Cycle etc. has important influence to the production efficiency and production cost of material.
The structure of current mould of swaging, material, production and processing are substantially using traditional pattern, there is mould structure not
Use up reasonable, process-cycle length, less efficient, cost is high, service life is short, dimensional accuracy is relatively low, rough surface is poor, high-performance
The problems such as performance of mold materials does not give full play to, mold materials waste many.
The content of the invention
The technical problems to be solved by the invention are to use there is provided a kind of swager for above-mentioned the deficiencies in the prior art
Mould.The mould structure is simple, and one layer of overlay cladding is provided with the inwall of die hole, and overlay cladding uses high performance mould system
Producing material stockpile welds to be formed, and the overlay cladding has the characteristics such as high intensity, high tenacity, high antifatigue and high abrasion, adds mould
The performance of swaging of hole inner working face, the mould structure that solves existing swager is unreasonable, performance is low, cost is high, efficiency
The problems such as low, low precision, swager mold use performance is improved, shortens the manufacturing cycle of swaging, reduce the expensive mould of high-performance
Have the consumption of material, significantly reduce manufacturing cost.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of swager mould, including mould master
Body, the die main body is along the circumferential direction assembled successively by multiple mold blocks, and the mold block includes supporter and work
Body, the working body assembly of each mold block forms the workspace of the die main body, the workspace of the die main body
Center position offers die hole, it is characterised in that overlay cladding is provided with the inwall of the die hole, the overlay cladding
Inner surface is that swager is used for the working face of swaging tool, and the material of the overlay cladding is cobalt-chromium-tungsten alloy or vitallium；
The die hole is manhole, and the both sides port of the die hole outwards expands and is conical structure.
Above-mentioned a kind of swager mould, it is characterised in that the material of the supporter is hard alloy；The work
The material of body is identical with the material of working body with the material of supporter or the material of the overlay cladding.
Above-mentioned a kind of swager mould, it is characterised in that the thickness of the overlay cladding is 0.01mm~100mm.
Above-mentioned a kind of swager mould, it is characterised in that the roughness of the overlay cladding is 0.1mm~20mm.
