A filling device that is used for supplementary filler material before tubular product bending

The utility model provides a filling device that is used for supplementary filler material before tubular product bending, includes the barrel, holds high temperature medium in the barrel, and the glass test tube is placed in the barrel, and the pipe is located the glass in vitro, and through the intraductal packing tin bismuth alloy solution of watering spoon guide, partial tin bismuth alloy solution is flowed by the bottom of pipe to the adhesion is in the glass test tube. High temperature medium in the barrel can make the pipe keep warm, when tin bismuth alloy solution waters in the pipe, tin bismuth alloy solution can not the condensation, it is more smooth and easy to flow, the in vitro in glass is placed naturally to the pipe simultaneously, when the intraductal watering of tin bismuth alloy solution guide, tin bismuth alloy solution can be flowed by the bottom of pipe, air in the pipe can be discharged to this in -process, it expires in the pipe to make tin bismuth alloy solution fill, fill closely kni
