Common forming type 'hardware' for drawing processing of precision stamping parts

The use of stamping equipment for drawing and forming of precision stamping parts, including: drawing processing, re-drawing processing, reverse drawing and thinning drawing processing, etc. Drawing processing of precision stamping parts: using a platen device and using the punching force of a punch to pull part or all of the flat material into the cavity of the concave mold to form it into a container with a bottom. The processing in which the side wall of the container is parallel to the stretching direction is a simple stretching processing, while the stretching processing of conical (or pyramidal)-shaped containers, hemispherical containers, and parabolic surface containers also includes expansion processing. Re-precision stamping parts drawing processing: that is, for deep drawn products that cannot be completed in one drawing process, the drawn formed products need to be drawn again to increase the depth of the formed container. Reverse drawing of precision stamping parts: Reverse drawing of the drawn workpiece in the previous process, the inner side of the workpiece becomes the outer side, and the outer diameter of the workpiece is reduced. Stretching of thinning precision stamping parts: Use a punch to squeeze the formed container into a concave mold cavity that is slightly smaller than the outer diameter of the container, so that the outer diameter of the bottomed container is reduced, and the wall thickness is thinned at the same time, which removes the wall thickness. Deviations make the surface of the container smooth.
