Detailed description of the invention
The present invention is described in detail below by the embodiment shown in below in conjunction with the accompanying drawings:
A kind of dismountable chill roll, it includes inner bag 10, is set in the roller 20 outside described inner bag 10, is separately positioned on first flange 30 and second flange 32 at inner bag 10 and roller 20 both ends, connecting on first flange 30 and have the first spindle nose assembly 50, the second flange 32 connects the second spindle nose assembly 60.
Wherein, inner bag 10 uses double extra-strong seamless steel pipe, roller 20 employing to be the seamless steel pipes of thin-walled, strengthens overall rigidity, can reduce the deflection deformation amount of roller 20 simultaneously.On the outer surface of inner bag 10, milling direct current muscle forms a plurality of runner 11 prolonging the extension of inner bag axis direction, for cooling WATER AS FLOW MEDIUM flowing, owing to runner 11 is straight line, is conducive to the impurity such as scale removal, makes roller 20 homogeneous temperature everywhere, and extend roller 20 life-span.Carry out again after roller 20 plating hard chromium on surface polishing and polishing, reach mirror effect, to improve the transparency and the planarization of film article.The roll surface of roller 20, by quenched and mid frequency induction hardening heat treatment, can improve the hardness of roll surface very well.
First spindle nose assembly 60 includes outlet pipe 52 and is arranged concentrically on the water inlet pipe 51 in this outlet pipe 52, described water inlet pipe 51 includes the first paragraph 51 ' being positioned at outlet pipe 52 and the second segment 51 between described the first flange 31 and the second flange 32 "; first paragraph 51 ' and second segment 51 " it is connected by adapter sleeve 40, second segment 51 " connect the first spindle nose assembly 50 and the second spindle nose assembly 60.Second spindle nose assembly 60, as the drive end of assembling motor, uses solid design, make chill roll rotate barycentre steadiness, flexibly, firm.
Offer the outlet pipe 52 described in multiple connection and the apopore 31 of runner 11 end on first flange 30, the second flange 32 offers the initiating terminal of multiple connection runner 11 and the inlet opening 33 of water inlet pipe 51.Specifically, the first flange 30 and the second flange 32 all use solid forging to strengthen intensity, each flange bores 10 uniform holes the most respectively, forms above-mentioned inlet opening 33 or apopore 31.
The Inlet and outlet water direction of the chill roll of the application is for holding Inlet and outlet water, three internal runners are one group, share an apopore and an inlet opening, cooling water flows into the inlet opening 33 on the right side of chill roll from water inlet pipe 51, then flow in runner 11 by multiple inlet openings, current right-to-left flows to the left end of chill roll, and flows into outlet pipe 52 from the apopore 31 of the first flange 30, flows out chill roll.
For ease of cleaning runner, remove the impurity being deposited in runner, it is detachably provided with the second annular end cap 35 of water inlet end for covering described runner 11 on the second described flange 32 and a side end face of roller 20, the first described flange 30 and the opposite side end face of roller 20 are detachably provided with the first annular end cap 34 of water side for covering described runner 11.Owing to runner 11 prolongs the axially extending of chill roll; first annular end cap 34 and the second annular end cap 35 are connected on roller 20 and the first flange 34 or the second flange 35 by fastening screw; after removing fastening screw; first annular end cap 34 and the second annular end cap 35 can be removed from chill roll; so that coming out in the two ends of runner 11; water under high pressure is utilized to wash by water in runner; the deposits such as the impurity in runner can be washed away; it is very easy to safeguard; and then the runner of protection chill roll is unobstructed; making chill roll rate of cooling everywhere consistent, cooling is uniformly.For ensure chill roll in the case of high-speed rotation the most eccentric, the fastening screw on roller 20 and the first flange 30 or the second flange 32 is interspersed, as shown in Figure 4 in a circumferential direction.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalence changes made according to present invention spirit or modification, all should contain within protection scope of the present invention.
