A die is a specialized machine tool used in manufacturing industries to cut and/or form material to a desired shape or profile. Stamping dies are used with a press, [1] as opposed to drawing dies (used in the manufacture of wire) and casting dies (used in molding) which are not.

2005年6月14日 · Most forming operations involve at least two basic components: a punch, representing the male portion of the die, and the cavity, representing the female portion. Although many die types exist, this article focuses on those used in the most common forming operations. Embossing dies use tension to stretch metal into a shallow depression.

模具是在材料处于固态状态下，通过施加压力进行成型的关键工具，通常由上模（Upper Die）和下模（Lower Die）组成。 如下图，是锻造模具，金属在高温下具有了可塑性，金属被置于模具之间，然后受到压力和冲击，就变成了特点形状。

2006年8月8日 · A stamping die is a special, one-of-a-kind precision tool that cuts and forms sheet metal into a desired shape or profile. Most dies are constructed of several basic components, including die plates, shoes, die sets, guide pins, bushings, heel blocks, heel plates, screws, dowels, and keys.

Die forming typically occurs immediately after polymer melt has exited an extruder. The most basic process involves guiding the stream of molten polymer under pressure through a die, which three distinct regions: manifold, approach, and lip.

Open die forging (Also called "upsetting" or "upset forging"): Basically reduced height & increases width of workpiece. Dies are flat & no precise control over shape. 开模锻造（也称为“镦粗”或“镦锻”）。 基本上减小了高度并增加了工件的宽度。 模具是扁平的，没有精确的形状控制。

Today, thousands of makers are making their own dies and using a hydraulic press. Getting the most out of die forming process requires skill in die making and knowledge of how the press can be utilized.

2024年5月21日 · A die is a metal (or other hard material) mold or tool that is used to shape, cut, or form materials into desired shapes and sizes. Die making is a highly skilled and technical field that requires knowledge of materials science, engineering principles, …

Die forming is a widespread sheet metal forming manufacturing process. The workpiece, usually a metal sheet, is permanently reshaped around a die through plastic deformation by forming and drawing processes. Simulations can be carried out in order to avoid cracks, tears, wrinkles, too much thinning, and stretching.

2008年1月15日 · There are numerous types of forming dies. Some of the most common forming die types are bending, stretching, flanging, drawing, coining, extruding, and ironing. 1. Bending. Bending can be defined as a forming operation in which the metal is deformed along a straight axis. Tabs and channels are formed using the bending process. 2. Stretching.
