Abstract
The invention discloses a filling method for integral impeller milling processing vibration damping and belongs to the technical field of machining. The filling method comprises the following steps of 1, vertically arranging axial-flow type integral impeller part blades subjected to rough milling, and arranging a pouring protection clamp around the part blades, 2, uniformly coating blade margin plates and the surfaces of U-shaped groove cavities close to the blade margin plates with a release agent, and uniformly coating the blades close to a channel and the surface of the channel with the release agent, 3, pouring a filler into a container, and putting a sponge block into the container, 4, taking out the sponge block filled with the filler, putting the sponge block between the two adjacent blades and firmly pasting the sponge block to the surfaces of the blades and to other sponge block, 5, carrying out secondary filling on the blade root with the sponge block filled with the filler, and 6, carrying out standing for time of t and dismounting the pouring protection clamp so that the filling process is finished. The filling method can effectively improve blade rigidity, reduce vibration, protect a cutter and improve processing efficiency and quality.
Description
Technical field:
The invention belongs to Machining Technology field, be specifically related to a kind of integral wheel Milling Machining vibration damping fill method.
Background technology:
Large-scale axial flow type integral wheel is comparatively large because blade overhangs, and add man-hour at blade finish-milling, whole blade all can produce vibration.The vibration of blade reduces machined surface quality, and simultaneously due to blade vibration, processing feeding is difficult to increase, and has a strong impact on working (machining) efficiency, and comparatively large to the aging effects of cutter, therefore needs in large-scale axial flow type integral wheel finish-milling process to adopt damping technology.
Damping technology conventional at present has two kinds, and one is the flexible material of filling plasticine class between two blades, and this material is easily filled, packing material can be reused, but because packing material is softer, filler can only play the effect absorbing blade vibration energy, can not increase blade rigid; Two is between two blades, fill paraffin class vibration damping filler, such material can increase a part of rigidity of blade, also can absorbing vibrational energy, shortcoming is containing grease in paraffin, can not fit completely with blade, blade rigid increases not obvious, and the fusing of paraffin class material require, easy initiation fire in fusion process.
Summary of the invention:
For solving prior art Problems existing, the present invention proposes a kind of effectively can reduce finish-milling process axis streaming integral wheel blade vibration, increase blade rigid, protect cutter and improve the integral wheel Milling Machining vibration damping fill method of working (machining) efficiency and quality.
For realizing above object, the present invention by the following technical solutions: a kind of integral wheel Milling Machining vibration damping fill method, comprises the following steps:
Step one: axial-flow type integral wheel part blade complete for rough milling is vertically placed, set cast Protecting clamping apparatus around part blade;
Step 2: at blade listrium position and the U-type groove housing surface uniform application releasing agent near blade listrium, at blade and the water passage surface uniform application releasing agent of close runner;
Step 3: filler is poured in a container, then sponge block is put into this container;
Step 4: the sponge block that will suction filler takes out, and to be placed between adjacent two blades and to ensure all closely to paste jail between sponge block and the surface of blade, between sponge block and sponge block;
Step 5: use the sponge block suctioning filler to carry out second time at blade root position and fill;
Step 6: time of repose t, pulls down cast Protecting clamping apparatus, completes filling.
Hardness after filler described in step 3, step 4 and step 5 solidifies is between webster hardness 30 ~ 35.
Filler described in step 3, step 4 and step 5 is mixed by MultiCast 5 and Hardner IS02.
Described MultiCast 5 is 1:1 with the proportioning of Hardner IS02, and mixing time is not more than 10 seconds.
The t of time described in step 6 is 20 minutes.
Beneficial effect of the present invention: effectively can increase blade rigid, reduces vibration, protects cutter and improve working (machining) efficiency and quality.
Accompanying drawing illustrates:
Fig. 1 is the filling mode schematic diagram of one embodiment of the present of invention;
Wherein: 1-blade, 2-is containing the first sponge block of filler, and 3-is containing the second sponge block of filler, and 4-is containing the 3rd sponge block of filler, and 5-pours into a mould Protecting clamping apparatus.
Detailed description of the invention:
Below in conjunction with drawings and Examples, the present invention is described in further details: a kind of integral wheel Milling Machining vibration damping fill method, as shown in Figure 1, fills according to following steps.
Step one: vertically placed by axial-flow type integral wheel part blade 1 complete for rough milling, sets cast Protecting clamping apparatus 5 around part blade, to prevent filler in filling process from overflowing, pollutes working environment;
Step 2: at blade listrium position and the U-type groove surface of wall uniform application releasing agent near listrium, blade within the scope of fan, runner 100mm and water passage surface uniform application releasing agent, these positions can not be arrived by milling in process, thus need smearing release agent, after facilitating processing, remove filler;
Step 3: pour in the plastic containers of suitable size by each for filler MultiCast 5 and Hardner IS02 1.2 kilograms of Quick uniforms, rapid stirring, then puts into this container by clean sponge block;
Step 4: the sponge block suctioning filler is taken out, first the concave surface of blade is filled the first sponge block 2 containing filler, then fill the second sponge block 3 containing filler at the convex surface of blade, ensure sponge block and blade 1, between sponge block and sponge block, all closely paste jail.
Step 5: use the 3rd sponge block 4 containing filler to carry out second time at blade root position and fill;
Step 6: leave standstill 20 minutes, after solidifying Deng filler, pull down cast Protecting clamping apparatus 5, complete filling, and start finish-milling processing, hardness after filler solidifies is about 30 (webster hardness), and its hardness enough improves the rigidity also effective vibration damping of blade, is unlikely to again the work affecting milling cutter.After finish-milling processing work, remove remaining filler.
