progressive die stamping
Progressive Die Stamping (Progressive Die Stamping/Continuous Die Stamping)
Progressive die stamping uses separate stations for various stamping operations including bending, stamping and cutting. The blank is fed into the progressive die, moves to the next station after each punch, and is ejected at the other end. Each station in a progressive die is different from the previous one, and the results are often more precise than with other types of stamping operations.

Progressive Die Stamping
Electric tools, accessories, electric tool accessories; electric appliance parts; hydraulic machinery accessories; other: pneumatic accessories and hydraulic accessories. Due to the different working principles of stamping machines, the types of molds used are also different. According to the processing method, it can be divided into three categories: manual presses (high pressure workpieces are pressed into high precision), mechanical presses and hydraulic presses. According to the function, it can be divided into: blanking parts, drawing parts and stamping plates.
1. The material of the stamping parts should be consistent with the working principle of the stamping machine, and there should be no defects such as deformation and cracking.
In general, the material can work directly with the punching machine after processing. During use, it is necessary to conduct a punching test to determine whether the stamping material meets the working principle and processing requirements of the punching machine. During the punching test, attention should be paid to the stress distribution and deformation existing in the mold to ensure the punching accuracy and dimensional accuracy. When a blanking part has one of the following defects, the stamping test shall not be carried out: the first defect is internal stress; the second defect is deformation; the fourth defect is thickness deviation; the fifth defect is external dimension deviation; the sixth defect is the change of material and process parameters; Defect seven is machining allowance, punching width deviation and length deviation, etc. According to the blanking method and equipment requirements, the performance of the materials used shall be determined through tests if possible. It can be used only after passing the inspection.
2. The material of stamping parts should be hard metal of cold-rolled steel plate, stainless steel plate and carbon steel.
The appearance of stamping parts should be flat and smooth, without bumps, cracks and deformation, and without burrs. Choose the appropriate material according to the actual situation. Do not stamp parts with iron, aluminum, copper, stainless steel and other materials.

3. The mold should be made of oil-resistant and corrosion-resistant materials, and the surface must be polished.
The mold should have good working performance and sufficient strength, structural strength and service life. The mold surface should be firm without wear and deformation. Die faces should be firmly bonded together. The interior of the mold should be kept clean, dry and free from water and oil stains. The mold should also have sufficient strength, good modulus of elasticity and deformation capacity commensurate with the strength.
4. Punching parts and drawing parts are a kind of processing tool like punching dies. To use it correctly, you need to understand its scope of application and working principle, such as whether the pressing material is flexible and flexible, and the size of punching parts and drawing parts Whether the accuracy is qualified, etc.
With the continuous improvement of people’s living standards, people’s quality of life is also constantly improving, and at the same time people are paying more and more attention to environmental protection, so in our daily life, there will be strict requirements for our daily behavior. Therefore, we will be required to take corresponding measures to protect our health when we need to take protective measures for some inedible foods in our lives. So now let me introduce to you what you should pay attention to when you can’t eat it in your daily life but you need to take protective measures yourself. For some daily necessities that need to be prevented and handled by themselves, people can pay great attention when they produce and need to make them, which can effectively protect people’s health.
5. Choose the correct blanking tools and production process to ensure the quality and efficiency of blanking.
In the surface treatment process of blanking parts, the punching tool is required to have sufficient rigidity, good rigidity and sufficient surface roughness to ensure that the workpiece can be punched smoothly. And this is also the key to choosing the right punching tool and punching process that plays a decisive role in the final quality of the punched part. Since its main function is to form and bend, it is very important to choose the correct punching tool and production process to ensure the quality and efficiency of punched parts. When selecting punched parts, try to avoid flat punching, flat bending, arc bending, etc. that are difficult to punch. Different types of blanking parts and stamping parts of different shapes should be selected according to different process conditions to ensure production cost and production efficiency; at the same time, attention should also be paid to the quality and accuracy of punching to avoid damage to part accuracy due to oversized or undersized punching. The higher the processing accuracy, the better; therefore, according to your different needs, you should choose blanking parts that are suitable for your own production process or suitable for your product shape and performance characteristics.
