最近才发展的靜液挤压,是采用高压液体(图1b)代替通常的柱塞(图1a)将坯料挤压出模子的一种加工方法。虽然某些工艺是在较高的温度下做的,但一般靜液挤压还是在室温下进行。 靜液挤压的特点 靜液挤压的主要优缺点可从图1b中看出,包括下列几点: 1.在模子入口处连续供应高压液体(通常还混有润滑液),保证在坯料和模子接触
The recent development of hydrostatic extrusion is a machining method of extruding a billet out of a mold using a high pressure liquid (Figure 1b) instead of a conventional plunger (Figure 1a). Although some processes are done at higher temperatures, hydrostatic extrusion is generally carried out at room temperature. The main advantages and disadvantages of hydrostatic extrusion The main advantages and disadvantages of hydrostatic extrusion can be seen in Figure 1b, including the following points: 1. Continued supply of high pressure liquid at the entrance to the mold (usually also mixed with lubricating fluid) to ensure that the blank and Mold contact
