Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, in particular to a copper tube processing and bending device. Background Art

[0002] Copper tube is also called red copper tube. It is a kind of non-ferrous metal tube, which is a pressed and drawn seamless tube. Copper tube has good electrical and thermal conductivity. It is the main material of the conductive parts and heat dissipation parts of electronic products. When the copper tube is used with the radiator, it needs to be bent. At this time, the copper tube will be processed by the bending device.

[0003] After searching, the existing Chinese patent announcement number is: CN218486946U, which provides a bending device for processing radiator copper tubes. When the copper tube body needs to be processed, the second clamping plate can be held by hand to apply force away from the first clamping plate to be in an unfolded state. At this time, the copper tube body is placed between the first clamping plate and the second clamping plate. At this time, the force applied to the second clamping plate is cancelled, so that the second clamping plate can slide on the surface of the fixed rod through the pressure of the first spring. When the second fixed plate moves, the second clamping plate will apply force to the copper tube body. The second clamping plate can cooperate with the first clamping plate to limit the copper tube body, thereby achieving the effect of facilitating limiting and preventing the copper tube body from being dislocated during processing, thereby affecting the use effect.

[0004] Although the above patent can limit the copper tube body, the above device still has the following problems: during the bending process of the copper tube, the device needs to cooperate with the first clamping plate to limit the copper tube body through the second clamping plate, but since the device can only limit a few copper tubes at a time, the device cannot process multiple copper tubes at the same time, so that the efficiency of the copper tube processing by the device is low and the scope of use of the device is reduced. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content
