The processing of sheet metal bending parts refers to the processing of changing the angle of the sheet or plate. Such as bending the sheet into V-shape, U-shape, etc. With its light weight, high strength and good performance, sheet metal bent parts are widely used in electronic and electrical, intelligent communication, automotive industry, medical equipment and other fields. Electrical conductivity.
However, during the processing of sheet metal bent parts, due to the influence of the mold, bending pressure and other factors, the bent sheets are often affected by indentation or scratches of different degrees, which affect the appearance and quality of the bent parts. So how to avoid this situation? If we want to avoid indentations, we need to find out the reasons for eliminating them.
Usually, both of these reasons will lead to indentation marks in the sheet metal bending parts during the process. Firstly, the mold is not cleaned in place, so we need to check whether there is waste on the surface or inside of the mold before the product is formed. Secondly, there is a problem with the structure of the V-slot of the mold. The larger the R angle of the V-groove of the die, the smaller the pressure between the plate and the shoulder of the V-groove of the die, the lighter the indentation, and vice versa.
