What's working principle of sheet metal flattening machine?

Sheet metal flattening machine is a kind of equipment used to level metal products or materials, which is widely used in metal processing industry. It can process various metal materials in different forms, such as metal sheets, metal meshes, metal rods, metal parts, etc. The function of sheet metal flattener is not limited to leveling the surface of materials, but also to eliminate the stress inside the materials to a certain extent, thereby improving the quality and stability of products.

In this article, KINGREAL CEILING MACHINERY will discuss in detail the working principle, main parameters, advantages and application fields of sheet metal flattener.

The core principle of steel plate flattening machine is to use the upper and lower rollers to achieve the leveling of metal materials through multiple positive and reverse bending. The structural design of KINGREAL CEILING MACHINERY sheet metal flattener is very delicate, and its working process can be divided into the following key steps:

1.1 Arrangement of leveling rollers

The design of sheet metal flattening machine is usually arranged from the inlet to the outlet, and each group of leveling rollers is arranged in an upper and lower staggered manner. These rollers are divided into upper and lower rows, and at least one of them works in the form of downward pressure. This arrangement ensures that the material is subjected to uniform pressure when passing through the leveler.

1.2 Material entry and leveling process

When the metal material to be leveled enters the steel plate flattening machine from the feed port, it will first pass through the staggered action of the upper and lower leveling rollers. When these rollers rotate, they continuously apply pressure to the material to cause it to bend. This bending is performed alternately in the forward and reverse directions, with the purpose of gradually reducing the original curvature and unevenness of the material through multiple bending.

1.3 Elimination of internal stress

Through repeated bending, the sheet metal flattener can effectively reduce the stress inside the material. This process not only makes the surface of the material flat, but also fundamentally eliminates the internal stress caused by processing, welding and other processes. This is of great significance for improving the stability of the material and the accuracy of subsequent processing.

The working principle of the steel plate flattening machine directly affects its performance and effect. The following are three important parameters:

2.1 Diameter of the leveling roller

The diameter of the leveling roller is a key factor affecting the leveling effect. Generally speaking, the smaller the roller diameter, the better the leveling effect. A small diameter roller can provide a larger contact area, so that the material is subjected to more uniform pressure when passing through, thereby achieving a better leveling effect.

2.2 Roller pitch of leveling rollers

The roller pitch refers to the distance between the upper and lower rollers. The setting of the roller pitch directly affects the bending degree and leveling quality of the material during the leveling process. Generally, the smaller the roller pitch, the better the leveling effect, because a small roller pitch can increase the number of bending times of the material, making the leveling more thorough.

2.3 Number of leveling rollers

The number of leveling rollers is also an important factor affecting the performance of the sheet metal flattener. An increase in the number of rollers means that the material will experience more positive and reverse bending during the leveling process, which will significantly improve the leveling quality. For example, if the sheet metal flattening machine is equipped with more rollers, the material will experience more bending when passing through, thereby achieving a more detailed leveling effect.

The design of the steel plate flattening machine is based on the elastic-plastic bending deformation mechanism of metal materials. Metal sheets of different thicknesses and materials have different deformation characteristics during the leveling process:

- Thin sheets: Thin sheets require relatively less leveling force during leveling, so smaller rollers and smaller roller spacing can be used. In this case, the multi-roller design of the sheet metal flattener can provide enough bending times to ensure the leveling effect.

- Thick sheets: For thicker metal sheets, due to the larger leveling force, a larger diameter leveling roller is required. Larger rollers can withstand higher pressures and effectively reduce deformation and damage to the material during the leveling process.

Steel plate flattening machines are designed and classified based on the thickness and characteristics of the applicable materials. This design principle ensures that the sheet metal flattening machine can handle a variety of different types of metal materials.

4.1 Improve the flatness of the product

Steel plate flattening machines can effectively improve the flatness of metal materials and ensure the smooth progress of subsequent processing. The leveled material shows higher stability and consistency during use, thereby improving the quality of the final product.

4.2 Fast leveling speed

Sheet metal flatteners are highly efficient and usually only take a few seconds to level a metal material. This efficient working ability makes sheet metal flattening machines an indispensable equipment in modern production lines.

4.3 Easy to clean and maintain

The sheet metal flattener of KINGREAL CEILING MACHINERY is designed with the convenience of cleaning and maintenance in mind. The rollers of the steel plate flattening machine are removable, which is easy to clean and maintain, keeping the equipment clean and operating normally, and extending its service life.

4.4 Eliminate internal stress

Sheet metal flattening machines can not only level the surface of metal materials, but also effectively eliminate internal stress. This function is crucial to improving the processing performance and stability of materials, especially in the application of high-precision processing and high-strength materials.

Sheet metal flatteners are widely used in the metal processing industry, mainly involving the following fields:

5.1 Aerospace

In the aerospace industry, the flatness and precision of metal materials are extremely high. sheet Metal flattening machines can provide high-quality leveling effects to ensure the reliability and stability of materials in complex processing.

5.2 Automobile Manufacturing

During automobile manufacturing, the quality of metal parts directly affects the performance and safety of the whole vehicle. The sheet metal flattener can be used to process the metal materials of automobile parts to improve their flatness and strength, thereby improving the overall performance of the car.

5.3 Machinery Manufacturing

The machinery manufacturing industry has equally strict requirements on metal materials. The sheet metal flattening machine can improve the processing accuracy of metal materials and ensure the good fit and stable operation of mechanical parts.

5.4 Construction Industry

The application of the steel plate flattening machine in the construction industry is mainly reflected in the processing of metal structural parts. Through leveling, metal structural parts can better meet the design requirements and improve the quality and safety of the building.

5.5 Electronic Industry

In the electronics industry, the sheet metal flattening machine is used to process various metal casings and parts to ensure that their surfaces are flat to meet high standards of appearance and functional requirements.
