How To Avoid Wrinkling When Bending The Pipe?
Large-diameter elbows are often used in the construction of long-distance pipelines. In the process of use, it is necessary to effectively test the angle of the elbows required according to the actual direction of the pipelines, and effectively use its vertical angle during the production process. The hydraulic pipe bending machine is made on site.
In the process of research and development and experiments, the quality of the product needs to be effectively guaranteed, so that the common defects of the product can be effectively analyzed and controlled. Completed.
Put the steel pipe on the pipe bending equipment, so that the equipment will effectively apply the bending moment to the steel pipe, which will directly cause the appropriate amount of deformation of the steel pipe, so that the product will directly form a certain angle, and then reach its Bending purpose.
In the process of bending the pipe, the deformation of the steel pipe mainly occurs on the mold, and the upper mold plays the role of the tire, so that the curve of the product will be determined according to its different specifications and the critical value of the plastic deformation of the steel pipe of different materials. Corresponding to its different upper molds.
There are two reasons for the wrinkling of the elbow during the processing. We can effectively control it from two aspects. First, the inner tube of the elbow cannot be placed on the side close to the front clamp during the bending process. It should be placed close to the bottom. On one side of the mold bending cylinder, the rear of the inner tube effectively exceeds the rear of the upper tire by 1.5 cm.
During the bending process, we will find that the position of the inner tube shaft of the product is not easy to control, so after designing and making a positioning trolley, a small benchmark can be used to connect the inner tube and the trolley rigidly. When it coincides with the center of the upper die, record the relative position of the trolley.
