Description

Technical Field

[0001] The present invention relates to the technical field of heat pipes, and in particular to a method for preparing a heat pipe material with grooves. Background Art

[0002] A heat pipe heat exchanger is a heat exchanger composed of independent closed tubes that transfer heat by boiling the working fluid at one end and condensing at the other end. It uses spirally wound metal bellows as heat exchange tubes, which not only greatly increases the heat exchange contact area and distance of the heat exchange working fluid, greatly improving the heat exchange effect, but also greatly reduces the flow resistance and pressure energy consumption of the heat exchange working fluid, thereby greatly improving the heat exchange efficiency and saving energy. It can be widely used in various heat exchange equipment and devices such as air conditioners, refrigerators, cold storages, water heaters, drying boxes, dryers, etc. for heating, cooling or refrigeration. At present, the heat pipe is made by burning a layer of copper powder inside to produce a capillary structure on the inner wall of the heat pipe. The capillary structure facilitates the flow of the working medium. If you drop a drop of water on a smooth surface, the water will gather and not flow, but if you drop it on the capillary structure surface, the water will quickly flow to the surroundings.

[0003] During the production of existing heat pipes, a layer of copper powder is fired inside the heat pipe, which has a high production cost. In addition, burrs will appear on the cross-section of the pipe when the pipe is cut. When the pipe is transported, workers are easily injured. In addition, when the pipes are stacked, the pipes are directly stacked on the stacking rack, which is relatively messy and not conducive to pipe storage.

[0017] This solution also provides a method for preparing a heat pipe material with a groove, the method comprising the following steps:

[0018] S1. First, the staff installs the workpiece on the loading roller. Then, the active roller works to continuously feed the workpiece. Next, the distance between the smooth roller and the rolling roller is adjusted according to the thickness of the workpiece. The staff rotates the handwheel, which drives the adjusting screw to rotate. The adjusting screw drives the rolling roller and the smooth roller to move relative to each other through the lifting block, realizing the rolling operation of workpieces of different thicknesses and preventing the stripes of the workpiece from being too shallow or too deep.

[0019] S2. Next, the workpiece is subjected to a rolling texturing operation. The workpiece is flattened by a leveling roller. Then, a smooth roller and a rolling roller are used to roll the top surface of the workpiece into a striped shape. Then, a laser texturing machine is used to texturize the top surface of the workpiece to form grooves, forming a capillary structure. The workpiece is processed by the rolling roller and the laser texturing machine in combination to form spiral and linear grooves on the surface of the workpiece.

[0020] S3. Then, the plate-shaped workpiece is subjected to a tubular forming operation. The workpiece passes through five sets of forming rollers in sequence. The five sets of forming rollers curl the workpiece to achieve the tubular forming operation of the workpiece.

[0021] S4. Next, a welding cooling operation is performed on the connection part of the workpiece.

Then, the leveled workpiece enters the water tank, and the cooling water in the water tank is sprayed out from the water nozzle by a water pump in the water tank to cool the welding part of the workpiece.

[0022] S5, then, the workpiece is fed and cut, the servo motor drives the feeding screw to rotate, and the feeding screw rotates and drives the cutting frame to slide along the top of the cutting feeding frame at the same speed as the workpiece, so that the cutting frame and the workpiece are in a relatively stationary state. At the same time, the pneumatic push rod works to drive the sliding tooth plate at the top of the slide to slide, and the sliding tooth plate drives the gear disk to rotate, and the rotation of the gear disk drives the cutting guide groove to rotate, and the rotation of the cutting guide groove drives the first telescopic slide to slide along the limit groove of the outer wall of the fixed disk through the cutting guide column. The sliding of the first telescopic slide drives the cutting machine to cut the workpiece, and then, the pneumatic push rod pushes the slide in the opposite direction to make the gear disk rotate in the opposite direction, and the reverse rotation of the gear disk drives the grinding guide groove to rotate, and the rotation of the grinding guide groove drives the second telescopic slide to slide along the limit groove of the outer wall of the fixed disk through the grinding guide column.

[0023] S6. Finally, the workpieces are stacked in an orderly manner. The positioning motor drives the rotating guide post on the top of the rotating disk to rotate.

At the same time, the rotation of the rotating disk drives the limit disk to fit with the limit guide groove, so as to realize the stable intermittent rotation of the rotating ratchet. The rotation of the rotating ratchet drives the stacking rack to slide intermittently along the top of the positioning frame through the intermittent gear and the positioning tooth plate.

[0024] Compared with the prior art, the present invention provides a method for preparing a heat pipe material with a groove, which has the following beneficial effects:

[0025] 1. The heat pipe with grooves is equipped with a laser texturing machine and a rolling roller. The workpiece is flattened by a flattening roller, then rolled by a smooth roller and a rolling roller to form stripes on the top surface of the workpiece. The workpiece is then laser texturing by a laser texturing machine, which carves grooves on the top surface of the workpiece to form a capillary structure. The capillary structure facilitates the flow of the working medium. If a drop of water is dropped on a smooth surface, the water will gather and not flow. However, if it is dropped on a capillary structure surface, the water will quickly flow to the surrounding area. The workpiece is processed by the combination of the rolling roller and the laser texturing machine, and spiral and linear composite grooves are made on the surface of the workpiece, reducing production costs by 60%.

[0026] 2. The heat pipe with grooves is equipped with a lifting block. The hand wheel rotates to drive the adjusting screw to rotate.

[0027] 3. The heat pipe with its own groove is equipped with a water tank. The laser welding machine is used to weld the connection parts of the workpiece. The welding parts of the workpiece are then leveled by the leveling blade. After that, the leveled workpiece enters the water tank. The cooling water in the water tank is sprayed out from the water nozzle by the water pump in the water tank to cool the welding parts of the workpiece.

[0028] 4. The heat pipe with its own groove is provided with a cutting guide groove and a grinding guide groove. The rotation of the toothed disc drives the rotation of the cutting guide groove. The rotation of the cutting guide groove drives the first telescopic slider to slide along the limit groove of the outer wall of the fixed disc through the cutting guide post. The sliding of the first telescopic slider drives the cutting machine to cut the workpiece. Then, the pneumatic push rod pushes the slide in the opposite direction to make the toothed disc rotate in the opposite direction. The reverse rotation of the toothed disc drives the rotation of the grinding guide groove. The rotation of the grinding guide groove drives the second telescopic slider to slide along the limit groove of the outer wall of the fixed disc through the grinding guide post. The sliding of the second telescopic slider drives the grinder to grind and deburr the cross-section of the workpiece after cutting, thereby realizing the cutting and deburring operation of the workpiece.

[0029] 5. The heat pipe with its own groove is provided with a rotating ratchet. The rotating guide column rotates through the rotating guide groove to drive the rotating ratchet to rotate. At the same time, the rotating disk rotates to drive the limit disk to fit with the limit guide groove, so as to realize the stable intermittent rotation of the rotating ratchet.

[0056] This embodiment also provides a method for preparing a heat pipe material with a groove, using the above device, and the method includes the following steps:

[0057] S1. First, the staff installs the workpiece 16 on the loading roller 18. Then, the active roller 1901 works to continuously feed the workpiece 16. Next, the staff adjusts the distance between the smooth roller 1904 and the rolling roller 1908 according to the thickness of the workpiece 16. The staff rotates the handwheel 1906, which drives the adjusting screw 1905 to rotate. The adjusting screw 1905 rotates through the lifting block 1907 to drive the rolling roller 1908 and the smooth roller 1904 to move relative to each other, thereby achieving the rolling operation for workpieces 16 of different thicknesses and preventing the stripes on the workpiece 16 from being too shallow or too deep.

[0058] S2. Next, the workpiece 16 is subjected to a rolling and texturing operation. The workpiece 16 is flattened by a leveling roller 1902. Then, it is rolled by a smooth roller 1904 and a rolling roller 1908 to form a striped top surface of the workpiece 16. Then, a laser texturing machine 1909 is used to texturize the workpiece 16 to form grooves on the top surface of the workpiece 16, forming a capillary structure. The capillary structure facilitates the flow of the working medium. If a drop of water is dropped on a smooth surface, the water will gather and not flow. However, if it is dropped on a capillary structure surface, the water will quickly flow to the surrounding area. The workpiece 16 is processed by the combination of the rolling roller 1908 and the laser texturing machine 1909, and spiral and linear composite grooves are formed on the surface of the workpiece 16, reducing the production cost by 60%.

[0059] S3. Then, the plate-shaped workpiece 16 is subjected to a tubular forming operation. The workpiece 16 passes through five sets of forming rollers 2001 in sequence. The five sets of forming rollers 2001 curl the workpiece 16 to achieve the tubular forming operation of the workpiece 16.

[0060] S4. Next, a welding cooling operation is performed on the connection portion of the workpiece 16. The laser welding machine 2101 is operated to weld the connection portion of the workpiece 16. The leveling blade 2102 then performs a leveling operation on the weld portion of the workpiece 16. The leveled workpiece 16 then enters the water tank 2103. The cooling water in the water tank 2103 is sprayed out of the water nozzle 2104 by a water pump in the water tank 2103 to cool the weld portion of the workpiece 16.

[0061] S5. Next, the workpiece 16 is fed and cut. The servo motor 2201 drives the feeding screw 2202 to rotate. The feeding screw 2202 rotates and drives the cutting frame 1 to slide along the top of the cutting feeding frame 22 at the same speed as the workpiece 16 through the connecting slider 2203, so that the cutting frame 1 and the workpiece 16 are in a relatively static state. At the same time, the pneumatic push rod 2 drives the sliding tooth plate 4 at the top of the slide 3 to slide. The sliding of the sliding tooth plate 4 drives the toothed disc 5 to rotate. The rotation of the toothed disc 5 drives the cutting guide groove 6 to rotate. The cutting guide groove 6 rotates and drives the cutting guide column 7 to rotate. The first telescopic slide 10 slides along the limit groove 9 of the outer wall of the fixed disk 8. The sliding of the first telescopic slide 10 drives the cutting machine 11 to cut the workpiece 16. Then, the pneumatic push rod 2 pushes the slide plate 3 in the opposite direction to make the gear plate 5 rotate in the opposite direction. The reverse rotation of the gear plate 5 drives the grinding guide groove 12 to rotate. The rotation of the grinding guide groove 12 drives the second telescopic slide 14 to slide along the limit groove 9 of the outer wall of the fixed disk 8 through the grinding guide column 13. The sliding of the second telescopic slide 14 drives the grinder 15 to grind and deburr the cross-section of the workpiece 16 after cutting, thereby realizing the feeding and cutting operation of the workpiece 16.

[0062] S6. Finally, the workpieces 16 are stacked in an orderly manner. The positioning motor 2303 drives the rotating guide post 2305 at the top of the rotating disk 2304 to rotate. The rotating guide post 2305 rotates and drives the rotating ratchet 2306 to rotate through the rotating guide groove 2307. At the same time, the rotating disk 2304 rotates and drives the limiting disk 2309 to fit with the limiting guide groove 2308, so as to realize the stable intermittent rotation of the rotating ratchet 2306. The rotating ratchet 2306 rotates and drives the stacking rack 2312 to slide intermittently along the top of the positioning frame 2302 through the intermittent gear 2310 and the positioning tooth plate 2311. Then, the hydraulic push rod 2301 works to lift the stacking rack 2312 at the top of the positioning frame 2302, so as to realize the orderly stacking operation of the workpieces 16, so as to avoid the chaotic stacking of the workpieces 16 during stacking, which causes the surface quality of the workpieces 16 to be damaged.

[0064] Next, the workpiece 16 is subjected to a rolling and texturing operation. The workpiece 16 is flattened by a leveling roller 1902. Then, it is rolled by a smooth roller 1904 and a rolling roller 1908 to form a striped top surface of the workpiece 16. Then, a laser texturing machine 1909 is used to texturize the workpiece 16 to form grooves on the top surface of the workpiece 16, forming a capillary structure. The capillary structure facilitates the flow of the working medium. If a drop of water is dropped on a smooth surface, the water will gather and not flow.

[0066] Next, a welding cooling operation is performed on the connection portion of the workpiece 16. The laser welding machine 2101 is operated to weld the connection portion of the workpiece 16. The leveling blade 2102 then performs a leveling operation on the weld portion of the workpiece 16. The leveled workpiece 16 then enters the water tank 2103. The cooling water in the water tank 2103 is sprayed out of the water nozzle 2104 by the water pump in the water tank 2103 to cool the weld portion of the workpiece 16.

[0067] Next, the workpiece 16 is fed and cut. The servo motor 2201 drives the feeding screw 2202 to rotate.

At the same time, the pneumatic push rod 2 works to drive the sliding tooth plate 4 at the top of the slide plate 3 to slide. The sliding of the sliding tooth plate 4 drives the tooth disc 5 to rotate. The rotation of the tooth disc 5 drives the cutting guide groove 6 to rotate. The cutting guide groove 6 rotates and drives the cutting guide column 7 to rotate. A telescopic slide 10 slides along the limit groove 9 on the outer wall of the fixed disk 8. The sliding of the first telescopic slide 10 drives the cutting machine 11 to cut the workpiece 16. Then, the pneumatic push rod 2 pushes the slide 3 in the opposite direction to make the gear plate 5 rotate in the opposite direction. The reverse rotation of the gear plate 5 drives the grinding guide groove 12 to rotate. The rotation of the grinding guide groove 12 drives the second telescopic slide 14 to slide along the limit groove 9 on the outer wall of the fixed disk 8 through the grinding guide column 13. The sliding of the second telescopic slide 14 drives the grinder 15 to grind and deburr the cross-section of the workpiece 16 after cutting, thereby realizing the feeding and cutting operation of the workpiece 16.

[0068] Finally, the processed workpieces 16 are stacked in an orderly manner. The positioning motor 2303 drives the rotating guide post 2305 at the top of the rotating disk 2304 to rotate. The rotating guide post 2305 rotates and drives the rotating ratchet 2306 to rotate through the rotating guide groove 2307.

The grinding guide groove (12) rotates to drive the second telescopic slide (14) to slide along the limiting groove (9) on the outer wall of the fixed disk (8) through the grinding guide column (13). The second telescopic slide (14) slides to drive the grinding machine (15) to grind and deburr the cross section of the workpiece (16) after cutting, thereby realizing the feeding and cutting operation of the workpiece (16); S6. Finally, the workpieces (16) are stacked in an orderly manner. The positioning motor (2303) drives the rotating guide post (2305) at the top of the rotating disk (2304) to rotate. The rotating guide post (2305) rotates through the rotating guide groove (2307) to drive the rotating ratchet (2306) to rotate. At the same time, the rotating disk (2304) rotates to drive the limiting disk (2309) to fit with the limiting guide groove (2308), thereby achieving stable intermittent rotation of the rotating ratchet (2306). The rotating ratchet (2306) rotates through the intermittent gear (2310) and the positioning tooth plate (2311) to drive the stacking rack (2312) to slide intermittently along the top of the positioning frame (2302). Then, the hydraulic push rod (2301) works to lift and lower the stacking rack (2312) at the top of the positioning frame (2302), thereby achieving an orderly stacking operation of the processed workpieces (16) and avoiding the chaotic stacking of the processed workpieces (16) during stacking, which may cause damage to the surface quality of the processed workpieces (16).
