[0002] With the rapid development of modern industry, the status of sheet metal stamping technology in the manufacturing industry has become increasingly prominent and has become an indispensable part of the manufacturing of many key products. However, the existing stamping process often faces many challenges in practical applications;

[0003] First, during the stamping process, the mold will be subjected to various thermal effects such as friction and impact, resulting in uneven temperature distribution. This uneven heating state will cause thermal stress in the mold, which will in turn cause deformation and wear, seriously affecting the life of the mold and the accuracy of the stamped parts;

[0004] In addition, the lack of a device for cleaning the stamping die cavity is also a problem faced by traditional stamping processes. During the stamping process of metal sheets, a certain amount of debris and impurities will be generated in the cavity due to the shearing and deformation of the material. Failure to clean them in time will affect the normal operation and maintenance of the equipment. Utility Model Content

[0005] The utility model provides a stamping forming device for mold processing, aiming to solve the problems often faced by the existing stamping process, such as unstable performance of metal sheets, uneven heating of molds and inability to clean the cavity in time. These problems not only affect the quality and precision of stamped parts, but also reduce production efficiency and increase safety risks.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a stamping forming device for mold processing, such as Figure 1-4 As shown, it includes a support base 1; a lower mold cavity 2 arranged in the support base 1; a cooling groove 3 arranged on the outer side of the lower mold cavity 2, and the cooling groove 3 is distributed in a ring shape; a box body 4 is arranged on both sides of the support base 1; a vertical plate 5 is arranged in the two boxes 4, and the vertical plate 5 divides the box body 4 into two independent cavities; a pump body 6 is arranged in one of the cavities of the two boxes 4, one end of the two pump bodies 6 passes through the vertical plate 5 and is connected to the other cavity, and the other ends of the two pump bodies 6 are connected to the cooling groove 3 through a conduit 7; a reserved groove 8 is arranged at the top position of one of the boxes 4; a cooling fan 9 is arranged in the reserved groove 8; and a heating block 10 is arranged in the other box body 4.

[0023] It should be noted that the existing stamping process often faces problems such as unstable performance of metal sheets, uneven heating of molds, and inability to clean the cavity in time. These problems not only affect the quality and precision of the stamped parts, but also reduce production efficiency and increase safety risks. The present solution uses a heating block 10 to preheat the liquid to ensure that the metal sheet reaches an ideal temperature state before stamping. This preheating method and the uniform distribution design of the cooling groove 3 allow the mold to be uniformly preheated, thereby improving the plasticity of the metal sheet and reducing deformation resistance. After the stamping is completed, the mold and workpiece are quickly cooled by the coolant, further improving the precision and surface quality of the stamped parts. The present device also introduces the synergistic effect of the fan 12 and the adsorption head 15. Through the suction generated by the fan 12, the adsorption head 15 can timely adsorb the debris and dust around the lower cavity 2 and send it to the recycling box 13. This design not only ensures the continuous progress of the stamping process, but also maintains the cleanliness and hygiene of the working environment.

[0024] Specifically, in this embodiment, the scheme mainly includes a support base 1; the support base 1 is used to stably support the stamping equipment above. Before stamping the metal sheet, the heating block 10 is first started to preheat the liquid, and then the pump body 6 pumps the preheated liquid into the cooling groove 3. The cooling groove 3 is distributed in an annular shape on the outside of the lower die cavity 2, so as to uniformly preheat the mold and ensure that the metal sheet reaches an ideal temperature state before stamping.

[0025] After preheating, the pump body 6 pumps the preheating liquid back to the corresponding cavity in the box body 4, and then starts to stamp the metal sheet. When the stamping operation is completed, another pump body 6 is responsible for pumping the cooling liquid out of the cooling tank 3 and transporting it to the cavity of another box body 4 through the conduit 7 for circulation. In this way, the cooling liquid can continuously cool the mold to ensure that the workpiece after stamping can be quickly cooled and formed; at the same time, the cooling fan 9 is installed in the reserved groove 8 at the top of the box body 4. Its function is to dissipate the heat of the circulating cooling liquid, effectively preventing the cooling liquid from absorbing too much heat and causing the temperature to rise, thereby maintaining its good cooling effect.

[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, an assembly groove 11 is opened on the outer wall of one side of the support seat 1, and a fan 12 and a recovery box 13 are arranged in the assembly groove 11. The discharge end of the fan 12 is connected to the recovery box 13, and the adsorption end of the fan 12 is connected to a flexible tube 14, and the end of the flexible tube 14 away from the fan 12 is connected to an adsorption head 15.

[0027] In this embodiment, during the stamping process of the metal sheet, a certain amount of debris and impurities will be generated due to the shearing and deformation of the material. When the fan 12 is working, the suction head 15 can be held close to the lower mold cavity 2 so as to accurately absorb and guide the debris or dust and other impurities generated in the lower mold cavity 2. Since the flexible tube 14 has a certain flexibility, it allows the suction head 15 to move freely within a certain range to adapt to different working environments and needs. Once the suction head 15 successfully absorbs the debris or dust, these impurities will be guided into the interior of the fan 12. Subsequently, the fan 12 sends these substances into the recycling box 13 through its discharge end. The design of the recycling box 13 enables the debris and impurities to be effectively collected and stored, which is convenient for subsequent cleaning and processing.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, a support frame 16 for placing the adsorption head 15 is provided at the upper position of the support seat 1 adjacent to the assembly groove 11 .

[0029] In this embodiment, when the fan 12 is not working, the adsorption head 15 can be securely placed on the support frame 16, avoiding damage or loss that may be caused by random placement.

[0030] In a further preferred embodiment of the present invention, Figure 1-2 As shown, guide rods 17 are provided at the four corner positions of the upper surface of the support seat 1, and the same upper mold seat 18 is slidably fitted on the four guide rods 17. A mold head 19 is provided on the bottom side of the upper mold seat 18, and the mold head 19 is pressed together with the lower mold cavity 2 to form a cavity.

[0031] In this embodiment, when stamping is required, the upper die holder 18 moves downward along the guide rod 17, driving the die head 19 to press the lower die cavity 2, thereby forming a closed cavity.

[0032] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a top plate 20 is provided on the side of the four guide rods 17 away from the support seat 1 , a stamping cylinder 21 is provided above the top plate 20 , and an output end of the stamping cylinder 21 passes through one side of the top plate 20 and is connected to the upper die seat 18 .

[0033] In this embodiment, due to the precise and controllable power provided by the stamping cylinder 21, it is possible to ensure that the pressing force and speed between the die head 19 and the lower die cavity 2 are precisely controlled, thereby achieving a high-quality stamping effect.

[0034] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a temperature sensor 22 is disposed on the bottom side of the cooling tank 3 , and an operation screen 23 electrically connected to the temperature sensor 22 is disposed on the outer side of the support seat 1 .

[0035] In this embodiment, the temperature sensor 22 (PT100) senses the temperature changes in the cooling tank 3 and converts them into electrical signals; the operating screen 23 receives these electrical signals and converts them into readable temperature values ​​for display; it is convenient for the staff to adjust the temperature of the cooling tank 3.

[0036] Working principle: First, the support seat 1 firmly supports the stamping equipment above; before the stamping operation begins, the heating block 10 will be started first to preheat the liquid; preheating is to ensure that the metal sheet can reach the ideal temperature state in the subsequent stamping process and improve the stamping effect; then, the pump body 6 pumps the preheated liquid into the cooling groove 3; the cooling groove 3 is distributed in a ring shape on the outside of the lower mold cavity 2. This design allows the mold to be preheated evenly to avoid stamping quality problems caused by uneven temperature; after the preheating is completed, the pump body 6 will pump the preheated liquid back to the corresponding cavity in the box body 4 to prepare for the subsequent stamping operation;

[0037] Subsequently, the stamping operation begins; the stamping cylinder 21 drives the upper die seat 18 to move downward along the guide rod 17, driving the die head 19 to press the lower die cavity 2, thereby forming a closed cavity; in this process, the metal sheet is deformed under the pressing action of the die head 19 and the lower die cavity 2 to obtain the desired shape; due to the shearing and deformation of the material during the stamping process, a certain amount of debris and impurities will be generated; therefore, after the stamping operation is completed, the fan 12 is started, and the suction head 15 can be held close to the lower die cavity 2; since the suction head 15 is connected to the fan 12 through the flexible tube 14, it can move freely within a certain range, thereby accurately absorbing and guiding impurities such as debris or dust generated in the lower die cavity 2; these absorbed impurities are then sent to the recovery box 13 by the fan 12 through its discharge end to achieve effective collection and storage;

[0038] At the same time, in order to maintain the cooling effect of the mold after stamping, another pump body 6 is responsible for extracting the cooling liquid from the cooling tank 3 and transporting it to the cavity of another box body 4 through the conduit 7 for circulation; during the circulation process, the cooling fan 9 is installed in the reserved groove 8 on the top of the box body 4 to dissipate the heat of the circulating cooling liquid to prevent it from absorbing too much heat and causing the temperature to rise, thereby ensuring the cooling effect.
