Three-way contact leaf sheet metal punching multi-station progressive die
The three-way contact leaf sheet metal punching multistation progressive die refers to a device used to mass-produce multiple parts that are shaped by cutting out and pressing high in a single equipment. This type of die is composed of a single die body and multiple strips that form a particular shape. The single piece of equipment can cut, bend borders, form holes and other shapes. Its characteristics are:
1. The die design standard is higher, and the number of blades used for processing the same parts is relatively small, which can save the cost of materials and processing;
2. It has a fast production speed, can be used for mass production and continuous production, and can save labor costs;
3. The size of the parts produced is accurate, and the stamping process is highly automated;
4. The production line is short and the layout is reasonable, which can effectively reduce the floor area of the production workshop;
5. Higher production quality, uniform production specifications and easy maintenance.
The structure of a three-way contact leaf sheet metal punching poly-station progressive die mainly includes two parts: a fixed part and a movable part, and the two parts of the die are generally made of high-strength tool steel, and both are heat-treated to selectively improve the hardenability, wear resistance and toughness. The fixed part of the die has a strip feeding mechanism and a stripper, and the strip is cut into a certain shape by the cutting member. The moving part of the die has a punch, a pressure receiving sheet, a die punch and a die punch sleeve. There are also many small parts, such as guide pins, guide bushes, locating pieces, etc.
The three-way contact leaf sheet metal punching poly-station progressive die is composed of a series of processes that are linked together. When the stripping action occurs, the first station will stamp out a blank shape with a punch. The shaped blank proceeds through the die cutting surface of each station and the pressure-receiving sheet until the cutting is completed and the shaped part is finished. Then, the blank enters the ejection station, which pushes the shaped part out of the die frame with an ejector pin.
In a three-way contact leaf sheet metal punching poly-station progressive die, each station of the die must perform a specific function and interact with adjacent parts to complete the entire stamping process. The design of the die must ensure that the part is accurately stamped, compensated for surface shrinkage, has sufficient support, and can effectively support the part to ensure the quality of the part.
In the stamping process using a three-way contact leaf sheet metal multistation progressive die, the blank constantly pushes forward, and after the stamping function of each station is completed, the empty part will move to the next station without the need of external force. After being tracked and supported after each station, the product can be centered and aligned to ensure that the materials in different positions have uniform shrinkage.
In short, compared with traditional stamping dies, three-way contact leaf sheet metal multi-station progressive dies have higher production efficiency and quality, and can achieve continuous production of complete parts with high precision, which is of great significance to improving production efficiency and reducing production costs.
