Abstract
The utility model provides a hard alloy road breaking tooth constitutes its characterized in that by work portion (1) and weld part (2): work portion (1) at the bottom of by prong (11), tooth middle section (12) and tooth (13) constitute, prong (11) are conical, and tooth middle section (12) are cylindrical, and (13) are dug way tooth axis rotation by a circular arc wire -wound to form at the bottom of the tooth, weld part (2) comprise one toper section (21) and a chamfer portion (22), (13) are connected at the bottom of the tip of toper section (21) and the tooth of work portion (1), and chamfer portion (22) is connected to main aspects, and the cone angle of toper section (21) is 0.5 to 5. The utility model provides the high qualification rate of product, reduction in production cost, and on the basis that baseplane (even stress surface of time spent) area is unchangeable of its the chamfer portion of way tooth of digging after improving, still increased circumference welded area, promoted the welding effect.
Description
Technical field
This utility model is related to a kind of hard alloy road breaking tooth.
Background technology
Hard alloy road breaking tooth is using metallurgical forming method direct pressing molding.Existing hard alloy road breaking tooth be by
Work department and weld part are constituted, and its weld part is one section of small column, the end-beveling of small column.Because its weld part is vertical
The face of cylinder, is unfavorable for the demoulding, and mould is easily damaged, and is unfavorable for the flowing of welding fluid during welding, is also easy to produce rosin joint.
The content of the invention
The purpose of this utility model is to provide a kind of hard alloy road breaking tooth, is easy to take off on the premise of performance is ensured
Film, lowers manufacture difficulty, improves the qualification rate of product.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of hard alloy road breaking tooth, by work department
Constitute with weld part, the work department is made up of crown, tooth stage casing and bottom of the tooth, the crown is cone, tooth stage casing is circle
Cylindricality, bottom of the tooth is formed around the rotation of road breaking tooth axis by a circular arc line；The weld part is made up of a conical section and a chamfered section,
The small end of the conical section is connected with the bottom of the tooth of work department, big end connection chamfered section；And the cone angle of the conical section is 0.5 °
To 5 °.
In such scheme, height of the weld part on road breaking tooth axial direction is 1 mm to 1.5mm.
In such scheme, the chamfered section baseplane of the weld part is provided with three salient points.
Utility model works principle and advantage are as follows：
The weld part of prior art cylindrical shape is changed to conical section by this utility model, and the former for making mould has carried the demoulding
Angle, so as to be hardly damaged upper punch, improves the qualification rate of product, reduces production cost, and road breaking tooth its chamfering after improving
The baseplane in portion（Even if the stress surface of used time）On the basis of area is constant, the area of circumferential welding is also add, improve weldering
Connect effect.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to this utility model：
Embodiment：Referring to shown in accompanying drawing 1～2：
A kind of hard alloy road breaking tooth, is made up of work department 1 and weld part 2, and the work department 1 is by crown 11, tooth stage casing
12 and bottom of the tooth 13 constitute, the crown 11 for cone, tooth stage casing 12 for cylinder, bottom of the tooth 13 is around road breaking by a circular arc line
The rotation of tooth axis is formed；The weld part 2 is made up of a conical section 21 and a chamfered section 22, the small end and work of the conical section 21
The bottom of the tooth 13 for making portion 1 connects, big end connection chamfered section 22；And the cone angle of the conical section 21 is 0.5 ° to 5 °.
Height of the weld part 2 on road breaking tooth axial direction is 1 mm to 1.5mm.
The baseplane of chamfered section 22 of the weld part 2 is provided with three salient points 23.
The weld part of prior art cylindrical shape is changed to conical section 21 by this utility model, and the former for making mould has carried the demoulding
Angle, so as to be hardly damaged upper punch, improves the qualification rate of product, reduces production cost, and road breaking tooth its chamfering after improving
The baseplane in portion（Even if the stress surface of used time）On the basis of area is constant, the area of circumferential welding is also add, improve weldering
Connect effect.
Above-described embodiment only to illustrate technology design of the present utility model and feature, its object is to allow and be familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalence changes made according to this utility model spirit or modification, all should cover protection domain of the present utility model it
It is interior.
