Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, and in particular to a circular copper tube pressing and forming device. Background Technology

[0002] The metal sheet (usually an aluminum sheet or aluminum alloy sheet) is first milled with a serpentine or rectangular groove that matches the outer diameter of the copper tube. Then, the copper tube is embedded into the groove by mechanical pressure. The key function of this process is to ensure that the outer wall of the copper tube fits tightly against the wall of the metal plate groove, minimizing gaps. Since the thermal conductivity of copper and aluminum differs greatly (copper is about 400 W / (m·K), and aluminum is about 180 W / (m·K)), any gaps will significantly increase the thermal resistance of the "metal sheet → copper tube". Through precise pressing, the contact thermal resistance can be reduced to below 0.01℃ / W, laying the foundation for efficient heat exchange.

[0003] In existing technologies, stamping is usually done with a punch press, which results in poor forming effect and uneven copper tube surface, leading to large deformation of the cold plate on which the copper tube is placed. Therefore, by changing the stamping to hydraulic pressure, the deformation of the cold plate on which the copper tube is placed is reduced by pressing down on the copper tube position by position, and the overall flatness of the copper tube is higher with smaller error.

[0004] However, after each single-point pressing is completed, the cold plate needs to be manually moved to move the next copper tube to be pressed under the pressing block. This operation method is extremely labor-intensive: the cold plate and copper tube components usually have a certain weight, and frequent manual adjustment not only requires operators to expend a lot of physical strength, but also easily causes operator fatigue, especially in large-scale production scenarios, further reducing the production pace. Moreover, when the hydraulic equipment is in operation, close-range manual operation can easily cause injury such as squeezing or collision to the operator if the equipment moves unexpectedly, such as the hydraulic system being accidentally triggered, posing a great threat to production safety. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that manually adjusting the position of the copper tube by pressing it is not only labor-intensive but also poses safety hazards.

[0020] Example like Figures 1-5 As shown, this utility model provides a technical solution: a circular copper tube pressing and forming device, including a fixed base 1, which serves as the basic load-bearing component of the entire device and provides stable support for the various mechanisms above. A moving mechanism is provided above the fixed base 1 to realize the horizontal movement and rotation adjustment of the cold plate.

[0021] The moving mechanism includes an operating table 2 mounted on a fixed base 1, which provides an installation platform for the moving mechanism. A moving groove 21 is provided on the upper surface of the operating table 2. The moving groove 21 provides a guide rail for the sliding of the threaded block 24. A lead screw 22 is rotatably mounted in the moving groove 21 through a bearing. One end of the lead screw 22 passes through to one side of the operating table 2 and is fixedly connected to a drive handwheel 23. By rotating the drive handwheel 23, the lead screw 22 can be rotated, realizing precise control of manual adjustment.

[0022] A threaded block 24 is fitted on the lead screw 22 and is threaded to engage with it. The outer side of the threaded block 24 is slidably engaged with the inner wall of the moving groove 21. When the lead screw 22 rotates, the threaded block 24 moves horizontally in a straight line along the moving groove 21. A moving plate 25 is fixedly connected to the upper end of the threaded block 24, so that the moving plate 25 can move synchronously with the threaded block 24 to realize the horizontal position adjustment of the cold plate.

[0023] The lower surface of the movable plate 25 is also fixedly installed with symmetrically distributed movable sleeves 26. The inner wall of the movable sleeve 26 is slidably fitted with linear guide rails 27. Both linear guide rails 27 are fixedly installed on the operating table 2. Through the cooperation of the movable sleeves 26 and the linear guide rails 27, the stability of the movable plate 25 during movement is effectively enhanced, avoiding tilting caused by uneven force, and ensuring the horizontal movement accuracy of the cold plate.

[0024] An adjustment housing 28 is also fixedly installed on the movable plate 25. The adjustment housing 28 serves as the mounting carrier for the rotary adjustment component. A vertically extending drive rod 29 is rotatably installed inside the adjustment housing 28 via a bearing. A worm gear 210 is fixedly sleeved on the drive rod 29. The upper end of the drive rod 29 penetrates the top surface of the adjustment housing 28 and extends upward to transmit rotational power.

[0025] A servo motor 211 is also installed inside the adjusting housing 28. The servo motor 211 serves as the power source for rotational adjustment. The output shaft of the servo motor 211 is fixedly mounted with a worm gear 212 via a coupling. The outer surface of the worm gear 212 meshes with the tooth surface of the worm wheel 210, forming a reduction transmission structure. Through precise control of the servo motor 211, the drive rod 29 can be rotated at a fixed angle to meet the pressing requirements of different positions on the cold plate.

[0026] An annular guide rail 213 is fixedly installed on the upper end of the adjusting housing 28. The center of the annular guide rail 213 and the center of the drive rod 29 are on the same vertical line. An arc-shaped support sliding sleeve 214 is slidably sleeved on the outside of the annular guide rail 213. The cooperation between the annular guide rail 213 and the arc-shaped support sliding sleeve 214 provides stable support for the rotation of the placement plate 3, avoids shaking during rotation, and ensures the accuracy of the pressing position.

[0027] A fixing mechanism is provided above the operating table 2. The fixing mechanism is used to fix the cold plate and realize the pressing operation. The fixing mechanism includes a placement plate 3. The placement plate 3 is fixedly connected to the arc-shaped support sliding sleeve 214 and the drive rod 29. It can rotate synchronously with the drive rod 29 and is kept stable by the arc-shaped support sliding sleeve 214.

[0028] The upper end of the placement plate 3 is provided with symmetrically distributed travel grooves 31. The axial direction of the travel grooves 31 is consistent with the radial direction of the placement plate 3. A screw 32 is rotatably installed in the travel grooves 31 through bearings. One end of the screw 32 passes through to the side of the placement plate 3 and is fixedly connected to a grip handle 33. A moving block 34 is threadedly connected to the screw 32. The moving block 34 slides with the travel grooves 31. A clamping plate 35 is fixedly connected to the upper end of the moving block 34.

[0029] Rotating the grip handle 33 drives the screw 32 to rotate, causing the moving block 34 to move along the stroke groove 31, which in turn drives the clamping plate 35 to clamp and fix the cold plate, preventing molding errors caused by displacement of the cold plate during the pressing process.

[0030] A mounting bracket 36 is also fixedly installed on the fixed base 1. A hydraulic cylinder 37 is fixedly installed on the upper end of the mounting bracket 36. The hydraulic cylinder 37 is located above the placement plate 3, and the piston rod of the hydraulic cylinder 37 passes through the mounting bracket 36 and extends vertically downward. A cylindrical pressing block 38 is also installed on the extended end of the piston rod of the hydraulic cylinder 37.

[0031] The hydraulic cylinder 37 provides stable pressing power, and the cylindrical pressing block 38 achieves precise single-point pressing of the copper tube, ensuring that the copper tube and the metal plate are tightly bonded and reducing contact thermal resistance.

[0032] It should be noted that the electrical components mentioned above are all existing mature technologies, and appropriate models and power can be selected based on the technical knowledge of those skilled in the art, so they will not be described in detail here.

[0033] The working process of this utility model: Step one: First, place the cold plate to be pressed on the placement plate 3. Then, operate the handles 33 on both sides. The handles 33 drive the screw 32 to rotate. Since the screw 32 is fitted with a moving block 34 that is threaded to it, the rotation of the screw 32 will cause the moving block 34 to move along the travel groove 31. The clamping plate 35 fixedly connected to the upper end of the moving block 34 will also move accordingly, thereby clamping and fixing the cold plate on both sides to ensure that the cold plate is stable in position and will not shift during subsequent pressing. Next, rotate the drive handwheel 23. The drive handwheel 23 drives the lead screw 22 to rotate. The lead screw 22 is fitted with a threaded block 24 that is threaded to it. The lead screw 22 rotates... The threaded block 24 moves along the moving groove 21, and the moving plate 25 at the upper end of the threaded block 24 moves accordingly. At this time, the moving sleeve 26 at the lower end of the moving plate 25 slides on the inner wall of the linear guide rail 27 to ensure the stability of the moving plate 25. When the moving plate 25 moves, it drives the cold plate above to move, so that the outer edge of the cold plate moves to below the cylindrical pressing block 38. Then, through the external hydraulic system and control handle, the hydraulic cylinder 37 is activated. The piston rod of the hydraulic cylinder 37 drives the cylindrical pressing block 38 to extend and press the cold plate at a small single point. After the pressing is completed, the piston rod of the hydraulic cylinder 37 retracts, and the cylindrical pressing block 38 returns to the initial position. Step two: After the initial pressing, the servo motor 211 is started. The output shaft of the servo motor 211 drives the worm gear 212 to rotate through the coupling. The outer surface of the worm gear 212 meshes with the tooth surface of the worm wheel 210 fixedly sleeved on the outside of the drive rod 29. The rotation of the worm gear 212 drives the worm wheel 210 to rotate, which in turn causes the drive rod 29 to rotate. The placement plate 3 fixedly connected to the upper end of the drive rod 29 also rotates accordingly. At the same time, the arc-shaped support sliding sleeve 214, which is slidably sleeved on the outside of the annular guide rail 213 at the lower end of the placement plate 3, slides on the annular guide rail 213 to ensure the stability of the rotation of the placement plate 3. After the placement plate 3 drives the cold plate to rotate at a specified angle, the hydraulic cylinder 37 is started again to press the next position of the cold plate. This process is repeated until the entire outer side of the cold plate is pressed. Step 3: After the entire outer side of the cold plate has been pressed, start the drive handwheel 23 again to move the cold plate. At the same time, cooperate with the rotation of the placement plate 3 to press the cold plate from all directions, ensuring that all areas of the cold plate are pressed evenly and effectively until the entire cold plate is pressed. The whole process does not require manual operation, which reduces labor costs, eliminates production safety hazards, and ensures high efficiency and safety in production.
