Description

Taper hole cutter for graphite material processing
Technical Field
The utility model belongs to the field of cutters, and particularly relates to a cutter for machining taper holes by using graphite materials.
Background
Copper is widely used as an electrode material in the 60 th century, the utilization rate is about 90%, and graphite is only about 10%; in the 21 st century, more and more users began to select graphite as an electrode material, which has good conductivity and plasticity, while at the same time, a low cost graphite electrode is deeply favored by the processing industry relative to the high purchase cost of copper material electrodes.
The graphite processing is essentially different from the copper processing, and the consumption of the cutter for processing the graphite is different from that of the copper; when the conical hole site is machined, the machining of the conical hole of the copper material can be finished only through a CNC machine tool, the machining precision can be guaranteed, but the requirements on a cutter are lower for the machining of the graphite material, so that the machining of the conical hole can be finished through milling machines, but the conical cutter is required to be machined, and the machining cost is not reduced.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a cutter for processing taper holes by using graphite materials, which has a simple structure, is convenient and practical, and can be used for processing hole sites with different taper degrees by replacing taper blades with different taper degrees, so that the processing difficulty of the taper holes is reduced, and the processing cost is reduced.
The cutter for machining the taper hole in the graphite material comprises a drill bit, a fixing sleeve, a taper blade and a bolt, wherein the fixing sleeve is sleeved on the drill bit and is fixed through the bolt, and the taper blade is connected to the fixing sleeve; the fixing sleeve comprises a ferrule and a fixing bolt, at least one cutter groove for inserting the conical blade is formed in the ferrule, and the conical blade is fixed in the cutter groove through the fixing bolt.
Preferably, an extension cutter groove is formed in the middle of the drill bit, and one end, away from the cutter groove, of the conical blade is arranged in the extension cutter groove.
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.
The beneficial effects are that:
(1) The cutter for processing the taper holes by using the graphite material has a simple structure, is convenient and practical, and can process hole sites with different taper angles by replacing the taper blades with different taper angles, so that the processing difficulty of the taper holes is reduced, and the processing cost is reduced.
(2) According to the cutter for machining the taper hole by using the graphite material, the taper blade is fixed on the drill bit, so that the bottom hole is machined in advance by the drill bit, the subsequent taper hole machining is easier, and the taper hole is machined in place in one step without separate machining.

Detailed Description
Embodiments of the present utility model are further described below with reference to the accompanying drawings.
Example 1
As shown in fig. 1; the cutter for machining the taper holes of the graphite materials comprises a drill bit 1, a fixed sleeve 2, a taper blade 3 and bolts, wherein the fixed sleeve 2 is sleeved on the drill bit 1 and is fixed through the bolts, and the taper blade 3 is connected to the fixed sleeve 2; the fixing sleeve 2 comprises a ferrule 21 and a fixing bolt 23, at least one cutter groove 22 for inserting the conical blade 3 is formed in the ferrule 21, and the conical blade 3 is fixed in the cutter groove 22 through the fixing bolt 23; an extension cutter groove 11 is formed in the middle of the drill bit 1, and one end, far away from the cutter groove 22, of the conical blade 3 is arranged in the extension cutter groove 11; the distance between the extended cutter groove 11 and the cutting end of the drill bit 1 is 10mm to 20mm; the depth of the extended sipe 11 is 2mm to 5mm.
Specifically, when the taper hole is machined, the corresponding taper blade 3 is replaced according to the inclination of the taper hole, when the taper blade 3 is installed, one end of the taper blade 3 is inserted into the extension cutter groove 11, the fixing sleeve 2 is fixed on the drill bit 1 through a bolt, and the taper blade 3 is fixed in the cutter groove 22 through bolt fixing; 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 conical blade 3 to cut graphite, a bottom hole can be machined in advance through the drill bit 1 before the conical blade 3 cuts, the conical hole is machined through the conical blade 3 after the bottom hole is machined, the traditional machining is that the bottom hole is machined firstly, and the machining step is saved; by setting the distance of the extended pocket 11 from the cutting end of the drill bit 1 to 10mm to 20mm, it is ensured that the head of the drill bit 1 has a cutting force while facilitating the discharge of the cut powder; by setting the depth of the extension sipe 11 to 2mm to 5mm, the insertion of the taper blade 3 therein can be ensured, and the occurrence of poor accuracy of the diameter of the taper hole small end due to the influence of the end portion of the taper blade 3 on the bottom hole aperture can be avoided.
The above description of the specific embodiments of the present utility model has been given by way of example only, and the present utility model is not limited to the above description of the specific embodiments. Any equivalent modifications and substitutions for the present utility model will occur to those skilled in the art, and are also within the scope of the present utility model. Accordingly, equivalent changes and modifications are intended to be included within the scope of the present utility model without departing from the spirit and scope thereof.
