The double station vertical hydraulic punching machine adopts hydraulic drive punching. It is suitable for punching riveting holes of stainless steel / aluminum / copper utensils. It can punch a pair of riveting holes with a certain angle and distance at one time. The concave convex die installed on the two U-shaped drill bases can be replaced to change the diameter of the riveting hole. This machine has wide punching range, high efficiency, low cost and convenient adjustment.
