Abstract
The utility model disclose a die for forging a flange joint pipe cylindrical shell in a large-scale reactor pressure vessel and belongs to the technical field of forging. The die for forging the flange joint pipe cylindrical shell in the large-scale reactor pressure vessel consists of an upper hammer, a step sleeve, a mandrel, mandrel supports, and a movable working platform; the lower end of the upper hammer is made into a longitudinal hammer with steps; stepped cylindrical shell sections are formed on the surfaces of the inner circular hole and the outer circle of the step sleeve; the upper end of the upper hammer is fixedly connected to a hydraulic press through a connection hole; the mandrel is arranged in the inner hole of the step sleeve; the lower end of the mandrel is provided with the mandrel supports; and the mandrel supports are arranged on the movable working platform. The flange joint pipe cylindrical shell is forged by using the whole die, so the completeness of a metal flow line in a flange joint pipe cylindrical shell body is effectively guaranteed, the whole flange joint pipe cylindrical shell is high in intensity, the sizes of all parts are accurate, and profiling and near net shape forging is realized.
Description
Technical field
the utility model relates to the forging mold of the flange adapter cylindrical shell in a kind of large-scale nuclear reactor pressure container, belongs to technical field of forging.
Background technology
Flange in
large-scale nuclear reactor pressure container is taken over cylindrical shell and is its critical component, and is complex-shaped, radial and axial size super large, and interior external diameter all has step at length direction.Because the solid forging of specification requirement body is processed, the present domestic flange adapter cylindrical shell integration system technology for making that also do not possess.
Summary of the invention
are in order to overcome the deficiency on the above-mentioned FMT; The utility model provides the flange in a kind of large-scale nuclear reactor pressure container to take over the forging mold of cylindrical shell; The forging mold that flange in this large-scale nuclear reactor pressure container is taken over cylindrical shell can not only forge flange adapter cylindrical shell, and forges its shape near-net forming of back.
the utility model solves the technical scheme that its technical barrier adopted: the flange in the large-scale nuclear reactor pressure container is taken over the forging mold of cylindrical shell and is made up of upper ram, step cover, saddle, saddle support, travelling table; The vertical tup that has step is processed in the upper ram lower end; The interior circular hole and the outer round surface of step cover are the stepped ramp type shell ring; The upper ram upper end is fixedly connected on the hydraulic press through connecting hole; Saddle is inserted in the step cover endoporus, and the saddle lower end is provided with saddle support, and saddle support is located on the travelling table.
The beneficial effect of
the utility model is: forge with a whole set of mould because flange is taken over cylindrical shell; Effectively guaranteed the complete of the interior metal streamline of flange adapter cylindrical shell body; Good integral strength, the each several part size is accurate, has realized that profiling, near-net forming forge.
Description of drawings
Fig. 1 is the forging mold structure chart that the flange in the large-scale nuclear reactor pressure container of the utility model is taken over cylindrical shell.
Fig. 2 is the forging mold left view that the flange in the large-scale nuclear reactor pressure container of the utility model is taken over cylindrical shell.
Among
figure 1, upper ram, 2, flange takes over cylindrical shell, 3, the step cover, 4, saddle, 5, saddle support, 6, travelling table.
The specific embodiment
are like Fig. 1-shown in Figure 2; Flange in the large-scale nuclear reactor pressure container is taken over the forging mold of cylindrical shell and is made up of upper ram, step cover, saddle support, saddle, travelling table; The vertical tup that has step is processed in upper ram 1 lower end; The interior circular hole and the outer round surface of step cover 3 are the stepped ramp type shell ring, and upper ram 1 upper end is fixedly connected on the hydraulic press through connecting hole, and saddle 4 is inserted step and overlapped in 3 endoporus; Saddle 4 lower ends are provided with saddle support 5, and saddle support 5 is located on the travelling table 6.
flange is taken over the forging stock of cylindrical shell 2 after forging, reaming just; Step cover 3 and saddle 4 are hung in flange to be taken in the endoporus of cylindrical shell 2; Lifting places on the saddle support 5 from saddle 4 two ends, and travelling table 6 is transported to mould and forging under the hydraulic press together, and upper ram 1 moves up and down; Saddle 4 changes at the outside force underspin, begins to forge to flange adapter cylinder forgings finished size.
The shape sized that
upper ram 1 and step cover 3 are taken over cylindrical shell 2 according to institute's flange of forging disposes saddle 4 and saddle support 5 according to the forging geomery.
Claims (1)
1. the flange in the large-scale nuclear reactor pressure container is taken over the forging mold of cylindrical shell; Form by upper ram, step cover, saddle, saddle support, travelling table; It is characterized in that: the vertical tup that has step is processed in upper ram (1) lower end; The interior circular hole of step cover (3) and outer round surface are the stepped ramp type shell ring, and upper ram (1) upper end is fixedly connected on the hydraulic press through connecting hole, and saddle (4) is inserted in step cover (3) endoporus; Saddle (4) lower end is provided with saddle support (5), and saddle support (5) is located on the travelling table (6).
