Introduction to the advantages and disadvantages of progressive dies

[Advantages of progressive die] 　　 1. High-efficiency advanced die can complete the blanking, flanging, bending, deep drawing, three-dimensional forming and assembly processes of complex parts, reducing intermediate transfer and repeated positioning, and the number of stations The increase in the production efficiency does not affect the production efficiency, and small precision parts can be punched. 2. The long-lived and complex inner shape and shape can be decomposed into simple convex and concave shapes, which are successively punched in sections. The process can be dispersed in several stations, and vacancies can be set in the areas where the processes are concentrated, thereby avoiding The problem that the wall thickness of the convex and concave molds is too small has changed the stress state of the convex and concave molds and improved the strength of the mold. In addition, the progressive die also uses a discharge plate as a punch guide plate, which is also very beneficial to improve the life of the die.　　3, high quality 　　The progressive mold completes all the forming processes of the product in one mold, which overcomes the constant operation and accumulated errors caused by multiple positioning when using a simple mold, and can effectively improve the quality of the product.　　4. Low cost. 　　 The progressive die has high production efficiency, a small number of presses, a small number of operators and a small workshop area, which reduces the storage and transportation of semi-finished products, so the comprehensive production cost of product parts is not high.　　5. Safety 　　 When the progressive die is punched, the operator does not need to reach into the dangerous area of u200bu200bthe die. For mass production, an automatic feeding mechanism is also used, and a safety detection device is installed in the mold.　　 [Disadvantages of progressive die] 　　 1. Progressive die has a relatively complex structure, high manufacturing accuracy, long cycle, and low material utilization, so the manufacturing cost is high.　　2. The progressive die is to punch out the inner and outer shape of the workpiece one by one. Each punching has a positioning error, and it is difficult to stably maintain the relative position of the inner and outer shape of the workpiece at one time.
