模锻件图
模锻件图
Die forgings
模锻件图是锻件图的一种,也有人简称为锻件图或毛坯图,除“锻件图”条中各项要求外,模锻件图绘制时由于本身特点还必须考虑:分模线位置;选定模锻斜度、决定冲孔连皮的型式;锻造工艺对锻件纤维方向的影响;机械性能试棒的位置;印记、钢号位置等。质量合格的锻件还必须具备下列要求:按锻造工艺规程锻制的锻件,其全部尺寸均应符合模锻件图上尺寸的要求,同时,必须满足模锻件图上所规定的技术条件要求,如热处理硬度、错移量大小、毛边痕大小、弯曲度、壁厚差、表面缺陷、除掉氧化皮及机械性能要求等  。
Die forging drawing is a kind of forging drawing, and it is also referred to as forging drawing or blank drawing for short. In addition to the requirements in the "forging drawing" bar, the drawing of die forging must also be considered for its own characteristics: the position of die dividing line, the selection of die forging slope, the determination of piercing and connecting pattern, the influence of forging process on the direction of forging fiber; The position of the test bar, the location of the mark, the steel number, etc. Qualified forgings must also meet the following requirements: the forgings forged according to the forging process specifications, the full size of the forgings should meet the requirements of the die forging drawing dimensions, at the same time, must meet the requirements of the die forging drawing as specified in the technical conditions, such as heat treatment hardness, displacement size, the size of the brim mark, bending, wall thickness difference. Surface defects, removal of oxide scale and mechanical properties.
曲轴锻压机用模锻件图:曲轴锻压机用模锻件图与制订锤上模锻件图的规则基本相同,但有以下三条特殊考虑因素:(1)锻压机具有顶杆装置,就可以立着锻造带长杆的锻件(即杆的轴线与滑块运动方向一致),以减少在分模面上锻件的周界,并减少毛边金属的消耗;(2)锻压机上模锻的锻件,它的余量的平均尺寸比锤上小30~50%,具体数字可查有关手册确定;(3)如靠手钳将锻件从模槽中取出的话,模锻斜度与锤上锻件一样确定,当采用顶杆将锻件顶出时,模锻斜度可显著地减小,但也不能完全没有,否则顶杆受负荷过大
Die forging drawings for crankshaft forging press: Die forging drawings for crankshaft forging press are basically the same as those for hammer forging drawings, but there are three special considerations: (1) Forging press with a plunger can be erected to forge forgings with long bars (i.e. the axis of the rod is in line with the direction of slider movement) to reduce die splitting. The margin of the forgings on the surface is reduced and the consumption of the rough edge metal is reduced; (2) The average size of the forgings on the forging press is 30-50% smaller than that on the hammer, and the specific figures can be determined according to the relevant manuals; (3) If the forgings are removed from the die groove by hand tongs, the die forging inclination is determined as well as the forgings on the hammer, when the plunger is used. When the forging is ejected, the die forging inclination can be significantly reduced, but it can not be completely eliminated, otherwise the ejector bar will be overloaded.
