| 摘 要： | 压射冲头是压铸中极其重要的一个辅件,其寿命的长短直接影响到压铸生产的效率与成本。以HT200冲头为对象,研究了一种间歇式冷却水控制方法,试验了通水冷却时间、配合间隙对压射冲头使用寿命的影响。结果表明,配合间隙与冷却时间对压射冲头的使用寿命影响很大,当配合间隙控制在0.08～0.16mm时,冲头的使用寿命较长。在上述配合间歇下,冲头冷却时间为35s时,冲头的使用寿命最长,可达1600模次左右。

| Abstract: | Injection punch heads as a key assistant part in die casting machine,its service lif directly affected the manufacturing efficiency and cost.A new intermittent cooling method was presented for the injection punch heads made by HT200.Effects of tolerance and cooling time on service life of the injection punch heads were analyzed.The results reveal that service life of the heads is closely related to the tolerance and cooling time.The punch heads exhibits a longer service life with tolerance at 0.08~0.16 mm.F... |
