Description

六边形方板锻造方法
技术领域
本发明涉及锻造技术领域,具体地说,是一种用于六边形方板的锻造方法。
背景技术
现有技术中,六边形方板的常规锻造方案如图1所示,通常采用锻造圆形锻件,再按图纸尺寸进行机加工方式加工成型。
上述常规锻造方案,均存在加工余量大,加工成本高的问题,需要厚度加工到位后再划线铣加工成六边形,机加工费用高,加工周期长,在成本控制和交货期上存在严重不足。
急需针对该类产品,设计出一套更加有效的锻造工艺。
发明内容
本发明要解决的技术问题:首先,降低成本,提高市场竞争力;其次,提高生产效率。
为了解决上述技术问题,本发明提供一种六边形方板锻造方法,包括以下步骤:
S1:加热坯料至1220℃,保温3.5小时,一次拔长至420mm×420mm方,850mm长;
S2:一次镦粗至600mm×600mm,高400mm;
S3:二次拔长至420mm×420mm方,845mm长;
S4:二次镦粗至350mm高,外径730mm;
S5:锻造出坯后按角度进行旋转进行锻造,精整成形六边形方板。
优选的,所述的S1中,下料重量1180KG、钢锭头部尺寸550mm/尾部尺寸490mm,长度556mm方锭。
优选的,所述的S5中,具体的锻造方法包括以下步骤:
A)先出坯成饼型锻件;
B)操作机夹紧锻件厚度方向,上下砧重压出两边;
C)压出两条边后旋转至第一位置点和第二位置点在同一直线上,再上下砧重压出两边;
D)压出四条边后旋转至第三位置点和第四位置点在同一直线上,再上下砧重压出两边成型。
本发明优点在于:
本发明的六边形锻造方法目的是锻造出六边形形状,余量尽可能的接近成品尺寸,一方面降低了原材料下料重量,降低了成本,提高市场竞争力;另一方面减少了加工余量,提高了生产效率,节约了加工周期。
附图说明
图1是现有技术的出坯示意图,锻造成饼型;
图2是本发明的六边形方板锻造方法的加工成型方法示意图;
图3是六边形方板的示意图;
图4是六边形方板锻件图。
附图中涉及的附图标记和组成部分如下所示:
1-第一位置点 2-第二位置点
3-第三位置点 4-第四位置点
具体实施方式
下面结合实施例对本发明提供的具体实施方式作详细说明。
实施例1
针对图4的锻件图,下料:1180kg;
该批生产锻件钢锭头部尺寸550mm/尾部尺寸490mm,长度556mm方锭。
具体包括以下步骤:
S1:加热坯料至1220℃,保温3.5小时,一次拔长至420mm×420mm方,850mm长;
S2:一次镦粗至600mm×600mm,高400mm;
S3:二次拔长至420mm×420mm方,845mm长;
S4:二次镦粗至350mm高,外径730mm;
S5:锻造出坯后按角度进行旋转进行锻造,精整成形六边形方板(如图3所示)。
如图2所示,所述的S5中,具体的锻造方法包括以下步骤:
A)先出坯成饼型锻件;
B)操作机夹紧锻件厚度方向,上下砧重压出两边;
C)如图2所示,压出两条边后旋转至第一位置点1和第二位置点2在同一直线上,再上下砧重压出两边;
D)如图2所示,压出四条边后旋转至第三位置点3和第四位置点4在同一直线上,再上下砧重压出两边成型。
原有工艺锻造成饼型锻件(图1),该规格下料重量为1370KG,通过本发明锻造工艺锻造成六边形方块,下料重量1180KG,降低了原材料成本,减少了加工周期。如图2、图3所示,利用该锻造方法,解决了图1锻件产品余量较大,机加工时间较长等情况。节约了公司成本,提高了生产效率。
以上已对本发明创造的较佳实施例进行了具体说明,但本发明创造并不限于所述实施例,熟悉本领域的技术人员在不违背本发明创造精神的前提下还可做出种种的等同的变型或替换,这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
