Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
All other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs 1-4, coiler mandrel improves structure, including coiler mandrel and rubber after a kind of installation rubber bush
Sleeve 5, coiler mandrel include that main shaft 4, icicle sleeve 2, fanning strip 1 and closing wedge 2, icicle sleeve 2 are set on main shaft 4,
Fanning strip 1 is equipped with 3,1 equidistantly distributed of fanning strip on 2 surface of icicle sleeve, and fanning strip 1 can along main shaft 4 it is radial do it is swollen
Contracting movement, closing wedge 3 also are provided with three, and each closing wedge 3 is arranged between two neighboring fanning strip 1, and closing wedge 3 can also
Breathing campaign is done along 4 radial direction of main shaft, rubber bush 5 is set in 1 surface of fanning strip.
Wherein, coiler mandrel work circular diameter is set as 468mm, and undergauge diameter is set as 435mm, the stroke of icicle sleeve 2
It is set as 113mm.
Wherein, the one-sided thickness of rubber bush 5 is 20mm, and the length of rubber bush 5 is 113mm, and internal diameter is set as 435mm.
Wherein, closing wedge 3 and pyramid sleeve T-slot face angle degree, are greater than fanning strip 1 and pyramid sleeve T-slot face angle degree.
Wherein, it is mentioned when fanning strip 1 and closing wedge 3 do breathing campaign by dynamical system, the hydraulic system outside rotary machine
For driving force.
In order to make the fanning strip 1 of coiler mandrel become a complete circle, fanning strip 1 and sector in swollen extremely work bowlder
Gap is not present between plate 1.Only coiler mandrel structure is transformed, reel coiler mandrel is changed to 3 by 4 pieces of fanning strips
Block fanning strip is added three closing wedges 3 with the breathing simultaneously of fanning strip 1 between three pieces of fanning strips 1, fills up every piece with closing wedge 3
Fanning strip 1 is swollen to the gap for the bowlder that works.And reduces mandrel diameter of coiling machine, certain thickness rubber bush 5 in fixation, reach
It is identical as preceding size is transformed to the final working diameter of reel.Accomplish to be formed between band coil of strip inner hole and winding machine reel sector plate soft
When the coiler mandrel circular diameter to work swollen by undergauge state, closing wedge 3 must move to the work circular diameter of reel for contact,
With the gap filled up between fanning strip 1 and fanning strip 1.And be fitted close with two pieces of adjacent fanning strips 1, there cannot be gap.
When reel is reduced to undergauge state by work circular diameter, closing wedge 3 must move first, be reduced to undergauge state prior to fanning strip 1.
Otherwise fanning strip 1 in undergauge by 3 card resistance of abutting closure wedge, can not undergauge, so closing wedge 3 and pyramid sleeve T-slot face angle
Degree is greater than fanning strip and pyramid sleeve T-slot face angle degree, is formed when pyramid sleeve 2 is moved along 1 axial direction of main shaft, envelope
It closes wedge 3, the speed difference that fanning strip 1 radially moves, solves fanning strip 1 and asked in undergauge by 3 card resistance of abutting closure wedge
Topic.
Reel coiler mandrel work circular diameter 508mm is changed to 468mm, undergauge diameter is changed to 435mm by 475mm.Icicle
2 stroke 113mm of sleeve is constant.The one-sided thickness for adding rubber bush 5 is 20mm, internal diameter 435mm.It is suitable for convenience of rubber bush 5
Benefit installation, the second step undergauge for being less than 435mm is realized using three station rotary hydraulic cylinders, smooth in order to rubber bush 5
Dismounting reduces overhead time.Plus after rubber bush 5 on coiler mandrel, reel final diameter is still 508mm.Meet
Produce original product variety.Remaining each installation dimension does not change.As long as replacing the fanning strip 1 on coiler mandrel, pyramid set
Closing wedge 3 is added in the parts such as cylinder 5.
Under the conditions of reel takes motor-driven Force system, hydraulic system immovable, only change coiler mandrel structure and
The fixed upper rubber bush 5 of outside barrel diameter thoroughly solves coiler mandrel to band coil of strip with lesser equipment technology reconstruction expense
The impression problem of inner hole.
