Description
Technical field
The utility model relates to a kind of mould.Specifically, the pipe-reduction mold reducing metal tube end diameter is used to.
Background technology
At some special occasions, require that the diameter of metal tube one or both ends is less than its interlude.At present, the method reducing metal tube end diameter adopts traditional pipe-reduction mold one end to the identical metal tube of longitudinally each spot diameter to carry out hot extrusion to realize.Pipe-reduction mold wherein comprises base plate, top board, mould, mould emptier and press mechanism; counterdie is fixed with in the middle of described plate upper surface; counterdie there is vertical centre bore; the each point equal diameters of centre bore hypomere; centre bore epimere is lower little large bellmouth; and centre bore upper end bore is with suitable by metal tube external diameter, during the draw, inserted in centre bore from centre bore upper end by pipe lower end, receding metal.Have demoulding oil jar below base plate, the piston rod outer end of demoulding oil jar is stretched in centre bore from the lower end of described centre bore.Be connected with patrix below described top board, patrix have vertical hole, during the draw, to be stretched into from lower end, vertical hole in vertical hole by institute's metal tube upper end and offset with top board.Be connected with down pressing oil cylinder above patrix, the piston rod outer end of down pressing oil cylinder withstands on top board center.The relative both sides of top board are processed with rod aperture, all have guide post and in being slidably matched between the two, guide post lower end is all fixed on base plate in two rod aperture.During work, first heat by receding metal pipe, then exert pressure to top board and by receding metal pipe by the piston rod of down pressing oil cylinder is overhanging.When being squeezed after in tap web shape by pipe lower end, receding metal, restarting demoulding oil jar, will upwards be ejected the centre bore of counterdie by pipe lower end, receding metal by the overhanging of demoulding oil jar piston rod, thus realize the reduced of metal tube one end.Although adopt above-mentioned mould can realize reducing of metal tube bore, need down pressing oil cylinder and demoulding oil jar two oil cylinders, the oil cylinder of needs is many, and equipment investment is many, makes production cost high.Again because patrix and lower intermode are without the location-plate preventing from being out of shape by receding metal pipe, make to be managed easy flexural deformation by receding metal in draw process, like this, also need to be equipped with shaping mould, not only processing step is many, and production efficiency is low.
Utility model content
Problem to be solved in the utility model is to provide a kind of pipe-reduction mold.Adopt this pipe-reduction mold, production cost can be reduced, enhance productivity.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Pipe-reduction mold of the present utility model comprises base plate, bearing, mould, mould emptier and press mechanism; described bearing contains at least three pillars and top board; along base plate circumferentially, their lower end is fixed on base plate described pillar, and described top board is fixed on three pillar upper ends.There is the through hole coordinated with by draw mouth at top board center, is characterized in there is retainer plate above top board, retainer plate has vertical centre bore, has described mould in vertical centre bore.Described mould is tubulose, and there is vertical hole at its center, and each point aperture of described vertical hole epimere is equal, and described vertical hole hypomere is the first bellmouth that aperture, upper end is less than lower end.Described press mechanism contains top board and lower platen, and the relative both sides below top board are connected with backing plate.Described two backing plates are strip plate, and their a long limit is fixed on top board lower surface, and their another long limit is that free shape rests above described lower platen; There is cross carrying plate between two backing plates, the top board corresponding to cross carrying plate two ends has the first rod aperture, all having push rod in two first rod aperture and in being slidably matched between the two, push rod lower end is that free shape is placed in above cross carrying plate; Described lower platen is that free shape is placed on mould.Have two guide rods between lower platen and top board, described two guide rod upper ends are that relative shape is connected on the lower surface of lower platen, the top board corresponding to two guide rods have the second rod aperture, and two lower end of the guide rod are slip shape stretches in the second rod aperture.Lower platen center is porose, has knockout pin in hole, and knockout pin upper end and cross carrying plate lower surface offset, knockout pin lower end with offseted by pipe upper end, receding metal.
Further improvement of the utility model scheme is, described top board has second bellmouth corresponding to the first bellmouth, and the aperture, upper end of the second bellmouth equals the aperture of the first bellmouth lower end, the aperture of the second bellmouth lower end and the equal diameters of described through hole.
Further improvement project of the present utility model has location-plate between described top board and base plate, and there is rod aperture at location-plate center, penetrated in this rod aperture during work by receding metal pipe.
As can be seen from the above scheme, owing to having retainer plate above top board, retainer plate there is vertical centre bore, in vertical centre bore, have mould.Described mould is tubulose, and there is vertical hole at its center, and each point aperture of described vertical hole epimere is equal, and described vertical hole hypomere is the first bellmouth that aperture, upper end is less than lower end.Described press mechanism contains top board and lower platen, and the relative both sides below top board are connected with backing plate.Described two backing plates are strip plate, and their a long limit is fixed on top board lower surface, and their another long limit is that free shape rests above described lower platen.Having cross carrying plate between two backing plates, the top board corresponding to cross carrying plate two ends has the first rod aperture, all having push rod and in being slidably matched between the two in two first rod aperture, push rod lower end is free shape and the contacting above of cross carrying plate.Described lower platen is that free shape is placed on mould.Have two guide rods between lower platen and top board, described two guide rod upper ends are that relative shape is connected on the lower surface of lower platen, the top board corresponding to two guide rods have the second rod aperture, and two lower end of the guide rod are slip shape stretches into and the second rod aperture.Lower platen center is porose, has knockout pin in hole, and knockout pin upper end and cross carrying plate lower surface offset, knockout pin lower end with offseted by pipe upper end, receding metal.
During work, by top board, backing plate, lower platen, a downward pressure is applied to mould by hydraulic jack, while mould moves down, make metal tube upper end form taper.Then, by two push rods, cross carrying plate, a downward pressure is applied to knockout pin by down pressing oil cylinder, a downward pressure is applied by pipe upper end, receding metal again by knockout pin, make to be thrown off by the bellmouth of the tapering point of pipe upper end, receding metal and mould hypomere, thus achieve the draw processing of metal tube one end.Need an oil cylinder to compare with background technology kind is shaping respectively with the demoulding, the utility model only needs an oil cylinder, just can realize the shaping of metal tube end and the demoulding, and the oil cylinder of needs is few, thus decreases equipment investment, reduces production cost.Again owing to being provided with location-plate between top board and base plate, there is rod aperture at location-plate center, is penetrated in this rod aperture during work by receding metal pipe, avoids the flexural deformation in the middle of metal tube, does not need to be equipped with shaping mould, not only reduces processing step, also improve production efficiency.
