Non-standard flat washers, the icing on the cake precision for you +15 years of ingenuity, focus on powerful manufacturers

The dimensional accuracy of non-standard flat washers refers to the difference between the actual size of the flat washer and the design size. The smaller the difference, the higher the accuracy. In an ideal situation, the size of the blanking piece is the same as the size of the die edge, and the size of the punching piece is the same as the die edge size. Xiaoshuo will understand with you: In fact, due to the force of the workpiece during punching, a certain elastic deformation occurs. After the punching is completed, the workpiece will undergo elastic recovery, which will cause the size of the blank and the edge of the die. The size, punching parts and the punch edge size do not match, which affects the dimensional accuracy of the stamping parts. There are many factors that affect the dimensional accuracy of flat washers, such as blanking gap, die manufacturing accuracy, material properties and thickness, shape and size of stamping parts, etc. The main factor is the blanking gap. When the gap between the convex and concave dies is too large, the drawing effect of the material during the punching process is greater, so the drawing deformation is large. After the punching is finished, the size of the blanking part is reduced due to the elastic recovery of the material, while the size of the punching part is increased. When the gap is too small, compression deformation occurs due to the extrusion of the material by the convex and concave dies. After punching, the size of the blanking piece increases due to the elastic recovery of the material, while the size of the punching piece shrinks. The dimensional accuracy of stamping parts is also related to the nature and thickness of the material. Because the nature of the material directly determines the amount of elastic deformation of the sheet during the blanking process, softer materials have a smaller amount of elastic deformation, and the amount of elastic recovery after punching is also smaller, making the parts more accurate and harder. Material, the amount of elastic deformation is large, and the elastic recovery after punching is also large, so that the precision of the part is low. When the thin material is blanked, the elastic arch and the elastic recovery are also large, which makes the precision of the part low.
