Embodiment 1

[0024] A new type of chip removal tool for thread processing with small diameter, such as figure 1 , figure 2 , image 3 As shown, it includes a mounting part, a cutting part and a cooling part. The cutting part and the cooling part are respectively installed on the mounting part. The mounting part includes a handle. Equipment, the cutting part includes blades, blade mounting grooves and blade fasteners, the blades are installed in the blade mounting grooves through the blade fasteners, the blade mounting grooves can be adjusted according to the blade structure, the cooling part includes cooling channels, and the cooling channels are along the blade The shank is arranged in the axial direction, and the mounting part is also processed with a winding part for the concentrated winding of linear metal chips generated during processing and a chip removal part for discharging granular metal particles. The structure of this embodiment is integrally formed.

[0025] The winding pa...

Embodiment 2

[0028] The difference from Embodiment 1 is that the length of the first platform is 32mm. If the first platform is too small, it will affect the chip hooking effect, and if it is too large, it will affect the rigidity of the tool. At this time, both the rigidity of the tool and the hooking of the chip groove can be ensured. Crumbs work best and achieve balance.

Embodiment 3

[0030] The difference from Example 1 is that the distance between the boss and the chip slot is 0 mm, the boss is the chip stopper, the side of the boss close to the first platform is the chip surface, and the distance between the chip surface and the first platform is The included angle is 90°, and the boss and chip slot together form a right-angle slot structure, which can also realize the chip hooking function.

Abstract

The invention discloses a novel small-pipe-diameter thread machining chip removal tool, and relates to the technical field of machining tools. According to the technical scheme, the novel small-pipe-diameter thread machining chip removal tool is characterized by comprising a mounting part, a cutting part and a cooling part, the cutting part and the cooling part are mounted on the mounting part, and the mounting part is further provided with a winding part capable of allowing linear metal chips generated during machining to be wound in a concentrated manner and a chip removal part capable of allowing granular metal particles to be discharged. The novel small-pipe-diameter thread machining chip removal tool has the effects of solving the problem that chip removal is difficult in the small-pipe-diameter thread machining process and avoiding the conditions of cutter tipping, cutter wear acceleration and product smoothness reduction.

Description

technical field [0001] The invention relates to the technical field of machining tools, more specifically, it relates to a novel small-diameter thread machining chip removal tool. Background technique [0002] Definition of small pipe diameter: The pipe diameter of the workpiece that needs to be processed with threads is 3.5 inches and below, which is a small pipe diameter. [0003] In the small diameter precision thread forming process, due to the small diameter, the iron filings will be spirally curled during the production process and the iron filings are not easy to break, the iron filings will be curled and entwined in the pipe, resulting in the iron filings after the thread processing is completed. The situation in the accumulation tube, so it will be difficult to remove chips during processing. Therefore, it is prone to tool chipping, accelerated tool wear, and decreased product finish. Moreover, the iron filings in the piled pipe need to be manually dragged out fro...
