The specific embodiment
To combine accompanying drawing and embodiment that the present invention is done further detailed description below.
The present invention is a kind of Mannesmann piercing machine roll off angle regulating device, and is as shown in Figure 1, comprises Mannesmann piercing machine, hydraulic mechanism 3, position sensor 4, hydraulic motor 5, side pressure screw 6, leading screw 7, programmable controller 11 and man-machine interface 12.
The Mannesmann piercing machine comprises left roll 1 and right roll 2; Left side roll 1, right roll 2 are the cydariform roll; Left side roll 1 connects two hydraulic mechanisms 3 through two side pressure screws 6; Each hydraulic mechanism 3 connects between 5, two hydraulic mechanisms 3 of a hydraulic motor and connects through leading screw 7, and hydraulic mechanism 3 also connects a position sensor 4 respectively.
Right roll 2 is identical with the connected mode of left roll 1; Right roll 2 also connects two hydraulic mechanisms 3 through two side pressure screws 6; Each hydraulic mechanism 3 connects between 5, two hydraulic mechanisms 3 of a hydraulic motor and connects through leading screw 7, and hydraulic mechanism 3 also connects a position sensor 4 respectively.
Four position sensors 4 connect programmable controller 11, and programmable controller 11 connects man-machine interface 12.
Desired value through man-machine interface 12 input roll off angles exports desired value to programmable controller 11 after inciting somebody to action; Four position sensors 4 detect the physical location of four side pressure screws 6 respectively, and the physical location of side pressure screw 6 is exported to programmable controller 11, and programmable controller 11 obtains roll off angle value of feedback; Programmable controller 11 comparison object value and values of feedback, adjustment hydraulic mechanism 3 forms closed loop, and adjustment roll off angle value of feedback makes it consistent with roll off angle desired value.
