivanje uvjeti, unutarnje lako proizvesti pore, troske i drugi sekundarni nedostaci. TIG zavarivanje: preciznost strojeva Castingss (legure čelika, nehrđajućeg čelika preciznost strojeva odljevci), aluminijske legure umrijeti strojevi za betoniranje koristiti Argon luk za zavarivanje za zavarivanje. Dio kalup proizvodnja i popravak proizvođača, ali i korištenje za zavarivanje za popravak plijesni oštećenja. (1) prednosti: visoka zavarivanje učinkovitost, preciznost veći nego za zavarivanje. Više vrsta zavarivanja žice, nehrđajući čelik, aluminijske legure proizvoda na koji se najčešće koristi može koristiti za zavarivanje, snage naučiti visoko. (2) nedostaci: za popravak kvara, popravak mali nedostaci (puči, očne bolesti), zbog utjecaja je prevelika, postoje tragovi rubu bazena. Zavarivanje čelika ima tvrdo mjesto. Zbog topline, zavarivanje u boji strojevi Castingss ili tankih dijelova, lako proizvesti toplinu izobličenja. Operativni zahtjevi su više. 3. hladno zavarivanje stroj Početak 21 stoljeća, rođenje nove tehnologije popravka, zavarivanja zbog izratka topline je vrlo mala, je hladno Zavarivač. Nakon nekoliko godina razvoja, zavarivanje stroj program smjera i tehnologija su veliki razvoj, je bio u popravku tržištu zauzima veliki udio. U skladu s popravka kategorije proizvoda su: postavljanje stroja i EDM popravak aparata za zavarivanje. 4. nadriliječnik Korištenje trenutačan visokofrekventno pražnjenje princip će tijesto (0.05-0.20 mm) Zalijepi na površini obratka, Maksimalna debljina svakog tijesto debljine isto zavariti, kvalitetu zavarivanja ovisi o iscjedak je jedinstven. Pogodno za obratka habanje, obrada tolerancije popravak, kalup tržištu ima utjecaja. Stroj može također biti zavarivanje u prahu (ili obradu otpada), ispunjen u defekt (kao što su očne bolesti), nakon pražnjenja popravak. Nakon popravka izratka boja je mala. Nedostatak je da brzina popravka je sporiji. Zajednički nedostatak hladno zavarivanje stroj i prostor za je da zavarivanje učinkovitost nije visoka kao što je zavarivanje stroj i argona luk za zavarivanje, ali njegove izuzetne prednosti da se ljudi vole hladno zavarivanje kada popravak mm defekta i obrada površine defekt.
