Technical field
The invention belongs to metal knife former technical field, be specifically related to knife face insertion packing Linear cut building mortion after a kind of fluted drill.
Background technology
For standard fluted drill, according to cutting requirement, will reach two objects after sharpening, one is that the distribution of relief angle on main cutting edge answers outer rim little, larger the closer to brill core, and should have suitable chisel edge angle and the forward and backward angle of chisel edge; Two is that the linearity of requirement main cutting edge is good.
Knife face sharpening technique after existing fluted drill, extensively adopts emery wheel sharpening, has Taper section sharpening method, helicoid sharpening method, plane sharpening method, hyperboloid sharpening method and face of cylinder sharpening method etc. particularly.Emery wheel sharpening method exist subject matter be: sharpening equipment complex structure, easily produce grinding burn, production efficiency is lower.
Summary of the invention
The object of this invention is to provide knife face insertion packing Linear cut building mortion after a kind of fluted drill, solve existing emery wheel Sharpening device complex structure, easily produce grinding burn and the low problem of production efficiency.
The technical solution adopted in the present invention is, knife face insertion packing Linear cut building mortion after fluted drill, comprise frame and fluted drill, frame is fixed with rolling guide-rail pairs and screw pair, rolling guide-rail pairs is all connected with connecting plate with screw pair, connecting plate is connected with rotating disk, and fluted drill is clamped by collet and is arranged on rotating disk.
Feature of the present invention is also,
Rolling guide-rail pairs comprises 4 way blocks and guide rail, and 4 way blocks are contained on connecting plate, and connecting plate can be moved linearly along guide rail by way block, and guide rail is fixed in frame.
Screw pair is comprised bearing block and is arranged on the leading screw in bearing block by bearing, and leading screw is connected with nut, and nut is arranged on connecting plate, and bearing block is arranged in frame.
Connecting plate is connected with rotating disk by screw, and rotating disk can at the cylinder upper rotary 0-90 ° of connecting plate.
The invention has the beneficial effects as follows, knife face insertion packing Linear cut building mortion after fluted drill of the present invention, sharpening is easy, does not need the rotation of the knife face place cone centre of gyration after fluted drill.Compared with existing emery wheel sharpening method, without grinding burn, without grinding force, do not produce rear knife face grinding burn, do not affect by cutter material and tool dimension, the fluted drill of the energy various conduction cutter material of sharpening and dimensions.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Knife face insertion packing Linear cut building mortion after fluted drill of the present invention, as illustrated in fig. 1 and 2, comprise frame 1 and fluted drill 9, frame 1 is fixed with rolling guide-rail pairs and screw pair, rolling guide-rail pairs and screw pair are all connected with connecting plate 5, connecting plate 5 is connected with rotating disk 7, fluted drill 9 is clamped by collet 8 and is arranged on rotating disk 7.
Rolling guide-rail pairs comprises way block 4 and guide rail 2,4 way blocks 4 are contained on connecting plate 5, and connecting plate 5 can be moved linearly along guide rail 2 by way block 4, and connecting plate 5 is connected with rotating disk 7 by screw, and rotating disk 7 can at the cylinder upper rotary 0-90 ° of connecting plate 5, guide rail 2 is fixed in frame 1.
Screw pair is comprised bearing block 11 and is arranged on the leading screw 3 of bearing block 11 li by bearing 10, and leading screw 3 is connected with nut 6, and nut 6 is arranged on connecting plate 5, and bearing block 11 is arranged in frame 1, and handwheel 12 is equipped with in the end of leading screw 3.
Operation principle of the present invention is, fluted drill 9 is clamped by collet 8, adjusts the initial position of fluted drill 9 during clamping, collet 8 is arranged on rotating disk 7, turn round around the cylinder of connecting plate 5 together with rotating disk 7,45 ° should be turned over for standard fluted drill, tighten with screw; Connecting plate 5 is connected with leading screw 3 by nut 6, rotating handwheel 12 can make connecting plate 5 realize moving up and down along guide rail 2, for adjusting the relative position of fluted drill 9 relatively between electrode wire of wire-cutting machine tools 13, whole device is fixed on the workbench of electric spark linear cutting machine by frame 1.When after standard fluted drill, knife face Linear cut is shaped, adjustment fluted drill 9 is 45 ° relative to angle between vertical direction, utilize electrode wire of wire-cutting machine tools cone adjusting degree function, angle between adjustment electrode wire of wire-cutting machine tools 13 and vertical direction is 14 °, the distance between fluted drill 9 and electrode wire of wire-cutting machine tools 13 is adjusted again by handwheel 12, the rectilinear movement function of recycling wire electrode cutting bench, adjust the horizontal range between the centre of gyration of fluted drill 9 and electrode wire of wire-cutting machine tools 13, then, utilize the circular interpolation function of wire electrode cutting bench, the electric discharge galvanic corrosion of electrode wire of wire-cutting machine tools 13, carry out the shaping of the rear knife face of fluted drill 9.
By the way, after fluted drill of the present invention, knife face insertion packing Linear cut building mortion solves the low problem of existing emery wheel Sharpening device complex structure, easily generation grinding burn and production efficiency, after fluted drill of the present invention, knife face insertion packing Linear cut is shaped to dress up and describes easily, does not need the rotation of the knife face place cone centre of gyration after fluted drill.Compared with existing emery wheel sharpening method, lack a gyration, circular interpolation is utilized to realize the shaping of knife face after fluted drill, and without grinding burn, without grinding force, do not produce rear knife face grinding burn, do not affect by cutter material and tool dimension, the fluted drill of the energy various conduction cutter material of sharpening and dimensions.
