Abstract
The utility model discloses a structure of a transformer core fastened by rivets. After coils are winded on a coil framework, the transformer core is assembled into the coil framework. After being overlapped, the transformer core is fastened into a whole by four rivets. An insulating sleeve is sleeved on the outer side of the rod part of each rivet, the end of the insulating sleeve is arranged between the end of each rivet and the transformer core, and the riveting end of each rivet is provided with a stamping opening. The length of each insulating sleeve is less than or equal to the width of the transformer core, and the length of the rod part of each rivet is greater than the width of the transformer core. After assembly, a transformer is placed in a mould with the stamping openings at the riveting ends of the rivets being upward. The four rivets are stamped by using a stamping tool in one step, and after the stamping openings at the riveting ends of the rivets are deformed, the rivets are riveted on the transformer core. Due to the adoption of the insulation sleeves, the rivets are mostly isolated with the transformer core.
Description
Technical field
The utility model relates to a kind of parts of transformer core, specifically relates to the fastening rivet arrangement of a kind of transformer core.
Background technology
In the prior art, be tightened to one by four screw rods usually after transformer core is superimposed, manual with screwdriver that bolt and nut is fastening, efficiency of assembling is difficult to improve; In the use, bolt and nut can become flexible besides, makes transformer core can not paste the jail, has reduced the efficient of transformer.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, provides a kind of transformer core fastening rivet arrangement.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the fastening rivet arrangement of a kind of transformer core, comprise transformer core, four bight rivets of described transformer core, the bar portion outside of rivet is with insulating case, the termination of insulating case is arranged between the termination and transformer core of rivet, and the riveted joint end of rivet is provided with punched openings.After the assembling transformer is seated in the mould, the punched openings of rivet end up, use the punching press frock disposable with four rivet punching presses, after the distortion of the punched openings of rivet end with rivet on transformer core, insulating case makes that big of rivet is isolated with transformer core.
As preferably, the length of described insulating case is less than or equal to the width of transformer core, and the length of rivet bar portion is greater than the width of transformer core.
The utility model is easy to assembly, uses the disposable punching press riveted joint of punching press frock, the working (machining) efficiency height, and it is firm that the riveted joint back connects, and steady quality helps the efficient of stabilizing transformer.Therefore, the utlity model has characteristics such as simple in structure, reasonable in design.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model transformer;
Fig. 2 is a kind of A-A sectional structure schematic diagram of rivet among Fig. 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, after coil 1 is wound on the coil rack 2, again transformer core 3 assemblings are entered, transformer core 3 superimposed backs are tightened to one by four rivets 4 with transformer core 3, referring to Fig. 2, bar portion 41 outsides of rivet are with insulating case 44, the termination 45 of insulating case is arranged between the termination 42 and transformer core 3 of rivet, the riveted joint end 43 of rivet is provided with punched openings 46, the length of insulating case 44 is less than or equal to the width of transformer core 3, and the length of rivet bar portion 41 is greater than the width of transformer core 3.After the assembling transformer is seated in the mould, the punched openings of rivet end up, use the punching press frock disposable with four rivet punching presses, after the distortion of the punched openings of rivet end with rivet on transformer core, insulating case makes that big of rivet is isolated with transformer core.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection range of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
