Description

  The present invention relates to furniture and a method for manufacturing furniture designed to contribute to a reduction in manufacturing cost.

Conventionally, when making a furniture casing as shown in Patent Document 1 with a metal plate, a reinforcing member is spotted on a required portion requiring reinforcement among the face plate portions constituting the back plate, the left and right side plates, the top plate, and the bottom plate. Usually, it is attached by welding, and coating is applied from above.
JP 2005-124725 A

  However, in order to rely only on spot welding, it is necessary to increase the number of welded portions to some extent, so there is a problem that spot weld marks deteriorate the appearance quality of the product. This is unavoidable even if the paint is applied from above, but rather tends to stand out. In addition, spot welding is merely point bonding between the contact surfaces, and does not continuously reinforce the entire face plate portion. For this reason, there is a limit to reducing the thickness of the face plate portion in obtaining the required strength, and there is a limit to improving the strength and reducing the material cost in mass production. Basically, when relying on spot welding, the number of welds must be increased to some extent. However, when spot welding is performed manually, man-hours and skill are required, and as a result, the number of welds increases and production efficiency decreases significantly. Invite.

  The present invention has been made paying attention to such problems, and comprises a new structure and process capable of further reducing the thickness of the face plate portion of the housing and not impairing the production efficiency. It aims at providing furniture and a manufacturing method of furniture.

  In order to achieve this object, the present invention takes the following measures.

That is, the furniture according to the present invention includes a casing made of a plurality of metal face plate portions, and the reinforcing member that supplements the surface strength with respect to a required face plate portion of the case includes the face plate portion and the reinforcing member. Coating is performed by applying a powder coating on the surface and baking it, with a thermosetting adhesive that forms a gel at normal temperature over almost the entire area in at least a part of the contact surface. has been made, with the reinforcing member is provided so as to extend in the width direction of the front edge of the face plate portion constituting the top plate and a bottom plate connecting the side plates, the front edge of the faceplate portion constituting the left and right side plates and wherein the reinforcing member is provided so as to extend in the vertical direction, the by connecting the reinforcing member of the top plate and bottom plate and reinforcement member of the left and right side plates, frame-like structure around the opening It is characterized by comprising.

In this way, if the reinforcing member is bonded to the surface of the contact surface between the face plate portion and the reinforcing member over almost the entire predetermined direction via the adhesive, the bonding itself does not affect the product surface. The appearance quality of the product can be effectively improved as compared with point bonding. Further, since the members can be bonded almost entirely, it is possible to effectively increase the strength of the entire face plate portion, or to effectively realize further thinning of the face plate portion of the housing without damaging the strength. Furthermore, since the adhesive is cured by heat using the heat generated when the powder coating is baked and hardened, it is possible to ensure a reliable adhesive action without increasing the number of steps.

In addition, the top plate and the bottom plate that connect the side plates have reinforcing members extending in the width direction on the front edge side of the face plate portion, and the reinforcing members provided on the front edge side of the top plate and the bottom plate and the left and right side plates; Are connected to each other to form a frame-like structure around the opening, which is more effective.

  In order to further enhance the reinforcing effect of the face plate portion by the reinforcing member, a bent portion is formed at the edge portion of the face plate portion, and a bent portion that fits inside the bent portion is also formed at the corresponding edge portion of the reinforcing member. It is preferable that the reinforcing member is attached to the face plate portion in a state in which the two bent portions are fitted together.

  In order to obtain a further effect by combining the reinforcement with the adhesive with the structure of the housing, it is also possible to adhere to almost the entire area along the direction perpendicular to the folding direction, to at least a part of the contact surface between the folded parts. It is desirable to intervene an agent.

In particular, in order to obtain a high reinforcing effect on the compressive strength acting on the housing, a back plate and a side plate mainly composed of a face plate portion are formed by bending a metal plate, and the top and bottom of the side plate are vertically moved. It is desirable that an extending reinforcing member is attached with the thermosetting adhesive interposed therebetween, and a bent portion formed on a part of the front reinforcing member is fitted to a bent portion formed on the front edge portion of the side plate.

In order to further improve the strength of the face plate portion by adding a slight configuration, in addition to the adhesive layer of the thermosetting adhesive, a point adhesive portion by welding or the like is provided at an intermittent position along a predetermined direction. Is preferred.

  And, in order to effectively reduce the manufacturing cost over a plurality of types of furniture, a mode in which a shelf is mounted with a reinforcing member as a rack mounting portion, a mode in which a door is mounted using a reinforcing member as a door mounting portion, or reinforcement It is preferable that a member can be used as a drawer attachment portion so that the drawer can be attached.

When a door is mounted using a reinforcing member as a door mounting portion, in order to effectively compensate for the door surface strength with a simple configuration, the reinforcement that supplements the surface strength of the metal face plate portion constituting the door A member is attached only by the thermosetting adhesive interposed between at least a part of the contact surface between the face plate portion and the reinforcing member over almost the entire region in a predetermined direction, or the thermosetting adhesive as a main component. It is easy to be.

  On the other hand, the present invention can constitute effective furniture that comprehensively considers the appearance, strength, and cost by the combination of the thermosetting adhesive and the point bonding.

  That is, the furniture according to the present invention is characterized in that a reinforcing material for at least the back surface of the face material constituting the exterior surface is attached by a thermosetting adhesive and a minimum point adhesion. This is because the appearance quality can be improved as much as possible. Here, the exterior surface of the furniture refers to a surface exposed to the outside of the furniture in the installed state.

  In this case, it is desirable that the reinforcing material for the back surface of the face material that does not constitute the exterior surface of the furniture is attached by point bonding. This is because if the appearance is not affected, the amount of adhesive used can be saved and the cost can be reduced.

In a similar vein, while the site each other do not constitute the appearance surface a assembled portion between the surface material and the face material also desirably is joined by a point bonding.

  And if a reinforcing material is attached to the back surface of the face material by an adhesive and a minimum point adhesion and the furniture constituent member is pre-configured, the handling is simple and the furniture can be assembled with good appearance quality.

  On the other hand, in the furniture manufacturing method according to the present invention, the reinforcing member that supplements the surface strength of the face plate portion that constitutes the furniture casing is provided on at least a part of the contact surface between the face plate portion and the reinforcing member in a predetermined direction. After applying a thermosetting adhesive over the entire area, the reinforcing member is temporarily fixed to the face plate by point bonding by welding or the like, and then the adhesive is cured by heat to bond the face plate portion and the reinforcing member. It is characterized by being bonded to the surface.

  In this way, the reinforcing member can be attached to the face plate portion with high strength by simply applying the adhesive and performing heat treatment after applying welding or the like to the minimum necessary portion. For this reason, it is possible to effectively give the necessary strength to the furniture casing composed of a thin face plate without increasing the number of steps.

  In order to eliminate the need for a separate process necessary for thermosetting, it is desirable to use the heat of the drying step after cleaning associated with the chemical conversion treatment.

  For the same purpose, it is also desirable to cure the adhesive by heat by using the heat at the time of baking after the coating is applied.

  Since the present invention has the configuration described above, the appearance quality of the product is reliably improved by reducing welding traces as much as possible, and the face plate portion of the housing can be thinned without losing the strength, or the housing itself. It is also possible to improve the strength of the furniture, and it is possible to provide a furniture and a method for manufacturing the furniture comprising a new and useful structure and process that can effectively improve the production efficiency.

And this bending part 36d is fitted in the bending part 35 of the top plate 3 mentioned above. That is, the relationship between the reinforcing member 36 and the top plate 3 is that the former mounting piece 36a and the latter face plate portion 31, the former front piece 36c1 and the latter front piece 35a, the former lower piece 36c2 and the latter horizontal piece 35b. Each surface is in contact with each other, and the former three surfaces are regulated from three sides by the latter.

  2 and 5, the bottom plate 3 has downward standing pieces 42 and 43 on the left and right and rear portions of the face plate portion 41, and further has a front bent portion 45 formed on the front edge portion. The front bent part 45 is a substantially L-shaped part composed of a front piece 45a that becomes the front surface (finding surface) of the bottom plate 4 and a horizontal piece 45b that gives the prospects necessary for fitting.

Surface contact is made, and the former three surfaces are regulated from the three sides by the latter.

  As shown in FIG. 2, reinforcing members 47 extending in the front-rear direction are attached to two locations separated in the width direction of the bottom plate 4 to reinforce the face plate portion 41. The reinforcing member 47 has a channel shape that opens upward, and the upper horizontal piece 47a is brought into surface contact with the lower surface of the face plate portion 41 of the bottom plate 4 so that an adjuster is attached to the bottom portion.

  The left and right side plates 2, back plate 1, top plate 3 and bottom plate 4 are assembled in a box shape shown in FIG. 1 by the following process.

  First, in constructing a back side plate composed of the side plate 2 and the back plate 1, preferably, reinforcing members 25 and 26 are attached to the face plate portion 21 of the side plate 2 in advance as shown in FIGS. 6 (a) → (b). 2, horizontal pieces 22, 23, 12, 13 are formed on the side plate 2 and the face plate portions 21 and 11 of the back plate 1 as shown in FIG. 2, and the bent portions 25d of the reinforcing member 25 are formed as shown in FIG. The bent portions 24 of the side plates 2 are fitted together while being molded. And the boundary part of the backplate 1 and the side plate 2 is made into the bending state shown in FIG. On the other hand, the top plate 3 and the bottom plate 4 shown in FIGS. 4 and 5 also preferably hold the standing pieces 45a and the horizontal pieces 45b with the standing pieces 46c1 and 46c2 after the reinforcing members 36 and 46 are attached to the face plate portions 31 and 41. To form. When the reinforcing members 25 and 26 are attached to the corresponding face plate portions 21, as shown in FIGS. 3 and 6A, the resin curable resin is hardened along substantially the entire longitudinal direction on the back surface of the attachment pieces 25b and 26a serving as contact surfaces. The adhesive S (shaded portion) is applied, and the reinforcing members 25 and 26 are attached to the face plate portion 31 through the adhesive S. Further, as shown in the illustrated example, the adhesive S is also applied to the surface of the front piece 25d3 of the front reinforcing member 25, and the bent portions 25d and 24 of the front reinforcing member 25 and the face plate portion 21 are fitted to each other. At this time, it is desirable that the adhesive S be interposed between the forward piece 25d3 and the front piece 24a. However, even if this part is not bonded with the adhesive S, it is sufficiently durable in terms of strength. The reinforcing member 36 and the face plate portion 31 of the top plate 3 shown in FIGS. 2 and 4 are also the same, between the former mounting piece 36b and the latter face plate portion 31, and between the former front piece 36c1 and the latter front piece 35a. An adhesive S is also interposed therebetween. In the illustrated example, the relationship between the reinforcing member 46 and the face plate portion 41 of the bottom plate 4 shown in FIGS. 2 and 5 is also between the former mounting piece 46b and the latter face plate portion 41, and between the former front piece 46c1 and the latter. Adhesive S is interposed between the front piece 45a, but this part is unlikely to affect the appearance quality unlike the top plate 3 and the side plate 2, so it is important to reduce the cost of the adhesive. You may rely only on adhesion. The same applies to the relationship between the reinforcing member 47 and the face plate portion 41 of the bottom plate 4.

  In this case, since the thermosetting adhesive S does not exhibit an adhesive function unless heat is applied, for example, in the reinforcing members 25 and 26 shown in FIG. Part P is provided. Such welding includes gas welding, arc welding, laser welding, and other point bonding means, including resistance welding called spot welding. The same applies to the other reinforcing members 36, 46 and 47.

  In the case of a normal case size, the above point bonding must be performed at 8 or more points. In this embodiment, the point bonding is performed so that the reinforcing member does not fall off or between the face material. Since it is only temporarily fixed so that no gap is generated, about three locations are sufficient. Of course, it is preferable that the point adhesion portion is slightly increased if the case is large.

  As an adhesive, considering the fact that galvanized steel sheets are often used for the plate material of this type of housing, it is possible to bond without degreasing. Is selected. Since acrylic and epoxy adhesives harden, it is preferable to use polybutadiene rubber or the like which is a sulfur curing agent. The temperature at which this type of adhesive functions is approximately 155 ° C. to 160 ° C., and it hardly acts even in a normal atmosphere, for example, about 100 ° C. For this reason, even if it exposes to air | atmosphere for a long time, a function is hardly impaired and it is maintenance-free with respect to an adhesive agent, such as not hardening | curing only by apply | coating like a two-component reaction agent.

  Then, the top plate 3 and the bottom plate 4 are attached to the side plate 2 and the back plate 1 as shown in FIG. The top plate 3 superposes the side edges of the side plate 2 and the back plate 1 on the lower surfaces of the upper pieces 22 and 12, and the bottom plate 4 superposes the standing pieces 42 and 43 on the side plates 2 and the back plate 1. In this case, as shown in FIG. 7, the front reinforcing member 25 of the left and right side plates 2 and the reinforcing members 36 and 46 of the top plate 3 and the bottom plate 4 are connected by the L-shaped connecting metal 5 in this embodiment, A frame-like structure part B is formed around the part. For connecting the top plate 3 and the bottom plate 4 to the side plate 2 and the back plate 1 and connecting the connecting metal fitting 5 to the reinforcing members 25, 36 and 46, an appropriate method can be adopted.

  And the chemical conversion process is performed with respect to the housing | casing A assembled as mentioned above. The chemical conversion treatment is for improving the coverage of the coating to be performed later and enhancing the rust prevention performance, etc., and comprises a step of applying necessary chemicals to the surface, washing, draining and drying (not shown). . The heat-curing adhesive S applied earlier reacts with the heat during the chemical conversion treatment. For example, in the relationship between the reinforcing member 25 and the side plate 2 shown in FIG. 8, the former forward piece 25d3 which is a contact surface. And the former front piece 24a, the former attachment piece 25b, and the latter face plate portion 21 are bonded together with the hardening of the adhesive material S as shown in FIG. The same applies to the relationship between the contact surfaces in other portions where the adhesive S is provided.

  And a coating process is given after said heat processing. In this coating process, the adhesive S is also cured by heat generated when the powder coating is applied and then baked. And since the temperature at the time of both heat treatment conditions satisfies the temperature condition for the thermosetting adhesive S to function, the adhesive S is almost completely cured by these, and the effect that the face materials are firmly bonded is expressed. To do. Thus, the furniture casing A shown in FIG. 1 is finally completed through the above steps.

  9 shows the open storage furniture 6 using the casing A, FIG. 10 shows the door-type storage furniture 7 using the casing A, and FIG. 11 shows the drawer using the casing A. This is a storage furniture 8 of the type. In the open storage furniture 6 shown in FIG. 9, the front reinforcing member 25 and the rear reinforcing member 26 are used as shelf mounting portions, and hook holes provided at a predetermined pitch on the rear surface of the front reinforcing member 25 and the inner surface of the rear reinforcing member 26. The shelf 62 can be hooked on the 25x and 26x via the shelf claw 61. Further, in the door-type storage furniture 7 shown in FIG. 10, the front reinforcing member 25 is used as a door mounting portion, and a trillion number 71 is attached to the trough number 71 so that the door 72 can be double-opened. The door 72 is made of metal mainly composed of the face plate portion 73, and a reinforcing member 74 extending in the vertical direction to reinforce the face plate portion 73 is bonded only to the back surface of the face plate portion 73 at the center in the width direction. It is attached. The reinforcing member 74 is provided with flange portions 74b on both sides of the channel-shaped protruding portion 74a. The flange portions 74b serve as contact surfaces with the face plate portion 5 and extend over almost the entire longitudinal direction (vertical direction). It is bonded via an adhesive. In the case of only bonding, it is of course possible to use a non-thermosetting adhesive, but in the case of using a thermosetting adhesive, it is a simple means until heat is applied as necessary. May be temporarily held by. Of course, as described above, a mounting structure and a mounting method comprising the thermosetting adhesive S and point bonding may be used, and it is rather preferable based on the gist of the present invention. Further, in the drawer-type storage furniture 8 shown in FIG. 11, the front reinforcing member 25 and the rear reinforcing member 26 are used as a drawer attaching portion, and a drawer 82 is attached to this via a rail 81.

As described above, the furniture according to this embodiment is applied by baking the powder coating applied to the surface, and the casing A composed of the plurality of metal face plate portions 11, 21, 31, 41 is provided. And reinforcing members 25, 26, 36, 46 that supplement the surface strength of the face plate portions 11, 21, 31, 41 of the housing A with the face plate portions 11, 21, 31, 41 and the reinforcing member 25. , 26, 36, 46 are attached to at least a part of the contact surface with a thermosetting adhesive S in the form of a gel at a normal temperature almost throughout the predetermined direction.

  If comprised in this way, since adhesion | attachment itself does not affect the product surface, the external appearance quality of a product can be improved effectively compared with the case where it relies only on point adhesion | attachment. Further, since the members can be bonded almost entirely, the strength of the face plate portions 25, 26, 36, 46 can be effectively increased as a whole. In other words, these face plate portions 25, 26, 36, and 46 themselves can contribute to further thinning, can surely reduce material costs in the case of mass production, and effectively reduce the weight of furniture. Can be realized.

  In this case, in this embodiment, the top plate 3 and the bottom plate 4 that connect the side plates 2 and 2 have reinforcing members 36 and 46 extending in the width direction on the front edge side of the face plate portions 31 and 41, and the top plate 3 and The reinforcing members 36 and 46 of the bottom plate 4 and the front reinforcing member 25 provided on the front edge side of the left and right side plates 2 are connected to form a frame-like structure B around the opening. Therefore, the top plate 3, the bottom plate 4 and the side plate 2 themselves are also reinforced by the reinforcing members 36, 46 and 25, and the top plate 3, the bottom plate 4 and the left and right side plates 2 are assembled. The frame-shaped structure portion B formed at the time of synthesizing can synergistically increase the strength of the periphery of the opening, and thus the entire casing A.

  In particular, the bent portions 24, 35, 45 are formed at the edge portions of the face plate portions 21, 31, 41, and the corresponding edge portions of the reinforcing members 25, 36, 46 are also fitted inside the bent portions 24, 35, 45. Folding portions 25d, 36d, 46d are formed, and the reinforcing members 24, 35, 45 are fitted to the face plate portions 21, 31, in a state in which both the bent portions 24, 25d, 35, 36d, 45, 46d are fitted together. 41, the bent portions 24, 35, 45 not only increase the surface strength of the face plate portions 21, 31, 41, but also fit the bent portions 25d, 36d, 46d of the reinforcing members 25, 36, 46 to this. Since the bent portions 24, 35, 45 of the face plate portions 21, 31, 41 are reinforced, the bonding strength between the face plate portions 21, 31, 41 and the reinforcing members 25, 36, 46 is increased. Reinforcing effect of the face plate portion 21, 31, 41 by the reinforcing member 25,36,46 is possible to effectively improve the body.

  More specifically, the adhesive covers almost the entire region along the direction orthogonal to the bending direction on at least a part of the contact surfaces of the bent portions 24, 25d, 35, 36d, 45, 46d. Since S is interposed, it is possible to further improve the strength of the bent portions 24, 35, 46, and consequently the strength of the face plate portions 21, 31, 41 provided with the bent portions 24, 35, 46.

  In particular, in the present embodiment, the back plate 1 and the side plate 2 mainly composed of the face plate portions 11 and 21 are formed by bending the metal plate, and the reinforcing members 25 and 36 extending vertically are bonded to the two front and rear portions of the side plate 2. An agent S is attached, and a bent portion 25 d formed on a part of the front reinforcing member 25 is fitted to a bent portion 24 formed on the front edge of the side plate 2. As described above, the back plate 1 and the side plate 2 serving as vertical surfaces that receive a vertical load are composed of a single metal plate, and in particular, a vertical surface on which a shelf load, a door load, a pull-out load, etc. act to easily apply a compressive load. Since the left and right side plates 2 are reinforced as described above, the strength of the casing A can be effectively increased. Of course, in the case of configuring a large casing, the back plate and the side plate are not separately configured and joined. In this case as well, since high rigidity can be imparted to each face material, the strength improvement necessary for the entire housing can be sufficiently expected.

  In addition, since the present embodiment is provided with a point adhesive portion P by welding or the like in addition to the adhesive layer by the adhesive S at intermittent positions along the predetermined direction, as compared with the case by the adhesive S alone, The strength of the face plate portions 21, 31, 41 can be further improved even by introducing only a few point bonding portions P.

  And in this embodiment, the aspect which attaches the shelf 62 using the reinforcement member 25 as a shelf attachment part, the aspect which attaches the door 72 using the reinforcement member 25 as a door attachment part, or the reinforcement member 25 as a drawer attachment part A mode in which the drawer 82 is attached by use can be selectively taken. Thus, depending on the function to be applied to the reinforcing member 25, it can be easily and diversely deployed from the common housing A to the open storage furniture 6, the door storage furniture 7, the drawer storage furniture 8, and the like. It is possible to significantly reduce the manufacturing cost over a plurality of types of furniture.

  In addition, when the door 72 is attached using the reinforcing member 25 as the door attachment portion, the reinforcement member 74 that supplements the surface strength of the metal face plate portion 73 constituting the door 72 is reinforced with the face plate portion 73. Since it is attached to at least a part of the contact surface with the member 74 only by the adhesive interposed over almost the entire region in the predetermined direction, the surface strength of the door 72 can be effectively ensured with a simple structure.

  On the other hand, the present embodiment realizes effective furniture that comprehensively considers the appearance, strength, and cost by the combination of the thermosetting adhesive S and point bonding.

  First, face members constituting at least the outer surface, for example, reinforcing members 36, 25, and 26 for the back surface of the top plate 3 and the side plate 2 are attached by a thermosetting adhesive S and a minimum point bonding portion P. Therefore, the appearance quality is improved by reducing welding marks as much as possible.

  The exterior surface of the furniture mentioned here is a surface exposed to the outside of the furniture in an installed state, that is, an outward surface, and the bottom surface of the bottom plate is not included because it is an inward surface. This is because it is difficult to see the eye and weld marks are difficult to see.

  And in the said embodiment, although the example which applied the adhesive agent S also to the face material which does not comprise the external appearance surface of furniture, for example, the reinforcing materials 46 and 47 with respect to the back surface of the baseplate 4, these are points from the said meaning. It is also effective to attach only by bonding, and the amount of adhesive used can be saved and the cost can be effectively reduced.

In a similar vein, a site that does not constitute the assembled part is a by appearance surface of the face material and the face material, such as adhesion to metal links 5 are desirably joined by point bonding.

  And, by attaching these reinforcing materials to the back of each face material in advance with an adhesive and a minimum point adhesion to constitute furniture components such as a back plate, handling becomes easy and appearance quality is good Can be assembled into simple furniture.

  On the other hand, the manufacturing method of furniture in the present embodiment includes reinforcing members 25, 26, 36, and 46 that supplement surface strength with respect to the face plate portions 21, 31, and 41 constituting the housing A of the furniture. A thermosetting adhesive S is applied to almost at least a part of the contact surface between 31 and 41 and the reinforcing members 25, 26, 36, and 46 in a predetermined direction, and the reinforcing members 25 and 26 are attached. , 36, 46 are temporarily fixed to the face plates 21, 31, 41 by point bonding by welding or the like, and then the adhesive S is cured by heat, and the face plate portions 21, 31, 41, and the reinforcing members 25, 26, 36, 46, The adhesive member S is simply applied, and the reinforcing member 25 is applied to the face plate portions 21, 31 and 41 by simply applying heat treatment after applying the adhesive S or the like to the minimum necessary portion. , 26, 36, 46 under high strength It can be attached. For this reason, it is possible to effectively give the necessary strength to the casing A including the thin face plate portions 21, 31, and 41 without increasing the number of steps. In particular, the thermosetting adhesive S does not start unless the required heat is applied with the intention to adhere, so even if it is left for a while after being applied, or even if the face material is in a twisted state, The member does not harden in the twisted state. For this reason, a highly accurate product can be manufactured without requiring cumbersome management or the like.

  In particular, the heat-curing of the adhesive S is carried out by utilizing the heat at the time of draining and drying during the chemical conversion treatment, so it is not necessary to provide a process necessary for the heat curing, effectively ensuring the production efficiency. can do.

  In addition, since the curing of the adhesive S by heat is performed by using the heat at the time of baking and solidifying the powder coating in the coating process, it is possible to ensure a reliable adhesive action without increasing the number of processes. it can. Finally, since the coating process is performed after the heat treatment, even if there is leakage of the adhesive from the adhesive surface, it is concealed to effectively improve the appearance of the casing A and thus the appearance of the furniture. It becomes possible.

  In addition, as an effect of the adhesive adopted above, because it is in the state of gel described, it may flow down even if the application surface is inclined by applying the face material after application to the required location. It is extremely convenient for handling because it is soft and easy to apply. Since this type of adhesive does not have the action of pulling the member, the face material and the reinforcing material are abutted with each other through the adhesive, and stress remains on the face material in a state of point bonding, so that there is a slight twist. Sometimes, if the stress is removed by the chemical conversion treatment or painting process, the face material is allowed to return to the state without twisting, and after that state, the adhesive is cured and the reinforcing material is bonded. to enable. Even if a slight gap remains between the members, since the adhesive has a certain thickness when applied, an effect as a filler for filling the gap can be expected.

  If the above steps are performed as much as possible by automation, the outline is that the step of applying an adhesive to the sheet metal, the step of placing the reinforcement on the point, the step of bending, the top plate and the bottom plate on the back plate Is a process of assembling using the alignment at the peripheral bent portion, a process of welding a required portion, a process of chemical conversion treatment, and a process of coating treatment.

  In the adhesive application process, the adhesive is sent by a pump and applied to a required location with a required length by numerical control. The adhesive S of the above type does not change at normal temperature. In other words, the soft gel-like state like toothpaste is kept almost constant, so it can be easily pumped and injected from the nozzle. Suitable for. As described above, the state of application thereafter is properly maintained.

  Welding to the reinforcing material is performed at a predetermined location by NC using a welding gun. If an inverter welder or the like is used, the current can be controlled, and the welding marks can be made as inconspicuous as possible.

  It is preferable to perform the chemical conversion treatment and the coating treatment while sequentially transporting the housing in a suspended state. Heat can be applied uniformly to the entire housing, and stress that causes twisting is less likely to act, so that surface accuracy can be expected to increase.

  The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, as shown in FIG. 12 as an example of the relationship between the face plate portion 21 of the side plate 2 and the front reinforcing member 25, a cavity x is provided between the reinforcing member 25 and the face plate portion 21, and leakage of the adhesive S from the contact surface. If there is a structure that escapes to the cavity x when there is, the protrusion of the adhesive S can be avoided, and the finished state can be kept good with a simple structure. In particular, a door that is easily visible when opened is effective.

  In the above embodiment, the present invention is applied to the side plate, the top plate, and the bottom plate. However, it is needless to say that the present invention may be applied only to a portion requiring reinforcement, for example, the side plate.

  Furthermore, when configuring a plurality of furniture by sharing a casing, it is not an essential requirement of the present invention that the form of the reinforcing member is slightly different, or even if the dimensions of the casing are slightly changed, Basic operational effects can be sufficiently achieved.

  Furthermore, for example, when attaching a trillion mounting bracket to a side plate, it is also effective to realize a complete welding-less by using a two-component curable adhesive, an acrylic honeymoon type adhesive, or the like. . Since this type of adhesive begins to solidify as soon as it is applied, a large reinforcing material or the like tends to have a problem of bonding when the face material is twisted. For parts, etc., twisting is not a problem, and it is not affected by the appearance quality if one with a small volume shrinkage is selected. It is also effective to complete.
