The inadvertently “long” 2020 is coming to an end. Recalling that this period will definitely leave a rich and colorful time in the long history. Although there is a sudden “big exam” for the epidemic, it is also accompanied by a “new life” of opportunity: we are now Step into the era of intelligent interaction and at the same time move towards a new starting point for the accelerated development of the digital economy.
Stepping motor is an electromagnetic actuator that can convert digital input pulses into rotation or linear incremental motion. Each input of a pulse motor shaft steps a step angle increment. The total rotation angle of the motor is proportional to the number of input pulses, and the corresponding speed depends on the input pulse frequency. Stepping motor…
The drill bit diameter recommended in this table is for tapping processing , which can easily understand the drill bit diameter . It is selected according to the standard drill bit on the market.
As we all know, China and the United States have the world’s top Internet companies, such as Facebook, Microsoft and Amazon in the United States, and Alibaba, Tencent and JD in China.
Wire stripper is one of the tools commonly used by internal line electrician, motor repair and instrument electrician. It is used by power supply workers to peel off the surface insulation layer of wire head. Wire stripper can separate the insulation from the wire and prevent electric shock.
The beauty of materials is divided into three categories: the beauty of the original state; the beauty of the re-creation; the beauty of the recombination. The material itself has no emotional color. Its original color gives people an emotional guide. The material itself is only functional.
The solution or improvement of the problem mainly lies in the experience in engineering design and observation and analysis in daily maintenance.
With the accelerated development of the industrial Internet, large and medium enterprise customers and industry customers have become the main driving force for the growth of the cloud computing market.
The classification of epoxy resin adhesives has not yet been unified. Generally, they are classified according to their strength, heat resistance grade and characteristics.
5G, edge computing, cloud computing, etc. represent the IT field, while industrial automation and machine equipment are the OT field. An important feature of the development of digital enterprises in the direction of “Industry 4.0” is the combination of IT and OT. In the past industrial 3.0/3.X era, OT and IT were separated, but now digital and intelligent enterprise IT and OT need to be integrated. This is the essence.
There are many reasons for the deformation of aluminum parts, which are related to the material, the shape of the parts, and the production conditions.
A set of reliable plastic mold design is mainly reflected in the quality of the molded plastic products (appearance quality and dimensional stability), convenient, rapid, and concise processing and manufacturing.
Most of the spring designs used in LCA are compression coil springs or extension coil springs. These two spring designs involve the following items.
If the lighting distribution box (board) is used in a humid and dusty place, it is easy to mold and leak; in addition, if the wooden box (board) is not treated with flame retardant, it is easy to cause fire and is a hidden danger of insecurity.
Many applications of lightweight conveyor belts require it to be tensioned first, and then to change its length by adjusting any rollers. In this case, the tension in the belt will change throughout the life of the belt.
What is IGES, STEP file – what is it used for? Introduction to IGES /STEP: IGES, STEP is a Cad file format that allows you to open a 3D model and edit it in any software. IGES and STEP are widely used neutral CAD formats that are accepted in all software. In IGES, the output is in the surface, while the STEP file retains the assembly hierarchy, and the output is a mixture of solids/volumes and surfaces (only solids are used in most cases).
What is a heat-shrinkable tube, a heat-shrinkable tube is a special material of plastic, which can shrink quickly at high temperatures. When we connect two wires. Put the heat shrink tube on the metal connection. Then use a heat gun to bake the heat shrink tube. It will shrink quickly and wrap around the metal joints, so that we don’t need to use tape to wrap it. Improve work efficiency, and the safety and reliability of the connection.
Recently, the China Association for Science and Technology released 10 scientific problems that have a guiding role in scientific development and 10 engineering problems that have a key role in technology and industry. What are these 20 questions? Let’s refer to it together!
The hydraulic system uses Pascal’s law in hydrostatics, uses oil or other liquids to transfer the pressure in the liquid, so as to realize the small pressure to control the large pressure, which is similar to the lever principle.
The solder bar will appear in the soldering process. The main reason for this phenomenon is the poor reducibility or insufficient amount of the flux. Below, I will analyze it for you.
Employees are the precious wealth of an enterprise. An excellent company is bound to treat itsemployees as jewels in the palm .
As a manager, if you always want to solve problems in private, you will be incurring dereliction of duty that cannot fulfill your mission. An important principle of public management is that managers do not do obscure work, but are sound, colored, and powerful. Only by coming out can management be effectively improved and decision-making can be implemented in place.
With the continuous improvement of sensing technology, intelligent technology and computing technology, intelligent mobile robots must be able to play the role of human in production and life. So what are the mobile robot positioning technologies mainly involved? After summarizing, mobile robots currently mainly have these 5 positioning technologies.
American scientist Angela M. Belcher has developed such a new technology that can “captive” viruses in lithium batteries, let them work for us, and continue to produce power.
