Automobile structural parts refer to the load-bearing parts or stress-bearing parts in the automobile, which are closely related to automobile safety. In the automobile body, many structural parts are installed on the nodes of the body structure and connected with other structural parts to form a high-strength frame with deformation resistance. Because of the complex structure and high precision requirements of such parts, multi station progressive die is usually used for production. Although the progressive die for automobile structural parts has many advantages, such as high production efficiency, saving material cost and good product accuracy, the combination of the structural…

There are certain technical difficulties in machining trapezoidal thread on CNC lathe, especially in high-speed cutting. It is not easy to observe and control during processing, and the safety and reliability are also poor. This requires correct tool geometry and processing technology, and introduces an efficient and feasible processing method. Whether it is on an ordinary lathe or a numerical control lathe, it is always difficult for secondary and higher vocational students to process trapezoidal threads. In particular, the high-speed turning of trapezoidal threads on a numerical control lathe has not been introduced in most books and textbooks. It is…

The processing process rules of vertical CNC machining center are reflected in three aspects: preparation before startup, startup processing, contents and scope of self inspection by workers. In addition, the article summarizes the causes of errors, special attention and corrective measures for reference······ 1、 Preparation before startup: 1. After the machine tool is started or reset according to the emergency stop, first return to the reference zero position of the machine tool (i.e. return to zero), so that the machine tool has a reference position for its subsequent operation. 2. Clamping workpiece: 3. Before clamping the workpiece, clean all surfaces…

The machine tool networking project is to build a workshop level distributed control network at the equipment level (CNC machine tool), collect machine tool data and other production data in real time, realize the effective management of CNC programs and related production factors (part drawings, processing technology, tool holder and measuring tool list, etc.), and realize the visual display of machine tool status, etc., which will lay a good foundation for the effective establishment of the next MES platform, Therefore, it is implemented first. Overview of machine tool networking project The implementation of the machine tool networking project provides technical…

When the pressure exceeds the atmospheric pressure on the earth by one million times or even one billion times, the atomic behavior will be very different. Understanding the reactions of atoms under such high pressure conditions can lead to the production of new materials and enable scientists to provide valuable insights into the composition of stars and planets and the universe itself. These are one of the reasons why the University of Rochester has shifted its attention to the relatively new field of high-energy density physics. Another reason is that the university is ready to make a significant contribution to…

Engineers from the Viterbi School of engineering at the University of Southern California (USC) are using lobster inspired 3D printed armor to prevent sports injuries. This lobster like printed armor may be very effective in preventing chronic traumatic encephalopathy. Both lobster and skinned shrimp have shells based on chitosan. The structural fibers of these shells are spirally aligned, and these spirals are constantly rotating. This fiber alignment makes it difficult for small cracks to expand into larger cracks, making it difficult for lobsters to decompose. Inspired by this, researchers found that lobster shell is an excellent model for protective body…

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.
