新型岩石深孔刻槽刀具设计

摘    要

现今中国的石材工业高速发展，对石材的需求量日益增加。而怎样开采出无内伤，无裂缝，并且规格合理的石材，是我们比较感兴趣的话题。目前国内的石材加工方法大多数还是使用刻槽爆破的方法。所谓刻槽爆破就是利用机械或者水流等方法在孔壁预计的开裂方向上刻轴向槽，使爆炸能对所刻介质的开裂位置，开裂方向进行控制的一种断裂控制爆破方法。
要进行刻槽爆破就必须用一种方法在孔壁上刻出轴向槽。目前国内的使用的主要的方法就是使用冲击式刻槽工具在孔壁上刻出轴向槽，但是这种方法有许多缺点。比如刀具容易损坏，刀具不易拔出等等。本问就是在这种背景下，提出一种新的刻槽的方法：风动潜孔刻槽。
顾名思义，“风动潜孔刻槽”就是利用风动马达作为动力，经过一系列的传动来带动一个高速旋转的金刚石锯片的转动，从而达到刻槽的目的。该设计最终实现使刀具高速垂直方向的旋转，取代了以往的上下冲击式的刀具，这样就弥补了后者的一些缺点，提高了刻槽效率，提高了槽线质量，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
