Abstract

The invention belongs to a double-edge reamer which comprises a reamer handle (1) and a chip discharging groove (5). The double-edge reamer is characterized in that a hard alloy reamer head (2) is welded to the reamer handle (1), a plurality of first reamer points (4) and second reamer points (3) are machined on the reamer head (2), the included angle alpha 1 between each first reamer point (4) and the reamer head (2) is 40 degrees-50 degrees, and the included angle alpha 2 between each second reamer point (3) and the reamer head (2) is 25 degrees-35 degrees. Two kinds of holes with different diameters are machined through the reamer, the concentricity of the holes is high, labor and time are saved, machining efficiency is high, and quality is good.

Description

A kind of double blade reamer
Technical field
The invention belongs to machining tool, particularly a kind of double blade reamer.
Background technology
In machining; often have and require to process two holes that diameter is different in a hole; all selected the common drill bit of two different-diameters to process in the past; not only expenses of labour is high; if control badly, the concentricity in hole just there will be error, affects the quality of workpiece; even there is waste product, cause waste.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of employing once the hole that drilling tool can be processed to two different-diameters, a kind of double blade reamer that concentricity is high.
The technical scheme that technical solution problem of the present invention adopts is: a kind of double blade reamer, comprise handle of a knife and chip area, and it is characterized in that welding the cutter head of a carbide alloy on handle of a knife, on cutter head, process multiple points of a knife one and point of a knife two; The angle α of point of a knife one and cutter head 1it is 40 °~50 °; The angle α of point of a knife two and cutter head 2it is 25 °~35 °.
The invention has the beneficial effects as follows: this invention has realized with one cutter time processing is gone out to the hole of two kinds of different-diameters, and the concentricity in hole is high, saving of work and time, working (machining) efficiency is high, and quality is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is a kind of front view of double blade reamer;
Fig. 2 is the left side view of Fig. 1.
In figure: 1-handle of a knife; 2-cutter head; 3-point of a knife two; 4-point of a knife one; 5-chip area.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of double blade reamer, comprises handle of a knife 1 and chip area 5, it is characterized in that welding the cutter head 2 of a carbide alloy on handle of a knife 1, processes six points of a knife 1 and point of a knife 23 on cutter head 2; The angle α of point of a knife 1 and cutter head 2 1it is 40 °~50 °; The angle α of point of a knife 23 and cutter head 2 2it is 25 °~35 °.The quantity of point of a knife 1 and point of a knife 23 can be determined according to the material hardness of workpiece is different, and hardness is more much higher, and what hardness was low lacks.Handle of a knife 1 is selected ordinary steel.

Claims (1)

1. a double blade reamer, comprises handle of a knife (1) and chip area (5), it is characterized in that, at the cutter head (2) of a carbide alloy of the upper welding of handle of a knife (1), processing multiple points of a knife one (4) and point of a knife two (3) on cutter head (2); The angle α of point of a knife one (4) and cutter head (2) 1it is 40 °~50 °; The angle α of point of a knife two (3) and cutter head (2) 2it is 25 °~35 °.
