Abstract
The invention belongs to the technical field of heat conducting cushioning gaskets, and particularly relates to a heat conducting cushioning pressure pad of a hot press, which is used during the operation and production process of wood decorative sheet processing devices. The technical scheme adopted by the invention is that the heat conducting cushioning pressure pad comprises a heat conducting mechanism and silicon sheets stuck to two sides of the heat conducting mechanism. The heat conducting mechanism comprises a whole metal heat conducting substrate, a plurality of heat absorbing units and a plurality of heat releasing units. The heat absorbing units and the heat releasing units are separately arranged on two sides of the whole metal heat conducting substrate. The heat conducting plates of the heat conducting cushioning pressure pad adopt whole structures, no cross points exist on the heat conducting plates, the phenomenon that heat conducting plates are broken due to mutual extrusion is avoided during the high-pressure operation period of the device, and the heat conducting cushioning pressure pad has the characteristics that the service life is long, and since the flatness is high, the heat conducting temperature is uniform, the heat transfer speed is high, the temperature difference is small, and the heat conducting effect is good.
Description
Technical field
The invention belongs to thermal conductance buffering spacer technical field, particularly relate to a kind of flat-bed press equipment, purposes in wood industry
Dalle, electronics, fabrication pressing facing overlay film process equipment run the hot press heat-conducting buffer pressure pad in producing.
Background technology
Reinforced composite floorboard, wood mould pressing floor, multi-layer solid wood floor, bamboo flooring, furniture timber, plane is included at timber wood-based plate
Card, building template and thick china etc. overlay finish coat during, in order to prevent plate surface hot-spot or local overcooling
And affect wood-based plate surface quality, and between heating platen and steel plate, it being provided with one layer of liner, i.e. heat-conducting buffer pressure pad, this heat conduction is delayed
Punching press paves the effect of compensator or trimmer pressure and conduction of heat, can make up when pressurized template (steel plate) and hot plate pressurized inconsistent and
The pressure that sheet metal thickness tolerance is caused is uneven, temperature is irregular and affects the phenomenon of wood-based plate surface quality.Therefore timber people
Make during plate facing overlays and must use heat-conducting buffer pressure pad.By retrieval:
The heat-conducting buffer pressure pad of British patent WO9613376 (applicant: Marathon company) is state-of-the-art in the world today
Product.Its structure is: the radial direction yarn of pressure pad is multiply brass wire, and weft yams is silicone rubber parcel annealing copper wire, radially yarn
Line and weft yams are woven into net by the oblique string of herringbone；The defect of this kind of product existence is: radially has with broadwise junction and intersects
Point is pressurized maximum position, when equipment work runs to maximum pressure, is easily generated and radially extrudes mutually with broadwise, during use
The many places copper wire that fractures is caused to be scattered, impact buffering resilience, use certain time limit gel coated line to cause and come off, reduce buffering resilience
Property, another radially copper cash thermal conductive contact point area is the least, and heat conduction amount is low, and when pressurized, deflection is very big, loses resilience effect, thus
Reduce service life.Based on these problems:
Chinese Patent Application No. is 981024541.3, the application for a patent for invention of Publication No. CN1240165A then discloses one
Keyboard type heat-conducting buffer pressure pad.Constitute the structure of this heat-conducting buffer pressure pad by radially and broadwise use roll bending after metal forming, press
The weaving method of wire screen is woven into the wire netting of certain specification and silicone rubber injects composition between metal forming.This structure
Although heat-conducting buffer pressure pad has (1), radial direction is that face contacts with the point of intersection of broadwise, and rubber is with metal forming contact stress relatively
Little, rubber deformation amount changes according to pressure size, is not likely to produce permanent deformation；(2), rubber radially and broadwise metal forming it
Between, difficult drop-off；(3), radially and broadwise metal forming is heat carrier, heat transfer temperature is fast, the temperature difference is little, homogeneous temperature and thermal conductivity
High；(4), only have rubber to be compressed when using, play elastic reaction, the advantages such as resilience scope is wide.But due to this heat-conducting buffer pressure pad
The heat-conducting plate of structure is the braiding structure radially constituted with broadwise metal forming, therefore there is problems in that one, constitutes heat-conducting plate
The metal forming that weaves of radial direction and broadwise after the extruding being repeated continuously, there will be loosening of braiding again, and cause overall knot
Structure loose, affects its service life；Its two, owing to the metal forming of braiding superposition does not has elasticity, therefore overall heat-conducting buffer
The elastic performance of pressure pad is poor, the heat-conducting effect that impact is overall；Its three, be difficult to unanimously due to metal forming through, broadwise elasticity,
During braiding its entirety flatness it is difficult to ensure that, thus affect buffering heat-conducting effect.
Summary of the invention
It is an object of the invention to provide a kind of overall heat transfer, good and length in service life the hot press heat conduction of elastic effect is delayed
Punching press pad.
To achieve these goals, the technical solution used in the present invention is:
A kind of hot press heat-conducting buffer pressure pad, its structure is made up of heat-conducting mechanism and the silica gel piece being affixed on its both sides；Its feature exists

Into a single integrated structure silica gel piece connecting hole；The top that described strip is convex curved be exposed to described silica gel piece outside formed heat absorption or
Heat releasing unit sheet；
Constitute convex curved of the strip protruding from described metal heat-conducting substrate both sides of described heat absorbing units and heat releasing unit
Arrange for equal in width interval；
Described heat absorbing units and heat releasing unit are that to be correspondingly arranged in the top of described metal heat-conducting substrate both sides be arc
Hollow convex bucket constitute, the arc top of this hollow convex bucket be exposed to described silica gel piece outside formed neither endothermic nor exothermic dice；
The hollow convex bucket protruding from described metal heat-conducting substrate both sides constituting described heat absorbing units and heat releasing unit is
Width interval is arranged；
The barrel of described hollow convex bucket is provided with the silicone rubber of described metal heat-conducting substrate two sides through high temperature vulcanized
Form the silica gel piece connecting hole of integrative-structure；
Described silica gel piece connecting hole is arranged on the metal heat-conducting substrate between described hollow convex bucket.
Hot press heat-conducting buffer pressure pad provided by the present invention compared with the existing technology, has the advantage that
One, is overall structure owing to constituting the heat-conducting plate of this hot press heat-conducting buffer pressure pad, does not has cross point, this buffering pressure
Pad, does not only have heat-conducting plate mutual extrusion fracture phenomenon during equipment high-voltage operation and has the spy of length in service life
Point, the most also because of its flatness height make it have heat conduction homogeneous temperature, heat transfer is fast, the temperature difference is little and the feature of good heat conduction effect；Its
Two, be through the hollow convex bucket that curved of excess convexity or top are arc owing to constituting the heat-conducting unit of this heat-conducting plate, this curved or
