[0002] Copper pipe is also called red copper pipe. It is a kind of non-ferrous metal pipe, which is a pressed and drawn seamless pipe. Copper pipe has good electrical and thermal conductivity. It is the main material for the conductive accessories and heat dissipation accessories of electronic products. It has become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. Copper pipe has strong corrosion resistance, is not easy to oxidize, and is not easy to react chemically with some liquid substances. It is easy to bend and shape.

[0014] 3. Beneficial effects

[0015] (1) In the process of bending the copper tube of the present invention, the copper tube is bent along the guide groove uniformly welded on the top of the bending plate, so that the guide groove guides the copper tube during the bending process, thereby preventing the copper tube from being displaced at the bending part during the bending process, thereby affecting the installation effect.

After the simmering is completed, it can be directly installed, and then the next section of work can be carried out. There is no need to inspect the welding, and the pollution caused by the construction is also reduced.

[0017] (3) The present invention also arranges the bending plate in a semicircular structure so that the angles at both ends of the bending plate are 360°, allowing workers to bend the cylinder into a U-shaped structure during the bending process of the copper tube, so that the copper tube can be bent at any angle between 90 and 180 degrees after bending, thereby saving materials and accessories, reducing pollution caused by copper tube welding, and also saving more labor for facilitating copper tube connection and installation.

[0018] (4) In the process of limiting the position of the copper tube by the second fixed tube clamp and the first fixed tube clamp of the present invention, the elasticity of the first return spring and the arc-shaped limit block are used to clamp the copper tube to prevent the staff from causing displacement during the bending process of the copper tube, thereby affecting the bending effect. At the same time, the copper tube is inserted from the position of the second fixed tube clamp and received in the tube-bearing groove opened on the inclined surface of the receiving seat, and the bottom of the copper tube is supported by the truncated cone-shaped tube-bearing groove which is wide at the top and narrow at the bottom. At the same time, the truncated cone-shaped structure which is wide at the top and narrow at the bottom can automatically adapt to pipes of different sizes, and is easy to use. At the same time, the required angle is adjusted in advance by the arc-shaped block and the corresponding arc-shaped groove on the slide rail, and the receiving seat is limited to prevent displacement during the bending process of the copper tube, thereby affecting the bending effect, and is easy to use.
