Specifications of carriage bolts
It mainly includes the outer diameter and material of the bolt. Common carriage bolt outer diameters range from 5mm to 20mm, and the material can be carbon steel or stainless steel. According to different uses, the standards of carriage bolts are also different, such as GB/T14 and DIN603, etc. In addition, the price of carriage bolts varies according to different materials and specifications. For example, the price of carriage bolts of 304 stainless steel is usually lower, while the price of carbon steel is higher.
Key features of our carriage bolts
1. High strength: Carriage bolts are usually made of high-strength materials, such as alloy steel or carbon steel, which allows them to withstand high loads and heavy-duty conditions. Therefore, they are ideal for connecting heavy equipment, machines and structures such as bridges, buildings and automobiles.
2. Easy to install: Carriage bolts are relatively simple to install as they usually only need to be inserted into pre-made holes and then secured with nuts or other fasteners. This simple installation saves time and labor and increases productivity.
3. Adjustability: Due to the U-shaped design of carriage bolts, they can be adjusted within a certain range to adapt to different connection needs. This makes them very flexible and can be used in a variety of different types of connectivity scenarios.
4. Good anti-vibration performance: The head and tail design of the carriage bolt can effectively prevent loosening and vibration, thereby ensuring the stability and reliability of the connection. This is important for equipment that needs to operate for a long time or is subject to vibration and shock. Carriage bolts offer the advantages of high strength, ease of installation, adjustability, and good vibration resistance, which make them widely used in many industrial and mechanical applications
Production process of carriage bolts
1. Material preparation
The material of carriage screws is usually carbon steel or alloy steel, and the selected material should have good mechanical properties and corrosion resistance. First, the selected raw materials need to be cut into blanks of appropriate length and diameter.
2. Screw head processing
In the screw head processing stage, one end of the blank needs to be processed into a standard screw head shape. There are many ways to process screw heads, including cold cutting, hot precision grinding, etc. The technical requirements are very strict. After the screw head is processed, heat treatment is required to make the screw head easier to process in subsequent processes.
3. Thread processing
Thread processing is a relatively important link. The specific steps are: first, machine a shallow groove at the screw head, clamp the part on the lathe, and rotate the entire part through the rotation of the lathe. At the same time, in accordance with strict requirements, the appropriate thread depth and size are set on the thread processing tool to perform thread processing.
4. Heat treatment
The heat treatment of carriage screws is relatively important. Its purpose is to make the internal structure of the screw material uniform, thereby improving the strength and hardness of the screw. The specific methods of heat treatment include normalizing, quenching, tempering and other methods.
5. Surface treatment
The surface treatment of screws usually uses galvanizing, chromium plating, etc. to protect the surface of the screws from damage such as corrosion and oxidation. After the surface treatment is completed, check the quality of the screws. This part of the work is very important and directly affects the service life and effect of the screws.
