Abstract

The invention discloses an integrated speed-regulating hydraulic valve group. The integrated speed-regulating hydraulic valve group comprises a valve block, and further comprises a speed regulating mechanism, wherein a main oil inlet, a main oil return hole, a plurality of flow-dividing outlets and a plurality of flow-dividing inlets are formed in the valve block; the main oil inlet communicates with the flow-dividing outlets through a flow-dividing channel arranged inside the valve block; the main oil return hole communicates with the flow-dividing inlets through a confluence channel arrangedinside the valve block; the speed regulating mechanism is used for independently regulating flow speed of liquid in each flow-dividing outlet; and through the speed regulating mechanism which is usedfor used for independently regulating flow speed of liquid in each flow-dividing outlet, control over ejecting-out speed and punching speed in a hydraulic forming press can be realized, so that the problems such as ejecting deviation or hole collapse caused by too great speed difference of the flow-dividing channel are avoided.

Description

technical field [0001] The invention relates to the field of valve control, in particular to an integrated speed-regulating hydraulic valve group. Background technique [0002] The existing integrated speed-regulating hydraulic valve group uses the branch channel and the confluence channel to realize the branching of the hydraulic oil, and the flow rate of each oil channel is equal, and the difference of the oil inlet speed is uncontrollable, which is not conducive to the hydraulic forming press. It is pointed out that the control of punching speed will cause problems such as top deviation and hole collapse caused by excessive speed difference. [0003] Therefore, in order to solve the above problems, an integrated speed-regulating hydraulic valve group is needed, which can control the ejection and punching speed in the hydroforming press, and avoid problems such as top deviation and hole collapse caused by excessive speed differences in the runners. .
