Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat sink porous flat tube processing, and particularly relates to a heat sink porous flat tube processing and forming device. BACKGROUND

[0002] The heat sink porous flat tube is a key heat exchange component in the fields of refrigeration, air conditioning, automobiles and the like, which is usually made of aluminum or copper alloy and has multiple micro-channels inside to increase the heat dissipation area.

[0003] In the prior art, the heat sink porous flat tube needs to be cut into a certain length during processing. During the cutting process, the cutter generates high temperature when rubbing against the workpiece, which causes plastic deformation of the material instead of complete shearing, and a large amount of burrs and flash is easily generated at the edge of the cutting section. The burrs block the precise flow channels inside the flat tube, seriously affecting the heat dissipation efficiency and service life of the heat sink, and even causing system failure. In order to remove the burrs, a separate polishing, polishing or deburring secondary processing link needs to be added after the cutting process, which not only greatly reduces the production efficiency, but also increases the labor and equipment costs, and may cause product damage or deformation during handling and secondary clamping. The traditional cutting and deburring separation operation mode is difficult to integrate into an automatic production line, which becomes a bottleneck restricting the improvement of production efficiency.

[0017] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the concept of the present application, so the present application is not limited to the specific implementations disclosed below.

[0018] With reference to Figures 1-8 A porous flat tube machining and forming equipment for a heat sink includes a machine tool 1 and four mounting boxes 8, the upper end of the machine tool 1 is fixedly connected with a machining table 2, the upper end of the machining table 2 is provided with a mounting groove 3, the inner bottom of the machine tool 1 is fixedly connected with a mounting frame 4, the side wall of the mounting frame 4 is provided with a sliding groove 5, the inner wall of the sliding groove 5 is slidably connected with a cutting frame 6, and the cutting frame 6 is provided with a cutting machine 7; The grinding mechanism includes an H-shaped block 9 sealingly and slidably connected to the inner wall of the mounting box 8, the side wall of the H-shaped block 9 is fixedly connected with a connecting plate 10, the other end of the connecting plate 10 penetrates through the side wall of the mounting box 8 and is provided, the upper end of the connecting plate 10 is rotatably connected with a rotating shaft 11, the upper end of the rotating shaft 11 is fixedly connected with a grinding wheel 12, two of the mounting boxes 8 are symmetrically and fixedly connected to the inner wall of the mounting groove 3, the upper end of the other two mounting boxes 8 is fixedly connected with a sliding cylinder 13, the inner wall of the sliding cylinder 13 is sealingly and slidably connected with a sliding plug 14, the upper end of the sliding plug 14 is fixedly connected with a fixed rod 15, and the other end of the fixed rod 15 is fixedly connected with the side wall of the cutting frame 6.

[0019] The grinding mechanism further includes a first spring 16 sleeved on the side wall of the fixed rod 15, the two ends of the first spring 16 are fixedly connected with the inner top of the sliding cylinder 13 and the upper end of the sliding plug 14 respectively, and the sliding cylinder 13 communicates with the mounting box 8 through a first communication pipe 17.

[0020] The side wall of two of the mounting boxes 8 is fixedly connected with a pressing plate 18, the upper end of the connecting plate 10 is fixedly connected with a motor 19, and the output end of the motor 19 penetrates through the upper end of the connecting plate 10 and is fixedly connected with the rotating shaft 11.

[0021] It should be noted that when the pressing plate 18 moves downward to be attached to the upper end of the porous flat tube, the pressing plate 18 cannot continue to move downward at this time, and the cutting frame 6 continues to move downward to give the pressing plate 18 pressure, so as to press the porous flat tube, avoiding the position of the porous flat tube from being deviated during cutting, causing the cutting position to be deviated.

[0022] As Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, further, when the lower end of the cutting tool in the cutting machine 7 is in contact with the upper end of the porous flat tube, at this time, the two grinding wheels 12 located above will also be in contact with the upper end of the porous flat tube, and as the cutting machine 7 continues to move downward, the cutting process will begin. During the cutting process, as the cutting frame 6 feeds downward to drive the cutting machine 7 to continue to move downward, the fixed rod 15 will slide downward to drive the sliding plug 14 to seal and slide downward in the sliding cylinder 13. At this time, part of the cutting fluid in the sliding cylinder 13 will enter the installation box 8 through the first communication pipe 17, thereby pushing the H-shaped block 9 to move, driving the connecting plate 10 to move, thereby driving the grinding wheel 12 and the motor 19 to translate, and synchronously driving the motor 19. The motor 19 drives the rotating shaft 11 to rotate, thereby driving the grinding wheel 12 to rotate. Therefore, during the cutting of the porous flat tube, the grinding wheel 12 will rotate during translation, thereby grinding the burrs generated during cutting of the porous flat tube, and automatically removing the burrs generated during cutting of the porous flat tube.

[0023] The pressing plate 18 is provided with a cooling mechanism, which comprises a liquid spraying head 21 fixedly connected to the upper end of the pressing plate 18. The sliding cylinder 13 is in communication with the liquid spraying head 21 through a one-way liquid supply pipe 22. The one-way liquid supply pipe 22 only allows the cutting fluid in the sliding cylinder 13 to enter the liquid spraying head 21. A one-way liquid inlet pipe 23 is fixedly connected to the inner wall of the sliding cylinder 13. The other end of the one-way liquid inlet pipe 23 is in communication with an external container storing cutting fluid. The one-way liquid inlet pipe 23 only allows external cutting fluid to enter the sliding cylinder 13.

[0024] As shown in Figure 4 , Figure 5 and Figure 7 , further, during the cutting process, as the sliding plug 14 seals and slides downward, part of the cutting fluid will enter the liquid spraying head 21 through the one-way liquid supply pipe 22, and then the cutting fluid will be sprayed out of the liquid spraying head 21 to the cutting tool of the cutting machine 7 and the cutting position of the porous flat tube, thereby playing a lubricating and cooling effect, which can effectively protect the cutting tool and reduce the generation of burrs.

[0025] It is worth mentioning that the supply of cutting fluid is synchronized with the start and end of cutting, which can reduce the waste of cutting fluid.

[0026] The upper end of the mounting frame 4 is fixedly connected with a hydraulic oil cylinder 24. The movable end of the hydraulic oil cylinder 24 penetrates the top of the sliding groove 5 and is fixedly connected with the cutting frame 6.

[0027] The mounting frame 4 is provided with an adjusting mechanism, which comprises two adjusting cylinders 25 fixedly connected to the top of the mounting frame 4. The inner walls of the two adjusting cylinders 25 are sealingly and slidably connected with sliding plates 26. The lower end of each sliding plate 26 is fixedly connected with a connecting rod 27. The lower end of each connecting rod 27 penetrates the lower end of the adjusting cylinder 25 and is fixedly connected with the sliding cylinder 13.

[0028] The adjusting mechanism further comprises two adjusting plates 29 symmetrically and sealingly slidingly connected to the inner wall of the mounting box 8, two sealing blocks 28 symmetrically and sealingly slidingly connected to the inner wall of the H-shaped block 9, and a second spring 30 fixedly connected between the inner wall of the H-shaped block 9 and the sealing blocks 28. Under the action of the second spring 30, the side wall of the sealing block 28 can be kept in close contact with the adjusting plate 29, thereby keeping the seal, and the sealing block 28 can also be reset under the action of the second spring 30. The mounting box 8 is communicated with the adjusting cylinder 25 through the second communication pipe 20.

[0029] It should be noted that the contact surfaces of the two sealing blocks 28 and the adjusting plates 29 are all sealing sliding, and the upper end and the lower end of the sealing block 28 are both sealingly slidingly connected to the inner wall of the mounting box 8. The first communication pipe 17 is communicated with the space between the two adjusting plates 29 in the mounting box 8, and the second communication pipe 20 is communicated with the side space of the two adjusting plates 29. The first communication pipe 17, the second communication pipe 20, the one-way liquid supply pipe 22, and the one-way liquid inlet pipe 23 are all made of a hose.

[0030] As shown in Figure 4 , Figure 5 , Figure 6 and Figure 8 , further, since the downward feeding stroke of the hydraulic cylinder 24 is fixed each time, for the thinner porous flat tube, when the cutting machine 7 moves downward to the maximum position, less cutting fluid will be squeezed into the mounting box 8, thereby making the sliding stroke of the H-shaped block 9 shorter, which may cause the sliding stroke of the grinding wheel 12 to be insufficient, thereby failing to perform burr grinding on the entire cutting width of the porous flat tube. Therefore, when the cutting frame 6 moves downward to the position where the pressing plate 18 abuts against the upper end of the porous flat tube, the sliding cylinder 13 will drive the connecting rod 27 to slide downward, thereby driving the sliding plate 26 to sealingly slide downward. At this time, the air in the adjusting cylinder 25 will be squeezed into the mounting box 8 through the second communication pipe 20, thereby causing the two adjusting plates 29 to slide towards each other. The sealing blocks 28 will be squeezed to slide towards the inside of the H-shaped block 9, thereby narrowing the flow channel of the cutting fluid in the mounting box 8. For the thinner porous flat tube, more air will be squeezed into the mounting box 8 before cutting, thereby making the distance between the two adjusting plates 29 smaller, and thereby the flow channel of the cutting fluid in the mounting box 8 will be narrower. For the same amount of cutting fluid pumped in, the stroke of the H-shaped block 9 can be increased virtually. For less cutting fluid pumped in, but the flow channel of the cutting fluid is narrower, the stroke of the H-shaped block 9 can be kept basically unchanged. Therefore, when cutting the porous flat tubes with different thicknesses, the grinding wheel 12 can keep enough stroke to remove the burrs of the cutting position of the porous flat tube, thereby making the entire device have a wider application range.

[0031] It is worth mentioning that the thicker the porous flat pipe is, the more heat it generates during cutting, and the thicker the porous flat pipe is, the more cutting fluid it supplies simultaneously to ensure the cooling effect, so that the supply amount of cutting fluid can be automatically adjusted according to the porous flat pipe of different thickness, and the waste of cutting fluid is further reduced.

[0032] In the application, the heat sink porous flat pipe is placed on the machining table 2, and the external conveying device can feed the porous flat pipe, then the cutting machine 7 is started, and then the hydraulic cylinder 24 is driven to elongate, driving the cutting frame 6 to move downward, thereby driving the cutting machine 7 to move downward, starting to cut the porous flat pipe, when the cutting frame 6 moves downward, the pressing plate 18 will be driven to move downward synchronously, when the pressing plate 18 moves downward to the upper end of the porous flat pipe, the pressing plate 18 cannot continue to move downward, and the cutting frame 6 continues to move downward to press the porous flat pipe, avoiding the position deviation of the porous flat pipe during cutting, causing the cutting position deviation.

[0033] When the lower end of the cutting tool in the cutting machine 7 contacts the upper end of the porous flat pipe, the two grinding wheels 12 above will also contact the upper end of the porous flat pipe, and as the cutting machine 7 continues to move downward, the cutting process of the porous flat pipe will begin, during the cutting process, when the cutting frame 6 feeds downward to drive the cutting machine 7 to continuously move downward, the fixed rod 15 will slide downward to drive the sliding plug 14 to seal sliding downward in the sliding cylinder 13, at this time, part of the cutting fluid in the sliding cylinder 13 will enter the installation box 8 through the first communication pipe 17, thereby driving the H-shaped block 9 to move, driving the connecting plate 10 to move, thereby driving the grinding wheel 12 and the motor 19 to translate, and synchronously driving the motor 19, the motor 19 drives the rotating shaft 11 to rotate, thereby driving the grinding wheel 12 to rotate, so that during the cutting of the porous flat pipe, the grinding wheel 12 will translate and rotate, thereby grinding the burrs and flash generated at the cutting position of the porous flat pipe, and automatically removing the burrs and flash generated during cutting of the porous flat pipe.

[0034] During the cutting process, when the sliding plug 14 seals and slides downward, part of the cutting fluid will enter the liquid injection head 21 through the one-way liquid supply pipe 22, and then the cutting fluid will be sprayed out through the liquid injection head 21, sprayed onto the cutting tool of the cutting machine 7 and the cutting position of the porous flat pipe, which can play a lubricating and cooling effect, and can effectively protect the cutting tool and reduce the generation of burrs and flash.

[0035] After cutting, the hydraulic cylinder 24 will be shortened to drive the cutting frame 6 and the cutting machine 7 to move upward and reset, at this time the sliding plug 14 will be upwardly sealed sliding, the external cutting fluid is pumped into the sliding cylinder 13 for storage and standby through the one-way liquid inlet pipe 23, and the cutting fluid in the mounting box 8 will also be pumped back into the sliding cylinder 13 through the first communication pipe 17, so that the H-shaped block 9 drives the connecting plate 10 to slide and reset, and drives the grinding wheel 12 to move and reset, so that the grinding wheel 12 reciprocatingly moves back and forth to remove the burr and flash in the process of cutting.

[0036] Since the hydraulic cylinder 24 drives the cutting machine 7 to move downward with a fixed stroke each time, for the thinner porous flat tube, when the cutting machine 7 moves to the maximum position, less cutting fluid will be squeezed into the mounting box 8, and the sliding stroke of the H-shaped block 9 will be shorter, which may cause the insufficient reciprocating sliding stroke of the grinding wheel 12, so that the burr of the entire cutting width of the porous flat tube cannot be ground, therefore, when the cutting frame 6 moves downward to the position where the pressing plate 18 abuts against the upper end of the porous flat tube, the sliding cylinder 13 drives the connecting rod 27 to slide downward, thereby driving the sliding plate 26 to slide downward and seal, at this time the air in the adjusting cylinder 25 is squeezed into the mounting box 8 through the second communication pipe 20, so as to drive the two adjusting plates 29 to slide close to each other, the sealing block 28 is squeezed to slide to the inside of the H-shaped block 9, so that the flow channel of the cutting fluid in the mounting box 8 is narrowed, for the thinner porous flat tube, more air will be squeezed into the mounting box 8 before cutting, so that the distance between the two adjusting plates 29 is smaller, and the flow channel of the cutting fluid in the mounting box 8 is narrower, and for the same amount of cutting fluid pumped in, the stroke of the H-shaped block 9 can be increased, and for less cutting fluid pumped in, but the flow channel of the cutting fluid is narrower, so that the stroke of the H-shaped block 9 can be kept basically unchanged, therefore, for the cutting of porous flat tubes with different thicknesses, the grinding wheel 12 can keep enough stroke to remove the burr of the cutting part of the porous flat tube, so that the application range of the entire device is wider.

[0037] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
