Die cutting and stamping machine (also known as die cutting machine, stamping machine) is a widely used equipment for precision cutting, stamping or forming of materials in the production process, commonly used in industries such as packaging, electronics, automotive, medical, etc. Its working principle is based on the action of molds and pressure, by placing materials in molds and using pressure to cut or shape them into predetermined shapes.
Working principle of die-cutting and punching machine
1. Equipment structure
The die-cutting and punching machine mainly consists of the following parts:
Upper and lower molds: The upper and lower molds are the core components of a die-cutting machine, where the upper mold is usually a metal plate with a cutting edge or embossed pattern, and the lower mold is the part that cooperates with the upper mold to form a cutting or forming space.
Pressure system: The die-cutting machine provides the necessary force for cutting and stamping through a hydraulic or mechanical pressure system. The pressure system transfers pressure to the upper mold, causing it to be applied to the material.
Conveyor system: used to feed materials to be cut or formed into the mold area, ensuring accurate alignment of the materials.
Control system: Modern die-cutting machines are usually equipped with PLC control systems or other automated control devices to regulate parameters such as pressure and speed.
2. Working process
The working process of die-cutting and punching machine can be divided into the following steps:
(1) Preparation stage
Mold installation: Install appropriate upper and lower molds according to the shape of the product to be cut or formed. The blade or embossed surface of the mold determines the shape and size of the finished product.
Material alignment: align the materials to be processed (such as paper, plastic film, foam, leather, etc.) and put them into the workbench or feeding system of the machine.
(2) Mold closure and cutting/forming
Upper mold descent: After starting the machine, the pressure system presses the upper mold down through hydraulic or mechanical means. The gap between the upper and lower molds forms a space that determines the cutting or forming contour based on the design shape of the mold.
Material cutting or forming: When the upper mold descends, the material is compressed inside the mold. For die-cutting machines, the mold has a sharp blade that cuts the material into specific shapes through pressure; For stamping machines, molds can be used for operations such as embossing, embossing, and concave convex forming.
Material detachment from mold: After cutting or forming is completed, the mold will quickly rise and detach from the material, allowing it to be smoothly removed or continue with the next step of operation.
(3) Repeat operation
Feeding and cutting: In the fully automatic die-cutting machine, the material is transported back to the mold area through the conveying system to complete the next cutting or forming. This process is repeated through automatic feeding, cutting, and recycling mechanisms.
3. Summary of the working principle of die-cutting and punching machine
The die-cutting and punching machine cuts, stamps, and shapes materials under pressure through the coordination of the upper and lower molds. When working, the mold cuts the material into the desired shape or performs embossing, embossing, and other treatments through precisely designed cutting edges or forming surfaces. The equipment provides necessary pressure through hydraulic or mechanical transmission systems to ensure machining accuracy and efficiency.
The main advantage of this device is its ability to efficiently and accurately process large quantities of materials, which are widely used in various industries such as packaging, electronics, and automotive.
