Detailed description of the invention
A kind of carbide alloy drilling reamer as shown in figures 1-4, the shank comprising working portion and be connected as a single entity with working portion, working portion comprises the drilling portion 1 of the taper being arranged at working portion front end and the ream portion 3 after being connected to drilling portion 1.
Wherein drilling portion 1 as shown in Figure 1, the angle of drilling portion 1 taper angle is 120 °, and such angle can improve the intensity of whole drill bit cutter when drilling effect.Can change accordingly according to the parts of institute's drilling in actual use procedure.Drilling portion 1 comprises two drilling swords 4, two and is connected to the major first flank 5 of drilling sword 4 sidepiece and is connected to the second rear knife face 6 of major first flank 5 sidepiece, straight trough 15 is provided with between drilling sword 4 and the second rear knife face 6 of opposite side, for chip removal, straight trough 15 angle is generally greater than 90 °, and setting is the effect in order to increase chip removal like this.
As shown in Figure 2, the drill bit in figure according to being rotated counterclockwise, the seamed edge cutting workpiece of drilling sword 4.Major first flank 5 is provided with the interior cold hole 7 running through whole cutter.After second, knife face 6 is provided with guiding gutter 8.In use procedure, by passing into the temperature that cooling fluid reduces cutter in inside cold hole 7, prevent cutter from causing tool strength to reduce because drilling produces high temperature.
In order to promote that the chip occurred in drilling process blocks boring, pinning cutter causes cutter impaired, also knife face 6 is provided with guiding gutter 8 in the second rear, wherein guiding gutter 8 one end is communicated with interior cold hole 7, knife face 6 after the other end runs through second, guiding gutter 8 is by interior cold hole 7 and straight trough 15 UNICOM between drilling sword 4 and the second rear knife face 6 of opposite side.So in use, only need chip to be washed away by cooling fluid.
In practical application, the chip of generation needs enough space, therefore by slope shape tapered for whole Tool Design.When whole cutter is standing state, drilling sword 4 and the first connecting line 13 of major first flank 5 are positioned at the top of the second connecting line 14 of major first flank 5 and the second rear knife face 6, namely the end face of drilling sword 4 is in different planes from the end face of major first flank 5, major first flank 5 is domatic for what tilt, is conducive to the discharge of chip.
Second connecting line 14 of major first flank 5 and the second rear knife face 6 is positioned at the top in knife face 6 opposite side sideline after second, and this object arranged also is the discharge being beneficial to chip, the second rear knife face 6 is designed to inclined plane, is conducive to increasing the space of discharging chip.
A kind of preferred scheme is, the chamfered edge 10 of ream effect has been provided with in drilling sword 4 and shoulder 2 junction, chamfered edge 10 is 45 ° with the sideline angle of shoulder 2, drilling portion 1 is when drilling, this chamfered edge 10 1 aspect can play the effect of ream, can carry out smooth modification on the other hand to the parts of drilling.
What whole cutter mainly played ream effect is ream portion 3, and ream portion 3 is connected with drilling portion 1 by shoulder 2, and ream portion 1 comprises the cone gear form ream sword 9 being connected to shoulder 2.
As shown in Figure 3, the cutting edge place of ream sword 9 is designed with stabilising surface 11, and the angle that stabilising surface 11 and straight trough 15 are positioned at the cell wall 15.1 that ream sword 9 sections is located is 89 °, and the width of stabilising surface 11 is 0.5mm.The effect in design stability face 11 carries out ream modification to processing work on the one hand, can play the effect of stable support on the other hand to drilling portion 1.Wherein the sword face width degree of stabilising surface 11 is 0.5mm.
During use, by bit alignment processing work, rotary cutter, drilling sword 4 rotates drilling processing work, and it is smooth that the 10 pairs of workpiece of the chamfered edge above drilling sword 4 carry out modification.It is smooth that cutting edge on shoulder 2 also can carry out ream to machining hole.When cutter rotates into the ream sword 9 of cone gear form, carry out rotation ream machining, process the hole of taper by ream sword 9 pairs of machining holes, wherein stabilising surface 11 can carry out ream machining to whole hole.The hole machined is front end is blind cylindrical hole, and the rear end of cylindrical hole is the blind hole of taper.
The utility model, on the basis of existing straight-flute drill, optimizes the structure of Cooling Holes, improves chip removal and cooling effect, avoids chip removal freely not cause the problem such as surface tear and cutter clamping stagnation.Additionally by improving drill bit blade and cone toothing, improving precision and the surface quality in hole, not needing independent fraising also to meet quality requirement, shorten process time simultaneously.
