Description
Technical field
The utility model relates to the vertical looper of high-speed wire rolling equipment, particularly wire rod rolling.
Background technology
At present in high-speed wire mill, in order to the precision making product size tolerance reach higher, between frame, extensively adopt various forms of kink.Between the adjacent two frame plasticity milling trains in front and back, form the difference that certain metal flow surplus carrys out metal between replacement company's mill stand by this device, keep the stable of continuous rolling process parameter.
Existing vertical looper is made up of frame, hydraulic cylinder, even balance staff arm, wheel shaft pair.Wheel shaft pair is made up of Step Shaft, bearing block, duplex bearing, bearing cap, labyrinth seal, roller.Connecting balance staff arm is that Hydraulic Cylinder front swing arm drives the swinging axle in the sleeve block that is enclosed within and is fixed in frame to rotate, and swinging axle drives rear-swing arm to deflect.Rear-swing arm is that two axle sleeves conjunctions are fixed at connecting rod two ends respectively, front axle body is enclosed within swinging axle, another rear axle body is two half-watt synthesis, a half-watt is fixed on link end, two half-watts are fixed with four bolts by the slatted flange of half-watt, by a bearing block obvolvent therebetween, bearing block there are two termination flange limitings, Step Shaft rearward end is linked on the bearing in bearing block, cushion cover is had to isolate between two bearings, Step Shaft rear end face also locks with rear pressing cover, bearing block rear end face also locks with bonnet, Step Shaft stage casing is provided with labyrinth seal, Step Shaft leading portion is connected with stepped hole key in roller, a front gland is pressed in roller front step hole end surface stepped hole and locks with Step Shaft front end face, roller cylindrical is provided with arc ring groove.
Vertical kink effect is that connecting balance staff arm by Hydraulic Cylinder deflects overcurrent wire rod height between adjustment roller jack-up two frame finishing mill, makes overcurrent wire rod not be linearity, and becomes obtuse angle shape.The size at obtuse angle also makes the wire rod cross section of overcurrent wire rod between two frames, length changes, thus the Flow Velocity of crossing causing wire rod changes, section deformation, thus forms metal flow change.
Because the wheel shaft pair of vertical looper is yielding by overcurrent wire mount scrape along high temperature heat transfer, so service life is not long, often change; Break down and will process.But existing wheel shaft auxiliary structure is complicated, parts are too many, dismounting is complicated loaded down with trivial details; on-line operation then unit wants downtime longer; and operation of rolling off the production line first will take off wheel shaft pair, and to replace with wheel shaft for subsequent use secondary; but the secondary inner parts of wheel shaft are tightly fixed, and structure is too many, dismounting difficulty is comparatively large, the used time is longer; use duration equally during installation, affect On-line efficiency.Component structural is complicated, many with material, and the large technique of processing capacity is also complicated.
Summary of the invention
The utility model object, for overcoming above-mentioned defect, provides a kind of vertical looper of wire rod rolling.
The utility model scheme is: comprise frame, hydraulic cylinder, connect balance staff arm, wheel shaft is secondary, it is characterized in that: after the Step Shaft leading portion interval fit of wheel shaft pair fixes duplex bearing, be linked in Step Shaft axle head annular groove locate with shaft block ring; Roller is circle cap shape, and cylindrical is provided with arc ring groove, and roller inner circle stepped hole tight fit is enclosed within two bearing top circles; After the top, pipe box front end of a bearing cap is attached to bearing top circle rear end face, bolt through the ring flange of bearing cap screw up to implement in the tapped blind hole of roller rear end face both be fixedly connected with, bearing cap medium pore and Step Shaft stage casing cylindrical are in moving mated condition; The rear axle body connecting balance staff arm rear-swing arm is circle ring column, the back segment axle of Step Shaft moves in the rear axle body inner circle coordinating the company's of being inserted in balance staff arm rear-swing arm, after Step Shaft, axle head shaft block ring is linked in Step Shaft axle head annular groove and locates, the rear axle body connecting balance staff arm rear-swing arm is provided with radial screw bore, and in radial screw bore, the subsides bolt front end face top, top of fit is pressed on Step Shaft cylindrical.
The utility model has the advantage of: the secondary component structural of wheel shaft simplifies, and economizes on material, reduces costs, wheel shaft pair rolls off the production line dismounting, fast easy to assembly, enhances productivity.
accompanying drawing illustrates:
Fig. 1 is prior art structural representation.
Fig. 2 is the utility model structural representation.
detailed description of the invention:
The utility model structure comprises frame 4, hydraulic cylinder, connects balance staff arm 1, wheel shaft is secondary, it is characterized in that: after the Step Shaft 6 leading portion interval fit of wheel shaft pair fixes duplex bearing, be linked in Step Shaft 6 axle head annular groove locate with shaft block ring; Roller 8 is circle cap shape, and cylindrical is provided with arc ring groove, and roller 8 inner circle stepped hole tight fit is enclosed within two bearing top circles; After the top, pipe box front end of a bearing cap 7 is attached to bearing top circle rear end face, bolt through the ring flange of bearing cap 7 screw up to implement in the tapped blind hole of roller 8 rear end face both be fixedly connected with, bearing cap 7 medium pore and Step Shaft 6 stage casing cylindrical are in moving mated condition; The rear axle body 2 connecting balance staff arm 1 rear-swing arm 5 is circle ring column, the back segment axle of Step Shaft 6 moves in rear axle body 2 inner circle coordinating the company's of being inserted in balance staff arm 1 rear-swing arm 5, after Step Shaft 6, axle head shaft block ring is linked in Step Shaft axle head annular groove and locates, the rear axle body 2 connecting balance staff arm 1 rear-swing arm 5 is provided with radial screw bore, and in radial screw bore, the subsides bolt front end face top, top of fit is pressed on Step Shaft 6 cylindrical.
Dismounting that wheel shaft pair rolls off the production line is quick, as long as unclamp top to paste bolt, unload rear shaft block ring, wheel shaft pair deflection angle is avoided frame 4 space and stopped, just can take out from rear axle body 2 hole of rear swing arm 5, wheel shaft secondary with dynamic cooperation of rear axle body 2 accelerate handling speed, reduce former design tight fit and excessively use phenomenon.Roller 8 inner circle stepped hole tight fit is enclosed within two bearing top circles, saves a bearing block; Former design three lids, the design is only with a lid, and global design parts reduce, and Step Shaft 6 double end all uses shaft block ring.Take off bearing cap 7 after rolling off the production line, can conveniently take out roller 8 with specific purpose tool.Otherwise it is efficient and convenient to be too installed as reply technical process.
