Automobile oil tank opening tangent inverted flanging die structure

Abstract

The invention provides an automobile oil tank opening tangent inverted flanging die structure, and belongs to the technical field of automobile part machining. The automobile oil tank opening tangent inverted flanging die structure comprises a box body and a supporting plate, the interior of the box body is hollow, a limiting groove is formed in the box body, and a touch block is slidably connected with the interior of the limiting groove through a sliding groove; a rotating plate is rotationally connected with the right side of the box body through a rotating shaft, the rotating plate makes contact with the top end of the touch block in the rotating process, and a rotating rod is rotationally connected into the box body; a gear fixedly sleeves the outer surface of the right side of the rotating rod, a rack is fixedly connected with the rear end of the touch block, and the rack is meshed with the gear; and by arranging the rotating plate, chippings left on an oil tank after an oil tank shell is turned over can be shaken off, so that application of a first turning-over opening and a second turning-over opening in the oil tank shell after turning-over can be facilitated, and the defect that the chippings generated in the traditional oil tank turning-over process are embedded in the edge of the turning-over opening of the oil tank opening and are difficult to remove is overcome.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a mold structure for tangentially turning the fuel tank opening of an automobile. Background technique [0002] In order to facilitate the installation of fuel pipes for the fuel tank ports used in automobiles, when the fuel tank ports are processed, they need to be processed with inverted molds to meet the needs of fuel pipe welding. [0003] In the prior art, the patent whose publication number is CN204171135U discloses a ring section part turning device, which belongs to the technical field of aeroengine parts manufacturing. During the manufacturing process of aeroengine, some ring section parts need to be turned over. However, due to the limitation of the structure and shape of the ring section parts, multiple sets of auxiliary turning devices are used in the traditional turning process, because at this stage, it is still impossible to use one device to meet the...

[0003] In the prior art, the patent whose publication number is CN204171135U discloses a ring section part turning device, which belongs to the technical field of aeroengine parts manufacturing. During the manufacturing process of aeroengine, some ring section parts need to be turned over. However, due to the limitation of the structure and shape of the ring section parts, multiple sets of auxiliary turning devices are used in the traditional turning process, because at this stage, it is still impossible to use one device to meet the requirements of reliable positioning and eliminate springback at the same time, and multiple sets are used. The device realizes mouth-turning processing, and each device needs to be equipped with hydraulic equipment once before processing, so it takes a lot of auxiliary time and occupies the hydraulic equipment for a long time, resulting in a reduction in the actual operation time of the hydraulic equipment and resulting in low actual production efficiency. The above utility model Compared with the existing technology, it can realize one-time processing and forming, and a set of devices can meet the requirements of reliable positioning and elimination of springback at the same time, without spending a lot of auxiliary time, ensuring the actual operation time of hydraulic equipment and effectively improving production efficiency , however, during the use of the mouth turning device, the debris generated by turning the mouth is easy to accumulate in the turning of the fuel tank, which is not conducive to the installation of the fuel pipe on the fuel tank.
