Description
Technical field
This technology belongs to large diameter thick wall steel pipe production technical field, and in particular to a kind of more specification square tube rolling forming lifes
Producing line.
Background technology
Heavy caliber thick wall rectangular steel tube, also referred to as steel cold-forming shapes, it is using steel flat board as mother metal, is processed through cold bend(ing)
After shaping, then form through high-frequency welding, heavy caliber thick wall rectangular steel tube has been widely used in numerous industries.
In the prior art, following two modes mainly produce heavy caliber thick wall rectangular steel tube：
First way：Using the steel flat board blank material with final products fitting dimensions, using bender by its bending, pass through
Rolling closing, joint welding, welding and aligning shaping, ultimately form heavy caliber thick wall type rectangular steel tube.Production is big in this way
Bore rectangular steel tube, due to bender once can only folding square steel pipe a side, and a steel pipe can only be produced every time,
Production efficiency is not high；In addition, the steel pipe that this mode produces, even if through aligning shaping, each face of rectangular steel tube also occurs
The phenomenon of different degrees of torsional deformation, cause rectangular steel tube internal stress uneven, influence square tube quality.
The second way is：First by steel band crimped, pipe is welded into, then pipe is squeezed into square tube, this mode will
By pipe crimped and pipe pressure side twice production process, its complex manufacturing, numerous using equipment, production cost is higher；
And when pipe is being squeezed into square tube, because the crushing resistance power of pipe is larger, it is larger to produce the mechanical energy of consumption, production efficiency
It is relatively low.
Also there are some equipment that steel plate is rolled to, rolled over groove in the prior art, these equipment lack quantity-produced equipment,
Continuously steel plate can not be made to form square tube by flanging；And this equipment is when in use, the distance of flanging wheel uses in its rolling mechanism
The mode of manual adjustment width, the speed that it is adjusted is slower, and the range accuracy after adjustment is poor, it is impossible to adapts to square tube continuous production
The production of line needs.
The content of the invention
Steel band is disposably rolled to, is welded into the special equipment of square tube, using by steel coil strip in the prior art, lacking
Pressure welding is connected into pipe, then pipe is squeezed into the mode of production of square tube, there is that production process is more, and production cost is big, product quality
