Abstract

The utility model discloses a welding-free box crossbeam, which comprises a bottom surface, a front surface, a back surface, a left surface and a right surface, wherein the bottom surface and the front surface are formed through folding, the bottom surface and the back surface are formed through folding, the left surface and the bottom surface are formed through folding, and the right surface and the bottom surface are formed through folding. The welding-free box crossbeam is attractive in appearance and high in manufacturing efficiency.

Description

Exempt to weld the casing crossbeam

Technical field

The utility model relates to appliance field, is specifically related to a kind of casing crossbeam of exempting to weld.

Background technology

Casing crossbeam in the low-tension switch cabinet, as shown in Figure 1, be to form bottom surface 7 by an entire plate flanging, front 5, next 6, in order to make the casing crossbeam stable, prior art mainly uses extra plate sheet material to be welded between front 5 and the back 6, form left surface 1 and right flank 2, left surface 1 and right flank 2 are commonly called as plug, and the weld 4 of plug and front 5 and back 6 unavoidably can form solder joint, not only influences integral aesthetic property, and the welding finish after, also may both lose time because not prison welding causes plug to come off, influence operating efficiency again, all there are the problems referred to above in existing low-tension switch cabinet.

The utility model content

The purpose of this utility model provides a kind of casing crossbeam of exempting to weld, and can well solve not attractive in appearance that existing low-tension switch cabinet casing crossbeam exists, the problem that operating efficiency is not high.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind ofly exempt to weld the casing crossbeam, comprise bottom surface, front, back, left surface, right flank, wherein bottom surface and front obtain by flanging, and bottom surface and back obtain by flanging, and left surface and underrun flanging obtain, and right flank and underrun flanging obtain.

Bottom surface, front, back, left surface, right flank all have installing hole.

The utility model is a kind of exempt to weld casing crossbeam final molding after because the plug place do not have solder joint, good looking appearance, and not existing because the two ends plug comes off and doing over again of causing is effectively saved Production Time, increases work efficiency.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is a prior art mesolow switch cubicle casing beam structure schematic diagram;

Fig. 2 is a kind of structural representation of exempting to weld the casing crossbeam of the utility model embodiment;

Fig. 3 is a kind of structural representation of exempting to weld the local a of casing crossbeam among Fig. 2;

Among the figure:

1, left surface; 2, right flank; 3, casing crossbeam; 4, weld; 5, front; 6, back; 7, bottom surface.

Embodiment

Shown in Fig. 2-3, provide a kind of a kind of embodiment that exempts to weld the casing crossbeam of the present utility model, comprising: bottom surface 7, front 5, back 6, left surface 1, right flank 2, wherein, bottom surface 7 and front 5 obtain by flanging, bottom surface 7 and back 6 obtain by flanging, left surface 1 obtains with the underrun flanging, and right flank 2 and bottom surface 7 obtain by flanging, wherein, bottom surface 7, front 5, back 6, left surface 1, right flank 2 are provided with installing hole, are used for fixing equipment.

In order more clearly to embody thought of the present utility model, further specify below in conjunction with manufacture method of the present utility model.

At first, sheet material is processed into as shown in Figure 3, Fig. 3 is a kind of structural representation of exempting to weld the local a of casing crossbeam among Fig. 2, b zone and a zone symmetry among Fig. 2, with sheet material shown in Figure 3 along the dotted line flanging, obtain as shown in Figure 2 exempt to weld the casing crossbeam, wherein, left surface 1 and right flank 2 make the front 5 and the back 6 that obtain by flanging more stable, simultaneously, because left surface 1 and right flank 2 obtain by flanging, so do not need to adopt prior welding mode, avoid because of welding cause attractive in appearance inadequately, and, the problem that operating efficiency that may cause owing to the solder joint problem of coming off can not get guaranteeing.

Claims

1. exempt to weld the casing crossbeam for one kind, comprise bottom surface (7), front (5), back (6), left surface (1), right flank (2), wherein bottom surface (7) obtain by flanging with front (5), bottom surface (7) obtains by flanging with back (6), it is characterized in that, left surface (1) obtains by flanging with bottom surface (7), and right flank (2) obtains by flanging with bottom surface (7).

2. exempt to weld the casing crossbeam as claim 1, it is characterized in that, bottom surface (7), front (5), back (6), left surface (1), right flank (2) all have installing hole.
