Description
Technical Field
The invention belongs to the field of electrical and communication equipment, relates to an assembled shell with a frame structure, and particularly relates to an aluminum alloy section for a door leaf frame of the shell.
Background
The most widely used and most market-shared top-hat frame profiles are the sixteen-fold and nine-fold profiles disclosed in 1997 by Rittal, germany. An authorized bulletin number CN 103987229B published by Rittal corporation in Weichen electronic mechanical technology (Shanghai) Limited, a division of China, and an authorized bulletin date 2019.03.15 disclose a section bar for a cabinet frame; donghua university publication No. CN 101963276 a, granted bulletin date 2011.02.02 discloses a twelve-fold profile with cold-pressed pleats. The two types of section bars are formed by cold bending a cold rolled carbon steel plate, and the production process of the section bar generally comprises the following steps: firstly, leveling a cold rolled carbon steel plate coil stock; secondly, punching module mounting holes with standard intervals by using a continuous punching die; step three, gradually cold-bending and forming by cold-bending equipment; fourthly, cutting the steel plate into a certain length; fifthly, cutting the blank into required lengths according to requirements; and sixthly, cleaning, surface repairing, polishing, phosphorus washing, drying, protecting plug holes, electrostatic spraying, curing and drying. The section bar has the advantages that: mounting holes are formed in the sectional materials, the sectional materials can be connected in a screwing mode, a riveting mode and the like to assemble a cabinet frame, and related accessories outside the cabinet, such as door panels, side plates and the like, can be fixed and mounted on the sectional materials through the mounting holes in the sectional materials. The disadvantages are that: firstly, large-scale precise cold bending equipment is involved in the production process, one cold bending production line can only produce one section, and at least twelve bending steps are carried out, so that the requirements on the technology and the precision of the production process are high; secondly, the standard modular mounting holes are equidistant, so that elements and related accessories cannot be mounted or fixed in the space between the standard modular mounting holes and the holes, and the flexible assembly in the true sense cannot be completed; thirdly, the door plate, the side plate and the external related accessories of the door plate and the side plate are required to be punched to correspond to the standard modular hole site in the section bar, and the door plate, the side plate and the external related accessories are required to be matched well, so that the difficulty coefficient related to the precision in the production process is increased; fourthly, the bending radius of the bending part of the cold-bending section bar, and the bolt connection and riveting holes of the section bar, an external door panel, a side plate and external related accessories all increase the difficulty coefficient for solving the problem of protection grade; fifthly, the sectional area of the section is larger due to the thickness of the section material and the bending radius, the unit length weight is heavier, and the assembled and molded machine shell is heavier.
According to the search, most of the section bars on the market are adjusted and improved on the basis of the section bars of Rittal company in Germany, namely the imitation Wei picture cabinet on the market. A section with simple production process, simple assembly, light weight and high strength in the true sense is not found.
Disclosure of Invention
The invention aims to provide an aluminum alloy section for a door leaf frame of a machine shell, which overcomes the defects that a cold-formed section in the prior art is complex in production process, cannot be flexibly adjusted in installation position, high in production technology and precision requirements, large in sectional area, heavy after being assembled and formed and the like. The invention provides an aluminum alloy section for a door leaf frame of a machine shell, wherein an external sealing plate is fixed from the inside, all installation and fastening pieces are installed and fixed by utilizing a trapezoidal groove and a bridge cut-off opening in the section, and can be installed and fixed at any position in the length direction of the section.

The fold face be the stationary plane of outside perpendicular shrouding, with fold department filling structure sealed glue or install waterproof sealing strip additional in the assembling process, reach IP level sealed, have fine waterproof dustproof performance, and the casing of assembling by this kind of section bar uses under the circumstances that the environment is extremely poor, also can provide fine barrier propterty to installing in inside component of casing and equipment.
The baffle surface is a positioning surface of the external vertical sealing plate, the external sealing plate is blocked to be positioned on the section bar, and then the external sealing plate is supported on the corrugated surface from the inside of the section bar by using a fastener.
The first bridge cut-off opening is used for allowing a screw to penetrate through and connect the inner fastener and the outer fastener.
The second bridge cut-off mouth and T-slot be used for placing waterproof sealing strip, reach IP level sealed, have fine waterproof dustproof performance, and the casing of assembling by this kind of section bar uses under the circumstances that the environment is extremely poor, also can provide fine barrier propterty to installing in inside component of casing and equipment.
The trapezoidal groove is used for placing and hiding the fastener and can move at any position in the length direction of the trapezoidal groove, so that the aim of flexibly adjusting the fixed position is fulfilled.
The fold surface is provided with a plurality of barb folds with inward openings, so that the outer sealing plate and the waterproof sealing piece can be prevented from moving outwards, and the moving resistance of the outer sealing plate and the waterproof sealing piece is increased.
The cavity is arranged in the section bar so as to reduce the weight of the section bar in cross section and unit length.
Compared with the cold rolled carbon steel plate cold bending section bar in the prior art, the cold rolled carbon steel plate cold bending section bar has the following beneficial effects:
firstly, all the external sealing plates of the invention are not required to be punched, bent and welded, but are propped on the section bar from the inside by using related fasteners, and all the accessories and mounting fasteners are fixed on the trapezoidal grooves in the section bar of the invention.
