Description

Technical Field

[0001] The invention relates to a heat-resistant and corrosion-resistant magnesium alloy preparation device, in particular to a heat-resistant and corrosion-resistant magnesium alloy preparation process for automobile engine cylinders, and belongs to the technical field of magnesium alloy preparation devices. Background Art

[0002] Compared with traditional magnesium alloys, heat-resistant and corrosion-resistant magnesium alloys have significantly higher heat resistance temperatures and can be used for a long time in a certain high-temperature environment without obvious performance degradation. They have strong resistance to various corrosive media, effectively reducing material damage and failure caused by corrosion. They are widely used in the manufacture of high-temperature components such as engine cylinders and transmission housings to improve automobile performance and fuel economy. In the hot-melt preparation process of heat-resistant and corrosion-resistant magnesium alloys, the raw materials need to be preheated in a heating box.

[0003] In the prior art, for example, the invention with application number 202221041700.1 discloses an insulation box for metal heating. In order to solve the problem that metals are piled together and cannot be fully heated, a rotating mechanism is set up, and a motor drives a screw rod to rotate through a belt. The movable sleeve is in the shape of a rectangular parallelepiped. The rotation of the screw rod drives the movable sleeve to rotate, and the connecting column moves in a spiral ascending sliding hole, so that the movable sleeve moves up and down while rotating, which not only accelerates the air circulation in the heating chamber, but also facilitates the comprehensive heating of the metal.

[0004] Similar to the above application, there are still some shortcomings:

[0005] The metal material is installed in a suspended manner, which makes loading and taking out inconvenient. The entire door panel needs to be completely opened to take out the metal material. The magnesium alloy is not put in at the same time during smelting, and some materials added in the middle still need to be stored inside the box, which will cause heat loss inside the box and increase energy consumption.

[0006] Therefore, a preparation process of heat-resistant and corrosion-resistant magnesium alloy for automobile engine cylinder block is designed to optimize the above problems. Summary of the invention

[0007] The main purpose of the present invention is to provide a preparation process of heat-resistant and corrosion-resistant magnesium alloy for automobile engine cylinder body.

The discharge mechanism composed of a cylindrical barrel, a conveying through pipe, a shaft rod, a paddle plate, and a conveying motor, in conjunction with a rotating motor and a first gear, The angle adjustment mechanism composed of the gear blocks can adjust the angle of the discharge mechanism during use to facilitate loading and unloading. In addition, during the loading and unloading process, the inside of the cylindrical barrel can be blocked by the paddle plate to reduce the discharge of hot air during the discharge process, which is more energy-efficient. The conveying mechanism consists of a mounting frame, a second gear, a third gear, a double-sided toothed belt, and a fourth gear. The third gear is installed on the output end of the conveying motor, and the fourth gear is connected to the roller of the conveyor belt.

DETAILED DESCRIPTION

[0032] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0033] like Figure 1-Figure 8 As shown, the present embodiment provides a preparation process of a heat-resistant and corrosion-resistant magnesium alloy for an automobile engine cylinder block, comprising a preheating box 1, a door panel 4 located at the front end of the preheating box 1, and a flipping mechanism 5 for controlling the door panel 4 to flip and open up and down, a movable bracket 2 is provided inside the preheating box 1, a conveyor belt 3 is horizontally provided on the bracket 2, two groups of conveyor belts 3 are provided and are arranged in parallel up and down, a through opening 6 is provided at the middle position of the door panel 4, a partition 7 is vertically slidably provided inside the through opening 6, a slide groove 8 is provided at the top and bottom of the through opening 6, a discharging mechanism 9 for loading and unloading metal materials is provided at the middle position of the partition 7, a lifting mechanism 10 for controlling the partition 7 to slide up and down is provided on the top of the door panel 4, and a conveying mechanism 11 for controlling the rotation of the conveyor belt 3 is provided inside the preheating box 1.

[0034] Overall working principle: When preheating the metal material, the door panel 4 can be directly opened, the bracket 2 can be taken out, the metal material can be placed on the top of the bracket 2 outside, and then the bracket 2 can be pushed into the preheating box 1 to complete the loading of the metal material. In addition, after the preheating of the metal material is completed, the bracket 2 can be directly pulled out to remove the metal parts. Although this method is fast, it will cause heat loss during the discharge process. In order to reduce the heat loss, a slow discharge method can also be used to take out and load the metal material. When loading, the lifting mechanism 10 is used to control the sliding of the partition 7, and the discharge mechanism 9 is located on the top of the conveyor belt 3, and then the discharge mechanism 9 is controlled to be located at the preheating One end of the interior of the box 1 is tilted downward toward the conveyor belt 3, and then the metal material is injected into the interior of the discharge mechanism 9 from the outside. The metal material falls onto the top of the conveyor belt 3 through the discharge mechanism 9. At the same time, the conveying mechanism 11 is used to control the stable movement of the conveyor belt 3 to ensure that the metal material is evenly spread on the top of the conveyor belt 3. When discharging the metal material, the partition 7 is moved downward, the discharge mechanism 9 is located below the conveyor belt 3, and then the discharge mechanism 9 is tilted upward toward the conveyor belt 3. By starting the conveying mechanism 11, the metal material falls into the interior of the discharge mechanism 9, and then the discharge mechanism 9 is used to discharge the metal material downward. This method does not require the door panel 4 to be opened as a whole, thereby reducing heat loss.

[0035] In this embodiment, the bracket 2 includes a rectangular frame, a carrier plate and a movable wheel. The rectangular frame is symmetrically provided with two groups, and a carrier plate is horizontally fixed between the two groups of rectangular frames. The carrier plates are provided in two groups and are parallel to each other. The conveyor belt 3 is located on the top of each carrier plate, and the bottom of the rectangular frame is equipped with a movable wheel.

[0036] Partial working principle: The bracket 2 is provided with a double-layer carrier plate, and the conveyor belts 3 are respectively located on the two sets of carrier plates, which can carry out double-layer loading of metal raw materials, and the setting of the bottom moving wheels can facilitate the movement of the bracket 2, making it more convenient to use.

[0037] In this embodiment, the flipping mechanism 5 includes a fixed seat 16, a positioning block 17, a fixed rod 18, a worm gear 19, a flipping motor 20 and a worm 21. The fixed seat 16 is fixed to the top of the preheating box 1, and the door panel 4 is fixed with positioning blocks 17 at both ends of the side close to the fixed seat 16. A fixed rod 18 is fixed between the two groups of positioning blocks 17. A worm gear 19 is fixed at the middle position of the fixed rod 18. The fixed rod 18 passes through the fixed seat 16 and is rotatably connected to the fixed seat 16. A flipping motor 20 is installed inside the fixed seat 16, and a worm 21 meshing with the worm gear 19 is installed at the output end of the flipping motor 20.

[0038] Partial working principle: When the door panel 4 is opened as a whole, the flip motor 20 is started to drive the worm 21 to rotate. The rotation of the worm 21 can control the rotation of the worm wheel 19. The worm wheel 19 drives the fixing rod 18 and the door panel 4 to flip up to open the door panel 4. The door panel 4 is flipped down to close the door panel 4.

[0039] In this embodiment, a receiving groove 12 is provided at one end of the bottom of the preheating box 1 close to the door panel 4, a guide block 13 is slidably installed inside the receiving groove 12, a spring 14 is fixed between the guide block 13 and the end of the receiving groove 12, and a pull rope 15 is provided on the top of the guide block 13, the pull rope 15 slides out from the inside of the preheating box 1 and is fixedly connected to the side of the door panel 4.

[0040] Partial working principle: When the door panel 4 is flipped upward and opened, a pulling force is applied to the pull rope 15, and the guide block 13 can be pulled outward by the pull rope 15, and the spring 14 can be stretched. The guide block 13 is located at the bottom end of the preheating box 1 to facilitate the movement and pulling out of the bracket 2. When the door panel 4 is closed, the pull rope 15 loses its pulling force, and the guide block 13 slides back to the inside of the storage groove 12 under the elastic force of the spring 14.

[0041] In this embodiment, the lifting mechanism 10 includes a lifting motor 22, a screw 23 and a threaded groove 24. The lifting motor 22 is installed at the middle position of the top of the door panel 4. The output end of the lifting motor 22 is installed with a screw 23. The screw 23 extends to the inside of the slide groove 8. The top of the partition 7 is provided with a threaded groove 24 that cooperates with the screw 23.

[0042] Partial working principle: When loading and unloading metal materials, start the lifting motor 22 to drive the screw 23 to rotate. The rotation of the screw 23 will control the door panel 4 to slide inside the slide groove 8, thereby controlling the lifting and lowering of the door panel 4 and adjusting the position of the discharge mechanism 9.

[0043] In this embodiment, the discharge mechanism 9 includes a cylindrical barrel 25, a conveying pipe 26, a shaft 27, a paddle 28, a conveying motor 29 and an angle adjustment mechanism. The cylindrical barrel 25 is rotatably mounted on the partition 7. The cylindrical barrel 25 is parallel to the length direction of the partition 7. The top of the partition 7 is provided with an angle adjustment mechanism for controlling the rotation of the cylindrical barrel 25. Conveying pipes 26 are provided on both sides of the cylindrical barrel 25. A conveying motor 29 is installed at a position on the partition 7 at the end of the cylindrical barrel 25. A shaft 27 is installed at the output end of the conveying motor 29. The shaft 27 is rotatably mounted between the two ends of the cylindrical barrel 25, and a paddle 28 is evenly fixed on the outside of the shaft 27.

[0044] Partial working principle: When loading is performed through the discharge mechanism 9, the delivery pipe 26 outside the cylindrical barrel 25 is tilted upward, and the delivery pipe 26 inside the preheating box 1 is located above the conveyor belt 3. After the metal material is poured into the delivery pipe 26 outside the preheating box 1, the conveying motor 29 is started to drive the shaft 27 and the paddle 28 to rotate. The paddle 28 pushes the metal material into the preheating box 1 and drops it above the conveyor belt 3. At the same time, the conveying mechanism 11 is used to control the conveyor belt 3 to move toward the inner end of the preheating box 1, so that the metal material falls evenly on the conveyor belt 3. After the loading is completed, the paddle 28 presses the cylindrical barrel 25 to move the metal material evenly. The inner shielding of 25 ensures the sealing of the preheating box 1. When the material is taken out after the preheating is completed, the downward movement of the partition 7 is controlled. At this time, the conveying pipe 26 inside the preheating box 1 is located below the conveyor belt 3. The conveying mechanism 11 controls the conveyor belt 3 to move toward the door panel 4, and the metal material will fall into the conveying pipe 26 inside the preheating box 1. Then, the conveying motor 29 is started to drive the shaft 27 and the paddle 28 to rotate. The paddle 28 pushes the metal material out of the interior of the preheating box 1 and tilts it down. In the process of discharging, due to the existence of multiple groups of paddles 28, the preheating box 1 will not be directly connected to the outside world, thereby effectively reducing heat loss.

[0045] In this embodiment, four groups of the paddle plates 28 are provided, and the angle between adjacent paddle plates 28 is 90°. The height of the delivery through pipe 26 is smaller than the distance between the outer ends of the two groups of paddle plates 28 .

[0046] Partial working principle: During the rotation of the paddle 28, there must be two sets of paddles 28 arranged opposite to each other inside the cylindrical tube 25, which isolate the preheating box 1 from the outside.

[0047] In this embodiment, the end of the conveying through pipe 26 inside the preheating box 1 is provided with an inclined port, and the end of the conveying through pipe 26 outside the preheating box 1 is provided with a trumpet-shaped opening.

[0048] Partial working principle: The setting of the inclined port on the conveying through pipe 26 can facilitate the reception of the fallen metal materials, while the setting of the trumpet-shaped opening can expand the area of ​​the port for storing and unloading materials.

[0049] In this embodiment, the angle adjustment mechanism includes a rotating motor 30, a first gear 31 and a gear block 32. The rotating motor 30 is installed inside the partition 7, and the rotating motor 30 is located above the cylindrical barrel 25. The first gear 31 is installed at the output end of the rotating motor 30, and the outer surface of the cylindrical barrel 25 is circumferentially provided with a gear block 32 that meshes with the first gear 31.

[0050] Local working principle: During the use of the discharging mechanism 9, it is necessary to control the angle of the cylindrical barrel 25, and place the conveying pipe 26 at an angle on the top or bottom of the conveyor belt 3. At this time, the rotating motor 30 is started to control the rotation of the first gear 31, and the first gear 31 is meshed with the gear block 32 to control the rotation of the cylindrical barrel 25, thereby changing the angle of the cylindrical barrel 25.

[0051] In this embodiment, the conveying mechanism 11 includes a mounting frame 33, a second gear 34, a third gear 35, a double-sided toothed belt 36 and a fourth gear 37. The mounting frame 33 is fixed to the inner side of the partition 7. The mounting frame 33 is provided with two groups. The second gear 34 is installed on the mounting frame 33. The third gear 35 is installed at the output end of the conveying motor 29. The double-sided toothed belt 36 is meshed and installed between the second gear 34 and the third gear 35. The fourth gear 37 is installed at the end of the roller on the conveyor belt 3. The spacing between the two groups of fourth gears 37 is greater than the vertical length of the double-sided toothed belt 36.

[0052] Partial working principle: In the initial state, the conveying passage 26 is located in the middle position of the two sets of conveyor belts 3, and the fourth gear 37 is not meshed with the double-sided toothed belt 36 at this time. When the lifting mechanism 10 controls the up and down movement of the partition 7, the fourth gear 37 is meshed with the double-sided toothed belt 36. In order to avoid the rotation of the conveyor belt 3 when the partition 7 moves vertically, the conveying motor 29 can be controlled to control the double-sided toothed belt 36 to rotate in the direction opposite to the moving direction of the partition 7. The conveyor belt 3 will remain stable when the partition 7 is raised and lowered, and then the conveying mechanism 11 on the partition 7 is moved to the specified position. When the conveyor belt 3 is loaded, the conveying is started. The motor 29 drives the third gear 35 to rotate clockwise, the third gear 35 drives the double-sided toothed belt 36 to rotate clockwise, and the double-sided toothed belt 36 drives the fourth gear 37 to rotate counterclockwise, thereby controlling the conveyor belt 3 to transport the metal material toward the inside of the preheating box 1. During the unloading process of the conveyor belt 3, the conveying motor 29 is started to drive the third gear 35 to rotate counterclockwise, the third gear 35 drives the double-sided toothed belt 36 to rotate counterclockwise, and the double-sided toothed belt 36 drives the fourth gear 37 to rotate clockwise, thereby controlling the conveyor belt 3 to transport toward the door panel 4, and the metal material on the top of the conveyor belt 3 falls into the inside of the conveying pipe 26 for discharge.
