Description

Technical Field

[0001] The present invention relates to the technical field of forging dies, and more specifically, to a forging die for a water pump pump body. Background Art

[0002] A water pump is a pump specifically used for transporting clean water or other liquids with physical and chemical properties similar to water, and its characteristic is that the liquid does not contain solid particles, corrosive substances or fibers and other impurities.

[0003] During the use of existing forging dies, it is necessary to continuously use running water to cool the dies. The temperature during the forging process is very high, and the metal material needs to withstand huge pressure in the die after being heated to the forging temperature. Due to the long-term high-temperature effect, if the die temperature is too high, it will cause the die to thermally expand and even deform, affecting the use accuracy of the die and the quality of the forged product.

[0004] In response to the above problems, some solutions have also been given in the prior art. For example, the Chinese invention application with the publication number CN119681186A discloses a forging die for a star-shaped sleeve. By setting a fixing mechanism and a telescopic mechanism, cooling water is accurately sucked in during the forging process and evenly distributed on the surfaces of the upper template and the lower template through a spraying component, effectively improving the quality of the forged product. Although the prior art can improve the forging quality to a certain extent, when spraying cold water onto the template, it is inevitable that the cold water will splash onto the blank, and due to the close fit between the die bottom plate and the workpiece, the heat dissipation effect is poor. Moreover, in the prior art, by spraying water onto the template surface, the bottom wall of the die cannot be effectively cooled, thus seriously affecting the product quality. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a forging die for a water pump pump body, which can achieve the purpose of improving product quality.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A forging die for a water pump pump body includes a workbench, a frame body is fixedly installed on the top wall of the workbench, a forging component is arranged on the frame body, a lower die is fixedly installed on the top wall of the workbench, and a cooling component is arranged on the lower die; The cooling component includes a cooling cavity opened on the lower die, a water storage box is fixedly installed on the workbench, a piston plate is slidably installed in the water storage box, a water inlet valve and a drain valve are respectively inserted on the piston plate, and a first water pipe communicated with the cooling cavity is installed on the output end of the drain valve. A drain pipe extending into the water storage box is inserted in the cooling cavity, and a pushing component for pushing the blank out of the lower die after forging is arranged on the lower die.

[0008] Furthermore, the forging assembly includes a hydraulic rod fixedly installed on the top wall of the frame body. An installation plate is fixedly installed at the output end of the hydraulic rod. An upper mold is fixedly installed on the bottom wall of the installation plate. Connecting rods fixedly connected to the piston plate are uniformly and fixedly installed on the installation plate.

[0009] Furthermore, elastic rods are uniformly and fixedly installed on the top wall of the cooling chamber. A sleeve is fixedly installed on the elastic rod. An installation rod is slidably installed in the sleeve. An elastic heat-conducting rod fixedly connected to the lower mold is fixedly installed on the installation rod.

[0010] Furthermore, a shape memory alloy wire is jointly installed between the top wall of the installation rod and the lower mold. A first spring is jointly installed between the installation rod and the sleeve. A jitter assembly cooperating with the installation rod is arranged in the cooling chamber.

[0011] Furthermore, the jitter assembly includes an installation box fixedly installed on the bottom wall of the cooling chamber. A vertical plate is slidably installed in the installation box. A second spring is jointly installed between the vertical plate and the installation box. A chute is formed on the installation box. A connecting plate is slidably installed in the chute. A linkage frame cooperating with the installation rod is fixedly installed on the connecting plate. The linkage frame is horizontally slidably matched with the cooling chamber.

[0012] Furthermore, the pushing-out assembly includes an electric push rod fixedly installed on the lower mold. A push plate is fixedly installed on the electric push rod.

[0013] Furthermore, an air chamber is formed on the push plate. Pressure relief holes are uniformly formed on the air chamber. An air pipe communicating with the cooling chamber is inserted into the air chamber. A linkage assembly cooperating with the pressure relief holes is arranged on the electric push rod.

[0014] Furthermore, the linkage assembly includes an installation ring slidably installed on the electric push rod. A pull rod is jointly and fixedly installed between the installation ring and the push plate. Horizontal rods are symmetrically and fixedly installed on the installation ring. An installation frame vertically slidably matched with the cooling chamber is fixedly installed on the horizontal rods. Protrusions are uniformly and fixedly installed on the installation frame. Inclined blocks are uniformly and fixedly installed on the sleeve.

[0015] Furthermore, the surface of the protrusion is a smooth mirror surface.

[0016] Furthermore, a refrigerator is fixedly installed on the water storage box.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this solution, by opening a cooling chamber, during the process of the installation plate driving the upper die to forge the blank, the connecting rod drives the piston plate to reciprocate up and down. And during the movement of the piston plate, it drives cold water to continuously flow through the cooling chamber. When the cold water passes through the cooling chamber, it can absorb the heat of the lower die, thus realizing the cooling of the lower die. At the same time, because the water flow is in the cooling chamber, it can avoid the evaporation loss of the water flow and avoid the damage of the blank caused by the contact between the water flow and the blank. Moreover, by cooling through the water flow passing through the cooling chamber, the bottom wall of the lower die can be directly cooled, thereby improving the heat dissipation effect of the lower die, effectively avoiding the decline in product quality caused by the thermal expansion of the lower die, and playing a role in improving product quality. (2) In this solution, by setting an elastic heat-conducting plate, when the temperature of the upper die is too high, the shape memory alloy wire will be heated and extended. At this time, the first spring contracts and drives the installation rod to move downward. Then, during the downward movement of the installation rod, it drives the elastic heat-conducting rod into the water flow in the cooling chamber. The elastic heat-conducting rod can quickly conduct the heat of the lower die into the water flow and improve the cooling effect of the lower die, so that the temperature of the lower die is kept within a controllable range, further improving the product quality. (3) In this solution, by setting a linkage frame, after the water flow passes through the drain valve and flows to the first water pipe, the water flow flows into the installation box and drives the vertical plate to move. And during the movement of the vertical plate, it drives the connecting plate to move along the chute. During the movement of the linkage frame, it will gradually contact the installation rod and apply a thrust to the installation rod. Then, under the action of the thrust, the installation rod drives the elastic rod to deform through the sleeve. When the linkage frame disengages from the installation rod, the elastic rod drives the elastic heat-conducting rod to swing back and forth in the water flow through the sleeve and the installation rod, thereby further improving the cooling effect of the lower die, effectively avoiding the high-temperature deformation of the lower die from affecting the product quality, and further improving the product quality.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 7 , a forging die for a water pump pump body, including a workbench 1, a frame 2 is fixedly installed on the top wall of the workbench 1, a forging component 5 is arranged on the frame 2, a lower die 3 is fixedly installed on the top wall of the workbench 1, and a cooling component 4 is arranged on the lower die 3; The cooling component 4 includes a cooling chamber 401 opened on the lower die 3, a water storage box 402 is fixedly installed on the workbench 1, a piston plate 403 is slidably installed in the water storage box 402, a water inlet valve 405 and a drain valve 406 are respectively inserted on the piston plate 403, and a first water pipe 407 communicating with the cooling chamber 401 is installed on the output end of the drain valve 406. A drain pipe 408 extending into the water storage box 402 is inserted into the cooling chamber 401, and a pushing component 8 for pushing the billet out of the lower die 3 after forging is arranged on the lower die 3.

[0022] The forging assembly 5 includes a hydraulic rod 501 fixedly installed on the top wall of the frame body 2. A mounting plate 502 is fixedly installed at the output end of the hydraulic rod 501. An upper die 503 is fixedly installed on the bottom wall of the mounting plate 502. Connecting rods 504 fixedly connected to the piston plate 403 are uniformly installed on the mounting plate 502.

[0023] During use, the blank is placed on the lower die 3. Then, the hydraulic rod 501 drives the upper die 503 to move downward through the mounting plate 502 and forges the blank. At the same time, during the downward movement of the mounting plate 502, the piston plate 403 is driven to move downward through the connecting rod 504. And during the downward movement of the piston plate 403, the cold water located below the piston plate 403 in the water storage box 402 is squeezed, and the cold water flows through the drain valve 406 and the first water pipe 407 to the cooling chamber 401 and then flows into the water storage box 402 through the drain pipe 408 on the cooling chamber 401. When the cold water passes through the cooling chamber 401, it can absorb the heat of the lower die 3, thereby realizing the cooling of the lower die 3. At the same time, because the water flow is in the cooling chamber 401, it can avoid the evaporation loss of the water flow and avoid the damage of the blank caused by the contact between the water flow and the blank. Moreover, by cooling through the water flow passing through the cooling chamber 401, the bottom wall of the lower die 3 can be directly cooled, thereby improving the heat dissipation effect of the lower die 3, effectively avoiding the reduction of product quality caused by the thermal expansion of the lower die 3, and playing a role in improving product quality.

[0024] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown in, elastic rods 601 are uniformly fixedly installed on the top wall of the cooling chamber 401. A sleeve 602 is fixedly installed on the elastic rod 601. A mounting rod 603 is slidably installed in the sleeve 602. An elastic heat conducting rod 604 fixedly connected to the lower die 3 is fixedly installed on the mounting rod 603.

[0025] A shape memory alloy wire 605 is jointly installed between the top wall of the mounting rod 603 and the lower die 3. A first spring 606 is jointly installed between the mounting rod 603 and the sleeve 602. A shaking assembly 7 cooperating with the mounting rod 603 is arranged in the cooling chamber 401.

[0026] The shaking assembly 7 includes a mounting box 701 fixedly installed on the bottom wall of the cooling chamber 401. A vertical plate 702 is slidably installed in the mounting box 701. A second spring 703 is jointly installed between the vertical plate 702 and the mounting box 701. A chute 704 is formed on the mounting box 701. A connecting plate 705 is slidably installed in the chute 704. A linkage frame 706 cooperating with the mounting rod 603 is fixedly installed on the connecting plate 705. And the linkage frame 706 is in horizontal sliding fit with the cooling chamber 401.

[0027] By adopting the above technical solution, in the initial state, the first spring 606 is in a stretched state. By setting the elastic heat-conducting rod 604, the heat exchange efficiency between the lower die 3 and the cooling chamber 401 can be improved, thereby enhancing the cooling effect of the lower die 3. When the temperature of the upper die 503 is too high, the shape memory alloy wire 605 will expand when heated. At this time, the first spring 606 contracts and drives the mounting rod 603 to move downward. Then, during the downward movement of the mounting rod 603, the elastic heat-conducting rod 604 is driven into the water flow in the cooling chamber 401. The elastic heat-conducting rod 604 can quickly conduct the heat of the lower die 3 into the water flow. When the temperature of the lower die 3 is within the controllable range, the shape memory alloy wire 605 gradually contracts and drives the mounting rod 603 to reset upward. That is, through the cooperation of the shape memory alloy wire 605 and the elastic heat-conducting rod 604, the cooling effect of the lower die 3 can be improved, so that the temperature of the lower die 3 is maintained within the controllable range, further improving the product quality.

[0028] After the water flow flows through the drain valve 406 and into the first water pipe 407, the water flow flows into the mounting box 701, increasing the pressure inside the mounting box 701. Then, under the action of the pressure, the water flow drives the vertical plate 702 to move. At this time, the second spring 703 is compressed and has a tendency to recover. And during the movement of the vertical plate 702, the connecting plate 705 is driven to move along the sliding groove 704. When the vertical plate 702 passes through the sliding groove 704, the water flow in the water tank flows into the cooling chamber 401 through the sliding groove 704. And when the water flow entering the mounting box 701 is balanced with the water flow flowing out through the sliding groove 704, the vertical plate 702 stops moving. Meanwhile, during the movement of the connecting plate 705, the linkage frame 706 is driven to move. Then, during the movement of the linkage frame 706, it will gradually come into contact with the mounting rod 603 and exert a thrust on the mounting rod 603. Under the action of the thrust, the mounting rod 603 drives the elastic rod 601 to deform through the sleeve 602. When the linkage frame 706 disengages from the mounting rod 603, the elastic rod 601 drives the elastic heat-conducting rod 604 to swing back and forth in the water flow through the sleeve 602 and the mounting rod 603, thereby further improving the cooling effect of the lower die 3, effectively preventing the lower die 3 from deforming due to high temperature and affecting the product quality, and further improving the product quality.

[0029] When the piston plate 403 stops moving downward, the second spring 703 contracts and drives the connecting plate 705 to move through the vertical plate 702. And during the movement of the connecting plate 705, the linkage frame 706 is gradually reset, playing a role in preparing for the next operation.

[0030] As Figure 3 、 Figure 7 shown, the pushing component 8 includes an electric push rod 801 fixedly installed on the lower die 3, and a push plate 802 is fixedly installed on the electric push rod 801.

[0031] An air cavity 803 is formed on the push plate 802, pressure relief holes 804 are evenly formed on the air cavity 803, and an air pipe 805 communicating with the cooling cavity 401 is inserted on the air cavity 803, and a linkage assembly 9 cooperating with the pressure relief holes 804 is arranged on the electric push rod 801.

[0032] The linkage assembly 9 includes a mounting ring 901 slidably mounted on the electric push rod 801. A pull rod 902 is fixedly installed between the mounting ring 901 and the push plate 802. Horizontal rods 903 are symmetrically and fixedly installed on the mounting ring 901. An installation frame 904 vertically slidably matched with the cooling cavity 401 is fixedly installed on the horizontal rods 903. Protrusions 905 are evenly and fixedly installed on the installation frame 904. Inclined blocks 906 are evenly and fixedly installed on the sleeve 602.

[0033] By adopting the above technical solution, when it is necessary to push out the blank after forging, the user can control the output end of the electric push rod 801 to extend. During the extension of the output end of the electric push rod 801, the push plate 802 is driven to move upward. During the upward movement of the push plate 802, the blank after forging is driven to move upward and gradually separate from the lower die 3. Since the blank after forging is closely attached to the lower die 3, if an external force is used to forcibly remove the blank, it is easy to cause damage to the blank and affect the product quality, which plays a role in improving the product quality.

[0034] During the high-temperature forging process of the blank, the bottom wall of the blank will gradually be closely attached to the cavity of the lower die 3, and as the temperature of the blank decreases, a negative pressure will be formed between the blank and the lower die 3. During the upward movement of the push plate 802, the pressure relief holes 804 are driven to gradually communicate with the cavity of the lower die 3. At this time, the air flow in the cooling cavity 401 can flow to the joint between the lower die 3 and the blank through the air pipe 805, the air cavity 803, and the pressure relief holes 804, so as to prevent the bottom wall of the blank from being closely sucked together with the lower die 3 and prevent the blank from being damaged due to excessive thrust during the process of removing the blank, further improving the product quality.

[0035] During the upward movement of the push plate 802, the mounting ring 901 is driven to move upward through the pull rod 902. During the upward movement of the mounting ring 901, the installation frame 904 is driven to move upward through the horizontal rods 903. Then, during the upward movement of the installation frame 904, the protrusions 905 are driven to move upward. During the upward movement of the protrusions 905, the inclined blocks 906 will be impacted. Then, the impact force is transmitted to the elastic rod 601 through the sleeve 602 by the inclined blocks 906, and the elastic rod 601 is caused to vibrate. Then, the vibration is transmitted to the lower die 3 by the elastic rod 601, and the lower die 3 is caused to vibrate slightly, so as to facilitate the air flow to the joint between the blank and the lower die 3, further improving the product quality.

[0036] As Figure 7 shown, the surface of the bump 905 is a smooth mirror surface.

[0037] By adopting the above technical solution, during the process of the bump 905 hitting the inclined block 906, friction will occur between the bump 905 and the inclined block 906. By making the surface of the bump 905 a smooth mirror surface, the friction force between the bump 905 and the inclined block 906 can be reduced, ensuring that the bump 905 can normally hit the inclined block 906.

[0038] As Figure 2 shown, a cooler 10 is fixedly installed on the water storage box 402.

[0039] By adopting the above technical solution, when the water flow in the cooling chamber 401 flows towards the water storage box 402, the cooler 10 can cool the water flow in the water storage box 402, thereby ensuring that the water flow in the water storage box 402 remains at a low temperature, thus improving the cooling effect of the mold.

[0040] Usage method: During use, place the blank on the lower die 3, and then the hydraulic rod 501 drives the upper die 503 to move downward through the mounting plate 502 and forges the blank. At the same time, during the downward movement of the mounting plate 502, the piston plate 403 is driven to move downward through the connecting rod 504. And during the downward movement of the piston plate 403, the cold water located below the piston plate 403 in the water storage box 402 is squeezed, and the cold water flows through the drain valve 406 and the first water pipe 407 to the cooling chamber 401, and then flows into the water storage box 402 through the drain pipe 408 on the cooling chamber 401. When the cold water passes through the cooling chamber 401, it can absorb the heat of the lower die 3; when the temperature of the upper die 503 is too high, the shape memory alloy wire 605 will expand when heated. At this time, the first spring 606 contracts and drives the mounting rod 603 to move downward. Then, during the downward movement of the mounting rod 603, the elastic heat conducting rod 604 is driven into the water flow in the cooling chamber 401. The elastic heat conducting rod 604 can quickly conduct the heat of the lower die 3 into the water flow; after the water flow flows through the drain valve 406 to the first water pipe 407, the water flow flows into the mounting box 701, and the pressure in the mounting box 701 increases. Then, under the action of the pressure, the water flow drives the vertical plate 702 to move. During the movement of the connecting plate 705, the linkage frame 706 is driven. Then, during the movement of the linkage frame 706, it will gradually come into contact with the mounting rod 603 and exert a thrust on the mounting rod 603. Then, under the action of the thrust, the mounting rod 603 drives the elastic rod 601 to deform through the sleeve 602. When the linkage frame 706 disengages from the mounting rod 603, the elastic rod 601 drives the elastic heat conducting rod 604 to swing back and forth in the water flow through the sleeve 602 and the mounting rod 603, thereby further improving the cooling effect of the lower die 3; during the upward movement of the push plate 802, the pressure relief hole 804 is gradually driven to communicate with the cavity of the lower die 3. At this time, the air flow in the cooling chamber 401 can flow through the air pipe 805, the air cavity 803, and the pressure relief hole 804 to the joint between the lower die 3 and the blank, so as to prevent the bottom wall of the blank from being tightly sucked together with the lower die 3; during the upward movement of the push plate 802, the mounting ring 901 is driven to move upward through the pull rod 902. And during the upward movement of the mounting ring 901, the mounting frame 904 is driven to move upward through the horizontal rod 903. Then, during the upward movement of the mounting frame 904, the convex block 905 is driven to move upward. And during the upward movement of the convex block 905, it will hit the inclined block 906. Then, the inclined block 906 transmits the impact force to the elastic rod 601 through the sleeve 602, and the elastic rod 601 shakes. Then, the elastic rod 601 transmits the shake to the lower die 3, and the lower die 3 shakes slightly, so as to facilitate the air flow to flow to the joint between the blank and the lower die 3.

[0041] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
