簡(jiǎn)單介紹
英制鋼絲螺套是一種新型的螺紋緊固件，是由高精度表面光潔的冷軋菱形不銹鋼絲**加工而成的一種彈簧狀內(nèi)外螺紋同心體。鋼絲螺套還可以在原基體上的螺紋脫扣或亂牙時(shí)，作為修復(fù)手段，而不致造成整個(gè)基體報(bào)廢，并且維修方便，快速經(jīng)濟(jì)。
英制鋼絲螺套的詳細(xì)介紹
英制鋼絲螺套簡(jiǎn)介：
英制鋼絲螺套（簡(jiǎn)稱螺套）是為保護(hù)有色金屬螺紋孔而發(fā)展的嵌入物，適用于螺紋連接。旋入并緊固在被連接件之一的螺紋孔中，形成標(biāo)準(zhǔn)內(nèi)螺紋，螺栓（或螺釘）再擰入其中。以冷軋不銹鋼線制造成螺旋狀內(nèi)外同心體螺紋線圈，橫切面呈菱形，形狀類似于螺旋彈簧，具有較高的硬度及較好的表面粗糙度。
英制鋼絲螺套的作用：
英制鋼絲螺套主要用于螺絲孔的維修和要求較高的螺絲孔的制造。特別是在防止成本高昂的機(jī)器由于螺絲孔的損壞而無法正常使用方面，發(fā)揮著巨大作用。內(nèi)螺紋常因種種原因而損壞，如脫扣、爛牙、磨損、腐蝕、生銹等等。內(nèi)螺紋損壞有時(shí)會(huì)造成嚴(yán)重?fù)p失，輕者影響裝配過程和裝配質(zhì)量，重者能造成整個(gè)大件報(bào)廢，鋼絲螺套為您提供了一套簡(jiǎn)易而可靠的內(nèi)螺紋修復(fù)方法，修補(bǔ)后的螺紋，將比原來的螺紋更加優(yōu)越。對(duì)于強(qiáng)度較低的零件如鋁、鎂合金、銅、鑄鐵、鋼件、塑料、密度板和木材、玻璃鋼，這一點(diǎn)尤其明顯。安裝鋼絲螺套使用專用的絲錐及安裝工具攻絲和安裝，螺套裝于螺孔或螺母中，有減輕螺紋牙受力不均和抗沖擊振動(dòng)的作用，可以提高螺紋的疲勞強(qiáng)度，減少螺紋的磨損和抗腐蝕性能。延長(zhǎng)螺孔壽命。
