Description
Technical field
The present invention relates to cover plate shaping methods and aid for a kind of transformer transporting, belong to transformer technology field.
Background technology
At present, in the cover plate of transformer and high voltage distribution installation transportation, there are a large amount of special-shaped cover plates, with reference to accompanying drawing 3,4, after welding fabrication, because special-shaped cover slab plate is thin, middle steel-pipe welding, unavoidably produces welding deformation, and traditional shaping methods is for being used hydraulic press, along special-shaped cover panel edges, with hydraulic press tup, press successively one time, shaping effect is undesirable, and sometimes produces wave transformation, time-consuming, efficiency is low, can not meet production requirement.
Summary of the invention
The object of the invention is to provide cover plate shaping methods and aid for a kind of transformer transporting, only needs 1～2 adjustment dynamics of hydraulic press pressure testing, just can reach the good leveling effect of special-shaped cover plate, solves the problem existing in background technology.
Technical scheme of the present invention is:
Cover plate shaping aid for a kind of transformer transporting, comprise reinforcement steel ring, thick walled steel tube, lower reinforcement steel ring and circular hole, thick walled steel tube internal diameter is greater than cover plate boss diameter for transformer transporting, length is greater than transformer transporting cover plate land length, upper and lower two ends are fixing upper steel ring and the lower reinforcement steel ring strengthened respectively, upper reinforcement steel ring size matches with cover plate with transformer transporting, center is provided with circular hole, Circularhole diameter equals thick walled steel tube internal diameter, and on same center line, lower reinforcement steel ring is placed on hydraulic press platform.
Described lower reinforcement steel ring diameter is greater than thick walled steel tube external diameter.Make transformer transporting in hydraulic press pressure testing process, keep more stable with cover plate shaping aid.
A kind of transformer transporting cover plate shaping methods, adopt above-mentioned aid to carry out, comprise following steps: 1. aid comprises reinforcement steel ring, thick walled steel tube, lower reinforcement steel ring and circular hole, thick walled steel tube internal diameter is greater than cover plate boss diameter for transformer transporting, length is greater than transformer transporting cover plate land length, upper and lower two ends are fixing upper steel ring and the lower reinforcement steel ring strengthened respectively, upper reinforcement steel ring size matches with cover plate with transformer transporting, center is provided with circular hole, Circularhole diameter equals thick walled steel tube internal diameter, and on same center line, lower reinforcement steel ring is placed on hydraulic press platform, 2. transformer transporting is placed in cover plate boss in the thick walled steel tube of aid, transformer transporting is supportted by the upper reinforcement steel ring holder of aid with the edge of cover plate, makes the stressed uniformity in whole border, 3. with hydraulic press tup, at transformer transporting, with cover plate center, exert pressure, exert pressure after 1～2 time, the shaping effect of cover plate for range estimation transformer transporting, adjusts pressure size, finally reaches transformer transporting and flattens effect with cover plate.
The invention has the beneficial effects as follows: transformer transporting is effective with cover plate shaping leveling, can meet production requirement, and labor strength is low, and efficiency is high, single-piece operating efficiency can improve 7-10 doubly, has feature simple in structure, easy to use.
