Problems solved by technology

[0002] The existing ceramic thread cutters usually use conventional included angles such as 30 degrees for their blade surfaces, but these thread cutters will cause problems such as "blocked" and "not straight" in the processed threads during production and processing, thus affecting processing efficiency and yield

Embodiment 1

[0024] The screw cutter in the present embodiment comprises cutter bar 100 and cutter head 200, and cutter head 200 main body is nearly disc shape, as figure 2 As shown in a, the cutter head 200 is formed with a blade portion, and the blade portion includes a first blade surface 201 and a second blade surface 202, and the first blade surface 201 and the second blade surface 202 are two opposite surfaces of the disc and are oppositely arranged. The continuous blade structure formed at the circumferential position of the cutter head 200, the surface where the blade tip is formed by connecting the first blade surface 201 and the second blade surface 202 is the interface 001, and the angle between the first blade surface 201 and the interface 001 The angle between the second blade surface 202 and the interface 001 is 28°. The cutter head 200 includes a main body made of alloy and a brazing layer formed on the surface of the main body. The brazing layer includes abrasive disperse...

Embodiment 2

[0026] The screw cutter in this embodiment includes a cutter bar 100 and a cutter head 200. The cutter head 200 has a nearly disc-shaped main body. The cutter head 200 is formed with a blade, and the blade includes a first blade surface 201 and a second blade surface 202. The first blade surface 201 and the second blade surface 202 are two opposite faces of the disc and are arranged oppositely. The blade portion is formed in a continuous blade structure at the circumferential position of the cutter head 200, and is connected with the first blade surface 201 and the second blade surface 202. The surface where the blade edge is formed is the interface 001, the angle between the first blade surface 201 and the interface 001 is 28°, and the angle between the second blade surface 202 and the interface 001 is 27°. The cutter head 200 includes a main body made of alloy and a brazing layer formed on the surface of the main body. The brazing layer includes abrasive dispersed on the sur...

Embodiment 3

[0028] The thread cutter in this embodiment includes a cutter bar 100 and a cutter head 200. The cutter head 200 has a nearly disc-shaped main body and has a protruding three-point structure outside the circumference of the disc (that is, three protruding blades are formed, The three points here do not refer to the three equal parts in the strict mathematical sense. Reasonable deviations are allowed to meet the operating requirements of the thread cutter. Of course, three equal parts are the optimal solution), such as figure 2 As shown in b, the blade portion includes a first blade surface 201 and a second blade surface 202, so that the blade portion is formed as a discontinuous blade structure at the circumferential position of the cutter head 200, connected with the first blade surface 201 and the second blade surface 202 The surface where the blade tip is formed is the interface 001, the angle between the first blade surface 201 and the interface 001 is 27°, and the angle b...

Abstract

The invention discloses a screwer comprising a screwer rod and a screwer head, a blade part is formed on the screwer head and comprises a first blade face and a second blade face, and the included angle between the first blade face and the second blade face is 55 + / -1 degrees. According to the scheme, the optimally designed screwer head structure is adopted, so that more excellent thread machining performance is achieved, and the machining efficiency is higher while the machining quality is improved.

Description

technical field [0001] The invention relates to the field of thread processing, in particular to a thread cutter and a device. Background technique [0002] Most of the existing ceramic thread cutters use conventional included angles such as 30 degrees for their blade surfaces, but these thread cutters will cause problems such as "blocked" and "not straight" in the processed threads during production and processing, thereby affecting processing efficiency and yield. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide a thread cutter and device, which can effectively improve the inherent defects of traditional ceramic thread...
