【摘要】：為了獲得高性能的電鍍金剛石鋸絲,實(shí)驗(yàn)研究了懸砂法制備表面磨粒群螺旋排布鋸絲的電鍍工藝,分析了預(yù)鍍陰極電流、上砂陰極電流密度與上砂時(shí)間對鋸絲復(fù)合鍍層外觀質(zhì)量與鋸絲表面磨粒分布情況的影響規(guī)律,并采用試制鋸絲進(jìn)行了鋸切實(shí)驗(yàn)。研究結(jié)果表明,鍍底層的陰極電流密度為5.0A/dm2時(shí),鍍層與鋼絲基體表面有著良好的結(jié)合強(qiáng)度;上砂階段采用陰極電流密度為5.0A/dm2,其電鍍時(shí)間為7~8min,可得到良好的鍍層和磨粒分布效果。鋼絲基體預(yù)鍍前在表面繞絕緣線,合理地選擇工藝參數(shù)可以獲得磨粒群在鋼絲基體表面螺旋排布的基本結(jié)構(gòu),試制的新型鋸絲在鋸切中具有良好的容屑與排屑效果。
[Abstract]:In order to obtain high performance electroplated diamond saw wire, the electroplating process of surface abrasive group spiral arrangement saw wire prepared by suspended sand method was studied experimentally, and the cathodic current of pre-plating was analyzed. The effect of cathode current density and sand loading time on the appearance quality of saw wire composite coating and the distribution of abrasive particles on the surface of saw wire were studied. The results show that when the cathodic current density of the coating layer is 5.0A/dm2, the bonding strength between the coating and the steel wire substrate surface is good, and when the cathode current density is 5.0 A / dm ~ (2) and the electroplating time is 7 ~ 8 min, a good distribution effect of coating and abrasive particles can be obtained. The basic structure of spiral arrangement of abrasive particles on the steel wire substrate can be obtained by selecting the technological parameters reasonably before pre-plating on the steel wire substrate. The new type of saw wire produced by trial production has a good effect of holding and removing chips in the sawing process.
