    济南装载机整机涂装线存在哪些问题?
    发布时间:2014-7-31 17:41:44    浏览:242次

    由于国家加大基础设施方面的投入,使装载机行业进入产销两旺的大好局面,几个主要装载机生产企业均创纪录地达到了各自的最高产量。同时各生产厂家均在外观质量上进行了改进,油漆方面主要是对装载机进行了套色作业,即将装载机的外观颜色分成两部分,改变了装载机长期以来的单一颜色。

    一、随着装载机产量的提高,以及外观油漆套色作业的大量使用,整机涂装线在使用过程中就出现了几个问题:
    1、套色作业使得装载机外表面的喷漆时间缩短(一次喷漆面积减少了),而屏蔽时间非但没有缩短,还有加长的趋势,使得整个流水线的节拍发生了变化,在产量低的时候还影响不大,只不过一些工位增加了等待时间,产量增大后就需要将部分屏蔽工作放在线下进行。
    Chromatic paint job makes the outer surface of the loader shorter time (one spray area reduction), but the time has not only shortened the shield, as well as lengthen the trend, making the entire pipeline to the beat changed, when it comes to the low yield little impact , but increased the number of stations waiting time, increases the yield after the working part of the shielding needed to be put online.
    2、由于整个生产线的节拍缩短,而水迹烘干室有一个升温的过程,这样一来温度刚升到有时甚至还没有升到规定温度就需要转到下一工位,根本就不能发挥作用,而水迹烘干室是通过式的,打开门后温度立即下降到环境温度。
    Since the entire production line to the beat shortening, and water stains drying room has a warming process, so that the temperature rise is sometimes just not even need to rise to a predetermined temperature to the next station, simply can not play a role, but traces of water by drying room type, the temperature dropped immediately after opening the door to the ambient temperature.
    3、烘干室也存在和水迹烘干室一样的问题,不能充分发挥烘干作用。
    Drying room there are traces of water drying room and the same problem, can not give full play to the drying effect.
    4、各室体的大门采用气动门,开关的时间较长,完全打开或完全关闭约3-5min,在整个节拍较长(45min)时还不觉得,在节拍缩短后就显得有点过长了。
    Each room door body pneumatic doors, switch a long time, fully open or fully closed about 3-5min, in whole beat long (45min) when not think, in the beat is a little too long after shortening.

    二、针对这种情况,建议采取以下措施:
    1、装载机清洗除油后,采取自然凉干的方式,注意保持均衡生产,若天气不好时,就利用晚上的时间进行烘干。
    After loaders cleaning degreasing, take natural dry way to keep the balanced production, if the weather is bad, on the use of night time for drying.
    2、生产线作业时,水迹烘干室不工作,将屏蔽的大部分工作都放在线下进行。
    When the production line operations, water stains drying room does not work, most of the work will be screened are put under online.
    3、喷漆时所有室体的门都不关,以节省时间。这样一来容易造成漆雾飞散到喷漆室旁的屏蔽室和流平室。
    When painting the door is not shut all the chamber body, to save time. As a mist is likely to cause scattered to the shielded room and leveling room next to the spray booth.
    4、新建一个大的?;镉糜谕7排绾闷岬淖霸鼗?,并在此进行补漆和装潢作业;气温低时,就利用晚上的时间进行烘干。
    Create a large hangar for a good spray paint parked loader, and in this make-up painting and decorating jobs; temperature is low, the use of night time for drying.
    5、用白铁皮制作一些屏蔽玻璃的挡板,节约屏蔽玻璃的时间。
    With white metal to produce some shielding glass bezel, time-saving glass shield.
