Tension levellers are machineries designed for tension leveling works as integral for the flatness and shape requirements of the targeted materials. Tension levellers are often used to deal with sheet metals rather than metal wires, because sheet metals being de-coiled from the original coils form would normally go with unwanted curves that are not ideal for future processing.
For tension levellers, the action of tension leveling is the procedure of pulling the strip beyond the yield point to a permanent changed state so that the shape of the strip is formed as the process makes it flat.
There are many variations and problems may occur in the tension leveling process due to the countless possibilities may occur in the sheet materials. The tension leveler operators have to be able to deal with all the situations in time and make the feeding on time. If the sheet metals have an edge wave, the idea about how to solve the situation here by the help of tension leveller is to stretch the shorter fibers in the center of the strip part, so they will keep up with the length with the longer fibers from the edge wave phase. On the contrary, if the operators encounter a full center, then workers are trying to stretch the edges of the metal strip to match up in length with the center buckle part.
Besides, if the strip materials are consistent with the length across the width value of the strip materials, that mean onsite operators have successfully created flat steels already. The tension leveling process of tension levellers is a combination of several metal working processes, such as the elongating the strip materials, and the bending actions of the fibers over a series of the work rolls. In sum, tension leveling effects will eliminate the corresponding edge wave and the center buckle as well as to correct the lavish crossbows and coil sets. The design of tension leveling on the tension levellers concerns many metal working aspects, and the overall setting of the tension levellers are to be done only by professional tension leveling experts.
For the sheet metal to be leveled on the tension value, de-coilers are important parts that affect the whole working quality and the final outcomes. In the metal forming industry, coiler and de-coiler machines are widely used for roll slitting, which is a shearing operation that cuts a large roll of material into narrower rolls. De-coiler machines may also be referred to as un-coiler machines. There are two types of slitting methods, and the first one is log slitting and another is rewind slitting method.
For application, in log slitting process, the roll of material is treated as a whole unit, and one or more slices are taken from it without an unrolling or re-reeling process, therefore, in rewind slitting the web is unwound and run through the machine, which passes through knives or lasers, before being rewound on one or more shafts to form narrower rolls, and the multiple narrower strips of material may be known as MULTS or pancakes if their corresponding diameter is much more than their width scale. In the sector of metal perforating, there are a lot of perforated metal machines made in Taiwan that can perform excellent quality while grant massive quantity in a stable operational procedure.
Furthermore, de-coilers are not only used in the tension leveling on tension levellers only, but other tension leveling works, such as perforation process. There are many perforated metal machine suppliers manufacture different types of perforated metal machines and through continuous improvements to the feeding mechanism and punching moulds, their machines are able to meet customers’ processing demands for different perforation patterns and perforated metal applications. Many perforated metal machine suppliers are always happy to provide technical advices to customers based on their processing issues and help solve their production problems. There are large inventory of perforated metal machine models for customers such as plano type and C type perforated metal machines.
For plano type perforated metal machine, they are best for massive production manufacturing models focusing on high speed, larger capacity with similar mesh pattern requirements. Moreover, together with the optional Quick-Die-Change-System, the overall production performance will be greatly improved since the QDCS system will enable better performance with lower production costs as very effective supportive facility.
