The invention discloses a hydraulic control loop of a cantilever-type recoiling machine pressing (ironing) roller device. The hydraulic control loop of the cantilever-type recoiling machine pressing (ironing) roller device comprises a hydraulic cylinder, a pipeline and a valve group, wherein the hydraulic cylinder is used for driving a pressing (ironing) roller; the valve group consists of an overflow valve, a throttling valve, a proportion pressure reduction valve, a pressure reduction valve, a second electromagnetic reversing valve, a first electromagnetic reversing valve and an oil circuit block; the hydraulic cylinder and the valve group are connected by the pipeline so as to form the hydraulic control loop. The hydraulic control loop of the cantilever-type recoiling machine pressing (ironing) roller device is reasonable, simple and reliable in design, can be used for setting different strip material compression forces, namely ironing forces, according to thickness variations of strip materials, eliminates strip material surface indentation, is obvious in strip mater ironing effect, is relatively good in quality, improves the strip material finished product rate, meets needs of users, and increases profits for enterprises further.
