       随着市场金属铸(zhu)造业(ye)竟争激(ji)烈(lie)与环保压(ya)力的(de)加(jia)大,现各个铸(zhu)造生(sheng)产厂(chang)家不断的(de)从人工造型升级为全自动机械造(zao)型,但各个铸造生产厂家在具体改(gai)造升级过程(cheng)中选(xuan)用(yong)造型(xing)设备时存在很多(duo)的迷茫(mang)之处,针对此情况我(wo)司(si)总结(jie)了(le)一些经验以便客户(hu)在选(xuan)用(yong)造型(xing)机时能(neng)结(jie)合自(zi)己(ji)的产品(pin)类型(xing),选(xuan)择适合自(zi)己(ji)产品(pin)的造型(xing)线。

       根据所生产的零件大(da)小(xiao)、复杂程度、生产材质和批量的大(da)小(xiao)选择(ze)造型线。

       1、零件小、批量大,外(wai)型简单应优先(xian)选择生(sheng)产率高且辅助设备少占地(di)面(mian)积小的垂直(zhi)造型线(无芯或少芯更优先)和水(shui)平分(fen)型(xing)(xing)(xing)脱箱(xiang)压实(射压)造(zao)(zao)型(xing)(xing)(xing)线(xian)(xian)(xian) 如:建筑用(yong)扣件(jian)(jian),市政用(yong)井盖(gai)、井笓,水(shui)暖管件(jian)(jian)、消(xiao)防用(yong)沟槽、管件(jian)(jian)等(deng)。水(shui)平分(fen)型(xing)(xing)(xing)脱箱(xiang)造(zao)(zao)型(xing)(xing)(xing)线(xian)(xian)(xian)造(zao)(zao)型(xing)(xing)(xing)效率(lv)是(shi)(shi)垂(chui)直(zhi)(zhi)(zhi)造(zao)(zao)型(xing)(xing)(xing)线(xian)(xian)(xian)1/4,成套占地(di)面积是(shi)(shi)垂(chui)直(zhi)(zhi)(zhi)造(zao)(zao)型(xing)(xing)(xing)线(xian)(xian)(xian)的(de)2倍左右,但水(shui)平分(fen)型(xing)(xing)(xing)脱箱(xiang)造(zao)(zao)型(xing)(xing)(xing)线(xian)(xian)(xian)相比垂(chui)直(zhi)(zhi)(zhi)造(zao)(zao)型(xing)(xing)(xing)线(xian)(xian)(xian)生(sheng)产(chan)范围广,可适(shi)应多品(pin)种铸(zhu)件(jian)(jian)的(de)生(sheng)产(chan),但垂(chui)直(zhi)(zhi)(zhi)造(zao)(zao)型(xing)(xing)(xing)线(xian)(xian)(xian)在(zai)生(sheng)产(chan)高速旋转铸(zhu)件(jian)(jian)时(shi)(shi)与要求(qiu)高的(de)铸(zhu)件(jian)(jian)时(shi)(shi)存在(zai)一定的(de)缺陷(xian),此原因是(shi)(shi)由于垂(chui)直(zhi)(zhi)(zhi)造(zao)(zao)型(xing)(xing)(xing)线(xian)(xian)(xian)是(shi)(shi)垂(chui)直(zhi)(zhi)(zhi)分(fen)型(xing)(xing)(xing)垂(chui)直(zhi)(zhi)(zhi)浇(jiao)注,相对(dui)一模的(de)底(di)部(bu)铸(zhu)件(jian)(jian)与上(shang)部(bu)铸(zhu)件(jian)(jian)产(chan)生(sheng)浇(jiao)注压力(li)不同而产(chan)生(sheng)的(de)铸(zhu)件(jian)(jian)密度不同。

       2、零件(jian)复(fu)杂、质量(liang)要求高且多芯的(de)则应尽可(ke)能选用(yong)静压造(zao)(zao)(zao)型(xing)线(xian)(xian)与垂(chui)直(zhi)射砂水(shui)平(ping)分(fen)型(xing)的(de)水(shui)平(ping)线(xian)(xian),此(ci)两种造(zao)(zao)(zao)型(xing)线(xian)(xian)占地面积大,投资费用(yong)相对大,造(zao)(zao)(zao)型(xing)速度相比(bi)垂(chui)直(zhi)造(zao)(zao)(zao)型(xing)线(xian)(xian)要低,但所生(sheng)产的(de)铸(zhu)件(jian)精度高适(shi)应范围广(guang),适(shi)合生(sheng)产质量(liang)要求高的(de)汽车(che)配件(jian),出口铸(zhu)件(jian)等。

       在选用的(de)各种造(zao)(zao)(zao)型线(xian)(xian)(xian)时应与(yu)车间(jian)其它(制芯、熔炼(lian)、浇注、清理等(deng))的(de)设备技术(shu)(shu)水(shui)平(ping)、能(neng)力等(deng)相匹配,保证车间(jian)均衡流水(shui)生(sheng)产(chan)顺利进行。当然(ran),工(gong)厂设计时一般(ban)做法是先确定造(zao)(zao)(zao)型生(sheng)产(chan)线(xian)(xian)(xian),再以造(zao)(zao)(zao)型生(sheng)产(chan)线(xian)(xian)(xian)的(de)生(sheng)产(chan)能(neng)力要求,技术(shu)(shu)水(shui)平(ping),考(kao)虑熔炼(lian)、砂(sha)处理、浇注、制芯等(deng)工(gong)部,造(zao)(zao)(zao)型线(xian)(xian)(xian)应考(kao)虑两班制生(sheng)产(chan),以提高造(zao)(zao)(zao)型线(xian)(xian)(xian)的(de)利用率,造(zao)(zao)(zao)型线(xian)(xian)(xian)辅(fu)机(ji)的(de)技术(shu)(shu)水(shui)平(ping)和自(zi)动化程度应与(yu)造(zao)(zao)(zao)型机(ji)相适应,才能(neng)最大(da)限度的(de)发挥造(zao)(zao)(zao)型机(ji)的(de)效能(neng)。

       每(mei)种机型都有自(zi)已的(de)优(you)缺点,客(ke)户(hu)应根据自(zi)已的(de)产品(pin)特(te)点,选择适(shi)合自(zi)已产品(pin)的(de)造型线,铸(zhu)件(jian)的(de)品种(zhong)多少、材质种(zhong)类、零件(jian)大(da)小、重量(liang)(liang)、壁厚、冷(leng)却时间、批量(liang)(liang)大(da)小、日产(chan)量(liang)(liang)、每(mei)模砂(sha)芯(xin)数(shu)量(liang)(liang)、砂(sha)芯(xin)复杂程度(du)、熔(rong)炼(lian)方式、浇(jiao)铸方式、砂(sha)处理质量(liang)(liang)、供砂(sha)速度(du)、模具情(qing)况、人员素质结(jie)构、维修、保养维护能(neng)(neng)力(li)、人员的(de)学习接受(shou)能(neng)(neng)力(li)、责任心、资(zi)金状(zhuang)况、投资(zi)规模、供应商所处地区(qu)、供应商的(de)设(she)计生产(chan)加(jia)工、服务(wu)能(neng)(neng)力(li)等(deng)等(deng)来综合考虑选择(ze)造型设(she)备。
