Description
Technical Field
The invention relates to the field of brazed diamond cutters, in particular to a clamping device for a brazed diamond hole drilling and glue distributing cloth.
Background
Most of the traditional diamond tools are made by a multilayer sintering process, a single-layer electroplating sintering process and the like, the exposure height of diamond particles of the prepared diamond tool is generally not more than 1/3 of the particle size, and the processing performance is poor; and the diamond particles are only mechanically wrapped in the matrix, so that the diamond particles are easy to fall off, the service life is short, and the working efficiency is low.
Brazed diamond tools are a manufacturing method of high performance diamond tools emerging in recent years, and have been developed in the late 80 s of the 20 th century. Originally foreign researchers attempted to apply the brazing process to the manufacture of new single layer diamond tools. During high-temperature brazing, chemical reactions occur between the diamond abrasive particles and the brazing filler metal as well as between the brazing filler metal and the steel matrix, so that more stable chemical metallurgical bonding is formed, and the connection strength among the steel matrix, the diamond abrasive particles and the brazing filler metal alloy can be greatly enhanced. The exposed height of the diamond abrasive can reach 2/3 of the abrasive, so that the cutting tool has good chip removal performance, high processing efficiency and long service life.
At present, enterprises at home and abroad start to produce brazed diamond cutters in small batches, but the production links mainly depend on manual work or semi-manual work, and the defects of uneven adhesive distribution and material distribution, low production efficiency, poor product quality and the like are caused. The uneven distribution of diamond particles not only seriously affects the service life of the cutter, but also affects the quality of the processed product.
The product quality of the brazed diamond tool can be ensured only by realizing the automatic distribution of the brazed diamond tool and ensuring the uniform distribution of diamond particles and brazing materials; meanwhile, only by realizing the automation of the material distribution, the automatic production and the industrial application of the brazed diamond cutter can be popularized. Therefore, how to realize automatic distribution is the most important factor limiting the high-quality and large-scale production of the brazed diamond cutter. The clamping device of the brazing diamond tool is the most important part of the most basic automatic production.
