The present invention relates to a multi-hole processing machine. More specifically, the present invention can form various sizes of holes without changing punching pins in the mold in accordance with the various sizes of creation. When the punching pin is damaged, the easily replaceable multi-hole manufacturing device has a plurality of grooves with a pin hole on the center with regular intervals on one side of the top and has an upper plate with guide hole. The punching pin with external side made of an elastic material is inserted in the pin hole of the upper plate. The guide hole of the upper plate and the inserted supporting material is installed in one side of the top. The other side of the top side has penetration hole corresponding to the pin hole of the upper plate. The lower part of the invention has a safety bump projected to the outside. The end of the safety bump has a lower plate part with an insert groove part connected to the penetration hole. The penetration hole of the lower plate has an elastic material of the punching pin. To have the punching pin inserted to one end, the upper end forms a short safety bump, and has a penetration hole in the middle. The external side of the lower end of the short safety bump has an inducing material with elastic material supporting the upper side of the lower plate in contact, and a plate-shaped controlling material which is detachable on the groove of the upper plate to control the pressure of the punching pin. |
