山東鋁合金壓鑄的生產工藝流程是怎么樣的

  鋁合金鑄件被廣泛應用在航空航天、機械、車輛等諸多行業中,對于它的致密性的要求也越來越高。從事生產的鋁合金壓鑄廠家,也在嘗試用多種方式提高致密性,包括真空壓鑄法。
  Aluminum alloy castings are widely used in aerospace, machinery, vehicles and many other industries, and their compactness requirements are getting higher and higher. Aluminum alloy die casting manufacturers are also trying to improve compactness in a variety of ways, including vacuum die casting.
  真空壓鑄法包括兩種方式,一是激冷排氣槽法,二是真空閥法。激冷排氣槽法使用的是厚度薄、寬大的搓板狀排氣槽,外部連接真空泵或真空罐。鋁合金壓鑄廠家準備好的合金液流入排氣槽后迅速凝固并堵住氣道,防止合金液進入真空管道。使用這種方式,結構簡單,成本低,應用廣泛,但型腔中的真空度波動大,穩定性比較差。
  Vacuum die casting method includes two ways, one is chilled exhaust tank method, the other is vacuum valve method. The chilled exhaust chute method uses a thin and wide rubbery exhaust chute, which is connected with a vacuum pump or a vacuum tank. Aluminum alloy liquid prepared by die-casting manufacturer flows into the exhaust slot and solidifies rapidly and blockages the airway to prevent alloy liquid from entering the vacuum pipeline. With this method, the structure is simple, the cost is low and the application is extensive, but the vacuum in the cavity fluctuates greatly and the stability is poor.
  真空閥法使用的是專用的遮斷網,將其安裝在模具的分型面上,利用冶金業流動的慣性關閉閥芯。山東鋁合金壓鑄廠家使用的真空閥法真空度高,穩定,排氣道設置靈活,也可以將真空閥安裝在機器壓室上。
  The vacuum valve method uses a special blocking net, which is mounted on the parting surface of the die and utilizes the inertial closing spool flowing in the metallurgical industry. The vacuum valve method used by Shandong Aluminum Alloy Die Casting Factory has high vacuum degree, stability, flexible exhaust duct setting, and can also be installed on the machine pressure chamber.
  鋁合金鑄件是精度高、尺寸準確的壓鑄件,用來制作汽車配件是不錯的選擇。廠家下面就來為您簡單介紹一下鋁合金壓鑄件的生產工藝流程,讓您對它有更加深入的了解。
  Aluminum alloy castings are die castings with high precision and accurate size. It is a good choice to make automobile parts. The manufacturer will give you a brief introduction to the production process of aluminium alloy die castings, so that you can have a deeper understanding of it.
  總體來說,制作鋁合金鑄件要經過四把火,分別是退火、正火、淬火和回火,在壓鑄過程中,淬火和回火十分重要,都不能缺少。鋁合金壓鑄過程中,工人先將金屬液通過低速或高速填充到模具的型腔內,模具內有活動的型腔面,會隨著金屬液的冷卻而加壓鍛造。在這個過程中,能夠消除毛坯的縮孔縮松缺陷,也可以使毛坯的內部組織達到鍛態的破碎晶粒。
  Generally speaking, the production of aluminium alloy castings needs four fires, namely annealing, normalizing, quenching and tempering. In the process of die casting, quenching and tempering are very important and can not be lacked. In the process of aluminium alloy die casting, the worker first fills the metal liquid into the cavity of the die through low or high speed. The active cavity surface in the die will be forged under pressure with the cooling of the metal liquid. In this process, the shrinkage defect of the blank can be eliminated, and the inner structure of the blank can reach the broken grain as forged.

  如果您對山東鋁合金壓鑄生產工藝流程還不夠了解,那我們就通過一個簡單的圖解來了解一下:壓鑄機調試——壓鑄模安裝——涂料配制——模具預熱、涂料——調整脫模劑量和噴射位置——合型(合模)——澆注壓射——保壓——開模(取出鑄件)。
  If you don't know enough about the production process of Shandong aluminium alloy die casting, we will understand it through a simple diagram: die casting machine debugging - die casting die installation - coating preparation - die preheating, coating - adjusting the release dose and injection position - closing (closing) - casting injection - holding - opening (taking out casting).
