What is the difference between the high-speed punch press molds and the molds of ordinary punch presses

Punching machines and molds are precision differences, precision differences in price naturally different. A good horse with a good saddle, used in molds and punches are also applicable.

Difference in punching machine: ordinary punching machine bed structure is simple, rigidity is not enough, the table parallelism is poor. More with a single punch mold or product precision is not high mold. Ordinary price estimate of a few thousand dollars for the cheap.

The high-speed punch press bed structure is complex, solid, rigid enough, table parallelism 0.005MM, is currently the more high-end punch press, parallelism 0.02MM, a little worse, the price is in the hundreds of thousands. Most of the imported Japanese punch press in more than a million, Switzerland has more than 200 million, precision is not a little bit of a problem.

You asked about the mold, focusing on the mold, the most important part of the mold is the guide pillar, its guiding accuracy to determine the mold up and down the mold parts of the correspondence is accurate. Ordinary press mold general product precision is not high, so the precision of the mold parts will be much lower, guiding parts will naturally be reduced, such as the guide column, the use of round guide column and round guide sleeve, belongs to the round face with, but belongs to the gap with, according to different specifications of the unilateral gap of about 0.01mm -0.03mm; and high-speed punch press molds, the main product precision is relatively high, the amount of relatively large, the production of Long cycle, in order to maintain the convenience of the mold precision naturally want to improve a lot of comprehensive precision improvement, the most important is of course the guiding part, precision mold guiding part of the same time with the internal and external guide column, the current high-speed punching of the mold inside and outside the guide column is the guide column, the guide sleeve, with the way of the ball sleeve, the clearance is a rolling interference fit, the upper and lower die parts precision and position can be controlled in 0.002 0.005mm, the accuracy of the processed stamped parts can be guaranteed in +-0.01 to +-0.02.

Template different: different materials, ordinary molds and even with our common common steel plate, precision molds most of the current imported SKD11 materials, templates, precision thickness control of machining the larger difference in precision, precision mold plate requirements to be controlled in the 0.002- 0.005mm parallelism and parallelism and 0.005mm, the precision and thickness control, precision mold plate requirements to be controlled in the 0.002- 0.005mm parallelism and 0.005mm. 0.005mm parallelism and flatness, ordinary can reach 0.02mm is very good. Heat treatment is also different, precision molds are now commonly used in deep cold treatment, and even ultra-deep cold treatment to eliminate processing stress to make the template more stable and not deformed.

The processing of parts and materials are different, ordinary parts are more fast wire processing, accuracy of plus or minus 0.02, roughness; precision parts using slow-feeding processing accuracy of plus or minus 0.005 or less, the material, precision mold parts in order to be more durable, the use of tungsten steel as a part of the service life of the parts will be increased by several times.

Precision molds have a precision punch driven to show the advantages of precision molds: fast speed, good stability, high precision, easy maintenance. At present, high-speed common in 1000 times / minute, the product of different mold size and production speed will also have differences, 200 strokes above the common.

The difference is still a lot of places, for the time being, these, hope that you understand the differences in the mold to help.
