Description
Technical field
The utility model relates to a kind of pressurizing unit of welded tube, specifically the adjustable welded tube extruding drive unit of a kind of extruded hole.
Background technology
Welded tube is in actual production, stainless steel tube need to be pushed to then welding, normally stainless steel tube constant speed running under the effect of horizontal compression roller, then the steel-pipe welding with welding gun, horizontal compression roller being pushed, common horizontal compression roller is provided with a home roll and is driven by driving mechanism, secondary roller is as driven voller, or promote welded tube under the impetus of external force, under the effect of tube fraction power, compression roller rotation is advanced, but owing to being to have certain distance between home roll and secondary roller, start extruding just, when steel band is sent to compression roller, can cause master, slight asynchronous of secondary roller, the accuracy of weld seam coupling reduces, cause weld seam welding easily to produce skew, increase the stress at weld seam position, weld seam is easy to crumble.
And most of pressurizing unit is all fixedly installed now, the distance of major and minor roll shaft just cannot change after determining, even if can adjust, also must be quite difficult, if in the time that the width of welded tube is larger, easily there is lap-welded situation, and in the time that welded tube is narrow, easily occur the situations such as solder skip, affected quality and the qualification rate of welded tube.
Also there are in addition some to regulate the device of welded tube extruded hole, conventionally regulate by feed screw nut and spring fastenings, although can solve the problem that extruded hole regulates, but because feed screw nut and spring fastenings are all to pass through manual adjustments, cause the precision of adjusting too low, still can affect the quality of welded tube.
