今天带大家走进车间,实拍 W11S 上辊万能式三辊卷板机完整卷圆作业,直观了解罐体、圆筒工件从平板到成型的整套工艺。作为压力容器、钢结构行业主流的板材成型设备,上辊万能式卷板机区别于普通对称三辊卷板机,核心优势就在于上辊拥有液压垂直升降 + 机械水平移位两组调节动作,依靠独特的非对称辊位结构,实现一次装夹、无需工件掉头,就能完成板材两端预弯、往复卷圆、成品校圆,选配卷锥装置后还可加工锥形筒件,大幅简化加工工序,减少配套设备投入。


实拍现场,操作人员先对板材进行检查、划线定位,将平整钢板平稳送入上下辊之间,对齐基准线。普通三辊卷板机最让人头疼的就是两端长直边问题,后期还要单独上压力机压头预弯,费时费力,而这台上辊万能卷板机直接通过上辊水平偏移,让上辊偏离两下辊中心,形成非对称辊压点位,先对板材端头进行预弯加工。这个步骤会把板材两端提前压出和成品一致的圆弧,最大限度缩短剩余直边,预弯完成后,再把上辊复位到合适位置,液压系统驱动上辊垂直下压设定成型压力,两台下辊由减速机同步驱动旋转,依靠辊面摩擦力带动板材来回往复送料滚压。


随着一次次滚卷,平板在三点弯曲原理作用下逐步发生塑性变形,平缓的板面慢慢收拢成连续圆弧。操作工按照工艺要求逐步增加下压量,分次成型,不会一次性强行压下,避免板材打滑、表面压伤、圆弧塌边。每滚压几圈就停下观察弧度,对照样板测量曲率,不断微调上辊压力与位置,保证整根筒身弧度均匀,圆度误差可控。等到板材两端对接闭合,初步形成圆筒之后,工序还没有结束,工件可以再次送入辊缝进行整体校圆,修正卷制过程中产生的椭圆、弧度不均等缺陷,最终得到符合图纸要求的圆筒工件。


本机辊芯选用 42CrMo 优质合金钢,经过调质、淬火、精磨处理,辊面硬度高、耐磨抗形变,厚板加工时抗挠度表现稳定,不容易出现中间鼓弧、两头偏小的问题;机身采用整体钢板焊接结构,经过时效去应力处理,刚性扎实,长时间连续作业不易变形。设备有常规液压数显款和全自动数控款可选,数控版本搭载 PLC 触摸屏、位移传感器,上辊垂直、水平位移实时数字显示,加工参数可以存储调用,同一规格工件重复生产时一致性更好,降低对老师傅操作经验的依赖,新手也可以快速上手。


材料适配范围广,低碳碳钢、不锈钢板、铝板、低合金钢板都可以稳定卷制,薄板成型顺滑,厚板承载力充足。成品工件广泛用于化工压力容器、锅炉筒体、环保除尘罐体、管道、塔筒、工程机械弧形构件、粮仓筒仓等。对比四辊卷板机,上辊万能机型采购成本更友好,维护简单,非常适合中小型钣金、钢结构、罐体加工厂;对比普通对称三辊,省去掉头、二次预弯工装,单件加工效率明显提升,适合批量订单生产。


本次实拍全程为车间真实生产场景,没有特效修饰,可以直观看到板材进给、预弯、卷圆、校圆的每一步变化。南通苏玺机械 W11S 上辊万能式卷板机支持非标定制,可根据客户板厚、板宽、最小卷圆直径定制机型,从小型薄板款到大吨位厚板重型机型均可生产,同时可以选配卷锥工装、下辊托辊、安全防护装置等配件,提供试卷、现场调试、技术培训服务。有卷圆、卷锥加工需求的客户,欢迎索取试卷视频,来厂实地看机试板。
