The sharp milling cutter adopts a double-blade structure; during working, the blade I is responsible for a main high-rate cutting task, and the blade II is responsible for finishing the support surface and cutting the chamfer shape of the root of the bolt supporting surface; and the blade I firstly performs cutting work, then the blade II follows up and performs finishing work, and accordingly, the blade I and the blade II are ingeniously matched, so that the processing efficiency of a connecting rod cap is improved, and the processing quality is greatly improved.
Description
Technical field
The utility model relates to a kind of bolt support surface Keen-edged milling cutter, belongs to the cutting-tool engineering field.
Background technology
High-power connecting rod is used for protecting bolt head and improves connecting rod cap intensity because the bearing capacity factor is designed to the powerful muscle shape of semicircle around the connecting rod cap bolt support surface when design.Normally with the processing of vertical knee-type milling machine slotting cutter, because the interrupted cut of cutter, cutter consumed high, and working (machining) efficiency workpiece quality stability low and that process is not high, often has larger defect rate, causes great waste in the past.
Simultaneously the powerful milling cutter of general machining center all is that identical two or 3 blades are uniform, finish cutting, but because the impact of blade width, cutting resistance increases, can not once-forming, our part requires the supporting surface root that the R3 angular shape is arranged, and general cutter can not be realized, must repeatedly process with nonstandard cutter or multitool, the cost of charp tool is high.
The utility model content
The utility model is for defects, and purpose is to provide a kind of simple in structure, with low cost and bolt support surface Keen-edged milling cutter with well processed effect.
The technical solution adopted in the utility model is for this reason: the utility model comprises blade one and blade two, and both are arranged at an angle front-back staggered setting on the cutter hub; Blade one main cutting edge is higher than blade two main cutting edge settings, and the main cutting edge of blade one is for being horizontally disposed with, and the main cutting edge of blade two has-2 ° to-5 ° inclination angle; Blade one is arranged on a side of cutter hub axis, and its radius of clean-up and to be processed 's radius is corresponding, and blade two also is arranged on axis one side.
The one segment distance setting of described blade two off-axis.
Described blade main cutting edge has-3 ° of angles.
Described blade one, blade two are 180 ° of arrangements.
Described blade one is higher than blade two 0.4mm and arranges.
The utility model has the advantages that: the utility model adopts the setting of double blade structure, and blade one is born main high-rate cutting task during its work, and cutter two is born supporting surface smoothing and bolt support surface root chamfer shape; Cutter one at first drops into cutwork, and cutter two carries out smoothing work, passes through so the ingenious cooperation of cutter one and cutter two, so that the working (machining) efficiency of connecting rod cap, crudy all are greatly improved.
Because the improvement of this blade unit and structure of the cutter body, the production efficiency of this operation has improved four times, and process quality is guaranteed.Main is, these two kinds of blades all are the old blades that finish-milling processing is changed, finish-milling processing mainly is to use nose angle, it is the blade that roughness does not reach requirement, and this powerful Keen-edged milling cutter mainly is to use knife face, add homemade blade row, two blades are born different cutting functions, and the cost of charp tool of this operation is original 1/5.

The specific embodiment
As shown in the figure, powerful Keen-edged milling cutter of the present utility model is synthetic by two different set of blades, select respectively 12.7 * 12.7 square blades 1,2 one-tenth 180 ° of arrangements of 16.5 * 9.5 diamond shaped insert, 12.7 square blade 1 face is born the hole central cutting, 9.5 diamond shaped insert, 2 faces are born external profile diameter φ 31 cuttings, and two blade functions are different, according to cutting principle and repetition test, square blade 1 is born main high-rate cutting task, and the cutter main cutting edge is higher than cutter center 0.4mm and arranges, and is beneficial to the steady of cutting; Diamond shaped insert 2 faces are born supporting surface smoothing and bolt support surface root R3 angular shape, and cutter main cutting edge and cutter center are high together, and negative 3 °, keen edge when making the knife face cutting reduces and cuts the vibration that produces, and guarantees supporting surface smoothing and root R3 angle roughness.With the M2 screw blade is fixed on the cutter hub 3 in the present embodiment, behind the blade clamping, according to the material of connecting rod. hardness, through the repetition test adjustment, selected best 1800 suitable rotating speeds, the cutting output of F 50, in the situation of interrupted cut, friction, stable cutting is light.
The utility model square blade is because its operating characteristic, the cross spider of its lower surface and side is main cutting edge, and for normally carrying out smoothly of cutting, the main cutting edge of square blade 1 is higher than diamond shaped insert 2 main cutting edge settings, through overtesting, in the present embodiment, its difference in height is 0.4mm, certainly for the cutting of other similar workpiece, its difference in height can be made flexible adjustment according to actual conditions;
The utility model selects-3 ° to be the design of making for supporting surface root R3 angular shape, if the root angle changes, its angle can be made respective change.
The selection of all angles all is to detect the preference data that draws through reality as shown in the figure.
Through detecting, the utility model cutter has following process data:
Processing a kind of connecting rod connecting rod cap bolt two supporting surfaces has diameter 31mm on one side, mills dark 30mm, and this workpiece material is 40Cr, material hardness HRc26-32; Two kinds of tool sharpening Data Comparisons: (Φ 31.5, dark 40/20) unit: mm.
