Description

Taper hole cutting tool for graphite material processing

technical field

The utility model belongs to the field of cutting tools, in particular to a cutting tool for machining taper holes of graphite materials.

Background technique

In the 1960s, copper was widely used as an electrode material, with a usage rate of about 90%, and graphite was only about 10%. In the 21st century, more and more users began to choose graphite as an electrode material, which has good conductivity. And plasticity, and compared with the high purchase cost of copper electrodes, cheap graphite electrodes are very popular in the processing industry.

There is an essential difference between graphite processing and copper processing, and the consumption of graphite and copper in tool processing is also different; when processing tapered holes, the processing of copper tapered holes can only be completed by CNC machine tools, which can guarantee the processing accuracy, but for graphite materials In terms of processing, it has lower requirements for cutting tools, so that the processing of tapered holes can be completed by milling machines, but it is necessary to process tapered cutting tools, which leads to the same processing cost.

Utility model content

The technical problem to be solved by the utility model is to provide a graphite material processing taper hole cutter, which is simple in structure, convenient and practical. Processing costs.

A kind of tool for processing taper hole of graphite material, including drill bit, fixed sleeve, cone blade and bolt, said fixed sleeve is set on the drill bit and fixed by bolt, and said cone blade is connected on the fixed sleeve; said fixed sleeve includes A ferrule and a fixing bolt, the ferrule is provided with at least one slit for inserting a conical blade, and the conical blade is fixed in the slit by the fixing bolt.

Preferably, the middle part of the drill bit is provided with an extended sipe, and the end of the conical blade away from the sipe is arranged in the extended sipe.

Preferably, the distance between the extended sipe and the cutting end of the drill bit is 10mm to 20mm.

Preferably, the depth of the extended sipe is 2mm to 5mm.

Beneficial effect:

(1) A graphite material processing taper hole tool of the present utility model has a simple structure, is convenient and practical. By replacing the taper blades with different inclinations, it can process holes with different taper degrees, so that the processing difficulty of the taper hole is reduced and the processing cost is reduced.

(2) A graphite material processing taper hole tool of the present utility model, by fixing the taper blade on the drill bit, the bottom hole can be processed through the drill bit in advance, so that the subsequent taper hole processing is easier, and there is no need for separate processing to realize the taper hole. The holes are processed in one step.

Detailed ways

Further illustrate the embodiment of the present utility model below in conjunction with accompanying drawing.

Example 1

As shown in Figure 1; A kind of graphite material processing tapered hole tool includes drill bit 1, fixed sleeve 2, cone blade 3 and bolt, and described fixed sleeve 2 is sleeved on drill bit 1 and is fixed by bolt, and described cone blade 3 is connected to the fixing sleeve 2; the fixing sleeve 2 includes a ferrule 21 and a fixing bolt 23, and the ferrule 21 is provided with at least one slit 22 for inserting the cone blade 3, and the cone blade 3 is fixed by The bolt 23 is fixed in the sipe 22; the middle part of the drill bit 1 is provided with an extended sipe 11, and the end of the tapered blade 3 away from the sipe 22 is arranged in the extended sipe 11; the extended sipe 11 and the drill bit 1 cut The distance between the ends is 10mm to 20mm; the depth of the extended sipe 11 is 2mm to 5mm.

Specifically, when processing a tapered hole, replace the corresponding tapered blade 3 according to the inclination of the tapered hole. When installing the tapered blade 3, one end of the tapered blade 3 is inserted into the extended knife groove 11, and the fixing sleeve 2 is fixed on the drill bit 1 by bolts. , the cone blade 3 is fixed in the sipe 22 by bolts; the milling machine head drives the drill bit 1 to rotate, the drill bit 1 drives the fixed sleeve 2 to rotate, the fixed sleeve 2 drives the cone blade 3 to cut graphite, and the cone blade 3 cuts The bottom hole can be pre-processed by the drill bit 1 before, and it is more convenient to process the taper hole by the cone blade 3 after processing the bottom hole. Its traditional processing needs to process the bottom hole first and then process the cone hole wall, which saves processing steps; The distance between the sipe 11 and the cutting end of the drill bit 1 is set to 10mm to 20mm, which ensures that the head of the drill bit 1 has cutting force and is convenient for cutting powder discharge; by setting the depth of the extended sipe 11 to 2mm to 5mm, it can ensure that the cone blade 3 is inserted into it to prevent the end of the tapered blade 3 from affecting the diameter of the bottom hole and making the diameter of the small end of the tapered hole poor in accuracy.

The specific embodiments of the present invention have been described in detail above, but they are only examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the present invention fall within the scope of the present invention.
