Introduction to the classification of stamping and drawing dies

With the development of the manufacturing industry and the improvement of people's quality of life, the variety of products and the complexity of the craftsmanship, the processing of any product is inseparable from molds. Today, stamping introduces the drawing die for everyone. The drawing die is a die that stretches and extends a flat plate to further change the shape and size. The drawing die is divided into two categories, 1. Single-action drawing 2. Double-action drawing The drawing die is divided into three parts: upper die (concave die), blank holder and lower die (punch die) 1. Single-action drawing die , Fixing and guiding on the machine tool, the punch of the single-action drawing die is fixed on the lower working table of the press, and the blank holder ring and the punch are guided. When the single-action drawing and stamping work, the air cushion of the machine tool is used to push up the blank holder to the specified height through the air lift rod, put the sheet, position, the machine goes down, the die moves to the height of the blank holder, and the die and the blank holder are compressed The die drives the blank holder ring to go down with it. When the machine tool reaches the closed height, the concave and convex molds are dead. After the drawing is completed, the slide block on the machine moves upward, the spring ejector pin pushes out the part, and the product part is taken out. 2. The double-action drawing die, the fixing and guiding of the parts of the double-action drawing die on the machine tool. The double-action drawing punch is fixed on the inner slide block of the press, the punch and the blank holder are guided, the blank holder is fixed on the outer slide of the press, the blank holder is guided by the die, and the die is fixed on The lower work surface of the press. When the double-action drawing die is stamping, the sheet is placed and positioned, the outer slide of the machine tool moves downwards, the blank holder goes down to the height of the die, the die and the blank holder press the material, the inner slide moves downwards, and the punch is closed Location, the concave and convex mold pierced dead. After the drawing is completed, the sliding block in the machine tool moves up, the cylinder pushes out the parts, and the product parts are taken out. There are many types of drawing parts, and suitable drawing dies should be selected for processing according to the characteristics of deformation mechanics.
