Description

Technical Field

[0001] The invention relates to the technical field of battery pack water-cooling plate processing, and in particular to a grooving and chamfering device for a heat dissipation water-cooling plate. Background Art

[0002] The battery water cooling plate is a device that uses water cooling technology to control the battery temperature. The battery water cooling plate uses water as a cooling medium, and uses the high specific heat capacity and excellent thermal conductivity of water to take away the heat generated by the battery during operation, thereby keeping the battery within a suitable temperature range. It has complex cooling channels inside for the flow of cooling water. These channels need to be processed by grooving. Since the edges of the notches of the water cooling plate are right-angled, tip discharge is prone to occur. After spraying, the notches or groove edges are sharp, so chamfering is also required.

[0003] There are two common ways to chamfer the existing water-cooled plates. One is to cut and mill the grooves, mill the grooves on the aluminum plate, and then chamfer the grooves. The other is to directly stamp them through a special mold. When using stamping molds, suitable lubricants are required to reduce the friction between the mold and the material, reduce energy consumption and mold wear. Generally, the lubricant is directly brushed on the workpiece and the mold through a brushing device.

[0004] However, the existing water-cooled plate slotting and chamfering has the following shortcomings when processed by stamping forming equipment: during stamping and forming, the lubricant used is generally manually brushed on the workpiece and the mold through a brushing tool. In order to ensure the lubrication effect, the lubricant is generally excessively brushed, that is, too much lubricant is easily accumulated on the mold and the workpiece, which needs to be processed later. Since the workpiece is easy to pick up and put, it is easy to clean, but the mold, especially the fixed mold, is generally fixedly installed on the support. After the lubricant accumulates on the fixed mold, it is not convenient to process, and in the stamping process, the applied lubricant is constantly consumed because it will adhere to the workpiece and be carried away by the unloaded workpiece. Therefore, it is necessary to continuously replenish the lubricant according to the situation manually, but the amount of consumption each time is not certain, so the amount of lubricant that needs to be replenished is difficult to grasp manually, resulting in inconvenient use of the lubricant. Summary of the invention

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention cooperates with a special movable die and a fixed die for stamping, so as to facilitate punching out a groove body with a round chamfer on a plate-shaped aluminum original part, which is convenient for use as a water-cooling plate. At the same time, when the hydraulic telescopic rod drives the movable die to move and stamp, the main piston plate arranged in linkage with the telescopic end of the hydraulic telescopic rod moves along the main piston cylinder, and squeezes a certain amount of lubricating liquid into the shaping groove of the fixed die, which is convenient for lubrication.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 7 As shown, a slotting and chamfering device for a heat dissipation water cooling plate, the heat dissipation water cooling plate is a heat dissipation cooling element used in a battery pack, generally a plate-shaped aluminum original part, the slotting and chamfering device is used to process the flow channel on the heat dissipation water cooling plate, the slotting is used to process the flow channel body, and then the opening edge position of the flow channel body is chamfered to avoid tip discharge and reduce stress concentration; the device relies on a customized stamping die to stamp and form on the original plate-shaped aluminum part, completing slotting and chamfering at one time;

[0034] The device comprises a support base 1, a fixed die 3 and a movable die 11. The fixed die 3 is fixedly mounted on the support base 1, and the movable die 11 is matched and arranged on the fixed die 3. Hydraulic telescopic rods 2 for driving the movable die 11 to rise and fall are fixedly mounted on both sides of the support base 1. The aluminum plate is placed on the fixed die 3, and driven by the hydraulic telescopic rods 2, so that the movable die 11 is stamped onto the fixed die 3.

[0035] Among them, the movable mold 11 is provided with raised shaping parts for stamping the flow channel, and each raised shaping part is provided with rounded grooves on both sides, and the fixed mold 3 is provided with shaping grooves matching with the raised shaping parts, and each shaping groove is provided with rounded edges matching with the rounded grooves on both sides of the notch, as shown in the specific Figure 6As shown, during stamping, the plate-shaped aluminum original is placed on the fixed die 3, and then the aluminum plate is stamped by the movable die 11, and the protruding shaping part squeezes the aluminum plate to deform and embed into the shaping groove to achieve slotting, and at the same time, the matching rounded groove and rounded edge realize the rounded shaping of the notch edge of each slot;

[0036] The device also includes a piston-type lubricating liquid delivery mechanism and a lubricating liquid brushing mechanism for brushing lubricating oil on the surface of the plate-shaped aluminum original of the water-cooling plate; a linkage driving mechanism is provided between the piston-type lubricating liquid delivery mechanism and the telescopic end of the hydraulic telescopic rod 2. When the hydraulic telescopic rod 2 is retracted, the telescopic end of the hydraulic telescopic rod 2 drives the piston-type lubricating liquid delivery mechanism through the linkage driving mechanism to inject lubricating liquid into the fixed mold 3;

[0037] The lubricating liquid brushing mechanism is slidably arranged on the upper surface of the fixed mold 3, and through reciprocating sliding, it is convenient to brush the lubricating liquid on the upper surface of the plate-like aluminum original placed on the fixed mold 3; in this way, when the movable mold 11 is lowered and stamped onto the fixed mold 3, there is lubricating liquid on the upper and lower surfaces of the plate-like aluminum original, which is convenient for lubrication and reduces wear, and the lubricating liquid can also be used for cooling.

[0038] It should be noted that clamping mechanisms can be set on both sides of the movable mold 11. After the movable mold 11 stamps the plate-shaped aluminum original on the fixed mold 3, the clamping mechanism clamps the edge of the plate and then lifts it away from the fixed mold 3.

[0039] In some specific embodiments, in combination Figure 1 and Figure 2 As shown, the piston-type lubricating fluid delivery mechanism includes a main piston cylinder 12, a main piston plate 13 and a lubricating fluid supply mechanism. The support base 1 is a U-shaped structure with an opening downward. The main piston cylinder 12 is fixedly arranged on the inner top of the support base 1, and the main piston plate 13 is slidably arranged in the main piston cylinder 12, and the main piston plate 13 is arranged in cooperation with the telescopic end of the hydraulic telescopic rod 2 through a linkage driving mechanism. There is a certain distance between the initial position of the main piston plate 13 and the inner top of the main piston cylinder 12, that is, there is a certain space. At this time, the upper space of the main piston plate 13 is filled with lubricating fluid, that is, the upper space of the main piston plate 13 is the lubricating fluid delivery space, and an elastic limiting mechanism is arranged between the main piston plate 13 and the support base 1. A plurality of conduits 24 connected to the molding grooves of the fixed mold 3 are distributed on the top of the main piston cylinder 12, and the lubricating fluid supply mechanism is used to supply lubricating fluid to the main piston cylinder 12.

[0040] Among them, there are two groups of lubricating liquid replenishing mechanisms, which are distributed on both sides of the support base 1. The lubricating liquid replenishing mechanism includes a storage cylinder 8, a suction tube 9 and a one-way liquid inlet valve 26. The storage cylinder 8 is fixedly arranged relative to the support base 1. One end of the suction tube 9 is inserted into the storage cylinder 8, and the other end is connected to the top of the main piston cylinder 12 through the one-way liquid inlet valve 26. The one-way liquid inlet valve 26 controls the lubricating liquid to enter the main piston cylinder 12 only through the suction tube 9 and cannot flow in the opposite direction.

[0041] It should be noted that a feed control valve component 27 is fixedly installed on the suction tube 9 near the one-way liquid inlet valve 26. When the main piston plate 13 is in the initial position, there is no lubricating liquid in the main piston cylinder 12 and there is no lubricating liquid in the storage cylinder 8. At this time, the feed control valve component 27 can be opened, and the lubricating liquid is injected into the suction tube 9 through the feed control valve component 27. The lubricating liquid can then flow into the main piston cylinder 12 and the storage cylinder 8. The main piston cylinder 12 and the storage cylinder 8 can be set to be transparent, which is convenient for observing the injection amount.

[0042] When the hydraulic telescopic rod 2 contracts, so that the movable die 11 is punched onto the fixed die 3, and the plate-shaped aluminum original placed on the fixed die 3 is punched, the telescopic end of the hydraulic telescopic rod 2 is linked to the main piston plate 13 to move upward along the main piston cylinder 12. At this time, the main piston plate 13 squeezes the lubricating fluid in the main piston cylinder 12 and injects it into each shaping groove of the fixed die 3 through the distributed conduits 24. When the plate-shaped aluminum original is stamped and deformed and embedded in the shaping groove, the lubricating fluid injected into the shaping groove is squeezed, which facilitates the lubricating fluid to overflow and spread, and facilitates lubrication of the contact position between the fixed die 3 and the plate-shaped aluminum original. In this process, the elastic limiter generates a rebound force. When the hydraulic telescopic rod 2 is extended, the movable die 11 is pressed onto the fixed die 3, and the plate-shaped aluminum original is pressed. The main piston plate 13 is long, so that when the movable mold 11 rises, the main piston plate 13 slides down and resets along the main piston cylinder 12 under the action of the rebound force of the elastic limiter. During this process, the main piston cylinder 12 sucks the lubricating liquid in the molding groove of the fixed mold 3 through the conduit 24, which is convenient for recovering part of the lubricating liquid. Obviously, there will be a part of the lubricating liquid sticking to the side wall of the fixed mold 3 and the water-cooled plate after stamping, so it cannot be fully recovered. However, when the main piston plate 13 slides back and resets, it sucks the lubricating liquid from the storage cylinder 8 through the one-way liquid inlet valve 26 and the suction pipe 9 to replenish it in the main piston cylinder 12, ensuring that after each reset of the main piston plate 13, a fixed amount of lubricating liquid is stored in the main piston cylinder 12 for convenient use.

[0043] It should also be explained here that the piston structure is provided to ensure that a sufficient amount of lubricating liquid is injected into the fixed mold 3 each time for sufficient lubrication and to absorb the heat generated by mold friction and deformation of the plate-like aluminum original. Since the fixed mold 3 is fixed on the support base 1, it is necessary to ensure that the position is fixed during the stamping process. Each time the lubricating liquid is injected to complete the stamping operation, the lubricating liquid accumulated in the fixed mold 3 is not convenient to handle, and the amount left for direct use in the next stamping may not be enough, because there is also adhesion on the workpiece, which will take away part of the lubricating liquid, so a certain amount must be replenished. Therefore, the present application directly sets a piston structure to suck away the accumulated lubricating liquid when resetting, without manual processing, and the lubricating liquid can still be quantitatively injected next time. Even if too much lubricating liquid is brushed on the surface of the plate-like aluminum original, since the plate-like aluminum original can be easily removed after stamping, it can be manually dumped.

[0044] In some specific embodiments, the elastic limiter includes a lifting guide rod 14 and a guide sleeve 18. The guide sleeve 18 is fixedly connected to the support base 1 through the rod body and is located in the middle position of the U-shaped support base 1. The lifting guide rod 14 slides through the guide sleeve 18, and a stretchable connecting spring 19 is connected between the lifting guide rod 14 and the guide sleeve 18. The top of the lifting guide rod 14 is fixedly connected to the main piston plate 13.

[0045] In some specific embodiments, in combination Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the linkage drive mechanism includes a support frame 17, a linkage ring 29, an extension plate 10 and a push rod 7. The support frame 17 is fixedly connected to the inner side of the support base 1, the linkage ring 29 surrounds the outside of the lifting guide rod 14, and an elastic telescopic rod 28 is connected between the linkage ring 29 and the support frame 17. The elastic telescopic rod 28 includes a telescopic rod and a spring connected to both ends of the telescopic rod. A flip pushing mechanism is provided between the linkage ring 29 and the lifting guide rod 14. The extension plate 10 is fixedly connected to the linkage ring 29, and the extension plate 10 extends from the support base 1. The push rod 7 is fixedly connected to the telescopic end of the hydraulic telescopic rod 2, and the push rod 7 is aligned with the extension plate 10.

[0046] The linkage ring 29 and the extension plate 10 are an integrated structure.

[0047] Among them, the flipping and pushing mechanism includes a rotating rod 16 and a baffle 15, and the support frame 17 is fixedly provided with an axis frame in pairs. The rotating rod 16 is rotatably connected to the axis frame through a rotating shaft, and the rotating rod 16 is tilted and matched in the inner circle of the linkage ring 29. The baffle 15 is fixedly connected to the lifting guide rod 14, and the end of the rotating rod 16 away from the linkage ring 29 is in contact with the bottom of the baffle 15.

[0048] When the hydraulic telescopic rod 2 contracts and drives the movable die 11 to descend and approach the plate-like aluminum original, before it contacts, the push rod 7 connected to the telescopic end of the hydraulic telescopic rod 2 just starts to push the extension plate 10, and the extension plate 10 drives the linkage ring 29 to compress the elastic telescopic rod 28 to shrink and descend. At this time, the linkage ring 29 squeezes the rotating rod 16, causing the rotating rod 16 to deflect, and the end of the rotating rod 16 away from the linkage ring 29 rotates to push the baffle 15, so that the baffle 15 drives the lifting guide rod 14 to rise, thereby realizing the lifting of the main piston plate 13, and when the movable die 11 contacts the plate-like aluminum original for stamping, the linkage ring 29 has squeezed the rotating rod 16 to a vertical position, and the linkage ring 29 descends along the rotating rod 16.

[0049] In some specific implementation schemes, since the main piston plate 13 will be reset during the process of the main piston cylinder 12 sucking a certain amount of lubricating fluid from the fixed mold 3 through the conduit 24, and this part of the lubricating fluid will absorb the heat generated by the deformation and friction during the stamping process of the plate-shaped aluminum original, and the sucked back lubricating fluid will be squeezed out again, in order to avoid the temperature increase of the lubricating fluid that is repeatedly used during the continuous stamping operation, a set of circulating cooling mechanism is set, and the circulating cooling mechanism includes a sub-piston cylinder 22, a sub-piston plate 23, a heat exchange circulation pipe 20 and a refrigerator 21. The sub-piston cylinder 22 is fixedly arranged at the bottom of the support base 1, and the sub-piston plate 23 is slidably matched. In the secondary piston cylinder 22, the end of the lifting guide rod 14 away from the main piston plate 13 is fixedly connected to the secondary piston plate 23. When there is a certain space between the main piston plate 13 and the top of the main piston cylinder 12, the secondary piston plate 23 is at the bottom of the secondary piston cylinder 22. Conversely, when the main piston plate 13 rises, there is a certain space between the secondary piston plate 23 and the bottom of the secondary piston cylinder 22. The two ends of the heat exchange circulation pipe 20 are respectively fixedly connected to the two sides of the bottom of the secondary piston cylinder 22 to form a loop. One side of the bottom of the secondary piston cylinder 22 is fixedly provided with a first one-way valve connected to one end of the heat exchange circulation pipe 20, and the other side is fixedly provided with a second one-way valve connected to the other end of the heat exchange circulation pipe 20. One-way valve, the heat exchange circulation pipe 20 flows with heat exchangeable liquid, one of the first one-way valves allows the liquid to flow only from the auxiliary piston cylinder 22 to the heat exchange circulation pipe 20, and the other first one-way valve allows the liquid to flow only from the heat exchange circulation pipe 20 to the auxiliary piston cylinder 22. A plurality of spiral tube bodies 25 are distributed on the heat exchange circulation pipe 20, and each spiral tube body 25 is arranged in correspondence with the conduit 24, that is, the spiral tube body 25 is wound around the outside of the conduit 24, and the conduit 24 itself is also a heat exchange pipe fitting. The refrigerator 21 is connected in series with the heat exchange circulation pipe 20, and the refrigerator 21 here is a device for cooling the liquid flowing in the heat exchange circulation pipe 20 , which includes four major parts: compressor, condenser, throttling element and evaporator. The compressor is responsible for compressing low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas; then after the high-temperature and high-pressure refrigerant gas enters the condenser, it transfers heat to the surrounding environment through the heat exchange process, thereby condensing into low-temperature and high-pressure liquid; when the refrigerant liquid passes through the throttling element, due to the sudden reduction in pipe diameter or the precise adjustment of the electronic expansion valve, the pressure and temperature of the refrigerant liquid will decrease, becoming a low-temperature and low-pressure liquid; after the low-temperature and low-pressure refrigerant liquid enters the evaporator, it absorbs the heat of the flowing liquid in the pipeline through the heat exchange process, thereby evaporating into a low-temperature and low-pressure gas. In this process, the temperature of the flowing liquid in the pipeline will decrease, that is, the liquid in the heat exchange circulation pipe 20 will cool down.

[0050] When the lifting guide rod 14 descends, causing the main piston plate 13 to descend, the main piston cylinder 12 sucks the lubricating liquid in the fixed mold 3 through the conduit 24. At this time, the lubricating liquid absorbs heat, and when the lifting guide rod 14 descends, it also drives the secondary piston plate 23 to descend. The secondary piston plate 23 compresses the liquid in the secondary piston cylinder 22 and flows into the heat exchange circulation pipe 20 through the one-way valve on one side. Then the liquid flows along the heat exchange circulation pipe 20 through the spiral tube body 25, and realizes heat exchange with the lubricating liquid in the wound conduit 24, absorbing the heat absorbed by the lubricating liquid, so that the recovered lubricating liquid is cooled. When the lubricating liquid is transported to the fixed mold 3 again, the lubricating liquid can effectively absorb heat again to cool the fixed mold 3 and avoid thermal deformation.

[0051] In some specific embodiments, such as Figure 7 As shown, the lubricating liquid brushing mechanism includes an electric guide rail 4, a brushing member 6 and a liquid storage box 5. The electric guide rail 4 is fixedly connected to the supporting base 1 laterally and is at the edge position of one side of the supporting base 1, which can avoid affecting the lifting and lowering movement of the movable mold 11. The electric guide rail 4 is equipped with a sliding member that can move back and forth laterally. The brushing member 6 is slidably connected to the electric guide rail 4 through the sliding member. The liquid storage box 5 is fixedly arranged on one side of the top of the supporting base 1. The upper side of the liquid storage box 5 is an opening, and a certain amount of lubricating liquid is stored inside. The brushing member 6 is long and has a certain width. It can be bent and deformed. The original state is good. A part of the brushing member 6 is immersed in the liquid storage box 5 and can absorb a certain amount of lubricating liquid. When the plate-like aluminum original is placed on the fixed mold 3, the electric guide rail 4 is started, so that the electric guide rail 4 drives the brushing member 6 immersed in the liquid storage box 5 to move laterally, so that the brushing member 6 will brush a layer of lubricating liquid along the upper surface of the plate-like aluminum original, which is convenient for lubrication of subsequent stamping operations.

[0052] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0053] First, the plate-shaped aluminum original used for water-cooling plate processing is placed on the fixed mold 3, and then the electric guide rail 4 is started, so that the electric guide rail 4 drives the brushing member 6 immersed in the liquid storage box 5 to move horizontally, so that the brushing member 6 brushes a layer of lubricating liquid along the upper surface of the plate-shaped aluminum original, and then the hydraulic telescopic rod 2 is started to contract, and the hydraulic telescopic rod 2 drives the moving mold 11 to punch onto the fixed mold 3, and punches the plate-shaped aluminum original placed on the fixed mold 3;

[0054] When the telescopic end of the hydraulic telescopic rod 2 drives the mold 11 to descend and approach the plate-shaped aluminum original, before contacting, the push rod 7 connected to the telescopic end of the hydraulic telescopic rod 2 just starts to push the extension plate 10, and the extension plate 10 drives the linkage ring 29 to compress the elastic telescopic rod 28 to shrink and descend. At this time, the linkage ring 29 squeezes the rotating rod 16, causing the rotating rod 16 to deflect, and the end of the rotating rod 16 away from the linkage ring 29 rotates to push the baffle plate 15, so that the baffle plate 15 drives the lifting guide rod 14 to rise, and the main piston plate 13 is lifted;

[0055] The main piston plate 13 moves upward along the main piston cylinder 12. At this time, the main piston plate 13 squeezes the lubricating fluid in the main piston cylinder 12 and injects it into the various molding grooves of the fixed mold 3 through the distributed conduits 24. When the plate-shaped aluminum original is stamped and deformed and embedded in the molding groove, the lubricating fluid injected into the molding groove is squeezed to facilitate the lubricating fluid to overflow and spread, so as to facilitate the lubrication of the contact position between the fixed mold 3 and the plate-shaped aluminum original. During this process, the connecting spring 19 between the lifting guide rod 14 and the guide sleeve 18 is stretched to generate a rebound force. When the hydraulic telescopic rod 2 is extended to raise the movable mold 11, the main piston plate 13 slides down and resets along the main piston cylinder 12 under the action of the rebound force of the connecting spring 19. During this process, the main piston cylinder 12 sucks the fixed mold through the conduit 24. 3, it is convenient to recover part of the lubricating liquid. Obviously, there will be part of the lubricating liquid sticking to the side wall of the fixed mold 3 and the water-cooled plate after stamping, so it cannot be fully recovered. However, when the main piston plate 13 slides back and resets, it draws the lubricating liquid from the storage cylinder 8 through the one-way liquid inlet valve 26 and the suction pipe 9 to replenish it in the main piston cylinder 12, ensuring that after each reset of the main piston plate 13, a fixed amount of lubricating liquid is stored in the main piston cylinder 12, which is convenient for use. In addition, during each stamping operation, the lubricating oil in the fixed mold 3 that is not easy to disassemble is automatically recovered, and there is no need to worry about excessive use of the lubricating liquid and inconvenience in handling. The lubricating oil applied to the workpiece can be removed, so if there is excessive accumulation, it can be directly dumped for disposal.

[0056] And when the lifting guide rod 14 descends, causing the main piston plate 13 to descend, the main piston cylinder 12 sucks the lubricating liquid in the fixed mold 3 through the conduit 24. At this time, the lubricating liquid absorbs heat, and when the lifting guide rod 14 descends, it also drives the secondary piston plate 23 to descend. The secondary piston plate 23 compresses the liquid in the secondary piston cylinder 22 to flow into the heat exchange circulation pipe 20 through the one-way valve on one side, and then the liquid flows along the heat exchange circulation pipe 20 through the spiral tube body 25, and realizes heat exchange with the lubricating liquid in the winding conduit 24, absorbs the heat absorbed by the lubricating liquid, and cools the recovered lubricating liquid. When the lubricating liquid is transported to the fixed mold 3 again, the lubricating liquid can effectively absorb heat again to cool the fixed mold 3 and avoid thermal deformation.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
