Abstract
The utility model relates to a tank cover anti-deformation tool, and belongs to the technical field of transformer manufacturing. The technical scheme is that the tank cover anti-deformation tool comprises a main correction beam (1), support bodies (2), fixing devices (3) and a support (4). The upper portions of the two support bodies are sleeved on the main correction beam and in sliding connection with the main correction beam. The lower portions of the two support bodies are respectively provided with the fixing devices, and the main correction beam is placed on the support. The tank cover anti-deformation toll has the advantages that the degree of predeformation of a tank cover and the deformation and correction of finished products can be controlled by being matched with a jack, the jack makes mechanical correction to the position with large deformation of the tank cover, conciseness and reliability are achieved, the control of the release of internal stress in welding process can be achieved, the predeformation can be adjusted according to the different structural characteristics of each product, time saving and labor saving are achieved, and later flame straightening is reduced.
Description
Technical field
The utility model relates to a kind of case lid Anti-deformation tooling, belongs to technical field of transformer manufacturing.
Background technology
At present, barrel type tank type transformer, case lid are in the middle of welding process, and owing to reasons such as welding heat production, internal stress slowly discharges, and causes the case lid distortion serious, and subsequent adjustment is difficulty relatively, wastes time and energy, and has increased processing cost.And a lot of distortion are arranged is permanent types, and after proofreading and correct through traditional approachs such as flame, hammerings, surface smoothness can not guarantee, the presentation quality after impact is sprayed paint.
The utility model content
The purpose of this utility model provides a kind of case lid Anti-deformation tooling, succinct reliable, can realize controlling in the welding process internal stresses release, and can be according to the different structure adjustment of features predeformation amount of every product, time saving and energy saving, reduce follow-up flame straightening, solve the problems referred to above that background technology exists.
The technical solution of the utility model is: the case lid Anti-deformation tooling, comprise main beam, supporter, fixture and the support proofreaied and correct, the top of two supporters is enclosed within main the correction on the beam, be slidingly connected with the main beam of proofreading and correct, the bottom of two supporters arranges respectively fixture, and the main beam of proofreading and correct is placed on the support.
Described fixture is bolt, is bolted on the case lid of oil tank of transformer to be welded.
Use the utility model, be fixed on the case lid to be welded, the keypoint part emphasis is strengthened reversible deformation control; Judge case lid deflection deformation position by the operator, select suitable Support Position and anti-deformation size.Because different employees' work habit is different, the case lid design is different, and welding bead density is not equal, and the design that can change flexibly case lid deflection size seems particularly important, case lid bolts at two ends hole is fixed on the fixture, jack is placed on distortion easily sends out the position.Welding is finished after case lid cools off naturally and case lid is pulled down again, and so just the welding deformation amount of case lid has been dropped to minimumly, has reduced the workload of flame correction, has guaranteed the compression of seal gasket.
Good effect of the present utility model: cooperate jack can control the degree of case lid predeformation amount and the straightening of finished product, the position that jack is large with the case lid deflection is carried out machinery and is corrected, succinct reliable, can realize controlling in the welding process internal stresses release, and can be according to the different structure adjustment of features predeformation amount of every product, time saving and energy saving, reduce follow-up flame straightening.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment;
Among the figure: main beam 1, supporter 2, fixture 3, the support 4 proofreaied and correct.
Embodiment
Below in conjunction with accompanying drawing, by embodiment the utility model is described further.
The case lid Anti-deformation tooling, comprise main top of proofreading and correct beam 1, supporter 2, fixture 3 and 4, two supporters of support and be enclosed within main the correction on the beam, be slidingly connected with the main beam of proofreading and correct, the bottom of two supporters arranges respectively fixture, and the main beam of proofreading and correct is placed on the support.Described fixture is bolt, is bolted on the case lid of oil tank of transformer to be welded.
In an embodiment, can control the degree of case lid predeformation amount and the straightening of finished product by jack, the machinery rectification is carried out in the position that jack is large with the case lid deflection, has avoided the waste of flame straightening.Two supporters can left and right adjusting, the conveniently use of different big and small box covers.
Claims (2)
1. case lid Anti-deformation tooling, it is characterized in that: comprise main beam (1), supporter (2), fixture (3) and the support (4) proofreaied and correct, the top of two supporters is enclosed within main the correction on the beam, be slidingly connected with the main beam of proofreading and correct, the bottom of two supporters arranges respectively fixture, and the main beam of proofreading and correct is placed on the support.
2. described case lid Anti-deformation tooling according to claim 1 is characterized in that described fixture is bolt.
