Description

[0001] Technical field.

[0002] This utility model relates to the field of copper pipe bending technology, and in particular to an automatic traction mechanism for copper pipe bending.

[0003] Background technology.

[0004] Copper pipe is a non-ferrous metal pipe with excellent electrical and thermal conductivity, and is often used in conductive and heat dissipation components of electronic products. Copper pipe also has the characteristics of being strong and corrosion resistant, so it is often used in the installation of water supply, heating and cooling pipes in buildings, making it the preferred material for piping systems in modern residential buildings.

[0005] In copper tube production, bending is often required due to varying pipeline configurations. During bending, one end of the copper tube is first fixed, and the other end is then secured to a traction mechanism. However, because the bending power component is fixed in position, the copper tube is held in place by a single clamping device. For copper tubes with significantly different radii, the same traction mechanism may not be suitable. This is because excessively large or small radii will deviate considerably after clamping, causing a shift in the traction force and affecting the bending effect. Therefore, we propose an automatic traction mechanism for copper tube bending to address these issues.

[0011] A second slot corresponding to the first slot is provided on the operating table. The second slot runs through the operating table, and a drive mechanism is installed at the bottom of one of the movable seats.

[0015] Preferably, the driving mechanism comprises a second driving motor, a driving shaft is arranged on the top of the second driving motor, and the driving shaft is coaxially fixed with the connecting column.
