Abstract

The utility model discloses a distribution box housing. The distribution box housing herein comprises a surrounding plate and a bottom plate, wherein the surrounding plate is formed by welding after the prefabricated entire plate being folded into a square, four bases of the wall side plate being respectively welded to the corresponding edges of the bottom plate, the four folding places of the wall side plate being shaped into circular smooth transition angles. The distribution box housing can be either housing for surface type or flush type box and has an inner slot which helps folding at the three folding places corresponding on the prefabricated entire plate. With little welding parts, the utility model can reduce adverse result caused by the unevenness of welding points. The utility model has the advantages of good structure rigidity, high materials utilization rate and high production efficiency, and energy saving and consumption reduction.

Description

The distribution box housing

Technical field

The utility model relates to a kind of process technology of outer case, refers to a kind of structure of distribution box housing especially.

Background technology

Process for the distribution box housing, how to improve the attractive in appearance of the utilance of sheet material, the rigidity of enhancing productivity, guarantee casing and appearance, be puzzlement insider's Several Key Problems, because exist the contradiction of many opposition between these several problems always.

For the processing of (not containing door and mounting panel part) of distribution box housing, at present, have two kinds of traditional mode of production forms in the industry:

First kind, the end and two limits (up and down or limit, the left and right sides) are materials all in one piece, be converted into the U type, the single blanking in both sides in addition, totally three plate assembly weldings form structure, need by predetermined scheme iron plate to be cut into three plates through plate shearing machine earlier, with bender descending material all in one piece plate partly is bent into the U type again, last and other two monolateral material assembly weldings form housing.

Second kind, iron plate is cut into the end and encloses side four limits totally five plates through plate shearing machine, assembly welding forms structure.As shown in Figure 3, Figure 4, wherein, shown in Fig. 3 is the structure of bright vanning, shown in Fig. 4 is the structure of concealed installation case, all can be found out by two figure: enclosing side four side plates all is veneers, need be when being integrated into the FCL body in the welding of place, four diagonal angles, the appearance that how much can directly have influence on the FCL body of welding experience.

More than two kinds of modes of production have following shortcoming:

1, cut out blanking with whole iron plate, the leftover bits and pieces of generation is more relatively, and stock utilization is lower;

2, need through shearing, bending, assembly welding, polishing four procedures, and solder joint is more, the position, corner needs polishing, modifies, and so production process is more, and production efficiency is difficult to improve;

3, the fastness of body structure is subjected to the influence of welding quality very big.

Summary of the invention

The purpose of this utility model provides a kind of province material and the good distribution box housing of performance.

For achieving the above object, the utility model is taked following design:

A kind of distribution box housing includes and encloses side plate and base plate; It encloses side plate and surrounds square back butt welding by a prefabricated whole plate bending and form, and weld with the base plate corresponding sides respectively on these four bases of enclosing side plate.

Four bending places of enclosing side plate are the rounding off angle.

Described distribution box housing is the housing of bright vanning or concealed installation case, has the inside groove that is beneficial to bending in three bending places of prefabricated whole plate correspondence.

The utility model has the advantages that:

1, the outward appearance vision is good, because of the welding position is few, can reduce the bad result that the injustice because of pad causes, and structural rigidity is very good.

2, stock utilization improves, and does not almost have leftover bits and pieces, and stock utilization is near 100%.

3, owing to reduced the workload of shearing, bending, welding and polishing, production efficiency significantly improves, and is energy-saving and cost-reducing.

Description of drawings

Fig. 1 is the utility model distribution box housing one embodiment (bright vanning) structural representation.

Fig. 2 is another embodiment of the utility model distribution box housing (concealed installation case) structural representation.

Fig. 3 is the bright vanning shell structure of a prior art schematic diagram.

Fig. 4 is a prior art concealed installation tank shell structural representation.

Below in conjunction with drawings and the specific embodiments the utility model is described in further details:

Embodiment

Consult Fig. 1, shown in Figure 3, the utility model distribution box (comprising bright vanning or concealed installation case) housing includes and encloses side plate 1 and base plate 2; Its improvement is: surround square back butt welding by a prefabricated whole plate bending and form, this prefabricated whole plate 1 bending surrounds the side plate that encloses that square back butt welding (at solder joint 3 places) forms the distribution box housing, and weld with base plate 2 corresponding sides respectively on these four bases of enclosing side plate.

Above-mentioned distribution box housing can adopt the quality steel plate blanking, and casing encloses side plate and is designed to a material all in one piece, adds a base plate material again, and totally two blocks of material are promptly finished structure, and stock utilization and working (machining) efficiency all can be largely increased.

Casing four limits are formed by a prefabricated whole plate bending, replace the method for several traditional plate amalgamation welding, make the outward appearance of casing, structural stability all be better than original structure.

Can be the rounding off angle in above-mentioned four bending places of enclosing side plate.

Described distribution box housing is the housing of bright vanning or concealed installation case, for the housing that makes making is beneficial to bending, has the inside groove that is beneficial to bending in three bending places of prefabricated whole plate correspondence.

Position, corner rounding off, smooth nature, can also change the R value at position, corner arbitrarily, can make the outward appearance of multiple style, because of the welding position few, can reduce the bad result that the injustice because of pad causes (as the polishing workload big and because polishing must influence outward appearance), not only make the outward appearance vision good, and structural rigidity be very good.

Owing to only determine two boards, stock utilization improves relatively, directly select the sheet material of suitable width specification for use, can accomplish does not almost have leftover bits and pieces, even select the higher relatively quality steel plate of price for use, because of the leftover bits and pieces pettiness, also can be not higher so make the cost of dividing, compare the raising that on performance and economic benefit, all can have by a relatively large margin than prior art.

The various embodiments described above can not break away under the scope of the present utility model in addition some variations, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit the protection range that the utility model is applied for a patent.
