Description
Technical field
The invention belongs to Rolling production technical field, relate to pinch roll device before roughing, particularly relating to a kind of by changing driving coupling mode with pinch roll apparatus before the energy-saving roughing reducing power consumption.
Background technology
In steel rolling mill's prior art, a pinch roll is all installed before roughing mills, for pinching the steel billet on roller-way to 1# roughing mill and making it nip smoothly.Before roughing, pinch roll has upper and lower two rollers usually, and lower roll is generally drive roll, and top roll is driven voller.For ensureing that steel billet can be nipped milling train smoothly, before roughing, pinch roll Speed Setting is have certain advanced argument than 1# rolling mill speed.When after pinch roll before steel billet to roughing, operating personnel send instruction, cylinder action, and before roughing, the top roll pressure of pinch roll, clamps steel billet, steel billet is sent into l# roughing mill together with lower roll.Top roll lifts by steel billet milling train exhaust hood of nipping, and completes and pinches action.After this, lower roll still need keep rotating and carry steel billet under motor drives.
Under normal circumstances, only at 1# mill roll or when changing groove, for solving steel billet skidding in 1# milling train, before former needs use roughing, pinch roll pinches, during subsequent production, before roughing, pinch roll only plays the effect of supporting, but must keep when drive roll contacts with steel billet rotating, motor will be in running status always, so just unnecessarily produce waste of energy, and lower roll roll surface tangential velocity is different from steel billet speed and produce skidding, also accelerate the wearing and tearing of roll surface, shorten the life-span of roller.
Summary of the invention
Running status will be kept to pinch roller motor before roughing when to overcome in prior art owing to normally producing always, produce too much power consumption waste, the object of this invention is to provide pinch roll apparatus before a kind of energy-saving roughing, this pinch roll apparatus is adopted to save energy consumption, it also avoid and the skidding that produce different from steel billet speed of roller roll surface tangential velocity in lower roll assembling, the corresponding wearing and tearing reducing roller surfaces simultaneously.
Object of the present invention is achieved through the following technical solutions:
Pinch roll apparatus before a kind of energy-saving roughing, it is characterized in that: this device comprises clamping and conveying device, transmission device and clutch apparatus, described clamping and conveying device comprises column, lower roller base, lower roll assembling, top roll assembling, upper roller seat, lift cylinder, entrance guide groove and lower roller base adjusting screw(rod), and lower roll erection is in lower roller base and be fixed on column; Top roll erection is in upper roller seat and be fixed on column; Lift cylinder is connected with upper roller seat, and lower roller base adjusting screw(rod) is arranged on below lower roller base; Described transmission device comprises motor, shaft coupling, reduction box, power transmission shaft; Described clutch apparatus comprises cylinder block, telescopic cylinder, shift fork, shift fork bearing, gear clutch body, and the shift fork bearing with lower roller base movement is fixed on the side of lower roller base; Telescopic cylinder is connected with clutch body by shift fork; Clutch body connects with transmission shaft flange.
In the present invention, shaft coupling is non-telescope universal coupling with spider.Clutch body is air cylinder driven gear clutch, comprise internal tooth flange, end cap A, end cap B, hole back-up ring, seal felt, oil scraper ring A, shaft end ring, bearing, spacer, oil scraper ring B, axle sleeve, external tooth cover A, seal cover A, slip teeth, seal cover B, external tooth cover B, internal tooth flange connects with the transmission shaft flange of transmission device, the roller spindle nose interference fit joint that external tooth cover A and lower roll assemble.
The present invention, by the roll surface height of lower roller base adjusting screw(rod) adjustment lower roll assembling middle roller, makes up the wearing and tearing of roller, keeps pinching center line constant; Roller in described lower roll assembling is drive roll; Described top roll realizes lifting action under being assemblied in the effect of cylinder, and the roller in described top roll assembling is driven voller.
When needing to connect, the piston rod of telescopic cylinder stretches out, and by shift fork, slip teeth is allocated to external tooth cover B, and slip teeth is engaged with external tooth cover A, external tooth cover B simultaneously, and clutch closes, and lower roll is assembled and joins together with the power transmission shaft of described transmission device.When disconnecting, the piston rod of cylinder shrinks, and by described shift fork, slip teeth is allocated to external tooth cover A, slip teeth is separated with external tooth cover B, throw-out-of clutch, lower roll is assembled and separates with the power transmission shaft of described transmission device.Limit switch is for detecting cylinder and stretch out and contraction putting in place signal.
When needs pinch steel billet, the piston rod of clutch cylinder stretches out, and clutch closes, and opens the roller in the assembling of motor driving lower roll; When not needing to pinch steel billet for a long time, close down motor, the piston rod of clutch cylinder shrinks, throw-out-of clutch, and the roller in lower roll assembling becomes free state.
The invention has the beneficial effects as follows: when needs pinch steel billet, the piston rod of clutch cylinder stretches out, and clutch closes, and opens the roller in the assembling of motor driving lower roll; When not needing to pinch steel billet for a long time, close down motor, the piston rod of clutch cylinder shrinks, throw-out-of clutch, and the roller in lower roll assembling becomes free state, thus realizes the object of economize on electricity; It also avoid and the skidding that produce different from steel billet speed of roller roll surface tangential velocity in lower roll assembling, the corresponding wearing and tearing reducing roller surfaces simultaneously.
