The combination of laser and welding is a great breakthrough in traditional industry. It not only improves the welding quality, but also shortens the welding cycle. Today, laser welding processing technology has been applied in many industries, the most common being high-tech electronics, automobile manufacturing and precision processing. However, in the field of automobile manufacturing, the application proportion of laser welding is still in the lower middle level. The concept of laser welding is also credited to Volkswagen. In the dazzling automobile market, Volkswagen brand has always been favored for its durability. This is exactly what the traditional welding processing…

All control of the 6-axis industrial robot is completed by a microcomputer. The other is decentralized (level) control, that is, multiple microcomputers are used to share the control of the robot. For example, when the upper and lower level microcomputers are used to jointly complete the control of the robot, the host computer is often used to be responsible for the management, communication, kinematics and dynamics calculation of the system, and send command information to the lower level microcomputers; As a subordinate slave, each joint corresponds to a CPU to perform interpolation operation and servo control processing, realize a given…

As one of the most widely used digital products in modern society, smart phones have become the most essential items in people's daily life. However, the development history of mobile phones is only 44 years, and the popularity of smart phones is only in the last decade. The changes in the shell materials of mobile phones are very significant. From the beginning of plastic to the new generation of materials represented by metal glass today, what is the best material for mobile phones? First, let's sort out the common cell phone shell materials, such as plastic, metal, glass, ceramics, wood,…

As we all know, rare earth has always been China's national defense strategic armament material. At the same time, due to its irreplaceable role in national defense and military weapons and equipment, and its reserves are extremely low, all countries are making long-term reserves. At present, the advanced weapons and equipment of western countries are extremely dependent on China's rare earth materials. The United States, in particular, relies almost entirely on imports from China. Of course, in addition to the military field, these materials are also used in smart phones, global positioning systems, automotive electronic components, computers, computer screens and…

Tool steel is particularly attractive to manufacturers compared to steel. As its name suggests, tool steel is very suitable for making tools. It is a very hard, highly heat-resistant and wear-resistant material, with multiple grades, suitable for various applications. For such a high-quality material, the 3D printing industry certainly has a great demand, as CEO markforge pointed out in a recent interview. Markforge will develop tool steel materials for its metal x 3D printer. It is exciting that nanosteel has taken the lead. Today, the company announced the launch of a new 3D printing tool steel material, which is also…

Lithium batteries are widely used in mobile devices such as mobile phones and laptops. Dangerous events such as ignition of mobile devices due to battery short circuit are also increasing. Scientists from China and the United States have jointly completed a new study. They have added nano-sized diamond particles to the electrolyte of lithium batteries to prevent the formation of deposits inside the batteries that lead to short circuits and avoid fire accidents caused by battery short circuits. Lithium battery has high energy density and good discharge performance, and is widely used in industry and consumer electronics. However, if pure…

Mechanical drawings are the summary of technical requirements and the necessary data for robots. Remember to collect them! ▌ general technical requirements 1. Remove scale from parts. 2. The processing surface of the parts shall be free from scratches, scratches and other defects that damage the surface of the parts. 3. Remove burrs and flash. ▌ heat treatment requirements 1. HRC50 ～ 55 after quenching and tempering. 2. Parts shall be subject to high-frequency quenching, tempering at 350-370 ℃, and hrc40-45. 3. Carburizing depth: 0.3mm. 4. Conduct high temperature aging treatment. ▌ tolerance requirements 1. The unspecified shape tolerance shall…

1、 What is non-standard mechanical design? In short, it is the design of non-standard equipment, non-standard parts and non-standard tooling. For example: C616, C620, C630, c6125, M7475, b650, M131 and other equipment are well-known standard equipment in the machining industry, so there are many special equipment not included in the standard equipment, which is the work goal of non-standard designers. Non standard machinery is a mechanical product that is not finalized. Generally, it can not be bought directly in the market. It should be customized from the manufacturer. The size and shape of machines with the same function may be…

The process of the birth of an innovative product from birth to birth should be like this: a little adorable idea, and then let a designer to discover the shape you give the product. Next, let the product upgrade in dimension -- from the two-dimensional of the drawing to the three-dimensional of the hand plate, then adjust the idea; Then, adjust the design; Then, adjust the material; Then, adjust the process. Finally, the goddess in my mind appeared, so, mold opening, production, marketing It can be seen that in the whole process, the link around the hand board is the…

"CNC" refers to the numerical control technology of computerized numerical control (numerical control for short). Traditional machining is operated by hand with ordinary machine tools. When machining, shake the mechanical tool by hand to cut metal, and measure the accuracy of products with caliper and other tools by eyes. Modern industry has long used computer digitally controlled machine tools for operation. CNC machine tools can automatically process any products and parts directly according to the program compiled by technicians in advance. It is a method of using digital information to control the movement and machining process of machine tools. The…
