Abstract

The utility model discloses a nonsymmetrical locking type semispherical clamping device which belongs to the technical field of the forging of hydraulic presses. A bracket is a square frame; an anvil block is arranged at the central position of the bracket; unsymmetrical clamping platforms are respectively arranged above the bracket; a base is arranged below the clamping platforms; a spring is mounted on a central rod of the base; a sliding sleeve is arranged at the lower end of the spring; the central rod of the base can slide vertically in the sliding sleeve; sliding seats are arranged at the upper ends of the clamping platforms; threaded screw nuts are arranged in the middle of the sliding seats; threaded telescopic screw rods are arranged in the threaded screw nuts; square cylinders capable of regulating the threaded telescopic screw rods are arranged at the rear ends of the threaded telescopic screw rods; and arc-shaped jack catches or abnormal jack catches are arranged at the front ends of the threaded telescopic screw rods. The nonsymmetrical locking type semispherical clamping device can realize the near-net shaping of a punched pipe nozzle of an end socket forge piece with a normal pipe mouth for a water chamber of a million-kilowatt nuclear power evaporator, and has the advantages of continuous fiber streamline of the forge piece, uniform deformation, good homogeneity, long service life, less machining allowance, high material utilization rate, short production period, low manufacturing cost and the like.

Description

Asymmetric locking type hemisphere clamping device
Technical field
the utility model relates to a kind of asymmetric locking type hemisphere clamping device, belongs to the dydraulic forging technical field.
Background technology
The gigawatt nuclear power evaporator water chamber head forging that band normal tubes is chewed is the vitals in the gigawatt nuclear power evaporator; Having 2 normal tubes at the dome head outer surface chews; Because forging ' s block dimension is bigger than normal, shape is more complicated also, so chew in the forming process at pipe; Its spatial positioning accuracy is very important, will cause forging integral body to be scrapped in case deviation takes place in the locus that pipe is chewed.If there is not suitable positioning clamping device,, can only adopt the cover type method to produce for the integrated head forging of this complicated shape; Promptly forge the blank that wall thickness is very big earlier, rely on the method for gouge and machined into to be shaped then, this manufacturing approach production cost is than higher; Allowance is big, and stock utilization is low, and production efficiency is low; The forging fibre flow is interrupted, and service life is short.
Summary of the invention
are in order to overcome the deficiency on the above-mentioned FMT; The utility model provides a kind of asymmetric locking type hemisphere clamping device; This asymmetric locking type hemisphere clamping device can not only be accurately with water chamber head space orientation in forging; And reduce forging allowance, realize near-net forming.
the utility model solves the technical scheme that its technical barrier adopted: support is a quadra; Its center is provided with anvil block; The support top is respectively equipped with asymmetric folder platform, and the folder platform has pedestal, is equipped with spring on the pedestal center-pole; The spring lower end is provided with sliding sleeve, and the pedestal center-pole can slide up and down in sliding sleeve; Folder platform upper end is provided with slide, is provided with the screw thread screw in the middle of the slide, is provided with the flexible leading screw of screw thread in the screw thread screw, and the flexible leading screw rear end of screw thread is provided with the square body of the flexible leading screw of scalable screw thread, and its front end is provided with arc claw or special-shaped claw.
The beneficial effect of the utility model is: can realize the gigawatt nuclear power evaporator water chamber head forging punching out ozzle near-net-shape chewed with normal tubes, have the forging fibre flow continuously, distortion evenly, good, the long service life of homogenieity, advantages such as allowance is few, stock utilization is high, with short production cycle, low cost of manufacture.
Description of drawings
Fig. 1 is the asymmetric locking type hemisphere of a utility model clamping device A-A sectional structure chart.
Fig. 2 is the asymmetric locking type hemisphere of the utility model clamping device plan structure figure.
Among figure 1, support, 2, spring, 3, pedestal, 4, Jia Tai, 5, the flexible leading screw of screw thread, 6, the arc claw, 7 special-shaped claws, 8, water chamber head, 9, anvil block, 10, sliding sleeve, 11, slide.
The specific embodiment
are like Fig. 1-shown in Figure 2; Support 1 is a quadra, and its center is provided with anvil block 9, and support 1 top is respectively equipped with asymmetric folder platform 4; Folder platform 4 has pedestal 3; Be equipped with spring 2 on pedestal 3 center-poles, spring 2 lower ends are provided with sliding sleeve 10, and pedestal 3 center-poles can slide up and down in sliding sleeve 10; Folder platform 4 upper ends are provided with slide 11, are provided with the screw thread screw in the middle of the slide 11, are provided with the flexible leading screw 5 of screw thread in the screw thread screw, and flexible leading screw 5 rear ends of screw thread are provided with the square body of the flexible leading screw 5 of scalable screw thread, and its front end is provided with arc claw 6 or special-shaped claw 7.
When use , adjust the flexible leading screw 5 of screw thread respectively to correct position, water chamber head is placed on the device upper end according to the arcuate profile size of water chamber head; The position of desiring the punching out ozzle is arranged at the upper end of anvil 9; By special-shaped claw 7 positioning and lockings, under the drift towards the time, device sinks immediately; By pedestal 3 center-poles in sliding sleeve 10 to lower slider, finish rear spring 2 towards mouth device resetted.
