Description

TECHNICAL FIELD

[0001] The utility model relates to mould processing technical field, concretely is a kind of high-precision parts processing bending die. BACKGROUND

[0002] Part bending is used for processing metal plate or pipe, and is a tool for bending into the required shape by applying pressure on it. These devices are usually made of high-strength metal or alloy, which can withstand high pressure and frequent use without deformation or damage.

[0003] Under prior art, when bending pipe parts using prior art, the common practice is to fix one end of the pipe, and then apply force to the other end to make it bend. Although this method is widely used, it also has some disadvantages and limitations, and stress concentration problems may occur near the bending point of the pipe. Since the bending point is the force concentration point, it may cause excessive stress near this point, thereby increasing the risk of pipe deformation or even rupture. During the bending process, especially near the bending point, uneven bending quality may occur. This may result in inaccurate or non-compliant geometry of the bent part, especially for industrial applications that require high precision. The single-point bending method usually limits the bending complexity and shape that can be achieved. Certain complex shapes or small-radius bends may not be achievable through this method, which is a limitation for certain applications that require high design requirements. Due to stress concentration and deformation near the bending point, the original circular cross-section of the pipe may be deformed or distorted, which may affect the functionality and aesthetics of the pipe.
