Description
Technical field
The present invention relates to Roots air blower curved face type processing technique field, and in particular to a kind of Roots air blower
Curved surface profile processing special machine presss from both sides milling cutter.
Background technology
Traditional Roots air blower type face processing mainly uses planing mode, and also there are machining accuracy is high, efficiency
It is low, the deficiencies of larger is lost in processing.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, and Roots air blower can be improved by providing one kind
Processing efficiency, impeller precision, reduce equipment, cutter loss Roots air blower curved surface profile processing special machine folder milling
Knife.
In order to solve the above technical problems, the concrete technical scheme of the present invention is as follows：A kind of Roots air blower curved face type
Line processing special machine folder milling cutter, is mainly made of, the cutter hub uses impeller profile cutter spindle, cutter hub, blade, axle sleeve, nut
Shape cutter hub, the blade are provided with curve cutting edge, and the blade is clamped in the cutter groove of cutter hub by screw.
Further, the cutting edge of the blade it is combined into curve include circular arc, involute, cycloid.
Further, the blade is formed by some groups, and the quantity of every group of blade is set according to impeller perimeter of section, every group of knife
Piece spirality is distributed in the cutter groove on cutter hub, and the blade on each position is provided with the blade of different curves, one group of blade
Effective cutting edge be to be combined into the impeller curve of Roots blower.
Further, the blade is positioned by two sides for withstanding axial and radial force.
Further, the blade is made of cemented carbide material.
Further, the blade is provided with hard alloy coating.
Further, the coating of the blade has TiC or TiN for surface recombination.
Further, the cutter hub is made of G35 cast steels or 45 carbon constructional quality steel materials.
The technical solution adopted in the present invention has the advantages that：The present invention is as a result of in impeller type cataract knife
The structure of fixturing blade on body, type face machining accuracy are almost solely dependent upon the precision of the machine folder milling cutter, therefore to improving impeller
Machining accuracy can play decisive role；Blade using step-by-step arrangement install, therefore can seriation, standardized designs manufacture, and
Can optimization design blade as needed distribution, loss of the working angles to machine tool, cutter, blade is effectively reduced.By
In employing forming technique, 1/3rd of the whole type face of primary feed completion arrives half, for processing larger rule
The impeller of lattice, 4~5 times can be improved than numerical control planing efficiency.The present invention is rational in infrastructure, easy to use, substantially increases Roots's drum
Draught fan impeller processing efficiency, impeller precision, reduce the loss of equipment, cutter.

Fig. 1 is schematic structural view of the invention；
Fig. 2 is blade positioning schematic diagram of the present invention；
Fig. 3 is blade distribution effect figure；
Fig. 4 is blade cut sword Overlay figure.
Embodiment
Further illustrate technical scheme below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, a kind of Roots air blower curved surface profile processing special machine folder milling cutter, mainly by cutter spindle 1, knife
Body 2, blade 3, axle sleeve 4, nut 5 form, and the cutter hub 2 uses impeller type wire cutter hub, and the blade 3 is provided with curve cutting
Sword, as shown in Fig. 2, the blade 3 is clamped in by screw 6 in the cutter groove of cutter hub 2, and by datum level A and withstands axial force
Positioning blade 3 is carried out in one side, it is ensured that the repetitive positioning accuracy of blade 3, so that the machining accuracy in guarantee type face.Due to impeller
Molded line is segmentation symmetrical curve, so blade 3 is preferably manufactured using Seriation Design, it is mutual to reduce use cost, raising blade
It is transsexual.
The cutting edge of the blade 3 it is combined into curve include circular arc, involute, cycloid.
The blade 3 is formed by some groups, and the quantity of every group of blade 3 is set according to impeller perimeter of section, and total number of blade 3 is
Every group of blade number is multiplied by a group number, and according to the size of cutter hub 2, it is 3~4 groups that group number, which selects excellent, and every group of 3 spirality of blade is distributed in knife
In cutter groove on body 2, the blade 3 on each position is provided with the blade of different curves, effective cutting edge, that is, group of one group of blade 3
Synthesize the impeller curve of Roots blower.
Every design parameter and coating of the blade 3 etc., should according to blade material, work piece material, cutter hub knife
The composite factors such as groove design, rationally design and select.The blade 3 uses hard alloy or hard alloy coating, and coating is surface
It is compounded with TiC or TiN.
The cutter hub 2 is made of G35 cast steels or 45 carbon constructional quality steel materials.
The present invention can also use other suitable forms of implementation, such as use the interchangeable tool apron of wedge pressure type high precision and adjustable knot
Structure, makes cutter have the precision of higher.
The basic principle and main feature of the present invention has been shown and described above.It should be understood by those skilled in the art that
The present invention is not limited to the above embodiments, and the above embodiments and description only illustrate the principle of the present invention,
