Automation based on monitoring computer (PC), programmable controller (PLC), human machine interface (HMI), intelligent instrument, industrial control communication network DCS (distributed control system) and FCS (field bus control system) has become the technical pillar of modern factories and has been widely used in modern production lines at home and abroad. According to the statistics of relevant departments, among the PLCs shipped worldwide in recent years, according to the end users, automobiles account for 23%; Food processing accounted for 16.4%; Chemical industry accounted for 14.6%; Metal mines accounted for 11.5%; Papermaking accounts for 23.1%. It can be seen that the application…

Hydraulic plate shearing machine is a kind of plate shearing machine driven by hydraulic pressure. With the help of the moving upper blade and the fixed lower blade, a reasonable blade gap is adopted to apply shear force to the metal plates of various thicknesses, so that the plates are broken and separated according to the required size. What this article will introduce to you today is the working principle and operating procedures of the hydraulic plate shears? If you want to know about children's shoes, please follow me to have a look! The main performance characteristics of the hydraulic…

Intelligent hardware, HTTP protocol and JSON data format, especially restful API, are undoubtedly dominant. Various cloud services and data transmission are based on these protocols. JavaScript provides the best support for HTTP and JSON. When the system is developed with JavaScript, it naturally connects the cloud services and cloud resources on the Internet. Intelligent hardware, including cloud storage, cloud computing and a series of resources, can be easily called, just like you access various cloud services on your mobile phone. The rise of microservice architecture on the server side allows each node written in JavaScript to serve as a microservice…

1. The connection between the servo motor shaft and the lead screw is loose, causing the lead screw and the motor to be out of synchronization, resulting in dimensional error. During detection, it is only necessary to make marks on the coupling between the servo motor and the lead screw, and move the workbench (or tool rest) back and forth with a fast rate. Due to the inertia of the workbench (or turret), the two ends of the coupling will move relatively. This kind of fault usually shows that the machining size changes only in one direction, and it can…

Introduction: Spiral wound gasket mainly includes metal wound gasket, graphite wound gasket, graphite metal wound gasket, metal graphite wound gasket, inner and outer ring wound gasket, metal asbestos wound gasket, metal tetrafluorocarbon wound gasket, etc. The spiral wound gasket is made of "V" shape (or "W" shape) metal belt and non-metal belt overlapping each other and continuously wound. The metal belt is fixed by spot welding at the beginning and end. Performance characteristics: 1. It is applicable to a wide range of working conditions. It can withstand high temperature, high pressure and adapt to the service conditions under ultra-low temperature…

Recently, Fitbit has indeed experienced a difficult time, and I think that if Fitbit wants to really understand the future of wearable devices and biometrics, this is a necessary process. This theory is not only applicable to Fitbit, but also to the whole wearable device industry. This is a game about waiting and development. You see, some people may have seen that the wearable device market seems to be saturated at present. Some companies have decided to launch, while others have just begun to step in. With the miniaturization of hardware, wearable devices and facilities are becoming more fashionable and…

Cost reduction is the eternal theme of enterprise management, but this issue is now very important and urgent, especially for China's manufacturing industry in the era of low profit. The more nervous, the less blind. What can't enterprises do in the process of reducing costs? According to relevant reports, if the manufacturing cost in the United States is set to 1, the manufacturing cost in China will reach 0.96, which is quite close to that in the United States. The manufacturing cost in some industries, such as the light textile industry, is even higher than that in the United States.…

The industrial door is a common facility for enterprises. It is suitable for large warehouses, logistics industry, medicine, food, factories and mines and other industries with high requirements for opening speed, thermal insulation, sound insulation, sealing and wind resistance. Especially where the door opening is large and it is inconvenient to install the ground door body. The operation of the industrial door mainly depends on the motor to drive the door body, so if the motor fails, the industrial door cannot operate. The following is a list of the reasons why some industrial door motors cannot rotate and their solutions:…

There are three common polishing methods: mechanical polishing, chemical polishing and electrochemical polishing, which have their own advantages and disadvantages. As for the specific choice, it is also necessary to comprehensively consider and select the appropriate polishing method according to the structure and size of stainless steel products and product performance requirements. 1. Mechanical stainless steel polishing. It has the advantages of good levelness and high brightness after processing. Its disadvantages are high labor intensity, serious pollution, and complex parts can not be processed, and its gloss is not consistent, the gloss retention time is not long, and it is…

1、 Selection of positioning datum In the process specification design, the correct selection of positioning datum has a vital impact on ensuring the processing requirements of parts and arranging the processing sequence reasonably. The positioning datum can be divided into fine datum and rough datum. The rough surface on the blank is used as the positioning datum. This positioning datum is called rough datum. The machined surface is used as a positioning reference, and this positioning reference becomes a fine reference. When selecting the positioning datum, the precise datum is often selected first according to the machining requirements of the…
