Description
Technical field
The utility model relates to mould bending technology field, particularly relates to the hard crossbeam bending die of a kind of railway contact line.
Background technology
Along with the construction of China railways electrified development, particularly high-speed electric railway and the requirement of station landscape, in electrification railway contact net, the hard crossbeam of steel pipe is more and more adopted.Hard crossbeam is only applicable to the construction of some special field, electrification station in the past, in the lifting of railway speed increase and safety requirements in recent years, the electrification construction of the field, station, all stations that range of application expands gradually, hard crossbeam single hole span maximum at present can reach 52 meters, connects that span is maximum reaches 72 meters.
The hard crossbeam of steel pipe of or special occasions comparatively large for some spans, need the radian that design design is certain, also the hard crossbeam with certain camber will namely be produced, to ensure the stability of strutting system of hard crossbeam to contact wire, existing bending process is first bent by steel pipe respectively according to the radian of hard crossbeam, then the steel pipe of press-bending is dressed up sectional hard horizontal neck (side bar or central sill etc.), but the press-bending radian of steel pipe intuitively cannot be measured when bending, need repeatedly to adjust, therefore operating efficiency comparatively under, had a strong impact on speed of application.
Utility model content
For this reason, the technical problems to be solved in the utility model overcomes above shortcomings in the hard crossbeam manufacturing process of existing arch, then provide a kind of railway contact line hard crossbeam bending die, this grinding tool can directly measure press-bending radian, make bending process one-shot forming, and then answer is enhanced productivity, and avoids affecting construction speed.
For achieving the above object, the utility model is by the following technical solutions:
The hard crossbeam bending die of a kind of railway contact line, it comprises counterdie, the upper end of described counterdie is provided with the arc groove for steel pipe bending, the blunderbuss be provided with directly over described counterdie for the described steel pipe that bends is hammered into shape, the one or both ends of described arc groove are provided with protractor, the center that the pointer of described protractor is hinged on described protractor is pointed out, the end instruction number of degrees of the pointer of described protractor, the reverse extending section of described pointer is arranged on below the end of described steel pipe, described lower mould body is provided with the die cavity for described indicators turn; The central point of described protractor flushes with described steel tube end part, and the minimum point of below and described steel pipe that described central point is arranged on described steel pipe is in same level.
Preferably, the reverse extending section of described pointer is bundled in the below of described steel pipe by securing member.
Preferably, described securing member is rope or band.
Preferably, the base of described protractor and the end face of described steel pipe, the scale be positioned on horizontal line of described protractor is 0 degree, and the vertically vertical scale of described protractor is ± 90 degree.
Preferably, the lower pressure side of described blunderbuss hammer is arc-shaped structure.
The beneficial effects of the utility model:
The hard crossbeam bending die of railway contact line of the present utility model can intuitively measure the radian that steel pipe is bent by throughput hornwork, is convenient to workman and controls to press down dynamics, can realize a bent into shape, and then substantially increase production efficiency.
Accompanying drawing explanation
