20.500.12556/RUL-159948 The double-sided upsetting of the end thickenings on rod blanks Dvostransko krčenje odebelitev na koncih paličastih surovcev The known methods for the plastic shaping of axisymmetric parts with bilateral end thickenings and the die equipment used for their application have several significant drawbacks, which may reduce the quality of manufactured products, increase their cost, and limit the technological capabilities of production. As a rule, they provide alternate plastic shaping of end thickenings. In this paper, we propose a method of simultaneous stamping of end thickenings on a bar stock in split dies and a stamping device for its implementation. To establish the power modes of stamping we carried out the simulation of the process under study using the finite element method in the QForm software package. The dependencies of the stamping force on the geometric dimensions of the workpiece and friction conditions on the contact surfaces are established. The damageability of the workpiece material made of AA5056 alloy was assessed, and a diagram was obtained to determine the number of required stamping operations. cold forging upsetting end thickenings force material damageability hladno kovanje krčenje odebelitev na koncih sila podvrženost materiala poškodbam true false true Angleški jezik Slovenski jezik Članek v reviji 2024-08-01 07:58:35 2024-08-01 07:58:39 2024-08-02 04:01:19 0000-00-00 00:00:00 2024 0 0 8 str. no. 5/6 Vol. 70 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.73 0039-2480 10.5545/sv-jme.2023.550 201995779 The_Double-Sided_Upsetting_of_the_End_Thickenings_on_Rod_Blanks.pdf The_Double-Sided_Upsetting_of_the_End_Thickenings_on_Rod_Blanks.pdf 1 771B897F4156110E19EB6F1FDE6EF7ED c545301cd8a6f6a4d1afd828c2af3f365ae7636cb88162f365b3eaa6ea1508eb b6359568-4fcb-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188201 https://www.sv-jme.eu/sl/article/double-sided-upsetting-of-end-thickenings-on-rod-blanks/ 1 fcd5fc04-4fca-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188200 Fakulteta za strojništvo Strojniški vestnik 0 0 0
