Description

  The present invention relates to an air outlet / inlet device having, for example, a wind direction adjusting function and a method for manufacturing the same.

  As a conventional air blowing suction port device, for example, a material of stainless steel and universal type is known. FIG. 14 and FIG. 15 show an example of a conventional air blowing inlet device. This is because the blades 4 are attached to the frame body 20 in parallel in either the vertical direction and the horizontal direction, or in any one of the vertical direction and the horizontal direction by the rotation shaft 4b, and each blade 4 is rotated to change the wind direction. It is configured.

  In this type of air blowout inlet device 40 made of stainless steel, blades are attached in various forms. For example, the construction method described in Patent Document 1 is known. In this method, the rotating shaft of the blade is inserted into the side plate portion of the frame body which is subjected to burring, and a load suitable for rotation is applied to the rotating shaft by the action of the spring back of the rotating shaft.

  In FIG. 14, the side plate C21 of the frame body to which the plurality of blades described above are rotatably attached and the side plate D22 of the frame body to which the blades are not attached are shown in a developed state. Needless to say, these four side plates have their ends cut at, for example, approximately 45 °, and these side plates must be joined by some method.

  As a joining method, conventionally, welding is generally performed by welding. That is, after the rising portion 20b and the frame portion 20a (see FIG. 15) of the side plate are attached together, they are welded and joined. Then, the welded frame portion is subjected to primary finishing with a disc grinder, then subjected to polishing by buffing as secondary finishing, and thereafter finishing such as polishing (BA) and hairline (HL). Finally, as a final finish, it was common to finish the welded portion that is not buffed by pickling (burning off).

Patent Document 2 describes a universal outlet device having a means for tilting a blade at a predetermined angle.

And a step of cutting off an end portion of the side plate, a side plate having the tenon produced by the step or a side plate having the tenon hole, or a side plate having the tenon produced by the step and the tenon hole. A step of attaching blades to both sides of the side plate, and a step of bending the side plate of the side plate having the tenon into the side hole of the side plate having the tenon hole and then bending the tenon. Manufacturing method of an air blowing inlet and wherein the door.

  By having the above configuration, the present invention can provide a low-cost air-blowing inlet device having a beautiful appearance and a method for manufacturing the same.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.

  The perspective view of the stainless steel air blowing inlet device 30 which concerns on a present Example is shown in FIG. The basic structure of the present apparatus is the same as that of the conventional air outlet / inlet apparatus shown in FIGS. 14 and 15, but the structure of the side plates of the frame body is different. That is, in the present invention, welding is not used, and the side plates are joined by caulking.

  In FIG. 1, a tenon portion 5 is provided at an end portion of one side plate A2, and a tenon hole portion 6 is provided at an end portion of the other side plate B3. FIG. 3 shows an enlarged view of the relief portion 5 and the relief hole portion 6. The joining and caulking of these tenon portions and tenon holes will be described in detail later.

  Next, the manufacturing process of the two types of side plates 2 and 3 constituting the frame of the air outlet / inlet device of the present invention will be described below. First, FIG. 4 shows the developed plate A of the side plate A having the ridge portion 5 at its end. In this figure, the position of the bending in the next process is also indicated by a one-dot chain line. A portion that becomes a tenon is formed at the position that becomes the end. What was bent in the bending position of FIG. 4 is shown in FIG. The bending at this time is performed by a press machine used for normal sheet metal bending.

  Further, the side plate A after being bent at the bending position of FIG. 5 is shown in FIG. Similarly, FIG. 7 shows the developed plate B of the side plate B, and FIG. 8 shows the result of the primary bending. In addition, the bending in FIG. 8 is performed at two places. This is because it is necessary to bend in two places, that is, the bending at the joint portion with the side plate A and the bending at the abutting portion 6b in the joint between the side plate A and the tenon 5a.

  Here, FIGS. 10 and 11 show enlarged views of the state of the bending portion 5 of the side plate A and the bending hole portion 6 of the side plate B before and after bending. As can be seen from FIGS. 10 and 11, in bending of the relief portion 5 and the relief hole portion 6, a part of the outermost portion (A in FIG. 10 and B in FIG. 11) is cut off simultaneously with the bending. This is because when the side plate A2 and the side plate B3 are butted to assemble the frame body, accurate and clean butting cannot be performed unless such corners are dropped. Further, such cutting-off is performed using a dedicated mold at the same time as bending of the above-described ridge portion and ridge hole portion. By doing so, it is possible to perform bending and cutting off with a single stroke of the press, and the mutual positional relationship between the bending part and the cutting off part is finished with very high accuracy.

  Further, the bending and cutting off of the ridge portion of the side plate A and the bending and cutting off of the ridge hole portion of the side plate B can be configured as one dedicated type. That is, the side plate A in the state shown in FIG. 5 and the side plate B in the state shown in FIG. 8 are mounted on one dedicated mold and brought into the state shown in FIGS. 6 and 9 with one press stroke. Is possible. With this type of configuration, the manufacturing cost can be further reduced.

  Next, FIG. 12 and FIG. 13 show a state in which the bending is finished and the side plate A and the side plate B to which the blades are attached are combined. FIG. 12 is a plan view, and FIG. 13 is a bottom view. As described above, excess meat is cut off at the extreme ends of both side plates, and bending processing is performed so that the rising dimension b of the horn and the falling dimension a of the horn hole shown in FIG. Therefore, when both side plates are assembled, the appearance is very clean.

  And the air blowing inlet device 30 which has a firm structure is completed only by bend | folding the tenon 5a finally inserted in the tenon hole 6a. The bottom view of FIG. 13 shows the bent state of the tenon. Note that a simple jig may be used in this side bending process.

  As described above, the frame of the stainless steel air blowing inlet device 30 according to the present invention is assembled by a simple method without using a joining method such as welding, so that the cost can be reduced, and bending and Because it uses a dedicated type that also cuts off, it becomes a frame that is very aesthetically pleasing. As a result, it is possible to provide an air blowing inlet device that is low in cost and excellent in appearance.
