The car industry has more and more requests for high-strength bolts.

Chen Guangzu, a member of Huaxia Automobile Industry Consultation Committee and a senior expert in Huaxia Automobile Industry, expressed his views on the current situation and future of our national automobile bolt company. Huaxia's company's research and production of high-strength bolts does not have the same difficulty. Chen Guangzu told reporters that in recent years, the automobile industry has requested more and more high-strength bolts, and the difficulty of the manufacturing process has also increased, but this does not mean that the country's internal fastener companies are unable to manufacture high-strength bolts., But it is whether the company has taken this seriously.

What material is rivet? What kind of rivet and what is its function?

A rivet is a nail-shaped object used to connect two parts (or components) with a through hole and a cap at one end. It is a kind of fastening hardware accessories, maybe many people don't know much about it. What is the material of the rivet? What is the type and function of the rivet? Don't worry, the following nine is hardware net will explain it for everyone, let's have a look.

Bolt, screw production process and the development direction of automotive bolts

Bolts and screws are the most basic mechanical components, which are widely used in various industries such as automobiles, industrial machinery and construction. Unlike welding and riveting, the biggest feature of bolts is that they can be simply removed even after fastening and can be reused by re-fastening.

Failure Analysis of Multiple Cracking in Automobile Bolt Assembly

Threaded connection is the most basic and highest standard mechanical part in automobile manufacturing technology. It is also the most widely used connection process in the automobile industry. It has simple structure and reliable connection. It has high precision, convenient assembly, and parts disassembly in the vehicle assembly process. Convenient, good reusability and other advantages. The parts are connected by bolts, which is to rely on the torque applied by "tightening" to achieve a close fit of the two connected bodies and have sufficient axial preload (I. e. axial tensile stress) to ensure reliable connection and normal operation of the connected parts. During assembly, the clamping force must be large enough to ensure that the connected parts do not move relative to each other during the working process; in addition, the applied clamping force must ensure that the bolt and the connected parts will not be damaged or plastically deformed during assembly and service.

The 3 most special bolts on the car, the last one knows very little!

The characteristic of the license plate bolt is that it allows you to screw it up, but it cannot be removed. That is, the legendary anti-theft bolts are now commonly used in the market with bolts. Last time I went to the DMV with my friends to get a license plate. After the DMV gave the license plate, I also gave a pack of bolts. When I opened it, I saw this kind of anti-theft bolt, which is much more advanced than the original one. Once the car was rear-ended, the bumper was knocked off, and an electric drill was used. It took a long time to remove these bolts.
