星火熱熔鉆產(chǎn)品詳細(xì)介紹

    熱熔鉆工藝是在金屬薄板或管材上一次加工出孔和襯套的無(wú)屑加工技術(shù)，完全替代了在薄壁工件上焊(鉚)接螺母的工藝。熱熔鉆采用耐磨、耐高溫的硬質(zhì)合金材料制成。當(dāng)?shù)毒吆凸ぜ�接觸時(shí)，高的轉(zhuǎn)速（1000~3500），和適當(dāng)?shù)妮S向推力（進(jìn)給力），使鉆頭和金屬之間發(fā)生劇烈摩擦，瞬間達(dá)到攝氏650°750°的溫度。鉆頭附近區(qū)域的金屬迅速軟化，繼續(xù)施加軸向壓力，快速在工件上、下表面擠壓出約是初始板材3倍厚度的凸臺(tái)和襯套。整個(gè)過(guò)程只需要2-6秒的時(shí)間。對(duì)于需要光滑連接表面或倒角孔的加工，可采用平面型星火Flowdrill鉆頭，以切除在工件表面形成的凸臺(tái)。襯套可以用作軸承支座，分叉喉道焊接口等用途，也可以攻絲，以供螺紋連接。螺紋為滾壓成形，加工出來(lái)的螺紋能承受更高的拉力和扭。
    星火Flowdrill無(wú)屑鉆削工藝適合加工普通鋼材、不銹鋼、鋁、銅、和其它各種具有延展性的工件材料，也可以加工電鍍過(guò)的工件。可用于手工臺(tái)鉆或CNC數(shù)控機(jī)床，所需功率1.53.5kW，主軸轉(zhuǎn)速10003500r/min。根據(jù)被加工孔徑、工件材料和厚度的不同，選用的切削參數(shù)也有所不同。
    優(yōu)勢(shì)：高效，經(jīng)濟(jì)，節(jié)省材料，并且加工出的工件比較美觀。

Flowdrilling simultaneously perforates and forms bushings in thin metal using frictional heat produced by high rotational speeds and axial pressure.cost effective replacement for threaded and riveted nut applications surfaces in thin materials .it will produce very precise and very strong threads withhigh torque specifications.
  The process as follows:
1.Plasticizing and displacement of material，using high speed rotation and pressure
2.Formation of bushing that can be 3 times of the original material thickness
3.Formation of the thread using the cold tapping method
  Advantages:
Flowdrill and Flowtap processes can be adapted to any CNC center or manual machining units .
Several applications is possible ,as steel （up to 700 N/mm2 tensile strength）,non-ferrous metale ,aluminium (less than 5% Si),stainless steel,acid resistant steel etc.
Very exact process with small tolerance divergences.
Improved quality，time and money savings.
