Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 As shown, the distributor B of the present invention includes a sealed cavity 1 and a template 2 . The size of the lower surface of the template 2 is the same as the size of the cutter head, such as image 3 As shown, and the lower surface of the template 2 is provided with a plurality of countersunk holes 21 for accommodating a diamond 7 respectively, and the plurality of countersinks 21 are distributed according to the cutting mechanism of the cutter head, that is, the countersinks 21 are in different positions. The arrangement on the template 2 is not the same to suit different cutter heads. The sealed cavity 1 is arranged above the upper surface of the template 2, and the bottom of the counterbore 21 is provided with a through hole 22 extending to the upper surface of the template 2 for ventilation. Since...

Abstract

The invention provides a method for positioning and distributing diamonds in a tool bit and a distributing device. The distributing device comprises a template and a sealing cavity body, wherein the dimension of the lower surface of the template is identical to that of the tool bit, the lower surface of the template is provided with a plurality of counterbores which are distributed according to a cutting mechanism of the tool bit, each counterbore can contain one diamond, and the sealing cavity body is arranged above the upper surface of the template. The bottoms of the counterbores are provided with through holes used for ventilation and extending to the upper surface of the template, the sealing cavity body is communicated with the counterbores through the through holes, and the sealing cavity body is provided with a port for pumping vacuum and inputting airflow. The distributing device can effectively and appropriately distribute the diamonds in three-dimensional space of the diamond tool bit with low cost.

Description

technical field [0001] The invention relates to a preparation method of a diamond tool bit, in particular to a method for realizing directional arrangement of diamonds in the bit and a distributor thereof. Background technique [0002] Diamond tool is a special tool with the diamond with the highest hardness and the strongest abrasive resistance in nature as the cutting unit. A general diamond tool consists of two parts, a metal substrate and a diamond tip. The characteristic of the cutter head made by the traditional method is that the diamonds are randomly distributed in the cutter head, and it is easy to form a diamond accumulation area or a rare area. In the accumulation area, the cutting force of the diamond is too small, and it is not easy to produce an edge; in the diamond-sparse area, the concentration of diamond is too low, and the single particle bears a huge working load, so that the diamond particles are broken by the impact force and fall off prematurely, and i...
