Hydrodynamic lubrication of deep drawing
2020An isoviscous steady hydrodynamic lubrication model for a deep drawing process is developed. Equations to calculate lubricant film thickness, radial, and drawing stresses are presented. The die inlet film thickness is related to the properties of the lubricant and the sheet metal, the tooling geometry and the operating conditions.

International Deep Drawing Research
JOM, 1986The International Deep Drawing Research Group's (IDDRG) 14th Biennial Congress, which was held in Germany, attracted an international group of engineers and scientists involved in sheet metal forming and fabrication. Nearly 300 delegates and guests of 25 national groups participated.

This research work presents recent results on the formability of paper-based materials. Different kinds of commercial paperboard samples were evaluated using a laboratory 2D - formability tester, and a 3D deep-drawing equipment. It was found that the appearance of the formed shapes and the performance of paperboard in the forming process have a ...

Deep Drawing and Stretch Forming
1976Deep-drawing and stretch-forming processes make up a considerable proportion of metal-forming operations, and have deservedly received much attention. Although they are often thought of as mutually complementary, we should remember that whereas stretch forming may well be decisive in the success or failure of a deep-drawing process as a whole, it is an

Deep Drawing with Hydrodynamic Lubrication
1984A modified Deep Drawing process is proposed which eliminates dry friction by hydrodynamic flow. In principal, this process enables an increase in the Limit Drawing Ratio (LDR) by virtue of relaxing interfacial constrains. The fluid is enforced to lift up the blank from the die and to stream radially beneath it in a narrow gap.

The term metal forming refers to a group of manufacturing methods by which the given shape of a workpiece (a solid body) is converted to another shape without change in the mass or composition of the material of the workpiece. In this paper, the basics of a deep drawing process for the production of a thick plate steam boiler end caps are shown.
