Abstract
The utility model discloses a rubber lining compacting mold, which comprises a pressing head, a base, a support ring, a compacting block and a guide pole, the guide pole is fixedly mounted on the base, a through hole is provided on the compacting block, the upper part of the through hole is of taper shape, the taper upper part of the through hole is a three-degree taper hole, the lower part of the through hole is fork horn-shaped. The utility model also comprises a baffle ring which is positioned on the compacting block. Accordingly, adopting the rubber lining compacting mold, the utility model can extrude an external metal lining to increase the sticky force of internal and external metal linings and the rubber layer, thereby avoiding the falling of the rubber lining rubber layer and prolonging the service life of the rubber lining.
Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of rubber bushing compacting mould.
Background technology
Rubber bushing is the rubber elastic joint of helicopter tail rotor pitch-change-link, has characteristics simple in structure, that the damping sound insulation value is good.Rubber bushing 1 is formed by rubber layer 13 sulfurations of interior metal lining 11, outer metal lining 12 and the two therebetween, and Fig. 1 is the rubber bushing structure chart.
Rubber bushing in use, the operation of pitch-change-link drives outer metal lining and does the displacement motion, rubber layer one side in the middle of the inside and outside metal lining is subjected to tension, the opposite side compression chord, under the stress effect that changes repeatedly, rubber layer easily breaks away from from the abutting edge with inside and outside metal lining, and moment overload can cause rubber layer tension one layback stress greater than the rubber tension limit, chemical bond between rubber molecule is damaged, form microfissure, use back crackle diffusion repeatedly, cause rubber layer cracked, finally cause rubber sleeve damage to lose efficacy.For avoiding occurring above-mentioned condition, need to use the external metal lining of mould to push, make the rubber layer in the middle of the inside and outside metal lining produce certain pre-compression deformation that squeezes, to reach the purpose of the bonding force that increases inside and outside metal lining and rubber layer, thereby prolong the service life of product, but present industrial mould can not satisfy the processing request that this squeezes the technology that contracts.
The utility model content
The purpose of this utility model provides a kind of rubber bushing compacting mould, this compacting mould externally metal lining pushes, increase the bonding force of inside and outside metal lining and rubber layer, avoid the rubber bushing rubber layer to come off, thereby prolong the service life of rubber bushing.
For achieving the above object, the utility model provides a kind of rubber bushing compacting mould, comprise pressure head, base, support ring, squeeze contract piece and guide pillar, described guide pillar is fixedly mounted on the described base, the described piece that contracts that squeezes is provided with through hole, described through hole top is taper, and the conical upper of described through hole is 3 degree taper holes, and described through hole bottom is a toroidal.
The utility model also comprises baffle ring, and described baffle ring is positioned at described squeezing on the piece that contracts.
Therefore, the utility model adopts above-mentioned rubber bushing compacting mould, and externally metal lining pushes, and increases the purpose of the bonding force of inside and outside metal lining and rubber layer, avoids the rubber bushing rubber layer to come off, thereby prolongs the service life of rubber bushing.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of rubber bushing;
Fig. 2 is the structural representation of the utility model rubber bushing compacting mould embodiment duty;
Fig. 3 is for squeezing the structure for amplifying schematic diagram of the piece that contracts among the utility model rubber bushing compacting mould embodiment.
The specific embodiment
Embodiment
Fig. 2 is the structural representation of the utility model rubber bushing compacting mould embodiment, as shown in Figure 2, comprise base 21, support ring 22, squeeze contract piece 23, guide pillar 24 and pressure head 25, in squeezing compression process, load on pressure head 25 upper surfaces by electronic tensile machine, rubber bushing 1 is carried out compressing to bottom offset.Guide pillar 24 is fixedly mounted on the base 21, under the positioning and guiding effect of guide pillar 24, make rubber bushing 1 in squeezing compression process, its central axis can not depart from rubber bushing compacting mould and squeeze the segment axis that contracts, avoid occurring squeezing the inhomogeneous or serious overproof situation of axiality of the amount of contracting, guarantee the form and position tolerance of rubber bushing in whole crowded compression process.Squeeze the piece 23 that contracts and be provided with through hole 27, through hole 27 tops are taper, the conical upper of through hole 27 is preferably 3 degree taper holes in the present embodiment, little tapered configuration makes rubber bushing slowly transit to and squeezes the middle qualified size part of the piece that contracts, through hole 27 bottoms are toroidal, and the toroidal of through hole 27 bottoms is the wide-angle opening, make rubber bushing 1 can fall smoothly after crowded contracting, rubber bushing after crowded the contracting increases the bonding force of inside and outside metal lining and rubber layer, has prolonged the service life of rubber bushing.
The utility model also comprises baffle ring 26, and baffle ring 26 is positioned at and squeezes on the piece 23 that contracts, and avoids rubber bushing 1 intermediate projections accumulation in squeezing compression process, causes product defective.
Therefore, the utility model adopts above-mentioned rubber bushing compacting mould, and externally metal lining pushes, and increases the bonding force of inside and outside metal lining and rubber layer, avoids the rubber bushing rubber layer to come off, thereby prolongs the service life of rubber bushing.
It should be noted that at last: above embodiment is only in order to explanation the technical solution of the utility model but not limit it, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solutions of the utility model.
