Abstract
The utility model discloses an improved upper pinch roller of a finish-rolling descaling box, which comprises a hollow roller body and two shaft heads, wherein a bushing part is arranged at one end of each of two shaft heads and has an outside diameter fitting with the inside diameter of two ends of the roller body; the bushing parts and the shaft heads form an integral structure by forging steel in the integral forging process; and lacing bar welding parts are arranged between the outer end surfaces of the bushing parts and the inner circumferences of two ends of the roller body. The improved upper pinch roller has simple structure, effectively enhances the connection strength between the shaft heads and the roller body, eliminates the phenomenon of welding defect between the shaft heads and the roller body, and ensures normal and orderly production.
Description
Technical field
The utility model belongs to the improvement of the smart De-scaling box clamp structure of hot-strip, relates to a kind of improved smart De-scaling box top pinch roll.
Background technology
The smart De-scaling box entrance and exit place of hot-strip is provided with top pinch roll respectively, and it is the hollow idler roller pattern of welded type.Top pinch roll is done lifting moving and is pinched roller gap with adjusting by the drive of hydraulic cylinder in framework window, the maximum opening degree 150mm of pinch roll, the size of opening degree by hydraulic cylinder with displacement transducer accurately locate.The effect of pinch roll has: flatten band steel nose, prevent to clash into nozzle, guarantee the rolled piece mm finishing mill unit of nipping smoothly; Bottom pinch roll motor band encoder, control roll rotor speed make between flying shear, pinch roll and the F1 finishing mill maintenance speed synchronous, when guaranteeing the flying shear back-end crop and strip speed synchronous; When finishing mill breaks down, after the shutdown, can strengthen the operating pressure of pinch roll hydraulic cylinder, steel plate is pulled out in bottom pinch roll motor counter-rotating simultaneously; Pinch roll has the effect of water shutoff to water under high pressure.The roller of top pinch roll is inserted and is welded by " spindle nose one ", " body of roll " and " spindle nose two ", and " spindle nose one " and " spindle nose two " also is respectively to be inserted by axle and cover to be welded.In actual production process, spindle nose and body of roll sealing-off and axle and the phenomenon of overlapping sealing-off often appear, and cause the top pinch roll axiality that dislocation takes place and form stall, cause disorderly closedown, the rolling rhythm of steel is with in influence.
The utility model content
The purpose of this utility model is to provide a kind of improved smart De-scaling box top pinch roll, it is simple in structure, is easy to manufacture, and can effectively strengthen the bonding strength between the spindle nose and the body of roll, eliminate the sealing-off phenomenon between the spindle nose and the body of roll, guarantee to produce and normally carry out in order.
The purpose of this utility model is achieved in that a kind of improved smart De-scaling box top pinch roll, comprise the hollow body of roll and two spindle noses, the first end of diaxon all has the cannula portion that an external diameter and body of roll two ends internal diameter are complementary, cannula portion and the spindle nose integrative-structure for being made of the forged steel solid forging is being provided with the lacing wire weld part between the internal perisporium at cannula portion outer face and body of roll two ends.
The utility model is simple in structure, be easy to manufacture, spindle nose and cannula portion are made integrative-structure, weld together by the lacing wire weld part and the body of roll again, change the suit Welding Structure of existing pinch roll, reduced the welding position, can strengthen the bonding strength between the spindle nose and the body of roll effectively, eliminate the sealing-off phenomenon between the spindle nose and the body of roll, guarantee to produce and normally carry out in order.Adopt the utility model structure, can reduce the fault rate of pinch roll greatly, reduce enterprise's production cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is that master of the present utility model looks cross-sectional view.
The specific embodiment
A kind of improved smart De-scaling box top pinch roll, as shown in drawings, left and right two spindle noses 1 that comprise the hollow body of roll 4 and be installed in the body of roll 4 two ends, two spindle noses, 1 one ends all have the cannula portion 3 that an external diameter and body of roll two ends internal diameter are complementary, cannula portion 3 and the integrative-structure of spindle nose 1 for being made of the forged steel solid forging are being provided with lacing wire weld part 2 between the internal perisporium at cannula portion outer face and body of roll two ends.Lacing wire weld part 2 is arranged continuously ringwise or is uniformly at intervals.The cross section of lacing wire weld part 2 is triangular in shape.
The utility model is simple in structure, has reduced the welding position, can strengthen the bonding strength between the spindle nose and the body of roll effectively, eliminates the sealing-off phenomenon between the spindle nose and the body of roll, guarantees to produce and normally carries out in order.
As further improvement of the utility model, be equipped with groove and fin respectively on cannula portion 3 outer peripheral faces and on the body of roll 4 two ends internal perisporiums, cooperate together by the concavo-convex of groove and fin between cannula portion 3 and the body of roll 4 two ends, thereby can prevent from effectively skidding to occur between the body of roll 4 and the cannula portion 3.
