Problems solved by technology

However, in the long-term production process, it is found that the waste rate of diamond saw blades produced by this process is extremely high, reaching a probability of 30%-35%, which seriously affects the production quality and is difficult to control production costs, especially in the pressing process. , the pressed saw blades often break, and the subsequent processes cannot be carried out at all, and the workers have to deal with these waste products, which seriously affects the work efficiency
Moreover, in the existing processing technology, pre-alloyed powder is generally added, but if the pre-alloyed powder is added too little, it will not be sharp enough. If too much is added, although the cutter head is sharp, the forming degree during pressing is very poor.

Embodiment Construction

[0014] The production process of the diamond saw blade pressed and formed by granular powder, the steps include: taking copper powder, iron powder, tin powder, nickel powder and cobalt powder as raw materials, adding liquid paraffin for mixing and stirring, and then pressing, sintering and post-processing The key is: the specific steps of the manufacturing process include:

[0015] a. Proportion raw materials by weight percentage, copper powder 20%-30%, iron powder 10%-25%, tin powder 5%-7%, nickel powder 4%-7%, cobalt powder 10%-15%, pre Alloy powder 25-32%;

[0016] b. Add liquid paraffin to the above raw materials, mix and stir for 4-6 hours;

[0017] c. Agglomerate the mixed slurry in cobalt powder, stop the agglomeration when the diameter of the particles is 0.1-0.2mm, screen the particles out with the aid of a sieve, and then dry them to form diamond particles;

[0018] d. Putting the above diamond particles into a pressing mold for pressing to form a regular saw blade...

Abstract

Disclosed is a production process of a diamond saw blade formed by compressing granular powders. The production process includes steps of using a copper powder, an iron powder, a tin powder, a nickel powder and a cobalt powder as raw materials, adding liquid paraffin for mixing and stirring, and then performing procedure steps of compressing, sintering and post-treating. The production process is characterized in that an agglomerating procedure is performed before a compressing procedure, and the powder raw materials are agglomerated to be granular and then compressed. According to experiments, the production process is obvious in effects, no defect is produced after the compression, and the yield of the finished diamond saw blade can reach above 97%.

Description

technical field [0001] The invention belongs to the technical field of production technology of diamond products, and relates to a production process of a diamond saw blade, in particular to a process step that can greatly improve the yield of the saw blade. Background technique [0002] The current diamond saw blade manufacturing process is relatively mature. The general process steps include firstly mixing the powder of raw materials and then pressing, followed by sintering and post-processing. However, in the long-term production process, it is found that the waste rate of diamond saw blades produced by this process is extremely high, reaching a probability of 30%-35%, which seriously affects the production quality and is difficult to control production costs, especially in the pressing process. , The pressed saw blades often break, and the subsequent processes cannot be carried out at all, and the workers have to deal with these waste products, which seriously affects th...
