sügavtõmbamist

Sügavtõmbamine is an Estonian term referring to a metal forming process known as deep drawing in English. It is a manufacturing technique used to shape sheet metal into a desired three-dimensional form, typically a hollow shape like a cup, can, or complex car body panel.

The process involves drawing a flat sheet of metal, often called a blank, into a die cavity using a punch. The punch exerts force on the blank, pushing it through the die opening. This stretching and thinning of the metal allows it to conform to the shape of the die. Key elements in deep drawing include the blank holder, which applies pressure to prevent wrinkling of the metal sheet, and the die and punch, which define the final shape.

Deep drawing is widely used in various industries due to its ability to produce complex shapes with high precision and good surface finish. It is common in the production of kitchenware, automotive parts, ammunition casings, and packaging. The success of the deep drawing process depends on factors such as the material's ductility, the tool design, the lubrication used, and the precise control of forces and speeds involved. Different variations of deep drawing exist, including single-action, double-action, and triple-action drawing, each suited for specific applications and complexities.
