自行车轮圈及其制造方法 Method for producing a bicycle rim and

技术领域 FIELD

背景技术 Background technique

[0002] 现有的自行车轮圈的制作方法,有利用碳纤维复合材制作成形的方法,可参考中国台湾第1308520及1329080号专利所述,主要是在碳纤维复合材中置入气袋,并在对碳纤维复合材加热加压成型的同时,将气袋充气,以制成中空的碳纤维轮圈。 [0002] The manufacturing method of a conventional bicycle rim, a carbon fiber composite material are made using molded, reference No. 1329080 Patent 1,308,520 of China Taiwan and the main bag is placed in a carbon fiber composite material, and while the carbon fiber composite material to heat and pressure molding, the bag is inflated to form a hollow carbon fiber rims. 其中,气袋受到气体压力作用时均匀地向外膨胀,而碳纤维轮圈的截面形状则非均匀的圆形,致使在热压成型的同时,碳纤维轮圈的侧面将受到气袋较大力量压迫,使碳纤维轮圈的侧面较薄,其他部分较厚,容易使轮圈侧面的厚度太低,而使轮圈的结构强度下降。 Wherein the air bag expands outward uniformly by the gas pressure, the cross-sectional shape of the carbon fiber rim of the non-uniform circular, so that while pressing molding, the carbon fiber rim side air bag will be subject to greater compression strength the carbon fiber thinner side surface of the rim, other thicker portion, the thickness of the rim side surface easily too low, decrease the structural strength of the rim.

[0003] 再者,传统的在充气气袋表面叠贴纤维布的手段,往往碍于气袋外观与轮圈差异过大,以及气袋充气时弹性变形量大(过软),故叠贴纤维布过程较缓慢,且叠贴位置的精确性也较差,进而产生轮圈成型后的整体厚度不均的问题。 [0003] Moreover, the traditional means of an inflatable bag attached to the surface of the stack of fiber cloth, often because of the appearance of the bag and the rim difference is too large, and the elastic deformation amount when the air bag inflator (too soft), so that the stack stickers process slower fiber cloth, and the position accuracy is poor stick stack, thereby generating unevenness in the entire thickness of the rim molding problems.

[0004] 此外,如中国台湾专利第1308527号所述的自行车轮圈的制造方法,是将气袋分段地充气与加热,以取得较佳的耐高温特性与抗磨特性,然而,该专利所述的制造方法需进行多段的加热加压及充气程序,使得生产过程有较复杂以及速度较慢的问题。 [0004] Further, as a method for producing a bicycle rim China Taiwan Patent No. 1308527 according to, the air bag is inflated with the heating sections to achieve a better high temperature properties and wear characteristics, however, this patent the method for producing the multi-stage heating need to be inflated and pressing procedures, so that the production process is complicated and there is the problem of slow.

[0050] 在修整步骤中,另取碳纤维复合材的片体5盖合于该二开孔43并黏合于该碳纤维轮圈4,该片体5为对应碳纤维轮圈4环形顶面41的弧形片体。 [0050] In the trimming step, the other 5 take a carbon fiber composite sheet material is covered on the two openings 43 and bonding to the carbon fiber rim 4, the sheet 5 is the annular top surface 41 Arc 4 corresponding to carbon fiber rims shaped sheet. 较佳地,该弧形的片体5黏合于该两个凹槽的底面421,又较佳地,可令该片体5的厚度与凹槽42的深度相同,使黏合后的片体5与环形顶面41平齐。 Preferably, the sheet 5 is arcuate bottom surface 421 of the adhesive to the two grooves, and preferably, can make the sheet thickness and the same groove 42 of depth 5, the sheet 5 after bonding 41 flush with the annular top surface. 其中所述的黏合,是指令片体5与碳纤维轮圈4相互固定, 其固定方式可利用胶体进行黏合,也可利用热熔方式,令片体5与碳纤维轮圈4表面局部熔化而结合固定。 Wherein said adhesive is an instruction sheet 5 and the rim 4 of carbon fibers fixed to each other, which can be used in a fixed manner colloid adhesive, hot-melt, can also be used, so that sheet 5 of the rim 4 and the surface of the carbon fibers bonded fixed partial melting . 此外,在修整步骤中,也可对碳纤维轮圈4整体进一步进行研磨、上漆(金油)等其他表面修饰加工流程,使碳纤维轮圈4可具有较佳的表面质感。 Further, in the trimming step, may further be carbon fiber rims 4 integrally polishing, lacquering other surface (the oil) and other modified processing flow of the carbon fiber rim 4 may have a preferred surface texture.

[0051] 本实施例中所提供的碳纤维轮圈4是供组装管形轮胎使用而不具有扣唇,然而, 在本发明其他可能的实施例中,也可改变该外模1或该模穴的形状,而使该碳纤维轮圈成形出扣唇。 [0051] The present embodiment of the carbon fiber rim 4 is provided in the embodiment for assembling a tubular tire without a fastening lip, however, in other possible embodiments of the present invention may also be a change of the outer mold or the cavity shape, so that the carbon fibers forming the snap rim lip.

[0052] 通过上述技术方案,本发明在生产自行车轮圈时,利用对应轮圈外形的内模为媒介,以利于气袋膨胀过程中迫使内模均匀地朝外扩撑,而非传统气袋充气会朝轮圈两侧过度挤压模式,自然可令本发明制成的碳纤维轮圈整体厚度均匀,质量稳定并具有较高的结构强度。 [0052] The above technical solution, the present invention is in the production of bicycle rim, using a mold corresponding to the outer shape of the rim of the media, in order to facilitate the expansion process of the air bag forces the inner mold stays evenly spread outwardly, rather than the traditional bag inflatable excessively squeeze mode to the rim on both sides, so that the carbon fibers may be natural entire thickness of the rim of the present invention is made uniform and stable quality and has a high structural strength.

[0053] 再者,本发明在进行碳纤维复合材的排叠时,该内模即提供对应轮圈的既定外形, 加上可挠性的内模较传统的气袋略硬,故可提供碳纤维复合材(布)精确且均匀地叠贴于内模表面的优点。 [0053] Further, the present invention during the exhaust stack of a carbon fiber composite material, providing the inner mold corresponding to the predetermined shape of the rim, the mold together with the flexible bag slightly more traditional hard, it can provide a carbon fiber composite material (fabric) laminated uniformly and precisely affixed to the inner surface of the mold advantages. 更明确地说,具有可挠性的内模,可提供碳纤维复合材叠贴同时进行定位,因而可以大幅提商碳纤维复合材置贴作业速度,提商整体生广效率。 More specifically, a flexible mold, a carbon fiber composite material can be provided simultaneously positioning bundle paste, it is possible to provide commercially significant carbon fiber composite material affixed to opposite operating speed, the overall health providers provide wide efficiency.

[0054] 此外,本发明在充气时不需将气袋分段充气,即可获得质量稳定的碳纤维轮圈,可进一步提高生产效率;总结上述特点,本发明实为具有进步的功效。 [0054] Further, the present invention is not required when inflated the inflatable bag segment, stable quality can be obtained a carbon fiber rims, the production efficiency can be further improved; characteristics summarize the above, the present invention is a solid having a progressive effect.
