Description
The method of working composite rope groove of drum of the present invention (Lebus grooving) belongs to the Machining Technology category, relates to copying and digital control processing and complex art thereof.Particularly, be a kind of method that is mainly used to process the oil-well rig composite rope groove of drum, also be applicable to the processing of the large-scale hoist engine composite rope groove of drum of heavy industrial and mineral.
Composite rope groove is used for holding on the cylinder face of cylinder and the arranging steel wire rope, and it is combined at interval by cannelure and helicla flute.Its expanded view is seen accompanying drawing 2, and cannelure II, IV are used for holding rope, respectively account for 135 ° angle of circumference, differ 0.5 grooving vertically each other apart from S; Helicla flute I, III are mainly used to row's rope, respectively account for 45 ° angle of circumference, its pitch H=4S, and two sections helicla flutes are guided a grooving altogether apart from S, make steel cable transition row to the second circle grooving, so go round and begin again.The traditional handicraft of composite rope groove is that the cylinder top layer with grooving is separated from roller basal body, be decomposed into I, II, III, four fan-shaped frids of IV again, after the processing of finishing grooving and frid and surface thereof on the universal machine tools respectively, assembling is welded on roller basal body and is formed successively.There is the advanced total control technology of track shaping to finish the forming technique of composite rope groove abroad, though it can be on roller basal body the direct forming grooving, but because equipment investment costliness, for single and mini-batch production production, flute profile only is the grooving cylinder of extremely general machining accuracy and surface quality, also is difficult to replace for the moment traditional handicraft.
The object of the present invention is to provide a kind of economical rationality, easy to be reliable, what be easy to promote organically combines the Numeric Control Technology of traditional profile copying technology with the advanced person, directly the processing method of formed composite grooving on roller basal body.

Technical characterictic below in conjunction with the method for description of drawings working composite rope groove of drum of the present invention.
The method of working composite rope groove of drum of the present invention is characterized in that, is a kind of numerical control and profile copying technology to be combined that the direct method of formed composite grooving on cylinder realizes steps of the method are:
1. for ease of profiling and simplification numerical control campaign design, the compound curved surface that composite rope groove is combined by the annular surface of revolution and cylinder canal helicoid is reduced to the compound curved surface of being made up of the annular surface of revolution and circle helicoid.
2. the mother who simplifies compound curved surface encloses Γ center of circle motion trace and launches the broken line o-a-b-c-d as shown in accompanying drawing 3 in the plane, this broken line can be replaced by the skew lines od by 3 of o, b, d, the helix of inducing as the grooving compound curved surface, it induces helix parameter to be: Pv=(S)/(2 π), corresponding helicoid is called induces helicoid.
3. the profile of contour wheel depends on that the end of inducing helicoid cuts shape Ω, gets calibration o-xyz and moving mark o '-XYZ, sees accompanying drawing 4, and the equation of Ω is:
x＝〔（R+r）+rainψ〕Cosv
y＝〔（R+r）+rainψ〕sinv
z＝
- +r/PvCosψ
"-" number is used for right helicoid in the formula, and "+" is used for the left-hand screw face.Moving some parameter is
=3/2 π
- +Cos
-1(1-h/r), v is the motion parameter, and all the other symbolic significances are seen description of drawings.On the contour wheel profile each point radially arrive its Ji Quan apart from △=(R+h)-
。According to making the contour wheel profile to the method for designing of heart straight push disk cam, the contour wheel profile of the cylinder of different size and grooving is different according to the △ value.
4. the contour wheel that will manufacture and design is fixed on the lathe feed planker, the characteristics of motion of contour wheel is a kind of intermittent composite revolving motion, it turns round synchronously with machine tool chief axis (cylinder) on the one hand, and make cylinder revolution 0 °-45 ° with 180 ° of-225 ° of intervals in, contour wheel is to be four times in the rotational speed of main shaft, and 45 °-180 ° with 225 ° of-360 ° of intervals in, contour wheel stops at the final position that moves previously not to be changeed; Also must do the gyration that adds with inducing the definite screw angular displacement of helix parameter Pv institute on the other hand according to long feed amount l.Contour wheel rotates, by push rod and related with it hydraulic copying attachment, drive sharp knife and finish the processing of grooving, dimensional parameters according to processed cylinder and grooving thereof, select suitable engine lathe to carry out as shown in Figure 1 numerical control transformation, promptly disconnect between former machine tool chief axis and feed planker in get in touch mechanical drive train, replace the digital control system that comprises sensor, industrial control unit (ICU), servo and digital display device etc., make selected contour wheel do above-mentionedly clocklike to rotate according to the drum groove specification program of setting.Cylinder is done uniform rotation, the cutting speed decision that rotating speed is allowed by material, and the feed planker is made at the uniform velocity linear longitudinal movement, and feed is by material, cutting-in and the decision of flute profile surface roughness.
Drum groove can be shaped by one-pass in theory, cutter changes between full groove depth h from zero in each all cutting-in of main shaft, in fact when cable diameter is thick, often need 2-3 feed just can finish, in order to guarantee the repeatable position precision of each feed, require numerical control device to have backhaul step-by-step counting and zero-bit status display function.
The present traditional handicraft of the present invention and China is compared, because it is formed composite grooving on the cylinder face of cylinder directly, it is few to have other part, and structure is single, and technology is easy, the work efficiency height, quality is good and cost is low, compares with external total control technology, invest little, reliability is high, being convenient to maintenance and popularization, is the viable process scheme of comparatively economical rationality.
Most preferred embodiment: the processing of the composite rope groove of F320-3DH rig TF-38 winch drum: wirerope diameter d=35mm, cylinder name radius R=400mm, grooving radius r=19mm, groove depth h=8mm, grooving is apart from S=35.75mm, grooving surface roughness 3.2 μ m, flute profile error delta
1＜0.05mm, the slot pitch error delta
2＜0.05mm transforms three feeds of branch with lathe CW6180 and is shaped.Its concrete procedure of processing is:
1. processed grooving drum clip is held between machine tool chief axis chuck and tailstock, the speed of mainshaft is chosen to be about n=15 rev/min by the permission cutting speed of cylinder material.
2. select contour wheel to be installed on the profiling wheel shaft on the feed planker according to cylinder and grooving dimensional parameters, the feed of feed planker is by material, cutting-in, flute profile surface roughness and which time feed decision, cutting-in t
1=5mm, t
2=2.5mm, t
3=0.5mm, feed are l
1=1.2 millimeters/change l
2=1 millimeter/change l
3=0.25 millimeter/change.
3. the relevant dimensional parameters (R, h, r, s etc.) with cylinder and grooving is given by input keyboard.
4. start lathe and digital control system and hydraulic tracing control system, adjust cutter, machine until shaping by giving the motor-driven feed cutting of fixed cutting-in.
