The development process of leveling process:? ————————— Content source: leveler/www.arku.cn
1, hammer and flame
Traditional leveling process. In this process, the workpiece is heated first, and then "leveled" with a hammer. This leveling process is very time-consuming and the operator needs to have rich experience.
2. Plate bending machine
Some sheet metal processing personnel use plate bending machine to eliminate large flatness defects. Although this emergency plan has brought remarkable improvement effect, the internal stress in the material has not been eliminated. For wide sheet metal parts, the operation is very difficult, and it usually takes more than 25 minutes to level a workpiece.
3, pressure straightener
Similar to using a plate rolling machine, it takes a lot of time. It is usually used for sheet metal parts with a thickness of more than 60 mm. It usually takes 20 minutes to level the workpiece with this process.
4. Roller straightener
Roller straightener can straighten the plate quickly and conveniently. This machine is often used to flatten laser cutting parts and flame cutting parts with a thickness of 0.5 to 60 mm For parts with low leveling quality requirements, the mechanical roller leveler can quickly solve the problem. However, if the requirements are high, it is often necessary to use a leveling machine to level the sheet metal parts for 5 to 6 times.
5. Servo hydraulic precision leveler
Servo hydraulic precision leveling machine is specially designed for demanding leveling operation. Such as: FlatMaster produced by ARKU company? . The leveling rollers are supported to the best extent and the distance between them is very small. The integrated leveling gap adjustment device ensures that the leveling gap remains constant throughout the leveling process, including when the cross section of the part changes. Even those burning and cutting parts that are difficult to level are not a problem. It only takes a few minutes to make it smooth, and there is almost no pressure.
6, roller leveling process
When roller leveling is used, a piece of plate will undergo many continuous alternating bends. ?
From the entrance to the exit of the roller straightener, each group of straightening rollers is staggered. ?
In this way, one of the two opposing leveling rollers is always the lower pressure roller. ?
From the first leveling roller to the outlet, the alternating bending degree gradually weakens. ?
The bending process is similar to a gradually weakening sine curve. ?
By elastic-plastic staggered bending and reducing deformation, the plate will become flat, and more importantly, the stress will be eliminated.
