Abstract
The invention provides a punching machine which comprises a shell, a drive assembly, an eccentric shaft, an oil cylinder, a hydraulic pump, a push shaft, an upper punch die, a lower punch die and an oil return assembly. The drive assembly is arranged in the shell. The eccentric shaft is connected with the drive assembly. The oil cylinder is arranged in the shell. The hydraulic pump comprises multiple piston assemblies arranged in the circumferential direction of the eccentric shaft. Each piston assembly is provided with multiple oil holes communicating with the oil cylinder. The eccentric shaft rotates to drive the multiple piston assemblies to move in the direction perpendicular to the axis of the eccentric shaft, and oil in the oil cylinder is extruded into an oil cavity of the hydraulic pump. The push shaft is arranged in the shell and connected with the oil cavity of the hydraulic pump. After the oil enters the oil cavity, the push shaft moves in the direction where the lower punch die is located. The upper punch die is connected with the push shaft. The lower punch die and the upper punch die are oppositely arranged on the shell. The oil return assembly is connected with the push shaft, the oil cavity and the oil cylinder. After the push shaft moves to the limited position in the direction where the lower punch die is located, the oil return assembly is started, and the oil in the oil cavity flows back into the oil cylinder through the oil return assembly.
