Abstract
The utility model belongs to the technical field of cutting tools, and particularly relates to a reamer for processing aluminium alloy. The reamer is mainly used for processing sectional materials and plates and the like, which are made of aluminium alloy. The reamer comprises a reamer handle and a reamer arbor, wherein a reamer bit is arranged at one end part of the reamer arbor; the edge of the reamer bit is arranged in a chamfering way; a plurality of cutting edges are arranged in circumferential direction of the reamer arbor; a cuttings chute is formed between each cutting edge and an inclined surface in front of the cutting edge; a transitional surface is arranged on the back side of each cutting edge and connected with a previous inclined surface; the included angle between each cutting edge and the inclined surface in front of the cutting edge is 80 degrees; and the reamer bit is flat. The reamer provided by the utility model has the advantages of simple structure and practicability; a conical surface can not be formed at the bottom of a blind hole due to the flat reamer bit; and the cutting edges in the circumferential direction can be used for conducting out-of-tolerance bore machining during reamer feeding.
Description
Technical field
The utility model belongs to the cutting tool technical field, specifically is a kind of processing aluminium alloy reamer, and it is mainly used in section bar, sheet materials such as processing aluminium alloy.
Background technology
At present, in machining, new machining hole or the pre-hole of blank further added all will use reamer usually man-hour, especially carry out the hole at aluminium alloy extrusions and sheet material and add man-hour, more will use reamer, reamer is made up of shank and bar portion, and the gyratory directions of head evenly is provided with cutting edge, the center of cutting edge and reamer is 15 ° of angles, and all cutting edges form the tapering cutter head at gyratory directions.Add man-hour, have only the gyratory directions cutting, end face does not have the cutting function, therefore can only pacify former hole site and process, and when the position in hole is overproof, but can not revise it, in addition, when processing blind hole, can form tapering in the Kong De bottom.
Summary of the invention
The utility model proposes the processing aluminium alloy reamer that a kind of brill is used to process aluminium alloy extrusions, sheet material at the shortcoming that exists in the above-mentioned technology.
The technical scheme that realizes the utility model purpose is as follows:
Processing aluminium alloy reamer, it comprises handle of a knife and knife bar, the knife bar end is provided with cutter head, the cutter head edge chamfer is provided with, and knife bar is circumferentially with some cutting edges, constitutes chip area between the inclined-plane of cutting edge and its front, the cutting edge back side is provided with transition face, transition face is connected with a last inclined-plane, and the angle on cutting edge and inclined-plane is 80 °, and described cutter head is made as the plane.
Described transition face and tangential angle are 25 °.
The extended line of described cutting edge is by the center of circle of knife bar.
Advantage of the present utility model has simple in structure, practical, and the cutter head on plane can not form the conical surface in the blind hole bottom, and circumferential cutting edge can carry out overproof hole processing when feed.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
As shown in Figure 1 and Figure 2, processing aluminium alloy reamer, it comprises handle of a knife 1 and knife bar 2, knife bar 2 ends are provided with cutter head 3, cutter head 3 edge chamfer settings, chamfering is 45 °, and knife bar 2 is circumferentially with some cutting edges 21, constitutes chip area 23 between the inclined-plane 22 of cutting edge 21 and its front, cutting edge 21 back sides are provided with transition face 24, transition face 24 is connected with a last inclined-plane 22, and cutting edge 21 is 80 ° with the angle on inclined-plane 22, and described cutter head 3 is made as the plane.
Described transition face 24 is 25 ° with tangential angle.
The extended line of described cutting edge 21 is by the center of circle of knife bar 2.
