Abstract
The invention particularly provides a flanging welded cylinder manufacturing method, and solves the problem in the conventional flanging welded cylinder that the flanging process is troublesome, the maintenance is time-consuming and labor-consuming, and the cost is higher. A roller cover is sleeved at an upper roller or a lower roller of a plate rolling machine; a circular roller cover groove coaxially arranged with the roller cover is formed on the outer surface of the roller cover; two end parts of the inner surface of the roller cover are arranged into inner conical surfaces; taper sleeves are arranged at two ends of the roller cover; expansion and contraction seams are formed on the side wall of the taper covers; axial bolts are uniformly distributed and screwed between the taper covers and the end surface of the roller cover; after the bolts are rotated to the roller cover and fixed with the upper roller or the lower roller, a steel plate flanged extends into a part between the upper roller and the lower roller, the steel plate at the flanged part is inserted into the roller cover groove, and the plate rolling machine drives the lower roller or the upper roller to rotate so as to roll the steel plate. In the invention, special equipment is not required, the functions of the conventional equipment are unchanged, the plate rolling principle is simple, the structure is compact, the operation is reliable, the maintenance is easy, the improvement cost is low, and the performance is reliable.
Description
Technical field
The present invention relates to mechanical molding's processing method, be specially a kind of manufacturing approach of flange welding cylindrical shell.
Background technology
Perhydro strong convection bell type annealing furnace table base heat shield is a kind of in-flanges welding tube structure; Its flange requires vertical with barrel; How to guarantee the limit of having rolled over vertical with barrel all the time in the roll bending process be a key; Adopt at present special-purpose flange equipment to carry out flange, exist technology loaded down with trivial details, safeguard and waste time and energy and the cost problem of higher.
Summary of the invention
The present invention exist when solving existing flange welding cylindrical shell flange technology loaded down with trivial details, safeguard and waste time and energy and the cost problem of higher, a kind of manufacturing approach of flange welding cylindrical shell is provided.
The present invention adopts following technical scheme to realize: the manufacturing approach of flange welding cylindrical shell; Comprise blanking, flanging, roll bending, welding four procedures, the step of roll bending is following: on the top roll of veneer reeling machine or lower roll, be with roller shell, the roller shell outer surface has the circular roller shell groove coaxial with it; And the both ends of roller shell inner surface are set to inner conical surface; The two ends of roller shell are equipped with outer surface and cooperate with inner conical surface and closely be enclosed within the tapered sleeve on top roll or the lower roll, and the tapered sleeve sidewall has expansion or contraction joints, and are uniformly distributed with between the end face of tapered sleeve and roller shell and are screwed with axial bolt; After swivel bolt to roller shell and top roll or lower roll are fixing; Steel plate behind the flanging is stretched between top roll or the lower roll, and the steel plate at flanging place inserts in the roller shell groove, and veneer reeling machine drives lower roll or top roll rotates the roll bending of realizing steel plate.This roll bending method does not change the function of existing veneer reeling machine, and principle is simple, reliable operation, has significantly reduced cost, exist when having overcome existing flange welding cylindrical shell flange technology loaded down with trivial details, safeguard and waste time and energy and the cost problem of higher.
The present invention does not need special equipment and does not change the function of existing equipment, and the roll bending Principle of Process is simple, compact conformation, reliable operation, be easy to safeguard, has that improvement cost is low, the advantage of dependable performance.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1-roller shell, 2-roller shell groove, 3-tapered sleeve, 4-bolt.
The specific embodiment
The manufacturing approach of flange welding cylindrical shell; Comprise blanking, flanging, roll bending, welding four procedures, the step of roll bending is following: on the top roll of veneer reeling machine or lower roll, be with roller shell 1, roller shell 1 outer surface has the circular roller shell groove 2 coaxial with it; And the both ends of roller shell 1 inner surface are set to inner conical surface; The two ends of roller shell 1 are equipped with outer surface and cooperate with inner conical surface and closely be enclosed within the tapered sleeve 3 on top roll or the lower roll, and tapered sleeve 3 sidewalls have expansion or contraction joints, and are uniformly distributed with between the end face of tapered sleeve 3 and roller shell 1 and are screwed with axial bolt 4; After swivel bolt 4 to roller shell 1 is fixed with top roll or lower roll; Steel plate behind the flanging is stretched between top roll or the lower roll, and the steel plate at flanging place inserts in the roller shell groove 2, and veneer reeling machine drives lower roll or top roll rotates the roll bending of realizing steel plate.In the practical implementation process, the width of roller shell groove 2 and steel plate thickness coupling, the degree of depth of roller shell groove 2 is slightly larger than the size of flange.
By calculating development size blanking steel plate, press the flange size then earlier, when assembling on the top roll that is fixed on veneer reeling machine to roller shell 1 at the folding brake upper hem; Be placed on following two rollers of veneer reeling machine adjustment top roll position the steel plate flange of flanging up; Insert flanging in the roller shell groove 2; Be rolled into tubular by roll bending technology, last butt welding realizes the making of one-sided in-flanges welding cylindrical shell.
When making bilateral in-flanges welding cylindrical shell, the quantity of the roller shell groove 2 on the roller shell 1 is two.
When making one-sided flanging welding cylindrical shell, the quantity of roller shell 1 is two, and correspondence is fixed on the veneer reeling machine lower roll, and the steel plate flange of flanging inserts in the roller shell groove 2 down during roll bending.
When making bilateral flanging welding cylindrical shell, then the quantity of the roller shell groove 2 of roller shell 1 is two on the veneer reeling machine lower roll.
Claims (1)
