Abstract
The utility model belongs to mechanical machining tools and proposes a hard alloy indexable rail top slope cutting cutter, which is composed of a round cutter head 1 and a plurality of blade groups 2, wherein the cutter head 1 is composed of two round discs with different diameters, the lower disc surface of the cutter head 1 is a rotary surface which is matched with the shape of the railroad rail top surface, a plurality of blade groups 2 which are evenly distributed along the circumference of the cutter head are arranged on the lower disc surface of the cutter head 1, blades of each blade group are arranged radially on the lower disc surface of the cutter head, and the blades of a neighboring blade group on the lower disc surface are arranged in a staggered mode along the circumference direction of the blades. Each blade of the blade group 2 is provided with different R contour lines for adapting the manufacture of railroad rail top shapes. The blades are fixed in blade slots through plum blossom screws 3. The blades of the hard alloy indexable rail top slot cutting cutter are arranged along the tangential direction and namely adopting a vertical installation mode, and the cross section of the blades for bearing the cutting force is big and can bear big cutting force and impact force, can adapt machine tool with high power, and can fully improve the production efficiency.
Description
Technical field
The utility model belongs to the track process tool, mainly proposes a kind of hard alloy rotatable tread slope milling cutter, is used for the track Milling Process of railroad curve or lane change place.
Background technology
The standard track of track is rolled into by ordinary steel, and only the track in railroad curve or lane change place needs machine-shaping; In the past, the manufacturer of this track all processes with planer, because moulding section is made up of circular arc and each angle faces, make planing operation low precision, efficient low, Lip river, Luoyang hard worker's modulus control Co., Ltd is designed to carbide alloy paperback indexable milling cutter according to customer requirements, be used for the acclerating road switch processing and forming, make working (machining) efficiency improve several times; But find that through application in practice also there is following problems in existing cutter: during carbide alloy paperback indexable milling cutter processing potassium steel, the lathe vibrations are big, and working (machining) efficiency is low, and blade is fragile; And accessory is many, changes complicated.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of hard alloy rotatable tread slope milling cutter, above shortcomings when processing potassium steel to solve existing track profile milling cutter.
This practicality novel finished the technical scheme that its invention task takes: a kind of hard alloy rotatable tread slope milling cutter is made of circular beater plate and a plurality of set of blades; Described cutterhead is made of the disk of two different-diameters, card is the surface of revolution that coincide with track end face shape under the cutterhead, a plurality of set of blades along its circumference uniform distribution are set on the following card of cutterhead, the arranged radially on the following card of cutterhead of the blade of each set of blades, the blade that is positioned at adjacent knife blades group on the following card along the circumferential direction is staggered.
Each blade of described set of blades has the outline line of different R, in order to adapt with processing track tread shape.
Described blade is fixed in the insert groove by the plum blossom screw.
Blade of the present utility model adopts the mounting means of upright dress, and it is big that blade bears the cross section of cutting force, can bear big cutting force and impulsive force, and accessory is few, and blade directly is fixed on screw in the cutter groove of dead location, need not adjust to guarantee for a long time that precision is constant.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Among the figure: 1, cutterhead, 2, set of blades, 3, the plum blossom screw, 4, chip area, 5, insert groove.
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 is made of circular beater plate 1 and a plurality of set of blades 2; Cutterhead 1 is made of the disk of two different-diameters, the surface of revolution that card is and track end face shape is coincide under it, a plurality of set of blades 2 along the cutterhead circumference uniform distribution are set on the following card of cutterhead, the arranged radially on the following card of cutterhead of the blade of each set of blades, the blade that is positioned at adjacent knife blades group on the following card along the circumferential direction is staggered.
On the following card of cutterhead 1, have the insert groove 5 of many groups along cutterhead 1 circumference uniform distribution, every group of insert groove is in the card upper edge arranged radially of the bottom of cutterhead, be positioned at that adjacent not on the same group insert groove 5 along the circumferential direction is staggered on the following card, each blade of set of blades 2 all is fixed in the insert groove 5 by plum blossom screw 3; Each blade of set of blades has the outline line of different R, in order to adapt with processing track tread shape.
