The correct choice of drawing die structure for deep drawing parts, technology sharing

Many friends want to know the knowledge of deep drawing products, and hope to know some graphic materials or products about drawing dies, drawing processes, and deep drawing. Today, I would like to popularize the relevant technical parameters for everyone. The deep drawing/drawing process is one of the best in cold stamping dies. The technical difficulty coefficient is extremely high. The designer who can handle deep drawing has enough experience to control all kinds of stamping products easily. Let’s share with you the correct choice of the mold structure of the deep drawing/stretching part. 1. Correctly select the drawing direction. Deep drawing parts can be drawn into two types of continuous drawing: upward and downward (positive and negative drawing). It is recommended to use downward drawing for relatively low height drawing, with simple structure. When the stretching height is high, upward stretching is usually used, which is mainly convenient for feeding and product feeding stability. 2. How to choose the blank holder correctly. Generally, the first process of drawing parts requires independent blanking force or blank holder. The subsequent drawing process only needs to close the mold to ensure that the flange is flattened. 3. The selection of stripping structure is generally recommended to use an elastic stripping device. In order to ensure the stripping effect, rigid or semi-rigid stripping can also be used, but the space required for floating material needs to be left. The specific methods are as follows: Stripping structure Of course, the drawing mold is not clear in a few words, it needs actual combat, and it needs targeted practice to make good use of relevant knowledge points. For deep drawing products, especially slender drawing parts, repeated calculations and mold adjustments are required. In addition to the designer's need for superb skills, the requirements for mold adjustment and fitter masters are also high, and orders need to be taken cautiously.
