CNC Stamping Service
CNC Stamping is a method of metal cold deformation processing. So, it is called cold stamping or sheet metal stamping, abbreviated as stamping. It is one of the main methods of metal plastic processing (or pressure processing), and also belongs to material forming engineering technology.
Stamping process as an efficient and accurate all-metal processing method, It has a wide range of application prospects in the manufacturing industry.Understand and master the punch the basic knowledge of the pressing process is important for improving product quality and reducing production.It is of great significance to increase production costs and enhance the competitiveness of enterprises.
In practical applications, it needs to be based on the requirements and process conditions of specific parts. reasonable selection of equipment, materials and process parameters, and effective Process control and quality inspection to ensure the key links of the stamping process
Advantage of CNC Stamping
CNC Stamping, also known as Computer Numerical Control (CNC) Stamping, is a modern manufacturing process that combines the precision and automation of CNC technology with the speed and efficiency of traditional stamping operations.
Precision and Accuracy
CNC stamping machines use computer-controlled positioning systems to precisely control the movement and positioning of the stamping tools.
Increased Productivity
The automated nature of CNC stamping allows for faster cycle times and higher production rates compared to manual or semi-automated stamping processes.
Flexibility and Adaptability
CNC stamping machines can be programmed to perform a wide range of stamping operations, including punching, blanking, forming, and embossing.
Improved Consistency and Quality
The precise control provided by CNC stamping ensures consistent part quality, with minimal variations in dimensions, surface finish, and overall part integrity.
Reduced Waste and Environmental Impact
The ability to precisely control material usage and tool movements helps to reduce the environmental footprint of the manufacturing operation.
Enhanced Safety
CNC stamping machines often incorporate advanced safety features, such as sensor-based guarding and emergency stop mechanisms, which help to protect operators and minimize the risk of workplace injuries.
Stamping Press
The stamping press presses the top and bottom dies together with force and accuracy that deforms the metal by forming, drawing, trimming, blanking or piercing the metal.
Metal stamping refers to the use of punches and dies to deform or break stainless steel, iron, aluminum, copper, and other plates and heterosexual materials to achieve a certain shape and size. It involves the stretch and blanking process of the metal plate in two or three dimensions. The process can also use perforation and other operations
Common Technical Terms for Metal Stamping Parts
Stamping is mainly classified according to the process, which can be divided into two categories: separation process and forming process.The separation process is also called blanking. Its purpose is to separate the stamped parts from the sheet material along a certain contour line, while ensuring the quality requirements of the separation section.The purpose of the forming process is to plasticize the sheet material without breaking the blank to make a workpiece of the desired shape and size.In actual production, multiple processes are often applied to one workpiece in a comprehensive manner.
1. Deep drawing: A stamping process in which raw steel or process parts are changed into hollow parts or the shape and size of hollow parts are further changed. During deep drawing, the hollow part is mainly formed by the flow of material outside the bottom of the punch into the die.
2. Trimming: A stamping process in which the edge of the forming process is trimmed with a metal stamping die to have a certain diameter, a certain height, or a certain shape.
3. Punching: A punching process in which the waste is separated from the material or process piece along the closed contour, and the required hole is obtained in the material or workpiece.
4. Flanging: A stamping process in which the material is turned into a short side standing on the side along the contour curve.
5. Flipping hole: A stamping process in which the material is turned into a side flange along the circumference of the inner hole.
6. Blanking: A stamping process that separates materials along a closed contour. The separated material becomes a workpiece or process piece, most of which are flat.
7. Shaping: a stamping process that relies on the flow of materials to change the shape and size of the process parts in a small amount to ensure the accuracy of the workpiece.
CNC Stamping is a relatively cheap and fast method of production compared to machining. When speed is the most critical consideration, metal stamping is the first choice. But when complex or high-precision shapes are required, CNC machining is more beneficial.
Basic knowledge of Stamping Process
Design of Stamping Die
Stamping die is a key component in the stamping process, and its design quality It directly affects the shape, size and accuracy of the product.Mold design
The geometry, material properties, and stamping force of the parts need to be considered，Mold material and other factors.Reasonable mold design can improve production Efficiency, reduce the scrap rate, and extend the service life of the mold.
Structure of Metal Stamping Die
The stamping die is the core tool of the stamping process, usually composed of a punch、
It consists of a concave mold, a discharge device, a guide device, etc.The punch is responsible for the material is pressed into the concave mold to form the desired shape; the concave mold defines The final shape of the part; the unloading device is responsible for the stamping of the finished parts the parts are removed from the mold; the guide device ensures that the punch and die are in the relative position in the stamping process is accurate.
Selection of Stamping Materials
The choice of stamping materials directly affects the quality, performance and production of parts Production efficiency.Commonly used medium pressure materials include mild steel and stainless steel. Aluminum alloy, etc.When choosing materials, you need to consider the plasticity of the materials factors such as sex, strength, toughness, surface quality, and cost.
Control of Stamping Quality
Stamping quality control is to ensure stable part quality and improve production efficiency the key link of the rate.Common quality control methods include material inspection Inspection, mold debugging, process parameter optimization, dimensional measurement, etc.same as At the same time, it is also necessary to strengthen staff training and improve operational skills and quality.Awareness, to ensure that each I-shaped word meets the process requirements.
Safety and environmental protection
In the medium pressure process, safety operating procedures must be strictly observed to ensure ensure the safety of employees and equipment.Necessary safety protective clothing should be provided settings, such as protective barriers, safety doors, etc., to prevent operators from straying into danger dangerous area.In addition, we also need to pay attention to environmental protection requirements and deal with them rationally.
Waste and wastewater generated in the stamping process reduce environmental pollution
dye.
Conclusion of CNC Stamping
The stamping process is an important part of the modern manufacturing industry and has life. The advantages of high production efficiency and high accuracy.Through continuous learning and practice, the technical level and application capabilities of stamping technology can be continuously improved, and contributions can be made to the development of manufacturing industry.
