Abstract

(57) [Problem] To provide a sink for a sink that can reduce the manufacturing cost by eliminating the joining work between a wire mesh and a metal plate, which has been required conventionally. SOLUTION: A rectangular metal sheet 22 is subjected to a punching process for forming a porous portion 23 and a punching process for obtaining a circular punched piece 24, and the obtained circular punched piece 24 with a porous portion 23 is drawn in a hat shape. It is formed by this. Bottom walls 2 and 12 with many holes, and peripheral wall with many holes at least in the lower half
3 and 13, and non-perforated flanges 4 and 14 on the upper edge of the peripheral walls 3 and 13.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to sinks for sinks (including wash basins), and more particularly to hat-shaped sinks for sinks obtained by a special manufacturing method.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a sink for a sink has been known which includes a bottom wall and a peripheral wall formed of a metal mesh, and a flange formed of a metal plate and joined to an upper edge portion of the peripheral wall.

[0003]

[Problems to be solved by the invention]

 In a conventional sink for a sink having the above-described configuration, there is a problem in that a joining operation between a metal mesh forming a bottom wall and a peripheral wall and a metal plate forming a flange is troublesome, and the manufacturing cost is high.

An object of the present invention is to provide a sink for a sink that can reduce the manufacturing cost by eliminating the joining work between a wire mesh and a metal plate, which has been conventionally required.

[0005]

[Means for Solving the Problems]

 The dust sink for sinks according to the present invention is a hatch-shaped circular punched piece with a perforated part obtained by performing a hole forming process to form a perforated part on a square metal sheet and a punching process to obtain a circular punched piece. This is a dust receiver formed by the above operation, and includes a bottom wall having a large number of holes, a peripheral wall having a large number of holes in at least a lower half, and a non-porous flange at the upper edge of the peripheral wall.

In order to manufacture the sink for the sink, a long metal thin plate wound in a coil shape is unwound, and the thin plate is cut at regular intervals in the length direction to form a square piece. You. Next, by performing a punching process and a punching process, a circular punched piece having a rectangular porous portion at the center and a non-porous portion at the periphery thereof is obtained. Next, the circular punched piece is subjected to drawing. As a result, a sink receiver for a sink including the bottom wall and the peripheral wall formed by the rectangular porous portion and the flange formed by the non-porous portion around the bottom wall is obtained. At this time, a non-porous portion will remain at the upper edge of the peripheral wall. However, by forming a rectangular porous portion so that a large number of holes are present in at least the lower half of the peripheral wall, a sink is formed. The function of receiving garbage is not impaired.

[0007]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a sink for a sink according to the invention. A sink for a sink (1) has a bottom wall (2) having a large number of holes and a large number of holes at least in a lower half. And a non-perforated flange (4) at the upper edge of the peripheral wall (3). The flange (4) has an angled cross section.

FIG. 2 shows another example of a sink receiver for a sink according to the present invention. The sink receiver for a sink (11) includes a bottom wall (12) having many holes and at least a lower half. It has a peripheral wall (13) having a large number of holes in its part, and a non-perforated flange (14) at the upper edge of the peripheral wall (3). The flange (14) is flat.

FIG. 3 shows a method of manufacturing a sink for a sink according to the present invention. The long metal sheet (21) wound in a coil shape is unwound, and first, the thin sheet (21) is cut at regular intervals in the length direction to form a square piece (22). Then, a circular punched piece (24) having a square porous portion (23) at the center and a non-porous portion (25) at the periphery thereof is obtained by performing punching and punching. Next, drawing is performed on the circular punched piece (24). As a result, the bottom wall (2) (12) and the peripheral wall (3) (13) formed from the rectangular porous portion (23) and the flange (4) ( The garbage trays (1) and (11) for the sink consisting of 14) are obtained. Drilling, punching, and drawing are all types of press working, and can be performed continuously using a required press machine. Note that the waste (26) after the circular portion is punched is discarded. After drawing, as shown in FIGS. 1 and 2, six arc-shaped non-porous portions (5) and (15) remain at the upper edge of the peripheral wall (3) (13). By forming the rectangular porous part (23) so that there are many holes in at least the lower half of (13), the function of the sink for dust sinks (1) and (11) is not impaired. .

In the dust sinks (1) and (11) for the sink shown in FIGS. 1 and 2, the bottom walls (2) and (12) are flat, but the bottom wall has a shape with a raised center. You can also.

[0012]

[Effect of the invention]

 According to the sink for the sink of the present invention, it is possible to manufacture only by press working such as drilling, punching and drawing, and the joining work between metal mesh and metal plate, which was required conventionally, is unnecessary. Therefore, the manufacturing cost can be reduced.
