山東鋁合金壓鑄表面加工有哪些要求

  說到鋁合金鑄件,很多朋友想到的都是它的尺寸精準,金屬利用率高等一系列優點。但對于廠家來說,成品鋁合金壓鑄件需要達到相應的表面質量要求,這樣才能上市銷售。
  Speaking of aluminium alloy castings, many friends think of a series of advantages, such as its precise size and high metal utilization rate. However, for manufacturers, finished aluminum alloy die castings need to meet the corresponding surface quality requirements, so as to be marketed.
  鋁合金鑄件是金屬利用率高、表面光滑平整、尺寸精準的加工件,行業對鋁合金壓鑄件加工面和不加工面表面質量都有嚴格要求,我們今天著重介紹下加工面質量要求。
  Aluminum alloy castings are processed with high metal utilization rate, smooth surface and precise size. The industry has strict requirements on the surface quality of aluminium alloy die castings and non-processed surface. Today, we focus on the quality requirements of the lower processed surface.
  鋁合金鑄件允許存在表面缺陷,它的質量級別分為1級、2級和3級,這三級的缺陷面積分別不能超過總面積的5%、25%和40%。要特別說明的是,在不影響裝配和使用的情況下,鋁合金壓鑄件網狀毛刺和痕跡的高度不能超過0.2㎜;鑄件受到壓鑄模鑲塊和分型面影響會產生表面高低不平的偏差不能超過相關的公差尺寸;推桿痕跡表面凹陷或凸起鑄件表面的深度為±0.2㎜。
  Surface defects are allowed in aluminium alloy castings, and their quality levels are classified into 1, 2 and 3 grades. The defect areas of these three grades can not exceed 5%, 25% and 40% of the total area, respectively. In particular, without affecting assembly and use, the height of mesh burrs and marks in aluminium alloy die castings should not exceed 0.2; the surface roughness deviation caused by the influence of die casting die inserts and parting surfaces should not exceed the relevant tolerance size; and the depth of the surface depression or protrusion of push rod marks should be (+0.2).
  壓鑄件表面不能出現明顯的凹陷,眼睛看過去要求挫痕均勻、一致。不管是否經銼加工,表面角度都不能超過10°。鋁合金壓鑄件成型后,遇到變形情況應調整,調整后的鑄件表面不能有明顯擊打痕跡,調整部分的平面度在0.2㎜左右。

  The surface of die castings can not appear obvious depression, the eyes look at the past requires even and consistent contusion. The surface angle should not exceed 10 degrees regardless of whether it is filed or not. Aluminum alloy die castings should be adjusted when they are deformed after forming. The surface of the adjusted castings can not have obvious striking marks. The flatness of the adjusted parts is about 0.2_.
  行業中規定,鋁合金鑄件不加工面表面允許存在高度小于0.2㎜的網狀毛刺和痕跡,前提是不影響使用和裝配。鋁合金壓鑄件在加工過程中,可能會受到模具組合鑲拼和分型面影響,表面平面度誤差需保證在該尺寸的極限偏差范圍內。穿孔頂端的隔皮厚度不能超過相關數值的規定。
  It is stipulated in the industry that mesh burrs and marks with height less than 0.2_are allowed on the surface of non-machined surface of aluminium alloy castings, provided that they do not affect the use and assembly. Aluminum alloy die castings may be affected by die assembly and parting surface during processing. Surface flatness error should be guaranteed within the limit deviation of this dimension. The diaphragm thickness at the top of the perforation should not exceed the relevant values.
