    How long is the life of high-speed punch press mold? How to improve the life of the mold?

     If we want to know the service life of high speed press mold, we first need to know something about the composition of high speed press mold. The materials of molds are mainly divided into high-speed steel and tungsten steel, but Dongguan OREKU's high-speed press molds mainly use tungsten steel, and their manufacturing cost is between 30,000-100,000, sometimes even higher. A high-quality horse is matched with a high-quality saddle, and only when a high-end high-speed punch press is equipped with the right molds can it really show its unique appeal. The molds used in high-speed presses are manufactured through fast wire walking technology, and compared to the slow wire walking method used in low-speed presses, there is a significant difference between the two in terms of processing technology. If the customer has high requirements for the accuracy and smoothness of the dies, then the choice of slow-wire walking is essential, because the dies made by slow-wire walking processing technology can be finely trimmed to obtain better performance; using high-quality materials and expensive costs, the overall service life of the dies required for high-speed presses is as much as 3-5 times that of low-speed presses. Under normal operating conditions, the life of this die can be up to 5-10 years.
      Unlike conventional presses that use a single-punch die for single-punch processing, high-speed presses are typically manufactured at high speeds using the progressive dies that accompany them. Next, we will discuss how to extend the service life of progressive dies.high speed punch press

   1, to extend the use of small convex mold
     For those small convex molds whose diameters are equal to or less than the material thickness, we have set up a protection device for the continuous molds of high-speed presses with expanded sleeves. At the same time, we need to optimize the structure of the gap and leakage part of the small convex die of the high-speed press continuous die. Specifically, increase the double-sided clearance from the original 8% to 14-15%, change the shape of the concave die inserts, and set the height of the edge part of the size of the material thickness of 2-2.5 times to ensure that the roughness of the degassing part (taper) can reach Ral.6. This series of optimization measures can significantly extend the service life of the high-speed press continuous die.high speed punch press
   2、Improve the sharpening frequency of convex mold.
     In order to increase the number of times the convex mold can be sharpened and easy to load and unload, the high-speed press continuous mold with a new type of convex die fixing method. When fixed, the convex mold is not fixed with a fixed table, but with a small pressure plate fixed. Each grinding edge will be convex mold groove at the same time grinding down the same amount of sharpening, in the bottom of the convex die pad the same thickness of steel shims. This structure not only improves the number of sharpening times of the convex die of the continuous die of the high-speed press, but also makes it easy to disassemble and install.

       Through the above two convenient structure improvement, can make the original high-speed punch press continuous mold each grinding edge can only punch about 50,000 pieces of finished products, up to now each grinding edge can punch more than 100,000 pieces, some molds up to about 200,000 pieces. Greatly improve the production speed and economic efficiency.
