The difference between sheet punching and pipe punching in the manufacturing process of stamping parts

There are many kinds of stamping parts manufacturing processes. Hardware stamping processing personnel should be familiar with and understand all stamping processes. Today, we are talking about the characteristics of plate punching and pipe punching. What is the difference? Hardware stamping manufacturers will take you to take a look; compared with the punching of sheet metal, although the deformation properties and characteristics of deformation have many similarities, because the pipe is hollow, the punching in the metal stamping process At that time, the pipe wall contacted by the concave and convex mold is an isolated surface, and the plate is a flat surface, so special process measures and mold structure forms are required; in hardware processing, pipe punching can be divided into two types: steel die punching and rubber die punching 1. The stamping process of the steel mold is to use the convex and concave molds made of tool steel to punch the pipe. According to the relationship between the movement direction of the punch and the movement direction of the press slider when the stamping die is working, the punching of steel molds can be divided into vertical punching and horizontal punching; 2. The punching process of rubber molds is Taking advantage of the easily deformable and non-dispersive properties of rubber, it is placed inside the pipe as an elastic punch instead of the steel punch, thereby punching the pipe wall; article recommendation: how to calculate cylindrical metal stamping What about the drawing force and pressing force of the piece?
