Pipe bending precision is a crucial indicator for measuring the quality of tubular sheet metal parts. Insufficient precision can easily lead to issues such as pipe ovality and wrinkling, which affect the assembly and use of products. The main causes of these problems are as follows: mismatched sizes between the pipe bending die and the pipe, excessively fast pipe bending speed, and uneven wall thickness of the pipe.
To avoid such problems, the following measures should be taken:
- Customize dedicated pipe bending dies according to the pipe specifications;
- Control the pipe bending speed to maintain stability;
- Select high-quality pipes with uniform wall thickness.
Meanwhile, a mandrel can be used for assistance during the pipe bending process to reduce the extrusion deformation of the pipe's inner wall. Our company's pipe bending equipment is equipped with a high-precision control system, which can adjust the pipe bending parameters in real time. Combined with strict raw material screening standards, it ensures that the bent pipes meet the roundness requirements, are free of wrinkles, and satisfy customers' high-precision assembly needs.
Key Terminology Explanation (for clarity in industrial context)
- Ovality: The deviation of a pipe's cross-section from a perfect circle, a common defect in bending.
- Mandrel: A cylindrical tool inserted into the pipe during bending to support the inner wall and prevent collapse/wrinkling.
- Pipe bending die: A specialized mold that determines the bending angle and shape of the pipe, requiring precise matching with pipe dimensions.
