Stamping Die Components: Types & Function

The stamping die usually has a fixed section and moveable sections. The fixed sections are made using clamp plate and screw to fixate them to the work table for the punch press, which called lower die. Moving sections will be rest on the slider of the punch press, also known as the upper die. To continue stamping, the upper die can be moved upwards and downwards using the slider.
The parts can be broken down into five different types based on their function.
Working components
The working progressive mold components are the elements that stamp work. They directly causing the sheet metal component deformation and separation, and then receive the stamping work piece. Like punch inserts, die inserts, punch-matrix etc.
Pilot components
Pilot components are used to regulate the direction of the raw material's feed and pitch, and make sure that the sheet of raw material is in the right stamping die location. Such as pilot pin, locating pin, guide pin, dowel pin, dowel plate, side clamp plate etc.
Components for material pressing, stripping, and lifting:
These components are used to make sure that the piece and scraps are removed from the tool following every stamping process. This helps in production when the next time comes around. For example: Stripper plate, lifting pin, scrap cutting inserts etc.
Guide components
These components ensure that the stamping dies are aligned in the right direction during relative movement. They also ensure that the punch and die inserts have a clear clearance. This increases the efficiency of the stamping parts.
Install and fix components
These press die components function are joined over four different stamping den components, in order to ensure that each tool part's relative positions are accurate and correct.
But, of course, that doesn't saying that every stamping die must contain more than five components for the die. When the stamping die is be used as a prototype or for small batch production, to reduce the time for validation and save cost, sometimes can be able to simplify the stamping design, which only has working components, stripping components and several fasten components.
Use of Different Stamping Die Components
1. Guide Plate Components
The primary function is to guide the strip of raw material to the correct location before inserting it into the tool. The strip should be parallel to the tool.
2. Punch and Die Components
These are the main components of a tool that can be used to cut and drilling, forming and bending.
For high precision and high volume projects, these inserts will be using carbide material which have high hardnessand can ensure the press die components precision and long-lasting life.
3. Stripper Plate Inserts
These components of the tool are placed inside the stripper plate. They are used to adjust tool settings and accuracy. There are 3 types of structure that include shoulder type, screw fix type, double layer type. The most commonly used type is shoulder type.
4. Pilot Pin and Mis-feeder Detection Device
Pilot pin's purpose is to make an adjustment strip before the tool 1 station starts to work. Mis-feeder can also prevent tool from closing if it is not feeding. This will help to safeguard the tool from injury.
5. Main Guide Pillar, Bush, Sub-guide Pillar and Bush. Bush Sub-guide Pillar, and Bush
Above stamping components, they All are standard components that are serve as tool guides. When working on stamping dies, usually will use the principal guide pillar and the post to create a first guide, then use the sub-guide pillar and the post to make precision guiding, which will guarantee the complete precision of the tool set.
6. Limit Bolt
This component is used to stop tool damage and die-closed height not being set correctly. It also provides protection for the inserts as well as tools.
7. Guide Pin
The guide pin can be used to guide material while it is being fed into molds. It is also used for material stripping.
8. Clamp Screw
The clamp screw serves to attach the die components to each other and provides a secure locking force to ensure that the tool is secure under pressure.
9. Connect the Screw
The plug screw usually together with the spring within the tool that can restrict spring's compression under force as well as adjust the precompression height of spring
10. Stripper Spring and Stripper Steer
The thread inside is utilized for the stripper screw. It can be used to fix stripper plates, and to disassemble them. In addition, the spring used to stripper mainly provide enough press force and stripping force for stripper plate.
