Description

Technical Field

[0001] This invention belongs to the field of circulating cooling technology, and particularly relates to a circulating cooling device for stamping automotive parts. Background Technology

[0002] During the stamping process of automotive parts, a large amount of heat is generated between the die and the sheet metal due to high-speed friction and plastic deformation of the metal. If the heat cannot be dissipated in time, the die temperature will rise sharply, causing a series of problems such as thermal fatigue cracking of the die, surface scratches on the parts, and decreased stamping accuracy. Therefore, a circulating cooling device is usually equipped in the stamping process to carry away excess heat by supplying coolant into the die, thereby maintaining the die operating temperature within a reasonable range.

[0003] Currently, most common automotive parts stamping circulating cooling systems consist of a circulating pump, a cooling tank, and piping. The basic workflow is as follows: the circulating pump delivers coolant to the cooling channels of the stamping die; the coolant absorbs heat from the die and then flows back to the cooling tank; after natural cooling or air cooling, it is then pumped back to the die, thus achieving circulating cooling. Some more advanced cooling systems also add a compressor and cooling coils to the cooling tank, using refrigerant to exchange heat with the circulating fluid to achieve forced cooling, significantly improving cooling efficiency.

[0004] However, the existing circulating cooling devices still have the following technical defects in actual use: due to the metal chips, oxide scale and other solid particles generated by the friction of the mold during the stamping process, they will flow back into the cooling tank with the circulating liquid. If these impurities are suspended or deposited in the circulating liquid for a long time, they will easily cause blockage of the cooling pipes and the micro channels inside the mold. At the same time, after the impurities re-enter the mold with the circulating liquid, they will aggravate the friction between the mold and the sheet metal, accelerate the wear of the mold, and seriously affect the surface quality of the stamped parts and the service life of the mold.

[0005] To address the aforementioned issues, there is an urgent need to design a stamping circulating cooling device capable of efficiently centrifugally filtering the coolant during the circulating cooling process, in order to overcome the shortcomings of existing technologies.

[0008] Preferably, a compressor is fixedly installed on one side of the outer surface of the circulation tank, and a cooling pipe is provided on the bottom surface of the inner cavity of the circulation tank. The cooling pipe is located below the suction pipe and is connected to the compressor. After the compressor is running, it cools the circulating liquid through the cooling pipe.

[0009] Preferably, a suction tube is fixedly connected to the bottom surface of the filter cylinder. The suction tube extends downward in the vertical direction and forms a rigid connection with the filter cylinder. The suction tube rotates synchronously with the filter cylinder. A stirring rod is fixedly provided on the outer circumferential surface of the suction tube. The stirring rod is evenly distributed along the axial and circumferential directions of the suction tube in the lower outer circumferential area of ​​the filter cylinder.

[0010] Preferably, two nozzles are fixedly installed on both sides of the bottom surface of the support frame, the two opposite nozzles extend downward in the vertical direction, and the ends of the two opposite nozzles are fixedly connected with collars, the axis of the collars coinciding with the axis of the suction pipe.

[0011] Preferably, the top of the collar has a rotating hole extending axially, the rotating hole is fitted onto the outer circumferential surface of the suction tube, the collar and the inside of the nozzle have a common spray chamber, and the nozzle has a spray hole on one side surface facing the outer circumferential surface of the filter cylinder, the spray hole being connected to the spray chamber.

[0012] Preferably, the inner annular wall of the rotating hole is provided with a second through hole, which is connected to the spray chamber; the bottom surface of the suction tube is provided with a suction hole along the axial direction, the inner cavity of the suction hole is provided with an impeller, the impeller is fixedly connected to the suction tube and rotates synchronously at high speed with the suction tube, and the outer peripheral surface of the suction tube is provided with a first through hole, which is aligned with and connected to the second through hole.

[0013] Preferably, the opening position of the first through hole and the opening end of the second through hole are at the same horizontal level in the radial direction. Multiple rollers are provided, and the multiple rollers are evenly distributed along the circumferential direction of the bottom of the filter cylinder. The outer edge of the bottom of the filter cylinder forms a rolling contact fit with the outer circumferential surface of the rollers.

[0014] Preferably, the filter cylinder has a cylindrical structure with an open top and a closed bottom. Filter holes are provided on the outer circumferential surface of the filter cylinder. The clear liquid after centrifugal filtration through the filter cylinder is thrown out through the filter holes to the outside of the filter cylinder and collects at the bottom of the inner cavity of the circulation tank.

[0015] Preferably, the cooling pipe has a serpentine or spiral coiled structure, and the refrigerant inlet and outlet ends of the cooling pipe are respectively connected to the corresponding interfaces of the compressor through pipelines.

[0016] Preferably, the motor frame is fixed to the top wall of the circulation box by profile welding or bolt connection, and the connecting rod extends downward in the vertical direction, passes through the feed port and extends into the interior of the circulation box.

[0017] The automotive parts stamping circulating cooling device of the present invention has the following advantages: 1. A circulating cooling device for stamping automotive parts. This application uses a motor-driven connecting rod to rotate a filter cylinder at high speed. Centrifugal force is used to efficiently remove metal debris, scale, and other solid particulate impurities from the circulating fluid and trap them on the inner wall of the filter cylinder. The purified liquid is discharged through the filter holes and collects at the bottom of the circulating tank. Compared with traditional static filter filtration, the above-mentioned centrifugal filtration method has the advantages of high filtration efficiency, thorough impurity separation, and less likelihood of overall clogging. It can effectively prevent impurities from re-entering the stamping die and cooling pipes with the circulating fluid, significantly improving the purity of the circulating coolant and extending the service life of the die and pipes.

[0018] 2. A circulating cooling device for stamping automotive parts. This application utilizes a compressor in conjunction with a cooling pipe located at the bottom of the circulating tank to directly cool the circulating fluid. Simultaneously, a filter cartridge drives the suction pipe and stirring rod to rotate synchronously, continuously agitating the circulating fluid inside the tank and forcibly breaking up temperature stratification that occurs during the cooling process. This structure highly integrates the stirring and cooling functions, eliminating the need for a separate stirring drive source. It effectively improves the uniformity of the overall temperature field of the circulating fluid, enhances the convective heat transfer efficiency between the circulating fluid and the cooling pipe, thereby comprehensively improving the cooling effect and preventing localized high temperatures from affecting the cooling uniformity of the stamping die.

[0019] 3. A circulating cooling device for stamping automotive parts. This application involves fixing a nozzle and a collar to the bottom surface of a support frame, and creating a second through-hole in the inner wall of the collar. This through-hole engages with a first through-hole on the suction pipe and an impeller within the suction hole. When the filter cartridge rotates, it synchronously drives the impeller to rotate, generating suction force. This forces the clean circulating fluid in the circulation tank through the suction hole, the first through-hole, the second through-hole, and the spray chamber, before spraying it from the nozzle onto the outer circumference of the filter cartridge. Because the filter cartridge rotates continuously while the nozzle remains relatively stationary, the nozzle can continuously change its spray and flushing position along the circumference of the filter cartridge, achieving dynamic and uniform reverse flushing. This promptly removes impurities that are blocked or attached to the filter holes, effectively preventing filter hole blockage and ensuring the filter cartridge remains in a good permeable state for a long time, significantly extending the maintenance cycle and service life of the filter cartridge.

[0023] To better understand the purpose, structure, and function of this invention, the following detailed description of a stamping circulation cooling device for automotive parts, in conjunction with the accompanying drawings, is provided.

[0024] like Figures 1 to 3 As shown, this invention provides a stamping circulation cooling device for automotive parts, which mainly includes a circulation tank 1 and a circulation pump 3 disposed on one side above the circulation tank 1. The circulation tank 1 is constructed with an internal hollow cavity structure to store and contain circulating coolant, and to provide space for subsequent filtration, cooling, and circulation processes. The circulation pump 3 is fixedly installed on one side above the circulation tank 1. This circulation pump 3 serves as the core power source for the coolant circulation flow, and its bottom has a suction pipe 32 extending into the inner cavity of the circulation tank 1. The suction pipe 32 is used to draw the cooled circulating coolant from the circulation tank 1 into the circulation pump 3, and discharges the cooled circulating coolant outward through a circulation port 33 located at the output end of the circulation pump 3. A circulation pipe 31 is tightly fitted onto the outer circumference of the circulation port 33. One end of the circulation pipe 31 forms a sealed connection with the circulation port 33, and its end extends to the inlet 11 opened on one side above the circulation tank 1. Through the above-mentioned pipeline circulation layout, the circulating fluid can be discharged from the circulating pump 3, transported through the circulating pipe 31, and returned to the inside of the circulating tank 1 through the feed port 11, thereby realizing the closed-loop circulation of the coolant.

[0025] Furthermore, a motor frame 12 is fixedly installed at the opening above the feed inlet 11. This motor frame 12 is fixed to the top wall of the circulation tank 1 using profile welding or bolt connection to provide a stable support foundation. A motor 2 is fixedly installed above the motor frame 12. The rigid support of the motor frame 12 ensures that the motor 2 remains in a fixed position during long-term high-speed operation, effectively preventing swaying or displacement caused by vibration or torque reaction forces, thus ensuring the smoothness and reliability of power transmission. A load-bearing frame 13 is fixedly installed at a radially relative position to the feed inlet 11, inside the lower part of the circulation tank 1. Both ends of the load-bearing frame 13 are fixedly connected to the inner wall of the circulation tank 1, thus constructing a support beam structure spanning the inner cavity of the circulation tank 1 to support the subsequent rotating filter assembly. Multiple rollers 131 are rotatably installed above the load-bearing frame 13. These rollers 131 are evenly distributed along the circumference of the bottom of the filter cylinder 22, forming a rolling support system for the filter cylinder 22. A filter cylinder 22 capable of rotation is installed above the roller 131. The filter cylinder 22 has a cylindrical structure with an open top and a closed bottom, and its outer edge forms a rolling contact with the outer surface of the roller 131. Supported and guided by the roller 131, the filter cylinder 22 can rotate smoothly and at high speed with relatively low frictional resistance, thus ensuring the stability and continuity of the centrifugal filtration process. A connecting rod 21 is fixedly connected downwards to the power output end of the motor 2. This connecting rod 21 extends vertically downwards, and its end passes through the feed inlet 11 and extends into the circulation tank 1, forming a fixed connection with the center of the bottom surface of the filter cylinder 22's inner cavity. Therefore, when the motor 2 is powered on, its power output end drives the connecting rod 21 to rotate synchronously, thereby transmitting the rotational torque to the filter cylinder 22 through the connecting rod 21, driving the filter cylinder 22 to rotate at a predetermined high speed. As the filter cylinder 22 rotates at high speed, the circulating liquid flowing into and falling into the filter cylinder 22 through the feed inlet 11 is accelerated under the action of centrifugal force. Metal scraps, oxide scale, and other solid particle impurities carried in the circulating liquid, due to their greater density than the liquid, are thrown towards the inner wall of the filter cylinder 22 in the centrifugal force field and intercepted by the filter holes of the filter cylinder 22, thus adhering to the inner wall surface of the filter cylinder 22. The purified liquid is then thrown out through the filter holes to the outside of the filter cylinder 22 and collects at the bottom of the inner cavity of the circulation tank 1. Through the above centrifugal filtration mechanism, solid impurities in the circulating liquid can be effectively separated and collected, preventing impurities from re-entering the stamping die and cooling pipes with the circulating liquid, thereby significantly improving the purity and stability of the subsequent circulating cooling effect and extending the service life of the die and pipes.

[0026] like Figures 3 to 4As shown, a compressor 4 is fixedly installed on one side of the outer surface of the circulation chamber 1. This compressor 4 provides refrigeration compression power to the cooling system. A cooling pipe 41 is arranged on the bottom surface of the inner cavity of the circulation chamber 1. The cooling pipe 41 preferably adopts a serpentine or spiral coiled copper or aluminum coil structure to increase the heat exchange area and improve heat exchange efficiency. The cooling pipe 41 is located below the suction pipe 32, and the refrigerant inlet and outlet ends of the cooling pipe 41 are connected to the corresponding interfaces of the compressor 4 through pipelines, forming a complete refrigerant circulation loop. During the circulation cooling operation, the compressor 4 starts running, compressing the refrigerant into a high-temperature, high-pressure gas, which is then cooled by the condenser. Subsequently, it passes through a throttling device to become a low-temperature, low-pressure liquid and enters the cooling pipe 41. During the flow of the low-temperature refrigerant within the cooling pipe 41, it exchanges heat with the circulating liquid at the bottom of the inner cavity of the circulation chamber 1, absorbing heat from the circulating liquid and lowering its temperature. After cooling, the low-temperature circulating liquid gathers at the bottom of the inner cavity of the circulation tank 1, which is located at the lower inlet of the suction pipe 32. This allows it to be drawn in a timely and efficient manner by the suction pipe 32 and then transported back to the cooling channel of the stamping die by the circulation pump 3, so as to achieve a continuous and stable cooling effect.

[0027] like Figures 5 to 6 As shown, a suction pipe 23 is fixedly connected to the center of the bottom surface of the filter cylinder 22. The suction pipe 23 extends vertically downwards and forms a rigid connection with the filter cylinder 22, thus allowing it to rotate synchronously with the filter cylinder 22. Several stirring rods 232 are also fixedly arranged on the outer circumferential surface of the suction pipe 23. These stirring rods 232 are evenly distributed along the axial and circumferential directions of the suction pipe 23 and are located in the lower outer circumferential region of the filter cylinder 22. Because the stirring rods 232 are fixedly connected to the suction pipe 23, when the filter cylinder 22 rotates at high speed, the filter cylinder 22 can synchronously drive the suction pipe 23 at the bottom to rotate, and the suction pipe 23 further drives the stirring rods 232 on its outer circumferential surface to rotate and agitate below the circulating liquid surface in the circulation tank 1. The forced convection generated by the continuous rotation of the stirring rod 232 can uniformly stir the circulating liquid inside the circulation tank 1, break the temperature stratification phenomenon of the circulating liquid during the cooling process, avoid the generation of local overcooled or overheated areas, thereby significantly improving the uniformity of the overall temperature field of the circulating liquid. At the same time, it enhances the convective heat transfer coefficient between the circulating liquid and the cooling pipe 41, thereby comprehensively improving the overall cooling effect and effectively preventing the uniformity of the stamping die from being affected by local high temperature.

[0028] like Figures 5 to 9As shown, nozzles 14 are fixedly installed on both sides of the bottom surface of the support frame 13. The nozzles 14 extend vertically downwards and are arranged opposite each other. A collar 142 is fixedly connected to the end of each of the two opposing nozzles 14. The collar 142 has a circular structure, and its axis coincides with the axis of the suction pipe 23. A rotating hole 143 is provided at the top of the collar 142 and extends downwards along its axial direction. This rotating hole 143 is a through-hole structure, and its inner diameter is larger than the outer diameter of the suction pipe 23. This allows the collar 142 to be fitted onto the outer circumference of the suction pipe 23, maintaining a small gap in a rotational fit. This allows the suction pipe 23 to rotate freely within the rotating hole 143 without interfering with the collar 142. Simultaneously, the collar 142 and the nozzles 14 are internally connected and share a common spray chamber 144, which serves as a flow channel for the washing fluid. On the surface of the nozzle 14 facing the outer peripheral surface of the filter cylinder 22, a plurality of uniformly arranged nozzle holes 141 are provided. These nozzle holes 141 are connected to the spray chamber 144 and are used to guide the sprayed fluid to the outer wall surface of the filter cylinder 22.

[0029] Furthermore, a through hole 145 is formed on the inner annular wall of the rotating hole 143, extending from the surface of the inner annular wall into the collar 142. One end of the through hole 145 opens into the inner annular wall of the rotating hole 143, and the other end communicates with the interior of the injection chamber 144, thereby establishing a complete fluid channel from the interior of the rotating hole 143 to the injection hole 141. A suction hole 231 is formed axially upward from the center of the bottom surface of the suction pipe 23. The suction hole 231 is a blind hole structure with a certain depth and capacity. An impeller 233 is fixedly installed at the bottom of the inner cavity of the suction hole 231. The impeller 233 adopts a centrifugal or axial flow blade structure and is fixedly connected to the suction pipe 23, so the impeller 233 can rotate at high speed together with the suction pipe 23. A through hole 234 is provided on the outer circumferential surface of the suction tube 23, at a position opposite to the inner annular wall of the rotating hole 143 of the collar 142. The through hole 234 is arranged radially along the suction tube 23, and one end is connected to the interior of the suction hole 231. When the suction tube 23 is installed through the rotating hole 143 of the collar 142, the opening position of the through hole 234 is exactly at the same horizontal level radially as the opening end of the through hole 145, thereby aligning the through hole 234 and the through hole 145 and forming fluid communication.

[0030] Based on the above structure, when the motor 2 drives the filter cartridge 22 to rotate at high speed, since the filter cartridge 22 is fixedly connected to the suction pipe 23, the suction pipe 23 will drive the impeller 233 in its bottom inner cavity to rotate synchronously at high speed. During the high-speed rotation, the impeller 233 generates centrifugal suction force, which causes the clean circulating liquid that has been filtered inside the circulation tank 1 to be continuously drawn into the suction hole 231 and flow upward along the suction hole 231. When the suction liquid reaches the height of the first through hole 234, the fluid flows through the first through hole 234 and the corresponding through hole 2 145 in sequence, and then enters the spray chamber 144 inside the collar 142 and the nozzle 14. Finally, under the guidance of the spray chamber 144, it is sprayed outward at high speed from the spray hole 141 opened on the surface of the nozzle 14 and accurately sprayed onto the outer circumferential surface of the filter cartridge 22. Because the filter cartridge 22 rotates continuously under the drive of the motor 2, while the nozzle 14 and its end collar 142 are fixedly installed on the support frame 13 and remain relatively stationary, the nozzle 141 can continuously change its spraying position along the circumference of the filter cartridge 22 while the filter cartridge 22 rotates, achieving dynamic, uniform, and comprehensive spraying coverage. Through the above-mentioned spraying mechanism, the high-pressure sprayed circulating liquid can backwash and peel off the impurities that are blocked or attached to the filter holes on the outer circumference of the filter cartridge 22, promptly removing the accumulated impurities on the outer wall and inside the filter holes of the filter cartridge 22. This provides continuous and uniform unblocking and cleaning of the filter cartridge 22, effectively preventing filter hole blockage caused by impurity accumulation, ensuring that the filter cartridge 22 is in a good permeable state for a long time, thereby maintaining a stable and efficient filtration effect and significantly extending the maintenance cycle and service life of the filter cartridge 22.

[0031] The working principle of a stamping circulation cooling device for automotive parts: The circulation pump 3 operates, drawing in the low-temperature circulating liquid from the bottom of the circulation tank 1 through the suction pipe 32. The liquid is then transported from the circulation port 33 to the inlet 11 via the circulation pipe 31, and falls into the filter cylinder 22. The motor 2 drives the connecting rod 21 to rotate the filter cylinder 22 at high speed. Under centrifugal force, impurities are thrown against the inner wall of the filter cylinder 22 and trapped, while the clean liquid passes through the filter holes and collects at the bottom of the circulation tank 1. The compressor 4 operates to cool the circulating liquid through the cooling pipe 41. Simultaneously, the filter cylinder 22 drives the suction pipe 23 and the stirring rod 232 to rotate synchronously, agitating the circulating liquid to create a uniform temperature field. The impeller 233 inside the suction pipe 23 generates suction force as it rotates, sending the clean circulating liquid through the suction hole 231, through hole one 234, and through hole two 145 into the spray chamber 144. Finally, it is sprayed from the spray hole 141 onto the outer circumference of the rotating filter cylinder 22, achieving dynamic reverse flushing and preventing filter clogging. This cycle repeats continuously, achieving stable operation of cooling, filtration, and self-cleaning.
