山东铝合金压铸的生产工艺流程是怎么样的

来源:    发布时间:2019-04-12 14:13:44    点击:

  铝合金铸件被广泛应用在航空航天、机械、车辆等诸多行业中,对于它的致密性的要求也越来越高。从事生产的铝合金压铸厂家,也在尝试用多种方式提高致密性,包括真空压铸法。
  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.
  真空压铸法包括两种方式,一是激冷排气槽法,二是真空阀法。激冷排气槽法使用的是厚度薄、宽大的搓板状排气槽,外部连接真空泵或真空罐。铝合金压铸厂家准备好的合金液流入排气槽后迅速凝固并堵住气道,防止合金液进入真空管道。使用这种方式,结构简单,成本低,应用广泛,但型腔中的真空度波动大,稳定性比较差。
  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.
  真空阀法使用的是专用的遮断网,将其安装在模具的分型面上,利用冶金业流动的惯性关闭阀芯。山东铝合金压铸厂家使用的真空阀法真空度高,稳定,排气道设置灵活,也可以将真空阀安装在机器压室上。
  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.
  铝合金铸件是精度高、尺寸准确的压铸件,用来制作汽车配件是不错的选择。厂家下面就来为您简单介绍一下铝合金压铸件的生产工艺流程,让您对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.
  总体来说,制作铝合金铸件要经过四把火,分别是退火、正火、淬火和回火,在压铸过程中,淬火和回火十分重要,都不能缺少。铝合金压铸过程中,工人先将金属液通过低速或高速填充到模具的型腔内,模具内有活动的型腔面,会随着金属液的冷却而加压锻造。在这个过程中,能够消除毛坯的缩孔缩松缺陷,也可以使毛坯的内部组织达到锻态的破碎晶粒。
  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.

  如果您对山东铝合金压铸生产工艺流程还不够了解,那我们就通过一个简单的图解来了解一下:压铸机调试——压铸模安装——涂料配制——模具预热、涂料——调整脱模剂量和喷射位置——合型(合模)——浇注压射——保压——开模(取出铸件)。
  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).
