Description

Technical Field

[0001] The utility model belongs to the technical field of die casting production, and in particular relates to an air-cooling conveying device for die castings. Background Art

[0002] Aluminum die-cast precision parts, composed of gearbox, outlet buckle sleeve, protective cover, motor cover, front housing. Gearbox is a device for transmitting power, usually made of aluminum die-casting. It can convert the speed and direction of rotational motion into the required output. It is commonly used in automobiles, industrial machinery and other fields. When the die-casting is just formed, it needs to be cooled as soon as possible due to the high temperature to avoid deformation and quality degradation. There are many ways to cool it, such as using a conveyor belt to transfer the die-casting to a wind cooling mechanism for cooling, or hanging the die-casting in front of a fan for air cooling after the die-casting is formed.

[0003] In the prior art, after searching, Chinese Patent No. CN116748487A discloses a metal die-casting cooling and conveying device; it includes a conveying frame, on which a water cooling trough for containing cooling water is provided; a chain plate conveying mechanism for cooling and conveying die-castings is installed in the water cooling trough on the conveying frame; the chain plate conveying mechanism includes two horizontal conveying chains and a plurality of conveying chain plates fixed between the two conveying chains, and the plurality of conveying chain plates are evenly distributed on the entire conveying chain.

[0004] During the conveying and cooling process of the die-castings, a conveyor belt is usually used to convey them to an air cooling mechanism for cooling. When the conveying time of the die-castings is slow, the conveying and cooling efficiency will be reduced. When the conveying process is fast, the cooling time is short, resulting in a poor cooling effect. In the above scheme, the conveying mechanism is cooled by an air cooling component and a water cooling component to convey and cool the die-castings. The conveying speed and cooling time of the die-castings by the chain conveying mechanism are difficult to control, which can easily lead to a short cooling process of the die-castings and a large amount of water resources wasted. In addition, direct contact between the conveying mechanism and water may cause operating failures, thereby reducing the efficiency of conveying and cooling the die-castings and increasing their cooling costs.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0014] Furthermore, a feed slot is provided at one end of the cooling box, and a plurality of windproof curtains are fixedly installed on the inner wall of the feed slot.

[0015] Furthermore, a side guard plate is fixedly installed on the top of the buffer plate, and a plurality of buffer pads are fixedly installed on the inner wall of the buffer plate.

[0031] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0033] See also Figure 1-Figure 5As shown, the utility model is a die-casting air-cooled conveying device, comprising a conveying bed 1, the inner wall of the conveying bed 1 is provided with a conveying roller 2, the top of the conveying bed 1 is slidably connected with a cooling box 3, the top of the cooling box 3 is provided with an air-cooling component 4, the top of the conveying bed 1 is symmetrically provided with a first fixed rod 5 and a second fixed rod 6, one side of the first fixed rod 5 and the second fixed rod 6 are fixedly connected with a transverse connecting rod 7, the outer surfaces of the first fixed rod 5 and the second fixed rod 6 are rotatably connected with a rotating sleeve 8, one side of the rotating sleeve 8 is fixedly connected with a top rotating rod 9, the outer surface of the top rotating rod 9 is fixedly connected with a connecting spring 10, the other end of the connecting spring 10 extends to the outer surface of the transverse connecting rod 7 and is fixedly connected thereto, and a buffer component 17 is provided at one end of the conveying bed 1.

[0034] When in use, the conveyor bed 1 is started to operate the conveyor rollers 2 on its inner wall, and the die-casting after processing is placed on the upper surface of the conveyor bed 1, so that it is gradually conveyed from the inlet end of the cooling box 3 to the inside through the operation of the conveyor rollers 2. At the same time, the air cooling assembly 4 on the top of the cooling box 3 is started to blow cold air from the top of the cooling box 3 to the upper surface of the conveyor bed 1. Since the operating speed of the conveyor rollers 2 is fixed, two sets of first fixing rods 5 and second fixing rods 6 are symmetrically arranged on both sides of the top of the conveyor bed 1. When the die-casting passes by, the air cooling assembly 4 on the top of the cooling box 3 is started. The jacking rods 9 on both sides are pushed forward by the jacking rods 9. At this time, the jacking rods 9 are driven by the extrusion force to drive the rotating sleeve 8 to rotate and displace on the outer surfaces of the first fixed rod 5 and the second fixed rod 6, thereby driving the connecting spring 10 to expand and retract in the direction of the die casting. At the same time, the die casting is slowed down by the reverse force of the jacking rods 9 and the connecting springs 10 until the die casting continues to move and pushes the jacking rods 9 to completely separate from the outer surface. Then, the die casting resumes its normal travel speed and moves to the end of the conveyor bed 1, where it is buffered and supported by the buffer assembly 17 for unloading.

[0035] The utility model supports the cooling box 3 above the conveying bed 1 so that a semi-enclosed cooling space is formed above the conveying bed 1. When the die-casting is transferred from the inlet end of the cooling box 3 to the middle section of the interior thereof through the conveying roller 2, the two sets of air-cooling components 4 are started at the same time to transfer the cold air downward, and the top rotating rod 9 is fixed to the opposite sides of the first fixing rod 5 and the second fixing rod 6 respectively, and the top rotating rod 9 is restricted by the elastically connected connecting spring 10. Since the die-casting has a certain weight, when the die-casting passes by, it pushes the top rotating rod 9 by itself to drive the rotating sleeve 8 to rotate and displace in the direction of the die-casting movement, and the die-casting is restricted by the elastic connection with the connecting spring 10 to generate a reverse force on the die-casting, which can slow down the travel speed of the die-casting when passing under the air-cooling component 4, increase the cooling time of the air-cooling component 4, and increase the cooling effect of the air-cooling. When it continues to move away from the bottom of the air-cooling component 4, it can resume the normal travel speed, thereby not affecting the subsequent output efficiency of the die-casting.

[0036] In one embodiment, for the first fan 401, the air cooling assembly 4 includes a first fan 401 and a second fan 402, and the first fan 401 and the second fan 402 are both provided with fan blades 403;

[0037] The outer surfaces of the first fan 401 and the second fan 402 are both provided with guide grooves 404 , the top of the cooling box 3 is provided with a through groove 11 , and the bottoms of the first fan 401 and the second fan 402 are both connected to the through groove 11 .

[0038] The first fan 401 and the second fan 402 are arranged side by side at the top of the cooling box 3 near the inlet end. When the conveying roller 2 starts to rotate, the first fan 401 and the second fan 402 are started to simultaneously drive the fan blades 403 to operate and suck the external air to flow, which flows through the guide groove 404 to the inside of the through groove 11 and continuously conveys the cold air downward.

[0039] By arranging the first fan 401 and the second fan 402 at the top of the cooling box 3 at intervals, the cold air transmission range is increased, thereby improving the cooling range of the die-casting during transportation. The continuously rotating fan blades 403 cooperate with the through grooves 11 to continuously deliver cold air to the interior of the cooling box 3 to dissipate heat and cool the die-casting, thereby achieving a better cooling effect during the transportation process.

[0040] In one embodiment, for the above-mentioned U-shaped condenser 12, the top of the first fan 401 is fixedly connected with the U-shaped condenser 12, one end of the U-shaped condenser 12 extends to the top of the second fan 402, and the outer surface of the U-shaped condenser 12 is fixedly connected with the delivery pipe 13.

[0041] The other end of the delivery pipe 13 is connected to the condensing device. When the first fan 401 and the second fan 402 are started at the same time, the fan blades 403 inside them continue to rotate, and the cooled water mist enters the delivery pipe 13 and flows into the interior of the U-shaped condenser 12. The two sets of fan blades 403 continuously rotate to generate suction, which draws the cooling water mist inside into the cooling box 3 and flows downward, thereby increasing the cooling degree of the airflow in contact with the die-casting.

[0042] By connecting the two ends of the bottom of the U-shaped condenser 12 to the top of the first fan 401 and the second fan 402 respectively, low-temperature water mist can be transported to the inside of the first fan 401 and the second fan 402 at the same time. By continuously rotating with the fan blades 403, it is continuously pumped downward to contact the die-casting to cool it, thereby increasing the cooling effect on the die-casting.

[0043] In one embodiment, for the above-mentioned connecting port 14 , connecting ports 14 are opened on both sides of the cooling box 3 , and suction fans 15 are fixedly installed on both sides of the cooling box 3 , and the suction end side of the suction fan 15 is connected to the connecting port 14 .

[0044] By arranging suction fans 15 on both sides of the cooling box 3, since the die-casting dissipates heat and generates hot air flow while cooling, when the die-casting enters the cooling box 3 for air cooling, the suction fan 15 is started to generate a reverse suction force to suck the hot air flow emitted from the cooling box 3 to the outside of the cooling box 3.

[0045] By setting the suction fan 15, when the batch die-castings are cooled by cold air, the heat dissipation generates a large amount of hot air flow, and the suction fan 15 generates a reverse suction force and performs suction simultaneously, so that the hot air flow inside the cooling box 3 can be quickly drawn to the outside of the connecting port 14, thereby preventing the slow dissipation rate of the hot air flow from affecting the cooling effect of subsequent die-castings.

[0046] In addition, in specific applications, the suction fan 15 is close to the outlet end of the cooling box 3, and its operating speed is lower than that of the first fan 401 and the second fan 402, so as to prevent it from absorbing too fast and affecting the air cooling effect.

[0047] In one embodiment, for the above-mentioned buffer plate 1701, the buffer assembly 17 includes a buffer plate 1701, and both side surfaces of the buffer plate 1701 are fixedly installed with a rotating plate 1702, one end of the rotating plate 1702 is rotatably connected to the outer surface of the conveying bed 1, and a buffer spring 1703 is symmetrically arranged at the bottom of the buffer plate 1701, and the other end of the buffer spring 1703 is fixedly installed on the outer surface of the conveying bed 1.

[0048] The buffer plate 1701 is supported in a downwardly inclined manner at the end exit of the conveyor bed 1 by the rotating plate 1702 and the buffer spring 1703. When the die-casting is continuously conveyed to the exit through the conveyor roller 2, it falls into the upper surface of the buffer plate 1701 by itself. The buffer plate 1701 is pressed by its own gravity when the die-casting falls, driving the rotating plate 1702 to rotate downward. The buffer plate 1701 is moved downward by the elastic expansion and contraction action of the buffer spring 1703 until the die-casting slides off the surface of the buffer plate 1701, and the buffer spring 1703 is reset to drive the buffer plate 1701 to return to its original position.

[0049] The buffer plate 1701 is elastically supported at the outlet end of the conveyor bed 1 by the buffer spring 1703. Through cooperation with the rotating plate 1702, when the die-casting is output to the outlet, it falls to the upper surface of the buffer plate 1701 by itself, and then the buffer plate 1701 is pressed by its own gravity, driving the buffer spring 1703 to be elastically compressed and driving the rotating plate 1702 at the other end to flip so that the end of the buffer plate 1701 continues to tilt downward, providing elastic support and buffering effect for the die-casting when it is discharged, thereby preventing the die-casting from being damaged by sudden falling during discharge.

[0050] In one embodiment, for the above-mentioned feed slot 16 , a feed slot 16 is opened at one end of the cooling box 3 , and a plurality of windproof curtains 18 are fixedly installed on the inner wall of the feed slot 16 .

[0051] A plurality of windproof curtains 18 are fixed on the outside of the feed slot 16. The die-casting pushes the windproof curtains 18 to swing by itself when passing through the feed port end of the cooling box 3. When the die-casting continues to move forward and moves away, the windproof curtains 18 return to their original positions to semi-close the feed slot 16, thereby preventing the internal cold air from dissipating too quickly to the outside of the cooling box 3 and affecting the cooling effect on the die-casting.

[0052] In one embodiment, for the above-mentioned side guard plate 1704, the side guard plate 1704 is fixedly installed on the top of the buffer plate 1701, and a plurality of buffer pads 1705 are fixedly installed on the inner wall of the buffer plate 1701, and the plurality of buffer pads 1705 are all arc-shaped and evenly arranged at the bottom of the inner wall of the buffer plate 1701.

[0053] The side guard plates 1704 are located on both sides of the buffer plate 1701 and extend to the top. When the die-casting falls to the upper surface of the buffer plate 1701, the side guard plates 1704 block it on both sides to prevent the die-casting from falling outward. The buffer pads 1705 play a buffering and protective role to prevent the die-casting from being damaged by collision when falling.

[0054] In one embodiment, for the above-mentioned top slide groove 19 , a top slide groove 19 is opened on the top of the conveying bed 1 , and the top slide groove 19 is symmetrically arranged on the top of the conveying bed 1 , and the bottom of the cooling box 3 is slidably connected to the inner wall of the top slide groove 19 .

[0055] The top slide 19 is located on both sides of the top of the conveyor bed, and the two sides of the bottom of the cooling box 3 are respectively slidably connected to the corresponding top slide 19. By pushing the cooling box 3, the bottom of the top slide 19 can drive the inner wall to slide and move, thereby changing its supporting position above the conveyor bed 1, making it convenient for the operator to observe the progress of the die-casting.

[0056] In one embodiment, for the above-mentioned columns 20 , the top of the conveyor bed 1 is symmetrically provided with columns 20 , and L-shaped baffles 21 are inserted into the interior of the columns 20 .

[0057] The column 20 is fixed to the top of the conveyor bed 1 near the inlet end, and two groups of L-shaped baffles 21 are extended from the inner side of the column 20. When the die-casting needs to be conveyed, a limiting channel is formed by the two groups of L-shaped baffles 21 to limit the conveying path of the die-casting, so that it can move forward at the center above the conveyor roller 2, so that it can easily pass through the central gap of the top rotating rod 9 and be cooled directly below the cold wind.

[0058] In one embodiment, for the above-mentioned limiting holes 22 , a plurality of limiting holes 22 are opened on the outer surface of the L-shaped baffle 21 , and a fixing bolt 23 is threadedly connected to the outer surface of the column 20 .

[0059] The limiting hole 22 is located on the lateral outer surface of the L-shaped baffle 21, and the fixing bolt 23 passes through the column 20 and extends to the inside of the limiting hole 22 on the outside of the L-shaped baffle 21 and is threadedly connected thereto. By loosening the fixing bolt 23 to disengage it from the corresponding limiting hole 22, the L-shaped baffle 21 can be pushed to move left and right on the outside of the column 20 until it moves to an appropriate position and the fixing bolt 23 is rotated again to pass through the limiting hole 22 to thread-lock it. In this way, the passing gap between the two groups of L-shaped baffles 21 can be adjusted according to the lateral width of the die-casting, so as to provide corresponding limiting channels for die-castings of different specifications.

[0060] In summary, with the aid of the above technical solution of the utility model, by fixing two groups of columns 20 at the top of the conveyor bed 1 near the inlet end, two groups of L-shaped baffles 21 extend oppositely from the inner side of the columns 20, when it is necessary to convey the die-casting, the conveyor bed 1 is started to operate the conveying rollers 2 on its inner wall, and the two groups of L-shaped baffles 21 form a limiting channel, which limits the conveying path of the die-casting at the inlet end, so that it moves forward at the center above the conveying roller 2, and at the same time starts the first fan 401 and the second fan 40 2 drives the internal fan blades 403 to operate to generate suction to continuously pump external air into the interior of the cooling box 3, and cooperates with the U-shaped condenser 12 to continuously transport cooling water mist and cold air to the bottom to contact the passing die-casting. During the movement of the die-casting, the top rotating rod 9 is pushed to cause the rotating sleeve 8 at the other end to flip, and the elastic stretching of the connecting spring 10 cooperates to limit the travel speed of the die-casting, so that it slowly passes through the area below the cold wind blowing, thereby increasing its cooling time and range, and through the limiting channel formed by the L-shaped baffle 21 at the inlet end, it passes through the central gap of the top rotating rod 9 and is cooled directly below the cold wind blowing. At the same time, the suction fan 15 synchronously operates to suck the hot air flow emitted from the cooling box 3, thereby increasing the dissipation efficiency of the hot air flow at the connecting port 14. After the die-casting is separated from the top rotating rod 9, it automatically resumes its normal travel speed, thereby improving the cooling effect of the die-casting without reducing its subsequent transportation efficiency, and saving its cooling processing cost. In addition, by arranging a windproof curtain 18 on the outside of the feed slot 16, it can prevent The cooling wind is dissipated outward and affects the cooling effect. After the die-casting is output to the end of the conveyor bed 1, it falls automatically to the top of the buffer plate 1701. Its own gravity presses the buffer plate 1701, driving the rotating plate 1702 to flip and compress the buffer spring 1703 below, providing an elastic buffering and material feeding protection effect for the die-casting. When the die-casting passes through the upper surface of the buffer plate 1701, the side guard plates 1704 on both sides can prevent it from falling outward, and the buffer pads 1705 at the bottom prevent it from colliding and causing external damage.

[0061] Through the above technical scheme, 1. By supporting the cooling box 3 above the conveying bed 1, a semi-enclosed cooling space is formed above the conveying bed 1. When the die-casting is transferred from the inlet end of the cooling box 3 to the middle section thereof through the conveying roller 2, the two sets of air cooling components 4 are simultaneously started to transfer the cold air downward, and the top rotating rod 9 is respectively fixed on the opposite sides of the first fixed rod 5 and the second fixed rod 6, and the top rotating rod 9 is restricted by the elastically connected connecting spring 10. Since the die-casting has a certain weight, when the die-casting passes by, it pushes the top rotating rod 9 by itself to drive the rotating sleeve 8 to rotate and displace following the direction of the die-casting, and through the elastic connection with the connecting spring 10 The action of the suction fan 15 can generate a reverse force on the die-casting to restrict the die-casting, which can slow down the speed of the die-casting when passing under the air-cooling component 4, increase the cooling time of the air-cooling component 4, and increase the cooling effect of the air-cooling. When it continues to move away from the bottom of the air-cooling component 4, it can resume its normal speed, thereby not affecting the subsequent output efficiency of the die-casting; 2. Through the setting of the suction fan 15, when the batch of die-castings are cooled by cold air, the heat dissipation generates a large amount of hot air flow, and the suction fan 15 generates a reverse suction force for simultaneous suction, so that the hot air flow inside the cooling box 3 can be quickly drawn out of the connecting port 14 to prevent the slow dissipation rate of the hot air flow from affecting the cooling effect of subsequent die-castings.
