Description
Technical field
This utility model is related to uncoiler design field, especially a kind of reel of uncoiler breathing quick change hydraulic cylinder.
Background technology
Existing Continuous Hot Dip Galvanizing Line reel of uncoiler breathing rotating hydraulic cylinder is typically all pushed away using breathing mandrel
Pull bar afterbody screws in the thread connecting mode of hydraulic cylinder piston club head, there is mandrel push-pull bar screw thread using this kind of design form
At escape, intensity is minimum, and operationally mandrel push-pull bar is acted on to mandrel head movement from hydraulic cylinder, while band moving sleeve does
It is easily tired in the case of being synchronized with the movement (by bonded between push-pull bar) screw thread frequently being drawn and pressed during mandrel harmomegathus
, then there is thread abrasion, fracture for a long time in labor.In dead load and little temperature change, threaded connection typically will not be automatic
Release.But in the case where shock and vibration, varying load effect or high temperature, temperature change are larger, in connection, pretightning force and frictional force gradually subtract
It is little, can all cause connection failure.
Existing hydraulic cylinder connected mode as Figure 1-3, is constituted including hydraulic cylinder 1, middle rotary drum 2 and mandrel 3, typically
Breathing mandrel push-pull bar afterbody is all adopted to screw in the thread connecting mode of hydraulic cylinder piston club head.
Found by studying, uncoiler rotating hydraulic cylinder subjects larger bending combined stress in uncoiling operation, and pushed away
When going out, the larger Normal hydraulic cylinder of stress is compared, and the rotating hydraulic cylinder of uncoiler loads larger (now at reel when being then and returning
In expanding state).In uncoiling process, as on uncoiler, coil of strip diameter constantly reduces, in rotating hydraulic cylinder rodless cavity oil
In the case of the continuous reduction of pressure holding, rotating hydraulic cylinder piston rod constantly rearwardly shrinks, and rotating hydraulic cylinder piston rod is connected with mandrel
Place, using gap it is big, have the connection of the coarse thread of impact.Under heavy load effect, mandrel pull bar connection screw thread will bear larger bending
Making a concerted effort for combined stress and axial thrust, necessarily causes frequently thread abrasion, fracture accident and frequently parts replacement operation.
And existing structure can cause the dismounting difficulty of mandrel and rotating hydraulic cylinder, reduce efficiency and production capacity is (general
The mandrel replacing construction of uncoiler needs 16 hours).
Thus, the reel of uncoiler breathing mandrel of prior art is main with the shortcoming that the connected mode of rotating hydraulic cylinder is designed
Show in terms of following three：
1st, dismantle inconvenient：As shown in figure 4, the mounting means of prior art rotating hydraulic cylinder is using rotary drum in the middle of monoblock type
3, rotating hydraulic cylinder, is wasted time and energy during dismounting using being threadedly coupled with mandrel.
2nd, bearing capacity is poor：The reel of uncoiler breathing rotating hydraulic cylinder of prior art is typically all pushed away using breathing mandrel
Pull bar afterbody screws in the thread connecting mode of hydraulic cylinder piston club head, as shown in Fig. 2 there is bearing capacity at mandrel tailing screw flight
The escape diameter of maximum is minimum, necessarily exacerbates the frequent phenomenon of rupture that the decline of its bearing capacity causes herein.
3rd, service life is short：The weak link of Fig. 2 mandrels effectively can not be strengthened, i.e., afterbody escape will necessarily be caused
The frequent generation of mandrel tail break accident, shortens its service life.
Utility model content
Technical problem to be solved in the utility model is to provide the uncoiling that a kind of bearing capacity is higher, dismounting is convenient
Machine drum-expanding quick change hydraulic cylinder.
Reel of uncoiler breathing quick change hydraulic cylinder disclosed in this utility model, including rotating hydraulic cylinder, middle rotary drum and
Mandrel, the middle rotary drum are connected on the housing of rotating hydraulic cylinder, and the mandrel is located in middle rotary drum and and rotating hydraulic
The piston rod of cylinder is connected, and the mandrel is connected using wafer type flange with piston rod, the connection end of the mandrel and piston rod
The bulge loop structure being adapted is respectively provided with, the wafer type flange includes two semicircle ring structures, is had on the inside of the semicircle ring structure
The bulge loop structure for having draw-in groove, the mandrel and piston rod is embedded in draw-in groove side by side, and two semicircle ring structures are connected with each other mandrel
Link together with piston rod.
Preferably, the middle rotary drum is split type structure vertically.
Preferably, 42CrMo steel of the material of the wafer type flange for modifier treatment hardness HB280-310.
The beneficial effects of the utility model are：
1st, the connected mode between rotating hydraulic cylinder piston rod and mandrel makes wafer type flange into by original being threadedly coupled
Connection design, need to only be directly loadable into accurate, quick location and installation by wafer type flange without the need for rotary core shaft；
2nd, the bearing capacity of this utility model mandrel and rotating hydraulic cylinder piston rod is enhanced, i.e., is subject in diameter of piston rod
On the premise of cylinder body diameter is limited, mandrel and piston rod are designed to into the wafer type flange connection of Fast Installation, are eliminated
The structure of Gewindefreistiche, revolutionizes the minimum phenomenon of the escape diameter of bearing capacity maximum on mandrel, increases
The strong bearing capacity of piston rod and mandrel；
3rd, in the middle of this utility model, the dissection type of rotary drum is designed, and can be reduced dismounting link and be realized quickly and accurately dismantling peace
Dress, makes this utility model rotating hydraulic cylinder and the replacing construction of mandrel shorten more than 3 times than current condition.
