Background technology
Large-scale EVA foaming machine in generally using at present, no matter import or domestically produced machine, its hierarchy is all comprised of vertical riser and the demixing plate being fixed thereon, when machine is during in die opening state, because the horizontal stripe of heating plate can directly contact with demixing plate, and demixing plate is without the design of vibration damping aspect, so, between heating plate and demixing plate, can form strong shock, therefore, this structure will exist and impact the shortcoming large, machine vibration is large, noise is large, the fatigue life of heating plate horizontal stripe is low.
In addition, applicant applied for " a kind of layering vibration absorber that is applied to small-sized EVA foaming machine " (patent No.: 201020265272.1) on July 14th, 2010, the layering vibration absorber of setting forth in this patent is not only simple in structure but also be only applicable to the small-sized EVA foaming machine that impact is little, because large-scale EVA foaming machine can produce stronger impact in running, so the inapplicable this layering vibration absorber simple in structure of large-scale EVA foaming machine.
Summary of the invention
In order to make up above-mentioned heating plate horizontal stripe, when directly contacting with demixing plate, existing impact is large, machine vibration large, low defect fatigue life of heating plate horizontal stripe, the utility model provides a kind of vibration and noise reducing device being applied in large-scale EVA foaming machine, it can reduce the impact strength of the horizontal stripe of heating plate to demixing plate effectively, and can alleviate the vibration of complete machine, reduce noise, finally extend the fatigue life of oil cylinder and heating plate horizontal stripe.
In order to achieve the above object, the utility model is taked following concrete technical measures: a kind of vibration and noise reducing device being applied in large-scale EVA foaming machine, and its architectural feature is, it comprises main vibration absorber, layering vibration and noise reducing device two large divisions,
Wherein, main vibration absorber is by vertical riser, demixing plate, dive key, vibration proof mounting, parallels one, damping block, collision block and adjustment screw form, oil cylinder and the seat of honour are connected into respectively the framework of a sealing by many root posts and a plurality of nut combinations, many vertical risers by screw one respectively with oil cylinder, the seat of honour is fixedly connected, many demixing plates pass through dive key, screw three is connected on vertical riser, on the vertical riser of demixing plate bottom, by screw two, be fixed with to bear the vibration proof mounting of heating plate gravity and impulsive force, in vibration proof mounting inside, be disposed with from top to bottom adjustment screw, parallels one, damping block and collision block, demixing plate is supported on collision block.
The damping block of collision block below can play the effect of vibration damping, and damping block adopts polyurethane material to make.
Wherein, layering vibration and noise reducing device is comprised of layering vibration proof mounting, elastomer block, parallels two, shaft shoulder screw, layering vibration and noise reducing device is arranged on demixing plate, on demixing plate, be processed with step, many layering vibration proof mountings are connected on demixing plate by screw tetrad, in layering vibration proof mounting inside, be disposed with from bottom to top elastomer block, parallels two and shaft shoulder screw, the bottom of shaft shoulder screw run through layering vibration proof mounting top and with parallels two sockets, the bottom of shaft shoulder screw is finally arranged at the top of elastomer block, and heating plate horizontal stripe is supported on shaft shoulder screw.
In layering vibration and noise reducing device, elastomer block plays the effect of vibration and noise reducing, and elastomer block adopts elastomeric material to make.
When foaming process finishes, machine, by automatic die sinking, declines rapidly because cavity pressure makes heating plate, and the horizontal stripe on heating plate touches shaft shoulder screw, and shaft shoulder screw is delivered to impulsive force in elastomer block; From large range of structures, demixing plate vertically can slide along dive key in the vertical direction on riser, and the impulsive force of all heating plates finally all can be delivered on damping block by the collision block under demixing plate.The material that is rubber, damping block due to the material of elastomer block is polyurethane, this bi-material is according to its characteristic, not only can absorb strong impact but also can Powerful Rebound, thereby reach the object that alleviates complete machine oscillation, reduces noise, extends oil cylinder and heating plate horizontal stripe fatigue life.
The beneficial effects of the utility model are, it can reduce the impact strength of the horizontal stripe of heating plate to demixing plate effectively, and the vibration that can alleviate complete machine, reduce noise, finally extend the fatigue life of oil cylinder and heating plate horizontal stripe.
Below in conjunction with drawings and Examples, the utility model is illustrated further.
