Abstract
The utility model belongs to mechanical machining tool and proposes a double positive rake angle indexable vertically installed hard alloy milling cutter, which is composed of a cutter head 1 and a plurality of blades 2, wherein a plurality of blade slots are evenly distributed on the ex-circle surface of a frustum on the lowest portion of the cutter head, the sharp angle of a diamond blade is 80 degrees, the included angle between two main cutting surfaces and a normal surface of the blade top surface is 10 degrees, the blade 2 is a diamond shape, the 80-degree angle of the blade and the 3-degree included angle formed by the blade slot top surface and the cutter head lower end surface form a 7-degree axial rake angle of the blade, a 10-degree included angle of the two main cutting surfaces of the blade and the normal surface of the blade top surface and the 10-degree angle between the blade slot bottom surface and a tangent of the blade edge form a blade 0-degree radial rake angle, thereby forming the double positive rake angle by the blade. The double positive rake angle indexable vertically installed hard alloy milling cutter has rational design and simple structure, and provides demanded positive rake angle cutters for highly effective rough milling of vertically installed indexable milling cutters for manufacturing low carbon steel or medium carbon steel products.
Description
Technical field
The utility model belongs to machining tool, mainly proposes a kind of pair of indexable upright dress carbide-tipped milling cutter of positive rake angle, is used for mild steel or medium carbon steel Milling Process.
Background technology
Gradually adopt the indexable milling cutter of the upright dress of blade (insert tangential arrangement) mounting means in recent years both at home and abroad, its feature is: 1. insert tangential is arranged, and it is big that blade itself bears the cross section of cutting force; 2. blade adopts a screw to be fixed on the cutter hub, and is simple in structure, chip pocket is big, and chip removal is unobstructed; 3. the blade back allows the worn area of broad, and adjacent knife blades is difficult for tipping and damage; 4. structure is very simple, need not other clamp fitting.It is applicable to the roughing of the big cutting output of processing cast iron, cast steel and weldment.Because the blade of upright dress cutter all is a rectangle blade with holes, when tangentially being contained on the insert groove of cutter hub, just form two negative rakes.The product of processing mild steel or medium carbon steel and so on must have positive (or 0 °) radial rake.Like this, how on upright dress indexable milling cutter, realize that positive radial rake has just become the key issue of efficiently rough milling processing of mild steel or medium carbon steel series products.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of pair of indexable upright dress carbide-tipped milling cutter of positive rake angle, efficiently rough mills existing problem in the processing to solve mild steel or medium carbon steel,
The utility model is finished the technical scheme that its invention task can take: a kind of pair of indexable upright dress carbide-tipped milling cutter of positive rake angle, and it mainly is made of cutterhead and a plurality of blade; Cutterhead is made of two frustums of superposed round platform and bottom, the uniform a plurality of semicircle chip areas of the periphery of foot frustum, and corresponding each chip area has insert groove and insert groove is communicated with chip area; The insert groove end face forms 3 ° angle to pairing chip area direction inclination and with the cutterhead lower surface, insert groove bottom surface and the angle between the tangent line of its blade of insert groove inner blade are 10 °, and the angle between the insert groove inwall bottom surface that insert groove bottom surface and blade main cutting face are fitted is 100 °; Blade is a rhombus, the acute angle of blade is 80 °, two main cutting face is 10 ° with the angle of the normal plane of blade end face, 3 ° of angles that 80 ° of angles of diamond shaped insert and above-mentioned insert groove end face and cutterhead lower surface form constitute 7 ° of axial rakes of blade jointly, and 10 ° of angles between the 10 ° of angles of the normal plane of two main cutting faces of described blade and blade end face and the tangent line of insert groove bottom surface and knife-blade constitute the radial rake of 0 ° on blade jointly.
The utility model is reasonable in design, and is simple in structure, and the processing of efficiently rough milling of processing mild steel or medium carbon steel series products for upright dress indexable milling cutter provides needed positive rake angle cutter.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1.
Among the figure, 1, cutterhead, 2, diamond shaped insert, 3, the plum blossom screw, 4, insert groove, 5, chip area.
The specific embodiment
The embodiment that provides with reference to the accompanying drawings is illustrated the utility model structure:
As shown in Figure 1, 2, the utility model mainly is made of cutterhead 1 and a plurality of blade 2; Cutterhead 1 is made of two frustums of superposed round platform and bottom, the uniform a plurality of semicircle chip areas 5 of the periphery of foot frustum, and corresponding each chip area has insert groove 4 and insert groove 4 is communicated with chip area 5; The insert groove end face forms 3 ° angle to pairing chip area direction inclination and with the cutterhead lower surface, its upper end of one of them internal face of insert groove 4 has 10 ° chamfering, satisfying the needs that diamond shaped insert is installed, described internal face be positioned at the far-end of corresponding chip area.Insert groove bottom surface and the angle between the tangent line of its blade of insert groove inner blade are 10 °, and the angle between the insert groove inwall bottom surface that insert groove bottom surface and blade main cutting face are fitted is 100 °; Blade is a rhombus, the acute angle of blade is 80 °, two main cutting face is 10 ° with the angle of the normal plane of blade end face, 3 ° of angles that its 80 ° of angles and above-mentioned insert groove end face and cutterhead lower surface form have constituted 7 ° of axial rakes of blade jointly, 10 ° of angles between the 10 ° of angles of the normal plane of described two main cutting faces and blade end face and the tangent line of insert groove bottom surface and knife-blade have constituted the radial rake of 0 ° on blade jointly, are two positive rake angles thereby make blade.
