Description
Technical field
It the utility model is related to CEMENTED CARBIDE PRODUCTION manufacturing field, and in particular to a kind of mould for producing hard alloy columnar teeth
Tool.
Background technology
In CEMENTED CARBIDE PRODUCTION manufacture, hard alloy alloy column tooth is one of major class product.It presses supporting brill
Head Type division, mainly there is the several leading major class of rock drill bit, down-the-hold drill bit, rotary drill；Divided by alloy odontoid, mainly there is ball-type
Tooth, tapered teeth, bullet type tooth, chisel teeth, scoop chisel insert, tack tooth etc..
Conventional alloys tooth is made up of 103 3 crown 101, tooth body 102, bottom of the tooth parts, and its basic structure is as shown in Figure 1.
In the prior art, traditional dies when producing alloy column tooth are as shown in Fig. 2 by 3 groups of former 1, upper punching 2 and undershoot
Into mould molding chamber is arranged in punching 2 and undershoot 3, and former 3 is only a cylindrical tube.When the height h of carbide button crown 101 compared with
Long, when the inclination alpha of crown 101 is smaller, it is very sharp to will result in the die cavity position of undershoot 3, during compacting, due to stress concentration at this, pressure
Base easily cracks（The position of crackle 14 is as shown in Figure 3）, and because the chamfering of undershoot 3 is excessively sharp, the also rapid wear of undershoot 3
It is bad.
The content of the invention
The purpose of this utility model is to provide a kind of production hard alloy columnar teeth mould, solves prior art and easily presses
Checking line and the flimsy problem of undershoot.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：One kind production hard alloy columnar teeth mould,
Including former, upper punching and undershoot, it is described on rush on end the shaping cavity of the bottom of the tooth that corresponding hard alloy columnar teeth is set；It is described
Former is divided axially into three sections along it：First paragraph, second segment and the 3rd section, the first paragraph, second segment and the 3rd section are mutually solid
Fixed connection；The endoporus of the first paragraph is with above punching through the cylindrical hole into cooperation, and described 3rd section of endoporus is to be punched through with
Enter the cylindrical hole of cooperation, and the endoporus of the second segment is the forming hole of the crown outer peripheral portion of corresponding hard alloy columnar teeth；
The shaping cavity of the tip portion of the crown of corresponding hard alloy columnar teeth is set on the undershoot end.
In such scheme, the first paragraph, second segment and the 3rd intersegmental are fixedly connected by brazing mode.
Utility model works principle and advantage are as follows：
The part design of carbide button crown profiled section on the second segment of former, is made undershoot profiled section high by the utility model
Degree reduces, and reduces the stress concentration caused by undershoot is excessively sharp, and lowers the risk for producing pressed compact crackle, while make undershoot again
It is hardly damaged.Former is divided into three sections by the utility model, and main purpose is as follows：One is easy for Mold Making；Second, as run into phase
With the carbide button of diameter, the first paragraph of its former, the 3rd section can only change second segment with public, production cost can be reduced.

In the figures above：1st, former；11st, first paragraph；12nd, second segment；13rd, the 3rd section；2nd, upper punching；21st, it is molded cavity；3、
Undershoot；31st, it is molded cavity；101st, crown；102nd, tooth body；103rd, bottom of the tooth；104th, crackle.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment：Referring to shown in Fig. 1, Fig. 4：
One kind production hard alloy columnar teeth mould, including former 1, upper punching 2 and undershoot 3, the upper punching are set on 2 ends
Put the shaping cavity 21 of the bottom of the tooth 103 of corresponding hard alloy columnar teeth.
Referring to shown in Fig. 1, Fig. 4, the former 1 is divided axially into three sections along it：First paragraph 11, second segment 12 and the 3rd section
13, the first paragraph 11, second segment 12 and the 3rd section 13 are mutually permanently connected.The endoporus of the first paragraph 11 is to be worn with upper punching 2
Enter the cylindrical hole of cooperation, described 3rd section 13 of endoporus is the cylindrical hole that cooperation is penetrated with undershoot 3, and the second segment 12
Endoporus be corresponding hard alloy columnar teeth the outer peripheral portion of crown 101 forming hole；Corresponding hard is set on the end of undershoot 3
The shaping cavity 31 of the tip portion of the crown 101 of alloy column tooth.
It is fixedly connected between the first paragraph 11, second segment 12 and the 3rd section 13 particular by brazing mode.In practice
Certainly fixed solution, such as bolt connection etc. can also be used.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
It is interior.
