Technical Field

[0001] This utility model relates to the field of pipe bending machine mold technology, and in particular to CNC pipe bending machine molds used for hot bending. Background Technology

[0002] A pipe bending machine is an industrial device that uses localized heating of pipes to enhance their plasticity, thereby enabling them to bend easily and precisely into specific shapes. Its function is to process pipes into various complex bending shapes to meet the manufacturing needs of various piping systems in industries such as automobiles, aerospace, furniture, and machinery.

[0003] However, the existing pipe bending machine molds often have cumbersome clamping mechanism designs, resulting in low efficiency in clamping and fixing pipes, affecting the overall operating speed and posing safety hazards. High-temperature molds lack effective heat insulation measures, which can easily cause burns to operators. Furthermore, traditional bending mechanisms lack precise guidance, making it difficult to control the movement trajectory during the bending process. Ultimately, this leads to poor forming accuracy and product consistency, resulting in cost losses. Utility Model Content
