Abstract
The utility model belongs to the technical field of transformer manufacturing, and particularly relates to a pin bolt-free transformer iron core drawplate, which comprises a drawplate (1) and a clamping piece (4). The pin bolt-free transformer iron core drawplate is characterized in that a first reinforcing plate (2) is fixed on the drawplate (1), a second reinforcing plate (3) is fixed on the clamping piece (4), an insertion unit (5) is arranged on the first reinforcing plate (2) and an accommodating unit (6) is arranged on the second reinforcing plate (3) correspondingly, and the drawplate (1) and the clamping piece (4) are matched together through the insertion unit (5) and the accommodating unit (6). The pin bolt-free transformer iron core drawplate provided by the utility model does not need to manufacture pin bolts and does not need to form holes on clamping piece and the drawplate, has more reliable strength and low cost, and can effectively simplify process.
Description
Technical field
The utility model belongs to technical field of transformer manufacturing, and particularly a kind of transformer does not have the iron core arm-tie of pin.
Background technology
The transformer core arm-tie is pin feature mostly, because pin is welded on the arm-tie, want perforate on folder and the arm-tie entirely, and the very heavy words pin size of device body can be bigger, and when making long-term the use,, influence the transformer pulling plate life-span easily in the tapping breakage owing to perforate, and this kind design production process just is tending towards complicated, and the arm-tie of no pin just can avoid this type of situation to take place.
Summary of the invention
The technical problem that solves
The utility model provides a kind of manufacturing of arm-tie at above-mentioned technical problem, and is simpler, and more convenient operation has reduced production cost.
Technical scheme
Technical solution of the present utility model is: a kind of transformer core arm-tie that does not have pin, comprise arm-tie and folder, it is characterized in that fixing on the arm-tie first stiffener, fix second stiffener on the folder, first stiffener is provided with plug-in unit, correspondence is provided with fitting on second stiffener with it, and arm-tie and folder are combined together by plug-in unit and fitting.
As the described plug connector of a kind of optimal way is projection and groove fit, also can be for falling the projection and the groove fit of trapezoidal shape, or common plug connector contact-making surface is a plane contact.
Beneficial effect
Do not need to make pin, need perforate on folder and arm-tie, the more reliable and effective simplified processing process process of intensity, cost is lower.
