With the acceleration of the development of general aviation in China, China's general aviation manufacturing industry has begun to catch up. From the manufacturing of auxiliary parts and components in the general aviation field, the development of general aviation monitoring and security inspection system, to the manufacturing of general aircraft, China's independent R & D capability in the general aviation field has been greatly improved with the transformation and upgrading of China's equipment manufacturing industry, the promotion of the development of the general aviation industry and the military civilian integration strategy. Tianhe defense company is a representative of developing the…

In today's Internet society, words such as "big data", "cloud computing", "cloud platform" and "Internet +" have once become hot words in the mouth of the majority of netizens. However, few people understand the true meaning of these words. At the turning point of manufacturing transformation, what will big data do? Let's talk about big data today. What is big data? Massive data set refers to the data set that cannot be captured, managed and processed by conventional software tools within a certain time range. It is a massive, high growth rate and diversified information asset that needs a new…

How to replace anti-theft nuts of automobile tires? Many car owners may not know much about the anti-theft nuts of automobile tires. In fact, it is a fastening screw that is different from other screws and cannot be removed with a conventional socket wrench. In high-end luxury models, anti-theft screws are very common. Don't underestimate such a screw. It plays a very important role in automobile anti-theft. So where are these screws? How should I replace it? Here, the quick screen editor will briefly introduce how to replace the anti-theft nuts of automobile tires. The principle of automobile tire anti-theft…

The robot tool changer makes the application of robots more flexible by automatically changing different end effectors or peripheral devices. These end effectors and peripherals include, for example, spot welding guns, grippers, vacuum tools, pneumatic and electric motors, etc. The tool quick change device includes a robot side for mounting on the robot arm and a tool side for mounting on the end effector. The tool quick change device can connect different media such as gas, electric signal, liquid, video, ultrasound, etc. from the robot arm to the end effector. The advantages of the robot tool quick change device are:…

As a tool directly or indirectly installed on the machine tool to complete the workpiece processing task, we must consider two applicability and one matching. That is, it is applicable to the selected machine tool, the selected workpiece, the processing task and the matching with the machine tool. However, this paper mainly discusses how to grasp the matching between the tool and the machine tool from the matching of the tool. When it comes to the matching of tools and machine tools, you may first think of the matching of shapes and dimensions. Indeed, the matching of the shape and…

Cause of stainless steel wrinkling: when the metal flows inward through the tensile ring in a radial manner, the compression force may cause wrinkling, and the clamp will prevent the occurrence of such wrinkling. If the metal flows unevenly or without the support of the stretching ring, wrinkles will begin to occur. Thin materials require more fixing force than thick materials. How to control the fixing force in stainless steel stamping process? The fixing force of stamping parts can be controlled by many methods. First, use the fixing pad with relatively flat surface. When the metal flows under the fixing…

Our common crushers and pulverizers belong to crushing machines, which are machines that use mechanical force to crush solid materials and turn them into small pieces, fine powder or powder. Powder flour, crushed ore, ground pigment, dye, cement raw materials, clinker, etc. all need to use grinding machinery. So what grinding machinery should be selected for different purposes? Here, the quick screen editor will briefly introduce how the crushing machinery is classified. Air mill Steam, air or other gases are injected into the engine body at a certain pressure to generate high-speed rotating vortex. The material particles in the machine…

At present, there are two kinds of analytical instruments in the market: laboratory analyzer and process analyzer. Now, I will briefly introduce the instruments suitable for gas composition analysis. one Common laboratory analytical instruments 1. Austria gas analyzer As a classical chemical manual analyzer, Austria's gas analyzer has the advantages of low price, convenient operation and easy maintenance. This instrument has been widely used for the determination of CO2, O2, CO and H2 in gas. The principle is to use absorption method to determine acid gas, unsaturated hydrocarbon, oxygen and carbon monoxide, make hydrogen burn on copper oxide, and make…

Conventional forging Forging is one of the early forming processes for aluminum wheel hubs. Forged aluminum wheel hub has the advantages of high strength, good corrosion resistance, accurate size and small processing volume. Generally, its weight is only equivalent to 1 / 2 or less of the steel wheel of the same size. The grain flow direction of forged aluminum hub is consistent with the stress direction, and its strength, toughness and fatigue strength are significantly better than that of cast aluminum hub. At the same time, the performance has good reproducibility, and almost every hub has the same mechanical…

To be honest, the first time I heard the word "packing" in this small edition, I didn't know what it was. After online inquiry and relevant information search, I learned that packing is also known as "braided packing". It is a kind of sealing packing made of expanded graphite wire. Next, this small edition will introduce in detail what is packing and how it works? If you want to know, please join us to learn! Prepare packing Packing, also known as sealing packing, is usually woven from softer linear materials. Usually, strips with square or rectangular cross-sectional area and circular…
