Description

A case based on aluminum alloy profile frame with foldable elbow bracket

technical field

The invention belongs to the field of electrical and communication equipment casings, and relates to a casing for temporary electricity and communication on a project site, in particular to a casing based on an aluminum alloy profile frame with a foldable elbow bracket.

Background technique

At present, the requirements for construction safety of engineering projects have been greatly improved, and the demand for temporary power distribution casings and temporary communication casings is increasing. However, at present, the temporary electric box on the market adopts the traditional sheet metal process, and generally does not use the skeleton profile as the frame. The production process is generally as follows: the first step is to use the cold-rolled carbon steel sheet with a certain length, width and thickness to unfold according to the bending. In the figure, use a large CNC punch or laser cutting to cut the material; the second step is to fold the bottom frame, door panel, mounting plate and mounting bracket of a box with precision bending equipment; the third step is to connect the bending gaps; The fourth step is to polish the solder joints; the fifth step is to clean, surface repair, polish, phosphor wash, dry, protect the plug holes, electrostatic spraying, curing and drying; Mounting brackets and other related accessories are assembled and formed. The advantage of this production process is that there is no profile skeleton, the holes for installing external components can be drilled when cutting materials, and the casing of any shape and size can be customized according to requirements. The disadvantages are: first, the lack of a skeleton leads to insufficient strength of the bottom frame, door panel, mounting plate and mounting bracket; second, large-scale production equipment is required, and the technical requirements in the production process are relatively high; third, each model The products are all customized products, which cannot achieve standardized production and do not meet the principle of large-scale mass production of industrial products; fourth, the mounting holes of external components are fixed, and flexible fixing cannot be achieved; fifth, the casing formed by this process, The weight is heavy, the cost is high, and the handling is inconvenient; sixth, once the casing formed by this process is damaged, it can only be replaced as a whole.

The authorization announcement number published by Rittal Electronic Machinery Technology (Shanghai) Co., Ltd. is CN 103974595 A, and the authorization announcement date is 2014.05.26. The cabinet frame is disclosed. The profile production process is generally as follows: the first step is to level the cold-rolled carbon steel plate coil material; the second step, the continuous stamping die punches out the modular mounting holes with standard spacing; the third step, the cold bending equipment is gradually cold-formed. ; fourth step, cut into a certain length; fifth step, cut into required lengths according to demand; sixth step, cleaning, surface repair, polishing, phosphorus washing, drying, protection plug hole, electrostatic spraying, curing and drying . The advantage of this type of profile is that there are installation holes on the profile, and the profiles can be connected by screwing, riveting, etc. to assemble into a cabinet frame. Mounted on the profile. The disadvantages are: first, the production process involves large-scale precision cold bending equipment, and a cold bending production line can only produce one type of profile, which requires at least twelve bending techniques and high precision in the production process; second, its The standard modular mounting holes are equally spaced, so that components and related accessories cannot be installed or fixed in the space between the standard modular mounting holes and the holes, and it is impossible to complete flexible assembly in the true sense; The plate and external related accessories still need to be punched to correspond to the standard modularized holes inside the profile. To make the two work well together, the difficulty factor of precision involved in the production process increases; fourth, the bending part of this cold-formed profile exists. The bending radius of the profile and the external door panel, side panel and external related accessories are screwed and riveted, which increases the difficulty factor to solve the problem of protection level; Fifth, the thickness and bending radius of the profile material lead to the profile section It has a large area and occupies a lot of internal space of the casing; sixth, the cabinet formed by this profile assembly is heavy, expensive, and inconvenient to handle; seventh, once the casing formed by this process is damaged, it can only be replaced as a whole. Lose.

According to the search, there is currently no frame-structured profile on the market that does not require secondary processing and is internally fixed to the assembled casing.
