筒形件卷制后需要整圆。原来我们是用卷床加大锤的方法,劳动强度大。现在用卷床加垫板的方法,就能将筒体整圆,既提高了工效,又减轻了劳动强度。现将整圆方法介绍如下。一、各种变形的整圆方法1.全长呈内桃形或出现直段(见图1)。在变形区,从接触开始转动,由欠压-常压-过压,左右反复转动几次,即可基本消除桃形或直段,再配 Cylindrical shape after the need for a full circle. The original method we used to increase the weight of the hammer bed, labor-intensive. Now with the method of volume bed pad, you can round the cylinder, not only improve the work efficiency, but also reduce the labor intensity. Now the whole circle method is as follows. First, a variety of deformation of the round method 1. The length of the peach-shaped or appear straight segment (see Figure 1). In the deformation zone, from the start of contact rotation, from undervoltage - atmospheric pressure - over-pressure, left and right repeatedly rotated several times, you can basically eliminate the peach-shaped or straight section, and then with
