Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts manufacturing, and in particular to cooling equipment for intelligent manufacturing of automobile parts. Background Art

[0002] In the manufacturing process of automotive parts, die-casting technology is usually used to mass-produce automotive parts such as gearbox housings. The temperature of die-casting parts is between 250℃ and 350℃ when they are just out of the mold. The natural cooling rate of die-casting parts is slow, so factories usually use air cooling or water cooling to force-cool the die-casting parts to increase the cooling rate. Among them, water cooling has high cooling efficiency and can effectively reduce the temperature of the casting or cavity surface. It can be used for castings and molds with large heat dissipation.

[0003] At present, there are two main methods for water cooling of automotive castings. One is to directly put the castings into cold water or spray cooling water on the casting surface. The other is to set a cooling water pipe on the casting mold to allow circulating water to flow into the molding insert or core to carry the heat out of the mold. The former will cause intense cooling of the casting and increase the defects of the casting, while the latter will increase the manufacturing cost of the mold and make the cooling effect uneven. Both water cooling methods will have a significant impact on the molding quality of the casting. Therefore, a cooling device for intelligent manufacturing of automotive parts is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that currently there are two methods for water cooling of automobile castings. One is to directly put the casting into cold water or spray cooling water on the surface of the casting, and the other is to set a cooling water pipe on the casting mold to allow circulating water to pass into the molding insert or core to carry heat out of the mold. The former will cause intense cooling of the casting and increase the defects of the casting, while the latter will increase the manufacturing cost of the mold and make the cooling effect uneven. Both water cooling methods will have a significant impact on the molding quality of the casting. The present invention provides a cooling device for intelligent manufacturing of automobile parts.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A cooling device for intelligent manufacturing of automotive parts, comprising a cooling box, wherein a support tray is provided inside the cooling box, a plurality of evenly distributed water flow holes are opened on the side wall of the support tray, lifting sleeves are fixedly installed on all four sides of the support tray, four lifting slides are fixedly installed on the bottom inner wall of the cooling box, the four lifting slides are slidably sleeved on the four lifting slides respectively, a frame is fixedly installed on one side of the cooling box, a winch is fixedly installed on the top of the frame, a traction rope is wound around the winch, a through hole is opened on one side of the top of the cooling box, one end of the traction rope passes through the through hole and is fixedly installed on one side of the support tray, and a gradient cooling component is provided on one side of the cooling box; The gradient cooling assembly is used to inject cooling water with successively lower temperatures into the cooling box to perform gradient cooling on the automotive parts; The gradient cooling assembly includes a plurality of gradient water tanks arranged on one side of the cooling box, and the plurality of gradient water tanks are fixedly stacked in sequence from top to bottom.

Two rack belts are provided inside the gear sealing box, and the rack belts located on the same side are tensioned on the plurality of transmission gears. A transmission motor is fixedly installed on the side wall of the gear sealing box, and the output shaft of the transmission motor is drivingly connected to one of the rotating shafts.

[0007] Furthermore, a slide groove is provided on the top of the cooling box, and a backflow cover is slidably installed inside the slide groove. Covering electric push rods are fixedly installed on both sides of the cooling box, and the telescopic ends of the covering electric push rods are fixedly installed with connecting frames, and one end of the two connecting frames is fixedly installed on the top of the backflow cover.

[0008] Furthermore, a mounting hole is provided on the top of the backflow cover, and a cooling fan is fixedly installed inside the mounting hole.

The cooling fan is located between the two air guide ducts, and the top ends of the two air guide ducts are both facing the side away from the cooling box.

[0010] Furthermore, a backflow net is fixedly installed inside the guide air duct.

[0011] Furthermore, the top of the guide air duct is provided with a guide inclined plate, and the guide inclined plates are rotatably mounted on the inner wall of the cooling box, and the two guide inclined plates are inclined toward the supporting tray, and the bottom of the guide inclined plates is provided with a support frame, and the support frame is fixedly mounted on the inner wall of the cooling box, and a buffer spring rod is fixedly mounted on the side of the support frame facing the guide inclined plate, and a universal ball is rotatably mounted on the telescopic end of the buffer spring rod facing the guide inclined plate, and the universal ball contacts the bottom side wall of the guide inclined plate, and limiting rods are fixedly mounted on the inner walls of both sides of the cooling box, and the two limiting rods are respectively located at the top of the guide inclined plate.

[0012] Furthermore, an agitator is fixedly mounted on the inner wall of the bottom of the cooling box, and a stirring motor is fixedly mounted on the bottom of the cooling box. The output shaft of the stirring motor extends into the interior of the cooling box and is drivingly connected to the agitator.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention provides a gradient cooling device, so that the components are cooled separately by cooling water with decreasing water temperature until the components are cooled to near room temperature. The components are cooled in a gradient stage rather than directly cooled to room temperature at one time, thus avoiding the drastic cooling of the components and significantly reducing the defects of the castings caused by cooling. At the same time, there is no need to set up cooling water channels inside the mold, which reduces the manufacturing cost of the mold. 2. The present invention provides multiple gradient water tanks. When the first component is cooled, the high-temperature component heats the cooling water, and the heated cooling water is recycled into the gradient water tank. Therefore, when subsequent components are cooled, the cooling water in the gradient water tank still maintains a sufficient temperature. Only fine-tuning the water temperature is required to meet the needs of the next round of cooling, without having to start heating from room temperature, saving heating time and energy. 3. The present invention provides a support tray to support components and automatically control the water inlet and outlet of components. When the water temperature inside the cooling box reaches a threshold, the support tray quickly carries the components out of the water. After the cooling water is replaced, the support tray quickly immerses the components in the water again, significantly shortening the time difference between the top and bottom of the components in contact with the cooling water, reducing the time when the temperature difference between the upper and lower parts occurs, and preventing defects. 4. The present invention provides mesh rollers so that after parts are placed in the tray, they fall onto multiple mesh rollers. The transmission motor drives the mesh rollers on both sides to rotate in opposite directions, so that both ends of the top parts are subjected to the reverse force generated by the mesh rollers, so that the parts are automatically brought to the middle position of the tray to prevent them from falling. At the same time, the parts are turned over on the mesh rollers so that all sides of the parts are evenly exposed to the cooling water. 5. The present invention provides a backflow cover so that after the parts enter the cooling box, the electric cover push rod drives the backflow cover to re-seal the top of the cooling box, thereby shielding the large amount of water vapor and water mist generated when the parts are cooled, so that they accumulate and condense at the bottom of the backflow cover and flow back into the cooling box, reducing the leakage of cooling water and preventing high-temperature water vapor from gushing directly from the top of the cooling box, thereby reducing the occurrence of safety accidents; 6. The present invention provides a cooling fan, which can generate wind to disperse the rising water vapor and accelerate the backflow of water vapor. At the same time, when the cooling water is replaced, the tray will carry the parts to the bottom of the cooling fan, and the cooling fan will cool the parts, shortening the cooling interval. When the parts are finally cooled to near room temperature, the cooling fan can dry most of the water stains on the surface of the parts, making it easier to recycle the parts. 7. The present invention provides a guide air duct so that the wind blown by the cooling fan will blow the water vapor to both sides. The high-temperature water vapor will surge upward along the guide air duct, thereby guiding and controlling the water vapor and preventing the disorderly surge and dispersion of water vapor. The water vapor blown into the guide air duct by the wind force of the cooling fan will contact the backflow net and then accumulate and condense on the backflow net, thereby generating backflow and recovering most of the water vapor. 8. The present invention provides guide ramps so that when dropped parts contact the guide ramps on both sides, they are guided and automatically fall into the receiving tray, achieving component positioning. When the parts contact the guide ramps, the impact force generated will squeeze the buffer spring rod through the guide ramps and the universal ball, and then cooperate with the limit rod to limit the top of the guide ramp, so that the reverse impact on the parts can be buffered, significantly reducing damage to the parts. 9. The present invention provides an agitator so that the stirring motor drives the agitator to rotate, thereby stirring the cooling water injected into the cooling box, so that the water temperature of the cooling water at various locations can be maintained within the same temperature range. When cooling the parts, the agitator stirs the cooling water, which can speed up the flow rate of the cooling water, make the parts contact the cooling water evenly, and at the same time improve the accuracy of the cooling thermometer in detecting the water temperature.

[0019] like Figures 1 to 9 As shown, a cooling device for intelligent manufacturing of automobile parts includes a cooling box 1, as shown in FIG. Figure 5 As shown, a tray 2 is provided inside the cooling box 1. Figure 7 As shown, a plurality of evenly distributed water flow holes 201 are opened on the side wall of the tray 2, and a lifting sleeve 3 is fixedly installed on all four sides of the tray 2. Four lifting slides 4 are fixedly installed on the bottom inner wall of the cooling box 1, and the four lifting sleeves 3 are slidably connected to the four lifting slides 4, as shown in FIG. Figure 3 As shown, a frame 5 is fixedly installed on one side of the cooling box 1, a winch 6 is fixedly installed on the top of the frame 5, a traction rope 7 is wound around the winch 6, a through hole 8 is opened on one side of the top of the cooling box 1, one end of the traction rope 7 passes through the through hole 8 and is fixedly installed on one side of the supporting tray 2, and a gradient cooling component is provided on one side of the cooling box 1. In this embodiment, the cooling device can be set at the bottom of the casting mold, or located at both ends of the conveying line with the mold, and transported to the top of the cooling box 1 for cooling by conveying equipment such as a conveyor and a robotic arm; The gradient cooling component is used to inject cooling water with successively lower temperatures into the cooling box 1 to perform gradient cooling on the automotive parts; like Figure 1 As shown, the gradient cooling assembly includes a plurality of gradient water tanks 9 arranged on one side of the cooling box 1. The plurality of gradient water tanks 9 are fixedly stacked in sequence from top to bottom, as shown in FIG. Figure 4 As shown, two circulation pipes 10 connected to the interior of the cooling box 1 are fixedly installed on one side of the cooling box 1, a circulation water pump 11 is fixedly installed on one end of the circulation pipe 10, and a multi-way pipe 12 is fixedly installed on the other end of the circulation water pump 11. Multiple ports of the two multi-way pipes 12 are respectively connected to the interior of multiple gradient water tanks 9, and control valves 13 are provided on multiple ports of the multi-way pipes 12. An insulating base 14 is fixedly installed at the bottom of the gradient water tank 9 at the bottom, and two external pipes 15 are fixedly installed on the other side of the gradient water tank 9. A heater 16 and a water tank thermometer 17 are fixedly installed on the side wall of the gradient water tank 9. Figure 5As shown, a cooling thermometer 18 is fixedly installed on one side of the cooling box 1. In this embodiment, the two circulation pipes 10 are respectively used to supply water to and drain water from the cooling box 1. Similarly, the two circulation water pumps 11 and the two multi-way pipes 12 are respectively used for the gradient water tank 9 to supply water for cooling to the cooling box 1, and the cooling box 1 to drain water from the gradient water tank 9 after cooling, so as to realize the circulation of cooling water between the gradient water tank 9 and the cooling box 1. The two external through pipes 15 on one side of each gradient water tank 9 are respectively used to replenish cold water to the gradient water tank 9 and to discharge excess cooling water from the gradient water tank 9. Liquid level gauges are provided inside the cooling box 1 and the gradient water tank 9 to monitor the amount of water inside the two to avoid excessive cooling water. The water temperature inside the gradient water tank 9 decreases from top to bottom. The temperature of the cooling water inside the gradient water tank 9 at the bottom is slightly higher than the room temperature to avoid condensation. The detection ends of the water tank thermometer 17 and the cooling thermometer 18 extend to the interior of the gradient water tank 9 and the cooling box 1 respectively, and are maintained at the bottom of the gradient water tank 9 and the cooling box 1.Specifically, the cooling equipment for intelligent manufacturing of automobile parts is provided with a gradient cooling device, so that when the first part in a round of processing is cooled, the cooling water inside the gradient water tank 9 is first heated by each heater 16, and the temperature of the cooling water in each gradient water tank 9 is controlled in combination with the water tank thermometer 17, so that the temperature of the cooling water decreases from top to bottom, and then the winch 6 reels the traction rope 7 to lift the support tray 2 upward along the lifting slide 4 to the highest point, and then the circulating water pump 11 draws the cooling water inside the top gradient water tank 9 and transports it to the cooling box 1 through the multi-way pipe 12 and the circulating pipe 10, so that the automobile parts After the mold is opened, the parts are directly placed inside the tray 2. The winch 6 controls the tray 2 to carry the parts and quickly descend and immerse them in the cooling water to start the first stage of cooling. The cooling thermometer 18 detects the water temperature. When the water temperature rises to the specified threshold, the circulating water pump 11 on the other side pumps the heated cooling water in the cooling box 1 back to the gradient water tank 9, and then injects the cooling water in the next gradient water tank 9 into the cooling box 1 to cool the parts for the second stage. This process is repeated until the parts are cooled to near room temperature, so that the parts receive gradient stage cooling instead of being cooled to room temperature directly at one time, thus avoiding the intense cooling of the parts and greatly reducing the production cost. The defects of castings caused by cooling are reduced. At the same time, there is no need to set up cooling water channels inside the mold, which reduces the manufacturing cost of the mold. By setting up the support tray 2, the support tray 2 can support the parts and realize automatic control of water inlet and outlet of the parts. When the cooling thermometer 18 detects that the water temperature inside the cooling box 1 reaches the threshold, the support tray 2 carrying the parts is quickly lifted to the bottom of the cooling box 1. After the circulating water pump 11 replaces the cooling water inside the cooling box 1, the support tray 2 carries the parts and quickly immerses them in water, which greatly shortens the time difference between the top and bottom of the parts contacting the cooling water, reduces the time when the temperature difference between the upper and lower parts occurs, and prevents uneven cooling. The problem of defects can be solved by providing multiple gradient water tanks 9, each with different water temperatures, to provide a stepped cooling function for components. When the first component is cooled, the high-temperature component heats the cooling water to cool itself. The heated cooling water is then recycled into the gradient water tank 9 to be used to cool the next component. Therefore, when other components are subsequently cooled, the cooling water in the gradient water tank 9 remains at a sufficient temperature. Simply by using the heater 16 and the external pipe 15 to inject cold water into the gradient water tank 9 and fine-tune the water temperature to meet the needs of the next round of cooling, there is no need to start heating from room temperature, saving heating time and energy.

[0020] like Figure 7As shown, a plurality of evenly distributed grid rollers 19 are rotatably installed inside the support tray 2, and a rotating shaft 20 is fixedly installed at one end of the grid rollers 19. A gear sealing box 25 is fixedly installed on one side of the support tray 2. One end of the plurality of rotating shafts 20 extends to the interior of the gear sealing box 25 and is fixedly sleeved with a transmission gear 22. A reverse gear 21 is fixedly sleeved on one end of the two rotating shafts 20 in the middle, and the two reverse gears 21 are meshed with each other. Two rack belts 23 are provided inside the gear sealing box 25, and the rack belts 23 on the same side are tensioned on a plurality of transmission gears 22. A transmission motor 24 is fixedly installed on the side wall of the gear sealing box 25, and the output shaft of the transmission motor 24 is drivingly connected to one of the rotating shafts 20. In this embodiment, all the grid rollers 19 are placed horizontally and parallel to each other. The number of grid rollers 19 and rotating shafts 20 is an even number. The rotating shafts 20 are connected to the support tray 2, the gear The inner wall of the wheel sealing box 25 is rotatably connected through a sealed bearing, and multiple rotating shafts 20 are distributed on both sides of the gear sealing box 25. The same rack belt 23 is tensioned on the rotating shaft 20 on each side. If the specifications and weight of the parts to be cooled are large during the actual production process, the combination of the transmission gear 22 and the rack belt 23 can be replaced by a sprocket and a chain; specifically, by providing a grid roller 19, after the parts are placed in the tray 2, they will fall on multiple grid rollers 19, and the transmission motor 24 drives the multiple grid rollers 19 on both sides to rotate in the opposite direction through the meshing transmission of the reverse gear 21, the transmission gear 22 and the rack belt 23, so that the two ends of the top parts are subjected to the reverse force generated by the grid roller 19, so that the parts are automatically brought to the middle position of the tray 2 to prevent them from falling, and at the same time, the parts are flipped on the grid roller 19 so that all sides of the parts are evenly exposed to the cooling water.

[0021] like Figure 3 As shown, a slide 101 is provided on the top of the cooling box 1, and a backflow cover 26 is slidably installed inside the slide 101, and a sealing electric push rod 27 is fixedly installed on both sides of the cooling box 1. The telescopic ends of the sealing electric push rod 27 are fixedly installed with a connecting frame 28, and one end of the two connecting frames 28 is fixedly installed on the top of the backflow cover 26; specifically, by arranging the backflow cover 26, before the parts are put in, the sealing electric push rod 27 drives the backflow cover 26 to slide on the top of the cooling box 1 through the connecting frame 28, so that the backflow cover 26 no longer covers the cooling box 1. After the parts enter the cooling box 1, the sealing electric push rod 27 drives the backflow cover 26 to be re-sealed on the top of the cooling box 1, thereby blocking a large amount of water vapor and water mist generated when the parts are cooled, so that they accumulate and condense at the bottom of the backflow cover 26 and flow back into the interior of the cooling box 1, reducing the leakage of cooling water and preventing high-temperature water vapor from directly gushing out from the top of the cooling box 1, thereby reducing the occurrence of safety accidents.

[0022] like Figure 8As shown, a mounting hole is provided at the top of the backflow cover 26, and a cooling fan 29 is fixedly installed inside the mounting hole; specifically, by arranging the cooling fan 29, when the parts are cooled, the cooling fan 29 can generate wind force to blow the surging water vapor into the inside of the cooling box 1, thereby accelerating the backflow of water vapor. At the same time, when the cooling water is replaced, the tray 2 will carry the parts out of the cooling water and lift them to the bottom of the cooling fan 29, so that during the replacement of the cooling water, the cooling fan 29 can be used to cool the parts, shortening the cooling interval. When the parts are finally cooled to near room temperature, the cooling fan 29 can blow away most of the water stains on the surface of the parts, thereby facilitating the recycling of the parts.

[0023] like Figure 5 As shown, air guide ducts 30 are fixedly installed on both sides of the cooling box 1, and the two air guide ducts 30 are symmetrically distributed with each other. The bottom ends of the two air guide ducts 30 extend to the interior of the cooling box 1, and the supporting tray 2 is located between the bottom ends of the two air guide ducts 30. The cooling fan 29 is located between the two air guide ducts 30, and the top ends of the two air guide ducts 30 are both facing the side away from the cooling box 1. In this embodiment, the top ends of the air guide ducts 30 can be closed or connected to the inside of other water storage equipment to guide and control the water vapor generated by cooling; specifically, by setting the air guide ducts 30, the wind blown by the cooling fan 29 will blow the water vapor to both sides, and the high-temperature water vapor will surge upward along the air guide ducts 30, thereby realizing the guidance and control of water vapor and avoiding disorderly surge and dispersion of water vapor.

[0024] like Figure 9 As shown, a backflow net 31 is fixedly installed inside the guide air duct 30; specifically, by setting the backflow net 31, the water vapor blown into the guide air duct 30 by the wind force of the cooling fan 29 will contact the backflow net 31, and then accumulate and condense on the backflow net 31, thereby generating backflow and recovering most of the water vapor.

[0025] like Figure 5 、 Figure 6As shown, the top of the guide air duct 30 is provided with a guide inclined plate 32, and the guide inclined plates 32 are rotatably mounted on the inner wall of the cooling box 1. The two guide inclined plates 32 are tilted toward the supporting tray 2. The bottom of the guide inclined plates 32 is provided with a support frame 33, and the support frame 33 is fixedly mounted on the inner wall of the cooling box 1. The support frame 33 is fixedly mounted with a buffer spring rod 34 on one side facing the guide inclined plate 32. The buffer spring rod 34 is rotatably mounted with a universal ball 35 on the telescopic end facing the guide inclined plate 32. The universal ball 35 contacts the bottom side wall of the guide inclined plate 32. Limit rods 36 are fixedly mounted on the inner walls of both sides of the cooling box 1. The two limit rods 36 are respectively located at the top of the guide inclined plate 32. In this embodiment, the guide ramp 32 is made of a high-temperature resistant soft material to reduce damage to the components when in contact with the components; specifically, by providing the guide ramp 32, if the components placed on the top of the cooling box 1 are misaligned with the support tray 2, they will contact the guide ramps 32 on both sides, and then automatically fall into the support tray 2 under the guidance of the inclined surface of the guide ramp 32, thereby achieving the positioning of the components. When the components contact the guide ramp 32, the impact force generated will squeeze the buffer spring rod 34 through the guide ramp 32 and the universal ball 35, and then cooperate with the limit rod 36 to limit the top of the guide ramp 32, so that the reverse impact on the components can be buffered, greatly reducing the damage to the components.

[0026] like Figure 5 As shown, an agitator 37 is fixedly installed on the bottom inner wall of the cooling box 1, and a stirring motor 38 is fixedly installed on the bottom of the cooling box 1. The output shaft of the stirring motor 38 extends to the interior of the cooling box 1 and is driven and connected to the agitator 37. In this embodiment, the output shaft of the stirring motor 38 is rotatably connected to the bottom side wall of the cooling box 1 through a sealed bearing. The agitator 37 corresponds to the position of the supporting tray 2 and is located at the bottom of the supporting tray 2 and between the four lifting slides 4; specifically, by arranging the agitator 37, the stirring motor 38 drives the agitator 37 to rotate, which can stir the cooling water injected into the cooling box 1, so that the water temperature of the cooling water at various locations can be maintained in the same temperature range. When cooling the components, the agitator 37 stirs the cooling water, which can speed up the flow rate of the cooling water, make the components contact the cooling water evenly, and at the same time improve the accuracy of the cooling thermometer 18 in detecting the water temperature.

[0027] In summary: Before cooling: When the first component in a round of processing is cooled, each heater 16 first heats the cooling water inside the gradient water tank 9, and the temperature of the cooling water in each gradient water tank 9 is controlled in combination with the water tank thermometer 17, so that the temperature of the cooling water decreases from top to bottom. The cover electric push rod 27 drives the backflow cover 26 to slide on the top of the cooling box 1 through the connecting frame 28, so that the backflow cover 26 no longer covers the cooling box 1, and then the winch 6 reels the traction rope 7, so that the support tray 2 is lifted up along the lifting slide 4 to the highest point. , then the circulating water pump 11 draws the cooling water from the top gradient water tank 9 and delivers it to the cooling box 1 through the multi-way pipe 12 and the circulating pipe 10. After the automobile parts are molded, the parts are directly placed inside the tray 2. The transmission motor 24 drives the multiple grid rollers 19 on both sides to rotate in the opposite direction through the meshing transmission of the reverse gear 21, the transmission gear 22, and the rack belt 23. The two ends of the top parts are subjected to the reverse force generated by the grid rollers 19, so that the parts are automatically brought to the middle position of the tray 2 to prevent them from falling. During cooling: the capping electric push rod 27 drives the backflow cover 26 to re-close the top of the cooling box 1, and the winch 6 controls the tray 2 carrying the parts to quickly descend and immerse them in the cooling water, starting the first stage of cooling. The parts are turned over on the grid drum 19 so that all sides of the parts are evenly exposed to the cooling water. The water temperature is detected by the cooling thermometer 18. When the water temperature rises to the specified threshold, the tray 2 carrying the parts is quickly lifted to the bottom of the cooling box 1, and the cooling fan 29 cools the parts. The circulating water pump 11 on the other side draws the heated cooling water in the cooling box 1 back to the gradient water tank 9, and then injects the cooling water in the next gradient water tank 9 into the cooling box 1. The tray 2 carries the parts and quickly immerses them in the water to cool the parts for the second stage, and so on until the parts are cooled to near room temperature, so that the parts receive gradient stage cooling instead of being cooled to room temperature directly at one time; After cooling: When the parts are finally cooled to near room temperature, the cooling fan 29 blows away most of the water stains on the surface of the parts, and then the cooled parts are taken out. The heater 16 cooperates with the external pipe 15 to inject cold water into the gradient water tank 9, and the water temperature is fine-tuned to meet the needs of the next round of cooling.
