A heat pipe groove forming knife and forming method for a 5G base station equipment shell

Abstract

The embodiment of the invention discloses a heat pipe groove forming knife for a 5G base station equipment housing, which includes an integrally formed knife handle and a cutting part; the knife handle and the cutting part have the same central axis; the cutting part includes a cutting edge and a cutting part. chip flute; the cutting edge includes a lower arc cutting edge, a straight cutting edge and an upper arc cutting edge connected sequentially from bottom to top; the handle includes a handle body and a connecting transition part, and the cutting part passes through The connecting transition part is connected with the handle body. The embodiment of the invention also discloses a heat pipe groove forming method for a 5G base station equipment casing. By adopting the invention, it can ensure that the cutting surface and the material keep in line contact during the rotation process of the forming knife, which is not easy to be worn, and the service life of the knife is improved. The connection between the tool holder body and the cutting part is strong, and it is not easy to break the knife; during milling, the cutting part can extend into the material to be processed through the transition part, which meets the forming process of heat pipe grooves of different depths, and has strong versatility.

Description

technical field [0001] The invention relates to the production field of 5G base station equipment shells, in particular to a heat pipe groove forming knife and a forming method for a 5G base station equipment shell. Background technique [0002] 5G base station equipment generates a lot of heat. It is often necessary to install heat pipe grooves on the housing, install heat pipes in the heat pipe grooves, and collect heat from around the housing through the heat pipes and transfer them to the radiator for heat dissipation. Through the above method, it can be ensured that the heat generated by the 5G base station equipment can be discharged in time to ensure the stability of its internal components. [0003] Since the heat pipe groove must be designed with its own specific shape so that the heat pipe can be fixed in the groove, the cross section of the heat pipe groove is mostly arc-shaped with an apex angle greater than 180 degrees. The existing heat pipe groove opening met...

AI Technical Summary

Problems solved by technology

The existing heat pipe groove opening method is to rough-mill the rough outline of the heat pipe groove first, and then fine-mill the predetermined cross-sectional shape. The fine-milling process requires the machining center to control the milling cutter to move up and down, left, and right in the heat pipe groove repeatedly, which requires multiple times. Milling forming, low efficiency

The cross-sectional shape of the heat pipe groove is determined by the shape and direction of the milling cutter. The heat pipe grooves processed by different manufacturers have different sizes, and the product quality is difficult to guarantee.

Heat pipe slots of different sizes and shapes are likely to cause cracks in the assembled copper pipes, affecting the heat dissipation effect of the equipment
