Description

A kind of reamer with interior cold-working
Technical field
The utility model relates to machining tool technical field, specifically a kind of reamer with interior cold-working.
Background technology
In mechanical processing process; people often encounter to be needed to process some endoporus; the common practice of current people is to adopt drill bit to get out endoporus; simultaneously in order to make the inner hole precision got out reach higher requirement; it is typically in after endoporus gets out and also needs to the suitable reaming of employing reamer or repair hole, improve the precision of endoporus with this. First get out endoporus; carry out reaming with reamer again or repair hole; the so successively method of two step processing endoporus; not only the course of processing is more complicated loaded down with trivial details; and particularly for processing endoporus deeper time; the concentricity machining rear endoporus would generally be made cannot to keep consistent, thus affecting the precision of endoporus. In order to make hole surface reach corresponding precision, also need to the hole being drilled is carried out polish, therefore, can only adopt other cutters that hole is processed separately, but so need to buy much knives tool, add processing cost, be unfavorable for saving production cost, and change cutter and also waste time and energy, also it is unfavorable for improving production efficiency.
Utility model content
The technical problems to be solved in the utility model is for Problems existing in background technology, it is provided that a kind of reamer with interior cold-working.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: a kind of reamer with interior cold-working, including overall cylindrical cutter hub and the knife bar of drilling and reaming, the described cutter hub that drills and reams includes drill bit segment, guide section, the section of finish reaming, described drill bit segment with the section of finish reaming are disposed radially three cutting tooth chip areas corresponding with quantity respectively, the diameter of described drill bit segment is less than the diameter of guide section, the diameter of described guide section is less than the diameter of the section of finish reaming, the diameter of the described section of finish reaming is less than the diameter of knife bar, described knife bar is provided with interior cold through hole, the described guide section drilled and reamed in cutter hub is provided with multiple oblique Cooling Holes connected with interior cold through hole respectively.
Further, described chip area is set to straight groove-like structure.
Further, described in its leading section of drill bit segment in cutter hub that drills and reams tapered, described cone point angle is 160 ��.
Further, it is connected for circular arc chamfering between described drill bit segment and guide section.
Further, it is connected for circular arc chamfering between described guide section and the section of finish reaming.
Further, it is connected for chamfering between the section of finish reaming with knife bar described in.
Further, described interior cold through hole is along being parallel in two of knife bar axis direction cold through hole, and the incline direction of the Cooling Holes being arranged on guide section to connect with interior cold through hole is obliquely installed towards drill bit segment direction.
Adopt a kind of reamer with interior cold-working of the present utility model, when processing through hole need not tool changing, reduce the usage quantity of cutter, it is to avoid much knives tool tool changing adds the error produced man-hour by the factor such as lathe, handle of a knife, improve the precision in processing hole, improve the quality of product; Simultaneously as be provided with interior cold through hole in knife bar, guide section is provided with the Cooling Holes connected with interior cold through hole, so can realize the cooling of reamer and processing work in time, extend the service life of cutter reamer, improve working (machining) efficiency. Therefore, there is simple in construction, reasonable in design, save the time for Set and Positioning, improve working (machining) efficiency, tool life, save processing cost, easy to operate, practical feature.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Shown in figure: drill and ream cutter hub, 11-drill bit segment, 12-guide section, the 12-section of finish reaming, 2-knife bar, 3-of 1-cuts cold through hole, 6-Cooling Holes in tooth, 4-chip area, 5-.
Detailed description of the invention
As shown in Figure 1, a kind of reamer with interior cold-working of the present utility model, including overall cylindrical cutter hub 1 and the knife bar 2 of drilling and reaming, the described cutter hub 1 that drills and reams includes drill bit segment 11, guide section 12, the section of finish reaming 13, described drill bit segment 11 with the section of finish reaming 13 are disposed radially three cutting tooth 3 chip areas 4 corresponding with quantity respectively, the diameter of described drill bit segment 11 is less than the diameter of guide section 12, the diameter of described guide section 12 is less than the diameter of the section of finish reaming 13, the diameter of the described section of finish reaming 13 is less than the diameter of knife bar 2, described knife bar 2 is provided with interior cold through hole 5, the described guide section 12 drilled and reamed in cutter hub 1 is provided with multiple oblique Cooling Holes 6 connected with interior cold through hole 3 respectively.
Further, described chip area 4 is set to straight groove-like structure.
