Stamping dies are the tools that shape and cut sheet metal parts. They are commonly developed using computer-aided design (CAD) software and analytical programs to create and prove-out highly accurate, unambiguous designs. These designs are then translated into stamping dies by skilled craftsmen, known as diemakers. Once these stamping dies are mounted into presses, sheet metal is fed to them to produce parts. Dies contain cutting and forming sections that are usually made from special hardenable steel, known as tool steel.
These cutting and forming sections can also be made from different hard wear-resistant materials, like carbide. Stamping is a cold-forming process, in which heat is neither used on purpose into the die nor the sheet. However, since the cutting and forming process entails friction, which in turn generates heat, stamped parts that leave the dies are often very hot. Dies used in making microelectronics are available in a variety of sizes, some small enough to fit your palm, while others can reach 20 square ft by 10-ft.
The installation of hardware stamping die is very important. No matter how good the quality of the mold is, it will also cause many production problems through the wrong method of installation. Facts have proved that the wrong installation of the stamping die will not only affect the quality and accuracy of the stamping parts, but also reduce the service life of the die. In serious cases, production accidents will occur. Therefore, the installation of the stamping die is a point that the stamping factory needs to attach great importance to. Next, we will analyze how to correctly install the stamping die.
A1. Open the workbench and clean it up
Clean the worktable guide rails before opening, clean up waste and other debris, check whether there are items on both sides of the mold table that are over-wide, to prevent interference with the main column of the press when the worktable is opened, and cause accidents. The stop position of the workbench should be reasonable, with square hanging mold and mold placing as the standard, but a certain safety distance should be kept from the block of the guide rail;
A2. Install the ejector rod according to the “Operation Instructions” and ensure that the ejector rod length is consistent
Select the ejector pin and ejector position according to the ejector pin diagram in the “Operation Instructions”. After placing the ejector pin, check to ensure the consistency of the ejector pin position and length. In order to make the mold placement position accurate, follow In the instruction book, place positioning pins on the corresponding positions of the mold. In addition, the cover plate of the ejector hole should be placed in a fixed position to prevent loss;
A3. Lift the mold on the worktable and align the center with the worktable center of the press
Clean the bottom and upper surface of the mold before placing the mold. After the mold is placed, check the alignment of the installation grooves with the T-shaped groove of the press to facilitate installation;
A4. The worktable is opened and clamped
Clean the base of the press before the workbench is moved in. When the workbench is moved in, it must be opened in place before it can be dropped and clamped;
