Description
Technical field
The present invention relates to machine cut technical field of processing equipment, more particularly to a kind of reaming bit.
Background technology
Meeting often in machining at present needs behind processing hole due to design or repair mechanical engagement, need the situation of progress reaming, common processing method is that counterboring hole is carried out in original hole position with bigger drill bit, the boring bar tool of many types is generated therefrom, there is deep hole counterboring hole combination unit, there is high-speed cutting to bore flat-bottom hole instrument etc., but during especially the reaming of Refractoloy is processed in the processing of hard alloy, due to existing normal drill bit, it is many to be made of high-speed steel, the cutting temperature that drill bit often occurs in the reamer of Refractoloy is very high, the drilling part of drill bit is caused to produce the heat treatment phenomenon such as annealing, and Refractoloy produces thawing in working angles and is attached to the first-class phenomenon of drilling tool, so that its hardness is reduced, wear extent is big, drilling efficiency declines, service life is short, cause production cost higher.
In order to solve this interference problem, occurs a kind of drill bit CN 202087877 for drilling machine at present
U cools down drill bit using the mode of water cooling, but it is due to the cooling for being only provided with drilling rod center, the outside machined surface of drill bit can not directly be cooled down, and process tool only has fore-end, there is the process that rear portion is finish reamed in whole reaming, the rear portion of drill bit can not produce cutting well, still suffer from drilling tool annealing and nickel base heat resistant closes the phenomenon for producing and melting and being attached to drilling tool rear end part.
The content of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, there is provided a kind of reaming bit, solve to melt attached problem in whole Refractoloy well by the way of coolant is passed through in cutter, can realize and reaming processing is carried out in the material of Refractoloy and one-time formed technical process is finish reamed.
To solve problems of the prior art, the concrete technical scheme of use is：
A kind of reaming bit, including the first cutting edge, the second cutting edge, the 3rd cutting edge, the 4th cutting edge, Morse taper shank, lateral surface Cooling Holes, cutting slot, center Cooling Holes；First cutting edge is arranged on a kind of front end face of reaming bit；Second cutting edge is arranged on after the first cutting edge；3rd cutting edge is arranged on after the 4th cutting edge；4th cutting edge is arranged on after the 3rd cutting edge；The Morse taper shank is arranged on a kind of rear portion of reaming bit；The center Cooling Holes are arranged on a kind of central shaft of reaming bit, and the lateral surface Cooling Holes are arranged between the first cutting edge and the second cutting edge and are connected with center Cooling Holes；The cutting slot is arranged on a kind of first half of reaming bit and passes through the first cutting edge, the second cutting edge, the 3rd cutting edge and the 4th cutting edge.
It is preferred that scheme, first cutting edge, the second cutting edge, the 3rd cutting edge, the front portion of the 4th cutting edge are respectively provided with the conical surface.
Further preferred scheme, the center Cooling Holes run through a kind of reaming bit, and front end has the amplification conical surface.

In whole reaming and reaming procedure, first cutting edge assume responsibility for most resistance to cutting and heat, due to being provided with center Cooling Holes and lateral surface Cooling Holes so that the first cutting edge has obtained at utmost cooling, solve nickel base heat resistant and close the phenomenon for producing and melting and being attached on drilling tool.And coolant is moved upwards with scrap in cutting slot, further cool the second cutting edge, the 3rd cutting edge, the 4th cutting edge, it is ensured that the fraising quality of internal surface of hole, improve surface roughness.
By using such scheme, compared with prior art, it has technical effect that a kind of reaming bit of the invention：
1. a kind of reaming bit center Cooling Holes and lateral surface Cooling Holes, so that the first cutting edge that assume responsibility for most resistance to cutting and heat has obtained at utmost cooling, solve nickel base heat resistant and close the phenomenon for producing and melting and being attached on drilling tool, extend the service life of drill bit.
2. a kind of reaming bit is provided with the second cutting edge, the 3rd cutting edge and the 4th cutting edge, the one-shot forming of reaming and fraising can be completed, production efficiency is improved, multiple cutting edges make it that the roughness of hole surface is higher.
3. a kind of reaming bit is provided with Morse taper shank, it is ensured that the interchangeability of existing process equipment, the scope of application is more extensive.
