Optimization of Flash, Billet Dimensions and Friction Factor in Closed Die Cold Forging Process
Three important parameters in designing a closed die for forging process are ratio of width to flash thickness, ratio of height to billet diameter and the friction factor. In this paper the influences of these parameters on the required force for the forging and percentage of die filling were investigated. It was found that by controlling the flash dimension, the material loss is reduced and t...
متن کاملEffect of friction stir welding parameters on the ultimate tensile strength of Al-Cu tailor welded blanks
In the present study, parameters of tool rotation speed, tool travel speed and tool offsetting with different levels were used in the friction stir welding (FSW) of aluminum-copper tailor welded blanks (TWBs). The FSW of pure copper to 5052 aluminum alloy were carried out by varying tool rotation speed from 800 rpm to 1200 rpm, tool travel speed from 40 mm/min to 80 mm/min and tool offsetting f...
متن کاملFinite element analysis of tailor-welded blanks
A typical tailor-welded blank (TWB) is composed of several base metals, which might have di!erent mechanical properties as well as thickness. Moreover, a TWB contains a heat-a!ected zone (HAZ) which has quite di!erent mechanical properties from base materials. The forming behaviors of TWBs have been widely studied since they were "rst developed as a way of using collectible o!al. They are often...
متن کاملThe Strength of Friction Stir Welded and Friction Stir Processed Aluminium Alloys
Local strength of friction stir (FS) welds and FS processed aluminium alloys in heat treatable aluminium alloys is dominated by precipitation hardening. Strengthening due to stored dislocations is generally limited to 40MPa, and grain size strengthening is generally less than 10MPa. Local crystallographic texture can cause yield strength variation on the order of 5%. Published models for streng...
متن کاملOptimum Designing of Forging Preform Die for the H-shaped Parts Using Backward Deformation Method and Neural Networks Algorithm
In a closed die forging process, it is impossible to form complex shapes in one stage, and thus it becomes necessary to use preform dies. In the present study, Backward Deformation Method and FE simulation via ABAQUS software has been used in order to design preform die of the H-shaped parts. In the Backward Deformation Method, the final shape of the part is considered as a starting point and u...
