Huizhou screw factory: what are the common sense of the application of screws?

Screws are tools that use the physical and mathematical principles of circumferential rotation and friction of the inclined surface of an object to gradually tighten each part of the object. So,Huizhou Screw Factory: What is the common sense of the application of screws?

Huizhou screw factory: what are the common sense of the application of screws?

1. First remove the silt on the surface of the broken wire, crush the center of the section with a central spear, and then use an electric drill to drill a hole in the center of the section with a drill bit with a diameter of 6-8mm to ensure that the hole is drilled through. After the drilling is completed, remove the small drill bit, replace it with a drill bit with a diameter of 16mm, and continue to expand the hole of the broken bolt.

2. Take a welding rod with a diameter of less than 3.2mm and weld the broken bolt from the inside to the outside with a small and medium current. At the beginning of welding, take half of the total length of the broken bolt. When welding starts, do not start for too long to avoid burning through the outer wall of the broken bolt. After welding to the upper end surface of the broken bolt, continue to weld a cylinder with a diameter of 14-16mm and a height of 8-10mm.

3. After surfacing, hit the end face with a hammer to make the broken bolt vibrate along its axial direction. The heat generated by the previous arc and the subsequent cooling coupled with the vibration at this time will loosen the thread between the broken bolt and the body.

4. Watch carefully. When a trace of rust is found to leak from the fracture after knocking, M18 nut sleeve can be taken from the surfacing column head to weld the two together.

5. After welding, when it becomes cold or hot, use a ring wrench to screw it around the nut. You can also use a small hammer to knock the end face of the nut while screwing, so that the broken bolt can be taken out.

6. After removing the broken bolt, use a suitable tap to process the thread in the frame again to remove the rust and other debris in the hole.

Huizhou screw factory: what is the scope of the use of screws?

There are many names for screws. Everyone may call them different. Some people call it screws, some call it screws, some call it standard parts, and some call it fasteners. Although there are so many names, they all mean one thing. It's all screws. Screw is a general term for fasteners. The principle of the screw is to use the physical and mathematical principles of the circumferential rotation and friction of the inclined surface of the object to gradually tighten the parts of the object.

2. Screws are indispensable in daily life and industrial production, so screws are also called industrial meters. The application range of screws is: electronic products, mechanical products, digital products, power equipment, mechanical and electrical products. Screws are also used in ships, vehicles, water conservancy projects, and even chemical experiments.

There are many kinds of screws, whether it is a small screw for glasses or a large screw for large-scale electric engineering. Screw accuracy is usually 6g (grade 2, American specification 'IFI' is 2A teeth), and thick screws for construction engineering are 1g.

4. Screws are widely used, so the screw market is large, resulting in more screw manufacturers. When choosing a professional screw manufacturer, buyers need to know some professional basic knowledge of screws, such as screw classification standards, American screw specification tables, etc.
