Description
Technical field
The invention belongs to forging technology fields, are mainly concerned with a kind of ITER project (International Thermal-Nuclear Experimental Reactor)
Blank design used in 316LN U-typed forging integrally bending forming technique.
Background technique
316LN U-typed forging, as shown in Figure 2.316LN material belongs to austenite structure, no ppolymorphism transformation, crystal grain
Degree can not be refined by heat treatment, therefore, only guarantee forging by controlled forge process technological parameter and process
Grain size.Again due in irregular shape, the reasons such as material deformation temperature range is narrow, and material resistance of deformation is big are difficult directly to forge
Forming.Former design scheme is that plate and forging are welded, but since wall thickness difference is larger, thinnest part only has 10mm, welding
Deformation is big and welding position grain size is coarse, is unable to satisfy product requirement.
Chinese patent disclose a kind of thermonuclear fusion heap ears U-shaped forging forging method (patent No.:
2014104241045), using two pieces blank conjunction be swaged into round billet material, then forge squarely forging, after cutting again single-piece carry out at
Swaged forging is made, and this method has the following problems:
1, since product geometric dimension is larger and material is 316LN austenitic stainless steel, forging times are more, in last igneous
It cannot be guaranteed that all positions of forging are all deformed (deflection is greater than 20%) when type, not can guarantee the equal of forging entirety grain size
Even property；It is relatively high to the skill requirement of operator, there is bigger dependence, so that the technology scope of application is limited；
2, when by round forging rectangularity forging, bottom cylindrical angle is larger (R >=300), to form the outer of final forging
Fillet R≤30, difficulty is bigger, and how to realize in above-mentioned patent without being described in detail；
3, in final pulling, formed punch is placed among U-shaped forging forging, since formed punch can not be fixed effectively, pulling is caused to be imitated
Rate is relatively low.
4, during curved, bottom cylindrical angle is acted on slab due to Tensile, it may appear that compared with Rouno Cormer Pregrinding Wheel, it is difficult to meet
Forging's block dimension requirement, while the compressed effect of blank inner surface crooked position will cause the accumulation of material to occur folding and split
Line.
Summary of the invention
It is an object of the invention in view of the problems of the existing technology, propose bull nose pre-compensation, inner surface dispersion
The plate bending forming technique of material accumulation, by innovative design blank shape, to make the forging's block dimension of brake forming
It meets the requirements.
In order to solve the above technical problems, the present invention adopts the following technical solutions:
ITER project U-typed forging brake forming slab, including slab lug boss 1, slab straight section portion 2, slab vertical bar portion 3
With slab curvature portion 4, above four are at two and to be symmetrical set;The slab lug boss 1 is set to slab bottom, described
Slab straight section portion 2 is set to slab end, and slab straight section portion 2 is set to slab end, and slab curvature portion 4 is set to slab
Top is equipped with slab vertical bar portion 3 between slab straight section portion 2 and slab curvature portion 4, is equipped in the center on slab top
One groove.
By adopting the above technical scheme the utility model has the advantages that
1, the configuration of the present invention is simple, forging drawing efficiency are high.
2, for slab of the present invention during curved, bottom cylindrical angle is not in be satisfied forging forging compared with Rouno Cormer Pregrinding Wheel
Size is met the requirements.
3, accumulation of the slab of the present invention without material, thus unfolded crackle.
Detailed description of the invention

In figure: 1- slab lug boss, 2- slab straight section portion, 3- slab vertical bar portion, 4- slab curvature portion.
Fig. 2 system 316LN material U-typed forging drawing.
In figure: 5- bull nose, 6- straight section, 7- lug.
Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail, but not that should not be interpreted as theme of the present invention with regard to this
Range is only limitted to embodiment below, without departing from the idea case in the present invention described above, all according to ordinary skill
Various modifications, replacement and the change that knowledge and customary means are made, are included within the scope of the present invention.
As shown in Figure 1, ITER project U-typed forging brake forming slab, including slab lug boss 1, slab straight section
Portion 2, slab vertical bar portion 3 and slab curvature portion 4, above four are at two and to be symmetrical set;
The slab lug boss 1 is set to slab bottom, and slab straight section portion 2 is set to slab end, slab straight section portion 2
Set on slab end, slab curvature portion 4 is set to slab top, is equipped between slab straight section portion 2 and slab curvature portion 4
Slab vertical bar portion 3 is equipped with a groove in the center on slab top.
Application note of the present invention:
As shown in Fig. 2, calculating the length of run of U-typed forging first, U-typed forging is divided into bottom, straight section 6 and lug 7
It calculates separately；When designing slab blank, slab lug boss 1 is used to compensate U-typed bottom cylindrical caused by slab bend tension
The scarce material problem at angle 5, slab straight section portion 2 is designed to equal with the volume of U-typed forging lug 7, and slab vertical bar portion 3 is designed to
Equal with the volume of U-typed forging straight section 6, slab curvature portion 4 is used to disperse material caused by plate bending compression and gathers.
