Description
Technical field
The utility model belongs to steel pipe forming technical field, and in particular to a kind of tuber strip center shaping mechanism.
Background technique
Steel pipe is usually by the way that by strip cans, when forming production steel pipe with Continuous Roller, forming process is big
Cause can be divided into band steel edge formative stage, center pre-profiling stage, center formative stage and tube reducing stage.
Application No. is the Chinese utility model patent of CN88101905 disclose a kind of forming method in tuber and its
Equipment, the molding equipment include two roller frame being oppositely arranged, and a upper roll shaft and a lower roller shaft are fixed between roller frame, on
Roll shaft installation is there are two upper roller, and there are two lower rolls for installation on lower roller shaft, and lower roll and upper roller are oppositely arranged；It is also equipped on lower roller shaft
Two intermediate calender rolls are provided with separator between intermediate calender rolls, between intermediate calender rolls and lower roll to ensure that each lower roll and intermediate calender rolls are in phase
On the position answered.
Upper roller, lower roll, intermediate calender rolls, which cooperate, to be suitable for producing the steel pipe from the various diameters in wider range；When at
When being bent band steel edge in the sizable steel pipe of type diameter, the spacing of roller can be changed according to bandwidth, so as to a pair of of side roller positioning
In the opposite end of the strip of required width, the roll surface of side roller is upward；It needs to be arranged on upper roll shaft simultaneously a pair of intermediate
Roller, and upper intermediate calender rolls are navigated to the central part of strip.
And in the pre-profiling stage of strip center, the roll surface (i.e. compression aspect) of side roller is needed from changing to transverse direction upward,
So that strip is shaped to semicircle or 2/3rds circles；In the formative stage of center, the roll surface of side roller need to be then court from lateral transition
Under, while also needing to replace above-mentioned intermediate calender rolls using a vertically moving lower horizontal roller, so that strip is shaped to substantially
Circle.
The molding equipment is disadvantageous in that: (1) side roller for needing to use in strip central part forming process is independent
