Description
Technical field
The present invention relates to a kind of profile shapes structure field, be specifically related to the rotary profile shapes grid structure of a kind of positive/negative thread.
Background technique
Progress along with production technology, progressing greatly of production technology, the raising of Mould Machining precision, the progress of material technology, control the miniaturization of component, originally in a lot of general knowledge, think that the thing that can not accomplish also becomes practical, but also economical and practical, in the past, the sectional shape of profile shapes and size can not change, direction and angle also must be in full accord, and this kind of confinement is now under the precision manufacture of mould and the flexible tackling key problem of material technology, can be broken, up-to-date technical research achievement can produce that cross-sectional sizes constantly changes and cross section also can part or whole translation and the profile shapes of rotation, and the profile shapes of Novel structure is also having many new function and new feature, cost performance is higher, material property is better.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, provide a kind of positive/negative thread rotary profile shapes grid structure, the present invention is with low cost, easy to process, be applicable to super large batch automatic production, a kind of making method of profile shapes rigid body net is provided, can manufacture visual radome, non-visual radome, cage cylinder, decorates net post, fence, high impact-resistant protection material, filter screen stands etc., have significantly improved intensity and the bend resistance performance of profile shapes under equal conditions, combination property is superior.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
The rotary profile shapes grid structure of a kind of positive/negative thread, comprise that internal spiral rib group, middle body and external spiral rib group form, connect from inside to outside successively, the cross section of described internal spiral rib group is left-handed or dextrorotation by the lead angle of a setting, the cross section of described external spiral rib group is or dextrorotation left-handed by the lead angle of a setting also, but rotation direction is contrary with the cross section rotation direction of internal spiral rib group.
Further, the lead angle that described internal spiral rib group is set can be consistent with the cross section lead angle of external spiral rib group, but also can be inconsistent, can regulate through adjusting the angle of lead angle the shape of net as required.
Further, the thickness of described middle body can be zero, is transparent apertures netted, can be also one deck thin-walled, once disclosing brokenly, can be also abundant body, and counter-bending deformability is superpower.
Further, the thickness of the bending deflection easily of described internal spiral rib group thinner thickness, middle body is zero, the also thinner thickness bending deflection easily of external spiral rib group, now annular enclosed thin profile shapes net just can be cut off, and folds and is compacted into plane profile shapes net.
The invention has the beneficial effects as follows:
The present invention is with low cost, easy to process, be applicable to super large batch automatic production, a kind of making method of profile shapes rigid body net is provided, can manufacture visual radome, non-visual radome, cage cylinder, decorates net post, fence, high impact-resistant protection material, filter screen stands etc., have significantly improved intensity and the bend resistance performance of profile shapes under equal conditions, combination property is superior.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, forms the application's a part, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is that the axle of an embodiment of the present invention measures intention;
Fig. 2 is the end view of an embodiment of the present invention;
Number in the figure explanation: 1, external spiral rib group, 2, middle body, 3, internal spiral rib group, 4, profile shapes net inner space.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 2, the rotary profile shapes grid structure of a kind of positive/negative thread, comprise that internal spiral rib group 3, middle body 2 and external spiral rib group 1 form, connect from inside to outside successively, the cross section of described internal spiral rib group 3 is left-handed or dextrorotation by the lead angle of a setting, the cross section of described external spiral rib group 1 is or dextrorotation left-handed by the lead angle of a setting also, but rotation direction is contrary with the cross section rotation direction of internal spiral rib group.
Further, the lead angle that described internal spiral rib group 3 is set can be consistent with the cross section lead angle of external spiral rib group 1, but also can be inconsistent, can regulate through adjusting the angle of lead angle the shape of net as required.
Further, the thickness of described middle body 1 can be zero, is transparent apertures netted, can be also one deck thin-walled, once disclosing brokenly, can be also abundant body, and counter-bending deformability is superpower.
Further, the thickness of the bending deflection easily of described internal spiral rib group 3 thinner thicknesses, middle body 2 is zero, also thinner thickness bending deflection easily of external spiral rib group 1, now annular enclosed thin profile shapes net just can be cut off, and folds and is compacted into plane profile shapes net.
The working principle of the present embodiment is as follows:
By structure as shown in Figure 1 to Figure 2, the rotary profile shapes grid structure of positive/negative thread can be divided into external spiral rib group 1, middle body 2, with internal spiral rib group 3, the cross section of the rotary profile shapes rack of intercepting positive/negative thread, be summarized as two-part, a part is that external spiral rib group 1 is rotated by the lead angle of setting towards a direction, another part is internal spiral rib group 3, by the lead angle of setting, be rotated to another way, the angle of lead angle is at most that can to have the angle of be zero, by different lead angles, can obtain different netted profile shapes, , just obtained the rotatable profile shapes of external thread rotary that we want, the bending deflection easily of internal spiral rib group 3 thinner thicknesses, the thickness of middle body 2 is zero, also thinner thickness bending deflection easily of external spiral rib group 1, now annular enclosed thin profile shapes net just can be cut off, fold and be compacted into plane profile shapes net.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
