Punch knowledge

With the development of society, from the statement that punching machines are AIDA in the 1960s to hundreds of brands of punching machines today, we have experienced reform and development again and again, the industrialization of specifications and models has been refined, and special stamping equipment has appeared in all walks of life. Let's start with the smallest and simplest!

First, the hand press, which we call the hand press, is mainly used in small riveting industries, such as shoe factories, zipper factories, hardware products and so on! The general pressure is around 100 kg! The function is clumsy, cheap and affordable!

Secondly, the desktop precision punch is also the evolution of the hand press. I think so, too. Generally, the pressure is around 0.5T~ 10T, and 3T and 5T are commonly used. Mainly used for high-speed riveting of small thin materials, such as riveting and leveling of terminal connectors. Small die riveting is simple, manual continuous punching can be carried out, and the speed is 200~300/ min. Its characteristics are as follows. Punched parts are easy to damage! The maintenance rate will be higher! But maintenance is also very simple!

Three: After that, the things on the table should be put under a big table. It is a typical traditional punching machine, that is, an oblique punching machine, that is, a pedal punching machine. It is cheap and suitable for production in Dan Chong. It is more appropriate to do some simple stamping, such as tableware stamping, rough machining of cars, and relatively simple and low-precision production and processing! There are two kinds of hydraulic and pneumatic, and now there are more pneumatic ones!

Four: in addition to the inclined type, it belongs to the fixed desktop punching, which is also evolved from the inclined type, commonly known as opening punching! However, our domestic punching machines evolved from Japanese punching machines. At present, many domestic punching machines belong to fixed meters, and there are also national standards and non-national standards. The most important thing is not the appearance, but the processing technology and the cost and accuracy of parts. The earliest national standards are: Xu Forging, Yang Forging! Japan belongs to AIDA Komatsu! Taiwan Province Province: Xie Yi and Goldwind Taiwan Province Province also copied Komatsu and AIDA! But now there are more than 100 brands in China, and the difference in quality and price is big or small. The most important thing is the details and service!

Five: After all, the precision of the fixed table is not very good, and it is still difficult to make some high forging products. At this time, a kind of equipment higher than fixed open punch appeared, that is, closed punch, which is often used in large tonnage punch. Originally developed by Ada, it generally has two shafts, ranging from 1 10t to 3000t. It is often used in automobile large parts industry and computer mobile phone shell production industry!

Six. With the development of society and the rapid development of economy, the single production has been very backward, and the speed has been gradually improved, and the high-speed precision punch has been gradually born. But the speed required by different industries is different. For example, if the motor core is manufactured, it is difficult to achieve high-speed production because its impulse requirements are not in harmony with the die weight. Therefore, there are some medium-speed punching machines in the society, and the general speed is between 200-400/ min. However, there are also some punching machines that specialize in producing silicon steel sheets and silicon steel sheets!

Seven: the speed of the medium-speed punching machine is not slow, but it can't meet the requirements of more accurate punching. It's not that the speed is not good, but that the product needs speed to keep the product size requirements. If the speed is slow, the product will be deformed and there will be size problems. At this time, higher speed punching is needed. The common speed is 200~ 1000/ min, and the social speed reaches 1200, which is actually risky. Although the speed is only increased by 1~200, the impact is also great. The mentioned 1000 and 1200/ min are only limit values, and generally do not need to be reached. They are overloaded and do great damage to the punch press. Our punching machine is produced for this industry, with a general speed of 200~900/ min. The more famous brands still belong to Japan; Aida "Islamic State" and other brands!

Eight: The speed above medium and high speed is rare in China, but some enterprises will still use it. It is designed for high-precision products, and the products have certain requirements for punching machines. The general speed is between 1200~2500/ min, and the domestic technology is not mature enough to take risks. The best owners of this line are Swiss punching machines and Japanese AIDA DOBBY technology!

Nine: it belongs to a special model, controlled by a private server, and the punching machine punches holes irregularly, such as rising fast, slowing down or stopping at the bottom dead center, to ensure that the product materials do not rebound or deform. Mainly used in automobile aviation industry and high precision motor industry!

There are also some industry-specific punches and hydraulic presses, which have little contact and don't know much! The above are only the models and equipment I have contacted, and they are not complete. Experts in this field please give us more valuable advice, so that we can learn more about the maker who serves the society and changes our quality of life-punching machine!
