MONOCON COLD FORGING PROCESSING METHOD AND MONOCON COLD FORGING

摘要

PURPOSE: a kind of single bore of cold forgeability is provided to maximization productivity and improves working environment, since the single gear wheel of cold forgeability can be reduced not only, but also productive hours extra charge. ;CONSTITUTION: a kind of manufacturing method of the single bullet of cold forgeability includes the following steps. Cut the material into regular length. Heating material is in 700& deg; C-800° C; It is impregnated 1 hour in keeping heating temperature; Adhere to that scheduled temperature and time is respectively step; It is passed through cooling (furnace is cold); By and also the 600& deg that is cool that annealed; C, the annealed material aerial photographing are handled in (SHOT) and standard Kuai Suwaiquqiu & Oslash; 0.6-Ø 0.8 millimeters of bullet times are 15-20 minutes. The completion of nonmetallic materials process of taking pictures is lubricated. Lubrication raw material is set up through combined forming process, including forward extrusion, backward extrusion, is carried out cold forging and is only bored (10) in inner circumferential surface list. ;The 2013 of copyright KIPO submissions;Sanction material in [Reference numerals] (AA) step; (BB) annealing and heating of step; (CC) step shooting is handled; (DD) lubrication in step; (EE) cold forging step
