Description

吹瓶机用铝合金模具的表面硬化工艺
技术领域
本发明涉及饮料瓶加工设备领域，更特别涉及一种吹瓶机用铝合金模具的表面硬化工艺。
背景技术
吹瓶机在工作过程中，与饮料瓶直接接触的模具是整机中磨损最为严重的部件之一，特别是模具型腔的表面。在强大气流的喷吹过程中，模具型腔的表面容易产生磨损，出现凹坑，而模具型腔的表面与饮料瓶的表面相接触，磨损后的凹坑直接影响饮料瓶的质量，因此，型腔的耐磨程度直接决定了饮料瓶的质量。
发明内容
本发明目的是提供一种吹瓶机用铝合金模具的表面硬化工艺。
为达到上述目的，本发明采用的技术方案是：
一种吹瓶机用铝合金模具的表面硬化工艺，包括以下步骤：
（a）对铝合金模具的型腔表面进行抛光处理，并将抛光后的铝合金模具放入内装有电解液的氧化槽内进行硬质阳极氧化处理，
其中，硬质阳极氧化处理使用的氧化电流由电流密度为0.5~3.5A/dm2的交流电流、电流密度为1.2~4.5A/dm2的直流电流及脉冲电流叠加而成；
其中，电解液为包括无机酸和有机酸的混合溶液；
（b）在氧化处理后的在铝合金模具的型腔边缘的分型线处涂抹弱导电膜；及
（c）对氧化处理后的铝合金模具的型腔表面再进行抛光处理。
进一步地，在步骤（a）中，无机酸为硫酸；
优选地，在步骤（a）中，无机酸的自身质量浓度为17%~19%。
进一步地，在步骤（a）中，有机酸为二羧基乙酸。
优选地，在步骤（a）中，有机酸的自身质量浓度为4%~6%。
进一步地，在步骤（a）中，氧化槽内的温度为-8~-2℃。
优选地，在步骤（a）中，脉冲电流的频率40-60赫兹，占空比为20%-60%。
优选地，氧化处理后在铝合金模具的型腔的表面形成一层厚度为30~80µm的氧化层。
由于上述技术方案运用，本发明与现有技术相比具有下列优点和效果：
本发明通过在铝合金模具的型腔表面氧化一层硬化层，使得型腔表面更加耐磨、耐腐蚀，并且硬化层与型腔表面结合牢固，不易脱落。
附图说明
附图1为本发明的铝合金模具的示意图。
其中：1、铝合金模具；2、型腔；3、氧化层。
具体实施方式
下面结合附图及实施案例对本发明作进一步描述：
一种吹瓶机用铝合金模具1（如图1所示）的表面硬化工艺，包括以下步骤：
（a）对铝合金模具1的型腔2表面进行抛光处理，并将抛光后的铝合金模具1放入内装有电解液且温度范围控制在-8~-2℃的低温氧化槽内进行硬质阳极氧化处理，其中：
氧化处理的氧化电流由电流密度为0.5~3.5A/dm2的交流电流、电流密度为1.2~4.5A/dm2的直流电流及脉冲电流相叠加而成，其中脉冲电流的频率为40-60赫兹，占空比的范围为20%-60%；以此控制氧化层生成的速度和氧化层的结构；
电解液为自身质量浓度为18%的硫酸和自身质量浓度为5%二羧基乙酸的混合溶液；
（b）在氧化处理后的铝合金模具1的型腔2边缘的分型线处涂抹弱导电膜，该弱导电膜为由油脂形成的弱导体；
（c）对氧化处理后的铝合金模具1的型腔2表面再次进行抛光处理。
氧化后在铝合金模具1的型腔2的表面形成一层厚度为30~80 µm的氧化层3，在本实施例中，所形成的氧化层的厚度为60um，其中一半渗入铝合金基材，一半生长出来，所以该氧化层与机体结合非常牢固，不易脱落；此外，氧化层表面硬度可以达到HV300-500，非常耐磨、耐腐蚀。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
