[0043] In this embodiment, the present invention inputs control instructions through the instruction transmitting device 101, and wirelessly transmits the control instructions to the PLC control device 102, so that after receiving the control instructions from the instruction transmitting device 101, the PLC control device 102 can control the roll changing operation module 104 or the material pressing operation module 105 according to the control instructions, thereby realizing the automatic operation of roll changing and material pressing nearby, which solves the problem that when the existing high-speed wire rolling mill needs to operate the roll changing and material pressing operations on the operation box, because the operation box is far away from the rolling mill, it is inconvenient to view the real-time situation during operation, resulting in low efficiency of roll changing and material pressing operations. At the same time, the equipment status cannot be confirmed in time, and it is easy to cause misoperation and cause safety accidents.

[0044] The instruction transmitting device 101 is connected to the PLC control device 102, and the PLC control device 102 is connected to the roller changing operation module 104 and the material pressing operation module 105 respectively;

[0052] Again, the remote control 106 is provided with an emergency stop button, a start button, a rack switching button, an ascending button, a descending button, a clamping button, an open button, a forward button, a backward button, a pressing button and a discharge button. After the emergency stop button is pressed, there is no action output by pressing the start button, the rack switching button, the ascending button, the descending button, the clamping button, the open button, the forward button, the backward button, the pressing button or the discharge button. The operation can be performed by pressing the start button. After that, pressing the "ascending button" will perform the ascending action, pressing the "descending button" will perform the descending action, pressing the "clamping button" will perform the clamping action, pressing the "open button" will perform the opening action, pressing the "forward button" will perform the forward action, pressing the "backward button" will perform the backward action, and pressing the "pressing button" will perform the pressing action.

[0057] The hydraulic cylinder 111 is used to drive the roller to rise, fall, clamp, open, advance and retreat, so as to realize the roller changing operation.

[0058] In addition, the control valve body 110 includes a lifting valve 115, a transverse valve 116 and a clamping valve 117. The lifting valve 115, the transverse valve 116 and the clamping valve 117 are all connected to the same oil pump 109, so that one oil pump 109 controls multiple valve bodies.

[0059] In addition, the hydraulic cylinder 111 includes a lifting cylinder 118, a transverse cylinder 119 and a clamping cylinder 120.

[0062] The pressing motor 114 is used to drive the rollers to perform rough rolling or finish rolling on the steel to achieve the pressing operation.

[0063] When using a material pressing wireless remote control operating system of the present embodiment, the operation can be performed by pressing the start button, and then pressing the "up button" to perform the up action, pressing the "down button" to perform the down action, pressing the "clamp button" to perform the clamping action, pressing the "open button" to perform the opening action, pressing the "forward button" to perform the forward action, pressing the "backward button" to perform the back action, and pressing the "material pressing button" to perform the material pressing action. At this time, the remote controller 106 will encode the relevant information of the corresponding button, and convert it into a wireless signal after modulation and send it out. After that, the wireless signal from the remote controller 106 is received by the remote control receiver 107, and the wireless signal is amplified and decoded to obtain a control signal. Subsequently, the control instruction corresponding to the control signal is wirelessly transmitted to the PLC control device 102. When the PLC control device 102 receives the control instruction, the PLC control device 102 will control the oil pump contactor 108 or the inverter contactor 112 to be connected or disconnected according to the control instruction.

After that, the lifting cylinder 118, the transverse cylinder 119 or the clamping cylinder 120 are driven to rise, fall, clamp, open, move forward and backward respectively through the lifting valve 115, the transverse valve 116 or the clamping valve 117, so as to realize the automatic operation of roller changing. When the frequency converter contactor 112 is connected, the frequency converter 113 starts, so that the frequency converter 113 can drive the pressing motor 114 to start, stop, move forward and reverse, thereby driving the rollers to perform rough rolling or finish rolling operations on the steel, thereby realizing the automatic operation of pressing.

[0065] When a fault occurs during roller replacement or pressing, pressing the emergency stop button on the remote control 106 and then pressing any other button will result in no output, thereby stopping the movement of the pressing motor 114, the lifting cylinder 118, the transverse cylinder 119 or the clamping cylinder 120 to facilitate maintenance of the fault.
