Analysis of temperature and speed effects on the drawing stress for improving the wire drawing process

Materials & Design, 2011
This paper deals with experimental investigations in order to study the influence of drawing conditions on temperature rise and drawing stress in cold drawn copper wires. In the multipass drawing machine, the temperature rise and drawing stress are measured with thermocouples and load cell systems, respectively, for different drawing speeds.

High-speed drawing of optical fibers with pressurized coating

Journal of Lightwave Technology, 1985
To make progress in high-speed drawing of optical fibers, a pressurized coating method was developed on the basis of viscous flow behavior of the coating resin. In a pressurized die, when the shear rate at the fiber surface is minimized, the pressure which is affected by the resin viscosity reaches on optimum condition, resulting in the coating ...

Prevention of Partial Draw-In During High Speed Deep Drawing

Key Engineering Materials, 2009
Due to an ongoing trend of function compaction miniaturization gets more and more important in industrial production. Through the growing miniaturization new difficulties have overcome like scaling effects. However, on the other hand scaling towards smaller parts enables the application of new technologies which do not work in macro engineering.

Edge Detection in Natural Scenes Inspired by the Speed Drawing Challenge

International Journal of Image and Graphics, 2021
Edge detection is a major step in several computer vision applications. Edges define the shape of objects to be used in a recognition system, for example. In this work, we introduce an approach to edge detection inspired by a challenge for artists: the Speed Drawing Challenge.

Lubricating and cooling liquids for high-speed drawing

Vestnik Mashinostroeniya, 2022
The features of the effect of the lubricating-cooling liquid (LCL) on the cutting process during high-speed drawing of the external shaped surfaces are considered. Criteria and recommendations for the selection of coolants for highspeed drawing of workpieces from structural steels are given.

High-speed drawing of steel wire

Steel in Translation, 2013
The increase in productivity due to increase in the drawing speed may be largely lost as a result of more frequent shutdown of the equipment associated with the replacement of worn dies and with wire fracture. The influence of the tool parameters on its wear and the wire fracture is analyzed.

Speed Up Graph Drawing for Social Network Visualization

2011
Though classical forced-directed algorithms have many advantages on graph drawing, such as good-quality results, flexibility, simplicity, etc., the high running time makes them impractical to real applications. To this end, we propose a community-based approach to speed up graph drawing for social networks under the assumption that the position of a ...

Predicting fracture in high-speed wire drawing

Strength of Materials, 1981
1. A mathematical model of wire drawing speed was constructed, with allowance for inertial terms and the angle of taper, from the theory of viscoplastic flow. The stresses and temperature inside the deformation zone were determined. 2. The model makes it possible to find the critical drawing speeds corresponding to brittle and ductile ...

Adjustable speed D-C drives for deep-draw presses

Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1953
The trend in the automobile industry toward larger and more complex stamped parts for fabricating automobile bodies has necessitated radical changes in the design of stamping presses and their associated drives. The drive problems presented by these more complex machines and operations have led to the development of new drive systems.
