Abstract
The utility model relates to a polygon welding blade, which belongs to the technical field of processing tools. The polygon welding blade comprises a polygon structured blade basal body and a superhard cutting head which is welded on a sharp corner of the blade basal body, wherein a positioning platform which is lower than the end surface of the blade basal body is arranged on a position of the sharp corner of the blade basal body close to the end surface of the blade basal body, an overhanging arm which extends to the middle portion of the positioning platform toward the tip direction of the sharp corner of the blade basal body is arranged on the end surface of the blade basal body, a slot which is inserted with the superhard cutting head is formed on a position between the overhanging arm and the positioning platform, and the superhard cutting head is welded in ten slot. The slot is formed on the position between the overhanging arm on the blade basal body and the positioning platform, the superhard cutting head is welded in the slot when a blade is made, the contact area of the superhard cutting head and the blade basal body can be inserted through the structure of the slot, the welding area between the superhard cutting head and the blade basal body is increased, and the superhard cutting head is firmly welded.
Description
Technical field
The utility model relates to a kind of polygon welding blade, belongs to the process tool technical field.
Background technology
Welding blade of the prior art is generally the equilateral or unequal-sided polygonized structures such as rhombus, square, triangle, and welding blade is that the cutter head of being made by blade base and superhard material forms.Notification number is that the Chinese utility model patent that CN202461560U, name are called " a kind of braze welding type polygon compounded superhard blade " discloses a kind of polygon superhard cutting blade, this blade comprises polygonal matrix, offer groove on matrix, be welded with super-hard cutter bits in groove.Because the contact area of the cutter head of this blade and matrix is little, cause not prison welding to be leaned on, during use, blade is easy to come off from matrix.
Summary of the invention
The polygon welding blade that provides a kind of cutter head to be not easy to come off from matrix is provided the purpose of this utility model.
For achieving the above object, the utility model adopts following technical scheme: a kind of polygon welding blade, the blade base and the super-hard cutter bits that is welded on the blade base sharp corner that comprise polygonized structure, the sharp corner of described blade base is provided with the locating platform lower than this end face near the position of blade base end face, described blade base end face has the cantilevered leg that extends to the locating platform middle part to the tip direction of blade base wedge angle, position between this cantilevered leg and locating platform forms the slot inserted for described super-hard cutter bits, described super-hard cutter bits is welded in slot.
The pointed shape structure of the front end of described cantilevered leg for protruding.
The described blade base structure that assumes diamond in shape.
Described blade base is the equilateral triangle structure.
Cantilevered leg on blade base of the present utility model and the position between locating platform form slot, while making blade, cutter head is welded in slot, inserting slot construction can make the contact area of cutter head and blade base increase, thereby strengthened the bonding area between cutter head and blade base, made the cutter head welding more firm.
The front end of cantilevered leg is that outstanding pointed shape structure can make the bonding area of cutter head and blade further strengthen, thereby further increases the weld strength of cutter head.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment 2;
Fig. 4 is the upward view of Fig. 3.
The specific embodiment
The structure of the utility model embodiment 1 as depicted in figs. 1 and 2, the polygon welding blade of the present embodiment is diamond shaped insert, it comprises the blade base 1 assumed diamond in shape and the super-hard cutter bits 2 that is welded on blade base 1 sharp corner, the sharp corner of blade base 1 is provided with the locating platform lower than the blade base end face near the position of blade base end face, the blade base end face has the cantilevered leg that extends to the locating platform middle part to the tip direction of blade base wedge angle, position between this cantilevered leg and locating platform forms the slot inserted for super-hard cutter bits 2, super-hard cutter bits 2 is welded in slot, the pointed shape structure of the front end of cantilevered leg for protruding.The sharp corner of the blade base of the present embodiment is equipped with locating platform near the position of upper and lower two end faces of blade base, on the upper and lower end face of blade base, all has cantilevered leg, each cantilevered leg respectively with corresponding locating platform between position form slot.
The slot of the present embodiment can make the bonding area of cutter head and blade base increase, thus being welded on blade base of making that cutter head can be more firm.
As shown in Figure 3 and Figure 4, as different from Example 1, the welding blade of the present embodiment is equilateral triangle to the structure of the utility model embodiment 2, on each wedge angle of the blade base of equilateral triangle structure, all is welded with super-hard cutter bits.
In other embodiment of the present utility model, when welding blade be shaped as square or rule or during irregular polygonized structure, corresponding, blade base also should be square or rule or irregular polygonized structure.
In other embodiment of the present utility model, also can be only at the sharp corner of blade base, near the position of one of them end face of blade base, locating platform be set, only on this end face, cantilevered leg is set.
In other embodiment of the present utility model, the front end of cantilevered leg can be also the arc-shaped structure protruded.
Claims (4)
1. a polygon welding blade, the blade base and the super-hard cutter bits that is welded on the blade base sharp corner that comprise polygonized structure, it is characterized in that: the sharp corner of described blade base is provided with the locating platform lower than this end face near the position of blade base end face, described blade base end face has the cantilevered leg that extends to the locating platform middle part to the tip direction of blade base wedge angle, position between this cantilevered leg and locating platform forms the slot inserted for described super-hard cutter bits, and described super-hard cutter bits is welded in slot.
