Cover die making
1. Drawing die
Drawing die is the most important equipment to ensure that qualified covering parts are made. Its function is to shape the flat wool into a three-dimensional space workpiece through a drawing process.
Drawing dies are available in two types, formal and inverted. The front-loading drawing die and the punch and the blanking ring are on the top, and the female die is on the bottom. It uses a double-action press. The punch is installed on the inner slide block and the blanking ring is installed on the outer slide block. The outer slide block goes down first when forming. , The press ring presses the wool tightly on the surface of the die, and then the inner slide moves down, the punch extends the wool into the cavity of the die, and the wool undergoes large plastic deformation under the action of the punch, the die and the press ring . The punch and press ring of the upside-down drawing die are on the bottom, and the die is on the top. It uses a single-action press. The punch is directly mounted on the lower worktable. The press ring uses the ejection cylinder under the press to pass the top. The rod obtains the required pressing force. Flip-chip drawing dies can only be used when the ejection pressure can meet the pressing requirements.
2, trimming die
The trimming die is used to remove the extra material of the process supplementary part of the drawn part and the blanking flange to prepare conditions for flanging and shaping. In small batch production, manual and other simple equipment can be used instead. Trimming of the trimming die is often combined with punching.
When trimming the edges, the trimming mold should cut the waste into several sections, each of which is between 200 and 300mm in length. The separated waste is easy to pack and transport.
3. Flanging die
Flanging die is to flip part of the material of the semi-finished workpiece relative to another part of the material. According to the different punching direction of the flanging, the flanging die can be divided into two categories: vertical flanging die and horizontal flanging die. Horizontal flanging (including inclined flanging) requires an oblique wedge structure to complete the flanging forming work. Fanbian molds are also necessary equipment to make qualified covers.
