Card punching device for preventing tool from broken

The invention relates to the technical field of card punching equipment, and discloses a card punching device for preventing a tool from broken. The device comprises a device body. A first electromagnet is fixedly connected to the top in the device body, a limiting bar I is fixedly connected to the bottom of the first electromagnet, a second electromagnet is connected in a limited manner outside the limiting bar I, a base is fixedly connected to the bottom of the second electromagnet, and a punch is connected in a limited manner to the bottom of the base through a pressing device. According tothe card punching device for preventing the tool from broken, the maximum descending depth of the punch can be controlled, the punch is protected and a condition that the surface of a product is damaged as the punch is broken and splashes as a result of too much feeding depth in a process of being in direct contact with the surface of a card is avoided, so that the time is saved, the production efficiency and quality of
