Description

Cooling roll in a kind of fluid

The utility model relates to a kind of roll, cooling roll in particularly a kind of fluid.

At present, the mill roll mechanism of widespread usage in industrial machinery is the roller shell by cavity, and the roll shaft that embedding is enclosed in the lasso at roller shell two ends, be plugged in the lasso of two ends is respectively formed.This and roll structure are in the lumen closed state, and at work, its outer surface and both ends natural heat dissipation are very fast, but the high temperature that produces in the roller shell middle cavity is difficult to get rid of.Therefore often occurring the roll middle part in the practice is out of shape greatly, makes roll operation line speed be had a strong impact on and can't guarantee the rolling uniform disadvantage of embryo sheet thickness.

The utility model purpose is: overcome the prior art deficiency, but provide a kind of fluid media (medium) that utilizes that the roller shell inner chamber is cooled off to guarantee the roller temperature equilibrium, to make the roll long-term work and do not take place to cool off roll in the fluid of intermediate deformation.

The utility model is achieved in that cooling roll in a kind of fluid, comprise the cavity roller shell, be inlaid in the lasso at roller shell two ends and be inserted into the interior roll shaft of lasso, it is characterized in that: have the fluid media (medium) lead-in groove that runs through roll shaft vertically at the roll shaft center of roller shell one end, its inner port is joined with the blade drainage system inlet that is contained in the roller shell cavity, in the roller shell cavity of blade drainage system outlet side, be provided with the kuppe of external diameter less than the roller shell internal diameter, it joins by an external diameter and roller shell internal diameter, have the support set location of some even through holes on the periphery, have fluid media (medium) on the roller shell other end and derive groove.

Can in the roll operation process, constantly fluid be imported in the roll for the assurance fluid medium source, the swivel joint of introducing fluid media (medium) is housed on the roll shaft external end head that has fluid media (medium) lead-in groove end when realizing the utility model.

According to the difference of cooling fluid medium, when realizing the utility model, can have some even through holes near the periphery place at the lasso of the roller shell other end and derive groove as fluid media (medium).Or open a through hole vertically at the roll shaft center of the roller shell other end and derive groove as fluid media (medium), be connected to a swivel joint in the roll shaft outer end.

The utility model advantage is:

Adopt the blade vortex structure that fluid media (medium) is imported the roller shell inner chamber and to make it move ahead, flow out at last roll along the roller shell internal chamber wall external, so just, can effectively the inner heat that produces of roll in the work be taken out of and distribute, guarantee the roller temperature equilibrium, avoid the roll intermediate deformation that causes owing to overheated, thereby but guarantee rolling embryo sheet uniformity and the work of roll high-efficiency and continuous.

Below in conjunction with drawings and Examples the utility model is done further narration:

Overall work principle of the present utility model is: under the main frame working order, fluid cooling media is introduced the blade drainage system from an end roll shaft, eddy current effect by blade construction, medium just passes through the through hole of support set periphery, the outer wall of kuppe equably, flow through along the roller shell internal chamber wall, the temperature that the roller shell inner chamber is higher than medium is taken out of outside the roll body, thereby guarantees whole roller temperature equilibrium.

When implementing the utility model by above-mentioned principle, fluid media (medium) can select liquid (as cold oil) but, also gas (as air).

Embodiment 1 selects for use gas to make cooling medium, the roll structure as shown in Figure 1: form by swivel joint 1, roll shaft 2, lasso 3, roller shell 4, blade drainage system 5, support set 6, kuppe 7.The cold gas body source is joined by joint 1 and roll shaft 2, roll shaft 2 centers have gas lead-in groove 8 vertically, groove 8 causes blading 5 with gas, when rotating synchronously with roll, blading produces eddy current effect, so the gas of introducing is just blown away (referring to Fig. 2) by its blade forward along circumference equably, the place ahead is the support set 6 that is used for to unsettled kuppe 7 location.Support set 6 be one solid, certain thickness disk arranged, its external diameter periphery and the inwalls of roller shell 4 cavitys join, evenly have the dentation groove of some through holes 9 or gear on circumferential edge.The gas that is blown by blade moves ahead, passes then through hole 9 on the support set 6 again to the spaces that press from both sides of kuppe 7 outer walls and roller shell 4 inwalls along roller shell 4 inwalls.Kuppe 7 is cavity cylindrical structures, and its external diameter is less than roller shell 4 internal diameters, the long narrow fluid passage of the two formation one.Gas entered be able to behind this passage to roller shell 4 inwalls fully contact, heat-shift, walk to lasso 2 places of the roller shell other end then, this lasso upper edge circumferential edge has some through holes 10, gas is got rid of outside the roll body from these through holes 10 at last.From as can be known above-mentioned, after gas enters in the roller shell 4,, under through hole guiding, effect on blade, support set through hole, kuppe and the other end lasso, move ahead along roller shell 4 inwalls always, can realize interior cooling effect to greatest extent like this.

Embodiment 2 selects for use liquid as cooling medium, as shown in Figure 3: form by rotation liquid inlet joint 1, roll shaft 2, lasso 3, roller shell 4, blade drainage system 5, support set 6, kuppe 7, rotation fluid joint 12, this example is identical with embodiment 1 basic functional principle, structural difference is: because medium is a liquid, for guaranteeing that blading can make it evenly walk along roller shell 4 inwalls, so its blade density (referring to Fig. 4) greatly; For to the cooling liquid recycling,, also be provided with a swivel joint in addition and be convenient to normal withdrawal liquid in the main frame operation process so on the roll shaft of the other end, also have through hole 11 as the liquid lead-out groove.Support set 6 structures of Cai Yonging are gear-like (referring to Fig. 5) in this example, when cooling liquid moves ahead are to pass through from its those tooth grooves.
