Pipe bending equipment and guide die arc reverse deformation mechanism for restraining bent pipes from changing into ellipses

Abstract

The invention discloses pipe bending equipment and a guide die arc reverse deformation mechanism for restraining bent pipes from changing into ellipses. The mechanism comprises a mounting frame, a fourth driving piece as well as a first guide die, a second guide die and a third guide die which are mounted on the mounting frame from top to bottom; the right end surface of the first guide die is provided with a linear first cambered surface, the right end surface of the second guide die is provided with a linear second cambered surface, and the right end surface of the third guide die is provided with a linear third cambered surface; the fourth driving piece is used for driving two of the first guide die, the second guide die and the third guide die to move up and down; then the first guide die, the second guide die and the third guide die are separated or closed, and when the first guide die, the second guide die and the third guide die are closed, the first cambered surface, the second cambered surface and the third cambered surface are matched to form a semi-elliptical groove. According to the technical scheme, the ellipse changing degree of the guide pipe during pipe bending operation can be effectively reduced.

AI Technical Summary

Benefits of technology

This patented technology allows for flexibility during medical procedures by allowing different parts or components on an IV device (catheters) to move along with each other without changing their shape when they are being used. By adjustably bending certain features at specific locations within these devices, it becomes easier to insert them into blood vessels due to its small size compared to traditional methods like pushing buttons through tubes.

Problems solved by technology

Technological Problem: The technical problem addressed by these inventions relates to improving the accuracy and stability of crimping processes when handling metallic materials like steel tubings (tubular) inside engine manifolds and valves. These structures often require precise measurements to prevent failure from leaks caused by cracks formed through stress corrosion cracking. However, current techniques involve manually inserting tiny particles into the material beforehand without adequate constraint, resulting in significant changes over time. Additionally, existing solutions only work well at specific temperatures but fail under certain circumstances where they could lose effectiveness.
