Abstract

The utility model provides a quick mould replacing device of a horizontal rim expanding machine. The quick mould replacing device comprises an integral base, a left expanding mould assembly and a right expanding mould assembly, wherein the left expanding mould assembly and the right expanding mould assembly are symmetrically arranged on the base. An auxiliary mould replacing mechanism is arranged above the integral base. The auxiliary mould replacing mechanism comprises a support and a hoist. The support is arranged above the base and extends towards one side. The support is provided with a rail for installing the hoist. The two ends of the rail correspond to a disassembly and assembly position and a mould replacing position respectively. Limiting devices are arranged on the rail where the disassembly and assembly position and the mould replacing position are located. When one expanding mould needs replacing, six screws on the expanding mould are unscrewed, next, the expanding mould is directly lifted up to an outer position area through an electric hoist lifting hook arranged on the rail, and then the expanding mould is maintained, replaced and detected. The quick mould replacing device greatly shortens the mould replacing time, greatly reduces labor intensity of workers and enables the mould replacing time to be controlled within 20 minutes.

Description

The horizontal dilator quick die change device of a kind of wheel rim workpiece
Technical field
The utility model relates to automobile rim workpiece dilator equipment die change local mechanism, the specifically horizontal dilator quick die change device of a kind of wheel rim workpiece.
Background technology
In automotive hub production technology, have an expansion process, its basic demand is that wheel hub workpiece is carried out to expansion and the finishing in circularity, improves further its circularity.This process is used dilator to operate conventionally.The wheel rim of different patterns need to use the dilatation mold of different size, and wherein the replacing of this mould is a very thing for effort.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of wheel rim workpiece horizontal dilator quick die change device, for the auxiliary speed that improves die change.
The utility model solves the technical scheme that its technical problem adopts: the horizontal dilator quick die change device of a kind of wheel rim workpiece, comprise that Integral pedestal and symmetry are arranged on the left and right dilatation mold assembly on base, and by securing member, dilatation mold is installed in right dilatation mold assembly and left dilatation mold assembly, it is characterized in that, above described Integral pedestal, be provided with a mould auxiliary replacement mechanism, described mould auxiliary replacement mechanism comprises support and lifting cucurbit, described support is arranged on the top of base and extends to a side, on described support, be provided with the track that lifting cucurbit is installed, the respectively corresponding dismounting station in the two ends of described track and a die change station, and be all provided with stopping means on the track at dismounting station and a die change station place.
At the station place of track outer end, be provided with a support platform.
Further, described stopping means is a fixing block in orbit.
Further, described stopping means is one for automatically controlled travel switch.
The beneficial effects of the utility model are: this equipment, when needs mold exchange, unclamps 6 screws on dilatation mold, by dress electric hoist suspension hook in orbit, mould are directly winched in the station region in outside, to mold repair, change and detect.This device has shortened mould replacing time greatly, has greatly reduced workman's labour intensity, and mould replacing time was controlled within 20 minutes.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model;
Fig. 2 is the full sectional view of Fig. 1;
In figure: 1 left dilatation mold assembly, 2 right dilatation mold assemblies, 3 bases, 5 mould auxiliary replacement mechanisms, 51 supports, 52 lifting cucurbits, 53 dismounting stations, 54 die change stations, 55 support platforms.
The specific embodiment
As Fig. 1 to Fig. 2,
First, the horizontal dilator of wheel rim workpiece is such, comprises that Integral pedestal and symmetry are arranged on the left and right dilatation mold assembly on base.
Left dilatation mold assembly 1 and right dilatation mold assembly 2 have identical structure, are symmetrical arranged, and are all secondary drive.The left dilatation mold assembly of take is below elaborated as example:
Left dilatation mold assembly comprises master slider, the first oil cylinder, the second oil cylinder, pyramid, expansion piece and dilatation mold, wherein, master slider is comprised of two risers and joint pin, for fabricated structure, master slider is arranged on base 3 by line slide rail slip level, and at line slide rail place, all adopt automatic grease lubricating system, charging-up lubricant oil regularly, can realize the object of long-term stable operation.Because the weight of master slider is larger, and in process of expansion, be subject to horizontal direction, structure by this way more reasonable.
Between master slider and base 3, the first oil cylinder being installed, is quick propelling cylinder, can realize the function of fast feed, and workpiece is clamped fast.During work, the first oil cylinder in the assembly of left and right moves simultaneously, can realize the object of Fast synchronization motion.Increase work efficiency and expand precision.
Master slider central authorities are provided with the axis hole of level, axis hole forms by axle sleeve and other cartridges, and a pyramid is installed in axis hole, and so-called pyramid refers to that outer end is that cylindric the inner is the pyramid-shaped of 12 faces, outer end is wherein drive end, and the inner is working end.Pyramid outer end is connected with the piston of the second oil cylinder, on the second oil cylinder fixed installation master slider, and such the second hydraulic oil cylinder driving pyramid stretching motion.On each conical surface of pyramid, piece is expanded in one of corresponding installation respectively, for fan-shaped, between expansion piece and pyramid, by wear-resistant block, carry out wedge-like engagement, inclined-plane guiding, the life-span of mould and the precision of operation have greatly been improved, 12 expansion pieces are radial centered by pyramid and are arranged on master slider by line slide rail, and fix respectively an extension module on each expansion piece, and 12 extension modules form a cylinder.The horizontal axis of pyramid can be moved and be converted to expansion piece along the moving radially of pyramid, finally drive the diameter of extension module to change.The pyramid of two assemblies is respectively equipped with inner face center and is provided with a gauge orifice, and is provided with auxiliary standard lining bar, whether concentric detects two centrums by standard lining bar, checks the accuracy of alignment of mould.
Also comprise a mould auxiliary replacement mechanism 5, described mould auxiliary replacement mechanism comprises support 51 and lifting cucurbit 52, support is steel welding connecting structure, support 51 is arranged on the top of base and extends to one end, on support, be provided with the track that lifting cucurbit is installed, cucurbit can be moved along track in lifting, at the two ends of track, be respectively dismounting station 53 and a die change station 54, dismounting station 53 is wherein the central authorities in dilator just in time, die change station 54 places are provided with a support platform 55, conveniently keep in repair and change.On the track at dismounting station and a die change station place, be all provided with stopping means, stopping means can for mechanical position limitation or travel switch spacing.When mold exchange more, mold integral hangs out, and will expand piece detect in equipment outside, guarantees the mould and die accuracy of replacing.Whole mould replacing time was controlled in 20 minutes.
Embodiment recited above is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in protection domain as determined in the utility model claims.
