The application of stamping machines for metal stamping parts to carry out stretching and forming processing of goods, including stretching processing, re stretching processing, reverse stretching and thinning stretching processing, etc.
Hardware stamping processing applies stamping machine tools to carry out stretching and forming processing of goods, including stretching processing, re stretching processing, reverse stretching and thinning stretching processing, etc.
Stretch processing: Using pin equipment and the punching working pressure of the mold base, a part or all of the flat material is pulled into the cavity of the concave solid model to form a container with a bottom. The processing of the parallel surface between the outer wall of the container and the stretching direction is a simple stretching processing, while the stretching processing of cone (or pyramid) descriptors, cylindrical containers and Hyperbola containers also includes expanding processing.
Hardware production processing and re stretching processing: For deep stretching products that cannot be processed in one stretching process, the formed products must be re stretched to enhance the depth of the formed container.
Reverse stretching processing: The process of stretching the stretched product workpiece in the previous process in the opposite direction, turning the inner side of the product workpiece into two sides and reducing its diameter.
Thinning and stretching processing: Use a mold base to squeeze the formed container into a concave solid model cavity slightly smaller than the container diameter, reducing the diameter of the container with a bottom, while thinning the wall thickness. This not only eliminates wall thickness errors, but also makes the surface of the container smooth and clean.
