Embodiment Construction

[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but the claimed protection scope is not limited to the description.

[0029] The idea of ​​manual sharpening drill mainly includes the following three points:

[0030] The first point: the design of the sharpening device, design the sample drawing of the drill sharpening device according to the diameter of the ordinary drill bit and the angle of the drill tip;

[0031] The second point: the manufacture of the sharpening device, on-site processing and manufacturing of the sharpening drill sample device according to the drawings of the sharpening tool.

[0032] The third point: practical application, use the sharpening device to sharpen the drill bit.

[0033] The detailed size diagram of the sharpening device is shown in Figure 1 ~ Figure 3 , in this embodiment, it is a sharpening device designed for sharpening a common drill with a diameter of...

Abstract

The invention discloses a method and a device for manually sharpening a drill bit. The device comprises a template main body (1). A cylindrical groove (2) is opened on the surface of the template main body (1). And there is a same plate head (3) along the axial direction of the cylindrical groove (2), and the model head (3) includes a plane end face tangent to the cylindrical groove (2), and the model head (3) is on the plane end face There is a tip (4) at the end of which is equal to the front angle of the drill bit, and the two sides of the tip (4) are connected with the template main body (1) through arc edges (5). The invention improves the sharpening efficiency of ordinary operators and solves the problem of poor processing effect after the drill is sharpened due to unqualified sharpening technology.

Description

technical field [0001] The invention relates to a method and a device for rapid manual sharpening of ordinary drill bits, and belongs to the technical field of mechanical processing. Background technique [0002] With the reform and development of the manufacturing industry, CNC cutting tools have gradually replaced traditional ordinary cutting tools, but ordinary cutting tools sometimes play a unique role in the part manufacturing process. [0003] Especially for the sharpening of ordinary drill bits, a well-ground drill bit can drill more holes than a CNC alloy drill bit. Therefore, it is necessary to design a new method for sharpening drills, aiming at solving the three common disadvantages of traditional general sharpening drills: [0004] (1) The drill bit is offset, causing the length of the two main cutting edges to be inconsistent; [0005] (2) The height of the two main cutting edges is inconsistent; [0006] (3) The chisel edge is not on the center, and the cent...
