株洲熱鑽(熱熔鑽)產品詳細介紹
|
熱鑽(熱熔鑽)工藝是在金屬薄板或管材上一次加工出孔和襯套的無屑加工技術,完全替代了在薄壁工件上焊(鉚)接螺母的工藝。熱熔鑽採用耐磨、耐高溫的硬質合金材料製成。當刀具和工件接觸時,高的轉速(1000~3500),和適當的軸向推力(進給力),使鑽頭和金屬之間發生劇烈摩擦,瞬間達到攝氏650°~750°的溫度。鑽頭附近區域的金屬迅速軟化,繼續施加軸向壓力,快速在工件上、下表面擠壓出約是初始板材3倍厚度的凸台和襯套。整個過程只需要2-6秒的時間。對於需要光滑連接表面或倒角孔的加工,可採用平面型Flowdrill鑽頭,以切除在工件表面形成的凸台。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,加工出來的螺紋能承受更高的拉力和扭。
熱鑽工藝適合加工普通鋼材、不鏽鋼、鋁、銅、和其它各種具有延展性的工件材料,也可以加工電鍍過的工件。可用於手工台鑽或CNC數控機床,所需功率1.5~3.5kW,主軸轉速1000~3500r/min。根據被加工孔徑、工件材料和厚度的不同,選用的切削參數也有所不同。 熱鑽的 優勢:高效,經濟,節省材料,並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. |
