Abstract
The present invention relates to a kind of coal plough for underground coal mine thin seam mining, specifically a kind of shaping tool for coal plough.Existing shaping tool in coal mining process, run into that ature of coal hardness is high, the haircut of rank, coal seam when educating incomplete geological conditions shaping tool can bear very large impact load, cause alloy cutter head welding position to snap, cause cutter head to come off.The present invention is made up of cutter hub and alloy cutter head, and the cutter groove of alloy cutter head is the dovetail type hook groove tiltedly opened, and hook groove bottom is parallel with cutter hub front end face, and hook groove side is parallel with cutter hub upper surface; Alloy cutter head is ridge type structure, and alloy cutter head is front wide and rear narrow shape, and alloy cutter head two sides are wedge shape, angle of wedge C
2it is 3 ~ 7 °; Cutter hub upper surface is provided with cylindrical hole, and column type alloy cutter head is embedded in the cylindrical hole of cutter hub upper surface.Structure of the present invention makes the contact area of alloy cutter head and cutter hub increase, and improves the stressing conditions of alloy cutter head soldering place, reduces cutter head and come off.
Description
Technical field
The present invention relates to the technical field of coal plough for underground coal mine thin seam mining, specifically a kind of shaping tool for coal plough.
Background technology
The existing coal plough cutter for underground coal mine exploitation is in the process of mining, particularly run into that ature of coal hardness is high, the haircut of rank, coal seam is when educating incomplete geological conditions, shaping tool can bear very large impact load, causes alloy cutter head welding position to snap, repeated stock, the alloy cutter head in cutter and cutter hub is very easily caused to depart from, make tool failure, and due to girdle narrow space, maintenance operation difficulty, cause downtime long, affect the production efficiency of girdle.
Summary of the invention
The object of the invention is to want to provide a kind of shaping tool for coal plough, to solve shaping tool, the cutter head occurred in rib process comes off, the problem such as cracked cutting, especially the problem that comes off of cutter head.
The technical solution used in the present invention is: comprise shaping tool by cutter hub and alloy cutter head, column type alloy cutter head; Alloy cutter head to be embedded in the cutter groove of cutter hub and to weld together, and cutter hub lower end is inserted in shaping tool seat, and cutter hub penetrates square groove by screw and is fixed on shaping tool seat by cutter hub; It is characterized in that: the alloy cutter head cutter groove on cutter hub is the dovetail type hook groove tiltedly opened, and hook groove bottom is parallel with cutter hub front end face M, and hook groove side is parallel with cutter hub upper surface N, hook groove bottom and side angle α are 60 ~ 80 °; Alloy cutter head upper surface is crossed by a face and b face and forms the symmetrical expression ridge structure that centre is high, both sides are low, the angle C of a face and b face and horizontal plane
1it is 5 ~ 20 °; Alloy cutter head is front wide and rear narrow shape, and two sides are wedge shape, angle of wedge C
2it is 3 ~ 7 °;
Cutter hub upper surface N is provided with cylindrical hole, and column type alloy cutter head embeds in cylindrical hole, is fixed by copper base brazing, and the point of a knife of column type alloy cutter head is L to the distance of upper surface N
1.
Further, the point of a knife of the column type alloy cutter head 2 on the cutter hub 1 of coal planer planning cutting knife tool is 2 ~ 5mm to the distance L1 of upper surface N.
Advantage of the present invention is: after cutter hub adopts the dovetail type hook groove structure tiltedly opened, the contact area of alloy cutter head and shaping tool cutter hub increases, improve the stressing conditions of alloy cutter head soldering place, larger compressive stress, shear stress and impact load can be born in working angles, reduce cutter head and come off.Column type alloy cutter head is embedded in cutter hub upper surface, protects the upper surface of cutter hub.This cutter forms with simple structure, stable structure form, lower financial cost add cutting-tool's used life.

1it is 5 ~ 20 °; Alloy cutter head 3 is front wide and rear narrow shape, and two sides are wedge shape, angle of wedge C
2it is 3 ~ 7 °;
Cutter hub 1 upper surface N is provided with cylindrical hole, and column type alloy cutter head 2 embeds in cylindrical hole, is fixed by copper base brazing, and the point of a knife of column type alloy cutter head 2 is L to the distance of upper surface N
1.
The point of a knife of the column type alloy cutter head 2 on the cutter hub 1 of coal planer planning cutting knife tool is L1 to the distance of upper surface N is 2 ~ 5mm.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to technical scheme of the present invention the apparent change of extending out or variation be still in the row of protection scope of the present invention.
