Description
Technical field
The utility model relates to a kind of profile shapes structure field, is specifically related to the rotary profile shapes grid structure of a kind of positive/negative thread.
Background technique
Along with the progress of 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 overall 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 purpose of this utility model is to overcome the above problem that prior art exists, provide a kind of positive/negative thread rotary profile shapes grid structure, the utility model 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 utility model 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 as required the shape of net.
Further, described in the middle of the thickness of body can be zero, to be now transparent apertures netted for profile shapes entirety, can be also one deck thin-walled, once disclosing brokenly, can be also abundant body, 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 beneficial effects of the utility model are:
The utility model 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 solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is that a kind of embodiment's of the utility model axle measures intention;
Fig. 2 is a kind of embodiment's of the utility model end view;
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 utility model 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 as required the shape of net.
Further, described in the middle of the thickness of body 1 can be zero, to be now transparent apertures netted for profile shapes entirety, can be also one deck thin-walled, once disclosing brokenly, can be also abundant body, 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, rotary positive/negative thread profile shapes grid structure can be divided into external spiral rib group 1, middle body 2, with internal spiral rib group 3, intercept the cross section of the rotary profile shapes rack of 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, be rotated by the lead angle of setting to another way, the angle of lead angle is at most that can to have the angle of be zero, can obtain different netted profile shapes by different lead angles, , just obtain 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 preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
