Abstract
The utility model relates to a molding device for a blade of an axial flow fan. The molding device for the blade of the axial flow fan comprises a blade-molding upper mold and a blade-molding lower mold. Both the blade-molding upper mold and the blade-molding lower mold are formed through a method that a plurality of surface rib plates in different sizes are welded on a connecting plate, reinforcing ribs are welded between the surface rib plate on one side of each mold and the connecting plate and between the surface rib plate on the other side of each mold and the connecting plate, and positioning pins are arranged between the blade-molding upper mold and the blade-molding lower mold. Compared with the prior art, the molding device for the blade of the axial flow fan has the advantages that cost is low, the structure is simple, the design is reasonable and processing is simple and convenient; due to the facts that the sections of the molds are designed completely according to theoretical molded lines of the blade, and a hot press molding method is adopted in the molding device, rebound is eliminated, the molded lines of a blade blank can completely meet the requirements of designed theoretical molded lines, processing cycle is effectively shortened, and work efficiency is improved.
Description
Technical field
The utility model relates to the axial flow blower field, particularly a kind of Axial Fan Blades shaped device.
Background technology
Core component as blower fan, the vane type line precision of blower fan plays vital effect to the blower fan overall performance, the vane type line of axial flow blower is because its curved surface complex forms, make its machining accuracy, process-cycle and processing cost become Focal point and difficult point in the blower fan manufacturing, at present, one of the blade forming method of axial flow blower is the whole mold of stopping, process vane type line by numerical control machine tool, die mould is realized the blade forming of axial flow blower on forcing press, on heat extruder, blade material is squeezed into the identical section bar of blade profile shape, the shortcoming of this method is, the fabrication cycle of mold is long, and processing cost is high; Another is the method with mechanical distortion, with clamp clamps blade two ends or blade is divided into some sections clamps two ends to blade blank one torsional moment, make blade produce torsional deformation, make the axial-flow fan blade that torsional angle is arranged between each cross section of airfoil type, the shortcoming of this method is that the formed precision of blade is lower.
Summary of the invention
The purpose of this utility model provides the Axial Fan Blades shaped device that a kind of cost is low, precision is high, simple in structure, fabrication cycle is short.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of Axial Fan Blades shaped device, comprise blade forming patrix and blade forming counterdie, described blade forming patrix and blade forming counterdie are welded on gusset piece by the gluten plates of the different sizes of polylith and form, and the gluten plate of both sides respectively and be welded with reinforcement between the gusset piece.
Be provided with alignment pin between described blade forming patrix and the blade forming counterdie.
Compared with prior art, the beneficial effects of the utility model are:
A kind of Axial Fan Blades shaped device, have the advantages that cost is low, simple in structure, reasonable in design, processing is easy, because each cross section of mould is taken from the theory shaped wire of blade fully, again because the utility model adopts hot-forming, and then eliminated resilience, make the bad molded line of blade hair satisfy the theory shaped wire requirement of design fully, effectively shortened the process-cycle, improved operating efficiency.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further specified:
As depicted in figs. 1 and 2, a kind of Axial Fan Blades shaped device of the utility model, comprise blade forming patrix 1 and blade forming counterdie 2, blade forming patrix 1 is welded on gusset piece 3 with blade forming counterdie 2 by the different big or small gluten plates 6 of polylith and forms, the gluten plate 6 of both sides respectively and be welded with reinforcement 4 between the gusset piece 3 is provided with alignment pin 5 between blade forming patrix 1 and the blade forming counterdie 2.
During assembly unit the utility model, at first draw central datum line at gusset piece 3, mark the relevant position of each gluten plate 6 and carry out basic point at this straight line, then each gluten plate 6 is welded on respectively on the gusset piece 3 according to own corresponding radius, in the welding process align with central datum line in the sideline, center of attention assurance gluten plate 6, the corner angle of buffed surface gusset 6 after assembly welding is finished respectively with blade forming patrix 1 and blade forming counterdie 2, make its rounding off, each gluten plate 6 is polished by unified benchmark in the bruting process, in order to avoid cause the deviation of molded line, after finishing, assembly unit is fixed piece 6 of each gluten plates, and be welded with reinforcement 4 at the gluten plate 6 of both sides with gusset piece 3 places, increase mould strength, working face connects on blade forming patrix 1 and the forcing press, blade forming counterdie 2 lies on the forcing press workbench, adjust blade forming counterdie 2 positions, after the pedestal directrix of blade forming patrix 1 and blade forming counterdie 2 and sideline are all aligned, prevent play with pressing plate fixed blade moulding counterdie 2.
When using the utility model, at first the moving vane blank is heated to about 900 ℃, then be placed on the blade forming counterdie 2, and the central datum line that guarantees the installation reference line of blade and blade forming counterdie 2 align after opening pressure machine again, compacting is after the blade cooling, dowel hole 7 places welding alignment pin 5, then carry out the die mould of follow-up same model moving vane, forcing press will keep the die mould certain hour during die mould, in case moving vane when cooling deformation effect vane type line precision, then blade is taken out in release, and the blade die mould is finished at this point.
Above described only be basic principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
