摘 要:火焰切割機(jī)是利用各種可燃?xì)怏w和氧氣的燃燒來(lái)切割鋼坯的?；鹧媲懈顧C(jī)的主要特點(diǎn)是:投資費(fèi)用比較少，切割設(shè)備的外形也較小，切縫較平整，并不受鑄坯溫度和斷面大小的影響，特別是大斷面的鑄坯，其優(yōu)越性更明顯，但切割時(shí)間較長(zhǎng)，切縫又寬，切口處的金屬損耗嚴(yán)重，污染也嚴(yán)重。 火焰切割機(jī)通常由切割機(jī)構(gòu)、同步機(jī)構(gòu)、返回機(jī)構(gòu)、斷面檢測(cè)器、定尺機(jī)構(gòu)及氧、乙炔管路系統(tǒng)等部分組成。切割機(jī)構(gòu)是火焰切割機(jī)的關(guān)鍵部分，它主要由切割槍和傳動(dòng)機(jī)構(gòu)組成。同步機(jī)構(gòu)是指使切割小車(chē)與連鑄坯同步運(yùn)行的機(jī)構(gòu)。切割小車(chē)是在與鑄坯無(wú)相對(duì)運(yùn)動(dòng)的的條件下切割鋼坯的。返回機(jī)構(gòu)是指采用普通小車(chē)運(yùn)行機(jī)構(gòu)。定尺機(jī)構(gòu)是由氣缸推動(dòng)測(cè)量輥，使之頂在鑄坯的下面，靠摩擦力使之轉(zhuǎn)動(dòng)，觸發(fā)脈沖器發(fā)出脈沖信號(hào)。 關(guān)鍵詞：火焰切割機(jī) 切割機(jī)構(gòu) 同步機(jī)構(gòu) 返回機(jī)構(gòu) 定尺機(jī)構(gòu)
Abstract:Flame cutting machine is to use a variety of the combustion of combustible gas and oxygen to cut billet. The main characteristics of the flame cutting machine is: low investment cost, cutting equipment of small shape, kerf smooth, is not affected by the billet temperature and section size, especially for large section casting, its superiority is obvious, but the cutting time is longer, the slit is wide, the loss of metal incision is serious, also serious pollution. The cutting mechanism is a key part of the flame cutting device. It is mainly composed of a gun and gear cutting. A synchronization mechanism refers to the cutting trolley and continuous casting slab synchronization operation mechanism. Cutting the trolley and slab without relative motion conditions cutting billet. The return mechanism refers to the use of ordinary car movement organization. The positioning mechanism is driven by the cylinder measuring roll, so that the top below the billet, friction on the rotating the. Using pulse emitted pulse signal. Keywords: flame cutting machine; cutting mechanism; mechanism of synchronization; mechanism of return ; sizing mechanism. |
