Specific embodiment

Specific embodiments of the present invention are described in detail below in conjunction with attached drawing.It should be understood that described herein Specific embodiment be merely to illustrate and explain the present invention, be not intended to restrict the invention.

Below with reference to the accompanying drawings thermoplasticity core material according to the present invention and its production method and production equipment are described.

Referring to Fig. 1 a to Fig. 1 e, by different angle and in a manner of illustrate the thermoplastic core of first embodiment according to the present invention The structure of material.

In the first embodiment, thermoplasticity core material is shown as honeycomb shaped, i.e. unit group shown in Fig. 1 a in shape Zoarium 100.In composed structure, which is spliced by being laminated along first direction D1 extension and in a second direction D2 Multiple sheet material units 30 be composed.Wherein, the sheet surface of at least part of sheet material unit 30 is formed with along first direction The non-closed geometrical shaped body 104 that D1 is sequentially distributed.Shape in shape, as shown in Fig. 1 a, Fig. 1 c, spelled by sheet material unit 30 The unit assembly 100 for connecing composition includes being spliced to form by geometrical shaped body 104 and along multiple axis of first direction D1 distribution Pore structure, axial aperture structure include the axial pass-through holes 101 axially along third direction D3 and the circumferential direction envelope around axial pass-through holes 101 The axis hole peripheral wall closed.

In thermoplasticity core material of the invention, sheet material unit 30 can be divided into flat sheets unit 31 and sheet surface be formed with it is several 32 two kinds of the geometry sheet material unit of what bodies 104.Undressed geometrical shaped body out in the sheet surface of flat sheets unit 31 104, so that sheet surface is flat, geometrical shaped body 104 is then machined in the sheet surface of geometry sheet material unit 32.Scheming In each embodiment shown, the shape and structure of multiple geometrical shaped bodies 104 on the same geometry sheet material unit 32 is all the same, i.e., Geometrical shaped body 104 is repeated in presentation along first direction D1, however, the present invention is not limited thereto, on each geometry sheet material unit 32 The shape and structure of multiple geometrical shaped bodies 104 can not also be identical.Moreover, each geometry sheet material list of component units assembly 100 Geometrical shaped body 104 in member 32 can be identical, can also be different.In first embodiment shown in the drawings into the 7th embodiment, structure Each sheet material unit 30 at unit assembly 100 is the geometric form on geometry sheet material unit and each geometry sheet material unit 32 The planform of shape body 104 is all the same.Each sheet material unit 30 in 8th embodiment is geometry sheet material unit, but including edge The two distinct types of geometry sheet material unit of the alternately laminated arrangement in the direction D2, i.e. unit assembly 100 include geometrical shaped body 104 at least two different geometry sheet material units 32.In the 9th embodiment of Fig. 9, then by along the alternately laminated arrangement in the direction D2 Flat sheets unit 31 and geometry sheet material unit 32 constitute.

Shape in shape, at least formed with the multiple axial aperture structures being distributed along first direction D1 in unit assembly 100, Multiple axial aperture structures can be distributed in a line or multirow, and each axial aperture structure includes the axial pass-through holes axially along third direction D3 101 and around axial pass-through holes 101 circumferentially closed axis hole peripheral wall.Wherein, each axial aperture structure can be by least one geometry Bodies 104 with the inner hole circumferential closure structure of the corresponding non-closed opening for closing at least one geometrical shaped body 104 and Composition.The inner hole circumferential closure structure of the non-close opening of closed geometric shape body 104 can be in adjacent sheet material unit 30 Flat sheets, the non-flat sheets including partial geometry bodies 104 being also possible in adjacent sheet material unit 30.

About non-closed geometrical shaped body 104, it is defined as being formed as the sheet surface in sheet material unit 30 along second party To the geometry lug boss of D2 protuberance, it is formed in geometry lug boss and penetrates through axially along third direction D3 and closed in sheet surface in non- Close the geometry inner hole 105 of shape.Geometrical shaped body 104 can be formed in the compression moulding structure of sheet surface, at this time in geometry Then to be pressed into type hole, geometry inner hole 105 is formed as non-occluded state in sheet surface in hole 105.

According to the difference of processing method and machine direction (one-way or bi-directional), geometrical shaped body 104 be may be formed at a piece of Material surface also may be formed on the opposite two sheets surface of sheet material, i.e., respectively from sheet material top surface and sheet material bottom surface along second Direction D2 is swelled towards opposite direction.When geometrical shaped body 104 is formed simultaneously at sheet material top surface and sheet material bottom surface, then part Geometrical shaped body 104 is from sheet material top surface towards sheet material bottom surface protrusion, and the geometrical shaped body 104 of another part is from sheet material bottom surface direction Sheet material top surface protrusion.

Below in conjunction in the explanation of attached drawing, it is not easy to obscure for ease of understanding, for unidirectionally processing, i.e. geometrical shaped body 104 are both formed in unified sheet surface or uniformly from sheet material top surface towards sheet material bottom surface protrusion or uniformly from sheet material bottom Facing towards sheet material top surface protrusion.Therefore the geometrical shaped body 104 indicated in Fig. 1 d, Fig. 1 e is towards the single side of second direction D2 To convex, i.e., all from sheet material top surface towards sheet material bottom surface protrusion, to all be formed with low spot 103 on geometrical shaped body 104. But it will be appreciated to those of skill in the art that being then located at the two neighboring several of mark in Fig. 1 d, Fig. 1 e according to two-way processing Between what bodies 104 and to be formed with the part of high point 102 be also geometrical shaped body, only with the geometry that is formed with low spot 103 The machine direction (or protrusion direction) of bodies is on the contrary, geometry spacer holes 106 are also geometry inner hole at this time.

But it either defines geometrical shaped body 104 to be unidirectional protrusion or can be two-way protrusion, as shown in fig. le, in shape On, after processing geometrical shaped body 104, the high point 102 along the distribution of first direction D1 alternate intervals is formed on sheet material unit 30 With low spot 103, high point 102 and low spot 103 can be plane or line, be connect with being constituted plane between adjacent sheet material unit 30 Touching or wire-shaped contact.

Below for ease of understanding, by sheet material unit 30 be considered as by flat sheets using unidirectional processing and formed it is each Geometrical shaped body 104, by taking Fig. 1 d, Fig. 1 e as an example, geometrical shaped body 104 is intervally arranged along first direction D1, is from sheet material list The downwardly projecting geometry lug boss in sheet material top surface of member 30, i.e. half hexahedron protrusion, so that geometry inner hole 105 is towards sheet material top The top side in face forms the openning shape of non-close.Geometry inner hole centreline OO' is along third direction D3.At this point, adjacent geometry The geometry spacer holes 106 of non-close, the non-close opening of geometry inner hole 105 and geometry spacer holes 106 can be also formed between body 104 Towards on the contrary.In nine embodiments shown in the drawings, geometrical shaped body 104 uniformly from the sheet material top surface of sheet material unit 30 to Lower protrusion molding, as shown in fig. le.Therefore, 102 place plane of high point is sheet material top surface, and low spot 103 is geometrical shaped body 104 Salient point.

Multiple sheet material units 30 are in second direction D2 stacked arrangement, if being positive with the protrusion direction of geometrical shaped body 104 To, then sheet material unit 30 can forward direction put and also reversely put, have successively dividing along first direction D1 as long as can be spliced into The unit assembly 100 of the axial aperture structure of cloth.

When being spliced into unit assembly 100, b, Fig. 8 b and Fig. 9 referring to Fig.1, the first sheet material unit of arbitrary neighborhood and In two sheet material units, at least one of the first sheet material unit and the second sheet material unit are geometry sheet material unit, by geometry piece Material unit spliced formed axial aperture structure in, each axial pass-through holes 101 include the first sheet material unit at least one first First geometry inner hole of geometrical shaped body, each axial aperture structure include at least one first geometric form on the first sheet material unit For circumferentially closing the inner hole circumferential closure of the first geometry inner hole of the first geometrical shaped body on shape body and the second sheet material unit Structure, inner hole circumferential closure structure is for flat wall or including at least part of second geometrical shaped body.

As a specific example, in first embodiment into the 7th embodiment, the geometrical shaped body 104 on sheet material unit 30 is equal Uniformly from the downwardly projecting molding in sheet material top surface of sheet material unit 30, the equal planform of all geometrical shaped bodies 104 is identical.Such as figure Shown in 1c, when D2 arranges in a second direction, the same direction of the geometrical shaped body 104 of each sheet material unit 30 D2 in a second direction (in figure downwards) arrangement, the first sheet material unit of arbitrary neighborhood and alignment thereof of the second sheet material unit are as follows: so that the first sheet material D2's second geometrical shaped body of the first geometrical shaped body on unit and the second sheet material unit is staggered in a second direction, i.e. non-alignment State.Meanwhile first geometrical shaped body be successively alternately arranged with the second geometrical shaped body along first direction D1.In this way, such as Fig. 1 b, Shown in Fig. 1 c, 106 split of geometry spacer holes that axial pass-through holes 101 are aligned by a geometry inner hole 105 with D2 in a second direction It forms.At this point, the inner hole circumferential closure structure of the geometrical shaped body 104 includes the sheet material flat wall on adjacent sheet material unit 30 And its geometrical shaped body 104 of the part of two sides.Certainly, in the shape and structure of each geometrical shaped body 104 of sheet material unit 30 Identical and when being equidistantly spaced from, mobile adjustment appropriate at this time can also form suitable unit along the aligned position of first direction D1 Assembly 100.

In figure 8b, it is clear that the axial pass-through holes 101 of part include a geometry inner hole 105, the axial pass-through holes of part 101 include two geometry inner holes 105.In Fig. 9, then each axial pass-through holes 101 include a geometry inner hole 105, and inner hole Circumferential closure structure is flat sheets unit 31.

It to sum up, only need to be at the both ends along first direction D1 when the shape and structure of each sheet material unit 30 is all identical On the basis of multiple sheet material units 30 of alignment, each sheet material unit 30 is surrounded to the rotation axis (example for being parallel to first direction D1 Such as the long side of sheet material unit 30) overturning, wherein so that the reverses direction of the two sheets unit 30 of arbitrary neighborhood on the contrary, to The geometrical shaped body 104 on another sheet material unit 30 after geometrical shaped body 104 and reverse flip on one sheet material unit 30 D2 alignment and integrally connected in a second direction.Wherein, in the sheet material unit 30 after reverse flip, the position of spikes/low- points is mutual It changes.Certainly, the two sheets unit 30 of arbitrary neighborhood can also be surrounded to rotation axis (such as the sheet material for being parallel to first direction D1 The long side of unit 30) overturning and reverses direction it is consistent, and then along first direction D1 move adjusting with the certain distance that is staggered, thus such as It is preceding describedly so that the second geometric form on the first geometrical shaped body on the first sheet material unit and the second adjacent sheet material unit Shape body is successively alternately arranged along first direction D1.As a result, based on any of the above-described arrangement overturning rule, strictly can accordingly be formed whole A unit assembly 100.

8th embodiment shown in Fig. 8 a and Fig. 8 b is different from any one of first embodiment into the 7th embodiment.? In 8th embodiment, the shape and structure of each sheet material unit 30 of Component units assembly 100 is different, that is, includes at least two kinds The geometry sheet material unit of type constitutes the combined and spliced of profile sheeting unit.For example, in a kind of sheet material unit 30 shown in Fig. 8 b Geometry inner hole 105 be half hexagonal hole shape, the geometry inner hole 105 in another sheet material unit 30 is half diamond hole Shape, and the geometrical shaped body 104 in two kinds of sheet material units 30 can be different along the span of first direction D1.

Due to including at least two kinds of geometry sheet material unit, so that there is not similar shape in entire unit assembly 100 A variety of axial pass-through holes 101 of shape.Such as in Fig. 8 b the shown the top the first row along the interval first direction D1 it is multiple In axial pass-through holes 101, each axial pass-through holes 101 by three and half diamond shape hole shapes geometry spacer holes 106 and two and half 105 split of geometry inner hole of regular hexagon hole shape is constituted.In multiple axial pass-through holes 101 of the second row of top, including along Two kinds of axial pass-through holes 101 of one direction D1 alternate intervals, one of axial pass-through holes 101 are by one and half hexagonal hole shapes 105 split of geometry inner hole of the geometry spacer holes 106 of shape and two and half diamond shape hole shapes is constituted, another axial pass-through holes 101 It is made of the geometry spacer holes 106 of one and half regular hexagon hole shapes and 105 split of geometry inner hole of one and half diamond shape hole shapes. From Fig. 8 b as it can be seen that different shape structure geometry sheet material unit constitute profile sheeting unit it is combined and spliced when, it is not each High point 102 and low spot 103, which can correspond to, to connect, and the high point 102 or low spot 103 of part can be in hanging shape.

It should be noted that constitute above profile sheeting unit it is combined and spliced when, can also be other such as half water chestnuts Shape hole and half kidney slot are spliced into axial pass-through holes 101.In addition, the contact surface of the contact portion between sheet material unit 30 is not limited to together Type face connects, and is also possible to such as plane and docking for cambered surface etc..In unit assembly 100, axial pass-through holes 101 Shape is not limited to each shape shown in the drawings, is also possible to regular quadrangle, circle etc., not reinflated herein carefully to state.

In addition, sheet material unit 30 can be single sheet structure, it is also possible to multi-layer sheet structure.As shown in Figure 10, several What sheet material unit 32 includes tri- layers of A, B, C, and layers of material may be the same or different.It, can when wherein the material of adjacent two layers is identical It is considered as same layer.When adjacent geometry sheet material unit 32 is combined into cell cube assembly 100, combination can be A-A- The A layer of C-C contact, i.e. the A layer of the geometry sheet material unit 32 geometry sheet material unit 32 adjacent with side combines, while geometry sheet material The C layer of the C layer of the unit 32 geometry sheet material unit 32 adjacent with the other side combines.Can certainly be such as A-C-A-C or The combination of A-A-C-C-A-C also can also be combination more than both aforesaid ways or both.When existing in combination When A-C is combined, a certain distance can be mutually staggered between geometry sheet material unit 32 neighbouring at this time and is then combined.

The thermoplasticity core material of the simple and novel honeycomb shape of composed structure is elaborated in conjunction with attached drawing above, passes through single piece Material unit 30 is arranged with simple rule, polymerization can form core material, and manufacture easy to process reduces cost, will also carefully state below.But The advantages of thermoplasticity core material of the invention, is without being limited thereto, it is often more important that, due to processing convenience set forth below, according to this The wall thickness of the thermoplasticity core material of invention can have biggish wall thickness, other reinforcing materials etc. can be filled, to realize high intensity, especially It is suitable for heavily loaded field etc..

The thermoplasticity core material of existing round tube honeycomb or semiclosed folded-sheet honeycomb structure is required in forming process using plastic uptake Or blow molding process, which limits the maximum hole walls of honeycomb hole, and process flow is discontinuous, and processing efficiency is low, at high cost.? For thickest by limited time, central filler material is easy to produce broken wall, to destroy the structure of core material, forms rejected product.At this In the embodiment of invention, sheet material unit 30 squeezes out profile 10 ' by smooth 10 compression moulding of sheet material or directly, no blow molding or Plastic uptake link, so that the technique in terms of without wall thickness limits.Referring to Fig. 1 b, in axial pass-through holes 101, axial pass-through holes 101 Axis hole peripheral wall is divided into contact portion wall thickness and non-contact portion wall thickness, in thermoplasticity core material of the invention, the axis of axial pass-through holes 101 The minimum thickness of hole peripheral wall should be not less than 0.1mm, and the maximum gauge of axis hole peripheral wall is not only restricted to processing technology, can set as required Meter prevents broken wall on the basis of guaranteeing light heavy duty.In addition, can be by the external of the axial pass-through holes 101 of arbitrary shape Diameter of a circle is preferably arranged to not less than 1mm；And/or it can be by the hole axial length of the axial pass-through holes 101 of arbitrary shape and the axial direction The diameter ratio of the circumscribed circle of through hole 101 is preferably arranged to no more than 200, so that core material obtains more preferably heavily loaded lightweight effect Fruit.

In the present invention, the material of sheet material unit 30 uses thermoplastic material, and the metal formings material such as non-aluminum, iron, with Realize itself lightweight, thus the material of sheet material unit 30 may include thermoplastic polymer, filler filling thermoplastic polymer, Fibre-reinforced thermoplastic resin based composite material and/or plastic deformation paper, steel plastic compount object etc..As an example, thermoplastic Property polymer can be polypropylene, polyethylene, polyamide, thermoplastic polyester, polyvinyl chloride, polystyrene, polycarbonate, polyphenyl Ether, thermoplastic elastomer (TPE), multi-component copolymer thermoplastic, polymethyl methacrylate, polyphenylene sulfide, polyether-ether-ketone and polyamides are sub- One of amine or in which a variety of blends.In the thermoplastic polymer of filler filling, filler can be organic matter, nothing Machine object or both have, specifically, filler can be wax, talcum powder, carbon black, white carbon black, kaolin, calcium carbonate, tristearin One of acid, calcium stearate, whisker, titanium dioxide, iron oxide, pigment, fire retardant and antioxidant or in which a variety of combinations Object.Fiber in the fibre-reinforced thermoplastic resin based composite material can be fine for organic fiber, inorfil, metal One of dimension, macromolecular fibre, plant fiber are a variety of.Fibre in the fibre-reinforced thermoplastic resin based composite material Dimension can be poly- for glass fibre, carbon fiber, basalt fibre, steel wire fibre, polypropylene fibre, polyester fiber, super high molecular weight One of vinyl fiber, polyimide fiber and flaxen fiber or many of composition.

As shown in Figure 10, sheet material unit 30 or go out the sheet material 10 of sheet material unit 30 for machine-shaping or profile 10 ' can be with It is single layer structure or multilayered structure, such as the sandwich sandwich of diagram, wherein may include central filler material layer, such as schemes The B layer shown.Central filler material layer can be enhanced packing material and/or function packing material.Enhanced packing material can Significantly increase core material intensity, function packing material, such as fire proofing and/or acoustic material can also be filled, with realize it is fire-retardant, The functions such as sound insulation.The thermoplasticity core material of this achievable relatively thick with packing material, can be advantageously applied to lightweight In high-strength more demanding every field, such as in the increasing various carrier vehicles of load-carrying, especially heavily loaded electric power transporting coal Train or cruising ability are insufficient and need to mitigate the electronic logistic car of car body etc..

To obtain the satisfactory thermoplasticity core material that can be realized lightweight heavy duty, the unit after molding shown in Fig. 1 a It, can be more as subtracting the axial pass-through holes 101 in matter hole to realize lightweight by being arranged in assembly 100.A referring to Fig.1, Unit assembly 100 is defined by first direction D1 with second direction D2 and is intersected with 100 entity of unit assembly any flat Face, i.e., in any cross sectional planes of unit assembly 100, plane voidage should be not less than 40%, further, plane gap Rate should be not less than 60%.In the above-mentioned cross sectional planes of unit assembly 100, the plane voidage, that is, each axially through The hole area of section summation in hole 101 and the ratio between the site area of the cross sectional planes.

It is light-weighted simultaneously, for realize heavy duty, in addition to material select, should also improve material volume utilization rate, i.e., along carry Lotus Impact direction is able to bear the live part of load and the mass ratio of integral part or volume ratio.For popular, along load by The true part of the force in power direction is load bearing live part, and perpendicular to the material part or blank part of load Impact direction Dividing then is load bearing inactive portion, and the material volume utilization rate of inactive portion is 0.As an example, in fig 1 a, working as third Direction D3 is when bearing compressive load direction, and the material volume utilization rate of unit assembly 100 is not less than 60%, it is preferred that material Expect that volume utilization is not less than 80%.

Wherein, the definition about material volume utilization rate has reality along loading direction when material bears compressive load Body material and the accumulative height of solid material are more than or equal to the material volume and material of the maximum height part of 95% direction material The ratio between total volume is material volume utilization rate.Since material is generally difficult to as regular shape, there are both ends defects, central defect Or other combined defects etc., in order to make it easy to understand, in combination with patented invention content, the case where will likely encountering herein point For five classes, first kind Quan Guantong, the second class is an existing defects, and third class is both ends existing defects, and the 4th class is centre Existing defects, the 5th class are combined.

Specifically, Figure 11 a~Figure 11 e ' respectively illustrates the calculation specifications of above-mentioned five classes situation, wherein compressive load side To being for Y-direction, Y₀For material maximum height, Y₁To have the height of solid material, Y₂For flaw height, material volume benefit It is S with rate₁/S₀, S₀For universe area, S₁For effective area, S₀Calculation formula is S₀=∑ dxdy.For having for five class situations Imitate area S₁Calculation specifications, will address one by one below.It should be noted that definition material volume utilization for simplicity, material Expect that the definition of volume utilization censures material volume, cross section in the Z-direction not marked in the example shown such as using cross-sectional area It is all the same with existing diagram, S can be used at this time₀Instead of material total volume, S₁Instead of material effective volume；It is such as transversal along Z-direction Face and existing diagram be not identical, then total volume is actual volume, and effective volume is then that any one cross section meets above-mentioned definition The sum of the volume of entity of effective cross section.Also, in view of material is not when destroying, can occur under load effect certain Deformation so that accumulative height is slightly below maximum height and can also bear load originally, but the deflection of material is limited, therefore is advised The maximum height of fixed accumulative direction material of the height more than or equal to 95%, i.e. Y₁≥0.95Y₀, Y₂≤0.05Y₀。

When the structure of thermoplasticity core material is full perforation, referring to Figure 11 a, Figure 11 a ', the dash area of Figure 11 a, which illustrates, to be held The total cross-section of wall is carried, the total cross-section area of the bearing wall is S₀；Having for the bearing wall of support force can be contributed in loading direction The dash area that effect part is Figure 11 a ', area S₁, S₁=S₀=∑ dxdy.It is deposited when the structure of thermoplasticity core material is one In defect, referring to Figure 11 b, Figure 11 b ', the dash area of Figure 11 b illustrates the total cross-section of bearing wall, the bearing wall it is total Cross-sectional area is S₀；The dash area that the live part of the bearing wall of support force is Figure 11 b ' can be contributed in loading direction, Area is S₁, S₁=∑ dxdy ∣ Y₀≥y≥Y₁.When the structure of thermoplasticity core material is both ends existing defects, referring to Figure 11 c, figure The dash area of 11c ', Figure 11 c illustrate the total cross-section of bearing wall, and the total cross-section area of the bearing wall is S₀；In load Direction can contribute the dash area that the live part of the bearing wall of support force is Figure 11 c ', area S₁, S₁=∑ dxdy ∣ Y₀ ≥y≥Y₁.When the structure of thermoplasticity core material is central defect, referring to Figure 11 d, Figure 11 d ', the dash area of Figure 11 d is illustrated The total cross-section of bearing wall, the total cross-section area of the bearing wall are S₀；The bearing wall of support force can be contributed in loading direction Live part is the dash area of Figure 11 d ', area S₁, S₁=∑ dxdy ∣ Y₀≥y≥Y₀-Y₂.When the knot of thermoplasticity core material When structure is combined defect, referring to Figure 11 e, Figure 11 e ', the dash area of Figure 11 e illustrates the total cross-section of bearing wall, this holds The total cross-section area for carrying wall is S₀；The shade that the live part of the bearing wall of support force is Figure 11 e ' can be contributed in loading direction Part, area S₁, S₁=∑ dxdy ∣ Y₀≥y≥Y₁And Y₀≥y≥Y₀-Y₂。

To process above-mentioned cellular thermoplasticity core material, in embodiment shown in Figure 12, Figure 13, thermoplastic core is provided The first production method of material.The axial pass-through holes shown in Fig. 1 a to Fig. 1 e with positive six faces honeycomb hole shape are combined below For 101 unit assembly 100, to illustrate the machine-shaping process of the unit assembly 100.

Referring to Figure 12, Figure 13, the production method of the thermoplasticity core material includes the following steps that assembly line is worked continuously:

S121, smooth sheet material 10 is persistently exported along assembly line outbound course X；

It is S122,10 division processing of sheet material is wide at the broadside outbound course Y along the sheet material 10 and along the flowing water Line outbound course X is in band-like multiple sheet material units 30, is wherein at least machined in the sheet surface of the sheet material unit 30 of part The non-closed geometrical shaped body 104 presented is repeated along assembly line outbound course X；

S123, each sheet material unit 30 after division processing is overturn into predetermined angle respectively, so that the sheet material list after overturning The length direction L of member 30 is kept along assembly line outbound course X, and the width direction W of sheet material unit 30 and the broadside of sheet material 10 export Angle a is formed between the Y of direction；

S124, along broadside outbound course Y by after overturning each sheet material unit 30 collapse and be laminated be spliced into unit combination Body 100.

As it can be seen that aforementioned production method has ensured the continuous production of thermoplasticity core material, can automatic assembly line production, pass through The sheet material 10 that assembly line upstream end continuously exports processes the unit assembly 100 persistently exported from assembly line downstream, compares In needing the artificial discontinuous production method participated in or interrupt, production efficiency is greatly improved, to have the big rule of versatility Mould production, the basis that product cost is greatly reduced are big.Wherein, by modes such as roll-ins, direct die mould goes out honeycomb knot on sheet material 10 The wave crest and trough of structure, i.e. geometrical shaped body 104 etc., the links such as no plastic uptake or blow molding, so that sheet material can have biggish wall thickness, More reinforcing material can be filled, so that the unit assembly 100 after roll-forming can also have biggish wall thickness, intensity is high, and And wasted without any material, realize economizing type production.

Comparably, there are mainly of two types for the existing thermoplastic resin-based honeycomb core largely used, and one is round tube bees Nest core, main technique are high speed double-layer coextrusion out compared with the single round tube of thick wall, and forming wall thickness through blow molding is 0.1~0.3mm thick More light wall pipes are superimposed as sticking together and are put into baking oven by light wall pipe, so that outer layer low temperature material melts and inner layer high temperature material holding solid-state, it is cold But it is cut as required after.Second is semiclosed folded-sheet honeycomb structure, and technical process is that continuous material passes through perpendicular to material face Plastic deformation generate, to form semi-hexagon shape cell-wall and lesser join domain, by being folded along transmission direction, unit It keeps away and meets, to form honeycomb body structure.The cellular simple process of the round tube of the first, but since production discontinuously causes, i.e., There is heating temperature-fall period in baking oven, cause round tube honeycomb production efficiency lower, high production cost, there is blow molding ring in forming process Section, leads to that functional stuffing and reinforcing filler can not be filled in material, and application is limited.Second of semiclosed folded-sheet honeycomb structure Technique production is continuous, but its it is semiclosed cause material waste more, there are plastic uptake link in molding, cause also fill out in material Functional stuffing and reinforcing filler are filled, application is limited.

And the present invention can be fully solved high cost present in above two scheme, material waste and can not fill function and fill out Material and the problem of reinforcing filler provides a kind of novel fillable, inexpensive, economizing type honeycomb core material and its production method and life Produce equipment.

In production method of the invention, flat sheets 10 can persistently be exported by the outlet of thermoplastic material molding equipment 1, Output can be persistently moved along assembly line outbound course X on horizontal pipelining platform.Sheet material 10, sheet material for ease of understanding The orientation of the different phase of unit 30 in process and mutual position relation, in each production method shown in the drawings In the embodiment of production equipment, absolute coordinate system and relative coordinate system are defined.Wherein, sheet material 10 steadily exports, can't Overturning, therefore assembly line outbound course X, broadside outbound course Y, that is, sheet material 10 length direction and width direction.Therefore, it can examine Consider and absolute coordinate system is defined with the start position of the molding outlet of sheet molding equipment or pipelining platform.Shown in attached drawing Each method and apparatus embodiment in, absolute coordinate system includes assembly line outbound course X, broadside outbound course Y and assembly line Molding outlet or the start position of pipelining platform of sheet molding equipment is arranged in platform vertical direction Z, origin position, Assembly line outbound course X, broadside outbound course Y limit the levelling bench surface of pipelining platform or jointly from the moldings Export the sheet surface of the sheet material 10 of horizontal output.Meanwhile dynamic coordinate system, i.e. sheet material unit 30 are defined for sheet material unit 30 Width direction W (i.e. third direction D3 in Fig. 1 e) and length direction L (i.e. the first direction D1 of Fig. 1 e), can clearly Show the positional relationship before and after the steering of sheet material unit 30 in process.
