Description

Integral pressing tool for tuyere large sleeve Technical Field The utility model belongs to the field of mechanical manufacturing processes, and particularly relates to an integral pressing tool for a tuyere large sleeve. Background The tuyere large sleeve used by the blast furnace body of a certain company is 34 groups, after the large sleeve is manufactured, the large sleeve is shipped to the site for debugging and installation (34 tuyere large sleeves are respectively combined with the tuyere flange on the reserved tuyere on the blast furnace body), as shown in fig. 2 and 3, the single tuyere large sleeve is of a multi-angle cylinder-mounted structure, the outer part of the single tuyere large sleeve is connected with the tuyere flange (the tuyere flange is mounted on the blast furnace body), the inner part of the single tuyere large sleeve is connected with the tuyere large sleeve in a matched manner, and the inner part and the outer part of the single tuyere large sleeve are cast and formed. Because the field belongs to subtropical ocean monsoon climate and is used on a blast furnace, the leakage of relevant gas is prevented, the requirement on the tightness of the large sleeve body is very high, and the working pressure is required to reach 0.4-0.6Mpa. The tuyere large sleeve is a multi-angle special-shaped cylindrical casting, and in order to ensure the overall tightness, an overall tightness experiment needs to be carried out on the tuyere large sleeve, the experimental pressure is 0.5Mpa, and the tuyere large sleeve is qualified after being maintained for 10 minutes without leakage. Because the structure is special, the sealing experiment is not carried out on the large tuyere sleeve alone in actual installation, but is carried out together with the two tuyere sleeves after being combined, and the method has the defects that high-level staff is needed to participate in process monitoring, the process workload is increased on the one hand, and the large tuyere sleeve needs to be disassembled and returned to be maintained after leakage occurs, so that the overall installation progress is influenced. Disclosure of utility model The utility model aims to provide an integral pressing tool for a tuyere large sleeve, which overcomes the defects of the prior art, realizes independent sealing experiments on the tuyere large sleeve, can timely treat the found problems, reduces the workload of on-site installation and disassembly, can improve the pressing efficiency and accuracy, ensures the tightness of the tuyere large sleeve, and meets the technical requirements of clients on the tightness of the tuyere large sleeve. In order to achieve the above purpose, the present utility model is realized by the following technical scheme: The utility model provides a frock is suppressed to big cover of wind gap wholly, its characterized in that includes upper panel, well tire pressure board and lower panel, the flange face phase-match of upper panel and big cover of wind gap is equipped with the mounting hole on the upper panel and is connected through the bolt with the flange hole on the flange face, the bottom surface phase-match of lower panel and big cover of wind gap all is equipped with the seal groove on the corresponding mating surface of upper panel and lower panel, is equipped with O shape circle in the seal groove, well tire pressure board cooperatees with the inboard locating table of bottom surface, and well tire pressure board is connected with lower panel through the bolt, and well tire pressure board's periphery evenly is equipped with everywhere opening, the size of opening is greater than the cross-section size of the big cover of wind gap inner side seat.
