The deformation of Wuxi special-shaped pipe is divided into angle deformation and bending deformation, and their respective correction methods are also different. If the actual operation is unreasonable, it will cause counter actual effect. It is very important to correct the actual operation sequence of Wuxi special-shaped pipe. Generally, it is necessary to correct the deformation of the visual angle first and use 90 ° The angular punch and die shell shall be corrected according to the pressing and jacking method of mechanical equipment. However, if the angle of view exceeds this standard, one side of Wuxi special-shaped pipe must be erected on the plan, and then the other limb edge shall be knocked with a hammer immediately until the required angle of view is achieved. If the angle of view of raw materials is smaller and smaller, then it is necessary to put its inner angle vertically on a plane diagram, and use a suitable angle of view hammer or hammer on the inner angle, and strike with a hammer, the actual effect of correction will also appear. After the correction of the angle deformation, the bending deformation of Wuxi special-shaped pipe is gradually corrected. The angle iron is corrected with a hammer, the cold drawn angle iron is put on the straightening frame, and the vertical side surface and angle rib part surface of Wuxi special-shaped pipe are hit with a hammer, so as to achieve the goal of correction.

1. Correction of visual angle deformation of Wuxi special-shaped pipe. It can be made into 90 ° Angular punch and die shell are corrected by pressing and jacking with mechanical equipment; A small amount of deformation can be carried out together with straightening. When its perspective is more than 90 ° When the position of one limb is on the plan, immediately knock the other limb with a hammer to make the angle of view 90 ° Time cut-off; Its perspective is less than 90 ° When the internal angle is vertically placed on a plan, the appropriate angle hammer or hammer is placed on the inner corner, and the hammer is knocked with a hammer to expand the angle of view to 90 °。

2. Correction of bending deformation of Wuxi special-shaped pipe. Correct the angle iron with a hammer and put the cold drawn angle iron on the straightening frame. According to the length of the Wuxi special-shaped pipe, one or two people hold the top of the angle iron tightly, and the other person uses the hammer to hit the vertical side surface and angle rib part surface of the Wuxi special-shaped pipe, which is accurate and stable. According to the bending and rotation transformation of each surface of Wuxi special-shaped pipe and the position where the hammer stands, the handle of the hammer should be slightly raised or lowered when the hammer strikes each surface of the pipe. The high and low intersection angle between hammer surface and Wuxi special-shaped pipe surface is about 3 °- ten °。 In this way, the hammer has push-pull interaction force on Wuxi special-shaped pipe, so as to keep the center of gravity of cold-drawn angle iron bearing force balanced, so that it is not easy to overturn the cold-drawn angle iron and prevent hand shaking.
