Description

Technical Field

[0001] This invention relates to the field of porous copper tube forming, and more specifically, to a double-action reverse hot extrusion apparatus and method for producing porous copper tubes. Background Technology

[0002] Porous copper tubes, as an important functional structural material, are widely used in high-efficiency heat exchangers, microchannel cooling systems, fuel cell flow field plates, and high-end electronic heat dissipation devices. Their cross-sections typically contain two to dozens of precision internal holes, requiring accurate hole distribution, uniform wall thickness, smooth inner surfaces, and excellent mechanical and thermal conductivity. Hot extrusion has become the mainstream technology for manufacturing porous copper tubes due to its advantages such as achieving large plastic deformation, densification, and near-net-shape forming.

[0003] In existing technologies, copper tubes are generally extruded using a double-action reverse hot extrusion press. After extrusion, holes are drilled into the surface of the copper tube using drilling equipment to obtain a porous tube for subsequent use. However, copper tubes are generally thin, and direct drilling may result in insufficient filling inside the copper tube, causing the surface of the copper tube to collapse during drilling, thus reducing the processing quality of the copper tube.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

The surface of the support plate has auxiliary holes, which facilitate the drill rod of the drilling machine to pass through the support plate to drill holes in the copper tube. After drilling, the drilling machine is reset, thus avoiding the problem that direct drilling of copper tubes with thin walls may lead to insufficient filling inside the copper tube, causing the surface of the copper tube to collapse during drilling, thereby reducing the processing quality of the copper tube.

Detailed Implementation

[0020] The invention will now be further described with reference to the accompanying drawings and specific embodiments: Example 1, please refer to Figure 1-12 According to an embodiment of the present invention, a double-action reverse hot extrusion apparatus for producing porous copper tubes includes a support base 1, a double-action hot extrusion device 2 disposed on the surface of the support base 1, a fixing plate 3 disposed on the side of the double-action hot extrusion device 2, a first electric push rod 4 disposed on the surface of the fixing plate 3, a support frame plate 5 disposed on the lifting end of the first electric push rod 4, a mounting frame 6 disposed at the bottom of the support frame plate 5, and an auxiliary plate 7 disposed on the side of the support frame plate 5. The auxiliary plate 7 is provided in two sets, one set of which is provided with a guide rod 8 on the side, and the other set of which is provided with a positioning bearing 9 on the side. A support screw 10 is inserted into the positioning bearing 9. The first electric push rod 4 facilitates the height adjustment of the mounting frame 6 and the support plate 22, thereby facilitating the subsequent movement of the perforated copper tube.

[0021] The mounting bracket 6 has a lifting groove 11 on its surface, and a limit bearing 12 is provided on the surface of the lifting groove 11. A lifting screw 13 is inserted into the limit bearing 12. A motor frame 14 is provided on the side of the mounting bracket 6, and a drive motor 15 is provided on the surface of the motor frame 14. The drive motor 15 facilitates the subsequent rotation of the lifting screw 13, thereby cooperating with the lifting groove 11 to limit the lifting plate 16, which facilitates the subsequent height adjustment of the lifting plate 16 and the subsequent drilling of holes in the copper tube surface using the drilling machine 20.

[0022] A lifting plate 16 is screwed onto the surface of the lifting screw 13. A mounting base plate 17 is provided on the side of the lifting plate 16. A positioning slot 18 is provided on the surface of the mounting base plate 17. A positioning block 19 is provided in the positioning slot 18. A drilling machine 20 is provided on the side of the positioning block 19. A movable plate 21 is provided below the mounting frame 6. A support plate 22 is provided on the side of the movable plate 21. The support plate 22 is used to support the inside of the copper tube and avoid the problem of the copper tube surface being dented when the drilling machine 20 drills the copper tube. The height of the lifting plate 16 can be easily adjusted by rotating the lifting screw 13, thereby facilitating the height adjustment of the drilling machine 20 for drilling.

[0023] The first electric push rod 4 is fixedly connected to the surface of the fixed plate 3. The fixed plate 3 is integrally in the shape of a "C"-shaped plate structure. A bearing plate 23 is arranged on the surface of the support plate 5. The bearing plate 23 is integrally in the shape of a "T"-shaped plate structure. An auxiliary rod 45 is arranged on the surface of the mounting base plate 17. One end of the auxiliary rod 45 passes through the support plate 5. One end of the lifting screw rod 13 is fixedly connected to the inner ring surface of the limit bearing 12. The other end of the lifting screw rod 13 is sleeved with a first gear 24. The driving end of the driving motor 15 is provided with a second gear 25. The first gear 24 and the second gear 25 are meshed and传动. By starting the driving motor 15 to drive the second gear 25 to rotate, the engagement of the second gear 25 and the first gear 24 is used to facilitate driving the lifting screw rod 13 to rotate, so as to facilitate driving the lifting plate 16 to adjust the height. The setting of the bearing plate 23 enables the bearing plate 23 to be placed on the upper surface of the fixed plate 3, which is convenient for reducing the pressure on the lifting end of the first electric push rod 4 through the cooperation of the bearing plate 23 and the fixed plate 3.

[0024] Please refer to Figure 8 and Figure 9 As shown, the mounting base plate 17 is fixedly connected to the side surface of the lifting plate 16. Multiple groups of positioning card slots 18 are provided. The multiple groups of positioning card slots 18 are linearly arranged at equal intervals on the surface of the mounting base plate 17. Through holes 26 are provided on the surface of the positioning card slots 18. Two groups of positioning blocks 19 are provided. The two groups of positioning blocks 19 are symmetrically distributed with respect to the drilling machine 20. The positioning blocks 19 are fixed in the positioning card slots 18 by positioning bolts 27. Multiple groups of positioning card slots 18 are provided, which is convenient for subsequently installing the positioning blocks 19 in different positioning card slots 18, so as to adjust the distance between the drilling machines 20, so as to facilitate opening holes with different distances on the surface of the copper pipe for convenient use.

[0025] Embodiment 2, please refer to Figures 6-12 It should be noted that there is an incorrect character "传动" in the translation of the first paragraph, which should probably be "传动" (the correct English might be "transmission" or other appropriate terms depending on the context). You may want to double-check the original text for accuracy.As shown, the double-acting hot extrusion equipment 2 has a conveyor frame 28 on its side. A hole is opened on the side of the conveyor frame 28, and a bearing 29 is installed inside the hole. A limit rod 30 is fixedly connected to the inner ring of the bearing 29. A traction wheel 31 is installed on the end face of the limit rod 30. A guide rod 8 passes through the mounting frame 6, and a scale 40 is installed on the surface of the guide rod 8. The mounting frame 6 rests on the support screw 10, and a positioning bearing 9 is also fitted on the other end of the support screw 10. An auxiliary support frame 41 is installed on the surface of the positioning bearing 9. One end of the guide rod 8 passes through the auxiliary support frame 41. After the copper tube is processed and extruded, the copper tube is positioned under the traction wheel. The traction wheel 31 rotates in conjunction with the bearing 29 on the surface of the guide wheel 31, which helps to reduce the friction on the surface of the copper tube. In addition, when different lengths of copper tubes are needed, the support screw 10 is rotated in conjunction with the positioning bearing 9, thereby causing the mounting bracket 6 screwed on the support screw 10 to move. The guide rod 8 supports the mounting bracket 6 on the one hand, and prevents the mounting bracket 6 from rotating when the support screw 10 is rotated on the other hand. Moreover, the movable scale 40 set on the surface of the guide rod 8 makes it easy to quickly and clearly see the displacement distance of the mounting bracket 6, thus making it convenient to obtain the required length of copper tube.

[0026] Please see Figures 4-11 The conveyor frame 28 is provided with a limit plate 32 on its side. The limit plate 32 is in the shape of an "L" and has an "L" shaped plate structure. The moving plate 21 is provided with a handrail 33 on its side. The surface of the handrail 33 has a positioning hole, into which a limit pin 34 is inserted. One end of the limit pin 34 is inserted into the limit plate 32. The bottom of the mounting frame 6 is fixedly connected to a rotating rod 35. An auxiliary bearing 36 is sleeved on the surface of the rotating rod 35. A support block 37 is fixedly connected to the outer ring surface of the auxiliary bearing 36. The support block 37 is fixedly connected to the side of the moving plate 21. A limit switch 3 is provided on the side of the moving plate 21. 8. Limit switch 38 is electrically connected to double-action hot extrusion equipment 2. When the end face of the copper tube touches the limit switch 38, the double-action hot extrusion equipment 2 stops working, which facilitates the subsequent drilling of the copper tube. After the copper tube is drilled and cut, the copper tube is moved upward by the first electric push rod 4, and then one end of the limit pin 34 is pulled out from the limit plate 32, which can then remove the limit on the moving plate 21. Then, it can be rotated in conjunction with the auxiliary bearing 36, so that the drilled copper tube can be rotated out, which makes it easy to remove the drilled copper tube.

[0027] The support plate 22 is fixedly connected to the side of the movable plate 21. The support plate 22 has an arc-shaped plate structure. The surface of the support plate 22 is provided with auxiliary holes 39. Multiple sets of auxiliary holes 39 are arranged linearly at equal intervals about the surface of the support plate 22. The side of the support base 1 is provided with a base plate 42. The surface of the base plate 42 is provided with a second electric push rod 43. The lifting end of the second electric push rod 43 is provided with a copper tube cutter 44. The auxiliary holes 39 on the surface of the support plate 22 correspond to the through holes 26 on the surface of the positioning slot 18. When the copper tube is cut, the second electric push rod 43 can be activated to move the copper tube cutter 44 upward, so that the copper tube can be cut by the copper tube cutter 44.

[0028] A method for producing porous copper tubes by double-action reverse hot extrusion specifically includes the following steps: S1. First, the raw material is fed into the double-acting hot extrusion equipment 2 and extruded by the double-acting hot extrusion equipment 2 to facilitate the processing of copper tubes by the double-acting hot extrusion equipment 2. S2. The copper tube is extruded and displaced onto the support plate 22, and the support plate 22 is used to support the inside of the copper tube. S3. Start the drive motor 15 and use the meshing of the first gear 24 and the second gear 25 to drive the lifting screw 13 to rotate, so that the height of the lifting plate 16 can be adjusted, making it easier to move the drilling machine 20 down and use the drilling machine 20 to open holes on the surface of the copper tube. S4. Finally, after drilling the copper tube, the copper tube is cut by the copper tube cutting machine 44. After cutting, the lifting plate 16 is moved upward so that the drilling machine 20 will not affect the subsequent removal of the perforated copper tube. Through the above-described scheme of the present invention, the copper tube is extruded and formed by a double-action hot extrusion equipment 2. After the copper tube is extruded and formed, it is fitted onto a support plate 22. The support plate 22 supports the inside of the copper tube. Then, the drive motor 15 is started to drive the lifting screw 13 to rotate, thereby adjusting the height of the lifting plate 16. This facilitates the drilling machine 20 to move down and drill holes in the supported copper tube. The support plate 22 has auxiliary holes 39 on its surface, which facilitates the drill rod of the drilling machine 20 to pass through the support plate 22 to drill holes in the copper tube. After drilling, the drilling machine 20 is reset, thus avoiding the problem that direct drilling of copper tubes with thin walls may lead to insufficient filling inside the copper tube, causing the surface of the copper tube to collapse during drilling, thereby reducing the processing quality of the copper tube.

Start the drive motor (15) and use the meshing of the first gear (24) and the second gear (25) to drive the lifting screw (13) to rotate, so that the height of the lifting plate (16) can be adjusted, making it easier to move the drilling machine (20) down and use the drilling machine (20) to open holes on the surface of the copper tube. S4. Finally, after drilling the copper tube, the copper tube is cut by the copper tube cutting machine (44). After cutting, the lifting plate (16) is moved up so that the drilling machine (20) will not affect the subsequent removal of the multi-hole copper tube with the hole.
