A metal straightener is a virtual machine of metal stamping processing that requires high flatness of the material. The metal straightener machine transforms the surface tension of the material to shape and deform the material to achieve the desired flatness.
At present, the metal straightener machine we produce can only flatten the curvature of the longitudinal plane of the strip. Compared with the deformation of the cross-section of the material, the leveling effect is reduced, and the leveling effect we want cannot be achieved unless the stamping product is subjected to secondary leveling treatment.
When it comes to the correction ability of the leveling machine for the metal stamping, it is necessary to confirm the following issues:
- When the material width is the maximum designed width of the straightener, what is the actual material thickness?
- When the thickness of the material reaches the maximum capacity of the straightener, what is the width of the material used?
- What is the yield strength of the material?
- If the straightener is used in the blanking production line, we also need to know the speed requirements of the leveling.
According to the different straightening capabilities, the metal straightener is divided into the following categories:
Leveling roller diameter: 53mm-63mm
The number of leveling rollers: 7 pcs, 3 on top, and 4 on the bottom.
Material thickness range: 0.4-2.2mm, 0.3-3.2mm
Leveling roller diameter: 95mm-120m
The number of leveling rollers: 9 pcs, 4 on top, and 5 on the bottom.
Material thickness range: 0.5-4.5mm, 1.5-6.0mm
Leveling roller diameter: 40mm-58m
The number of leveling rollers: 15 pcs, 7 on top and 8 on the bottom.
Material thickness range: 0.2-3.0mm
Leveling accuracy: 300mm*300mm, ≤0.1mm
Leveling roller diameter: 20mm
The number of leveling rollers: 19 pcs, 9 on the top, and 10 on the bottom.
Material thickness range: 0.1-0.6mm
