As shown in the partially enlarged perspective view of FIG. 2, the convex portions 7 a and 7 b are formed such that the top portion 8 forms a substantially flat surface, and the convex portions 7 a and 7 b are curved upward in a longitudinal side view. It has a substantially flattened hemispherical shape (see FIG. 3C).

  A side surface 9 is formed from the top 8 toward the surface 6 of the stainless steel plate 5. The projections 7a and 7b have a substantially similar shape in plan view of the base (bottom) of the bottom and the plan view of the top 8, and the base (bottom) of the projections 7a and 7b from the top 8. It becomes a shape where the similar shape gradually expands until.

  Further, as shown in FIG. 2, a plurality of convex portions 7a and 7b are arranged at equal intervals, and six small convex portions 7b are arranged at equal distances around one large convex portion 7a. In addition, two small convex portions 7b are arranged between the large convex portions 7a in the direction from the large convex portion 7a to the small convex portion 7b. The plurality of convex portions 7a and 7b are formed by forming three virtual straight lines L between the arbitrary one convex portions 7a and 7b and the adjacent convex portions 7a and 7b at an angle θ of 60 degrees. It is arranged so that it can be drawn to intersect.

  As shown in the partially enlarged plan view of FIG. 2, the diameter (b) of the base (bottom) of the bottom of the large convex portion 7a is about 0.9 mm, and the diameter of the base (bottom) of the bottom of the small convex 7b is about 0.1 mm. The distance a from the center α of the large convex portion 7a to the center α ′ of the small convex portion 7b and the distance a between the centers α ′ of the small convex portions 7b are about 1.5 mm. It has become. Incidentally, the height g of the topmost surface 17 of the large convex portion 7a described later is about 0.03 mm, and the height g ′ of the topmost surface 17 of the small convex portion 7b is about 0.02 mm (FIG. 3). (See (c)).

  As shown in FIG. 3A, when embossing is performed on the stainless steel plate 5, it is performed by rolling using rolling rollers 10 and 11. On the outer peripheral surface 12 of one of the rolling rollers 10, a plurality of large concave portions 13a and small concave portions 13b having a substantially flat hemispherical inner space are formed. The stainless steel plate 5 used in the present example is a stainless steel plate 5 containing 0.5% by weight or more of Cu (copper) and depositing 0.2% by volume or more of a rich phase mainly composed of Cu. ing.

  The precipitation method of the rich phase mainly composed of Cu in the stainless steel plate 5 will be described in detail. The austenitic stainless steel containing 0.5% by weight or more of Cu is 500 to 900 ° C. after hot rolling until it becomes the final product. When the heat treatment is performed at least once in the temperature range, a rich phase mainly composed of Cu can be deposited on the stainless steel plate 5 by 0.2% by volume or more.

  As shown in FIG. 3B, when embossing the stainless steel plate 5, the rolling roller 10 in which the recesses 13a and 13b of the outer peripheral surface 12 are formed and the rolling roller 11 having a flat outer peripheral surface 12 ′ are formed. The stainless steel plate 5 is inserted therebetween, and rolling is performed while pressing the stainless steel plate 5 from above and below by these rolling rollers 10 and 11.

  When a part of the surface 6 of the stainless steel plate 5 is rolled by the rolling roller 10, it enters into the recesses 13 a and 13 b of the rolling roller 10, and at a position corresponding to the large recess 13 a of the surface 6 of the stainless steel plate 5, The large convex portion 7a is formed, the small convex portion 7b is formed at a position corresponding to the small concave portion 13b, and the pressing force of the rolling rollers 10 and 11 is appropriately adjusted. The top portions 8 of the convex portions 7a and 7b that have entered the inner space 13b are not brought into contact with the inner surface 16 of the concave portions 13a and 13b. Therefore, the upper surface of the top 8 is formed to be a substantially flat surface in a state where it is slightly bulged upward.

  As shown in FIG.3 (c), the some convex part 7a, 7b formed in the stainless steel plate 5 with the rolling roller 10 is the top surface 17 which makes a flat surface in the maximum height g and g 'site | part. (Topmost part) is formed. When the heights g and g ′ of the topmost surface 17 of each of the convex portions 7a and 7b are 100%, a portion of the convex portions 7a and 7b having a height h and h ′ of 80% or more is the top portion 8. It is composed.

  In the embossed forming method using the rolling rollers 10 and 11 according to the present embodiment, the depth of the concave portions 13a and 13b is set to a sufficient depth so that the convex portions 7a and 7b do not contact the back surface 16, and the diameter of the concave portions 13a and 13b. The maximum heights g and g ′ of the convex portions 7a and 7b can be determined by appropriately adjusting the size of and the pressing force of the rolling rollers 10 and 11. The convex portions 7a and 7b are pressed by the rolling rollers 10 and 11 at a time, so that the convex portions 7a and 7b are higher as the diameters of the concave portions 13a and 13b are larger, and the diameters of the concave portions 13a and 13b are smaller. It is designed to be so low.

  Further, the topmost surface 17 (topmost portion) may be formed by being brought into contact with the back surface 16 of the recesses 13a and 13b when pressed by the rolling rollers 10 and 11; The surface 17 becomes a slightly curved surface. In such a case, the maximum width of the plane widths m and m ′ of the topmost surface 17 referred to in the present embodiment is 95% or more of the protrusions 7a and 7b with respect to the highest portions g and g ′. It is defined as the parts 7a and 7b. Since this topmost surface 17 can reduce surface pressure compared with point contact when contacting parts such as cooking utensils are brought into contact with the convex portions 7a and 7b, the wear resistance of the convex portions 7a and 7b can be reduced. Can be improved.

  Further, the convex portions 7a and 7b are such that the planar widths i and i 'of the portions having heights h and h' of 80% with respect to the heights g and g 'of the top surface 17 are the bottom portions of the convex portions 7a and 7b. It is formed so as to be 50% or more and less than 100% of the plane widths k and k ′ of the base portion (bottom surface). Furthermore, the plane widths m and m ′ at least 95% of the height g of the topmost surface 17 are 10 times the plane widths k and k ′ of the base portions (bottom surfaces) of the bottoms of the convex portions 7a and 7b. % Or more dimensions. Thus, by specifying the shape of the convex portions 7a and 7b, the top 8 of the convex portions 7a and 7b becomes a flat shape.

  The plane widths i and i ′ can be adjusted by inclining the side surfaces of the recesses 13a and 13b, and in this embodiment, the recesses 13a and 13b whose surfaces contacting the side surface portion 9 are vertical are used. The convex portions 7a and 7b can be formed to have the gently rising side surface portions 9 by using the concave portions 13a and 13b whose surfaces contacting the side surface portions 9 are inclined or curved. If it does in this way, the cleaning property of the standup | rising part of convex part 7a, 7b can be improved.

  In this embodiment, since the shape of the projections 7a and 7b in a plan view is circular, for example, the plane widths k and k ′ of the bases (bottom surfaces) of the bottoms of the projections 7a and 7b and the projections 7a and 7b The diameter of the base (bottom surface) of the bottom of 7b is the same. In addition, when the shape of the projection in plan view is a shape other than a circle, the distance between the peripheral points of the base (bottom) of the bottom of the projection is connected by a straight line passing through the center of the projection. Of these, the longest distance is defined as the plane width k, k ′.

  As shown in FIG. 4A, after embossing the stainless steel plate 5 with the rolling rollers 10 and 11, the surface 6 including the convex portions 7a and 7b in the stainless steel plate 5 has a coating film having abrasion resistance. 18 is formed. The coating film 18 will be described in detail. The coating material used to form the coating film 18 includes various inorganic coating materials such as silica, titania, alumina, and zirconia, epoxy resin, acrylic resin, polyester resin, and urethane. Various organic paints such as resins, fluororesins, and silicone resins can be used.

  Various inorganic / organic composite paints such as silica / acrylic resin and silica / acrylic silicone resin can also be used. Furthermore, a lubricant may be added for the purpose of improving the wear resistance of the coating film 18. As the lubricant, fluororesin powder represented by tetrafluoroethylene, olefin resin powder such as polyethylene and polypropylene, polyethylene-fluororesin composite powder, silicone resin powder and the like are used.

  The method of forming the coating film 18 will be described by taking two examples of the forming method: an organic fluororesin paint and an inorganic / organic composite silica / acryl silicone resin paint.

  In the case of using a fluororesin paint, first, the stainless steel plate 5 is embossed, drawn according to the shape of the top plate 2 and sink 4 of the kitchen table 1, and then the stainless steel plate 5 is alkali degreased. . Then, a fluorine resin paint (solid content: 67% by weight of polyvinylidene fluoride resin, 28% by weight of acrylic resin, and 5% by weight of tetrafluoroethylene powder) is spray-coated so that the dry coating thickness is 5 μm. Thereafter, the stainless steel plate 5 is heated at 230 ° C. (predetermined temperature) for 15 minutes (predetermined time), whereby the paint is baked onto the stainless steel plate 5 to form the coating film 18.

  When a silica / acrylic silicone resin paint is used, first, the stainless steel plate 5 is embossed, drawn according to the shape of the top plate 2 and sink 4 of the kitchen table 1, and then the stainless steel plate 5 is subjected to alkali treatment. Degrease. Then, a paint obtained by adding 5% by weight of polyethylene resin powder in terms of solid content to silica / acrylic silicone resin (solid content: 24% by weight of colloidal silica, 43% by weight of silane hydrolysis condensate, 33% by weight of acrylic silicone resin) is used. Then, spray coating is performed so that the dry coating thickness is 5 μm. Thereafter, the stainless steel plate 5 is heated at 180 ° C. (predetermined temperature) for 20 minutes (predetermined time), whereby the paint is baked onto the stainless steel plate 5 to form the coating film 18.

  As described above, in the embossed stainless steel plate 5 in the present embodiment, the planar widths i and i ′ of the portions of the heights h and h ′ of 80% with respect to the heights g and g ′ of the top surface 17 are convex portions. The plane widths m and m ′ of the top surface 17 are 50% or more of the plane widths k and k ′ of the base portions (bottom surfaces) of the bottom portions 7a and 7b. By specifying the shape of the convex portions 7a and 7b to be less than 100% of the widths k and k ', the topmost surface 17 of the convex portions 7a and 7b becomes a flat shape, and the other on the stainless steel plate 5 When the cooking utensil 19 such as a pan used in the kitchen table 1 slides, the top surface 17 and the cooking utensil 19 are brought into surface contact with each other, and the contact pressure can be reduced. It becomes difficult for the wrinkles generated by the cooking utensil 19 to come into contact with the top surface 17.

  Further, the plurality of convex portions 7a and 7b are composed of at least two types of convex portions 7a and 7b, which are a large convex portion 7a and a small convex portion 7b having different heights g and g ′, respectively. The portions 7a and 7b are not evenly wrinkled, and the manner in which the respective convex portions 7a and 7b are attached and the timing of the wrinkles change, and the wrinkles attached to the plurality of convex portions 7a and 7b are not noticeable. Become.

  Further, since the small convex portions 7b are arranged so as to surround the large convex portions 7a, the small convex portions 7b are arranged between the plurality of large convex portions 7a. When the cooking utensil 19 comes into contact with the steel plate 5, the cooking utensil 19 comes into contact with the small convex portions 7b, so that the surface 6 of the stainless steel plate 5 between the large convex portions 7a is hardly wrinkled (FIG. 4). (See (a) and FIG. 4 (b)).

  More specifically, as shown in FIG. 4 (a), when the small convex portion 7b is disposed between the large convex portions 7a, when the cooking utensil 19 or the like is placed on the stainless steel plate 5, When the cooking utensil 19 or the like is slid on the stainless steel plate 5, the top portion 8 of the large convex portion 7a is higher than the top portion 8 of the small convex portion 7b, but the large convex portion 7a It becomes difficult for the top portion 8 of the small convex portion 7b disposed between the two to be wrinkled. Alternatively, even if the top 8 of the large convex portion 7a and the top 8 of the small convex portion 7b are simultaneously wrinkled, the directions of the wrinkles become different. Furthermore, since the space | interval of the top part 8 of the large convex part 7a which is easily wrinkled is wide, a wrinkle has become inconspicuous, and the beauty | look of the stainless steel plate 5 can be improved.

  Further, when the cooking utensil 19 or the like is inclined and slid on the stainless steel plate 5, the corners of the bottom surface of the cooking utensil 19 enter between the large convex portions 7a, and the stainless steel between the large convex portions 7a. Although there is a possibility of scuffing the surface 6 of the steel plate 5, in the embossing of the present embodiment, since the small convex portions 7b are arranged between the large convex portions 7a, the top 8 of the small convex portions 7b. The corners of the cooking utensil 19 are in contact with each other, and the corners of the cooking utensil 19 can be prevented from coming into contact with the surface 6, so that the surface 6 of the stainless steel plate 5 is not wrinkled.

  Furthermore, as shown in FIG. 4 (b), the convex portions 7a and 7b are worn by the use of the kitchen table 1 for many years. Since the coating film 18 having wear resistance is applied to the surfaces of the convex portions 7a and 7b, the wear of the convex portions 7a and 7b occurs when the coating film 18 is present on the surfaces of the convex portions 7a and 7b. Has been delayed. In this embodiment, since the large convex portion 7a and the small convex portion 7b are composed of at least two types of convex portions 7a and 7b, the coating film 18 of the large convex portion 7a is worn and the stainless steel metal part. Since the coating film 18 remains on the small convex portion 7b even when the large convex portion 7a wears out due to exposure, the small convex portion is formed by the coating film 18 on the small convex portion 7b. Wear of the portion 7b is delayed. Therefore, it is possible to provide the stainless steel plate 5 having wear resistance over a long period of time.

  Further, the top surface 17 is formed on a flat surface so that the planar widths m and m ′ of the top surface 17 are 10% or more of the planar widths k and k ′ of the bases (bottom surfaces) of the bottoms of the convex portions 7a and 7b. As a result, the top surface 17 does not need to be brought into point contact with the cooking utensil 19. Since the top surface 17 is a flat surface and the top portion 8 is flat, when the top coating surface 17 and the top portion 8 are spray-coated, the top surface 17 and the top portion are formed. The paint stays on the top 8, and a thick coating 18 can be formed on the top surface 17 and the top 8 as compared with the case where the convex portion has a hemispherical shape.

  In addition, the plurality of convex portions 7a and 7b are formed by connecting three virtual straight lines L between the arbitrary one convex portion 7a and 7b and the adjacent convex portions 7a and 7b at an angle θ of 60 degrees. It is possible to wipe the surface 6 of the stainless steel plate 5 from three directions intersecting each other at an angle of 60 degrees, so that the user of the kitchen table 1 can wipe the stainless steel. The work of wiping off the dirt on the steel plate 5 can be easily performed.

  Moreover, the surface 6 of the stainless steel plate 5 including the convex portions 7a and 7b is protected by forming the coating film 18 having abrasion resistance on the surface 6 including the convex portions 7a and 7b in the stainless steel plate 5, and so on. It can be set as the stainless steel plate 5 which is hard to stick.

  Further, after coating the surface 6 of the stainless steel plate 5 including the convex portions 7a and 7b, the stainless steel plate 5 is heated at a predetermined temperature so that the paint is baked onto the surface 6 of the stainless steel plate 5 including the convex portions 7a and 7b. By forming the coating film 18, it is possible to form the coating film 18 that is difficult to peel off, and the stainless steel plate 5 can withstand long-term use.

  Further, Cu (copper) is a relatively inexpensive element and is also effective as an antibacterial component, and the stainless steel plate 5 of this example contains 0.5% by weight or more of Cu, and the rich phase mainly composed of Cu. By precipitating 0.2% by volume or more, the stainless steel plate 5 having antibacterial properties can be formed. In addition, even if the convex portions 7a and 7b of the stainless steel plate 5 are worn, a rich phase mainly composed of Cu always appears from the inside of the stainless steel plate 5, so that the antibacterial property of the stainless steel plate 5 can be maintained.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the said Example, the stainless steel plate 5 to which the embossing which specified the shape of each convex part 7a, 7b was given is the upper surface of the top plate 2 of the kitchen stand 1, the upper surface of the gas stove 3, and the sink 4 However, the present invention is not limited to this, and the embossing of the present embodiment is applied to interior materials and exterior materials, furniture and electrical equipment used as building materials.
