How to improve the strength of the punching die in Dalian

In order to improve the strength of Dalian stamping die, the final process of stamping die manufacturing requires finishing the surface of the mould to eliminate the tiny cracks on the surface of the die, and prevent the stamping die from being damaged by the enlargement of the crack during the strong impact of the press. The surface processing method of stamping die is fast and processing quality is good, except for the cavity with inner sharp angle and the narrow and deep cavity, it can be competent in other aspects.



In foreign countries has become the main process of stamping die processing, China is also in the active development. As the metal is deformed in the stamping die and the temperature increases, the EP oil base lubricants will become thinner, and in some cases the flash point or burning (smoke) will be reached. IRMCO polymer lubricants generally begin to be sprayed on a much lower consistency. As the temperature rises in the forming process, it becomes thicker and tougher.



There are pressing ring, press plate and so on. The blank holder can press the edge force of the drawing blank so as to prevent the billet from arching under the action of tangent pressure to form a wrinkle. The function of the press plate is to prevent the movement and bounce of the blank. The function of the ejector and discharge plate is to make it easy to make out the pieces and to clean the waste.



They are supported by a spring, rubber and air cushion push rod on the equipment. They can move up and down, and the top out part should have enough force and the movement should be limited. In order to improve the strength of stamping die, the final process of stamping die manufacturing requires finishing the surface of the mold to eliminate the tiny cracks on the surface of the die, and prevent the stamping die from being damaged by the enlargement of the crack during the strong impact of the press.
