Abstract
The utility model provides a bellows end compacting tool set, includes mould shell, core, its characterized in that the mould shell comprises mould upper portion, changeover portion, mould lower part, mould upper portion internal diameter slightly is less than mould lower part internal diameter, the changeover portion is 40-60 degrees with the angle of horizontal plane, still include pressure head and lower pressure head. Can be with the one step of shaping in bellows end, avoided carrying out cutting process and the cost -push and the material that cause are extravagant.
Description
Technical field
The present invention relates to a kind of bellows termination compacting tool set.
Background technology
Polytetrafluoroethylbellows bellows sealing is flexible, pliable and tough, can make up the shortcoming that pushing pipe is difficult to assemble, and can adapt to the trace change in length.Not only can absorb moving and vibrating along pipeline and associated machine, and save again space, calculate the advantages such as dress soon.Traditional bellows termination compacting tool set mostly is straight barrel type by after molded for workpiece sintering, carries out machining.Because of machining, cost is caused to increase and material waste.
Summary of the invention
In order to the utility model that solves the problem provides a kind of bellows termination compacting tool set, can by first for bellows end one-step forming, avoid and carry out machining and the cost that causes increases and material waste.
Scheme of the present utility model is, a kind of bellows termination compacting tool set, comprise mold shell, fuse, it is characterized in that described mold shell is made up of mould upstream, changeover portion, mould bottom, described mould upstream internal diameter is slightly less than mould lower inner diameter, and the angle of described changeover portion and horizontal plane is 40 ~ 60 degree; Also comprise seaming chuck and push-down head.
Further, described changeover portion and mould upstream and junction, mould bottom are arc-shaped transition design.
Further, the angle of described changeover portion and horizontal plane is 45 degree.
Further, seaming chuck and push-down head are annular.
The beneficial effects of the utility model are, by first for bellows end one-step forming, avoid and carry out machining and the cost that causes increases and material waste.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional schematic;
In figure, 1 shell, 2 fuses, 3 seaming chucks, 4 push-down heads, 11 mould upstream, 12 changeover portions, 13 mould bottoms.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
A kind of bellows termination compacting tool set, comprise mold shell 1, fuse 2, mold shell is made up of mould upstream 11, changeover portion 12, mould bottom 13, and described mould upstream 11 internal diameter is slightly less than mould bottom 13 internal diameter, and described changeover portion 12 is 45 degree with the angle of horizontal plane; Also comprise seaming chuck 3 and push-down head 4.
Concrete, described changeover portion 12 is arc-shaped transition design with mould upstream 11 and junction, mould bottom 13.
Concrete, seaming chuck 3 and push-down head 4 are annular.
During use, fuse 2 is placed on the center position of mold shell 1, according to the length of the workpiece determination seaming chuck 3 and push-down head 4 of asking for making, push-down head 4 is placed on the gap of fuse 2 and mold shell 1, then polytetrafluoroethylmaterial material is put into, finally put into seaming chuck, compacting of then pressurizeing, sinter molding.
