在長(zhǎng)期使用塑料托盤表面時(shí),由于摩擦頻繁,可能會(huì)產(chǎn)生一些毛刺。雖然大多數(shù)塑料托盤與貨物接觸,不需要太注意表面的平整度,但它影響美觀,有哪些方法可以去除上面的毛刺。

翻邊毛刺是更常見的一種。它基本上是彎曲的而不是剪切的碎片,從而產(chǎn)生更大的毛刺。這種類型的毛刺也稱為出口毛刺,因?yàn)樗ǔJ窃诙嗣驺娤鞫瞬啃纬傻摹?/div>

二、撕裂毛刺
2、Tearburr
撕裂毛刺是由工件材料的撕裂而不是剪切引起的。

三、去毛刺
3、Deburring
切斷毛刺是工件在分離和切割完成之前從坯料落下時(shí)留下的材料的投影。
Cuttingburristheprojectionofmaterialleftbyworkpiecewhenitfallsfromblankbeforeseparationandcutting.
四。泊松發(fā)
Four.Pinehair
泊松毛刺是由于材料在壓縮過程中發(fā)生側(cè)向膨脹而引起的性塑性變形。

去毛刺類型
Deburringtype
盡管有許多類型的去毛刺工藝,下面描述的那些特別用于塑料材料。
Althoughtherearemanytypesofdeburringprocesses,thosedescribedbelowareparticularlyusedforplasticmaterials.
一、手工去毛刺
1、Manualdeburring
手動(dòng)去毛刺是更常見的去毛刺類型,因?yàn)樗蟮撵`活性。手工去毛刺的工具通常比較便宜。手動(dòng)去毛刺允許立即檢查和更佳質(zhì)量,而無需強(qiáng)制加工材料。手工去毛刺通常用于塑料、金屬和其他材料。這一過程的消極一面是維持人員費(fèi)用和人為失誤的可能性。

二、低溫脫毛去屑
2、Depilationatlowtemperature
低溫切屑去除和去毛刺是去除注塑件和機(jī)械加工件飛邊更有效和更廉價(jià)的工藝之一。使用液氮,將成分降低到允許材料變脆的溫度。然后,使用低溫除屑器,可以在不改變零件表面光潔度的情況下輕松去除飛邊和毛刺。該工藝可在多種材料上完成,包括橡膠、塑料、硅膠和輕金屬壓鑄。橡塑件的低溫切屑了模具脫模后在模具上發(fā)現(xiàn)的不必要的模具飛邊。閃存通常位于模具在生產(chǎn)過程中液體模具材料從模具型腔逸出時(shí),模具在一起或分開的區(qū)域。低溫切屑去除不會(huì)降低或損壞部件。僅閃光并保留零件的形狀。邊緣保持鋒利,凹陷區(qū)域完全沒有閃光。塑料可以精確地。

三、機(jī)械脫毛
3、Mechanicaldepilation
這是一個(gè)機(jī)械磨削或磨削加工零件的過程。它可用于PVC材料,用手去除時(shí)不會(huì)產(chǎn)生光滑的光潔度。這一過程可能很耗時(shí),不能保證完工質(zhì)量。
