Description

A kind of aluminum alloy profile of chassis base

technical field

The invention belongs to the field of electrical and communication equipment casings, relates to a frame-structured assembled casing, in particular to an aluminum alloy profile of a casing base.

Background technique

At present, the most widely used and the highest market share of the chassis and cabinet frame profiles on the market are the 16-fold and 10-fold profiles disclosed by the German Rittal Company in 1997. Rittal's subsidiary in China, Rittal Electromechanical Technology (Shanghai) Co., Ltd. issued the authorization announcement number CN 103987229 B, and the authorization announcement date was 2019.03.15. A profile for cabinet frame was disclosed; Donghua University's announcement number was CN 101963276 A, authorization announcement date 2011.02.02 discloses a twelve-fold profile with folds formed by cold pressing. The above two profiles are cold-rolled carbon steel sheet cold-formed profiles. The profile production process is generally as follows: the first step is to level the cold-rolled carbon steel plate coil; the second step, the continuous stamping die punches out the standard spacing Module mounting holes; the third step, the cold bending equipment is gradually formed by cold bending; the fourth step, cut to a certain length; the fifth step, cut to the required length according to the needs; Phosphorus washing, drying, plug hole protection, electrostatic spraying, curing and drying. The advantage of this type of profile is that there are mounting holes on the top of the profile, and the profiles can be connected by screwing, riveting, etc. to assemble the cabinet frame, or the door panels, side panels and other related accessories outside the cabinet can be fixed and installed through the mounting holes on the profile. 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 The area is relatively large, the weight per unit length is relatively heavy, and the assembled case is relatively bulky.

According to the retrieval, most of the profiles on the market are adjusted and improved on the basis of the profiles of the German Rittal company, which are called imitation Rittal cabinet profiles in the market. A real profile with simple production process, simple assembly, light weight and high strength has not yet been found.
