The invention relates to a key
punching device, and particularly relates to an accurate key
punching device for hardware manufacturing. The technical problem to be solved by the invention is to provide an accurate key
punching device for hardware manufacturing, which is accurate in punching. In order to solve the abovementioned technical problem, the invention provides an accurate key punching device for hardware manufacturing. The accurate key punching device for hardware manufacturing comprises a left support frame, a bottom plate, a right support frame, a support seat, a spring, a first slide block, a fan, a first slide rail, a first fixed
pulley, a stay wire, a second fixed
pulley, a third fixed
pulley and the like, wherein a screen groove is arranged below the right side in the left support frame, an
electromagnet is arranged at the bottom of the screen groove, a third slide rail is arranged above the right side in the left support frame, a third slide block is arranged on the third slide rail, and a second rack is arranged on the third slide block. The accurate key punching device for hardware manufacturing, which is disclosed by the invention, achieves the purpose of accurate key punching for hardware manufacturing.
