Abstract
The utility model relates to the field of reamers, and particularly relates to a double-blade type reamer for processing micropores. The double-blade type reamer for processing micropores comprises a guiding part (1), a tool bit frame (2) and a handle (3), wherein the guiding part (1), the tool bit frame (2) and the handle (3) are connected in sequence and the central axes of all the three are superposed; the section of the tool bit frame (2) is linear shaped; and the tool bit frame (2) and the handle (3) are in smooth transition. The device is characterized by also comprising cutting blades (4) and cutting edges (5), wherein the cutting blades (4) are fixed on the outer edges of two fixed surfaces along the bus direction of the tool bit frame (2); the two fixed surfaces are vertical to the end surface of the tool bit frame (2); two cutting edges (5) are respectively arranged on the outer edges of the cutting blades (4); and the top ends of the cutting edges (5) are connected with the outer edge of the bottom end surface of the guiding part (1). The double-blade type reamer is high in processing precision, easy to replace, low in cost, wide in range of application and long in service life.
Description
Technical field
The utility model relates to the reamer field, is specially a kind of twolip type reamer for capillary processing.
Background technology
The hole processing of diameter below 5mm is capillary processing, during capillary processing, because length and the diameter in hole are larger than generally, therefore the rigidity of cutter is relatively poor, cutter is in again in the encirclement in hole simultaneously, radiating condition is poor, chip discharge difficulty, and the methods such as boring commonly used are difficult to the crudy that reaches higher at present.
The utility model content
In order to overcome the defective of prior art, provide a kind of machining accuracy high, easily change, cutting tool cheaply, the utility model discloses a kind of reamer for one-shot forming processing choke valve valve body.
The utility model reaches goal of the invention by following technical solution:
A kind of twolip type reamer for capillary processing, comprise guide part, cutter head frame and handle, guide part, cutter head frame are connected with handle and are connected and three's central axes, the cross section of cutter head frame is yi word pattern, smooth transition between cutter head frame and the handle, it is characterized in that: also comprise cutting blade and cutting edge, cutting blade is fixed on the outer rim of two stationary planes vertical with cutter head frame end face along the generatrix direction of cutter head frame; Article two, cutting edge is located at respectively the outer rim of cutting blade, all is connected outer rim and connects in the top of cutting edge with the guide part bottom face.
Described twolip type reamer for capillary processing, it is characterized in that: the diameter of establishing guide part is a, and the distance between two cutting edge outer rims is b, and the diameter of handle is c, then a＜b, and b≤3mm, and b＜c, and c≤4mm; The angle of cut of the top of cutting edge and cutter head frame cross section side is at 100 °～120 °.
When the utility model used, cutting edge can adopt polycrystalline diamond (be Polycrystalline diamond, the be called for short PCD) cutter head that is welded and fixed, and adds man-hour, and guide part inserts in the blank hole in advance, and cutting edge plays shear action subsequently; Along with the lasting feeding of cutter head frame, can finish the processing to micropore.
The utility model adopts double-point tool, has increased the space between cutter and the hole, is convenient to heat radiation, chip removal and injection cooling fluid, has improved crudy.
The beneficial effects of the utility model are: machining accuracy is high, easily change, and low cost, applied widely, long service life.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model.
The specific embodiment
Below further specify the utility model by specific embodiment.
Embodiment 1
A kind of twolip type reamer for capillary processing comprises guide part 1, cutter head frame 2, handle 3, cutting blade 4 and cutting edge 5, and as depicted in figs. 1 and 2, concrete structure is:
Guide part 1, cutter head frame 2 are connected with handle successively and are connected and three's central axes, and the cross section of cutter head frame 2 is yi word pattern, smooth transition between cutter head frame 2 and the handle 3;
Cutting blade 4 is fixed on the outer rim of two stationary planes vertical with cutter head frame 2 end faces along the generatrix direction of cutter head frame 2; Article two, cutting edge 5 is located at respectively the outer rim of cutting blade 4, all is connected the outer rim of bottom face and connects in the top of cutting edge 5 with guide part.
If the diameter of guide part 1 is a, the distance between two cutting edge 5 outer rims is b, and the diameter of handle 3 is c, present embodiment a=2.5mm, b=2.8mm, c=4mm; The angle of cut of the top of cutting edge 5 and cutter head frame 2 cross section sides is that the θ among Fig. 2 is 110 °.
When present embodiment used, cutting edge 5 can adopt polycrystalline diamond (be Polycrystalline diamond, the be called for short PCD) cutter head that is welded and fixed, and adds man-hour, and guide part 1 inserts in the blank hole in advance, subsequently 5 shear actions of cutting edge; Along with the lasting feeding of cutter head frame 2, can finish the processing to micropore.
