新型巖石深孔刻槽刀具設計

摘    要

現(xiàn)今中國的石材工業(yè)高速發(fā)展，對石材的需求量日益增加。而怎樣開采出無內(nèi)傷，無裂縫，并且規(guī)格合理的石材，是我們比較感興趣的話題。目前國內(nèi)的石材加工方法大多數(shù)還是使用刻槽爆破的方法。所謂刻槽爆破就是利用機械或者水流等方法在孔壁預計的開裂方向上刻軸向槽，使爆炸能對所刻介質(zhì)的開裂位置，開裂方向進行控制的一種斷裂控制爆破方法。
要進行刻槽爆破就必須用一種方法在孔壁上刻出軸向槽。目前國內(nèi)的使用的主要的方法就是使用沖擊式刻槽工具在孔壁上刻出軸向槽，但是這種方法有許多缺點。比如刀具容易損壞，刀具不易拔出等等。本問就是在這種背景下，提出一種新的刻槽的方法：風動潛孔刻槽。
顧名思義，“風動潛孔刻槽”就是利用風動馬達作為動力，經(jīng)過一系列的傳動來帶動一個高速旋轉(zhuǎn)的金剛石鋸片的轉(zhuǎn)動，從而達到刻槽的目的。該設計最終實現(xiàn)使刀具高速垂直方向的旋轉(zhuǎn)，取代了以往的上下沖擊式的刀具，這樣就彌補了后者的一些缺點，提高了刻槽效率，提高了槽線質(zhì)量，并降低了石材加工的成本。

ABSTRACT

China's stone industry today's rapid development, increasing the demand for stone. And how to non-exploitation of internal injuries, no cracks, specifications and reasonable Stone is interested in the topic. At present the domestic stone processing methods or the use of most of the bursting of the groove method. The bursting of the so-called groove is the use of methods such as mechanical or water hole in the wall is expected to crack the direction of the axial trough carved, inscribed by the explosion of media to the cracking of location, direction and control of cracking a method of controlled blasting.
To carry out groove on the bursting of a method must be used in wall-Kechu axial slot. At present the domestic use of the main method is the use of impact-groove hole in the wall Kechu tool axial slot, but this approach has many shortcomings. Tool easy to damage, for example, difficult to pull out the knives and so on. This question is in this context, a new groove approach: Wind-driven down-the-hole groove.
As the name suggests, "Wind-driven down-the-hole groove" is the use of pneumatic motor as the driving force, after a series of transmission led to a high-speed rotation of the diamond saw blade rotation, the groove so as to achieve the objective. The final design tool to achieve high-speed vertical direction of rotation, replacing the previous upper and lower impact of knives, so that the latter make up for some shortcomings, improve the efficiency of the groove and improve the quality of the trough line, and reduce the processing of stone Cost.

Key words：Groove blasting; axial groove; rotating cutter; pneumatic down-the-hole groove
