1、沖壓操作時,首先切換電磁換向閥,將預壓缸經預壓油道和工作缸上腔導通,然后經預壓進氣孔向預壓缸上腔通入氣壓,將預壓缸內的壓力油經預壓油道快速擠壓到工作缸上腔,推動工作缸缸桿快速伸出,使安裝在工作缸缸桿上的沖壓模具上模將工件快速頂靠在沖壓機床上的沖壓模具下模上,再切換電磁換向閥,將預壓缸經油道和增壓缸上腔導通,繼續經預壓進氣孔向預壓缸內通入氣壓,將預壓缸內的壓力油壓入增壓缸,將增壓缸內的增壓活塞向下壓縮,增壓缸下腔內的壓力油經增壓油道進入工作缸,對工作缸缸桿增壓,推動工作缸缸桿伸出,將鋼板沖壓成型。
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、在第一、二連接座之間連接螺栓拉桿,增強預壓缸和增壓缸結構穩定性,防止增壓缸和預壓缸漏油。
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、三連接座之間連接螺栓拉桿,增強工作缸結構穩定性,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.
氣體增壓泵
預壓式油壓氣液增壓器包括上下布置的第一、二、三連接座,在第一、二連接座之間設置預壓缸和增壓缸,在第二、三連接座之間連接工作缸,在第一連接座上設有預壓缸上腔的預壓進氣孔和通入增壓缸上腔的增壓進油孔,在第二連接座上設有通入工作缸的預壓油道、連通增壓缸下腔和工作缸上腔的增壓油道,在第二連接座上安裝電磁換向閥,電磁換向閥的進油口接入預壓缸內,電磁換向閥的其一出油口經油管和增壓進油口連接,另一出油口和預壓油道連接,在第三連接座上設有通入工作缸下腔的回位氣孔。其可將沖壓操作劃分為預壓和增壓兩動作過程,提高增壓出力,降低沖壓動作速度,作業安全可靠。
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.
