Abstract
The utility model discloses a kind of rolling press, the axis being parallel of its top working roll and bottom working roll arranges and is in same plane, described bottom working roll is isodiametric round roller, top working roll is linearly contraction-like to both ends from middle part vertically, this top working roll is symmetrical arranged to the middle part of both ends contraction section relative to this top working roll from middle part, and top working roll both ends equal diameter and diameter in the middle part of top working roll are greater than the diameter at these top working roll both ends.This rolling press, when rolling, can effectively prevent because the temperature of supply channel both sides and the temperature at middle part exist a gradient difference, and is subject to the impact at supply channel direction of travel due to raw material, and in the middle part of the sheet material caused, thin both sides are thick, ensure that the planeness of sheet material.Thus, decrease the workload of follow-up leveling polished finish, also a saving starting material, reduce production cost.
Description
Technical field
The utility model belongs to calendering manufacture field, particularly a kind of rolling press.
Background technology
Existing devitrified glass, the steps such as its Production Flow Chart is batching, mixing, fusing, calendering formation, thermal cutting, thermal treatment, cold working, finished product.Usual devitrified glass need carry out Crystallizing treatment at crystallization rail kiln, and is rolled into sheet material by the rolling press at kilneye place.As shown in Figure 1, the top working roll 101 on existing rolling press and bottom working roll 102 are isodiametric round roller.Raw feed materials road rolling temperature controls between 1050 ° to 1100 °, material road width is 1.5m, because the temperature of supply channel both sides and the temperature at middle part exist a gradient difference during normal binder, and be subject to the impact at supply channel direction of travel due to raw material, in the middle part of the sheet material be pressed into, thin both sides are thick, cause the unfairness of plate face, sheet material must be determined by the plate face thickness of thickness thinnest part if will reach certain thickness, later stage also will carry out leveling polished finish to sheet material for this reason, both starting material are wasted like this, in turn increase later stage work amount, cause the increase of production cost.
Utility model content
Technical problem to be solved in the utility model is to provide after a kind of devitrified glass raw material is rolled guarantees the rolling press that plate is smooth.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of rolling press, comprise the top working roll and bottom working roll that are arranged side by side, the axis being parallel of described top working roll and described bottom working roll arranges and is in same plane, described bottom working roll is isodiametric round roller, described top working roll is linearly contraction-like to both ends from middle part vertically, this top working roll is symmetrical arranged to the middle part of both ends contraction section relative to this top working roll from middle part, and this top working roll both ends equal diameter and diameter in the middle part of described top working roll are greater than the diameter at these top working roll both ends.
Preferably, the length in the middle part of described top working roll is 1/4th of this top working roll total length.
Preferably, the 2mm ~ 5mm larger than the diameter at these top working roll both ends of the diameter in the middle part of described top working roll.
Preferably, the total length of described top working roll is 2000mm, and the length in the middle part of this top working roll is 500mm, the 3mm larger than the diameter at these top working roll both ends of the diameter in the middle part of described top working roll.
Preferably, described top working roll is the top working roll that high temperature material is made.
Preferably, described top working roll is the top working roll be made up of cast iron or forged steel.
A kind of rolling press provided by the utility model, the axis being parallel of its top working roll and bottom working roll arranges and is in same plane, bottom working roll is isodiametric round roller, top working roll is linearly contraction-like to both ends from middle part vertically, this top working roll is symmetrical arranged to the middle part of both ends contraction section relative to this top working roll from middle part, and top working roll both ends equal diameter and diameter in the middle part of top working roll are greater than the diameter at these top working roll both ends.This rolling press, when rolling, can effectively prevent because the temperature of supply channel both sides and the temperature at middle part exist a gradient difference, and is subject to the impact at supply channel direction of travel due to raw material, and in the middle part of the sheet material caused, thin both sides are thick, ensure that the planeness of sheet material.Thus, decrease the workload of follow-up leveling polished finish, also a saving starting material, reduce production cost.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 2, a kind of rolling press comprises the top working roll 1 and bottom working roll 2 that are arranged side by side, the axis being parallel of top working roll 1 and bottom working roll 2 arranges and is in same plane, bottom working roll 2 is isodiametric round roller, top working roll 1 is linearly contraction-like to both ends from middle part vertically, this top working roll 1 is symmetrical arranged to the middle part of both ends contraction section relative to this top working roll 1 from middle part, and this top working roll 1 both ends equal diameter and diameter in the middle part of top working roll 1 are greater than the diameter at these top working roll 1 both ends.This rolling press, when rolling, can effectively prevent because the temperature of supply channel both sides and the temperature at middle part exist a gradient difference, and is subject to the impact at supply channel direction of travel due to raw material, and in the middle part of the sheet material caused, thin both sides are thick, ensure that the planeness of sheet material.Thus, decrease the workload of follow-up leveling polished finish, also a saving starting material, reduce production cost.
According to the gradient difference of supply channel both sides temperature and middle portion temperature, preferably, the length in the middle part of top working roll 1 is 1/4th of this top working roll 1 total length.So, when rolling, the planeness of sheet material can be adjusted more accurately.
A kind of embodiment, as shown in Figure 3 and Figure 4, the total length of top working roll 1 is 2000mm, and the length in the middle part of this top working roll 1 is 500mm, the 2mm ~ 5mm larger than the diameter at these top working roll 1 both ends of the diameter in the middle part of top working roll 1, in the present embodiment preferred 3mm.So, the sheet metal thickness be pressed into is even, and plate face is smooth, and the qualified sheet material of every square meter can save 0.75 kilogram to 1 kilogram kilogram raw material (by density 2.5g/c ㎡, mean thickness is saved 0.3mm to 0.4mm and calculated).
Because raw feed materials road rolling temperature controls between 1050 ° to 1100 °, therefore, preferably, the top working roll that top working roll 1 is made for high temperature material, the preferred cast iron of this high temperature material or forged steel.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other embodiment easily according to guiding theory of the present utility model, and these embodiments are all included within scope of the present utility model.
