Description
The utility model relates to the conical tube shaped device, is specially adapted to the moulding of the conical belly pipe of blast furnace.
At present, blast furnace belly pipe shaped device adopts the repeatedly equipment of moulding of segmentation more.The blast furnace belly pipe divides two sections moulding.Generally be that one section of major diameter shapes with awl roller bed with the major part of blast furnace belly pipe, the microcephaly is that another section of minor diameter is divided into several lobes, takes single-lobe thermoforming mold press molding, then, and the assembly welding global formation.The problem of the blast furnace belly pipe of this device moulding is: its surperficial weld seam is more, and one annular weld seam and multiple tracks longitudinal seam are generally arranged, so orthopedic difficulty is bigger during integral assembly welding, geometric accuracy is difficult to guarantee; Simultaneously, molding procedure is more, and difficult forming, consume material, man-hour are more.
The purpose of this utility model is a kind of conical tube shaped device that designs at the above-mentioned existing problem of blast furnace belly pipe shaped device, and it can make the blast furnace belly pipe surface of moulding that longitudinal seam is only arranged one, and is orthopedic simple, the geometric accuracy height; Molding procedure is few, shortens Production Time, saves raw material.
The utility model is finished like this.
The conical tube shaped device is made up of the pressure mechanism of loose tool in loose tool and the push-and-pull on loose tool, the taper shape under the taper shape, it is characterized in that the corresponding central angle θ of circular arc on the upper and lower loose tool cross section is 110 °～130 °; Arc radius r on the loose tool cross section up and down
θ=r (1-(5～15%)); The intermediate member that last loose tool is connected with pressure mechanism is by the fixed board of upper cover plate, lower cover, an end and the movable riser of the other end, and drift is formed with following drift on the fixed coupling unit; Conical tube is body formed to be to adopt to press the asymptotic manufacturing process of conical tube shaping bus to realize.
The utility model is described in further detail with an embodiment and accompanying drawing below.
Fig. 1 is the utility model conical tube shaped device perspective view.
Fig. 2 is plane of the present utility model master's TV structure schematic diagram.
Fig. 3 is blanking and the line drawing method schematic diagram that utilizes the utility model compacting conical tube.
Fig. 4 is the structural representation that utilizes the conical tube of the utility model compacting.
The conical tube shaped device is made up of the pressure mechanism M of loose tool (2) in loose tool (2) and the push-and-pull on loose tool under the taper shape (1), the taper shape, direction shown in the arrow is loose tool (2) direction of motion in the pressure mechanism M push-and-pull, characteristics be on upper and lower tire major part or the horizontal cross section of microcephaly circular arc the value range of corresponding central angle θ be 110 °～130 °; Arc radius r on upper and lower loose tool major part or the microcephaly's cross section
θ=r (1-(5～15%)), wherein, r is the conical tube radius (internal diameter) after the moulding, from following formula, formed arc radius r on the loose tool cross section up and down as can be seen
θLittler than the conical tube radius (internal diameter) after the moulding, this is because steel round metal Taper Pipe will produce a certain amount of resilience after compacting, makes caliber become big.Utilize above-mentioned empirical equation of the present utility model, after compacting is finished, can obtain satisfied dimensional accuracy; The intermediate member that last loose tool (2) is connected with pressure mechanism M is by loam cake steel plate (3), lower cover steel plate (4), the fixedly Steel vertical plate (5) of one end and the movable Steel vertical plate (6) of the other end, and drift (7) and following drift (8) are formed on the fixed coupling unit, following loose tool (1) is fixed on the pedestal (9), makes pressure mechanism M and upper cover plate (3) affixed by connecting plate (14); Conical tube is body formed to be to adopt to press the asymptotic manufacturing process of conical tube moulding bus to realize.Its method is: (1) at first makes loose tool up and down.Arc radius r on the cross section of loose tool up and down of present embodiment
θ=r (1-10%), r is the cross section real radius of the conical tube that will make.The corresponding central angle θ of circular arc on the loose tool cross section=120 ° up and down; (2) according to the actual size blanking of the conical tube that will make; (3) with fan-shaped blanking plane by 12 five equilibriums draw bus OA, OB, OA ', the OB ' of conical tube ...(4) compacting.The fan-shaped blanking plane of the bus finished is sent into up and down between the loose tool, and allowed the bus of loose tool (2) aim at the bus that draws in the hinge shape blanking of laying equal stress on, and left-right symmetry is suppressed bus OA, OA ' successively; 0B, OB '; Until compacting center bus OP.Repeat said process, fan-shaped blanking plane is rolled into taper barrel gradually, and will go up loose tool (2) and lower cover (4) the encirclement formation cone affixed with last loose tool (2).Because the formed circular arc line NAB in fan-shaped blanking plane ... P ... the pairing circular arc line in expansion plane of cone that loose tool forms is long about the B ' A ' N ' ratio, so utilize the seam crossing of the conical tube that the utility model suppresses to have one to form the parallel coincidence limit of bus with conical tube, but when conical tube from last loose tool (2) when unloading, the process that unloads is: the flexible handle (10) that will be slidingly matched with upper cover plate (3) and lower cover (4) at first, (11) lay down, and then unload drift on the fixed coupling unit (7) and following drift (8), the movable riser (6) that is slidingly matched with upper cover plate (3) and lower cover (4) is extracted out, at last, conical tube (12) is extracted out from lower cover (4) and last loose tool (2).Because the resilience of round metal Taper Pipe disappears the coincidence limit of seam crossing, thereby obtains satisfied circular cone body weld seam (13).Again weld seam (13) is burn-on, just obtain the more accurate circular cone body of geomery.
Another characteristics of the present utility model are pairing central angle θ of the circular arc on the upper and lower loose tool cross section=120 °.
Last characteristic of the present utility model are arc radius r on the upper and lower loose tool cross section
θ=r (1-10%).
The utility model is simple in structure, flexible operation, owing to have only longitudinal seam one after the conical tube moulding, so control the body formed quality of conical tube easily, conical tube global shape dimensional accuracy height.Molding procedure is simple, saves raw material and man-hour, the efficiency height.
