Abstract
The utility model discloses a flanging device for a central hole of a convex sealing head in a pressure container, which has a simple structure and is convenient to process. The flanging device comprises a bracket and at least three upright posts arranged on the bracket, wherein the bracket are provided with a hydraulic jack; the upright posts and the hydraulic jack are positioned on the same side of the bracket; and the end part of a screw rod of the hydraulic jack is provided with a round-table punching head for flanging the central hole of the concave sealing head. The flanging device for the central hole of the concave sealing head in the pressure container has the advantages of simple structure, and convenience, easiness and high efficiency for processing of the concave sealing head.
Description
Technical field
The utility model relates to a kind of hemmer of pressure vessel camber end socket centre bore.
Background technology
Convex head occupation rate on pressure vessel and equipment is a lot, particularly on the mixing plant of jacketed occupation rate more than 95%.Conventional in the past way was: because the convex head volume is bigger, need utilize the large pressing machine of end socket factory to go to process to end socket factory to the processing of convex head central hole.This processing method duration is longer, but also wants customized mould, and expense is higher.
The utility model content
The utility model technical problem to be solved is: provide a kind of simple in structure, process the hemmer of pressure vessel camber end socket centre bore efficiently.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of hemmer of pressure vessel camber end socket centre bore; Comprise support and be arranged at least three columns on the support; Support is provided with hydraulic jack, and column and hydraulic jack are positioned at the support homonymy, and the screw rod end of hydraulic jack is provided with the truncated cone-shaped drift that is used for the convex head central hole is carried out flange.
The beneficial effect of the utility model is: the hemmer of the pressure vessel camber end socket centre bore of said structure, simple in structure, the processing convex head is convenient, simple, efficient is high.
Description of drawings
Structure chart when Fig. 1 is the work of hemmer of the utility model pressure vessel camber end socket centre bore.
Among the figure: 1, support, 2, column, 3, hydraulic jack, 4, convex head, 5, drift.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
As shown in Figure 1, a kind of hemmer of pressure vessel camber end socket centre bore comprises support 1 and is arranged at least three columns 2 on the support 1 that the quantity of column 2 can be decided according to actual conditions.Support 1 is provided with hydraulic jack 3, and column 2 is positioned at support 1 homonymy with hydraulic jack 3, and the screw rod end of hydraulic jack 3 is provided with the truncated cone-shaped drift 5 that is used for convex head 4 central hole are carried out flange.
The operation principle of the utility model is: earlier column 2 and support 1 are welded together; Then with the other end of column 2 be welded on respectively convex head 4 centre bores around; Base with hydraulic jack 3 withstands support 1 again; The small end of truncated cone-shaped drift 5 is filled in the centre bore in the convex head 4, and an end of the screw rod of hydraulic jack 3 withstands on the big end end face of truncated cone-shaped drift 5, utilize at last hydraulic jack 3 with truncated cone-shaped drift 5 to pressing down; Drift 5 enlarges centre bore in the process that presses down and makes its edge flange, thereby realizes the flange processing of convex head 4.Because column 2 is welded on the convex head 4; Given hydraulic jack 3 one good processing base face; Need not to install and made its fixing fixture to convex head 4; Utilize internal force between flange frock and the convex head 4 just can accomplish the processing work of flange, reduced unnecessary outside large-scale fixture.After machining, unload hydraulic jack 3 and drift 5, and column 2 gas cutting from the convex head 4 is got off to get final product.
