For those who do not understand the purchase of high-strength bolts, or the sales staff, the company does not specialize in producing high-strength bolts. Therefore, they do not know much about what kind of screw material is used for high-strength bolts. It is not clear what high-strength bolt materials are all? The person who might sell the screw only knows that the high-strength bolts are stainless steel and iron, that is, carbon steel. But what are the details of the materials, they are not...
Development of stainless steel round steel, 304 stainless steel round steel stainless steel The tissues born in 1910-1914 were martensitic, ferrite and austenitic stainless steels. From the chemical composition, they are mainly Fe-Cr and Fe-Cr-Ni. In the nearly three decades from the end of the First World War to the end of the Second World War, the development of stainless steel round steel, 304 stainless steel round steel stainless steel (ie 1919 to 1945). With the development of various...

Explosive bolts, when the layman heard it, thought it was like a bomb, the bolt that would explode! And the industry will smile a little: please listen to me. The debris-free explosion bolts, referred to as explosion bolts, are mostly used for multi-point connection separation surfaces. Each blast bolt is shaped like a normal bolt with internal explosives and igniters. When separated, the explosive is detonated, the shear lock is sheared or the groove is broken along the bolt, and the two...
We all know the important bolt joints, the bolts need to be tightened, and this tightening is a quantitative evaluation index, that is, tightening torque (or corner, etc.), different bolts are used in different applications, the tightening torque is not the same, even Bolts of the same specification, different manufacturers, precision, and lubricated coatings, the bolt tightening torque that needs to be applied is also different, because in the design of the bolt, we want the pre-tightening...
If we need to use the nut on the thin iron piece, because the iron piece is too thin to be tapped and welded, it is necessary to use a rivet nut or a rivet nut. Rivet nuts and rivet nuts are widely used in the sheet metal industry. The installation of the rivet nut and the rivet nut requires the use of professional tools. What should we do if we need to use a rivet nut in our home life? Buy a rivet nut gun, not only a little expensive, but also not commonly used. We can do this using the...
Bolts made of high-strength steel, or which require a large preload, can be called high-strength bolts. High-strength bolts are often used for the connection of bridges, rails, high-pressure and high-pressure equipment. Brittle fracture. High-strength bolts applied to high-pressure equipment. In order to ensure the sealing of the container, a large prestress is required. The coupling of the high-strength bolts needs to be tightened during assembly so that the tightened threaded assembly...

I believe that everyone is no stranger to bolts. It is possible to use bolts in various lamps, furniture, etc. in the home. There are many sizes of bolts, big and small. What is the bolt specification? What is the expansion bolt specification table? Let's take a look at it next. What is a bolt ? Bolt: A type of fastener consisting of a head and a screw (a cylinder with an external thread) that is to be fitted with a nut for fastening two parts with through holes. This type of connection is...
What is the difference between stainless steel bolts and iron bolts? Stainless steel screws and iron screws, can not say which is better, mainly depends on the use of occasions. In terms of corrosion resistance, stainless steel screws are obviously better than iron screws. Because of the anti-corrosion of stainless steel, it relies on the inside of the chromium to react with the oxygen in the air to form a chromium oxide protective layer to protect the stainless steel screws from corrosion. If...
When the hexagonal bolts are loaded into the carton and need to be stacked in the warehouse, the stacking height is not allowed to exceed 2.2m. Under the premise of not exceeding the total height of the stacking code, the carton angle is required to be stacked diagonally up and down. Code storage, avoiding interlaced code placement, prohibiting large box press small box or small box pressing large box size. Secondly, the storage location should be at a certain distance from the ground, wall,...
At present, the bolt fastening used in almost all industries requires control strength, that is, the so-called torque control torque refers to industrial fastening with a predetermined torque or a predetermined torque and angle to ensure sufficient clamping force. Ensure the reliability of the threaded connection. Bolt fastening is a very complicated physical process. The most important factors affecting bolt fastening are torque, preload, friction, and material hardness. As long as the above...

Introduction of Vectors To facilitate the discussion of interference checking, first make a vector at the key points of the part, then make a tool center path and mark the direction. The path of the center of the tool can be compared with the direction of the program path to determine whether or not to interfere with the difference between the two. Here, only the interference problem of the shape processing of the straight line-straight line, straight line-arc shape is discussed. Among them,...
