冲压件与铸件、锻件相比,具有薄、匀、轻、强的特点。冲压可制出其他方法难于制造的带有加强筋、肋、起伏或翻边的工件,以提高其刚性。由于采用精密模具,工件精度可达微米级,且重复精度高、规格一致,可以冲压出孔窝、凸台等。
Compared
with castings and forgings, stamped parts have the characteristics of
being thin, uniform, light, and strong. Stamping can produce workpieces
with reinforcing ribs, ribs, undulations or flanges that are difficult
to manufacture by other methods, in order to improve their rigidity. Due
to the use of precision molds, the workpiece accuracy can reach the
micrometer level, with high repeatability and consistent specifications,
and can be stamped with holes, protrusions, etc.

Stamping machine
冲压件机器冷冲压件一般不再经切削加工,或仅需要少量的切削加工。热冲压件精度和表面状态低于冷冲压件,但仍优于铸件、锻件,切削加工量少。
Stamping
machine cold stamping parts generally do not undergo cutting
processing, or only require a small amount of cutting processing. The
accuracy and surface condition of hot stamping parts are lower than
those of cold stamping parts, but still better than castings and
forgings, with less cutting processing.
冲压是高效的生产方法,采用复合模,尤其是多工位级进模,可在一台压力机上完成多道冲压工序,实现由带料开卷、矫平、冲裁到成形、精整的全自动生产。生产效率高,劳动条件好,生产成本低,一般每分钟可生产数百件。
Stamping
is an efficient production method that uses composite molds, especially
multi-station progressive molds, to complete multiple stamping
processes on a single press, achieving fully automatic production from
strip uncoiling, leveling, punching to forming and finishing. High
production efficiency, good working conditions, low production costs,
generally capable of producing hundreds of pieces per minute.
冲压主要是按工艺分类,可分为分离工序和成形工序两大类。分离工序也称冲裁,其目的是使冲压件沿一定轮廓线从板料上分离
Stamping
is mainly classified by process and can be divided into two categories:
separation process and forming process. The separation process, also
known as punching, aims to separate the stamped part from the sheet
metal along a certain contour line
