High speed punch presses and high speed molds

The precision of high speed punch presses and high-speed molds is different, and the difference between the precision of prices is naturally different. A good horse with a good saddle is also suitable for high-speed molds and high speed punching machines.
Punch difference: Ordinary punch presses have simple structure, insufficient rigidity, and poor parallelism of the workbench. Products that use a single punch or mold are not high-precision molds. The general price is estimated to be several thousand yuan cheaper.
The bed structure of the high-speed punching machine is complex, honest, and rigid enough. The parallelism of the worktable is 0.005mm. It is a high-end punching machine with a parallelism of 0.02mm, which is slightly worse, and the price is hundreds of thousands. Most of Japan's punch presses are imported at more than 1 million units, and Switzerland has more than 200 million units. The accuracy is not a small problem.
The most important part of the high-speed mold is the guide post, and the precision of the guide post determines the precision of the mold parts. Ordinary stamping dies generally have low product precision, so precision mold parts will be much lower, and guide parts will naturally be lower, such as guide posts, circular guide bushes and circular guide bushes, all of which are circular, but belong to the gap with the specification, according to Different specifications have different unilateral clearances. In 0.01mm-0.03mm; and high-speed dies, the product precision is high, relatively large, and the production cycle is long. In order to facilitate the maintenance of precision molds, it is naturally improved a lot. The precision of the inner guide column and outer guide column of the mold , At present, the high-speed die is still blank at home and abroad. The inside and outside of the guide post are guide posts and guide sleeves. The ball sleeve is used. The fit clearance is a rolling interference fit. The accuracy and position of the upper and lower modules can be controlled at 0.002-0.005mm, and the precision of the stamping parts after processing can be guaranteed at +0 Between .01 and +0.02.
Different molds: different materials, ordinary molds are even different from our ordinary ordinary steel, and most of the precision high-speed molds currently use imported SKD11 materials. In addition, the thickness control of mold processing accuracy varies greatly, and precision mold plates It is required to control the parallelism and flatness of 0.002-0.005mm, and it is generally good to reach 0.02mm. The heat treatment is also different. Precision molds are often used for cryogenic treatment, even ultra-cryogenic treatment, to eliminate processing stress and make the template more stable and free of deformation.
The processing of parts and different materials, ordinary parts are mostly processed by fast wire, the accuracy plus or minus 0.02, and the roughness; precision parts are mostly processed by stepping wire, the precision is plus or minus 0.005, the material and precision mold parts are more durable, and tungsten is used Steel is a part and its life will add severity. times.

Precision molds are driven by precision punches, which will show the advantages of precision molds: fast speed, good stability, high precision, and convenient maintenance. The current high speed has a total of 1000 times per minute, and the products and production speeds of different mold sizes will also be different.
