背景技术 Background technique
闭塞锻造是一种当代先进的精密锻造工艺技术。闭塞锻造又称为闭塞挤压，其原理是将两个或几个可分凹模用足够大的合模力闭合成一个封闭的模腔，金属毛坯在一个或多个冲头的单向或对向运动下，通过挤压充满模腔，从而得到一个与模腔形状和尺寸完全相同的精锻件。但闭塞模架能容纳的弹性元件的空间非常有限，因此在锻造过程中有所缺陷，且一般的液压装置在锻造前，无法将空气更好的排出，从而影响锻造效果。 Block forging is a contemporary advanced precision forging technology. Block forging is also called block extrusion. Its principle is to close two or more separable dies with a large enough clamping force to form a closed cavity. Under the opposite movement, the die cavity is filled by extrusion, so as to obtain a precision forging with the same shape and size as the die cavity. However, the space of the elastic elements that can be accommodated by the closed formwork is very limited, so there are defects in the forging process, and the general hydraulic device cannot discharge the air better before forging, thus affecting the forging effect.
