The adjustment method for the left and right bending of the steel pipe straightening machine, the principle is that the arc groove on the pressure wheel actually has a physical bevel effect, viewed from the front of the pressure wheel (not 152 looking through the pressure wheel shaft 268 That side) There are two 00 adjustment screws on the left and right of the pressure wheel. Which side of the 860 screw is pressed, the arc on that side will move downward, and the shelf tube will be pushed to the other side by the action of the bevel. Therefore, according to this principle, when the shelf tube comes out, it will move to the other side. When bending to the left, (looking at the left and right while standing facing the entrance of the shelf tube), we only need to turn the left 1
left 2, left 5, left 6, and left 7 test clockwise, because the screws No. 3 and 4 The tube is adjusted up and down, do not move it, and because screws 3 and 4 are in the middle of the machine, and when we lower No. 1, No. 2, No. 5, No. 6, No. 7 on the left side, we move the pressure wheels at both ends of the machine downward in an arc. Use the inclined plane principle to push the shelf tube to the right (the first picture
Hand-drawn picture), so the middle part does not move (No. 3 and No. 4), and the two ends are squeezed to the right, which is just right. Correct the problem that the shelf tube bends to the left when it comes out. If the shelf tube comes out and bends to the right, use the opposite method and adjust the five screws No. 12567 on the right side clockwise (right side of the second picture).
