Abstract

The utility model relates to a composite material with a honeycomb structure, in particular to a sandwich core with a plurality of corrugated holes. The utility model discloses a be equipped with a plurality of suitable sizes on the bonding wire that forms between the rubber coating position of each stamen piece of sandwich core and not rubber coating position and be the zigzag hole that the geometric shape was arranged to be convenient for sandwich core extension folding and pressing design, two shell surfaces of discharging when also being convenient for sandwich core and two shell surfaces bonding are impressed the unnecessary air of sandwich core (honeycomb space promptly), avoid causing the bonding part of two shell surfaces and sandwich core to come unstuck in order to do benefit to the bonding of two shell surfaces and sandwich core.

Description

Filling core with multi broken track holes

The utility model relates to a kind of honey comb structure composite, is meant a kind of sandwich stamen with a plurality of scrimps hole especially.

Sandwich stamen is the main member of sandwich complex, common sandwich stamen is except being the fixed form of material with sheet metal, Poly Foam or corrugated paper, the sandwich stamen of the honeycomb of different shape all has the architectural characteristic of transversal stretching, but as reduced volume, is convenient to store and transportation.This sandwich stamen of honeycomb with transversal stretching function as shown in Figure 1, a plurality of stamen sheets 11 of sandwich stamen 10 usefulness are its corresponding fixed point and equidistantly be bonded mutually with glue.When sandwich stamen is laterally upheld, the part that scribbles glue between stamen sheet and stamen sheet is bonding mutually, and do not scribble the part of glue, stretch bending and form the honeycomb space from stamen sheet and stamen chip bonding line 12, because the elastic force that stamen sheet material itself is had, tension force, after stamen sheet and stamen sheet cementing line are upheld, scrimp (being closing line 12 parts) through cross side press-bending folding is difficult for typing, and cause phenomenon through the inside contraction distortion of sandwich stamen of artificial extension, therefore, when being bonded in two shell faces 20 with the sandwich stamen that manually will uphold, 30, often cause the uneven situation that contracts in the sandwich stamen of extension, influence sandwich complex that structure forms and resist shearing and tensile stress between it, and sandwich stamen 10 and two shell faces 20,30 when bonding, two shell faces 20,30 can be pressed into unnecessary air to sandwich stamen, make two shell faces 20,30 with the honeycomb space 13 of sandwich stamen 10 in form compressed air, make two shell faces 20,30 cause easily with the stick portion of sandwich stamen 10 and to come unstuck, and have influenced the sandwich complex that forms and have resisted shearing and tensile stress between it.

The purpose of this utility model is to provide a kind of sandwich stamen with a plurality of scrimps hole that is easy to uphold back crimping typing, it can make two shell faces when bonding, the two shell faces of can discharging immediately are pressed into the unnecessary air of the sandwich stamen stamen heart, avoid forming compressed air in the honeycomb space of the sandwich stamen stamen heart, and the phenomenon that causes the stick portion of two shell faces and sandwich stamen to come unstuck easily.

The purpose of this utility model is achieved in that in the gluing part of each stamen sheet of sandwich stamen and does not establish the scrimp hole that a plurality of suitable sizes are geometry on the closing line of formation between the gluing part, form a kind of sandwich stamen with a plurality of scrimps hole, be convenient to sandwich stamen and uphold the crimping typing, also be convenient between sandwich stamen and two shell faces when bonding, the two shell faces of discharging are pressed into the unnecessary air of the sandwich stamen stamen heart, help the bonding of two shell faces and sandwich stamen, avoided the stick portion of two shell faces and sandwich stamen to come unstuck, both be convenient to manufacture, can have ensured again that it was firm in structure reliable.

Fig. 1 is sandwich stamen of common honeycomb and the bonding stereogram of two shell face portion.

Fig. 2 is the utility model embodiment, the two sides figure of the stamen sheet of sandwich stamen, and Fig. 2-2 is the another side of stamen sheet.

Fig. 3 is the utility model embodiment, sandwich stamen of honeycomb and the bonding stereogram of two shell face portion.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Sandwich stamen 40 is to be made of a plurality of stamen sheets 41, two corresponding surface A of relative stamen sheet 41 and B are equipped with corresponding a plurality of gluings position 411 and gluing position 412 not, the gluing position 411 of stamen sheet 41 and 412 at gluing position not, promptly form closing line 413, as shown in Figure 2, be provided with the scrimp hole 414 that a plurality of suitable sizes are geometry on closing line 413, a plurality of scrimps hole 414 is intermittently to be arranged on each bar closing line 413 of each stamen sheet 41 with equidistant from distance; The sandwich stamen 40 horizontal side pressures of C-D direction to upholding as shown in Figure 3, owing to be arranged in a plurality of scrimps hole 414 on each closing line 413 on each stamen sheet 41, a large amount of bullet (stretching) tension force that reduce each closing line 413 position material of each stamen sheet 41, make each closing line 413 slightly through crimping, its scrimp is promptly finalized the design, make sandwich stamen 40 through uphold and impose the horizontal side pressure of C-D direction after form the honeycomb space 415 of a plurality of typings, because above-mentioned sandwich stamen 40 with a plurality of scrimps hole 414, side pressure a little after the extension, can be finalized the design by crimping, and sandwich stamen 40 of this kind and two shell faces 50,60 when bonding, can discharge immediately by two shell faces 50 via a plurality of scrimps hole 414 of sandwich stamen 40 again, 60 are pressed into the unnecessary air in a plurality of honeycombs space 415 of sandwich stamen 40, make in a plurality of honeycombs space 415 of sandwich stamen 10 and can not form compressed air, and make sandwich stamen 40 and two shell faces 50, the structure of 60 bonding formation sandwich complex is fixing does not move, the phenomenon of avoiding causing the stick portion of two shell faces and sandwich stamen to come unstuck easily.

Claims (2)

1. A sandwich core with a plurality of pleated holes is composed of a plurality of cores, and a plurality of corresponding glued parts and unglued parts are arranged on the corresponding surfaces of the opposite cores. A joint line is formed between the glued part and the non-glued part, which is characterized in that a plurality of fold holes of proper size and geometric shape are arranged on the joint line. 2. The sandwich core with a plurality of pleated holes according to claim 1, characterized in that: the pleated holes are intermittently arranged at equal intervals on each joint line of each core piece.
