Description

Technical Field

[0001] This invention relates to the field of forging production equipment technology, specifically to a cooling roller line for forgings. Background Technology

[0002] In the cooling process after hot forming of forgings, the cooling rate and uniformity directly affect the internal structure and mechanical properties of the product. Currently, online cooling of forgings mainly adopts methods such as natural air cooling, forced air cooling, immersion cooling, or single spray cooling.

[0003] Natural air cooling has a large footprint and low cooling efficiency; forced air cooling has limited cooling capacity for thick-walled or high-temperature forgings and can easily lead to excessive temperature differences between the surface and the core; although water immersion cooling is rapid, the cooling intensity is difficult to control precisely, which can easily cause forgings to crack, deform or have uneven hardness, and generate a large amount of wastewater; simple spray or mist cooling often causes a large amount of water mist to escape into the workshop, and the accumulation of hot and humid air worsens the working environment, while also affecting the evaporative cooling effect.

[0004] In addition, existing roller conveyor cooling lines rely heavily on manual labor or simple flip-plate mechanisms for feeding, lacking reliable detection and interlocking, resulting in inaccurate feeding positioning and affecting the consistency of subsequent cooling. After long-term use, the roller surface is prone to the adhesion and accumulation of impurities such as oxide scale and oil stains, which not only reduces heat transfer efficiency but also hinders the smooth conveying of forgings. Routine cleaning requires manual scraping after machine shutdown, which is labor-intensive and affects production capacity. Therefore, we propose a wind-mist cooling roller line for forging cooling.

[0036] This invention provides a cooling roller production line for forgings using a mist cooling system. It offers the following advantages:

[0037] 1. A relatively enclosed cooling channel is formed by the fan shroud and the frame, and an axial flow fan blowing downwards and atomizing nozzles spraying evenly from above and both sides are configured. Combined with a water ring vacuum negative pressure station to continuously extract the hot and humid gas in the fan shroud, the evaporative cooling effect is greatly enhanced, and the forgings are cooled quickly and evenly. At the same time, water mist overflow is suppressed from the source, and the workshop working environment is significantly improved.

[0038] 2. The flipping and pushing device integrates a material shortage detection component and a position sensor. Through the sequential interlocking of the flipping cylinder and the feeding side pushing cylinder, the forgings from the previous process can be automatically and smoothly flipped onto the roller conveyor surface and pushed to the conveyor center line, eliminating the safety hazards and positioning deviations of manual feeding and improving the automation level and cycle stability of the entire line.

[0039] 3. The conveyor roller adopts a combination structure of built-in sector groove, sector plate and ring. The roller itself rotates and drives the sector plate to rub intermittently through an incomplete gear pair and eccentric push rod. This causes the ring to move relative to the annular groove on the roller surface, automatically rubbing off the oxide scale and other impurities attached to the surface. It can effectively prevent the accumulation and blockage of impurities without the need for additional power, ensure continuous and uniform contact between cooling water and forgings, and reduce downtime for cleaning.

[0040] 4. The water tank is equipped with a water guide plate that is higher in the middle and lower on both sides, which guides the spray water carrying oxide scale to both sides. Impurities are intercepted by a detachable filter plate, and a cleaning port is provided for easy and quick cleaning. With the layered discharge of overflow port and sewage outlet, the upper clean water and the bottom sediment can be effectively separated. At the same time, the bag filter provides finely filtered clean water for the atomizing nozzles, and the cleaning pipeline uses up-and-down tilted nozzles to automatically rinse the lower surface of the roller and the upper surface of the water guide plate, which significantly improves the cleanliness of the circulating water, extends the water use cycle, and achieves water conservation and emission reduction.

[0041] 5. The end of the conveyor drum is equipped with a conical water-cutting eave and a water baffle, and an annular water guide groove is opened on the drum. This can intercept the water flowing along the axis and guide it back to the storage tank, effectively preventing water from entering the bearings and other transmission components, ensuring long-term stable operation of the equipment and reducing the failure rate.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] like Figures 1 to 11 As shown, the present invention provides a cooling roller conveyor line for forgings, mainly comprising a cooling roller conveyor line, a tilting and pushing device, a non-powered roller chute, and a water pump filtration system. One end of the cooling roller conveyor line serves as the inlet end, and the other end as the outlet end. The tilting and pushing device is arranged at the inlet end, and the non-powered roller chute is arranged at the outlet end. The water pump filtration system is arranged beside the cooling roller conveyor line and connected to the cooling roller conveyor line through pipelines, providing circulating water for cooling and cleaning. Simultaneously, a water ring vacuum negative pressure station 5 is configured near the inlet end, and the water ring vacuum negative pressure station 5 is connected to the air hood 14 through a suction pipe 51. An inlet temperature measuring element 6 and an outlet temperature measuring element 7 are respectively installed at the inlet end and the outlet end. The drive motor 12, axial flow fan 15, inlet temperature measuring element 6, and outlet temperature measuring element 7 are all electrically connected to the control system.

[0061] The air-cooled roller conveyor line includes a frame 11, a drive motor 12, a roller assembly 13, and an air hood 14 covering the roller assembly 13. The drive motor 12 is mounted on the frame 11 and drives each roller in the roller assembly 13 to rotate synchronously via chain or belt drive, achieving horizontal conveying of the forgings. The air hood 14 covers the roller assembly 13 and has multiple axial flow fans 15 installed sequentially along the conveying direction. The axial flow fans 15 blow air downwards to accelerate airflow over the forging surface. Inside the air hood 14, above the roller assembly 13, is a spray assembly 16 with several atomizing nozzles distributed at different positions within the air hood 14, enabling uniform water mist spraying of the passing forgings from above and both sides. A relatively closed cooling channel is formed between the fan shroud 14 and the frame 11. The water ring vacuum negative pressure station 5 is connected to the internal space of the fan shroud 14 through the suction pipe 51. When working, it extracts the hot and humid gas inside the fan shroud 14, which not only enhances the evaporative cooling effect but also prevents water mist from overflowing and improves the workshop environment.

[0062] A flipping and pushing device is installed at the feed end of the air-cooled roller conveyor line to smoothly flip the forgings from the previous process onto the roller line. This device includes a mounting base 21, a receiving plate 22, a flipping cylinder 23, a loading-side push cylinder 24, and a position detection mechanism. The mounting base 21 is fixed to the side of the frame 11. One side of the receiving plate 22 is hinged to the mounting base 21. The cylinder body of the flipping cylinder 23 is hinged to the mounting base 21, and its piston rod end is connected to the bottom of the receiving plate 22. The piston rod extension and retraction drives the receiving plate 22 to flip around the hinge point. The loading-side push cylinder 24 is installed on one side of the receiving plate 22 and is used to push the flipped forgings laterally onto the conveying surface of the roller assembly 13. The position detection mechanism includes a material absence detection component 251 and a position sensor 252. The material absence detection component 251 is used to detect whether there is a forging on the receiving plate 22, and the position sensor 252 is used to detect whether the flipping angle of the receiving plate 22 is in place, thereby ensuring reliable interlocking of the flipping and pushing actions.

[0063] A non-powered roller conveyor is connected to the discharge end of the air-cooled roller conveyor line. This conveyor includes an inclined slide plate 31 and an inclined roller conveyor section 32 connected to the end of the slide plate 31. The roller conveyor section 32 is composed of multiple discharge rollers 33 arranged in a row. After the cooled forgings are removed from the roller conveyor line, they slide down along the roller conveyor section 32 and the slide plate 31, where workers can retrieve the parts or proceed to the next process.

[0064] A lifting mechanism and a discharge-side push cylinder 18 are also installed on the discharge end frame 11 to lift the forgings arriving at the discharge end from the roller assembly 13 and push them laterally into the unpowered roller slide. The lifting mechanism includes a base plate 171, which is fixed to the frame 11. Multiple telescopic columns 172 are installed on the top of the base plate 171, and the tops of the multiple telescopic columns 172 jointly support the top plate 173. Multiple lifting plates 174 are fixed on the top plate 173, and each lifting plate 174 extends upward into the gap between adjacent rollers in the roller assembly 13. A strip groove 175 is opened on the base plate 171, and a lifting cylinder 176 is installed at the bottom of the base plate 171. The output end of the lifting cylinder 176 is connected to a push plate 177, and the top of the push plate 177 has an arc-shaped structure. A lifting wheel 178 is rotatably connected to the bottom of the top plate 173, and the top of the push plate 177 extends through the strip groove 175 and abuts against the bottom of the lifting wheel 178. When the piston rod of the lifting cylinder 176 extends, the arc-shaped top of the push plate 177 pushes the lifting wheel 178, causing the top plate 173 to rise vertically along the telescopic column 172, and the lifting plate 174 then pushes the forging away from the roller surface; subsequently, the unloading side push cylinder 18 is activated, pushing the forging laterally onto the roller conveyor section 32.

[0065] The water pump filtration system includes a centrifugal pump 41, a bag filter 44, and related piping. The input end of the centrifugal pump 41 is connected to the water storage tank 113 inside the frame 11 via a water inlet pipe 42, and the output end is connected to the input end of the bag filter 44 via a water pump outlet pipe 43. The output end of the bag filter 44 is divided into two paths: one is an atomizing water inlet pipe 45, and the other is a cleaning water inlet pipe 46. The fan shroud 14 is provided with a spray inlet 111 connected to the atomizing water inlet pipe 45. The spray inlet 111 is connected to the spray assembly 16, supplying filtered clean water to the atomizing nozzles. The frame 11 is provided with a cleaning inlet 112 connected to the cleaning water inlet pipe 46.

[0066] A water storage tank 113 is located below the roller assembly 13 inside the frame 11 to collect water that falls after spraying. A water guide plate 114 is installed inside the water storage tank 113, with the middle of the guide plate 114 higher than the sides, forming a guide slope that is high in the middle and low on both sides, directing the water flow to both sides. Removable filter plates 115 are installed between the two ends of the guide plate 114 and the side walls of the water storage tank 113. A cleaning port 116 is provided on the side walls of the water storage tank 113 for removing and installing the filter plates 115 to clean intercepted scale and other impurities. The water storage tank 113 also has an overflow port 117 and a drain port 118. The relative height of the overflow port 117 is higher than that of the drain port 118. The cleaner water at the top can flow back or be discharged through the overflow port 117, while the wastewater deposited at the bottom can be periodically discharged through the drain port 118.

[0067] A cleaning pipe 119 is installed inside the water storage tank 113 and above the water guide plate 114, and the cleaning pipe 119 is connected to the cleaning inlet 112. Several inclined cleaning nozzles are installed on both the upper and lower sides of the cleaning pipe 119, which can spray cleaning water onto the lower surface of the roller assembly 13 and the upper surface of the water guide plate 114 to promptly wash away the oxide scale and oil stains attached to the roller and the water guide plate 114, ensuring the cleanliness of the circulating water.

[0068] The roller assembly 13 consists of multiple parallel conveyor rollers 100. For example... Figures 12 to 16 As shown, each conveying roller 100 has a sector-shaped groove 101 axially formed inside, and multiple annular grooves are equidistantly formed on the outer wall of the conveying roller 100, which communicate with the sector-shaped groove 101. A sector-shaped plate 102 is slidably connected inside the sector-shaped groove 101, and multiple rings 103 are equidistantly fixed on the outer wall of the sector-shaped plate 102. The rings 103 are correspondingly arranged in each annular groove, and the outer peripheral wall of the rings 103 is flush with the outer peripheral wall of the conveying roller 100, forming a complete cylindrical conveying surface. A spring 104 connected to the sector-shaped plate 102 is provided inside the sector-shaped groove 101, and the spring 104 is used to keep the sector-shaped plate 102 in its initial position. Incomplete gears 105 are symmetrically fixed at both ends of the conveying roller 100. The toothed part of the incomplete gear 105 meshes with the driven gear 106, and a push rod 107 is eccentrically arranged on one side of the driven gear 106. The end of the sector plate 102 extends out of the sector groove 101 and can engage with the push rod 107. When the conveying roller 100 rotates, the incomplete gear 105 intermittently drives the driven gear 106 to rotate, and the push rod 107 rotates with the driven gear 106, intermittently pushing the sector plate 102 to slide along the sector groove 101, causing relative movement between the ring 103 and the annular groove, thereby rubbing off the oxide scale and other impurities attached to the roller surface, preventing blockage, and ensuring that the cooling water contacts the forgings evenly.

[0069] The air-cooled roller conveyor is also equipped with a pair of baffles 108, which are respectively installed over both ends of the conveyor roller 100. Each end of the conveyor roller 100 is provided with a water-cutting eave 109, which is conical in shape. Its outer edge abuts against the corresponding baffle 108, preventing water from overflowing along the roller axis to both ends. At both ends of the conveyor roller 100, near the water-cutting eaves 109, annular water guide grooves 110 are provided. Water entering the ends is guided along the water-cutting eaves 109 into the water guide grooves 110 and drips back into the storage tank 113, preventing water from entering the bearings and other transmission components.

[0070] During operation, the forging from the previous process is fed onto the receiving plate 22. After the material presence / absence detection component 251 detects the forging, the tilting cylinder 23 drives the receiving plate 22 to tilt upwards, tilting the forging onto the feed end of the roller assembly 13. Subsequently, the feeding side push cylinder 24 pushes the forging upright, positioning it on the conveying center line. The drive motor 12 drives the roller assembly 13 to rotate, moving the forging forward. The inlet temperature measuring component 6 detects the initial temperature of the forging, and the control system automatically adjusts the speed of the drive motor 12 and the speed of the axial flow fan 15 according to preset cooling parameters. The centrifugal pump 41 draws water from the water storage tank 113, filters it through the bag filter 44, and then enters the spray assembly 16 through the atomizing water inlet pipe 45. Water mist is sprayed onto the surface of the forging from the atomizing nozzles, while the axial flow fan 15 blows air downwards simultaneously. The water mist and forced air cooling work together to achieve rapid and uniform cooling; the water ring vacuum negative pressure station 5 continuously extracts hot and humid air to enhance heat exchange. Rinse water and condensate fall onto the guide plate 114, are filtered by the guide plate and filter plate 115, and then flow back to the storage tank 113 for recycling. When the forging reaches the discharge end, the outlet temperature sensor 7 detects the final temperature of the forging. If the cooling requirements are met, the lifting cylinder 176 is activated, the lifting plate 174 lifts the forging, and the unloading side push cylinder 18 pushes the forging to the unpowered roller slide. The forging slides through the slide plate 31 into the roller conveyor section 32, waiting to be picked up. If the temperature does not meet the standard, the control system can adjust the roller speed or fan speed to extend the cooling time until it meets the requirements.
