Detailed Description
Referring to fig. 1, the present application provides a technical solution: the digital hydraulic cylinder pressing device of the composite wire rod two-roller hot rolling mill comprises two rolling mill frames 1, wherein the two rolling mill frames 1 are connected through screws,
the bottoms of the two rolling mill frames 1 are connected with digital hydraulic cylinders 2 by bolts;
the bottom of the digital hydraulic cylinder 2 is attached with a rolling mill upper roller bearing seat 3;
the bottom of the rolling mill upper roller bearing seat 3 is attached with a rolling mill lower roller bearing seat 4.
Referring to fig. 1, a rolling mill frame 1 is connected to front and rear sides of a rolling mill upper roll bearing block 3 and a rolling mill lower roll bearing block 4 by screws.
Referring to fig. 1, a rolling mill base 5 is connected to the bottom of the rolling mill frame 1 by screws.
When the digital hydraulic cylinder pressing device of the composite wire rod two-roller hot rolling mill is used, the digital hydraulic cylinder 2 is adopted to replace a traditional hydraulic control system of an electric pressing device, and a stepping motor is used as signal output, so that a piston rod of the hydraulic cylinder moves completely according to the movement of the stepping motor, namely, the hydraulic cylinder does not step out and has thrust of hundreds of tons or thousands of tons. Therefore, by using a low-power control system, the large-scale machine can be digitally controlled, and hydraulic parts such as a direction valve, a speed regulating valve, a flow dividing valve and the like are saved. The cost is reduced. The system is simplified, the volume is reduced, and the accident rate is reduced. The hydraulic system is highly simplified, and only a hydraulic source consisting of an oil pump and an overflow valve (or a digital pressure valve) can be used in a connecting way without any complicated hydraulic elements such as a directional valve, a flow valve, a speed regulating valve, a one-way valve, a synchronous valve and the like. The installation integrated blocks of the valve elements are omitted, and electrical elements such as a travel switch, a relay and the like are not needed, and a plurality of sensors and control mechanisms are not needed, so that the vibration suppression effect on the vibration of the roller system can be realized.
