Abstract
The utility model belongs to the technical field of oil hydraulic forging presses, and discloses a special oil hydraulic forging press for a piston rod. The special oil hydraulic forging press for the piston rod is mainly technically characterized by comprising a tail cross beam and a master oil cylinder beam which are connected through a pull rod, wherein a slider moving along the pull rod is arranged on the pull rod; a master oil cylinder is arranged on the master oil cylinder beam; the top shaft of the master oil cylinder is connected with the slider; a block propping mold is fixed at the front end of the slider through a first oil cylinder; a workpiece insert hole is formed in the tail cross beam; a fixed mold and a movable mold corresponding to the fixed mold are arranged at one side, close to the slider, of the workpiece insert hole; the movable mold is fixed with the tail cross beam through a second oil cylinder; and a trimming mold is arranged on a side surface of the block propping mold. Before forging, a forge piece is only required to be heated at the front end part instead of wholly heated, so that heating energy is saved, and the power energy is saved due to the fact that only the head part is required to forge.
Description
Technical field
The utility model belongs to forge oil technical field of pressing machine, relates to concretely the special-purpose forge oil press of piston rod.
Background technology
In engineering machinery field, piston rod is widely used, and is determining the service life of whole engineering machinery in the quality of piston rod quality and service life.The piston rod using at present mainly contains following several: one, and foundry goods, in use, intensity is low for this piston rod, and there is oil impregnate in bar portion, and service life is low, and head and bar portion junction easily fracture; Its two, first forge head and then weld, easily cause head to fracture; Its three, with coarse fodder, by bar portion pulling, with mould, nose shape is forged, then trimming, in dead man process, need to be by the whole high-temperature heating of the body of rod, and then with pole jack, the body of rod is pulled out, not only cause the waste of the heat energy energy, also cause power source waste, production efficiency is low.
Utility model content
The technical problem that the utility model solves is just to provide the special-purpose forge oil press of large, the oil proof piston rod of piston rod intensity that a kind of production efficiency is high, save the energy, production.
For solving the problems of the technologies described above, the technical scheme the utility model proposes is: comprise the afterbody crossbeam and the master cylinder beam that by pull bar, connect, on described pull bar, be provided with the slide block moving along pull bar, on described master cylinder beam, be provided with master cylinder, the apical axis of described master cylinder is connected with described slide block, in described slip front, by the first oil cylinder, be fixed with top pier mould, on described afterbody crossbeam, be provided with workpiece jack, at workpiece jack, near described slide block one side, be provided with fixed die and the movable mold corresponding with this fixed die, this movable mold is fixed by the second oil cylinder and afterbody crossbeam, in pier mould side, described top, be provided with edger.
The special-purpose forge oil press of piston rod that the utility model provides and the method for forging piston rod, compared with the existing technology have the following advantages: one, owing to comprising afterbody crossbeam and the master cylinder beam connecting by pull bar, on described pull bar, be provided with the slide block moving along pull bar, on described master cylinder beam, be provided with master cylinder, the apical axis of described master cylinder is connected with described slide block, in described slip front, by the first oil cylinder, be fixed with top pier mould, on described afterbody crossbeam, be provided with workpiece jack, at workpiece jack, near described slide block one side, be provided with fixed die and the movable mold corresponding with this fixed die, this movable mold is fixed by the second oil cylinder and afterbody crossbeam, in pier mould side, described top, be provided with edger, before forging, only the leading section of forging need be heated to 1050 ℃---1200 ℃, do not need the whole heating of whole foundry goods, saved the heating power energy, and only need forge head, saved power source, trimming subsequently after forging, saved equipment investment, reduced taking of space, workshop, on the pier mould of top, move and edger moved to forging correspondence position after, first movable mold is opened, then will on forging, move to edger edge, then fixing movable mold, avoid edger skew to cause forging to damage, and shortened the stroke of master cylinder, saved the energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the special-purpose forge oil press of piston rod;
Fig. 2 is the structural representation from the special-purpose forge oil press of piston rod of another angular observation.
The specific embodiment
The structure of the special-purpose forge oil press of piston rod the utility model being proposed below in conjunction with accompanying drawing is described further.
As depicted in figs. 1 and 2, be the structural representation of the special-purpose forge oil press of piston rod.Its structure comprises afterbody crossbeam 2 and the master cylinder beam 3 connecting by pull bar 1, on pull bar 1, be provided with the slide block 4 moving along pull bar 1, on master cylinder beam 3, be provided with master cylinder 5, the apical axis 6 of master cylinder 5 is connected with slide block 4, front end at slide block 4 is fixed with top pier mould 8 by the first oil cylinder 7, on afterbody crossbeam 2, be provided with workpiece jack 9, at workpiece jack 9, near slide block 4 one sides, be provided with fixed die 11 and the movable mold 12 corresponding with this fixed die 11, this movable mold 12 is fixing with afterbody crossbeam 2 by the second oil cylinder 13, in pier mould 8 sides, described top, be provided with edger 14.
Before forging, only the leading section of forging 10 need be heated to 1050 ℃---1200 ℃, do not need the whole heating of whole foundry goods, save the heating power energy, and only need forge head, saved power source, after forging, trimming subsequently, has saved equipment investment, has reduced taking of space, workshop; On the pier mould of top, move and edger moved to forging correspondence position after, first movable mold is opened, then will on forging, move to edger edge, then fixing movable mold, avoid edger skew to cause forging to damage, and shortened the stroke of master cylinder, saved the energy.
Protection domain of the present utility model is not only confined to above-described embodiment, as long as structure is identical with the special-purpose forge oil press structure of the utility model piston rod, just drops on the scope of the utility model protection.
