Description

Technical Field

[0001] This utility model is a multi-channel cooling structure for stainless steel forgings, belonging to the field of forging cooling structures. Background Technology

[0002] In the production and manufacturing of stainless steel forgings, the cooling process is a core step that determines the quality and performance of the forgings. It directly affects not only the uniformity of the internal metallographic structure of the forgings but also their final mechanical properties such as strength and toughness. However, the mainstream traditional cooling methods in the industry mainly employ simple spray cooling or coolant pool immersion cooling. Coolant pool immersion cooling structures typically consist of a large open container filled with a large amount of coolant. During the cooling process, the stainless steel forgings are directly immersed in the coolant pool, relying on natural heat exchange between the coolant and the forgings to achieve cooling. Simple spray cooling structures generally consist of a storage tank, a water pump, spray pipes, and nozzles. During operation, the water pump draws coolant from the storage tank and delivers it to the nozzles through the spray pipes, from which the coolant is sprayed onto the surface of the forgings in a mist or columnar pattern.

[0003] When using a coolant bath for immersion cooling, the lack of precise flow guidance within the coolant bath results in disordered turbulent flow of the coolant, leading to differences in cooling rates across different parts of the forging. This uneven cooling generates significant thermal stress within the forging, easily causing defects such as cracks and deformation. Furthermore, the open structure of the coolant bath results in a large amount of coolant filling areas that are not in contact with the forging. Compared to precise cooling scenarios, this requires a larger volume of coolant, significantly increasing production costs. Simple spray cooling also suffers from blind spots due to the difficulty in precisely controlling the spray angle and flow rate. Moreover, most of the sprayed coolant drips directly, making it difficult to recycle and resulting in serious resource waste. Therefore, designing a multi-channel cooling structure for stainless steel forgings is essential. Utility Model Content

[0006] Furthermore, a circulation pump is provided on one side of the top of the base plate, and the output end of the circulation pump is connected to the distribution pipe through a telescopic conduit. The top of the distribution pipe is evenly provided with liquid outlet pipes, and multiple liquid outlet pipes are alternately threaded with connecting hoses and sealing caps.

[0007] Furthermore, a sludge discharge port is provided at the center of one end of the coolant tank, and the bottom of the sludge discharge port is flush with the top of the filter screen. A servo motor is fixed at the center of the other end of the coolant tank, and a flange is provided at the edge of the top of the coolant tank.

[0008] Furthermore, the multi-channel module includes an outer frame and a channel module, and the channel module is fixed inside the center of the outer frame. The channel module has cooling channels arranged in a matrix in a longitudinal direction. The shape of the cooling channels is adapted to the forging and is slightly larger than the forging. The top of the channel module is lower than the top of the outer frame, and the bottom of the channel module is higher than the bottom of the outer frame. The flange extends into the bottom of the outer frame, and the outer wall of the flange is in contact with the inner wall of the outer frame.

[0009] Furthermore, each of the top covers is fixed with a movable sleeve whose inner diameter matches the outer diameter of the column near the column, and a boss is provided at the bottom of the top cover. The boss is inserted into the top of the inner frame, and the outer wall of the boss fits against the inner wall of the outer frame. The inner wall of the top cover fits against the outer wall of the outer frame.

[0010] Furthermore, a hydraulic telescopic rod is installed at the center of the top of the top plate, and the bottom output end of the hydraulic telescopic rod passes through the top plate and connects to the top cover.

[0011] Furthermore, the mounting assembly includes a slider, a sleeve, a threaded sleeve, and a compression spring. The slider is slidably connected to the slide groove, and a sleeve is fixed to one end of the slider near the distribution pipe. A compression spring is provided inside the sleeve, and the compression spring extends out of the sleeve. A threaded sleeve is connected to one end of the slider near the distribution pipe.

[0012] Furthermore, the distribution assembly includes a main pipe, a threaded pipe, a branch pipe, and a sealing plug. The threaded pipe is integrally connected to the center of the top of the main pipe and is threadedly connected to the connecting hose. A branch pipe is provided at the bottom of the main pipe corresponding to the cooling channel, and a sealing plug with a shape matching the inner wall of the cooling channel is fixed on the outside of the branch pipe. The installation assembly is symmetrically arranged at both ends of the main pipe and is threadedly connected to the end of the main pipe through a threaded sleeve.

[0013] Furthermore, the cleaning assembly includes a lead screw, a connecting plate, and a silicone scraper.

[0014] The beneficial effects of this utility model are:

[0015] 1. The cooling channels in the multi-channel module are longitudinally distributed and are shaped to fit the forgings and are slightly larger than the forgings. Their function is to precisely cool the forgings in the channels. During production, the stainless steel forgings are placed in the cooling channels, and the coolant flows in the channels that fit the shape of the forgings. This allows all parts of the forgings to fully contact the coolant and achieve precise cooling. At the same time, since the cooling channels are only slightly larger than the forgings, unnecessary space for coolant filling is reduced, thereby reducing the amount of coolant used.

[0016] 2. The detachable design of the multi-channel module and distribution components greatly enhances the versatility and flexibility of the cooling structure. Enterprises do not need to equip multiple sets of dedicated cooling equipment for different types of stainless steel forgings, reducing equipment procurement costs. When switching production tasks, the quick replacement of modules and components can significantly shorten equipment adjustment time, improve production efficiency, and meet diverse production needs.

[0017] 3. The output end of the servo motor drives the lead screw to rotate through the pulley mechanism. The lead screw grooves on both sides of the connecting plate are matched with the lead screw. When the lead screw rotates, it drives the connecting plate to move along the lead screw. The silicone scraper at the bottom of the connecting plate cleans the impurities on the filter screen during the movement, preventing impurities from clogging the filter screen, ensuring the cleanliness of the coolant, extending the service life of the coolant, and reducing the amount of manual cleaning work.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1 to 7This utility model provides a technical solution: a multi-channel cooling structure for stainless steel forgings, including a base plate 1, a coolant tank 2 installed at the center of the top of the base plate 1, and a multi-channel module 10 connected to the top of the coolant tank 2. A filter screen 17 is installed at the center of the interior of the coolant tank 2, and a cleaning component 18 is installed inside the coolant tank 2 above the filter screen 17. Columns 5 are installed at the four corners of the top of the base plate 1, and a top plate 8 is installed on the top of the column 5. A top cover 7 is installed below the top plate 8. The top cover 7 has sliding grooves 12 at both ends, and mounting components 11 are evenly arranged in the sliding grooves 12. A distribution component 16 is detachably arranged between the two mounting components 11. A distribution pipe 13 is arranged in the center of the top cover 7, and the distribution pipe 13 is connected to the distribution component 16 through a connecting hose 14. The filter screen 17 and the cleaning component 18 arranged inside the coolant tank 2 work together to effectively intercept impurities, debris and other substances mixed in during the coolant circulation process. The filter screen 17 performs preliminary filtration of the coolant.

[0029] For example, a circulation pump 4 is provided on one side of the top of the base plate 1, and the output end of the circulation pump 4 is connected to the distribution pipe 13 through a telescopic conduit 6. The top of the distribution pipe 13 is uniformly provided with liquid outlet pipes, and multiple liquid outlet pipes are alternately threaded with connecting hoses 14 and sealing caps 15. The circulation pump 4 draws out the coolant from the coolant tank 2 and delivers it to the distribution pipe 13 through the telescopic conduit 6 to ensure that the coolant can continuously and stably circulate in the system. The number and connection position of the connecting hoses 14 and sealing caps 15 can be adjusted according to the number of distribution components 16 that need to be connected.

[0030] For example, a drain port 3 is provided at the center of one end of the coolant tank 2, and the bottom of the drain port 3 is flush with the top of the filter screen 17. A servo motor 19 is fixed at the center of the other end of the coolant tank 2, and a flange 201 is provided at the edge of the top of the coolant tank 2. After the cleaning component 18 pushes the impurities intercepted on the filter screen 17 to the vicinity of the drain port 3, since the drain port 3 is flush with the top of the filter screen 17, the impurities can be smoothly discharged from the coolant tank 2 by their own gravity or with a little external force.

[0031] Please see Figure 6The multi-channel module 10 includes an outer frame 1001 and a channel module 1002, with the channel module 1002 fixed inside the center of the outer frame 1001. Cooling channels 1003 are arranged in a matrix within the channel module 1002. The shape of the cooling channels 1003 is adapted to the forging and slightly larger than the forging. The top of the channel module 1002 is lower than the top of the outer frame 1001, and the bottom of the channel module 1002 is higher than the bottom of the outer frame 1001. A flange 201 extends into the outer frame 1001. The inner bottom of the 01 flange 201 is attached to the inner wall of the outer frame 1001. The cooling channels 1003 distributed longitudinally in the channel module 1002 of the multi-channel module 10 are arranged in a matrix, which enables the coolant to flow quickly and evenly around the forging, achieving all-round cooling of the forging. The flange 201 at the top edge of the coolant tank 2 extends into the inner bottom of the outer frame 1001, and the outer wall of the flange 201 is attached to the inner wall of the outer frame 1001, forming a tight sealing structure.

[0032] Please see Figure 2 and Figure 3 The top cover 7 is fixed with a movable sleeve 701 whose inner diameter matches the outer diameter of the column 5 near the column 5. The bottom of the top cover 7 is provided with a boss 702. The boss 702 is inserted into the top of the inner side of the outer frame 1001, and the outer wall of the boss 702 is in contact with the inner wall of the outer frame 1001. The inner wall of the top cover 7 is in contact with the outer wall of the outer frame 1001. The boss 702 at the bottom of the top cover 7 is inserted into the top of the inner side of the outer frame 1001, and the outer wall of the boss 702 is in contact with the inner wall of the outer frame 1001. At the same time, the inner wall of the top cover 7 is in contact with the outer wall of the outer frame 1001. This multi-seal structure design greatly improves the sealing performance of the cooling system.

[0033] Please see Figure 1 A hydraulic telescopic rod 9 is installed at the center of the top of the top plate 8, and the bottom output end of the hydraulic telescopic rod 9 passes through the top plate 8 and connects to the top cover 7. For stainless steel forgings of different thicknesses and specifications, the height of the top cover 7 can be quickly and accurately adjusted by controlling the extension length of the hydraulic telescopic rod 9, ensuring that the top cover 7 fits tightly with the multi-channel module 10.

[0034] Please see Figure 7The mounting assembly 11 includes a slider 1101, a sleeve 1102, a threaded sleeve 1103, and a compression spring 1104. The slider 1101 is slidably connected to the slide groove 12, and the sleeve 1102 is fixed to one end of the slider 1101 near the distribution pipe 13. The compression spring 1104 is provided inside the sleeve 1102 and extends out of the sleeve 1102. The threaded sleeve 1103 is connected to one end of the slider 1101 near the distribution pipe 13. The slider 1101 in the mounting assembly 11 is slidably connected to the slide groove 12 inside the top cover 7, so that the mounting assembly 11 can move freely in the slide groove 12. This design provides great flexibility for the installation of the distribution assembly 16. The operator can quickly adjust the position of the mounting assembly 11 according to actual needs to adapt to the distribution assembly 16 of different specifications and layouts.

[0035] Please see Figure 7 The distribution assembly 16 includes a main pipe 1601, a threaded pipe 1602, a branch pipe 1603, and a sealing plug 1604. The threaded pipe 1602 is integrally connected to the center of the top of the main pipe 1601, and the threaded pipe 1602 is threadedly connected to the connecting hose 14. The branch pipe 1603 is provided at the bottom of the main pipe 1601 corresponding to the cooling channel 1003, and a sealing plug 1604 with a shape matching the inner wall of the cooling channel 1003 is fixed to the outside of the branch pipe 1603. The mounting assembly 11 is symmetrically arranged on the main pipe 1601. The installation component 11 is threadedly connected to the end of the main pipe 1601 via the threaded sleeve 1103. The design of the main pipe 1601, threaded pipe 1602 and branch pipe 1603 in the distribution component 16 realizes the precise distribution of coolant. The threaded pipe 1602 is threadedly connected to the connecting hose 14 to ensure that the coolant can be stably delivered from the distribution pipe 13 to the main pipe 1601. The branch pipe 1603 at the bottom of the main pipe 1601 corresponding to the cooling channel 1003 can evenly distribute the coolant to each cooling channel 1003.

[0036] Please see Figure 4 and Figure 5The cleaning assembly 18 includes a lead screw 20, a connecting plate 22, and a silicone scraper 23. Lead screws 20 are rotatably connected to both sides of the coolant tank 2 above the filter screen 17, and a connecting plate 22 connects the two lead screws 20. A silicone scraper 23 is installed at the bottom of the connecting plate 22, and the bottom of the silicone scraper 23 contacts the upper surface of the filter screen 17. The output end of the servo motor 19 is connected to the lead screw 20 via a pulley mechanism 21. Both sides of the connecting plate 22 have lead screw grooves 2201 adapted to the lead screw 20. The pulley mechanism 21 includes two driven pulleys connected to the lead screw 20, a driving pulley connected to the output end of the servo motor 19, and a transmission chain for transmission. The cleaning component 18 drives the pulley mechanism 21 through the servo motor 19, which drives the lead screw 20 to rotate, thereby causing the silicone scraper 23 at the bottom of the connecting plate 22 to move back and forth on the upper surface of the filter screen 17. This automated cleaning method can remove the impurities intercepted on the filter screen 17 in a timely manner, prevent the accumulation of impurities from clogging the filter screen 17, and ensure the normal flow of coolant and the filtration effect.

[0037] Detailed implementation: In use, the circulating pump 4 drives the coolant to flow into the multi-channel module 10 through the distribution pipe 13 and other parts. The cleaning component 18 maintains the cleanliness of the coolant, and the sealing structure ensures the stability of the system. The circulating pump 4 draws coolant from the coolant tank 2 and sends it to the distribution pipe 13 through the retractable conduit 6. The top outlet pipe of the distribution pipe 13 is connected to the threaded pipe 1602 of the distribution assembly 16 via the connecting hose 14. The coolant flows into the main pipe 1601, then through the branch pipe 1603 into the cooling channel 1003 of the multi-channel module 10 to cool the forgings, and finally flows back to the coolant tank 2. The cooling channels 1003 in the channel module 1002 of the multi-channel module 10 are arranged in a matrix. The flange 201 of the coolant tank 2 and the boss 702 of the top cover 7 are tightly fitted with the outer frame 1001. Multiple seals ensure that the coolant does not leak out, achieving efficient cooling. The servo motor 19 drives the lead screw 20 to rotate through the pulley mechanism 21, causing the silicone scraper 23 at the bottom of the connecting plate 22 to move on the surface of the filter screen 17, pushing impurities to the discharge port 3 for discharge, maintaining the cleanliness of the coolant.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
