Investigation on the optimal geometrical parameters for cylindrical cups in warm hydromechanical deep drawing process [PDF]

2017 8th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2017
Warm sheet hydroforming process has being investigated in recent years with its high formability feature. Warm hydromechanical deep drawing (WHDD) which is a type of the warm sheet hydroforming process is important for deeper parts. To determine the formability of the WHDD process the most convenient tool is Limiting Drawing Ratio (LDR).

COMPARISON OF CONVENTIONAL DRAWING, INVERTED DRAWING AND WARM FORMING PROCESSES FOR DEEP DRAWING OF ALUMINIUM CUPS [PDF]

International Journal of Mechanical and Industrial Engineering, 2014
Cup drawing is one of the important operations in sheet metal forming. Manufacturing of the aluminium base cup involves several stages such as blanking, first drawing, second drawing, taper formation and trimming. This increases the process time. An attempt has therefore, been made to develop a comprehensive, rigorous, yet easily-workable method of ...

Warm deep drawing of aluminium sheet [PDF]

, 2003
Aluminium sheet drawing processes can be improved by manipulating local flow behaviour by means of elevated temperatures and temperature gradients in the tooling. Forming tests showed that a substantial improvement is possible not only for 5xxx but also for 6xxx series alloys.

Numerical optimization of warm hydromechanical deep drawing process parameters and its experimental verification

Journal of Manufacturing Processes, 2020
Abstract Warm Hydromechanical Deep Drawing (WHDD) is considered as an effective sheet metal forming process to overcome low formability problems of lightweight materials, such as aluminum and magnesium alloys, at room temperature. WHDD process combines the advantages of Hydromechanical Deep Drawing (HDD) and Warm Deep Drawing (WDD) processes. In this

"Set for Two Variation#2" (Drawing Biennial 2021, Drawing Room, London) [PDF]

, 2021
This work is part of a series of drawings which inform my larger scale painting. The drawing and re-drawing of shapes from observation and memory allow me to rediscover and develop spaces and form within the pictorial space. I allow space in the work for

Deep Drawing Behaviour of Steel–Glass Fibre-Reinforced and Non-Reinforced Polyamide–Steel Sandwich Materials

Applied Sciences, 2023
Thermoplastic-based fibre metal laminates (FMLs) have gained increasing interest in the automotive industry due to their forming potential—especially at higher temperatures—into complex components compared to thermoset-based ones.

Deep drawing of DC06 at high strain rates

, 2023
Velocity effects in production technology provide technological and economic advantages, but they require consideration of strain rate dependent material behaviour in numerical process modelling.

Two step–ageing of 7xxx series alloys with an intermediate warm-forming step

Journal of Materials Research and Technology, 2021
Two-step ageing of 7xxx series alloys can reduce ageing time while obtaining similar mechanical properties as a longer isothermal heat treatment. In this paper, an intermediate deep-drawing step at 120–160 °C is introduced to produce elongated cup–shaped

Formability studies of ASS 304 and evaluation of friction for Al in deep drawing setup at elevated temperatures using LS-DYNA

Journal of King Saud University: Engineering Sciences, 2014
Deep drawing is a sheet metal forming operation which involves conversion of flat thin sheet blanks drawn into desired cups. Forming of high strength sheet metal and low weight alloys under warm conditions is in great demand now-a-days and its ...

Robot-Assisted Cold and Warm Incremental Sheet Forming of Aluminum Alloy 6061: A Comparative Study

Metals, 2023
Incremental sheet forming (ISF) requires no or partial dies for sheet metal fabrication and is widely used for small batch production. In this process, necking is either suppressed or delayed due to the localized nature of tool–sheet contact; hence, more
