The following detailed description of the preferred embodiments of the present invention will be provided with reference to fig. 1, so that the advantages and features of the present invention can be easily understood by those skilled in the art, and thus, the protection scope of the present invention can be defined more clearly and clearly.

In order to promote the mobility and the stability of the die-cut process of numerical control, this novel die-cut system of numerical control, the system is whole by PLC control panel control action, and concrete structure is: an oil pump 8 in an oil tank 1 is connected with a bell jar and a three-phase vertical motor 7 through a pump connection bell jar, a first integrated block is arranged on the oil tank and is respectively connected with a second integrated block, a third integrated block, a fourth integrated block and a fifth integrated block through hydraulic hoses, a group of oil inlets and oil outlets are respectively arranged on the second integrated block, the third integrated block, the fourth integrated block and the fifth integrated block and are respectively correspondingly connected with four punching oil cylinders 17, a pump shaft of the oil pump 8 is connected with an output shaft of the three-phase vertical motor 7 through a coupler, the three-phase vertical motor 7 is arranged on an oil tank panel 18, hydraulic oil is pumped out through the oil pump 8 and then is conveyed to oil outlets on other integrated blocks through oil passages in the first integrated block and finally is conveyed into oil passages of the corresponding punching oil cylinders 17, a one-way valve 9 and an electromagnetic overflow valve 10 are arranged on the first integrated block, the third integrated block and the fourth integrated block, and the fifth integrated block, and are sequentially provided with an electromagnetic, The hydraulic control one-way valve 14 and the one-way balance valve 15, and the electromagnetic directional valve 13 is used for regulating and changing the flow direction of the hydraulic oil; when the electromagnetic directional valve 13 is positioned in the middle position, the hydraulic control one-way valve 14 is closed to tightly seal oil in two cavities of the hydraulic cylinder, and at the moment, the piston cannot move due to the action of external force, so that the aims of locking an oil way and stopping the circular flow of hydraulic oil to position the punching oil cylinder 17 are fulfilled; the function of the one-way balance valve 15 is that when the oil cylinder is in an extending state, the one-way balance valve 15 acts to generate back pressure for a rod cavity of the oil cylinder, so that a piston rod of the oil cylinder is balanced when extending.

An oil filling port and a liquid level thermometer 4 are arranged on the oil tank 1.

In order to ensure the cleanness of return oil, an oil return filter 5 is arranged at an oil return opening of the oil tank 1, and in order to prevent the hydraulic oil circulating in the system from generating high temperature, an air cooler 16 is arranged on an oil return pipeline.

In order to ensure that no residue is left in the hydraulic oil pumped out by the oil pump 8, an oil suction filter 2 is arranged at the hydraulic oil inlet end of the oil pump 8.

And a pressure gauge 12 is arranged on the first manifold block, the pressure gauge 12 is communicated with an oil way in the first manifold block, and a pressure gauge switch 11 is arranged on a connecting passage of the pressure gauge 12.

The specific working principle is as follows: referring to fig. 1, firstly, the electromagnetic valve on the electromagnetic overflow valve 10 is de-energized, then the three-phase vertical motor 7 is energized to start, the oil pump 8 is driven to rotate, high-pressure hydraulic oil is output through the first integrated block, and when the motor is started to be balanced, the electromagnetic valve on the electromagnetic overflow valve 10 is electrified to build the system pressure. The hydraulic oil reaches the valve ports of the electromagnetic directional valves 13 on the corresponding oil paths of the punching oil cylinders 17 through the check valves 9, and the electromagnetic directional valves 13 are powered when the punching oil cylinders 17 need to be extended out, and the corresponding electromagnetic directional valves 13 need to be powered when the punching oil cylinders 17 in the four groups work. The left cavity oil circuit of the electromagnetic directional valve 13 is communicated, hydraulic oil passes through the hydraulic control one-way valve 14 and the one-way balance valve 15 in sequence and is finally sent into the oil cavity of the punching oil cylinder 17 to enable the piston rod to extend out to complete punching action, and meanwhile, the one-way balance valve 15 plays a role together to increase certain back pressure for the rod cavity in the corresponding oil cylinder to enable the oil cylinder to operate in balance when the oil cylinder descends.
