Abstract
The invention discloses a punching machine comprising a punching cylinder, a machine frame for installing the punching cylinder, and a punching model fixed on a piston rod of the punching cylinder. A protection mechanism which can prevent the punching model from sliding downwards is arranged between the punching model and the machine frame. The protection mechanism comprises a gear and a rack which are respectively installed on the machine frame and the punching model and meshed with each other, and further comprises an electromagnetic brake which is coaxially fixed with the gear. The electromagnetic brake synchronously gets or loses the power with an electromagnetic valve which controls the punching model to move forwards and backwards. The punching model is fixed on the piston rod of the punching cylinder through a stamping sliding plate. The electromagnetic brake and the gear are installed on a brake fixing pedestal at the same time. The brake fixing pedestal is fixed on the machine frame through an upper table plate which is correspondingly arranged on the punching sliding plate. One end of the gear movably passes through an upper limiting hole in the brake fixing pedestal to be meshed with the gear, and the other end of the gear is fixed on the punching sliding plate. The punching machine effectively prevents the punching model from sliding downwards in a punching gap and prevents the accidental injures of operators.
