Introduction
Cold rolling machine is a technological process equipment used to roll various metal products. This machine is widely used in various types of metal cold rolling processes. It is mainly composed of unwinding device, roll forming unit, cutting unit, leveling unit and other auxiliary equipments. The main purpose of the cold rolling machine is to carry out cold rolling of metals such as stainless steel, alloy steel, aluminum and other types of metals to achieve various shapes and sizes desired by customers.
Principle of Cold Rolling Machine
The working principle of cold rolling machine is based on the floating rolling closure principle. As a metal rolling process, this principle involves the whole floating closure process of flat metal materials. It is well known that rolling gap is the most important factor in the cold rolling process. The material is passed through the floating rolling gap and then rolled repeatedly to the tail of the metal material. In each round of rolling, the rolling gap together with the metal material can move forward, so that the shape of metal material can be controlled by the corresponding rolling force and rolling process parameters.
Types of Cold Rolling Machines
Cold rolling machines can be divided into two basic types, namely two roll and four roll models. The two roll type is the simpler type and is designed to process material that is very thick. The four roll type is designed to work on thinner material and is capable of achieving higher rolling pressures. The four roll type can also be used to make products that have complex shapes, as it is more suitable for forming thicker sections with tighter tolerances.
Application of Cold Rolling Machine
The cold rolling machine is mainly used for rolling metal material with different specifications and shapes, such as steel sheet with width of 600mm or less, coil sheet, profile sheet and so on. The rolled products could be used for production of various automotive components and auto parts, railway parts, electric power parts and others. It can effectively reduce the cost of production, and improve production efficiency, making the manufacturing of parts and components more cost-effective.
In addition, It is also used in the production of coins, hardware pieces and other special products, as well as electric cookers, heaters, kitchen utensils and other supplies related to daily life.
Advantages of Cold Rolling Machine
1. It can be used to roll material in various shapes and sizes.
2. The rolled products have high dimensional accuracy and high surface quality.
3. Low labor force is required for the process.
4. It can eliminate the burrs and ridges on the surface of rolled products.
5. It can produce precision rolled products with excellent repeatability.
6. It can result in higher production rates and lower labor costs.
7. It reduces the material wastage.
8. It improves the overall product quality.
9. It reduces the production cycle time and improves productivity.
10. It increases the overall product longevity.
Conclusion
The cold rolling machine is an important piece of equipment that is widely used in various industries. It is used to roll metals such as stainless steel, alloy steel, aluminum and other types of metals, to achieve various shapes and sizes desired by customers. It offers various advantages such as dimensional accuracy, high surface quality, reduced wastage, lower labor costs, improved product quality and increased overall product longevity.
