DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a polymer material, an inorganic material or a food material before firing,
The present invention relates to equipment for manufacturing plate-like materials having viscosity, such as metal materials, and a method for manufacturing plate-like materials using the equipment. In particular, the present invention relates to a plate material manufacturing equipment capable of changing the width of the plate material and a method of manufacturing the plate material using the equipment. (Prior art) The working roller pair of the plate material manufacturing equipment using the conventional roller pair has the rotating shaft of the working roller parallel. The roller pair has a barrel shape so as to eliminate the influence of the deflection of the roller in order to make the thickness of the plate-like material uniform in the width direction. Recently, a plate-like material manufacturing facility capable of tilting the working roller pair up to 1.5 ° has emerged, but the roller tilt angle is extremely small to some extent because the working roller pair has the same barrel shape as before.
In short, in the prior art, the equipment and manufacturing method for forming and processing a sheet material between a pair of rollers has been developed to use a barrel-shaped roller to uniformly manufacture the sheet material in the width direction.
It does not have the function of changing the width of the plate material or the function of displacing the plate material passage position, which is the object of the present invention. (Problems to be Solved by the Invention) It is a first object of the present invention to provide a plate-like material manufacturing facility capable of changing the width of the plate-like material. It is a second object of the present invention to provide a plate material manufacturing facility for expanding the width of the plate material. Further, a third object of the present invention is to provide a plate-like material manufacturing facility in which a load on a fluid outflow prevention side weir is small when solidifying and forming a fluid to produce a plate-like material. It is a fifth object of the present invention to provide a method for manufacturing a plate-like material that displaces the passing position of the plate-like material. (Means for Solving the Problems) The present invention is configured as follows. 1) According to the present invention, a working passage is formed by inclining a rotating shaft of a working roller in the direction of the passage center axis while maintaining axial symmetry of a pair of driven operation rollers of the same size with a drum-shaped or horn-shaped shape. This is a plate-like material manufacturing facility characterized by the following. FIGS. 1 to 8 are explanatory views of the constitutional example of the present invention. The thick line in FIGS. 1 and 5 is seen when the working roller 1 'in front of the plate material 6 is removed. Lines and thin lines indicate hidden lines or imaginary lines of the working roller 1 ′ before the plate-like material 6. In the present invention, when the plate-like material passage formed by the pair of operating rollers 1, 1 'is substantially constant in the width direction of the plate-like material, the longitudinal direction of the passage center shaft 2 is reduced to the extent that the roller pair becomes in the shape of a drum or a trumpet. And the working roller rotating shafts 3 and 3 'are mutually axially symmetrical with respect to the passage center axis 2 to form a machining passage.
In the present invention, the term "drum-shaped or horn-shaped" refers to a drum-shaped operation part of a working roller whose surface is symmetrical in the longitudinal direction of the working roller with a concave central portion, and is gradually cut off from one end thereof. It means to include the so-called trumpet shape whose diameter changes monotonically from to the other end. Also, "the operating roller rotating shaft is inclined in the direction of the central axis of the passage while maintaining axial symmetry with respect to the central axis of the passage" means that the operating roller completely overlaps when rotated 180 ° about the central axis of the passage, and Rotating shaft 3,
3 'are not parallel to each other, in other words, the shape and dimensions of the working roller pair 1, 1' are congruent. In other words, the rotating shafts 3, 3 'are inclined at equal angles A in the front-rear direction from the axis 4 orthogonal to the central axis of the passage. If the equipment of the present invention is configured so that the inclination angle A of the working roller rotating shaft 3.3 'can be selected, the width of the plate-like material can be changed according to the inclination angle. By configuring the present invention as described above, it is possible to provide a plate-like material manufacturing facility in which the width of the plate-like material can be changed and a plate-like material manufacturing facility in which the width of the plate-like material can be increased. It is possible to provide a method of manufacturing a plate-like material that displaces the passing position of the plate-like material by using it. 2) According to the present invention, at a position where the velocity vector of the contact surface of the working roller pair with the plate-like material is opposed to the outside of the passage on the large diameter side,
The plate-shaped material manufacturing equipment according to the above item 1), characterized in that the small diameter side is directed toward the center of the passage. In other words, in order for the velocity vector of the contact surface of the working roller pair with the plate-like material to be directed outward on the large diameter side of the working roller pair and toward the center of the passage on the small diameter side of the working roller pair, When using a pair of shaped rollers, as shown in FIG. 1, the working roller rotating shafts 3, 3 'are inclined at an angle A, and are shifted from each other in the longitudinal direction of the working roller rotating shaft. , 1 'are configured so that the large diameter part and the small diameter part face each other.
That is, as shown in FIGS. 1 to 8, the diameters of the pair of working rollers 1, 1 'are equal on the central axis 2 of the passage, and the magnitude relation between the right and left sides is switched. In such a plate material manufacturing equipment, the width of the plate material is remarkably increased during the processing of the plate material. By configuring the present invention as described above, it is possible to provide a plate-like material manufacturing facility capable of expanding the width of the plate-like material, and further use this facility to displace the passing position of the plate-like material. It is possible to provide a manufacturing method for. 3) The present invention is characterized in that, at the exit side of the passage, a pressing roller pair for pressing the width end of the plate-like material to the large diameter side of the pair of drum-shaped or horn-shaped working rollers is disposed. This is a plate-like material manufacturing facility. That is, in FIGS. 1 to 8, the driving roller pair 1, 1 'having the same size as a drum-shaped or bugle-shaped driving roller rotating shaft while maintaining the axial symmetry with respect to the central axis 2 of the passage.
3, 3 'is inclined at an angle A in the direction of the center axis of the passage to form a machining passage, and at the exit side of the passage, the end of the width of the plate-like material is formed into a large diameter of a pair of working rollers 1,1' of a drum or trumpet shape. A pair of pressing rollers 5, 5 'to press each side are arranged. That is, in this case, when using the hourglass-shaped operating rollers 1 and 1 'symmetrical in the roller length direction, the operating roller rotating shafts 3 and 3' are mutually connected so that a difference occurs in the operating roller diameter at the opposing position. It is displaced from the center of the passage in the axial direction of the working roller. With the above configuration, the plate-shaped material 6 spreads greatly in the width direction at a so-called roller contact portion between the working roller pair 1 and 1 ',
Even after passing through the roller contact portion, the end of the plate-like material tries to move to the pressing position of the pressing roller according to the movement of the working roller surface, so that the width of the plate-like material is further enlarged. In order to further increase the sheet-like material widening effect, it is desirable that the pressure roller pair 5, 5 'is also driven and that the velocity vector of the pressure roller contact surface is outward in the passage. By configuring the present invention as described above, it is possible to provide a plate-like material manufacturing facility capable of expanding the width of the plate-like material, and further use this facility to displace the passing position of the plate-like material. It is possible to provide a manufacturing method for. 4) In the present invention, at the position where the velocity vector of the contact surface of the working roller pair with the plate-shaped material is opposed, the large diameter side is directed toward the center of the passage, and the small diameter side is directed toward the outside of the passage. The plate-shaped material manufacturing equipment according to the above item 1), wherein the plate-shaped material manufacturing equipment is characterized by being solidified. That is, the relationship between the attitude of the working rollers 1 and 1 'and the driving direction is reversed from the technique described in 2), and the width of the fluid 7 and the plate-like material 6 from the working rollers 1 and 1' is reduced. Apply force in the direction. As a result, the pressure and heat load applied to the side weir 8 for preventing the outflow of the fluid 7 and the overall load associated therewith are reduced, and the side weir 8 can be omitted in the case of a thin plate or a highly viscous material. The fluid outflow prevention side weir used in the present invention should not be a flat surface like the conventional side weir operation surface but a twisted operation surface in consideration of the effect of the inclination of the rotation shaft of the operation roller. By configuring the present invention as described above, it is possible to provide a plate-shaped material manufacturing facility that reduces the width of the plate-shaped material. It is possible to provide a plate material manufacturing equipment with a small load, and it is possible to provide a method of manufacturing a plate material in which the passing position of the plate material is displaced using this equipment. 5) The plate material manufacturing equipment according to the above items 1) to 4), wherein the large diameter side of the pair of working rollers has a larger coefficient of friction than the small diameter side of the pair of working rollers. . To make the friction coefficient different between the opposing rollers, apply lubricant to one of the working rollers 1, 1 'as a means to reduce the friction coefficient, or reduce the surface roughness of the working rollers 1, 1'. As a means to increase the coefficient of friction, knurling is engraved on one roller or the skin is roughened.
It is better to increase the surface roughness. By configuring the present invention as described above, it is possible to provide a plate-like material manufacturing facility capable of largely changing the width of the plate-like material. It is possible to provide a plate material manufacturing equipment with a small load on the plate, and it is also possible to provide a method of manufacturing a plate material in which the passing position of the plate material is displaced using this equipment. 6) The present invention provides a plate-shaped material manufacturing facility in which a pair of driven working rollers having the same dimensions are inclined with respect to the center axis of the passage and the rotating shaft of the operating roller is inclined in the direction of the center axis of the passage to form a machining passage. This is a method of manufacturing a plate-like material, which involves changing the drive speed ratio between a pair of working rollers and displacing the passage position of the plate-like material when manufacturing the plate-like material using the method. For example, when a plate-like material is manufactured using the plate-like material manufacturing equipment described in the above items 1) to 5), as shown in FIGS. 1 to 8, the working roller rotating shafts 3, 3 'are used. When the driving speed of one of the working rollers is increased due to the inclination, the speed vector of this working roller in the width direction of the plate-shaped material, that is, the sideways speed vector of the other working roller is opposite to this. As a result, the plate-shaped material 6 is displaced laterally in the direction in which the operating roller whose driving speed is increased is sent out. Therefore, for example, when the center of the plate-shaped material 6 deviates from the passage center axis 2, the drive speed ratio between the working roller pair 1 and 1 'may be changed as this adjustment or control means. The direction of this operation is, for example, in the case of FIG. 1 where the plate material 6 flows from top to bottom, and when the plate material 6 is deviated to the right in FIG. What is necessary is just to change the drive speed ratio between the working roller pair 1 and 1 'so as to be relatively large. FIGS. 1 and 5 show the velocity vectors 9 and 10 of the working roller, however, the lateral velocity vectors are sinA times these. Further, in the present invention, for example, when a plate-like material is manufactured using the plate-like material manufacturing equipment described in the above item 3), the driving speed ratio between the driven pressing rollers is changed to displace the passing position of the plate-like material. can do. That is, using the plate material manufacturing equipment described in item 3) of the present invention, the plate material 6 is pressed against the working roller pairs 1, 1 'by the pressing roller pairs 5, 5', and the working rollers 1, 1 'are pressed. ′ And the driving force of the pressing rollers 5, 5 ′ to move the plate-like material 6 in the direction of movement of the surface of the working roller. Similar effects can be obtained. By configuring the present invention as described above, it is possible to provide a plate-like material manufacturing facility that changes the width of the plate-like material, and further uses this facility to manufacture a plate-like material that displaces the passing position of the plate-like material. It is possible to provide a law. The technique described in the above 6) can be applied to the case where the inclination angle of the rotating shaft of the working roller is extremely small, such as 1.5 ° or less, like the conventional equipment, and can displace the passing position of the plate-like material. The method has a sufficient effect as a meandering correction method and meandering control method and is included in the present invention. (Effect of the Invention) According to the present invention, it is possible to provide a plate-like material manufacturing facility in which the width of the plate-like material can be changed. Further, the present invention can provide a plate-like material manufacturing facility for expanding the width of the plate-like material. Further, according to the present invention, when manufacturing a plate material by solidifying and forming a fluid, it is possible to provide a plate material manufacturing facility with a small load on a fluid outflow prevention side weir. Further, the present invention can provide a method of manufacturing a plate-like material that displaces the passage position of the plate-like material. Industrial variations and practical variations are included in the present invention as long as the ideas of the present invention are utilized and the effects of the present invention are obtained.
