Abstract
The invention discloses a manufacturing method for special-shaped steel pipes special for logistics shelves. The method includes the following technical processes that a cold-rolled strip steel or hot-rolled strip steel reel inspected to be qualified is hoisted and conveyed to an uncoiling machine of a pipe welding unit to be uncoiled, the head portion of the steel reel is dragged into a crosscut shear to be cut off, then the steel reel and a last steel reel with the tail portion cut off are welded in a butting manner, the intersect angle between the weld joint obtained after shearing and welding and the central line of the pipe welding unit is 30 degrees, and accordingly strip steel at the weld joint, a formed pipe blank and a formed steel pipe do not simultaneously enter the unit. Steel strips in butt welding is prevented from being broken apart in the storage, molding and sizing processes, and the dimensional accuracy of the fracture surface and length of steel pipes is improved.
Description
Technical field
The present invention relates to the manufacture field of steel tubes, specifically belong to a kind of manufacture method of logistics shelf special irregular steel pipe.
Background technology
At present, the technological process of production of steel tubes is as follows:
Blank preparation-material loading-uncoiling-shearing-butt welding-pinch-bin stock-pinch-smooth-shaping (garden pipe)-welding-deburring-cooling-sizing (shape tube)-correct-fly saw (cutting long chi)-collection-finishing mandrel (multiple length)-detection-bundling-mark-warehouse-in.But also exist and be easily pulled off in bin stock and shaping and Sizing Process the steel band of postwelding, steel tubes section configuration and dimensional accuracy can not guaranteed shortcomings.
Summary of the invention
The object of this invention is to provide a kind of manufacture method of logistics shelf special irregular steel pipe, avoid being pulled off in bin stock and shaping and Sizing Process the steel band of postwelding, improve the dimensional accuracy of product section and length.
Technical scheme of the present invention is as follows:
A manufacture method for logistics shelf special irregular steel pipe, includes following processing step:
1), uncoiling is carried out by the cold-strip steel through being up to the standards or hot-rolled strip steel winding handling to the uncoiler of welded pipe units, steel coil head is drawn into after carrying out crop in cross cut shears, butt welding is carried out with the truncate coil of strip in portion of a upper cut roll, shear, weld seam and welded pipe units center line after welding be 30 ° of angles of cut, make the band steel of commissure and shaping after pipe, steel pipe difference time ingress engine group;
2), for guaranteeing the continuity that welded pipe units is produced, by in pinch roll feeding cage kink case, cover storage is filled to the steel band of postwelding, steel band through the pinch roll of shaping machine set head be drawn into planisher carry out smooth after, send into the garden pipe being rolled into required specification in the roll pass of shaping machine set, through high-frequency welding, deburring, after cold rinse bank cooling, send the steel tubes being rolled into required specification in the roll pass of sizing unit, computer simulation is carried out to the roll profile of shaping machine set and sizing unit and assists hole type design, and in the operation of rolling, on-line tuning is carried out to roll shape,
3) steel tubes, after sizing is after Turkey's straightening heads is corrected, send and fly to saw the multiple length that sawing becomes user's Len req, undertaken collecting by collecting frame, bundling, and adopt high accuracy scale sawing machine to carry out off-line sawing, guarantee that product length deviation is within 0-2mm, finishing mandrel becomes the steel tubes of scale qualified rear bundling, mark, warehouse-in after testing.
For the special P shape steel tube of logistics shelf, P type pipe transverse shear stress mould is adopted to squeeze out accurate in size P type pipe product, regulate the position of left and right rotating shaft in guide groove and bar hole to regulate spacing between left and right pinch roller by push rod and screw rod, thus squeeze out accurate in size P type pipe product.
Beneficial effect of the present invention is as follows:
1) P type pipe transverse shear stress Design of Dies technology: regulate the position of left and right rotating shaft in guide groove and bar hole to regulate spacing between left and right pinch roller by push rod and screw rod, thus squeeze out accurate in size P type pipe product;
2) Pass Design Technique and on-line tuning technology are assisted in the computer simulation of logistics shelf special irregular steel pipe: by deformation process and the auxiliary hole type design of computer simulation steel tubes, determine the pass schedule of steel tubes the best, according to the fluctuation of material and supplied materials size, local pass is finely tuned in process of production, improve product cross dimensions precision;
3) logistics shelf special irregular steel pipe off-line saw technology: at present, the length variation that welded pipe units flies to saw online sawing is generally 8mm-10mm, be difficult to reach the requirement that user 0-2.5mm directly uses (save time, saving of labor, material-saving), for ensureing that product length deviation is within 0-2mm, adopt high accuracy scale sawing machine to carry out off-line sawing, guarantee product length deviation.
4) the shear centre line of cross cut shears and welded pipe units center line are 30 ° and arrange.Shear, weld seam and welded pipe units center line after welding be 30 ° of angles of cut, make the band steel of commissure and shaping after pipe, steel pipe difference time ingress engine group, avoid being pulled off in bin stock and shaping and Sizing Process the steel band of postwelding;
5) computer simulation is carried out to the roll profile of shaping machine set and sizing unit and assist hole type design, determine the pass schedule of steel tubes the best, according to the fluctuation of material and supplied materials size, local pass is finely tuned in process of production, improve product cross dimensions precision.
