The working principle and the using flow of the invention are as follows: when the cold rolling-based yield lifting device is actually used, firstly, a machine body 1 is stably placed on the ground of a region to be worked, then each thread cylinder 315 is sequentially rotated, the rotation of the thread cylinder 315 drives the internal screw rod to displace through threads, the internal screw rod drives a push-pull sliding rod 318 to synchronously displace, the displacement of the push-pull sliding rod 318 drives a hollow plug 317 to slide along a flow guiding box 316, and the distance between each hollow plug 317 and a corresponding ejector rod 319 is adjusted according to the indication of a graduated scale 324, so that the distance between the hollow plug 317 and the ejector rod 319 is sequentially increased along the direction far away from a conveying roller 103;
in the material rolling process, as the movable roller 306 moves and drives the limit push rod 313 to synchronously move by using the connecting block 312, the limit push rod 313 drives the threaded cylinder 315 to synchronously move by using the linkage plate 314, the threaded cylinder 315 drives the hollow plug 317 to synchronously move by pushing and pulling the slide rod 318, the movable roller 306 and the hollow plug 317 synchronously move in the rolling process, and when the distance between the ejector rod 319 and the hollow plug 317 is zero in the rolling process, the movable roller 306 can not extrude materials any more, so that the forming thickness of the materials can be accurately limited by adjusting the distance between the corresponding ejector rod 319 and the hollow plug 317;
the maximum distance between the movable roller 306 and the fixed roller 308 is denoted as A, the distance between the hollow plug 317 and the corresponding ejector rod 319 is denoted as B, the value of B is the value of the downward displacement of the corresponding movable roller 306 in the rolling process, and the top end of the ejector rod 319 is flush with the top of the outer curved surface of the fixed roller 308, so that after the material passes through the space between the corresponding movable roller 306 and the fixed roller 308, the thickness dimension of the material becomes a corresponding difference value between A and B under the action of the corresponding movable roller 306 and the fixed roller 308, and the B is sequentially enlarged along the direction far away from the conveying roller 103 by rotating each thread cylinder 315, so that the material can be rolled step by step, the thickness dimension of the material after each stage of rolling can be precisely limited in the rolling process, the forming precision and stability of the material are greatly improved, the rolling qualification rate of the material is greatly improved, and the yield is further improved;
in the rolling process, the energy-collecting lifting unit 4 continuously sends the hydraulic liquid in the storage tank 419 into the diversion chamber 302, so that the hydraulic pressure in the diversion chamber 302 rises, under the action of the hydraulic pressure, the driving plate 303 drives the movable seat 305 to displace through the sliding rod 304, the movable seat 305 drives the corresponding movable roller 306 to synchronously displace, and the movable roller 306 can resist the material passing through the bottom of the movable roller;
in the process, the hollow plug 317 and the movable roller 306 synchronously displace, when the ejector rod 319 pushes against the corresponding flow limiting block 320 in the hollow plug 317, the flow limiting block 320 displaces to release the blockage of the flow blocking opening, at this time, the hydraulic liquid in the flow dividing chamber 302 enters the flow guiding box 316 from the flow blocking opening and then flows out of the flow blocking opening, and then enters the flow stabilizing chamber 310 from the communication hole, so that the hydraulic pressure in the flow stabilizing chamber 310 is the same as the hydraulic pressure in the flow dividing chamber 302, and further the hydraulic pressure can resist the limiting plate 311, the limiting plate 311 can give an upward pressure to the corresponding movable roller 306 through the limiting push rod 313 and the connecting block 312, and further counteract the hydraulic driving force born by the top of the driving plate 303, so that the movable roller 306 can not descend any more, the minimum distance between the movable roller 306 and the fixed roller 308 is limited, and the maximum rolling limit of materials is further realized;
in the above process, when the thickness of the material is rolled to a set value by the corresponding movable roller 306, the hollow plug 317 is in a conducting state, at this time, the hydraulic liquid in the storage tank 419 is continuously fed into the diversion chamber 302 and the steady flow chamber 310 by the energy-collecting lifting unit 4, and flows back to the storage tank 419 through the return pipe 323, the hydraulic pressure in the diversion chamber 302 and the steady flow chamber 310 is kept stable, meanwhile, the vibration in the rolling process is reduced by utilizing the diffusion buffer effect of the liquid, if the hydraulic pressure in the diversion chamber 302 is reduced due to unexpected factors in the process, the movable roller 306 is raised, the hollow plug 317 is also raised, the hollow plug 317 is in a non-conducting state at this time, the hydraulic pressure in the diversion chamber 302 is raised again, when the hydraulic pressure in the diversion chamber 302 is raised to the set value, the hollow plug 317 is in a conducting state, a negative feedback regulation mechanism of the hydraulic pressure is realized, and the direct regulation basis of the regulation process is the actual distance between the movable roller 306 and the steady flow chamber 308, namely the actual thickness after the material is rolled, and the rolling stability of the material is greatly improved;
in the rolling process, the output shaft of the driving motor 401 drives the conveying roller 103 to rotate so as to convey the material, the conveying roller 103 drives the synchronous wheel 402 to synchronously rotate through the driving wheel 404 and the driving belt 405, so that the fixed roller 308 synchronously rotates under the linkage action of the synchronous belt 403, the fixed roller is matched with the movable roller 306 to roll the material, and meanwhile, the driving wheel 404 drives the deflection disc 406 to synchronously rotate, and the deflection disc 406 drives the conversion head 411 to reciprocate through the driving column;
the displacement of the conversion head 411 drives the driving lever to deflect around the supporting column 408 through the universal joint 412, the driving lever drives the connecting lever to synchronously deflect through the resistance arm by using the limiting frame 410, the connecting lever drives the force application lever to synchronously deflect through the resistance arm by using the limiting frame 410, the force application lever drives the laminated lever to synchronously deflect through the resistance arm by using the limiting frame 410, the laminated lever drags the driving lever to deflect again through the resistance arm by using the limiting frame 410, and then under the limiting action of the supporting column 408 and the limiting frame 410, the four labor saving plates 409 synchronously deflect clockwise or anticlockwise, so that superposition circulation of driving force is formed, the driving force is amplified step by using the lever principle, and the force amplified four times acts on the force application end again, so that the driving force is circularly amplified, and each circulation can amplify the force four times, thereby greatly improving the stability and the sufficiency of the driving force;
in the force amplifying process, the conversion head 411 drives the driving lever power arm, i.e. the force application end, to reciprocate through the universal joint 412, the force application lever resistance arm, i.e. the force application end, then drives the linkage rod 417 to reciprocate synchronously through the deflection head 418, and then the linkage rod 417 drives the laminated plate 416 to reciprocate synchronously, and further under the current limiting guiding effect of the check valve 414, along with the reciprocating displacement of the laminated plate 416, the hydraulic fluid in the storage tank 419 can be continuously sucked into the energy collecting tank 413 through the conveying pipe 415, so that the system energy is overlapped and collected in the energy collecting tank 413 in a hydraulic mode, and after the hydraulic fluid reaches the hydraulic pressure required by rolling, the hydraulic fluid is conveyed into the hydraulic top seat 301 through the other conveying pipe 415, so as to provide sufficient hydraulic driving force for the quality improving and loss preventing unit 3.
