Namely the work of described hydraulic system provide hydraulic coupling that piston rod is outwards extended, thus promote web towards the direction movement and deformation away from hydraulic cylinder.
As the improvement of technique scheme, described flow controller comprises electromagnetic relay, two static contacts and the movable contact spring for conducting two described static contacts, described electromagnetic relay connects operating circuit and control circuit, two described static contacts are arranged on the inwall of described high-pressure liquid tube all at least partially, described movable contact spring to be movably set in described high-pressure liquid tube and to stop the liquid of described movable contact spring both sides mutually to circulate, two described static contacts access the both positive and negative polarity of described control circuit respectively, and described hydraulic system works asynchronously with described operating circuit.
Described hydraulic system works asynchronously with described operating circuit and refers to that, after described operating circuit is connected, described hydraulic system is started working; After described operating circuit disconnects, described hydraulic system quits work.
As the improvement of technique scheme, described electromagnetic relay is connection signal circuit also, and described signal circuit is provided with signal prompt mechanism.
Compared with prior art, implementation result of the present invention is as follows in the present invention:
Steel structure web arc means for correcting of the present invention, make steel structure web arc convex degree by the perception of piston rod institute by arranging flow controller, and hydraulic control system starts, hydraulic system provides hydraulic coupling that piston rod is moved and extrudes steel structure web arc convex portion, until lug boss smooth after, during piston rod work, the distance of movement equals lug boss and extrudes the displacement caused, and hydraulic system quits work automatically; Above-mentioned operation process automaticity is high, operating efficiency is high, labour intensity is low.

Detailed description of the invention
Below in conjunction with specific embodiments content of the present invention is described.
As shown in Figures 1 to 5, be steel structure web arc means for correcting structural representation of the present invention.Steel structure web arc means for correcting of the present invention, comprising: the electric-control system of several hydraulic systems and each hydraulic system of correspondence; Described hydraulic system comprises hydraulic pump 1, hydraulic cylinder 2 and is connected the high-pressure liquid tube 3 of described hydraulic pump 1 and hydraulic cylinder 2, the piston rod 21 of the hydraulic cylinder 2 of hydraulic system described in several is respectively in the two sides that steel builds material web 4, and the piston rod 21 that steel builds material web 4 two sides is symmetrical, is positioned at steel and builds the piston rod 21 of material web 4 any surface all along the width arrangement of steel structure material web 4; Described electric-control system comprises the flow controller 5 be arranged on described high-pressure liquid tube 3, and whether described flow controller 5 for controlling the work of described hydraulic system.Specifically preferably, described flow controller comprises electromagnetic relay 51, two static contacts 52 and the movable contact spring 53 for the described static contact 52 of conducting two, described electromagnetic relay 51 connects operating circuit 54 and control circuit 55, two described static contacts 52 are arranged on the inwall of described high-pressure liquid tube 3 all at least partially, described movable contact spring 53 to be movably set in described high-pressure liquid tube 3 and to stop the liquid of described movable contact spring 53 both sides mutually to circulate, two described static contacts 52 access the both positive and negative polarity of described control circuit 55 respectively, described hydraulic system works asynchronously with described operating circuit 54.
When work starts, as shown in Figure 1, movable contact spring 53 state in electric-control system as shown in Figure 4 for the state of hydraulic cylinder 2 piston rod 21, movable contact spring 53 makes two described static contact 52 admittances, namely control circuit 55 is admittance state, and electromagnetic relay 51 makes operating circuit 54 disconnect, and namely hydraulic system does not work.
Along with steel builds the movement of material web 4, as shown in Figure 2, boss touches piston rod 21, promote piston rod 21 to move, thus the liquid in hydraulic cylinder 2 is flowed, the liquid of flowing promotes movable contact spring 53 and moves in high-pressure liquid tube 3, state as shown in Figure 5, movable contact spring 53 makes two described static contacts 52 disconnect, namely control circuit 55 is off state, electromagnetic relay 51 makes operating circuit 54 admittance, namely hydraulic system is started working, hydraulic pump 1 pressurizes and piston rod 21 extruding promotion steel structure material web 4 is moved in hydraulic cylinder 2, the boss making steel build material web 4 caves in gradually, until smooth, along with the reset gradually of piston rod 21, now movable contact spring 53 is got back to again as shown in Figure 4 under state, thus make control circuit 55 admittance, electromagnetic relay 51 makes operating circuit 54 disconnect, hydraulic system quits work.In fig. 2, the hydraulic system worked particularly is that the right counts second, third and the 4th hydraulic system from top to bottom.
Further optimally, described electromagnetic relay 51 is connection signal circuit 56 also, and described signal circuit 56 is provided with signal prompt mechanism 57.By signalization circuit 56 and signal prompt mechanism 57, when operating circuit 54 admittance, when hydraulic system is started working, signal prompt mechanism 57 can send cue, operating personnel or automation equipment is made to stop Mobile steel building material web 4, until steel build the boss process of material web 4 smooth after, signal prompt mechanism 57 stops prompting, then continues Mobile steel and build material web 4.
Above content is detailed description made for the present invention in conjunction with specific embodiments, can not assert that the present invention specifically implements to be only limitted to these explanations.For those skilled in the art, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to the scope of protection of the invention.
