Abstract

The utility model belongs to a mechanical machining tool, in particular to a dihedral disk-type milling cutter for honeycomb materials. The cutter comprises a cutter handle, a scrap cutting disk, and a cutter blade. The scrap cutting disk is in the shape of a cone; the bottom surface of the outer edge of the disk surface of the cutter blade and a rotating shaft of the cutter forms an angle which is more than 90 degrees but less than or equal to 135 degrees; the bottom surface of the scrap cutting disk is in fit with the upper surface of the disk surface of the cutter blade, as well as the upper surface of the cutter blade; the diameter of the scrap cutting disk is smaller than that of the cutter blade by 2 mm. In the utility model, the edge of the cutter blade is fabricated to have a dihedral angle, thereby enabling the included angle between the cutter edge and the rotating shaft of the cutter to be obtuse; the cutter edge of the cutter blade is in organic fit with the scrap cutting disk, so that the honeycomb cracking can not happen when the cutter cuts honeycomb composite materials with large curvature, and the quality of cutting honeycomb composite materials with large curvature is improved. In addition, the dihedral angle Alpha of an upper edge of the cutter blade can be divided into a plurality of series according to the difference in the curvature of spare parts to be cut, that is, the larger the curvature of spare parts is, the bigger the chosen angle Alpha is, and the dihedral angle Alpha of the cutter can be chosen in the range of 90 degrees to 135 degrees.

Description

Upper counterangle disc type honeycomb milling cutter

Technical field

The utility model belongs to machining tool, relates to a kind of upper counterangle disc type honeycomb milling cutter.

Background technology

The structure of existing honeycomb disc type milling cutter is made up of blade and chip dish and handle of a knife substantially, the outer most edge of blade is a blade, the lower surface of blade and tool rotating shaft wire clamp angle are 90 °, the blade of the upper surface of blade and the rotating shaft of cutter have a downward slightly drift angle, (see Fig. 1, α=90 ° or be slightly less than 90 °) blade forms a closed circular and vertical with the tool rotating shaft line.The chip dish is a cylinder, and the lower plane of the upper surface of blade and chip dish is fitted, and the lower plane of considering broken dish to be worth doing is vertical with the rotation of cutter.Utilize the disc type Tool in Cutting cellular composite material of this kind structure, when cutter when doing the direction vertical motion cutting with the tool rotating shaft line, cutting effect is better.So this kind cutter is fit to processing plane and milder hyperboloid and the bigger single-curvature convex surface of curvature.But this kind cutter then can occur processing the problem that drag greatly, easily causes honeycomb to tear during than the deep camber concave surface in processing, when curvature during greatly to certain value this kind disc type cutter then can't process.

Summary of the invention

The purpose of this utility model provides a kind of upper counterangle disc type honeycomb milling cutter that can process deep camber concave surface cellular material.

Technical solution of the present utility model is, cutter comprises handle of a knife, the broken dish of bits and blade, considering broken dish to be worth doing is cone, the blade bottom surface of blade card outer rim and the angle of tool rotating shaft be＞and 90 °～≤ 135 °, consider the bottom surface of broken dish and the upper surface of blade card and the upper surface of blade to be worth doing and match, consider the diameter 2mm of the diameter of the broken face of trying to get to the heart of a matter to be worth doing less than blade.Advantage that the utlity model has and beneficial effect, the utility model is changed the structure of blade inverted diherdral in the past, with the blade of blade to the upper counterangle, the angle α that makes blade and tool rotating shaft in obtuse angle, the blade of blade makes cutter can not cause honeycomb to tear when cutting deep camber concave surface cellular composite material with the combination of the broken dish of bits, has improved the cutting quality of deep camber concave surface cellular composite material.The dihedral α of the utility model blade upper knife edge can be divided into some series according to the difference that is cut the part amount of curvature, and the big more α angle of selecting for use of part curvature is also big more, and the dihedral α angle of cutter can be selected in 90 °～135 ° scopes.

Description of drawings

Fig. 1 is the utility model prior art structural representation;

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing cutter is further described, referring to accompanying drawing 2, cutter comprises handle of a knife 1, the broken dish 2 of bits and blade 3, consider broken dish 2 to be worth doing and be cone, blade 5 bottom surfaces of blade card 4 outer rims and the angle α of tool rotating shaft be＞and 90 °～≤ 135 °, the selection of α angle can be decided according to the curvature that is cut part, and the curvature that is cut part is big more, and the α angle is big more; Considering the bottom surface of broken dish 2 and the upper surface of blade card 4 and the upper surface of blade 5 to be worth doing matches, consider the diameter 2mm of the diameter of broken dish 2 bottom surfaces to be worth doing less than blade 3, it is fixing with blade 3 usefulness screws 6 to consider broken dish 2 to be worth doing, the bottom surface of considering broken dish 2 to be worth doing is corresponding with the dihedral of blade 3 upper knife edges 5, blade 3 is fitted with the broken dish 2 of bits all the time, and blade 5 cylindricals are greater than the broken dish of bits 2 end cylindrical 2mm.

Claims

1. upper counterangle disc type honeycomb milling cutter, comprise handle of a knife (1), consider broken dish (2) and blade (3) to be worth doing, it is characterized in that, consider broken dish (2) to be worth doing and be cone, blade (5) bottom surface of blade card (4) outer rim and the angle of tool rotating shaft be＞and 90 °～≤ 135 °, consider the bottom surface of broken dish (2) and the upper surface of blade card (4) and the upper surface of blade (5) to be worth doing and match, consider the diameter 2mm of the diameter of broken dish (2) bottom surface to be worth doing less than blade (3).
