Abstract
The utility model relates to a high fracture-place no-stress acupuncture needle, which is mainly composed of an improved needle body and an easily breaking zone added on a needle waist. A stress concentration point which is generated because of the processing of a stab hook is eliminated through the changing of the needle body; the elastic curve of the needle body is improved; the volume of the tip part of the easily ground stab hook is enlarged; the insufficiency that the hardness of the root of the needle body is not enough because of the oversize changing diameter ratio and the breaking position of the needle body is low can be overcome. The surface quality of the braid and a stripping net board can be protected by the stab needle; the impact force of the needle body is big, and the acupuncture needle is not easy to break off. The utility model has the advantages of abrasion resistance and long service life.
Description
The utility model is about the nonwoven production acupuncture needle.
The acupuncture needle that uses is directly to process the thorn hook on the triangle rib at present, original just very little needle body cross section is more dwindled, the stress concentration point identical with thorn hook quantity that forms easily makes pricker fracture, because needle body portion and pin waist reducing are than excessive, when it is heat-treated, the less needle body portion hardness of pin waist that diameter is bigger and diameter is unbalanced, when the needle body is subjected to big external force and fractures, needle body root bending, because disconnected position is low, needle body root easily hooks fiber at fabric face and causes the defect mark, and can aggravate the bending of pricker remainder at short notice, stabs and damages the stripping web plate.
The purpose of this utility model is to provide that a kind of to hold impulse force big, frangibility not, long service life and the novel pricker that has high fracture-place and stripping web plate and fabric are shielded.
This pricker adopts three cambered surfaces to form needle body profile, and respectively has the band shape of a semicircular in shape to extrude the limit in 120 ° of intersections of three cambered surfaces, and extruding the limit height is 1/10～1/6 of diameter of needle body.The three cambered surface needle bodys that the band semicircle shape is extruded the limit are to utilize the extruding synchronously of shaping mould three-dimensional to form.Thorn bill portion be a semicircle, extrudes on the limit in band shape and cuts a hole, mills, grinds and form.The pin waist has one to four radial ringed technology groove, when the ratio of pin waist diameter and diameter of needle body below 1.3,1.3～1.5,1.5～1.8,1.8 when above, open 1,2,3,4 annular technology groove at the pin waist respectively.When opening an annular technology groove, its groove interior diameter should be big by about 20% than diameter of needle body, and groove width is 1.5～2.5 times of pin waist diameter; When opening two annular technology grooves, article one, groove is opened at nearly needle body end, the second groove is opened at nearly handle rod end, article one, the groove interior diameter is bigger by about 20% than diameter of needle body, groove width is 1～2 times of pin waist diameter, second groove interior diameter is bigger by about 20% than article one groove interior diameter, and groove width is 2 times of article one groove width; When opening three annular technology grooves, first and second groove is opened at nearly needle body end, article three, groove is opened at nearly handle rod end, article one, the groove interior diameter is bigger by about 20% than diameter of needle body, second groove interior diameter is bigger by about 20% than article one groove interior diameter, and the 3rd groove interior diameter equates that with second groove interior diameter first and second groove width is 1～2 times of pin waist diameter, separation equates with groove width, and the 3rd groove width is 2 times of first and second groove width; When opening four annular technology grooves, first, second and third groove is opened at nearly needle body end, article four, groove is opened at nearly handle rod end, article one, the groove interior diameter is bigger by about 20% than diameter of needle body, second groove interior diameter is bigger by about 20% than article one groove interior diameter, article three, the groove interior diameter is bigger by about 20% than second groove interior diameter, article four, the groove interior diameter equates with the 3rd groove interior diameter, first, second and third groove width is 1～2 times of pin waist diameter, separation equates with groove width, and the 4th groove width is 2 times of first, second and third groove width.Methods such as the annular technology groove can utilize car, mills, footpath forging, mill process.Looking the processing method bottom land is circular-arc or flat.
This pricker is owing to extrude processing thorn hook on the limit in semicircle, eliminated the stress concentration point on the needle body, improved needle body endurance degree, can also be under the situation that does not strengthen thorn hook height, the minimum deeply degree of needle body radius, suitably strengthen thorn hook tip and needle body sectional area the most easy to wear, strengthened thorn hook ABRASION RESISTANCE and increased the needle body and held impulse force.The annular technology groove of pin waist has been eliminated reducing than big and the needle body and pin waist joint hardness that form are not enough; leaving the easily broken protection zone of formation excess load, fiber web certain altitude place; make whole needle body good rigidly; elastic curve is mild; acupuncture power is big; frangibility is not wear-resistant, protection fabric face quality and acupuncture apparatus.
