Technical field
The utility model belongs to pipe bending field shaping technique, and in particular to a kind of brake forming of aviation petroleum pipeline Device.
Background technique
Aviation petroleum pipeline is a kind of major-diameter thick-wall pipe fitting, due to needing to connect with pipeline road after the bending of aviation petroleum pipeline It connects, so aviation petroleum pipeline two ends require flaring at horn-like, i.e. the both ends of aviation petroleum pipeline are required to flat ozzle And cap nut, flat ozzle, which is used to match with the shape after pipe fitting expanding, plays the role of sealing, and cap nut is for protecting Flat ozzle, connecting line play locking.
Pipe fitting brake forming is a kind of relatively conventional processing method.It cannot achieve larger diameter using CNC tube bending machine to lead Pipe brake forming.Manual bending is mostly used in actual processing, worker's amount of labour is big, productivity is low.Diameter is slightly smaller may be used also With, but if the larger or diameter of batch is thicker, the labor intensity of worker is conceivable.Simultaneously as aviation oil transportation The presence of the both ends flared region of pipe, worker easily deforms when being bent, while injuring flared region.
The Chinese utility model that Authorization Notice No. is CN104384262B discloses a kind of guiding-tube bend molding equipment and leads Pipe bending and molding method, can be realized the molding of 4~Ф of Ф, 18 different tube diameters guiding-tube bend, and the guiding-tube bend molding equipment is constituted It is as follows: bushing, connector, articulated arm, mandrel, fixing seat, rotating slideway, pin, idler wheel, handle, collet;The mandrel passes through Bushing and connector are fixed in fixing seat, and rotating slideway is hollow ring structure, and rotating slideway passes through support casing in mandrel, The guiding-tube bend molding equipment improves the processing quality of part, meets real-life requirement.There are upper for the device The presence of the specifically mentioned both ends flared region due to aviation petroleum pipeline is stated, and the bending region of flared region and design is separated by It is not far, the case where straightway when worker is bent among aviation petroleum pipeline easily deforms, while while being bent injures flared region.
Therefore, it is necessary to a kind of aviation petroleum pipeline bend molding apparatus for not injuring pipe fitting expanding region in brake forming.
Utility model content
The purpose of this utility model is that: straightway is damaged when in order to avoid appearing in brake forming and injures pipe fitting The case where flared region, provides a kind of major-diameter thick-wall aviation petroleum pipeline bend molding apparatus.
The technical solution adopted in the utility model is as follows:
A kind of major-diameter thick-wall aviation petroleum pipeline bend molding apparatus, including fixing seat are provided with positioning seat in fixing seat, It is also hinged with cursor in fixing seat, forming roller is provided on cursor, positioning seat is set as cylindric, the lateral wall of positioning seat On be provided with the pipe fitting mounting groove of annular, be provided with gap slot on positioning seat, short side wall, the long side wall of gap slot are mutually perpendicular to, Fixed block is additionally provided in fixing seat, fixed block is adapted at a distance from long side wall with the outer diameter of aviation petroleum pipeline.
Further, the axis on positioning seat along positioning seat is provided with mounting hole, and mandrel, cursor are arranged in mounting hole It is set in mandrel.
Further, forming roller is arranged in cursor bottom, and the axis of forming roller intersects with the axis of cursor.
Further, annular groove is provided on the lateral wall of forming roller, the section of annular groove is set as semicircle.
