The invention discloses a punch device for producing keyboards. The punching device for producing keyboards comprises a drill press spindle and a power supply unit, and further comprises a connectingtube and a driving unit, wherein the power supply unit is used for running of the drill press spindle; a drill bit which is detachably connected with the drill press spindle is arranged on the bottomof the drill press spindle; the cross section of the drill bit is in the shape of a frustum; the diameter of the lower surface of the drill bit is twice that of the upper surface of the drill bit; thedrill press spindle has a hollow structure; wind gaps are formed in two sides of a drill press; a through tube is arranged in the drill press spindle; two branch tubes which communicate with the through tube are arranged at one end of the through tube; the branch tubes communicate with the wind gaps; a rotating joint is arranged on the drill press spindle; a cavity is formed in the rotating joint; a discharge hole which communicates with the cavity is formed in the rotating joint; the other end of the through tube communicates with the cavity; a piston box is arranged on one side of the drillpress spindle; the piston box communicates with the discharge hole through the connecting tube; a piston rod is arranged in the piston box and is connected with a driving unit; and the driving unit is used for driving the piston rod to move along the piston box in a reciprocating manner. Viscosity can be gradually reduced by centrifugal force and under the state of heating, and thus, the punch device for producing keyboards cannot be adhered to the drill bit.
