Problems solved by technology

[0002] The mobile phone shell needs to process arc-shaped grooves, and the groove surface of the arc-shaped grooves is required to be very smooth. We usually use ball cutters to process them before. Ball cutter milling is not only slow, but also the smoothness of the processed grooves cannot meet the requirements. Therefore, we design A scraper was developed to meet the new requirements

Embodiment Construction

[0013] refer to figure 1 , figure 2 , the invention discloses a radial scraper, including a cutter head 1 and a cutter bar 2, the cutter head 1 includes a scraping edge surface 3, a rake surface 4 and a flank surface, and the flank surface and the scraping edge surface 3 Both are arc-shaped surfaces, the scraping edge surface 3 intersects with the rake face 4 to form the first cutting edge 5; the scraping edge surface 3 intersects with the flank surface to form the second cutting edge 6, so that the first cutting edge 5 and The second cutting edge 6 is arc-shaped, so that the arc-shaped groove can be scraped out. The knife bar 2 is provided with a transition surface 7, which can play the function of chip removal through the transition surface 7, and can avoid The problem of stress concentration can avoid reducing the strength of the cutter head 1. The transition surface 7 is in contact with the rake face 4, and the distance between the first cutting edge 5 and the apex of th...

Abstract

The invention discloses a radial scraper. The radial scraper comprises a tool bit and a cutter bar. The radial scraper is characterized in that the tool bit comprises a scraping edge surface, a fronttool face and a back tool face; the front tool face and the back tool face are arc-shaped faces, and the scraping edge surface and the front tool face form a first cutting edge, the scraping edge surface and the back tool face form a second cutting edge, a transitional face is arranged on the cutter bar, the transitional face is connected to the front tool face, and the distance from the first cutting edge to the peak of the tool bit is greater than that from the second cutting edge to the peak of the tool bit.

Description

technical field [0001] The invention relates to a cutter, especially a radial scraper. Background technique [0002] The mobile phone shell needs to process arc-shaped grooves, and the groove surface of the arc-shaped grooves is required to be very smooth. We usually use ball cutters to process them before. Ball cutter milling is not only slow, but also the smoothness of the processed grooves cannot meet the requirements. Therefore, we design A scraper was developed to meet the new requirements. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the invention provides a radial scraper. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A radial scraper, including a cutter head and a cutter bar, is characterized in that: the cutter head includes a scraping edge surface, a rake surface and a flank surface, and the flank surface and the scraping edge surface are arc-shaped sur...
