1、冲压操作时，首先切换电磁换向阀，将预压缸经预压油道和工作缸上腔导通，然后经预压进气孔向预压缸上腔通入气压，将预压缸内的压力油经预压油道快速挤压到工作缸上腔，推动工作缸缸杆快速伸出，使安装在工作缸缸杆上的冲压模具上模将工件快速顶靠在冲压机床上的冲压模具下模上，再切换电磁换向阀，将预压缸经油道和增压缸上腔导通，继续经预压进气孔向预压缸内通入气压，将预压缸内的压力油压入增压缸，将增压缸内的增压活塞向下压缩，增压缸下腔内的压力油经增压油道进入工作缸，对工作缸缸杆增压，推动工作缸缸杆伸出，将钢板冲压成型。
1, stamping operation when the first switch electromagnetic valve, the pre pressure cylinder by pre pressing oil cylinder and the work is conducted, and then the pre pressure intake hole pressure to pass into the pre pressure cylinder, the pressure oil cylinder by preloading preloading of oil cylinder to work fast extrusion cylinder rod chamber, push the work fast out, which is mounted on the cylinder rod of the stamping die mold will work against the workpiece fast stamping die stamping machine in the mold, then switch electromagnetic valve, the pre pressure cylinder through a cavity oil passage and a pressure cylinder through the pre pressure, continue to the inlet pressure to pass into the pre pressure cylinder, the pre pressure cylinder pressure oil into the pressure cylinder, the booster piston cylinder downward pressure, oil pressure cylinder in the subarachnoid space by pressurized oil into the cylinder, pressure of cylinder rod, cylinder cylinder rod pushes out the steel plate punch Type.

2、在一、二连接座之间连接螺栓拉杆，增强预压缸和增压缸结构稳定性，防止增压缸和预压缸漏油。
2, the bolt pull rod is connected between the first, second connecting seats to enhance the structural stability of the pre pressure cylinder and the pressurized cylinder, so as to prevent the oil leakage of the pressurized cylinder and the prepressed cylinder.
3、在第二、三连接座之间连接螺栓拉杆，增强工作缸结构稳定性，防止工作缸漏油。
3. The bolt pull rod is connected between the second, third connecting seats to enhance the structural stability of the working cylinder and prevent the oil leakage of the working cylinder.
预压式油压气液增压器包括上下布置的一、二、三连接座，在一、二连接座之间设置预压缸和增压缸，在第二、三连接座之间连接工作缸，在一连接座上设有预压缸上腔的预压进气孔和通入增压缸上腔的增压进油孔，在第二连接座上设有通入工作缸的预压油道、连通增压缸下腔和工作缸上腔的增压油道，在第二连接座上安装电磁换向阀，电磁换向阀的进油口接入预压缸内，电磁换向阀的其一出油口经油管和增压进油口连接，另一出油口和预压油道连接，在第三连接座上设有通入工作缸下腔的回位气孔。其可将冲压操作划分为预压和增压两动作过程，提高增压出力，降低冲压动作速度，作业安全可靠。
The pre pressure hydraulic gas-liquid supercharger comprises an upper and a lower connecting seat arrangement first, second, third, in the first, second connecting seat is arranged between the pre pressure cylinder and the pressure cylinder, the connecting seat second, third is connected between the working cylinder, pressure inlet and pass into the upper cavity of the pressure cylinder pressure oil inlet hole in the seat is provided with a pressure cylinder connected to the first in the second pre connected through cylinder pressure oil passage, communicated with the pressurized oil cavity tract pressure cylinder cylinder is provided with a cavity and work, in second is connected with the electromagnetic valve installation seat, inlet access pre pressure cylinder solenoid valve, solenoid valve and the oil outlet through tubing and booster oil inlet connection, another oil outlet and pre pressure oil is connected between the third connected through the return cylinder lower seat is provided with a hole. The stamping operation can be divided into two action process of pre pressure and supercharging, which can improve the pressure output, reduce the stamping action speed, and the operation is safe and reliable.
