Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a cooling device for stamping dies for automotive stamping parts. Background Technology

[0002] In automotive parts manufacturing, metal parts are stamped to form automotive components. Some metal parts become automotive components directly after stamping, while others require further processing such as welding, machining, or painting before becoming automotive components. Stamping dies are special process equipment used in cold stamping to process materials into parts; these are called cold stamping dies. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing separation or plastic deformation to obtain the desired parts. Stamping requires dies and cooling devices to lower their temperature.

[0003] For example, patent application number 202022949039.1 discloses a cooling device for stamping dies of automotive stamping parts, including: a base plate, a water tank, a fan and a lifting plate. Vertical rods are fixedly connected to the top of the base plate, and the end of the vertical rod away from the base plate is fixedly connected to the top plate. A hydraulic telescopic rod is fixedly installed on the end of the top plate facing the base plate, and the lifting plate is fixedly connected to the telescopic end of the hydraulic telescopic rod.

[0004] The cooling device for automotive stamping dies has the following disadvantages: Although the fan is always blowing air onto the punch on the lifting plate and water mist is sprayed onto the die holder through the nozzle to cool the die holder and prevent the temperature of the punch and die holder from rising with the increase of working time, it is not convenient to cool the punch and die holder simultaneously during the cooling process. In addition, the cooling water after cooling will be mixed with particulate matter or impurities generated during the stamping process, which is not convenient for recycling and reuse of cooling water, thus reducing cooling efficiency, wasting water resources, and having limited adaptability.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0021] In one embodiment, the cooling assembly 13 includes a fixing member 1301 disposed at the bottom of the top plate 3. A driving member 1302 is sleeved on the outer circumference of the bottom of the fixing member 1301. The fixing member 1301 includes a fixing plate 13011 symmetrically disposed at the bottom of the top plate 3. A ring 13012 is disposed at the bottom of the fixing plate 13011. An annular groove 13013 is formed on the inner wall of the ring 13012. A plurality of toothed grooves 13014 are provided on the inner wall of the annular groove 13013. The driving member 1302 includes a housing 13021 sleeved on the outer side of the ring 13012. A first servo motor 13 is disposed at the inner bottom end of the housing 13021. 022, the output end of the first servo motor 13022 is connected to a gear 13023 that meshes with the tooth groove 13014; the bottom end of the housing 13021 is provided with a mounting base 13024, the inside of the mounting base 13024 is connected to a connecting block 13025, the end of the connecting block 13025 is provided with a spray plate 13026, and one side wall of the spray plate 13026 is connected to the connecting hose 12 through, so that under the action of the cooling component 13, the upper stamping die 5 and the lower stamping die 7 can be cooled by water at multiple angles at the same time, avoiding uneven cooling, thereby improving the cooling efficiency of the automotive stamping die cooling device and making it more adaptable.

[0022] The specific working principle of the cooling component 13 is as follows: When cooling of the upper stamping die 5 and the lower stamping die 7 is required, the first servo motor 13022 is started through the control panel 21. The output shaft of the first servo motor 13022 drives the gear 13023 to rotate. With the cooperation of the gear 13023 and the tooth groove 13014, the housing 13021 is driven to move in a circular motion on the ring 13012. Under the action of the housing 13021, the connecting block 13025 is driven to move. Under the action of the connecting block 13025, the spray plate 13026 is driven to move, so that the spray plate 13026 can perform water cooling of the upper stamping die 5 and the lower stamping die 7 in the direction of rotation of the housing 13021. The operator can control the first servo motor 13022 to rotate half a turn forward through the control panel 21, thereby driving... The housing rotates half a turn clockwise, which in turn drives the spray plate 13026 to rotate half a turn clockwise, thus cooling the upper stamping die 5 and the lower stamping die 7 in one direction. Then, the control panel 21 controls the first servo motor 13022 to reset, and then the control panel 21 controls the first servo motor 13022 to rotate half a turn counterclockwise, which drives the housing to rotate half a turn counterclockwise, which in turn drives the spray plate 13026 to rotate half a turn counterclockwise, thus cooling the upper stamping die 5 and the lower stamping die 7 in the opposite direction. Then, the control panel 21 controls the first servo motor 13022 to reset, and the above operation is repeated to complete the multi-directional cooling of the upper stamping die 5 and the lower stamping die 7. During this process, the rotation angle and direction of the first servo motor 13022 are reasonable, avoiding the entanglement of the connecting hose 12.

[0023] In one embodiment, the filter assembly 14 includes a filter element 1401 positioned at the top of the top plate 3, a recovery element 1402 on one side of the filter element 1401, and a filter box 14011 positioned at the top of the top plate 3. A filter seat 14012 is located at one end of the interior of the filter box 14011. The top of the filter seat 14012 is stepped, and several augers 14013 are located on the top of the filter seat 14012. One side of each auger 14013 penetrates the side wall of the filter box 14011 and is connected to a second servo motor 14014. Several filter plates 14015 are located at one end of each auger 14013. A push-pull plate 14016 is located at the top of the filter box 14011, and several filter holes 14017 are located on the side wall of one end of each filter plate 14015. Furthermore, the aperture size of the filter hole 14017 gradually decreases from top to bottom along a stepped direction. The recovery component 1402 includes several discharge pipes 14021 that penetrate through the other side of the filter box 14011, and each discharge pipe 14021 is matched with the other side of the auger 14013. Each discharge pipe 14021 is provided with a control valve 14022 on its outer side. Each discharge pipe 14021 is connected to a collection box 14023, and a pull door 14024 is opened on one side wall of the collection box 14023. This allows the cooling water to be filtered in stages under the action of the filter assembly 14, and different sizes of particles and impurities can be removed step by step. This avoids the impurities and particles from affecting the subsequent cooling work, improves the efficiency of cooling water recycling, and thus improves the subsequent working efficiency of the automotive stamping part stamping die cooling device.

[0024] The specific working principle of the filter assembly 14 is as follows: After the cooling water enters the filter box 14011 through the first connecting pipe 15, it will filter the impurities in the cooling water step by step through the stepped filter plates 14015. Then, the filtered cooling water is discharged through the second connecting pipe 18. After filtration, the rotation of the second servo motor 14014 can drive the auger 14013 to rotate, and then the filtered impurities can be transported to the discharge pipe 14021 and then enter the collection box 14023 for collection, which is convenient for subsequent processing.

[0025] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0026] In practical applications, when the temperature of the upper stamping die 5 and the lower stamping die 7 is too high after stamping, the first water pump 11 is started through the control panel 21 to draw out the cooling water in the water tank 9 through the first water suction pipe 10, and then the cooling water is delivered to the cooling assembly 13 through the connecting hose 12. At this time, the cooling assembly 13 is started to perform multi-directional cooling and temperature reduction on the upper stamping die 5 and the lower stamping die 7. During the cooling process, the dripping cooling water enters the base 1 through the return hole 8. Then, the second water pump 16 is started to send the cooling water inside the base 1 to the filter assembly 14 through the second water suction pipe 17 and the first connecting pipe 15 for graded filtration to avoid impurities and particles in the cooling water from affecting the subsequent cooling work. Finally, the third water pump 19 is started to send the filtered cooling water to the water tank 9 through the second connecting pipe 18 and the inlet pipe 20 for subsequent cooling work.
