Description
Technical field
The present invention relates to thin-belt casting rolling production line, more particularly to coiling machine, the more particularly to coiler mandrel for thin-belt casting rolling.
Background technology
Being used at present country's reeling tube of reeling without interior water cooling pattern, reel relies primarily on outer cold water cooling, to protect more
When being batched under 600~800 DEG C of high temperature of card, parts do not produce failure, just there is stricter limitation to the time of batching.
Also, the thin-belt casting rolling for belt steel thickness in 0.7~1.91mm is batched, the maximum volume-weight 32.8t of reel is maximum
Coil diameter 2050mm, the time of batching for up to arrives about 17min, to ensure reel normal work, it is necessary to reel is carried out effectively cold
But, that is, water cooling in increasing.
Water cooling wedge plunger type mandrel is primarily present following technical problem in existing hot rolling coiler：
Firstly, since internal water cooling fanning strip, which is operated in alternation, batches stress and the coefficient complex stress shape of thermal stress
Under state, early stage is based on wear out failure, and stage is likely to occur cracking failure even fracture failure, because fracture failure can cause
More serious production accident, therefore lower machine is just needed when there is long deep torn grain on fanning strip, judge to scrap.Therefore it is general by fanning strip
Material is set to the material of good toughness (relative " soft ").After beginning is batched, fanning strip and big plunger and wedge-shaped between centers can produce compared with
High contact stress, while auto-necking and secondary swollen footpath function can be such that fanning strip occurs relatively with big plunger in the course of the work
Slide, the fanning strip of this homogenous material would become hard to while meeting wear-resisting and good toughness requirement.
Secondly as strip can produce the dynamic loading along spool axis direction, and auto-necking and two in coiling process
Secondary breathing function can make fanning strip diametrically produce dynamic mobile, therefore sector shaft can be by larger dynamic and static to confined planes
Frictional force, under the collective effect of heavy wear and alternate stress, the axially position gib head of fanning strip easily fails.
Again, coupled between outrigger shaft and main shaft using split assembling, the two coordinates by axle, hole realizes radial constraint；By
Bolt-connection realizes axial constraint.In coiling process, the attachment bolt and screw of the two are in alternation tension and compression stress state, and fan
The replacing of shape plate is also required to dismounting outrigger shaft and axial restraint bolt, therefore, the tapped blind hole of connection herein easily fail.

In an optional example of the invention, as shown in Fig. 2 plunger assembly 400 includes the first plunger 410 and the second post
Plug 420, the diameter of the first plunger 410 is more than the diameter of the second plunger 420, and the first plunger 410 and the second plunger 420 are arranged in
Between fanning strip 310 and wedge-shaped axle 100, the axial direction of the first plunger 410 and the second plunger along wedge-shaped axle 100 is arranged side by side and had
Interval, the first plunger 410 and the second plunger 420 are disposed as one end contact on tapered ramp 110, and the other end runs through main shaft
200 side wall and contact is on the internal face of fanning strip 310, and the internal face of fanning strip 310 is in the first plunger 410 and the second plunger
The first build-up wear-resistant layer 320 is equipped with the position of 420 corresponding matchings.
In an optional example of the invention, as shown in Fig. 2, Figure 10, offered on the side wall of main shaft 200 and the first post
Fill in the first plunger hole 290 of 410 corresponding matchings and the second plunger hole 280 with the corresponding matching of the second plunger 420.Each group
One plunger hole 290 and the second plunger hole 280 correspond to a tapered ramp 110 on wedge-shaped axle 100, each tapered ramp 110
The corresponding plunger hole 280 of first plunger hole 290 and second is arranged on the same line, the first plunger hole 290 and the second plunger
Radial positioning effect is played to the first plunger 410 and the second plunger 420 respectively in hole 280.One end contact of first plunger 410 is in wedge shape
On inclined-plane 110, the other end of the first plunger 410 passes through the first plunger hole 290 and contact is on the internal face of fanning strip 310, the
One end contact of two plunger 420 is on tapered ramp 110, and through the second plunger hole 280, simultaneously contact exists the other end of the second plunger 420
On the internal face of fanning strip 310, disk spring 430 is configured with the second plunger 420.Batch before beginning, in the second plunger 420
Disk spring 430 is in compressive state, exists and promotes trend of the fanning strip 310 away from wedge-shaped axle 100.
In an optional example of the invention, as shown in Fig. 2, Fig. 6, Figure 10, Figure 13 to Figure 17, the first plunger 410
Top surface is plane, and the bottom surface of the first plunger 410 is the inclined-plane with the corresponding matching of tapered ramp 110, and the top of the first plunger 410 is set
Have along the footpath convex of the first plunger 410 and rise to the bait 411, the bottom of the first plunger 410 is provided with outside along the footpath of the first plunger 410
