Description

Technical Field

[0001] The invention relates to the technical field of automobile heat exchanger manufacturing, in particular to a high-efficiency and energy-saving automobile heat exchanger fin mould. Background Art

[0002] In the production process of automotive heat exchanger fins, traditional molds expose many problems that need to be solved; From the perspective of product quality, after long-term use, traditional molds are prone to residual waste and impurities on the mold surface. These residual substances will interfere with the dimensional accuracy of the fins during the fin stamping process, resulting in deviations in key dimensions such as the aperture and spacing of the fins, which cannot meet the strict automotive parts manufacturing standards. At the same time, impurities will also adhere to the surface of the fins, affecting their surface quality, causing unevenness, scratches and other defects on the fin surface, reducing the overall performance and service life of the heat exchanger. In addition, manual cleaning is often difficult to be comprehensive and thorough, and it is difficult to ensure that the mold surface reaches an ideal clean state after each cleaning, further increasing the instability of product quality. At the same time, the use and circulation of coolant are also prominent. The coolant circulation system of traditional molds is not designed reasonably. The coolant is often simply cooled once during use and then discharged directly, failing to achieve effective recycling. This not only wastes a lot of water resources and coolant, increases production costs, but also pollutes the environment. At the same time, since the coolant cannot be fully circulated, the mold cannot be continuously and effectively cooled during the long-term stamping process, which is prone to overheating, resulting in degradation and deformation of mold material performance, further affecting the service life of the mold and product quality; In view of the many disadvantages of traditional molds in cleaning efficiency, product quality, energy consumption and environmental protection, a new type of automobile heat exchanger fin mold is proposed, which can realize automatic cleaning, high efficiency and energy saving and easy impurity collection. This new mold will effectively solve the shortcomings of traditional molds and improve the production quality and efficiency of automobile heat exchanger fins. Summary of the invention

[0007] Furthermore, the circulation device includes a circulation box fixedly installed on the top of the frame, a filter plate is fixedly provided on the inner wall of the circulation box, a circulating water pump is fixedly provided at one end of the circulation box, a pumping pipe is fixedly provided below the circulating water pump, the pumping pipe is communicated with the circulation box, a drainage pipe is fixedly provided above the circulating water pump, a water distribution pipe is fixedly provided at one end of the drainage pipe, the water distribution pipe is fixedly installed on the inner side of the cleaning plate, a plurality of nozzles are evenly provided on one side of the water distribution pipe, and the nozzles are in the same direction as the cleaning connecting plate.

[0008] Furthermore, the filter plate is arranged at an inclination.

[0009] Furthermore, the sedimentation device includes a sedimentation box fixedly installed at one end of the frame, one end of the sedimentation box is connected to the circulation box, and a collecting box is movably provided in the sedimentation box, and the height of the collecting box is the same as the height of the lower end of the filter plate.

[0010] Furthermore, the composite device includes a composite plate fixedly mounted on one end of the scraping threaded rod, a composite threaded rod is fixedly arranged below the composite plate, a composite sleeve with thread adaptation is movably arranged below the composite threaded rod, a first gear is fixedly arranged below the composite sleeve, and a first transmission belt is adapted to the surface of the first gear; The composite device also includes a second gear installed in the circulation device. The second gear is divided into three groups. One end of the first transmission belt is matched with the second gear. The second transmission belt is symmetrically arranged on the surface of the second gear. A third gear is arranged at one end of the second transmission belt. A cooling fan is fixedly arranged under the third gear. A lifting sleeve is fixedly arranged above the third gear. A lifting threaded rod is adapted to the thread on the inner wall of the lifting sleeve. The lifting threaded rod is adapted to and communicated with the thread of the lower mold.

[0011] The beneficial effects of this technical solution are: (1) The cleaning device can remove fine impurities and residual waste on the surface of the lower mold by the close contact between the cleaning roller and the surface of the lower mold, avoiding the dimensional deviation or surface defects caused by impurities on the fin molding, thereby improving the dimensional accuracy and surface finish of the fin; The scraping device automatically cleans impurities on the lower surface of the upper mold during the rising and falling of the hydraulic plate to prevent these impurities from falling during the opening and closing of the mold or affecting the next material to be processed, effectively avoiding secondary pollution and ensuring the stable and reliable quality of each stamped fin.

[0012] (2) The coolant in the circulation device continuously cools and flushes the mold, which not only takes away the heat generated during the stamping process and prevents the mold from deformation and damage due to overheating, but also removes debris on the mold surface in time, reducing mold wear, thereby extending the service life of the mold and reducing the cost of mold replacement and maintenance.

[0013] (3) During the stamping process, the cleaning device, scraping device and circulation device work synchronously with the hydraulic device. When the hydraulic plate descends for stamping, the cleaning roller cleans the surface of the lower mold at the same time. The scraping device moves the scraper to a position that does not affect the stamping. The circulation device cools and rinses the mold, realizing multiple processes in parallel, shortening the production cycle of a single fin, and improving the overall production efficiency. The rapid cleaning action of the cleaning device and scraping device enables the mold to quickly restore to a clean state before and after each stamping, preparing for the next stamping, and reducing the production downtime caused by cleaning the mold.

[0014] (4) The circulation device realizes the recycling of coolant and reduces the consumption of coolant. Compared with the one-time use or simple circulation method of coolant in traditional molds, the circulation system of this mold can effectively filter and precipitate impurities in the coolant, so that the coolant always maintains good cooling and flushing performance, greatly reducing the amount of coolant replenishment and replacement frequency, saving water resources and coolant costs, and reducing the pollution of coolant emissions to the environment.

[0015] (5) The cooling fan in the composite device can cool down the lower mold in time, ensuring that the mold works at a suitable temperature, improving the molding accuracy and quality of the fins, and avoiding deformation of the mold due to high temperature. When the hydraulic plate is lifted and lowered to drive the scraping device up and down, the composite threaded rod in the scraping device moves up and down accordingly, driving the composite sleeve to rotate through the thread, thereby rotating the first gear, and the first gear drives the second gear through the first transmission belt, and the second gear drives the third gear through the second transmission belt, so that the cooling fan rotates at high speed, stirs the coolant in the circulation box, speeds up the heat dissipation of the coolant, enhances the cooling effect on the lower mold, ensures that the mold works in a stable temperature environment, and improves the dimensional accuracy and surface quality of fin molding; (6) The composite device cleverly utilizes the lifting movement of the hydraulic plate to realize the convenient demoulding of the formed fins. When the hydraulic press completes its work and the hydraulic plate rises, the scraping device drives the composite threaded rod to move upward, and the composite sleeve rotates through a series of transmissions, and finally the lifting threaded rod is pushed upward, and the formed fin mold is smoothly ejected from the lower mold, which is convenient for operators to take parts and improves production efficiency. When the hydraulic plate descends, the lifting threaded rod also descends, which will not hinder the next stamping work of the mold. The entire demoulding process has a high degree of automation, which reduces manual intervention and reduces labor intensity; BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] 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.

[0019] The specific implementation process is as follows: Embodiment 1: See also Figure 1-5The present invention provides a technical solution: an efficient and energy-saving automobile heat exchanger fin mold, including a frame 1, the frame 1 is welded with high-strength metal material to provide a stable support structure for the entire mold, a lifting tooth plate 101 is symmetrically welded on one side of the frame 1 to provide a power transmission basis for the scraping device 7, a hydraulic device 2 is installed under the frame 1, the hydraulic device 2 includes a hydraulic press 201 fixedly installed under the frame 1, the hydraulic press 201 is fastened to the frame 1 by high-strength bolts to ensure stability during work, a hydraulic plate 202 is fixed by a threaded connection under the hydraulic press 201, the hydraulic press 201 pressurizes the hydraulic oil through the internal hydraulic pump to push the piston to move, thereby driving the hydraulic plate 202 to move up and down linearly, and controlling the hydraulic pressure. The hydraulic oil flow and pressure of the press 201 can accurately control the lifting speed and stroke of the hydraulic plate 202, thereby driving the upper mold 3 and the lower mold 5 to realize the opening and closing action, and completing the stamping and forming of the fins. The upper mold 3 is also installed under the hydraulic plate 202 by threaded connection. The upper mold 3 is fixedly installed under the hydraulic device 2, and the circulation device 4 is fixedly installed above the frame 1. The circulation device 4 is fixed above the frame 1 by bolts. The circulation box 401 is made by welding technology, and the inner wall of the circulation box is fixed with an inclined filter plate 402 by welding. One end of the circulating water pump 403 is connected to the suction pipe 404 through a flange. The suction pipe 404 is connected to the circulation box 401, and the other end is connected to the drain pipe 405 through a flange. One end of the drain pipe 405 is connected to the water distribution pipe 4 through a three-way pipe fitting 06, the water distribution pipe 406 is installed on the inner side of the cleaning plate 601 through a clamp, and the nozzles 407 are evenly distributed on one side. The direction of the nozzles 407 is consistent with the direction of the cleaning connecting plate 602. Before and after the hydraulic punching, the circulating water pump 403 is started, and the high-speed rotation of the impeller is used to generate negative pressure to extract the coolant in the circulation box 401 through the suction pipe 404, and spray it from the nozzles 407 to the mold surface through the drainage pipe 405 and the water distribution pipe 406. Since the direction of the nozzles 407 is consistent with the direction of the cleaning connecting plate 602, the direction of the nozzles 407 can be adjusted synchronously according to the up and down movement of the hydraulic plate 202 to achieve cooling and flushing of the mold. The coolant carries the residue back to the circulation box 401 and is filtered through the filter plate 402. The residue flows along the inclined filter plate 4 02 Under the action of gravity, it flows into the collecting box 802 in the sedimentation box 801. The filtered coolant is pumped out by the circulating water pump 403 for recycling again. The lower mold 5 is fixedly installed in the circulation device 4, and the cleaning device 6 is fixedly installed under the hydraulic device 2. The cleaning device 6 is fixedly installed at both ends of the hydraulic plate 202 by bolts, including a cleaning plate 601. The cleaning shaft is installed at the axis of the cleaning plate 601 through a bearing so that the cleaning shaft can rotate flexibly. One side of the cleaning shaft is connected to the fixed cleaning connecting plate 602 through a key to ensure the effective transmission of torque. The cleaning roller 603 is movably installed at one end of the cleaning connecting plate 602 through the connecting shaft and the bearing so that the cleaning roller 603 can roll freely. When the hydraulic plate 202 descends, due to the relative position relationship between the cleaning shaft and the hydraulic plate 202,The cleaning connecting plate 602 will rotate around the cleaning axis, driving the cleaning roller 603 to move to the outermost side. During this process, the cleaning roller 603 contacts and rolls with the surface of the lower mold 5, and uses friction to clean impurities on the surface of the lower mold 5. At the same time, the positioning shaft 604 is movably installed at both ends of the hydraulic plate 202. The positioning telescopic rod 605 is fixed to the surface of the positioning shaft 604 by welding. A positioning spring is installed in the positioning telescopic rod 605, one end of which is connected to the positioning connecting plate 606 by welding. The positioning connecting plate 606 is welded and fixed above the cleaning connecting plate 602. During the movement of the cleaning roller 603, the positioning spring in the positioning telescopic rod 605 is compressed and deformed. According to the elastic characteristics of the spring, the contact pressure between the cleaning roller 603 and the lower mold 5 can be adaptively adjusted. , to ensure the cleaning effect, when the hydraulic plate 202 rises, the pressure on the cleaning roller 603 is reduced, the positioning spring resumes its extension, pushes the cleaning connecting plate 602 to drive the cleaning roller 603 to return to the inside, and cleans the mold surface again, and a scraping device 7 is movably installed under the hydraulic device 2, and the scraping device 7 is arranged in the hydraulic plate 202. The scraping groove 701 is formed by mechanical processing in the hydraulic plate 202, and a scraping threaded rod 702 is installed in the scraping groove 701. The two ends of the scraping threaded rod 702 are installed at both ends of the scraping groove 701 through bearing seats to ensure that it can rotate freely. One end of the scraping threaded rod 702 is connected to a fixed scraping gear 703 through a key, and the scraping gear 703 is meshed with the lifting gear plate 101. The surface of the scraping threaded rod 702 is matched by a thread Install the scraping slide plate 704, the scraping connecting plate 705 is connected to the scraping connecting plate 705 by bolts, and the scraping plate 706 is also connected to the scraping connecting plate 705 by bolts. When the hydraulic plate 202 descends or ascends, the scraping gear 703 meshes and rotates with the lifting gear plate 101, and according to the gear transmission principle, drives the scraping threaded rod 702 to rotate. Since the threads of the scraping slide plate 704 and the scraping threaded rod 702 cooperate, the rotation of the scraping threaded rod 702 will make the scraping slide plate 704 move forward and backward in a straight line, and then drive the scraping plate 706 to move forward and backward on the lower surface of the upper mold 3 through the scraping connecting plate 705. When the hydraulic plate 202 moves downward, the scraping plate 706 moves to the outermost side. At this time, the scraping plate 706 does not affect the hydraulic punching operation; when the hydraulic plate 202 When rising, the scraper 706 gradually moves inward, and in the process of moving, the residue on the surface of the upper mold 3 after punching is scraped and cleaned to prevent affecting the next hydraulic punching. A settling device 8 is fixedly installed at one end of the circulation device 4. The settling device 8 is fixed to one end of the frame 1 by bolts, and includes a settling box 801 and a collecting box 802. One end of the settling box 801 is connected to the circulation box 401 through a pipeline connection. The collecting box 802 is movably installed in the settling box 801. Slide rails are installed on both sides of the collecting box 802, which cooperate with the slide grooves in the settling box 801 to facilitate removal and cleaning. The height of the collecting box 802 is the same as the height of the lower end of the filter plate 402, and is used to collect the residue generated during the cleaning process. Working principle: the residue flows from the circulation box 401 into the settling box 801.Under the action of gravity, it settles into the collection box 802. When the collection box 802 is full of slag, it can be drawn out from the sedimentation box 801 through the slide rail for cleaning, so as to ensure the normal operation of the sedimentation device 8 and maintain the cleanliness of the coolant. A composite device 9 is provided in the circulation device 4. The composite device 9 includes a composite plate 901 fixedly installed at one end of the scraping threaded rod 702, a composite threaded rod 902 is fixedly provided below the composite plate 901, a composite sleeve 903 with threaded adaptation is movably provided below the composite threaded rod 902, a first gear 904 is fixedly provided below the composite sleeve 903, and the first gear The surface of the wheel 904 is adapted to be provided with a first transmission belt 905; the composite device 9 also includes a second gear 906 installed in the circulation device 4, the second gear 906 is three sets, one end of the first transmission belt 905 is adapted to the second gear 906, the surface of the second gear 906 is symmetrically provided with a second transmission belt 907, one end of the second transmission belt 907 is provided with a third gear 908, a cooling fan 909 is fixedly provided below the third gear 908, a lifting sleeve 910 is fixedly provided above the third gear 908, the inner wall thread of the lifting sleeve 910 is adapted to be provided with a lifting threaded rod 911, and the lifting threaded rod 911 is threadably matched with and communicated with the lower mold 5; the composite plate 901 is fixedly mounted on one end of the scraping threaded rod 702, so that the composite device is closely connected with the scraping device and can move following the movement of the scraping device; a composite threaded rod 902 is fixedly arranged below the composite plate 901, and the composite threaded rod 902 is threadably matched with the composite sleeve 903. When the composite threaded rod 902 moves up and down, the composite sleeve 903 can be driven to rotate by the threaded structure; the composite sleeve 903 is fixedly connected to the first gear 904 below to realize the transmission of the rotational motion; the first transmission belt 905 drives the first gear 90 4 is connected to the second gear 906. There are three groups of second gears 906, which are evenly distributed in the circulation device 4. The surface of each group of second gears 906 is symmetrically provided with a second transmission belt 907. One end of the second transmission belt 907 is connected to the third gear 908. A cooling fan 909 is fixedly provided below the third gear 908 to generate airflow to cool the lower mold 5. A lifting sleeve 910 is fixedly provided above. The inner wall of the lifting sleeve 910 is thread-matched with a lifting threaded rod 911. The lifting threaded rod 911 is thread-matched with and communicated with the lower mold 5, so as to realize the ejection operation of the formed fins. When in use, the operator places the material to be punched accurately on the surface of the lower die 5 to ensure the accurate position of the material and avoid deviation during the punching process, which affects the quality of fin forming; At this time, the hydraulic press 201 is in the initial state, the hydraulic plate 202 and the upper mold 3 are in the high position; the cleaning roller 603 in the cleaning device 6 is in the initial position on the inside, and the positioning spring in the positioning telescopic rod 605 is in the natural extension state; the scraper 706 of the scraping device 7 is located on the inside; the circulating water pump 403 of the circulation device 4 is in the standby state, and a proper amount of coolant is stored in the circulation box 401; The control device issues a command to start the hydraulic press 201, and the hydraulic pump inside the hydraulic press 201 starts to work, pressurizes the hydraulic oil and pushes the piston to move, thereby driving the hydraulic plate 202 and the upper mold 3 to move downward at a set speed and pressure, and the upper mold 3 gradually approaches the lower mold 5 to punch the material to be punched, completing the punching forming of the fin; At the same time, during the descent of the hydraulic plate 202, the cleaning plate 601 is synchronously descended with the hydraulic plate 202. Due to the relative positional relationship between the cleaning shaft and the hydraulic plate 202, the cleaning connecting plate 602 starts to rotate around the cleaning shaft. As the cleaning connecting plate 602 rotates, the cleaning roller 603 connected to one end thereof moves from the inside to the outside. During the movement, the cleaning roller 603 is in close contact with the surface of the lower mold 5 and rolls. Due to the action of the positioning spring in the positioning telescopic rod 605, the cleaning roller 603 always maintains a suitable pressure with the surface of the lower mold 5, thereby effectively removing impurities on the surface of the lower mold 5, such as residual debris, oil stains, etc., and providing a clean mold surface for the next stamping. In this process, the positioning spring is deformed and shortened by the pressure generated by the movement of the cleaning roller 603. At the same time, the scraping gear 703 on one side of the hydraulic plate 202 begins to mesh with the lifting tooth plate 101. As the hydraulic plate 202 descends, the scraping gear 703 begins to rotate under the action of the lifting tooth plate 101. The rotation of the scraping gear 703 drives the scraping threaded rod 702 keyed thereto to rotate. Since the scraping slide plate 704 and the scraping threaded rod 702 are threadedly matched, the rotation of the scraping threaded rod 702 causes the scraping slide plate 704 to move outward along the scraping groove 701. The scraping slide plate 704 drives the scraper 706 to move outward synchronously through the scraping connecting plate 705. When the hydraulic plate 202 descends to the punching position, the scraper 706 moves to the outermost side, and at this time, the scraper 706 maintains a certain distance from the lower surface of the upper mold 3, which does not affect the hydraulic punching operation. The circulating water pump 403 is started at the beginning of stamping. The circulating water pump 403 uses the high-speed rotation of the impeller to generate negative pressure, and the coolant in the circulation box 401 is pumped out through the pumping pipe 404. The coolant enters the water distribution pipe 406 through the drain pipe 405. Since the water distribution pipe 406 is installed on the inner side of the cleaning plate 601, and the direction of the nozzle 407 is consistent with the direction of the cleaning connecting plate 602, the coolant is sprayed from the nozzle 407 to cool and rinse the cleaning roller 603 and the surface of the lower mold 5. The coolant not only takes away the heat generated during the stamping process to prevent the mold from being damaged due to overheating, but also rinses away the impurities cleaned by the cleaning roller 603, so that it flows back to the circulation box 401 with the coolant; After the stamping is completed, the control device controls the hydraulic press 201 to work in the reverse direction, and the hydraulic pump refluxes the hydraulic oil, so that the hydraulic plate 202 and the upper mold 3 move upwards and return; As the hydraulic plate 202 rises, the pressure on the cleaning roller 603 gradually decreases, and the positioning spring in the positioning telescopic rod 605 begins to stretch again. The elongation of the positioning spring pushes the positioning telescopic rod 605, and then applies thrust to the cleaning connecting plate 602, so that the cleaning connecting plate 602 drives the cleaning roller 603 to move from the outside to the inside to restore to the initial position. During the movement, the cleaning roller 603 cleans the mold surface again to ensure that there is no residual impurity on the mold surface; During the rising process of the hydraulic plate 202, the scraping gear 703 meshes and rotates with the lifting gear plate 101 again. Due to the connection between the scraping gear 703 and the scraping threaded rod 702, the scraping threaded rod 702 rotates accordingly, so that the scraping slide plate 704 moves inward along the scraping groove 701. The scraping slide plate 704 drives the scraper 706 to move inward through the scraping connecting plate 705. The scraper 706 scrapes and cleans the lower surface of the upper mold 3 during the movement, and scrapes off the residues left after stamping to avoid affecting the next stamping. The coolant carries the residue cleaned from the mold surface and flows back to the circulation box 401. It first passes through the inclined filter plate 402. Due to the inclined setting of the filter plate 402, the residue slides down along the filter plate 402 under the action of gravity and finally flows into the collection box 802 in the sedimentation box 801. The filtered coolant remains in the circulation box 401, waiting for the next circulation. At the same time, when the hydraulic plate 202 starts to move up and down, it drives the scraping device 7 to move up and down synchronously. Since the composite plate 901 is fixed at one end of the scraping threaded rod 702, the movement of the scraping device 7 will drive the composite threaded rod 902 to move up and down. During the up and down movement of the composite threaded rod 902, according to the principle of thread transmission, the composite sleeve 903 threadably adapted thereto will produce a rotational motion. The rotation of the composite sleeve 903 drives the first gear 904 fixedly connected below to rotate synchronously. The first gear 904 transmits the rotational motion to the second gear 906 through the first transmission belt 905. Since the second gear 906 is divided into three groups, the movement of the first transmission belt 905 can simultaneously drive the three groups of second gears 906 to rotate. Each group of second gears 906 then drives the corresponding third gear 908 to rotate through its respective second transmission belt 907. At this time, the cooling fan 909 below the third gear 908 rotates at high speed to stir and cool the circulation box 401. Liquid, speeds up the heat dissipation speed of the coolant, enhances the cooling effect on the lower mold 5, ensures that the mold works at a suitable temperature, and improves the fin forming quality. At the same time, the lifting sleeve 910 above the third gear 908 will also rotate with the rotation of the third gear 908. Since the lifting sleeve 910 is threadedly adapted to the lifting threaded rod 911, the rotation of the lifting sleeve 910 will cause the lifting threaded rod 911 to move up and down. When the hydraulic press completes the work and the hydraulic plate 202 rises, through the above series of transmissions, the lifting threaded rod 911 is ejected upward, and the formed fin mold is smoothly ejected from the lower mold 5, which is convenient for the operator to take the parts. When the hydraulic plate 202 descends, the reverse transmission process causes the lifting threaded rod 911 to descend, which will not hinder the next stamping work of the mold. The entire operation process cleverly utilizes the lifting and lowering movement of the hydraulic plate 202, realizes multiple functions such as cooling and demoulding of the mold, and improves the working efficiency and intelligence of the mold.
