Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing 1 to 5 is combined,
The utility model is elaborated.It should be noted that illustrated component is not drawn necessarily to scale in the accompanying drawings.This is practical
It is novel to be omitted to known assemblies and well-known technique description, to avoid the utility model is unnecessarily limiting.
It is a kind of to rush overlap cutter, including tool matrix 1 and carbide chip 2 for valve；On the tool matrix 1
Equipped with the first punching 11, the front of the first punching 11 is equipped with counterbore 12, and first punching 11 connects with counterbore 12, described heavy
Carbide chip 2 is equipped in hole 12, the carbide chip 2 is equipped with the second punching 21, second punching 21
It connects with the first punching 11.
The head portion that 4 carries out friction butt welding after clamping with engine valve stem 3, can be formed and be welded in commissure after the completion of butt welding
Tumor overlap 5, the overlap overlap 5 need cutter to remove it.
Traditional common stamping knife compresses after using T-type straight hole to cooperate during the installation process, this kind of positioning method easily causes punching
Knife and workpieces processing decentraction cause product quality abnormal, need multiple shutdown adjustment, and this positioning method is to cutter outer circle ruler
Very little required precision is tighter, and cutter making is more difficult；The appearance profile of tool matrix 1 be frustum structure, the frustum structure with
The male cone (strobilus masculinus) of stamping knife disk 6 is cooperatively connected, and carries out compression positioning by compact heap 7 after connection, positioning is convenient and accurate, concentricity
Good, the angle of frustum structure is 40 degree, and the angle not only can guarantee certain preload force request, but also can guarantee biggish carrying energy
Power.
The counterbore 12 is circular hole, and the diameter of counterbore 12 is 15mm, and the depth of counterbore 12 is 4.5mm, the hard alloy
Blade 2 and counterbore 12 are interference fitted.
First punching 11 is speaker hole, and the external-open angle of speaker hole is 60 degree, convenient for overlap overlap 5 scoriform object to
Outer export.
The diameter of carbide chip 2 be 15mm, carbide chip 2 with a thickness of 4.5mm, the carbide chip
2 are entirely disposed in counterbore 12.
Second punching 21 includes lateral aperture 211 and transitional pore 212, before the lateral aperture 211 is located at transitional pore 212
Portion, the lateral aperture 211 and transitional pore 212 communicate, the transitional pore 212 can seamlessly transit and with 11 phase of the first punching
Logical, the depth of lateral aperture 211 is 2mm, and the depth can not only guarantee that carbide chip 2 had enough cut surfaces, but also energy
It prevents the depth due to lateral aperture 211 excessive, the scoriform object of overlap overlap 5 is caused to be not easy to export.
The material of carbide chip 2 is HT hard alloy, and the hardness range of HT hard alloy is 82HRA-84HRA, institute
The requirement of wear resistance can be reached and prevent from being easy to fragmentation due to excessive high hardness by stating HT hard alloy.
Working principle of the utility model is:
Carbide chip 2 is embedded on tool matrix 1, carbide chip 2 can be used as work when rushing overlap overlap 5
Face solves the problems, such as that common cutter is prone to wear out, and the lateral surface of tool matrix 1 is frustum structure, reaches during the installation process
To self centering purpose, reducing the set-up time, improves installation effectiveness, carbide chip 2 is equipped with the second punching 21,
The front of second punching 21 is lateral aperture 211, and the rear portion of the second punching 21 is transitional pore 212, and lateral aperture 211 can guarantee hard
Alloy blade 2, with certain lateral incision depth, enables the blade of carbide chip 2 to bear bigger in working condition
Cutting force greatly reduces the abrasion of carbide chip, and the first punching 11 on tool matrix 1 is the first speaker hole, can be with
Outside is exported to scoriform object therein is poured, prevents the first punching 11 from blocking.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, on the basis of technical solutions of the utility model, those skilled in the art do not need to pay creativeness
The various modifications or changes that can make of labour it is still within the protection scope of the present utility model.
