吉林省旭东科技有限公司

采暖散热器生产工艺   一、对于高密齿和舌比大的模具试模时,支铝棒必须是150-200mm的短铝棒或纯铝棒。      二、试模前,必须调整好挤压中心,挤压轴、盛锭筒和模座出料口在一条中心线上。      三、在试模和正常生产过程中,铝棒加热温度要保证在480-520℃之间。      四、模具加热温度按常规模具温度,控制在480℃左右,直径200mm以下的平模保温时间不得少于2小时,如果是分流模保温在3小时以上;直径大于200mm以上的模具保温4-6小时,以保证模具芯部温度与外部温度的均匀。      五、在试模或生产前,必须用清缸垫清理干净盛锭筒内胆,并查看挤压机空运行是否正常。      六、试模或刚开始生产时,挤压机自动档关掉,各段开关归零位。从小压力开始慢慢的起压,出料大概3-5分钟,铝填充过程时主要控制好压力。压力控制在100Kg/cm2以内,电流表数据为2-3A以内,一般80-120Kg/cm2可以出料,之后才可慢慢的加速,正常生产时挤压速度以压力小于120Kg/cm2为准。      七、模具在试模或生产过程中,如发现堵模、偏齿、快慢偏差太大等现象时要立刻停机,并以点退的方式卸模,避免模具报废。      八、在试模或生产过程中,出料口必须通畅,垫支或夹具松劲根据出料情况合理掌握。随时观察发现异常情况,及时处理,该停机时要立即停机。      九、矫直过程中,要认%*网上博#菜公司导航AG亚游国际,ag荷官揭秘%&真检测前后变化,操作规范,用力适度,严保产品质量。      十、按照生产计划单要求合理定尺,锯切时,锯齿进料速度不能太快,避免打伤端头,端%*k7娱乐城备用新手咋玩,代理什么样提成?%&头必须钳正,去掉飞边和毛刺。      十一、装筐要规范,包括垫条要摆放合理,避免损伤型材。      十二、型材时效温度控制在190±5℃,保温2.5-4小时,出炉后进行风冷。
