Among the various ownership enterprises, the large-scale annual output of die-casting parts is 10,000 tons, the maximum annual output is 60,000 tons, the medium-sized annual output of die-casting parts is about 5,000 tons, and the small-scale annual output of die-casting parts is also several hundred tons. . The proportion of various die-casting parts in the total amount of die-casting Ebitundu, Aluminium Alloy ekola ebitundu nga 83%, Zinc alloy ekola ebitundu 15%, ate Gold left ekola ebitundu 2%, nga ku zino ebitundu nga obukadde 5.6 eza aluminum alloy die-casting parts zakolebwa mu 2014.
The main output of die-casting products is mainly automobile and motorcycle parts. The die-casting parts used in each automobile are gearbox housing, cylinder block and crankcase quasi-die casting. The average die-casting part of each car is 75 kg, total weight. It accounts for more than 50% of the total production of die-casting parts in China.
Obutuufu bw’okukola die castings bungi nnyo, okusinga omuli okusena, okusala, okuweta n’enkola endala.
Mu CNC center, ebyuma bya CNC eby’ebisiki bitaano n’ebya CNC bikozesebwa mu kukola ebyuma. okukola dizayini y’ebikozesebwa ng’ebyo eby’omutindo ogwa waggulu ekozesa ebikozesebwa eby’amaanyi eby’omukka ogw’amaanyi nga ssilindala. ezikoseddwa enkola ez’ennono, ebisinga obungi ku biwedde ebikoleddwa mu ngeri entuufu biba bifuuse abakola ebintu ebitera okuba n’omuwendo omunene ogw’ebiwundu, era enkola y’okukola Confused: Lwaki processing precision y’ebyuma bye bimu ebiyingizibwa mu ggwanga mu kukola eby’omunda mu ggwanga eri wala nnyo okuva ku bigwira?
Through the search for various reasons, it was finally found that the timeliness and accuracy of the operation of a series of pneumatic components such as cylinders in the original CNC machine tools are crucial to the accuracy of the machining, and the motion of the pneumatic components is closely related to the quality of the air source. However, in most of the existing die-casting plants in the configuration of the air compressor system, the most traditional drying method, that is, the post-cooling Dryer ekozesebwa okunyogoza n'okukala. ensonga ya puleesa y'empewo enyigiriziddwa oluvannyuma lw'okunyogoza n'okukala okutwalira awamu eri wakati wa +10 diguli C ne +15 diguli C. (esinga ku mutindo gw'amakolero g'ebyuma JB/T5967-2007 ebyetaago eby'omutendera ogw'omukaaga);
Ebitundu by’empewo ebikozesebwa ku byuma bya CNC eby’obutuufu obw’amaanyi byetaaga bulungi ensonga ya puleesa omusulo okubeera wansi wa +3 diguli (okusinziira ku mutindo gw’amakolero g’ebyuma JB/T5967-2007 ebyetaago by’ekibiina bina), ebirimu obunnyogovu mu mpewo enyigirizibwa bisukka nnyo ku byuma bye byetaagisa.
After finding out the cause, the post-processing equipment was immediately rectified, and the original cold-drying machine was replaced by a core-adsorption dryer. The pressure dew point after replacement could reach -20℃, which fully met the production requirements. After one month, statistics and analysis were carried out on the precision of the production defective products and finished products. It was found that the defective products were reduced by 5% era obutuufu bwalongooseddwa nnyo.
