Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a cutting device for processing an oblate tube. Background Art

[0002] The Type-C interface is an oblate round port, like a flattened rectangle. It is smaller than the USB2.0 interface on a computer, and flatter than the mini USB port on a mobile phone, but slightly longer. Type-C does not distinguish between the front and back sides, and its transmission rate is also faster, and the data transmission speed is also faster. It also supports video output. It can be said that it is a line that integrates multiple functions such as data transmission, charging, and video stream output. Therefore, in the production process of Type-C, it is particularly important to design a cutting device for processing oblate round tubes.

[0003] During the cutting process of the existing device, it is difficult to avoid cutting stress due to the hollow structure of the flat round tube. There is a certain amount of deformation on the edge of the Type-C metal part after cutting, which means quality defects exist for high-precision requirements. Utility Model Content

[0033] The device is further configured such that the top of the knife seat 8 is a conical structure.

[0034] The solution makes it easier for the flat round tube to be put on the knife holder, thus preventing the cross section of the flat round tube from getting stuck with the top of the knife holder, which would affect cutting.
