Description
Изобретение касаетс способа зг чалки дл бумагорезательных машин к чугунном iDTaMne, cocTOfliiiCx пуажона н матрнцы, омываемых B0;u)ii. что обеспечивает одновременно придание нужной формы ножам из )дпстой стали и их такалку.The invention relates to a method of chugs for shredders for cast iron iDTaMne, cocTOfliiiCx pojone n matrons, washed by B0; u) ii. which ensures at the same time giving the desired shape to the knives made of stainless steel and their takalka.
Изиеетные аналогичные штампы и тгрлспособле:1н дл одновременHGii закалки иправк ILTM за:лалки и пр}-;данп нужной формы издели м страдают тем недоетатком, что в ннх не достигаетс необходима скорость охлаждени при закалке изделий ;)ч углеродистой стали, а потому н не обеспечиваетс получение мйксн:.;аль;-10 возможной твердости, необходимой дл режущего инструмента.Similar stamps are also available: 1H for simultaneous HGii hardening ILTM replicas for: lalks and pr} -; danp of the desired shape of the product m suffers from the insufficient amount of cooling rate at hardening;) h of carbon steel and therefore not A mix:.; al; -10 possible hardness needed for the cutting tool is obtained.
В нреллагаемом способе этот недостаток устранен тем, что издели 3 штампе во врем их и;тампоБки охлаждают проточной водой, что обеспечивает получение ножеГ; с высокой (;стью и правильную их форму .In the proposed method, this disadvantage is eliminated by the fact that the products 3 are stamped during them and; the tampon caps are cooled with running water, which ensures the preparation of the knife; with high (; stew and their correct form.
На чертеже изображена схема закалсчиото штампа.The drawing shows a diagram zakalchioto stamp.
Ножи дл закалки нагреваютс в ь-.пе-Т.-ропеч или сол ной ванне до температуры 790-8iO.The quenching knives are heated in blu-te-t-ropech or a salt bath to a temperature of 790-8iO.
Закал-ку производ т в чугунном :11тампе. в котором одновременно придают пожу требуемую форму.Quenching is done in cast iron: 11 tampa. in which at the same time they give the fire the required shape.
Чугунный штамп еостоит из матрицы / }; пуансона 2, охлаждаемых проточной водой. Вода по шлангам, надетым ка трубки 3 проходит в полость матрицы 4 и пуансона 5, что создает услови дл полной закалки ножа.Cast iron stamp consists of a matrix /}; the punch 2, cooled with running water. Water through the hoses put on by the tube 3 passes into the cavity of the matrix 4 and the punch 5, which creates conditions for the complete hardening of the knife.
После закалки ножи отпускают при температуре 2/0-285. Твердость ножей после и отпуск по Re 54-57.After quenching, the knives are released at 2 / 0-285. Hardness of knives after and holiday according to Re 54-57.
П р -е д м е т изобретени P r-e d mete inventions
Способ закалки иожей дл бумагорезательных машин, отличающийс тем, что придание ножам нужной формы и закалка их производ тс одновременно в чугунном штампе, состо щем из пуансона и матрицы, омываемых водой.The hardening method of the leather for paper shredding machines, characterized in that the knives are given the desired shape and hardened at the same time in a cast iron stamp consisting of a punch and a die, washed by water.
