塑料模具的加工速度有什么要求

来源:    发布时间:2019-05-15 13:45:33    点击:

  为什么加工速度在注塑成型中非常重要,因为它不仅关系到零件的加工周期,还决定着加工的经济成本。我们常说电火花加工速度(EDM machining speed)是指在一定脉冲参数下,在同一单位时间内被蚀刻掉的一定质量和体积的工件,这可以分别用体积加工速度或质量加工速度来表示。
  Why is the processing speed very important in injection molding, because it not only relates to the processing cycle of parts, but also determines the economic cost of processing. We often say that EDM machining speed refers to a certain mass and volume of workpiece etched in the same unit time under certain pulse parameters, which can be expressed by volume processing speed or mass processing speed respectively.
  在表面粗糙度相同的模具钢上,电极丢失时相对电脉冲产生的比较大加工速度是衡量电脉冲加工和机床加工性能的重要指标。通常状况下的加工厂得出的是较大挤压成型交流电,在比较好挤压成型情况下能够超过的比较大的挤压成型速率。因而在人们具体挤压成型时,因为被零件加工规格与样子的千姿百态,加工条件和排屑条件不同于理想条件。即使在加工进行粗加工时,加工速度通常也远低于机床的比较大加工速度指标。
  On die steels with the same surface roughness, the maximum processing speed of relative electric pulse when electrodes are lost is an important index to measure the processing performance of electric pulse machining and machine tools. Usually, the processing plants get a larger AC extrusion forming, which can exceed the maximum extrusion forming rate under the best extrusion forming conditions. Therefore, in extrusion moulding, the processing conditions and chip removal conditions are different from the ideal conditions because of the various processing specifications and shapes of the parts. Even when roughing is carried out in a machining center, the processing speed is usually much lower than the maximum processing speed of a machine tool.

  每一注塑加工脉宽蓄电池充电的当时都是在钢件表层留有1个细微的凹痕,凹痕的尺寸、蚀除材质的几个与脉宽动能相似性正相关关联,即脉宽动能越大,传送给钢件上的卡路里就会越大,被蚀除的材质也越大。从方法论上讲得话激光焊成型挤压成型速率正比于单独脉宽动能和蓄电池充电頻率,但在具体挤压成型中,单独脉宽的功效没有独立反映的,只是好几个脉宽相互功效的結果,脉冲电源是接连不断地以脉宽情况向挤压成型空隙运输动能,其流程就繁杂得多,挤压成型速率是和脉宽蓄电池充电時间、脉宽间距、脉宽蓄电池充电交流电、脉宽波型、挤压成型成员变量特性、电极材料、铣面标准等相关的多样化涵数。
  At the time of charging for each injection-moulded pulse-width battery, there is a tiny dent on the surface of the steel. The size of the dent and the material of the etched material are positively correlated with the similarity of the pulse-width kinetic energy. That is, the larger the pulse-width kinetic energy is, the larger the calories transmitted to the steel parts will be, and the larger the material of the etched part will be. From the methodological point of view, the extrusion forming rate of laser welding is proportional to the pulse width kinetic energy and battery charging frequency, but in the specific extrusion forming, the effect of the pulse width alone is not independently reflected, but the result of the mutual effect of several pulse widths. The pulse power supply is continuously transporting kinetic energy to the extrusion forming gap with the pulse width, and its process is much more complicated. Type I rate is a variety of connotations related to charging time, pulse width spacing, AC charging, pulse width wave type, variable characteristics of extrusion forming members, electrode materials, milling surface standards and so on.
  挤压成型速率在磨具注塑加工中非常关键。由于它是塑胶产品出样的必要条件。假如顾客规定品质好一点的基本上再提早交样得话,挤压成型時间和速率是比较关键的。
  Extrusion forming rate is very important in abrasive injection processing. Because it is a necessary condition for plastic products to be produced. If the customer stipulates that the quality is better and the sample is delivered earlier, the extrusion forming time and rate are the most critical.
