Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling apparatus for producing a strip having a cross section perpendicular to the longitudinal direction and having at least one projection. About. 2. Description of the Related Art The inventors of the present invention disclosed in Japanese Patent Application Laid-Open No. 4-327303 when rolling a deformed section material which is a rolled work 1 having at least one convex portion in the longitudinal direction, as shown in FIG. The rolling object 1 is brought into contact with the grooved rolling roll 2 by a guide roll 4 from a portion before the grooved rolling roll 2, or the material 1 is supplied to the portion from the tangential direction as shown in FIG. There is disclosed a method of accurately guiding the material to be rolled 1 to a rolling portion 8 of the grooved rolling roll 2 by rolling and contacting the grooved rolling roll 2 and rolling the material with high precision. Reference numeral 3 denotes a flat rolling roll which is in contact with the grooved rolling roll 2, 5 is a winding machine, 6 is an unwinding machine, 7
Indicates a guide roll. [0004] However, in the above-described method, the leading end of the material to be rolled 1 is fed from the unwinder 6 toward the guide roll 4 or 7 and charged into the rolling section 8. In carrying out the carrying-in work, the work 1 has to be charged while being appropriately bent, and the workability is extremely deteriorated. When the material 1 to be rolled is a soft material, when the material 1 to be rolled is brought into contact with the grooved rolling roll 2 by the guide rolls 4 and 7, the position of the convex portion of the material 1 is reduced. If the groove position of the rolling roll 2 greatly deviates, the convex portion is deformed, and the convex portion is pressed against the thin plate portion, thereby causing a two-plate defect. [0006] The present invention relates to the case where the material to be rolled 1 is soft,
Alternatively, even when the thickness difference between the convex portion and the thin plate portion of the material 1 to be rolled is small, the convex portion of the material 1 to be rolled can be accurately guided into the groove of the grooved rolling roll 2 and rolling can be performed. To provide a rolling device that is easy to perform. Means for Solving the Problems The inventors of the present invention have conducted intensive studies in order to solve the above-mentioned problems, and found that the material to be rolled 1 is placed on the grooved rolling roll 2 from a position before the rolling start position. The contact between the groove of the grooved rolling roll 2 and the convex portion of the material to be rolled 1 is performed so that the material to be rolled 1 is accurately guided to the grooved rolling roll 2 and rolled. The manufacturing apparatus improved so that the rolling process can be performed more accurately by the action of the grooved guide rolls 5 can be provided. [0008] That is, in the present invention, in a rolling apparatus for rolling a profiled cross section material having step portions having different thicknesses over the entire length in the longitudinal direction, an unwinding machine for feeding out the profiled cross section material, At the time of rolling, a pair of guide rolls and grooved guide rolls whose position fluctuates up and down, and has a groove-shaped step matching the step portion of the deformed cross-section strip, and the deformed cross-section strip is A pair of a grooved rolling roll and a flat rolling roll that rolls while allowing the stepped portion, and a winding machine that winds the irregularly shaped strip obtained via a pinch roll are provided. An embodiment of the present invention will be described below with reference to the drawings. In the present invention, as shown in the schematic diagram of the rolling device shown in FIG. 1, the unwinding machine 6 is provided with a deformed cross-section member having at least one convex portion whose cross section is perpendicular to the longitudinal direction in advance. The rolled product 1 is fed out between the guide roll 4 and the grooved guide roll 13 via the pinch roll 9, and the leading end thereof is wound up via the pinch roll 10 while being carried along the groove of the grooved roll 2. To be wound around the machine 5. In the rolling process, the guide roll 4 and the grooved guide roll 13 move upward as shown in FIG. Along the groove of the grooved rolling roll 2 and pressed to guide the rolled object 1 so as to contact the rolled material 1 longer than the bite length necessary for rolling. In this case, the convex portion of the work 1 is accurately fitted into the groove of the grooved roll 2 and the grooved roll 2
The rolling is performed in a rolling section 8 composed of a flat rolling roll 3 and the rolling section 8. By applying tension to the rolling target 1 from behind the rolling section 8, the contact between the rolling target 1 and the grooved rolling roll 2 is improved. You can be strong. However, it is not always necessary to apply tension in particular because the drawing tension by rolling also acts. Further, the tension in the rolling direction by the winding machine 5 is preferable in order to maintain the linearity of the rolled material 1 after rolling. The apparatus according to the present invention can accurately guide the rolled material 1 having the irregular cross section having at least one or more convex portions to the grooved rolling roll 2. Unlike the conventional method, a guide with accurate positioning is not required, and the rolling can be performed more accurately and more accurately than when a guide is used. Hereinafter, a specific example using the apparatus of the present invention will be described in detail. Specific Example 1 First, as shown in FIG.
A deformed cross-section material having one convex portion having a thickness of 0 mm, a convex portion width (W ′) of 10 mm, a plate thickness (T) of the convex portion 4 of 4 mm, and a plate thickness (t) of the concave portion 12 of 2 mm was prepared. Next, a grooved roll having a groove depth of 1 mm and a groove width of 10 mm (diameter 1
00 mm, overall width 100 mm) and a grooved roll (groove depth 0.5 mm, groove width 10 mm) (diameter 100 mm, overall width 10)
0 mm), and sequentially rolled at a rolling speed of 5 m / min, and then annealed in an oxygen-free atmosphere to obtain a total width (W) of 30 mm and a convex width (W).
') 10 mm, thickness of convex part (T) 1 mm, thickness of concave part (t)
A 0.5 mm pure copper annealed convex-shaped cross-section strip was obtained, and this was wound around the unwinding machine 6 as a rolled object 1. Next, the rolled material 1 is used as a final deformed cross-section strip, as shown in FIG.
') In order to perform rolling to a thickness of 10 mm, a thickness of the convex portion (T) of 0.6 mm, and a thickness of the concave portion (t) of 0.3 mm, as shown in FIG. Roller 2 with groove (diameter 100 mm, overall width 100 mm), flat roll 3 and guide roll 4 arranged in a horizontal position and guide roll 13 with groove (diameter 50 mm, overall width 100 mm)
After being fed between the grooved rolling roll 2 and the rolling roll 3 and passed through the pinch roll 10 to the winding machine 5,
The guide roll 4 and the grooved guide roll 13 are moved upward as shown in FIG. 2 to guide the convex portion of the work 1 to the groove of the grooved roll 2 prior to the rolling section 8, and the rolling speed 1
Rolling was carried out at 0 m / min to obtain the final deformed cross section material. Since the apparatus according to the present invention has the above-described structure, it can be used to roll a material to be rolled in the rolling of an irregularly shaped strip having at least one convex portion whose cross section is perpendicular to the longitudinal direction. 1
Is soft or the thickness difference between the convex portion and the concave portion of the work 1 is small, the convex portion of the work 1 is inserted into the groove of the grooved roll 2 by the action of the grooved guide roll 5. There is a great advantage that accurate guidance can be provided and that simple and high-precision rolling can be performed.
