Abstract
The utility model discloses an explosion-proof end flange which comprises an end flange body (1). A spigot type auxiliary explosion-proof surface (3) is arranged on a main explosion-proof surface (2) of the end flange body (1). An operator can use a spigot for positioning in assembly of a novel explosion-proof end cover and an end ring only by welding the end flange body with drilled bolt holes and other parts of the end cover into the end cover, lifting the end cover to a vertical lathe, fixing the end cover and machining the spigot type explosion-proof surface at a time, so that the assembly time is shortened, and the mechanical strength of a shell is improved.
Description
Technical field
The utility model relates to flameproof dry-type transformer housing technologies field, particularly a kind of novel flame proof end flanges in flameproof dry-type transformer end flanges technical field.
Background technology
Flameproof dry-type transformer end flanges is all plane at present, after itself and other weld parts of end cap machine-shaping, after the assembling of end circle, cannot guarantee under external impacts, attachment bolt is not sheared, so this end flanges mechanical strength is low, the production cycle is long, explosion insulation performance is general.
Utility model content
Utility model object: in order to overcome the defect of above-mentioned prior art, provide a kind of flame proof end flanges.
Technical scheme: a kind of flame proof end flanges, comprise end flanges, the auxiliary explosion suppresion surface of seam type is set on the main explosion suppresion surface of end flanges.
The utility model adopts technique scheme, has advantages of following beneficial effect: with short production cycle, mechanical strength is high, explosion insulation performance is high.
Accompanying drawing explanation
Fig. 1 is the front view of an embodiment of the utility model;
Fig. 2 is that the utility model embodiment Fig. 1 is along the cutaway view of A-A direction; In figure 1, end flanges; 2, main explosion suppresion surface; 3, seam type is auxiliary quick-fried.
Embodiment
Below in conjunction with specific embodiment, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As depicted in figs. 1 and 2, a kind of flame proof end flanges, comprises end flanges 1, and the auxiliary explosion suppresion surface 3 of seam type is set on the main explosion suppresion surface 2 of end flanges 1.
The method of work of this kind of device is: this utility model only needs operator to become after end cap joining other weld parts of end flanges and end cap that has bored bolt hole, after winching to and fixing on vertical car, time processing goes out seam type explosion suppresion surface, can reach when using novel explosion insulation shell with the assembling of end circle and can utilize seam location, reduce installation time, and improved the object of housing mechanical strength.
The implementation method of this kind of embodiment is first annulus to be divided equally and calculated the required arc length of blanking by three sections, with method of scoring or numerical control cutting machine blanking; After oscillating aging is processed; Winch to rough turn one-tenth welding required size on vertical car; After welding with end circle end flanges point again, join and get out the required bolt hole of diagram; Until becoming after end cap with other weld parts, after oscillating aging is processed, then shot-peening, primer spray, after priming paint parches, winch on vertical car and fastening, rear car goes out seam type explosion suppresion surface.
Claims (1)
1. a flame proof end flanges, is characterized in that, end flanges (1) is provided with the auxiliary explosion suppresion surface (3) of seam type on the main explosion suppresion surface (2) of described end flanges (1).
