The hidden danger that the maintenance personnel touches the button on the operating table during the maintenance process is avoided. In addition, the utility model has the advantages of simple structure, low cost and relatively convenient implementation.

However, when loading the punching machine, the raw materials to be punched are manually placed on the workbench, and then the upper die is pressed down to punch the raw materials by starting the operating table. When the operator is inattentive or the operation is too hasty, it is easy to be punched by the upper die, which brings danger to the operator. Moreover, the efficiency of this manual feeding method is also low during production, and cannot meet the requirements of mass production in some factories, so this solution needs to be improved.

Utility model content

Aiming at the deficiencies in the prior art, the utility model is to provide an automatic feeding device for a punching machine, which has the effect of being able to automatically complete the feeding work of raw materials and is easy to operate.
