Description

Semi-automatic PFA short pipe flaring device Technical Field The invention belongs to the technical field of FPA tube processing, and particularly relates to a semi-automatic PFA short tube flaring device. Background PFA materials are widely used for fluid transport of equipment in semiconductor manufacturing processes because of their excellent chemical stability and corrosion resistance, and often require a flaring process to better connect and install these conduits. At present, two flaring modes of cold flaring and hot flaring are mainly adopted in the industry, wherein the cold flaring mainly adopts a pressure mechanism die to expand the PFA hard tube to achieve the purpose of reaming, the PFA hard tube is easy to damage, and meanwhile, the tightness is not as good as that of hot flaring. The heat expansion mainly adopts a hot air gun to heat the PFA tube, and then the tube is expanded and formed through a die. As shown in fig. 5, in the case of a pipe joint for pipe connection, there is generally a nut, which is required to be inserted into a pipe and then heated to expand the pipe, but in the case of a pipe with a short connecting pipe, the nut is inserted at a relatively short distance and then is subjected to a flaring operation, so that it is required to increase the distance between connecting pipes, but this wastes a lot of space and increases the volume in the equipment. The need to flare the spool requires the purchase of ready-made flared fittings, which can add significant cost. Therefore, the technical scheme provides a semi-automatic PFA short pipe flaring device which is used for manufacturing a short-distance flaring connector.
