A New Type Heat Treatment Equipment for H13 Mandrel

摘要: H13芯棒新型熱處理設(shè)備將對(duì)開(kāi)鐘罩式電阻加熱爐與專用的淬火起重機(jī)及夾吊具有機(jī)地結(jié)合在一起,為長(zhǎng)軸類工件的淬火提供了一種全新的裝置。介紹了從熱處理爐密封與功率匹配方面入手,解決了大型熱處理爐的溫度均勻性問(wèn)題;從工件裝出料方式及PLC控制系統(tǒng)方面入手,確保了長(zhǎng)軸類工件在臥式加熱淬火過(guò)程中實(shí)現(xiàn)自動(dòng)控制及變形量最小,從而提高了芯棒的熱處理質(zhì)量。

Abstract: The new type heat treatment equipment for H13 mandrel is used together with the split bell resistance heating furnace,and the special lifter and the tackle for quench operation,being a completely different vehicle for quenching long shaft pieces. Elaborated here in the article is the solution of the problem related to temperature homogeneity of big heat treatment furnace via appropriate sealing of the furnace and proper power allocation. Thanks to the proper type of piece charging/discharging and the PLC control system,it is ensured that the long shaft piece is well automatically controlled with little deformation,when quenched horizontally,and thus heat treatment quality of the mandrel is improved.
