数控转塔冲床能够应用在哪些领域?其发展前景怎么样?

数控转塔冲(chong)(chong)床以其高精度、高效(xiao)率和(he)快速性应用(yong)于(yu)许多(duo)钣金制品行业(ye),广泛应用(yong)于(yu)电气(qi)柜、电气(qi)、电子(zi)设(she)备(bei)(bei)、电力设(she)备(bei)(bei)、厨房(fang)设(she)备(bei)(bei)、铁路设(she)备(bei)(bei)等行业(ye)。冲(chong)(chong)压(ya)动力系(xi)统作为数控转塔冲(chong)(chong)床的(de)关(guan)键部件,经过(guo)多(duo)年(nian)的(de)发(fa)展和(he)技(ji)术(shu)创新,逐渐实现了低噪(zao)音(yin)、环(huan)保、节能、高效(xiao)率的(de)目标(biao)。下面简述了数控转塔冲(chong)(chong)床冲(chong)(chong)压(ya)技(ji)术(shu)、加工技(ji)术(shu)的(de)发(fa)展及工作效(xiao)率的(de)优化。
根据(ju)冲压系统结构,数控(kong)转塔冲床可分为三(san)种(zhong)类型:
一、机(ji)械(xie)驱动(dong)数控(kong)转(zhuan)塔(ta)(ta)冲(chong)(chong)床(chuang)。早期由机(ji)械(xie)驱动(dong)的数控(kong)转(zhuan)塔(ta)(ta)冲(chong)(chong)床(chuang),利用自身重量(liang)产生的惯(guan)性(xing)力下压(ya)(ya),利用电机(ji)带动(dong)飞轮(lun)高速(su)旋转(zhuan)下压(ya)(ya),并通过(guo)离(li)合(he)装置控(kong)制运动(dong)过(guo)程中的动(dong)力传(chuan)(chuan)(chuan)递。这种类型(xing)的传(chuan)(chuan)(chuan)动(dong)结(jie)构制造(zao)容易(yi),原理简单,但缺(que)点(dian)也(ye)很明显(xian):传(chuan)(chuan)(chuan)动(dong)结(jie)构的飞轮(lun)旋转(zhuan)一整(zheng)圈,然后冲(chong)(chong)头完(wan)成(cheng)一次冲(chong)(chong)压(ya)(ya),每分钟冲(chong)(chong)压(ya)(ya)次数不(bu)到300次;工作噪(zao)音大,由于(yu)速(su)度不(bu)可调,接触板(ban)材时(shi)速(su)度较(jiao)快(kuai),冲(chong)(chong)击噪(zao)音较(jiao)大;工作下止点(dian)无法调整(zheng),需要调整(zheng)模(mo)具高度,以(yi)满足(zu)不(bu)同高度的成(cheng)型(xing)和冲(chong)(chong)压(ya)(ya)要求。
二、液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)驱(qu)动数控(kong)转塔冲床(chuang)。随着市场需求的(de)(de)(de)不(bu)断(duan)扩大和(he)液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)技术成(cheng)熟度(du)(du)和(he)稳定性(xing)的(de)(de)(de)提高(gao),液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)系(xi)统应(ying)用(yong)于数控(kong)转塔冲床(chuang),液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)冲床(chuang)系(xi)统和(he)控(kong)制(zhi)(zhi)器由(you)国内公司生产。这(zhei)种(zhong)液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)冲床(chuang)系(xi)统通过(guo)电磁阀控(kong)制(zhi)(zhi)液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)缸上下(xia)运行,完成(cheng)各种(zhong)复杂的(de)(de)(de)成(cheng)形工(gong)作,如滚筋、凸包、桥梁、百叶窗(chuang)、滚剪、滚切等。与(yu)机械冲床(chuang)相比有质的(de)(de)(de)提高(gao)。但液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)车型也有一些因(yin)自(zi)身特点(dian)难以(yi)解决的(de)(de)(de)问(wen)题,主要(yao)(yao)包括以(yi)下(xia)几(ji)点(dian):液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)油是一种(zhong)消(xiao)耗(hao)品,长期(qi)使用(yong)会因(yin)液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)元(yuan)件的(de)(de)(de)磨损和(he)冲击而导致油品变质,因(yin)此一般(ban)需要(yao)(yao)每2年更换(huan)一次液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)油,以(yi)保(bao)证系(xi)统长期(qi)稳定运行;环境温(wen)度(du)(du)高(gao),温(wen)度(du)(du)过(guo)低时需要(yao)(yao)提前启动并预热油泵,使其只有在温(wen)度(du)(du)达(da)到5以(yi)上才能正常(chang)工(gong)作,而温(wen)度(du)(du)过(guo)高(gao)时,油液(ye)(ye)(ye)粘度(du)(du)变稀(xi),导致液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)控(kong)制(zhi)(zhi)元(yuan)件位置控(kong)制(zhi)(zhi)精度(du)(du)偏差(cha)较大;液(ye)(ye)(ye)压(ya)(ya)(ya)(ya)冲床(chuang)油泵能耗(hao)高(gao),每小时综合(he)电耗(hao)达(da)10kW以(yi)上。
三、采用机(ji)(ji)械(xie)伺(si)(si)服冲(chong)床传(chuan)(chuan)动(dong)结构的(de)(de)数控转塔(ta)冲(chong)床。传(chuan)(chuan)统的(de)(de)机(ji)(ji)械(xie)液压转塔(ta)冲(chong)床存(cun)在一定(ding)的(de)(de)缺(que)陷,各主(zhu)机(ji)(ji)厂商(shang)也在不断寻找更节能高效的(de)(de)解决方案。由扭矩(ju)伺(si)(si)服电机(ji)(ji)驱(qu)动(dong)的(de)(de)机(ji)(ji)械(xie)伺(si)(si)服数控转塔(ta)冲(chong)床逐渐推(tui)向(xiang)市场(chang),并迅速占据传(chuan)(chuan)统液压转塔(ta)冲(chong)床的(de)(de)市场(chang)份额。
随着数(shu)控转塔冲床(chuang)加工(gong)技术的(de)(de)发(fa)展(zhan),满足了钣(ban)(ban)金加工(gong)中复杂成形和高精度工(gong)件加工(gong)的(de)(de)要(yao)求,提(ti)高了钣(ban)(ban)金加工(gong)生产率,保证了钣(ban)(ban)金零件的(de)(de)质量和产量,也降低了工(gong)人的(de)(de)劳动(dong)强(qiang)度和生产成本(ben)。随着机(ji)床(chuang)智能化、自动(dong)化的(de)(de)快速发(fa)展(zhan),钣(ban)(ban)金加工(gong)行业(ye)也呈现(xian)出(chu)加工(gong)方(fang)式多样(yang)化、机(ji)床(chuang)操作智能化、自动(dong)化的(de)(de)发(fa)展(zhan)趋势。
