The speed of grinding head motor 17 is selected, and considers the liquid supply rate of cooling fluid treating stations, and the temperature restriction of grinding head motor 17 and the cooling requirement of emery wheel 8 thereof generally select for use 0~1500r/min to meet the demands.
The selection of emery wheel 8 because V-type, arc surface shear blade workpiece hardness to be processed are bigger, is generally HRC50-58, and heat treatment requirements quenches; Fineness is had relatively high expectations, and generally more than 0.8mm, and the Grinding Contact face is big, poor thermal conductivity, add and be easy to generate burn or crackle man-hour, should select softer emery wheel, select the green carbonization grain of R2-R3 for use, and the resin bond wheel of granularity in the 46-280 scope get final product.The size Selection of emery wheel 8 to consider workpiece to be processed arc surface 1, face 2 directly, the size of knuckle 3, V-type inclined-plane 4 and bistrique 7, the excircle dimension of emery wheel 8 must be less than the knuckle 3 and the arc surface 1 of workpiece, thickness is selected to get final product about 40mm, and the endoporus of emery wheel 8 is looked the size Selection of bistrique 7.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the parameter and the specification requirement of V-type to be processed, arc surface shear blade are as follows: material 4Cr5MoSiV shrinkage factor 1.5 ‰, V-type to be processed, arc surface shear blade Workpiece length 2500mm, thickness 90mm, the radius R 1 of arc surface 1 is 30000mm, 1.75 ° at 4 angles of inclination, V-type inclined-plane, the radius R 2 of the interlude knuckle 3 on V-type inclined-plane 4 is 265mm, heat treatment requirements quenches, hardness HRC 53~58, roughness requires 0.8, and flatness, the depth of parallelism and perpendicularity require 0.03.
(1), earlier workpiece to be processed is respectively faced directly 2, arc surface 1, V-type face 4 and relevant step surface carry out half finish-milling, equal every allowance 0.25+0.02mm, speed of mainshaft 600r/min during processing arc surface 1, each amount of feeding 0.3mm for guaranteeing the location benchmark.And unclamp pressing plate after processing, discharge stress, to reduce workpiece deformation.
(2) connect each mechanical part with reference to Fig. 4, Fig. 7, opened pump 13 then earlier, guaranteed that liquid circulation is normal.Start grinding head motor 7, test running 3~5 minutes, test running rotating speed 300r/min guarantees to work well.
(3) centering that is installed grinds workpiece after good, and parameter is selected as follows:
The linear velocity of a, emery wheel 8.Improve the linear velocity of emery wheel 8, the cutting edge number of participating in cutting in the unit interval is increased and the thickness of cutting attenuation, thereby can reduce the cutting edge surface roughness and boost productivity.But when the linear velocity of emery wheel 8 was high, grinding heat increased, thereby made cutting edge generation burn easily and burn out grinding head motor.In addition, when the linear velocity of emery wheel 8 was high, machine vibration was also bigger, is easy to generate defectives such as chatter mark and polygonal on cutting edge, and in order to guarantee workpiece quality, the linear velocity of emery wheel 8 is selected 10m/s for use.
B, moving speed of table.When correct grinding, workpiece is produced polygonal to moving speed of table and burn is influential.When moving speed of table improved, the polygonal degree of depth increased, and during minimizing, the polygonal degree of depth reduces, but crossed when low when moving speed of table, cutting edge is produced burn.Therefore, in order to guarantee workpiece quality, select 1300~1800mm/min for use.
C, length feed amount.The vertical feed amount of the also available milling machine ram 5 of length feed amount is represented.The length feed amount does not make significant difference to the cutting edge surface roughness within the specific limits, if but the length feed amount is too big, and then make cutting edge go out rib easily.Therefore,, when correct grinding, can adopt 5~10mm/ time, can adopt 0~5mm/ time during tarry matter in order to guarantee workpiece quality and to boost productivity.
D, lateral feed.When correct grinding, and the little sword that make cutting edge burn and go out rib and destroy emery wheel excessive for fear of cutting-in, lateral feed can not be excessive, particularly feed for the first time, if the amount of feeding is too big, not only can make cutting edge may produce burn and go out rib, and might destroy the little sword of emery wheel, thereby influence grinding efficiency.Therefore, in order to guarantee workpiece quality and to boost productivity, generally should make lateral feed less than 0.02mm/ time.
Tarry matter mainly is to reach low cutting edge surface smoothness requirement by the friction polishing action between emery wheel and cutting edge, and the surplus of this moment is very little, generally has only 5~10 μ m, so tarry matter, generally can only feed once just let alone tarry matter, until reaching the drawing requirement.Must not be as general grinding, when the workbench reciprocating reversing, repeatedly feed, this point should be specifically noted that, otherwise the surface smoothness of cutting edge not only can not improve, and will worsen on the contrary.
During grinding work piece, running check cooling fluid treating stations, guarantee that liquid circulation is normal, prevent that motor from burning out; Need to use the diamond pen trimming wheel before correct grinding and the tarry matter, prevent that workpiece from going out rib, and emery wheel need cool off fully, prevent workpiece burn.
Grinding attachment of the present utility model, by electric box bistrique is carried out the speed regulation and control, the cooling fluid treatment box cools off the embedded motor of bistrique, the cooling device that emery wheel cooling adopts milling machine to carry, utilize CNC planer type milling machine can by programming walk curved surface finish on V-type to be processed, the arc surface shear blade face directly and Machining of Curved Surface grinds.
Apparatus structure of the present utility model is simple, and is easy to loading and unloading, the V-type of being processed, arc surface shear blade, can satisfy drawing fineness and Geometrical Tolerance Principle fully, improve working (machining) efficiency greatly, saved blade, solved the processing difficult problem of high accuracy curved surface shear blade.
