The metal framework comprises an outer wrapping metal layer formed by folding an elastic metal sheet, the outer wrapping metal layer comprises an upper layer, a lower layer and elastic covered edges, and the upper layer and the lower layer are connected by the elastic covered edges. A cladding cavity with openings formed in the lateral sides is formed between the upper layer and the lower layer of the outer wrapping metal layer, the buffer body is filled in the cladding cavity, and the openings in the lateral sides between the upper layer and the lower layer of the outer wrapping metal layer are meshed with each other in a rivet connection mode. Compared with the prior at, the spring washer has the advantages of being good in abrasion resistance and damping performance and long in service life.
Description
Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of resilient pad.
Background technique
Pad is used widely at mechanical field as a kind of conventional fasteners; Traditional pad has rubber sheet gasket, or metallic shim; Rubber sheet gasket has good elastic performance, but wear no resistance, though the metallic shim wear resistance is good, but damping performance relatively a little less than, on some locking and demanding machines of damping property, on the one hand so that locking element (such as screw bolt and nut etc.) have good coupling mechanism force, have on the other hand bumper and absorbing shock, prevent that locking element from getting loose, traditional all can't well meet the demands; For this reason, people will add elastic material in the metallic shim, with wear resistance and the damping performance of raising pad, but because the combining structure of metallic shim and elastic material is unreasonable, still have the defective that working life is short and damping effect is poor.
Summary of the invention
For the deficiency that prior art exists, it is a kind of simple in structure that the purpose of this utility model is to provide, the resilient pad that wear-resisting property and damping performance are good.
For achieving the above object, the utility model provides following technological scheme: a kind of resilient pad, comprise the buffer body that metal frame and elastic material are made, it is characterized in that: described metal frame includes the kalamein layer that elastic sheet metal is folded to form, the kalamein layer comprises upper and lower layer and the elasticity bound edge that connects upper and lower layer, form the coating cavity that side has opening between the upper and lower layer of kalamein layer, be filled with described buffer body in the coating cavity, the side openings between the upper and lower layer of described kalamein layer is through riveting mutual interlock.
By adopting technique scheme, adopt the folded metal sheet to coat buffer body and form resilient pad, limit section has the elasticity bound edge, improved the elasticity of resilient pad, and opening portion adopts the riveted joint interlock, the sealing of resilient pad outside, and the elastic material edge portion is coated in the metal layer fully on the one hand, contact plane is metal layer, wear resistance is good, and impurity is difficult for entering in the resilient pad on the other hand, and the buffer body edge portion is in inside, do not suffer a loss, improved the working life of pad.
The utility model further is set to: it is male and fomale(M﹠F) that the upper and lower layer of described kalamein layer is positioned at coating cavity one sidewall, and described buffer body is the Expanded graphite packing ring, the Expanded graphite packing ring with upper and lower layer convex surface contact, with the concave surface formation gap of upper and lower layer; The thickness of described graphite gasket is 4-6mm.
By adopting technique scheme, buffer body adopts the setting of Expanded graphite packing ring, graphite has good wear-resisting and cushioning effect, and when resilient pad is heated, middle buffer body easily expands, buffer body and coating cavity have the gap, to a certain extent, can eliminate the volume that expands and produce, the buffer body of avoiding expanding struts the kalamein layer, improves the working life of resilient pad, and this gap also can be used as resilient pad when the locking element locking operation simultaneously, certain locking elastic operation space is provided, improves coupling mechanism force; Graphite gasket thickness adopts 4-6mm that good buffer effect is set.
The utility model further is set to: the coating cavity male and fomale(M﹠F) of described kalamein layer is that the waveform face forms.
By adopting technique scheme, buffer body and coating cavity sidewall contact are reliable.
This practicality newly further is set to: described elasticity bound edge is the evagination circular shape.
By adopting technique scheme, the working life of improving resilient pad.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the resilient pad structural representation of the utility model specific embodiment;
Fig. 2 is the A part partial enlarged drawing of Fig. 1.
Embodiment
Referring to accompanying drawing 1 and Fig. 2, the disclosed a kind of resilient pad of the utility model, comprise the buffer body 2 that metal frame 1 and elastic material are made, described metal frame 1 includes the kalamein layer that elastic sheet metal is folded to form, the kalamein layer comprises upper and lower layer 11,12 and the elasticity bound edge 13 that connects upper and lower layer 11,12, and elasticity bound edge 13 is the evagination circular shape; Form the coating cavity that side has opening between the upper and lower layer 11,12 of kalamein layer, be filled with described buffer body 2 in the coating cavity, the side openings between the upper and lower layer 11,12 of described kalamein layer is through riveting mutual interlock.Adopt the folded metal sheet to coat buffer body and form resilient pad, limit section has the elasticity bound edge, has improved the elasticity of resilient pad, and opening portion adopts the riveted joint interlock, the sealing of resilient pad outside, the elastic material edge portion is coated in the metal layer fully on the one hand, and contact plane is metal layer, and wear resistance is good, impurity is difficult for entering in the resilient pad on the other hand, the buffer body edge portion is in inside, does not suffer a loss, and has improved the working life of pad.
It is male and fomale(M﹠F) 14 that the upper and lower layer 11,12 of described kalamein layer is positioned at coating cavity one sidewall, and described buffer body 2 is the Expanded graphite packing ring, and the Expanded graphite packing ring contacts with the convex surface of upper and lower layer 11,12, with the concave surface formation gap of upper and lower layer 11,12; The thickness of described graphite gasket is 4-6mm.Buffer body 2 adopts the setting of Expanded graphite packing ring, and graphite has good wear-resisting and cushioning effect, certainly also can adopt the rubber setting, but rubber abrasive-resistance is poor, easily in its pilot hole place wearing and tearing, and aging easily, so the utility model preferentially adopts the Expanded graphite setting; And when resilient pad is heated, middle buffer body easily expands, buffer body and coating cavity have the gap, to a certain extent, can eliminate the volume that expands and produce, the buffer body of avoiding expanding struts the kalamein layer, improve the working life of resilient pad, this gap also can be used as resilient pad when the locking element locking operation simultaneously, and certain locking elastic operation space is provided, and improves coupling mechanism force; Graphite gasket thickness adopts 4-6mm that good buffer effect is set.
For further improving cushioning effect, the coating cavity male and fomale(M﹠F) 14 of described kalamein layer forms for the waveform face.Buffer body and coating cavity sidewall contact are reliable.
