Abstract

A sheet of material which is made two dimensional which inlcudes portions that are removed that allows the sheet to be folded to create a three dimensional structure without the need for cutting and darting.

Description

Article and preparation method thereof

Technical field

The present invention relates to a kind of substrate that can form three-dimensional article.

Background technology

It is in light weight and possess favorable mechanical performance such as intensity that fiber is strengthened composite construction.Yet, in a lot of the application, consider cost factor, molded plastics, wood or iron construction are often by preferably, because it is made than being easier to.Yet, article, for example packing or vanning, owing to carrying damages accidentally easily, perhaps owing to weight and intensity, its ability of banking up is restricted.Fiber composite is good selection, will be a considerable factor yet be made into quite complicated three-dimensional (3D) cost that structure took place.

This is because composite construction is a starting point with flat fabric substrate usually.This substrate forms the form of article afterwards, is coated with the last layer resin afterwards, and thermoforming or be cured as desirable shape.For opposed flattened and smooth surface, this dealing with than being easier to.Yet, have the surface at angle need cut or punching press as junction, corner and the chest on limit or the bottom of packing etc.This processing labour intensity is bigger and increased production cost.It has been generally acknowledged that inexpensive article such as packing case, its fringe cost can surpass because it reinforces the income of being brought.

When fabric 3D structure can weave by special machine, relevant expense is more considerable, and making a simple structure with sewing machine seldom is feasible scheme.

Except making the 3D structure, can also produce the 3D structure by 2D flaky materials such as sheet metal, plastics, cloth, paper, cardboards of reinforcing fibre.

Correspondingly, when the three-dimensional article through reinforcement or other processing can have a lot of application, just need to reduce the cost in the production method.Could obtain large batch of relatively production and application widely like this.

Summary of the invention

Therefore main purpose of the present invention is minimizing or removes the cutting of the material sheet of making the 3D structure and necessity of punching press.

Further aim of the present invention is to simplify the making of this structure and reduces required work.

It is obvious that these and other targets and advantage will become from the present invention.

To achieve these goals, the invention provides a kind of plane lamina that is used to form the structure with 3D shape, described thin slice comprises: the material that forms first in the thin slice; The second portion of described thin slice, the material that constitutes described thin slice in the second portion of described thin slice is removed, and described second portion has orthogonal first edge and second edge; Can be folded to set up first fold line along the first direction that is parallel to described first edge with wherein said thin slice, be folded to set up second fold line along the second direction that is parallel to described second edge then, make described first edge and second edge form the relation that is in alignment with each other thus, thereby it is parallel to each other.

According to a further aspect in the invention, it provides a kind of method of utilizing thin slice to form the structure with 3D shape, comprises step: form described thin slice has the thin slice of sheeting with generation first; A part of removing described thin slice is to produce the second portion of the described thin slice that does not have sheeting, and described second portion has orthogonal first edge and second edge; Along the folding described thin slice of first fold line that is parallel to described first edge, fold described thin slice to form second fold line along the second direction that is parallel to described second edge then, make described first edge and described second edge form the relation that is in alignment with each other thus, thereby it is parallel to each other.

The present invention aims to provide a kind of special material sheet of 3D structure that is.It is a starting point with the 2D structure, forms the 3D structure afterwards, particularly has the 3D structure of deep-draw shaped structure.For reaching this purpose, material sheet forms by this way, and it has the zone at the edge that can gather and twist the 3D structure that forms by folded sheet.Keep intact or can be by being engaged as welding, thermal or bonding mode in the edge of the thin slice remaining part of formation removal zone boundary.

Description of drawings

Embodiment is elaborated to following by the reference accompanying drawing, can realizes target of the present invention and advantage.Wherein:

Fig. 1 shows the plane 2D flaky material that contains based on the present invention's instruction;

Fig. 2 A-2D shows the process that sheet fold is obtained the deep-draw shaped structure;

Fig. 3 shows and has removed a plurality of areas and by 2D the thin slice folding or labyrinth made of stretching; And

Fig. 4 is the perspective view by the 3D structure of thin slice made shown in Figure 3.

The specific embodiment

At length with reference to accompanying drawing, wherein identical drawing reference numeral is represented components identical below.The material sheet 10 that is used to illustrate plane 2D of the present invention has been shown among Fig. 1.Thin slice 10 can be the material that sheet metal, plastics, cloth, paper, cardboard etc. can achieve the goal.

Referring to Fig. 1, thin slice 10 has been divided into zone or area 12-28 along fold line 30-36.Perhaps sheeting is removed, and perhaps forms the thin slice that does not stay opening herein.

In case the structure of thin slice 10 forms, it just can form the shape that needs.

Referring to Fig. 2 A-2D, Fig. 2 A is a plane 2D thin slice 10.Thin slice 10 folds along fold line 30 and 32 afterwards.Then shown in Fig. 2 C thin slice 10 along with fold line 30 fold line 34 vertical and 36 folding with 32.As Fig. 2 D,, allow adjacent area to be folded into syntople in this process because regional 20 places do not have material.Edge or corner 38 can keep naturally, perhaps can engage by welding, thermal, splicing or other modes that can achieve the goal.Can auto-folder, also can be folding by other suitable methods that achieve the goal.

Above-mentioned advantage has been avoided cutting or punching press, has reduced the required amount of labour and the ultimate cost of article like this.The present invention has quickened the automation of making, and then has expanded the application of this structure.

Fig. 3 shows plane 2D thin slice 110.Thin slice 110 illustrates the zone 120 that a plurality of materials are emptied.Such thin slice 120 can fold and form labyrinth 130 as shown in Figure 4.Certainly the conversion of size by removing material area and position also can obtain other shape.

Like this, objects and advantages of the present invention are achieved, although preferred embodiment is disclosed and illustrate that its protection domain is not limited only to this herein, protection scope of the present invention is only determined by claim.
