依出料速度之需要，自动调控送料时间，配合冲床的冲压速度。

The feeding speed can be adjusted to synchronize with the press automatically.

另外，拉深温度的降低，冲压速度的增加，摩擦系数的增大都会使拉深时的最大冲程力增大。

In addition, the decline of the temperature, the raise of the drawing velocity, the raise of the friction coefficient all could lead to the increase of the maximum stroke force.

因为这台压机的冲压速度达到1，100 rpm 如果用来冲铝件的话，可能会产生皱褶，所以要把速度降至700 rpm。

With press speeds of up to 1, 100 rpm, the aluminum going through the line would have been shredded, at best. So things had to slow down to about 700 rpm.
