Roll shear blade for aluminium coil slitting

Item No.: GMX220119658
Aluminium sheet is one of most widely used steel in our life. As our life gets better and better, the requirements to aluminium slitting is more strict than ever. In order to solve such questions, we design and develop more precision slitting knife.

  As a metal in the earth's crust second only to oxygen and silicon, aluminum has gradually become one of the most common metals in our lives due to its rich content and good performance, and aluminum plates made of aluminum have gradually penetrated into our lives. All aspects of China. Aluminum plate has some of the following advantages: 1. Low temperature resistance.2. Corrosion resistance. However, with the application of more and more aluminum products, people have a higher pursuit for the precision of aluminum products. How to slit and cut aluminum strip profiles with higher precision and no burrs has become the primary problem of major slitting manufacturers. Our company has been committed to panel slitting and cutting for more than 30 years. According to the high requirements of aluminum wire, the material G6, which is specially suitable for thin and thick plate slitting, has been researched. G8 can meet the high precision requirements of aluminum plate slitting.           
  Some grades and their performance:

  Grade Yield Strength Tensile Strength Common Thickness
1050 ≥75MPA 95-125MPA 0.22-0.26
2A16      ≥265MPA ≥410MPA  
3003  ≥115MPA 140-180MPA 0.05-2
4043   ≥274MPA 0.4-0.6
5005 ≥125MPA 155-195MPA  
6061  ≥110MPA  ≥205MPA 1-2
7075  ≥560MPA  ≥495MPA  
8011 110MPA 125-165MPA  
  Main application:
   Aluminum plates are mainly used in radiators, aluminum plates for tankers, air-cooled water coolers, water-cooled intercoolers, oil coolers, parallel flow evaporators, stacked generators, water-cooled plates, battery coolers, low-temperature radiators, water tanks, cooling plates , Honeycomb panels, honeycomb cores, transformer radiators, cabin air-conditioning condensers, battery products and brackets, etc.

     Cutting difficulties:
   1. In the blade shearing process, the aluminum powder in the plate is easy to fall off and stick to the blade. Over time, the blade is not sharp enough. Shorten the grinding cycle.
   2. The thickness of the aluminum plate is thin, 0.05mm, and even the thinnest is 0.04mm, so there are higher requirements for the accuracy of the blade, especially the requirements for flatness and parallelism.
   3. The width of the aluminum plate is large, the number of strips is large, and the cumulative error requirements of the blade are more precise, which has higher requirements for the thickness tolerance of the blade.
   4. In order to reduce the labor cost of changing the tool and save time, the service life of the blade is required to be higher .
