Description

Technical Field

[0001] This utility model relates to the field of steel stamping technology, and in particular to a steel stamping assembly with quick mold change capability. Background Technology

[0002] Steel is a material with a certain shape, size and properties made from steel ingots, billets or steel through pressure processing. Steel stamping components are a type of equipment used to stamp steel, which applies pressure to cause plastic deformation of the steel, thereby obtaining parts or products with the required shape and size.

[0003] Most existing stamping components use fixed dies. Due to the inconvenience of disassembly and replacement, they can only produce one or a few specific shapes and sizes of stamped parts, which cannot meet the market's demand for diversified products. As production continues, the dies will gradually wear out. If the worn dies cannot be replaced in time, the dimensional accuracy and surface quality of the stamped parts may decline, affecting the overall quality and performance of the products. Long-term use of worn dies may also lead to an increase in scrap rate.

[0004] Therefore, since most of the existing stamping components use fixed molds, which are inconvenient to disassemble and replace, they may not be able to meet the market's demand for diversified products. Furthermore, with prolonged use, the molds will gradually wear down, affecting the overall quality and performance of the products. It is possible to design steel stamping components with quick mold replacement, which can replace the molds as needed, facilitating production while maintaining the overall quality and performance of the products.
