Abstract
Provided is an internal cooling composite reamer. The internal cooling composite reamer comprises a reamer handle and a reamer body. The reamer body is provided with a plurality of layers of edge portions with different machining diameters. Cutting edges are inlaid on the edge portions. A central cooling water channel is disposed inside the reamer handle and the reamer body. Water outlet holes are arranged on transition portions between adjacent layers of edge portions. The water outlet holes are communicated with the central cooling water channel. Through arrangement of the particular cooling structure and the chip removing structure, cooling performance and chip removing performance of the reamer can be improved. Consequently, machining quality is improved, the service life of the reamer is prolonged, and use cost of the reamer is reduced.
Description
Technical field
The utility model relates to the cutter field of machining, particularly relate to a kind of in cooling combined reamer.
Background technology
Reamer is used for the hole after drilling (or reaming) processing on the ream workpiece, mainly is in order to improve the machining accuracy in hole, to reduce its surperficial roughness, is fine finishining and the semi-finished cutter that is used for the hole, and its allowance is generally very little.Along with the development of mechanical industry, the user is to having proposed requirements at the higher level delivery date of the crudy of product, process reliability, working (machining) efficiency, cutter etc.Wherein intracardiac cold hole cooling is leaned in the cooling of tradition reamer fully, has drawback: 1, not enough to the cooling of cutting edge, and cause surface smoothness relatively poor; 2, chip removal is undesirable, influences workpiece quality, reduces cutter life, causes machining efficient low.
The utility model content
The utility model is for addressing the above problem, propose a kind of in cooling combined reamer.
The technical scheme of the utility model is: cooling combined reamer in a kind of; Handle of a knife, cutter hub; Described cutter hub is provided with the blade of the different processing of several layers diameter, is inlaid with blade at blade, and described handle of a knife and cutter hub inside are provided with the center cooling-water duct; Transition portion between the blade of described adjacent layer is provided with apopore, and this apopore is communicated with the center cooling-water duct.
Described handle of a knife is the taper handle of a knife, and the rear portion of described center cooling-water duct is through to the afterbody of handle of a knife, and the front portion of described center cooling-water duct terminates in cutter hub inside, forms blind hole.
The transition portion of the blade diameter of described adjacent layer connects for the chamfering blades transition, and described apopore is positioned at the chamfering blades place.
Described apopore is some, is uniformly distributed with along the cutter hub periphery.
The beneficial effect of the utility model
In process, in reamer, inject cooling water through the handle of a knife end, cooling water flow is cooling-water duct through the center, after reamer is cooled off, finally discharges through apopore, simultaneously the iron filings that gathered in the chip area is gone out, and has improved the chip removal performance greatly.
The reamer of the utility model can improve the cooling performance and the chip removal performance of reamer through unique cooling structure and chip removal structure are set, thereby improves the service life of crudy, prolongation cutter, the use cost of reduction cutter.
