Description
Technical field
This utility model relates to honeycomb sandwich panel and manufactures field, and a kind of 90 ° of R angle honeycomb sandwich constructions are combined
The fabricating tools of plate.
Background technology
Honeycomb is the most hexagonal a kind of structural core, lightweight, intensity is high, in Aeronautics and Astronautics, track traffic and building
The field application such as decoration, household are wider.Wherein aramid paper honeycomb have lightweight, high intensity, high-modulus, fire-retardant, insulation, resistance to height
A series of Optimalities such as temperature, insulation, nontoxic, nothing is expanded with heat and contract with cold, anti-metal is tired, the high-low temperature difference of resistance to nature, low-dielectric loss
Can, it has also become the preferred core of the industries such as aircraft, bullet train, subway, light rail.
Honeycomb sandwich construction composite is that it is by 3 kinds by the composite of comb core with surfacing bonding
Stock combines, i.e. panel material, honeycomb core, adhesive.Honeycomb sandwich construction be mainly characterized by upper and lower panel
Material thickness the most identical, and the thinnest, the strength and stiffness of panel material require the highest.Its main property
Feature less sandwich density can be showed themselves in that, construction weight can be substantially alleviated；Heat conductivity is low, can be as insulation with exhausted
Hot component uses；Higher specific strength and specific stiffness, can carry out anisotropy design according to particular/special requirement and manufacture.The most long-term
Since enjoy the concern in the field such as Aeronautics and Astronautics and bullet train, especially in aircraft industry, honeycomb sandwich construction composite wood
Material is the most successfully widely used in the primary and secondary load-carrying construction part of aircraft, such as positions such as wing, fuselage, empennage and radomes.
Summary of the invention
This utility model is for overcoming the deficiencies in the prior art, and design one can make full use of honeycomb sandwich construction composite wood
The forming manufacture technique that material is excellent, the characteristic of high-strength light, thus solve honeycomb sandwich construction at track traffic applicating category
In 90 ° of R angles preparation process in, mass production difficulty, the fabricating tools of the high technical problem of defect ware rate.
For achieving the above object, design the fabricating tools of a kind of 90 ° of R angle honeycomb sandwich construction composite plates, including upper mold, under
Mould, is characterized in that: described upper mold is L-shaped, and described lower mold is L-shaped, is provided with cellular board body, described upper mold between lower mold and upper mold
The outside of right angle is provided with angle bar, described angle bar be arranged over steel plate；It is positioned at lower mold right angle below cellular board body
Inner side is provided with circular arc batten.
The outside of described lower mold right angle is provided with the straight angle.
Being embedded with countersunk head wood screw in described circular arc batten, the bottom of described countersunk head wood screw is connected with lower mold, tack wood
The top of screw is less than the arc-shaped surface of circular arc batten.
This utility model compared with the existing technology, utilizes easy machine-shaping, and the wooden die of fine-tuning partial structurtes, system
Make upper and lower mould at an angle of 90, and the inside and outside R angle of two moulds can be carried out structure optimization, change the design of right angle outside two moulds
Materials, thus ensure to prepare the honeycomb sandwich construction composite plate at a kind of 90 ° of R angles, and the size at wherein R angle is less, R >=
20mm.Solving cellular sandwich material in applications such as track traffics, 90 ° less R angle square cun sandwich composite plates cannot
A difficult problem for batch production, reduces defect ware rate in production simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of part A in Fig. 1.
Seeing Fig. 1～Fig. 2, wherein, 1 is steel plate, and 2 is angle bar, and 3 is upper mold, and 4 is cellular board body, and 5 is lower mold, and 6 is round
Arc batten, 7 is countersunk head wood screw, and 8 is the straight angle.
Detailed description of the invention
Below according to accompanying drawing, this utility model is described further.
As shown in Fig. 1～Fig. 2, described upper mold 3 is L-shaped, and described lower mold 5 is L-shaped, is provided with honeycomb between lower mold 5 and upper mold 3
Plate body 4, the outside of described upper mold 3 right angle is provided with angle bar 2, described angle bar 2 be arranged over steel plate 1；It is positioned at cellular board originally
The inner side of lower mold 5 right angle below body 4 is provided with circular arc batten 6.
The outside of described lower mold 5 right angle is provided with the straight angle 8.
Being embedded with countersunk head wood screw 7 in described circular arc batten 6, the bottom of described countersunk head wood screw 7 is connected with lower mold 5, flat
The top of pollard screw 7 is less than the arc-shaped surface of circular arc batten 6.
When this utility model uses, circular arc batten 6 countersunk head wood screw 7 is fixed on the right angle inside lower mold 5, it is ensured that
Countersunk head wood screw 7 is less than the arc-shaped surface of circular arc batten 6, and circular arc batten 6 fits tightly with lower mold 5, and transition face is without raised step.
The composite plate that laying is good is placed on the inner side of lower mold 5 subsequently, and upper mold 3 and lower mold 5 carry out die closing operation, and the W of honeycomb hole to
Consistent with the bending direction at 90 ° of R angles.
First fasten steel plate 1 and the straight angle 8 of mould composition subsequently by C-type clamp, be forced into plate thickness reach required thickness ±
In the range of 0.2mm, then C-type clamp is utilized to fasten whole die sheet surface the most successively.
