Several manufacturing factors affecting the quality of slitting circular knife during use
There are many manufacturing factors that affect the quality of the slitting knife during use, including the material processed by the slitting knife, the environment in which it is used, the precision of the equipment, and the maintenance and maintenance during use. Among them, the size of the sheet to be cut And materials are especially critical, and users need to choose the manufacturing material of the blade according to the different cutting purposes, which is the most economical method.
In the production process of the slitting circular knife, the forging quality of the material, the standardization of the machining process and the quality of the heat treatment are very important. Among them, forging can make the product obtain a more dense metal structure, high-quality heat treatment can ensure the product has a stable hardness, and the advanced nature of the finishing process is a prerequisite for product accuracy assurance. If the blade manufacturer can handle all the above processes properly, the durability of the product will be guaranteed.
At present, the techniques used by different companies in the manufacture of slitting circular knives are extremely rich. From the choice of materials, the technical aspects of forging have different knowledge. For example, the mechanical properties of forged materials are due to rolling. The billet, especially the knife that has not been forged, has poor heat treatment stability, and often has the problem of quality of chipping and cracking. Due to the unreasonable design of the process, the products of the same material have different qualities. There are quality problems such as breakage during use.
In terms of the edge slope value of the slitting circular knife, a reasonable shear angle with a certain gradient of the cutting edge can be more conducive to the sheet shearing, and an excessively large shearing edge can cause the rigidity of the slitting circular knife to be insufficient. The occurrence of deformation or cracking of the cutting edge occurs from time to time. Therefore, if the accuracy and design of the product are improper, it is easy to have such problems. Therefore, the company must have certain recognition ability to be able to purchase better slitting ciruclar knife.
