Description

Hollow blade tool

Technical Field

The utility model belongs to the field of machinery, and particularly relates to a die tool.

Background

The nuclear power final hollow blade is welded by inner arc spot welding and back arc spot welding, and most importantly, the deformation of the blade in the welding process is prevented when the welding sequence is executed. The blade is generally clamped to the deformation-preventing welding tool. When the blades are clamped, the upper die is opened by means of a crane, the blades are assembled and then restored, and finally, the torque spanner sets torque and then screws the bolts. The whole process needs to be matched by a plurality of people, has complex operation and long time consumption.

Therefore, in order to reduce the weight of the upper die and lighten the module under the condition of the same pressing force, a crane can be not used when the upper die is opened, and a new upper die mode and a clamping tool are required to be researched so as to improve the clamping efficiency, reduce the working strength and improve the comprehensive operation efficiency.

Disclosure of Invention

Detailed Description

For a better understanding of the objects, structures and functions of the present utility model, a hollow vane tooling of the present utility model will be described in further detail with reference to the accompanying drawings.

Example 1

As shown in fig. 1 to 3, the technical scheme of the utility model comprises an upper die 2 and a lower die 3, wherein the upper die 2 and the lower die 3 are pressed together when in use, and the shape of the blade is kept from deforming when in welding. The lower die 3 is fixedly arranged on the machine table 1, and the upper die 2 is arranged on the machine table 1 through a connecting rod 8 and is positioned above the lower die 3; the upper die 2 is internally provided with a plurality of hollowed-out areas, and the weight of the die is reduced while the strength is maintained. The machine table 1 is provided with a plurality of compression cylinders 4, and the cylinders 4 are provided with clamping claws 41. The middle part of the clamping claw 41 is fixedly connected to the oil cylinder 4 through a rotating shaft, and the tail part of the clamping claw 41 is connected with an ejector rod of the oil cylinder 4. When the oil cylinder 4 runs, the ejector rod pushes the tail of the clamping jaw 41, and the end head of the clamping jaw 41 presses the blade on the lower die 3.

Example 2

In this embodiment, as shown in fig. 1, the claw 41 is connected with a profiling bead 5. The curve shape of the profiling pressing strip 5 is more provided with parameter setting of a blade finished product, and the profiling pressing strip 5 ensures that the blade edge is stressed more uniformly. Reducing deformation during and after welding.

Example 3

In the embodiment, the profiling pressing bar 5 is formed by splicing a plurality of profiling pressing blocks 51, each profiling pressing block 51 is independently connected with the clamping jaw 41, and each pressing cylinder 4 is controlled by an independent valve 6. Because the shape of the blade is irregular, the independent profiling pressing blocks 51 can ensure that the stress of each area is closer to a set value, and ensure that the blade is uniformly stressed and the processed shape of the blade is more stable.

In this embodiment, as shown in fig. 2 and 3, the connecting rod 8 passes through the machine 1 and is connected to the connecting plate 71, and the lifting cylinder 7 is disposed on the connecting plate 71, and the lifting cylinder 7 is connected to the machine 1.

Example 4

In the embodiment, the lower die 3 is movably arranged on the machine table 1 through a dovetail sliding plate, and a push-pull oil cylinder is further arranged on the machine table 1. During feeding, the lower die 3 is pulled out through the push-pull oil cylinder, so that the interference of the upper die 2 on space can be avoided, and the efficiency of the upper die is improved.
