Description
Technical field
The utility model belongs to belt steel rolling production equipment field, is specifically related to a kind of top pinch roll of hot-strip reels.
Background technology
Coiling machine is the terminal device of rolling after hot strip rolling system, and all size material hot-rolled strip production line is in the position of least significant end.The persistence technology precision of coiling machine directly determines quality and the lumber recovery of steel plate, and the critical component forming coiling machine is upper and lower pinch roll.Top pinch roll in taking-up equipment steel plate high temperature, high pressure, at a high speed, under sharp worn compound action, more easily produce wearing and tearing, chap, fall the failure modes such as block, and the inefficacy of top pinch roll can have a strong impact on the quality of steel plate, and the work period of taking-up equipment and production line.The structure of top pinch roll and roll surface wear-resisting are the keys improving pinch roll service life and maintain the permanent precision of pinch roll.
The top pinch roll of many hot-rolled strip production lines adopts the external technology introduced, for hollow-core construction, be made up of roller, main shaft etc., roller surface pile-up welding hard alloy, certain taper is made at roller two ends, one end is bolted to tapered sleeve on the flange of main shaft, flange is detachable, and its advantage is main shaft and roller convenient disassembly, can carry out reparation use by pair roller barrel, shortcoming is that complex structure manufactures assembly difficulty greatly, and namely preliminary use has loosening phenomenon to occur; Need frequent fastening bolt in production process, impact is produced, and the roller after repairing is because built-up welding hardened layer blockage effect is by roller and body of roll locking, thus can not realize changing the possibility that roller recovers precision.
Current top pinch roll roller is all generally a kind of two-layer composite, namely at the thick stainless steel of ordinary carbon steel roller shell outer surface built-up welding one deck 5 ~ 10mm or high-alloy steel.The advantage of this built-up welding pinch roll is that surfacing hardness is high, wearability good; Pinch roll can repeatedly repeated overlaying weldability.But hardfacing alloy pinch roll also exists many problems: one is pinch roll surface steel bonding, because overlay cladding and steel plate are all steel materials, can weld at the material of localized hyperthermia and pressure effect lower steel plate and on roll surface, produce steel bonding; Two is that resistance to impact is poor, and because overlay cladding is comparatively hard, when steel toe impacts, deformability is poor, produces local deformation or crackle; Three is that the working lining degree of depth is limited, needs frequent repeated overlaying weldability, affects production efficiency and output.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, provides a kind of structure simple, assembling and convenient disassembly, and roller material is individual layer, can simple and easy replacing roller, and the top pinch roll of the hot-strip reels of long service life.
The implementation method of the utility model object is, the top pinch roll of hot-strip reels, and roll shaft is a long solid shafting, and roller is cylinder; All there are endoporus and groove in described roller two ends, and the internal diameter of left end endoporus is greater than the internal diameter of right-hand member endoporus; The right baffle-plate welded with roll shaft and right baffle plate are placed in the endoporus of the left and right end of roller respectively; Left and right baffle plate is all symmetrically welded with two cuboid fixed blocks; Described cuboid fixed block extend out to outside left and right baffle plate, and the section of stretching out is placed in the groove of roller, and roller is limited on left and right baffle plate by fixed block.
During assembling the utility model, roller can move in direction from right to left side, and roller is welded and fixed block after loading again.During dismounting roller, first remove the fixed block on right baffle plate, can unload simply.
The utility model has the advantage of: when changing roller, left and right baffle plate maintains static, decrease the workload of dismounting baffle plate, only need dismounting, roller is installed; Roller can load and unload repeatedly, and assembling and replacing are conveniently; Roller adopts individual layer material-structure, heat-resistant antifriction, and good rigidity, can not produce thermal deformation because of built-up welding effect; Service life extends greatly.
The utility model structure is simple, and assembling and convenient disassembly, long service life, is with a wide range of applications in rolling metal plate and tape industry.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, roll shaft 1 is a long solid shafting, and right baffle-plate 3 and right baffle plate 5 are weldingly fixed on roll shaft 1, and roller 4 is cylinder, and all there is endoporus at roller 4 two ends, and right baffle-plate 3 and right baffle plate 5 are arranged in the endoporus of the left and right end of roller 4.
The single layer cylinder body of described roller 4 to be a thickness be 70 ~ 100mm.Roller 4 material is antiwear heat resisting cast iron or heat resisting steel.
Respectively there are an endoporus and two grooves in roller 4 two ends, and endoporus size and location and right baffle-plate 3, right baffle plate 5 are corresponding, and groove is corresponding with fixed block 2 section of stretching out.Roller 4 is limited on right baffle-plate 3 and right baffle plate 5 by the fixed block 2 at two ends.
The internal diameter of roller 4 left end endoporus is greater than the internal diameter of right-hand member endoporus, and the external diameter of right baffle-plate 3 is greater than the external diameter of right baffle plate 5, and roller 4 can move in direction from right to left side.
Right baffle-plate 3 and right baffle plate 5 are all symmetrically welded with two fixed blocks 2.Described fixed block 2 extend out to outside right baffle-plate 3 and right baffle plate 5, and the section of stretching out is placed in the groove of roller 4, plays location and the restriction of pair roller barrel 4.
