Title (EN) BELT PULLEY POWDER METALLURGY METHOD
(FR) PROCÉDÉ DE MÉTALLURGIE DES POUDRES POUR POULIES À COURROIE
(ZH) 一种皮带轮粉末冶金方法
Abstract:
(EN) A belt pulley powder metallurgy preparation method, specifically comprising: uniformly mixing 1-5 parts of a graphite powder, 5-10 parts of an electrolytic copper powder, 2-8 parts of palmitic acid, 5-8 parts of nickel oxide, 50-98 parts of a reduced iron powder, 1-5 parts of manganese sulfide, 5-10 parts of chromium powder, 0.2-0.5 parts of tin powder, 0.5-1 part of micronized wax and 0.2-0.5 parts of a reinforcing agent; pressing the mixture to form a blank of a pre-set shape under the pressure of 60-70 MPa; feeding said product blank into a sintering electric furnace and sintering same into a semi-finished part; subjecting the semi-finished part to oil immersion, steam treatment, and cleaning to obtain a finished product. The raw material composition of the belt pulley is less polluting to the environment, and said method simplifies production steps and improves the production efficiency.
(FR) L'invention concerne un procédé de préparation de métallurgie des poudres pour poulie à courroie, comprenant spécifiquement : le mélange uniforme de 1 à 5 parties d'une poudre de graphite, 5 à 10 parties d'une poudre de cuivre électrolytique, 2 à 8 parties d'acide palmitique, 5 à 8 parties d'oxyde de nickel, 50 à 98 parties d'une poudre de fer réduit, 1 à 5 parties de sulfure de manganèse, 5 à 10 parties de poudre de chrome, 0,2 à 0,5 partie de poudre d'étain, 0,5 à 1 partie de cire micronisée et 0,2 à 0,5 partie d'un agent de renforcement ; le pressage du mélange pour former une ébauche d'une forme prédéfinie sous la pression de 60 à 70 MPa ; l'introduction de ladite ébauche de produit dans un four électrique de frittage et le frittage de celle-ci en une pièce semi-finie ; la soumission de la pièce semi-finie à une immersion dans l'huile, un traitement à la vapeur et un nettoyage pour obtenir un produit fini. La composition de matière première de la poulie à courroie est moins polluante pour l'environnement, et ledit procédé simplifie les étapes de production et améliore l'efficacité de production.
(ZH) 一种皮带轮的粉末冶金制备方法,具体为:将石墨粉1-5份、电解铜粉5-10份、软脂酸2-8份、氧化镍5-8份、还原铁粉50-98份、硫化亚锰1-5份、铬粉5-10份、锡粉0.2-0.5份、微粉蜡0.5-1份和增强剂0.2-0.5份混合均匀;在60-70MPa的压强下压制成设定形状的坯料备用;将所述产品坯料件送入烧结电炉中烧结成半成品件;经过浸油和蒸汽处理,清洗得到成品。该皮带轮的原料组成对环境污染小,该方法简化生产步骤,提高生产效率。
