Mold a direct impact on the quality of high-speed presses
 
    We use high-speed presses, when maybe we only noticed the maintenance of high-speed presses and attention, in fact, supporting the high-speed presses mold is also very important. We must pay attention to the life of the reasonableness of the mold design and mold (ie punching times). A poor mold to customers is not immediately visible stamping products can fail, but sometimes invisible to an expensive high-speed presses bring fatal injuries. Poor mold guide sleeve with an outer diameter size of the error, the guide sleeve keyway axial dimension error, the die head and the punch is not perpendicular to the guide sleeve surface finish is not enough, the guide sleeve is harder than tool turret or tool turret inlay hardness, Such long-term and high-speed presses tilted head-grinding, long-term high-speed friction inevitably will die case hole grinding machine large. Of course, some high-speed presses can be replaced casement, some high-speed presses can not.
 
    High-speed punch die wheel up and down to check for mold base neutral regular basis. If the punch die neutral position is not good, resulting in mold rapid passivation, workpiece quality deteriorates. Should be checked and lubricated die holes and guide key on the turntable, if any damage promptly repaired; the lower die clean the turntable, so that the lower mold accurate installation and check for the key or keyway wear and replace if necessary; using a dedicated mandrel Calibration die station, if any deviation timely adjustment.
