[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] according to Figure 1-3 This utility model provides a copper tube straightening and rounding assembly, including: a base 1, a guide sleeve 2, a horizontal straightening wheel 3, a vertical straightening wheel 4, a positioning rod 5, a positioning plate 6, a placement opening 7, and a straightening roller 8.

[0020] Guide sleeve 2 is mounted on one side of base 1. Horizontal straightening roller 3 is mounted on base 1. Horizontal straightening roller 3 is mounted on one side of guide sleeve 2. Rounding roller 8 is mounted between horizontal straightening roller 3 and guide sleeve 2. Vertical straightening roller 4 is mounted on the side of horizontal straightening roller 3 away from guide sleeve 2.

[0021] When straightening and rounding a copper tube is required, the copper tube is inserted through the guide sleeve 2, allowing it to move along the direction of the guide sleeve 2 for initial straightening. It then moves along the corresponding path to the rounding roller 8, where it is compressed into a suitable circle. The tube then continues to move sequentially to the horizontal straightening roller 3 and the vertical straightening roller 4, straightening any bends. Finally, the tube exits from the base 1 away from the guide sleeve 2, achieving the desired straightened shape. This invention, through the aforementioned components, allows bent copper tubes to be straightened, facilitating their application on other equipment. It also allows for rounding, increasing the accuracy of the copper tube and making connection and installation more convenient.

[0022] There are several horizontal straightening wheels 3. Each horizontal straightening wheel 3 has a groove on its side. There are several vertical straightening wheels 4. Each vertical straightening wheel 4 has a groove on its side. A positioning plate 6 is located on the side of the horizontal straightening wheel 3 away from the guide sleeve 2. The positioning rod 5 includes: a horizontal positioning rod 51 and a vertical positioning rod 52. The horizontal positioning rod 51 is located on the base 1. The vertical positioning rod 52 is located on the positioning plate 6. The horizontal straightening wheels 3 are rotatably mounted on the horizontal positioning rod 51. The horizontal straightening wheels 3 are staggered on both sides of the base 1. The vertical straightening wheels 4 are rotatably mounted on the vertical positioning rod 52. The vertical straightening wheels 4 are staggered on both sides of the positioning plate 6.

[0023] The horizontal straightening roller 3 has grooves on its sides, and the horizontal straightening rollers 3 are staggered on both sides of the base 1. When viewed from one side of the base, the grooves of the horizontal straightening rollers 3 on both sides appear to be visually combined, forming a circle in the middle. This circle corresponds to the required specifications of the copper tube. When the copper tube passes through the horizontal straightening rollers 3, both sides of the copper tube come into contact with the horizontal straightening rollers 3 on both sides of the base 1. If the specifications of the copper tube do not match the requirements, it will be contacted by the horizontal straightening rollers 3, causing its curved sides to be squeezed. Similarly, the vertical straightening roller 4 can also cause the copper tube to be contacted and squeezed, so that the sides of the copper tube are squeezed into a structure that meets the requirements. Through the cooperation of the horizontal straightening rollers 3 and the vertical straightening rollers 4, the curved surface of the copper tube is contacted, straightening it into a suitable straight copper tube. The horizontal straightening roller 3 and the vertical straightening roller 4 are arranged on both sides so that the sides of the copper tube are evenly squeezed. Since there are multiple straightening rollers, the copper tube can be straightened multiple times from entering the guide sleeve 2 to finally leaving, so that the straightening effect of the copper tube is better.

[0024] The placement port 7 is located on the base 1. The placement port 7 is located on the side of the horizontal straightening wheel 3 away from the guide sleeve 2. The placement port 7 is on the same side as the vertical straightening wheel 4. There are two rounding rollers 8. The two rounding rollers 8 are tangent to each other. The sides of the rounding rollers 8 have grooves. The grooves of the two rounding rollers 8 correspond to each other. The guide sleeve 2 includes: a guide cylinder 21 and a transition block 22. The guide cylinder 21 is positioned opposite each other on both sides of the transition block 22. The transition block 22 has a feeding cavity 221. The feeding cavity 221 is connected to the guide cylinder 21.

[0025] Horizontal straightening roller 3 and vertical straightening roller 4 are mounted on base 1. Due to their different mounting methods, their heights also differ. Since vertical straightening roller 4 is longer in the vertical direction, to keep the copper tube horizontal when passing through this invention, the height of horizontal straightening roller 3 and guide sleeve 2 needs to be increased, which is more complicated. This invention provides a placement opening 7 on base 1, allowing one end of vertical straightening roller 4 to extend into the placement opening 7 near base 1. This allows the height of vertical straightening roller 4 to be lowered without interfering with base 1, making the manufacturing process more convenient. The two rounding rollers 8 of this invention are tangent to each other. The sides of the rounding rollers 8 have grooves, which correspond to each other. When the two grooves meet, they form a circle. After the copper tube passes through guide sleeve 2, it reaches the rounding roller 8 and passes through this circle. The rounding roller 8 causes the copper tube to be rubbed and squeezed as it passes through this circle, causing some uneven parts on the surface of the copper tube to be rubbed into a suitable shape. The guide sleeve 2 of this utility model includes a guide cylinder 21 and a transition block 22. When the copper tube passes through, it first enters from one guide cylinder 21, then enters the transition block 22, and then enters the other guide cylinder 21. The transition block 22 has an inlet cavity 221. When the copper tube passes through this utility model, some uneven parts may rub against various structures. If the friction is too great, these structures may be worn. In actual use, lubricating oil or other liquids can be introduced into the inlet cavity 221 to reduce the friction between the copper tube and these structures. Moreover, the rounding and straightening process of the copper tube is mainly extrusion molding and will not be greatly affected.

[0026] Working principle and usage process of this utility model:

[0027] When it is necessary to straighten and round the copper tube, the copper tube is inserted into the guide cylinder 21 on one side of the guide sleeve 2, and lubricating oil is introduced into the feed chamber 221 of the transition block 22. After the copper tube passes through the guide cylinder 21, it reaches the feed chamber 221 and is coated with oil. Then it continues to move to the other guide cylinder 21 and moves towards the rounding roller 8. When the copper tube reaches the rounding roller 8, it extends into the groove of the two rounding rollers 8 and is rounded by the rounding roller 8. Then the copper tube reaches the horizontal straightening roller 3, so that the two sides of the copper tube in the horizontal direction are squeezed by the horizontal straightening roller 3 respectively. Then the copper tube reaches the vertical straightening roller 4, so that the two sides of the copper tube in the vertical direction are squeezed by the vertical straightening roller 4. After the squeezing is completed, the copper tube leaves from the side of the base 1 away from the guide sleeve 2, and the copper tube that meets the requirements can be obtained.

[0028] In summary, this utility model, by setting up horizontal and vertical straightening wheels, enables bent copper tubes to be straightened into straight lines, facilitating their application on other equipment. Furthermore, it is equipped with rounding rollers to round the tubes, resulting in higher precision and making the connection and installation process more convenient.

[0029] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
