Abstract

The utility model discloses a water chamber seal head upsetting-extruding mould, which comprises an upper upsetting-extruding mould and a lower upsetting-extruding mould. On the basis of the use direction, the lower upsetting-extruding mould is a barrel-shaped cylinder body the upper end of which is opened; the inner wall of the lower side of the ,upsetting-extruding mould is provided with a plurality of inward concave grooves; the diameter of the outer side of the upper upsetting-extruding mould is less than that of the inner side of the lower upsetting-extruding mould; and the upper upsetting-extruding mould and the lower upsetting-extruding mould are collinear. The mould leads the water chamber seal head to be molded at one step, does not need subsequent machining, has high efficiency, low cost, compact inner structure and high safety and reliability, and has no defects such as crackles and the like.

Description

Upsetting die of water chamber seaming head
Technical field
The utility model relates to a kind of metal processing mold, particularly a kind of upsetting die of water chamber seaming head.
Background technology
The development of nuclear power has been brought up to first of national strategic aim and the national development ten big support tasks, the autonomy-oriented of the pressure vessel of reactor (production domesticization) has been mentioned unprecedented height in the nuclear power nuclear island, China's Qinshan and Daya Bay nuclear power plant are logical and Nippon Steel import from French avens, cost an arm and a leg.Be the development clean energy resource, reduce the CO2 discharging, China's planning increases by the nuclear power installed capacity of 8,000 ten thousand KW again at the year two thousand twenty, and nuclear power station water chamber head spherical crown exterior material protruding part difficult forming owing to be subjected to the restriction of present free forging process, can only mold the raised material of a monoblock, at last excess stock is machined away, to reach needed forging shape, this method is not only time-consuming but also require great effort, and cost is extremely expensive.
The utility model content
In order to remedy above deficiency, the utility model provides a kind of upsetting die of water chamber seaming head, and the water chamber head of this upsetting die of water chamber seaming head production once forms, and need not the follow-up loaded down with trivial details processing of carrying out again, defective, its reliability and intensity height such as water chamber head compact structure flawless.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of upsetting die of water chamber seaming head, comprise upsetting squeeze patrix and upsetting squeeze counterdie, to use direction to be benchmark, the upsetting squeeze counterdie is the tubbiness cylinder of upper end open, upsetting squeeze counterdie downside inwall is provided with the groove of some indents, upsetting squeeze patrix outside diameter is less than upsetting squeeze counterdie inside diameter, upsetting squeeze patrix and upsetting squeeze counterdie center conllinear, steel ingot in the upsetting squeeze counterdie by after the upsetting squeeze patrix extruding, just a part of the flowing downward of metal enters in the groove of upsetting squeeze counterdie downside inwall, so just begun to take shape the projection on the water chamber head lateral wall, part metal upwards flows along the gap between upsetting squeeze counterdie and the upsetting squeeze patrix and just forms an indent die cavity, just begins to take shape water chamber head drum part.
Useful technique effect of the present utility model is: the utility model with the steel ingot fixed placement of high temperature heating in the upsetting squeeze counterdie of sealing, the upsetting squeeze patrix carries out upsetting squeeze to steel ingot, metal part in the upsetting squeeze counterdie is flowed downward form the outside projection of water chamber head, another part metal upwards flows and forms the drum part of water chamber head, the water chamber head one-shot forming is come out, need not follow-up loaded down with trivial details processing, thereby defective, reliability and intensity height such as efficient height, cost are low, the fine and close flawless of its internal structure.

The specific embodiment
Embodiment: a kind of upsetting die of water chamber seaming head, comprise upsetting squeeze patrix 2 and upsetting squeeze counterdie 3, to use direction to be benchmark, upsetting squeeze counterdie 3 is the tubbiness cylinder of upper end open, upsetting squeeze counterdie 3 downside inwalls are provided with the groove 31 of some indents, upsetting squeeze patrix 2 outside diameter are less than upsetting squeeze counterdie 3 inside diameter, upsetting squeeze patrix 2 and upsetting squeeze counterdie 3 center conllinear, steel ingot in upsetting squeeze counterdie 3 by after upsetting squeeze patrix 2 extruding, just a part of the flowing downward of metal enters in the groove 31 of upsetting squeeze counterdie 3 downside inwalls, so just begun to take shape the projection on the water chamber head lateral wall, part metal upwards flows along the gap between upsetting squeeze counterdie 3 and the upsetting squeeze patrix 2 and just forms an indent die cavity, just begins to take shape water chamber head drum part.
