Nine-bend type section bar

Abstract

The invention discloses a nine-fold profile, which is characterized in that the cross-section of the nine-fold profile is an irregular closed figure formed by bending, and the second bending surface (1) is bent upward by 32 degrees to the right to form a second bending surface (1). Bending surface (2), the third bending surface (3) is formed by bending 58 degrees upward from the second bending surface (2), and the fourth bending surface (3) is formed by bending 90 degrees upward and rightward from the third bending surface (3). Bending surface (4), the fifth bending surface (5) is formed by bending 90 degrees upward from the fourth bending surface to the right, and the sixth bending surface (5) is formed by bending 90 degrees upward to the left from the first bending surface (1) 6), the seventh bending surface (7) is formed by bending the sixth bending surface (6) downward 90 degrees to the left, and the eighth bending surface ( 8), the ninth bending surface (9) is formed by bending the eighth bending surface (8) to the upper left by 90 degrees. This nine-fold profile has the advantages of small investment in production equipment and high structural strength.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a nine-fold profile. Background technique [0002] The cabinet frame is the core component of the cabinet load-bearing. The cabinet frame is usually processed by welding and other methods. Therefore, the structure of the profile determines the quality of the cabinet design to a large extent. At present, there are many types of cabinet profiles on the market, but generally speaking, most of them have the disadvantages of poor versatility, few installation positions and insufficient strength. At the same time, most of the existing cabinet profiles are processed by large-scale rolling equipment, which requires large equipment investment and poor adaptability, and cannot meet the market requirements of small batches and diversification of cabinet products. Therefore, how to optimize the profile structure and use the bending machine to bend and form the cabinet profile is an ef...
