Abstract
The utility model provides a die for manufacturing a flow guide coaming for members in a nuclear power reactor. The die comprises an indentation cavity, a mandrel, a core roller, a broaching cavity, a washer and a locking nut. The indentation cavity is sleeved on the mandrel to form an indentation cavity combination die, and the broaching cavity is sleeved on the mandrel to form a broaching and ring milling cavity combination die. Forging fiber directions of the flow guide coaming produced by the two groups of dies are in followed distribution, and the die is small in machining allowance, higher in mechanical property and longer in service life, resistant to high temperature, high pressure and corrosion, and low in cost.
Description
Technical field
The utility model belongs to forging and stamping manufacturing technology field, particularly a kind of mould of manufacturing nuclear in-pile component flow skirt.
Background technology
Flow skirt, is a kind of special-shaped circular piece that has inner convex platform, and its classical production process generally adopts to forge and makes, then on ring rolls, roll out the annular element of square-section or adopt to forge sheet material, and by bending to ring, then by its two ends welding fabrication.
The flow skirt that at present adopts forging mode to manufacture, because its inner convex platform machine direction is cut off, has not only reduced its combination property and service life, and because machine-finish allowance causes greatly the waste of material.The rectangular base that adopts forging, because of its body weight, wall thickness, large in bending time difficulty, production cost is high.Two kinds of methods of described this because of machine-finish allowance large, waste of material is serious, the process-cycle is long, manufacturing cost is high.
Summary of the invention
The purpose of this utility model is, be that for conventional method in sum, manufacturing flow skirt exists the problem that machine-finish allowance is large, the cycle is long, waste of material is large, manufacturing cost is high, provide one can make forging machine direction conformal distribute, machine-finish allowance is little, mechanical performance and service life improve, there is high temperature resistance, high pressure and corrosion resistance, the manufacture nuclear in-pile component that cost the is low mould of flow skirt.
The mould of flow skirt for manufacture nuclear in-pile component of the present utility model, includes impression die cavity, plug, core roller, reaming die cavity, packing ring, locking nut.On plug, be placed on reeded impression die cavity is set, form impression die cavity assembling die.On core roller, be placed on reeded reaming die cavity is set, reaming die cavity is anchored on core roller by packing ring, locking nut, forms reaming rolling ring die cavity assembling die.Impression die cavity assembling die, reaming rolling ring die cavity assembling die are made by metal material.
The flow skirt that the nuclear in-pile component that mould of the present utility model is made is used, its forging machine direction conformal distributes, and machine-finish allowance is little, and mechanical performance and service life improve, and have high temperature resistance, high pressure and corrosion resistance, and cost are low.

Fig. 3 is the front view of the circular material blank of the utility model use;
Fig. 4 is the stereogram that mould of the present utility model is manufactured the flow skirt of moulding.
The specific embodiment
Below in conjunction with above-mentioned accompanying drawing example, manufacture nuclear in-pile component of the present utility model is further described with the mould of flow skirt.
The mould example of flow skirt for manufacture nuclear in-pile component of the present utility model, includes impression die cavity 1, plug 2, core roller 3, reaming die cavity 4, packing ring 5, locking nut 6, circular material blank 7.
On plug 2, be placed in reeded impression die cavity 1 is set, form impression die cavity assembling die, plug 2 two ends are supported by the saddle of hydraulic press lower platform respectively.
On core roller 3, be placed in reeded reaming die cavity 4 is set, the upper and lower end of core roller 3 corresponds respectively to upper end and the lower table of ring rolls.During for ease of ring rolls rolling ring, prevent that reaming die cavity 4 from moving axially along core roller 3, reaming die cavity 4 is anchored on core roller 3 by packing ring 5, locking nut 6, forms reaming rolling ring die cavity assembling die.Impression die cavity assembling die, reaming rolling ring die cavity assembling die are made by metal material respectively.
While using the mould of manufacture nuclear in-pile component of the present utility model flow skirt, first the Heating Steel Ingots to 950 of refining～1150 ℃ to be placed on hydraulic press and repeatedly to be forged and pressed repeatedly, to change its structural state, seam internal flaw, then makes annular base with drift punching.Impression die cavity 1 is preheated to 250～350 ℃, after smearing release agent, be placed on the plug 2 being supported by the saddle of hydraulic press lower platform, again annular base is placed on impression die cavity 1, annular base on impression die cavity 1 moves to hydraulic press upper mounting plate with hydraulic press lower platform reaming, impression is carried out in annular base inner convex platform position, when small stair appears in annular base internal diameter, make circular material blank 7.
Circular material blank 7 is heated to after 950～1150 ℃, is placed on the reaming die cavity 4 that the core roller 3 on ring rolls installs, and guarantees that circular material blank 7 internal diameters and reaming die cavity 4 fit like a glove.Open ring rolls, cause circular material blank 7 inner convex platform sizes to flow along the groove of reaming die cavity 4, filling groove, circular material blank 7 reamings are to predetermined dimension size the most at last.Through comprehensive mechanical property, microstructure and corrosion-resistant, high-voltage detection, then through little surplus machining, make flow skirt 8 for nuclear in-pile component.
