Description

Technical Field

[0001] This invention relates to the field of hot work die surface coating technology, specifically a high-performance hot work die surface coating pretreatment equipment. Background Technology

[0002] Hot work dies are a type of special mold used for hot forming of metals or alloys under extreme conditions such as high temperature, high pressure, high wear, and high alternating stress. They are core process equipment in modern manufacturing, especially in the automotive, aerospace, and energy equipment industries. To improve the quality of hot work dies, a high-temperature resistant, wear-resistant, and oxidation-resistant coating is applied to their surface. However, before applying the coating, the surface of the hot work die must be cleaned using ultrasonic cleaning equipment and then dried.

[0003] Chinese invention patent application CN109967678B discloses a forging die cleaning system, including a frame, a die conveying device, a hot air blower unit, an upper high-pressure cleaning device, a lower high-pressure cleaning device, a high-pressure spray cleaning chamber, and a lower filter device. It is equipped with a horizontal circulating trolley track, and the die is circulated and transported on a plane by the die conveying device for cleaning, thereby reducing the labor intensity of workers.

[0004] While the above solution can meet the cleaning and drying requirements of hot work molds, the molds are placed directly on the trolley during drying, while the drying equipment is located above the molds. During the drying process, the bottom of the molds and the contact area between the molds and the trolley cannot be fully dried, resulting in drying dead zones. Furthermore, since the drying device is directly fixed to the frame, the blowing range and angle of the hot air blower are limited. Even if the drying time is extended, it is difficult to guarantee the drying effect, and it also leads to low drying efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a high-performance pretreatment device for coating the surface of hot work dies, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-performance hot work die surface coating pretreatment device, comprising a worktable, a protective shell fixedly connected to the upper outer side of the worktable, an electric turntable fixedly installed at the upper end of the worktable, a rotating disk fixedly installed at the upper end of the electric turntable, and multiple support mechanisms installed in a ring array at the upper end of the rotating disk, each support mechanism consisting of two first support components and two second support components, the two second support components being symmetrically distributed between the two first support components, a die body being placed at the upper end of each support mechanism, the first support components and the second support components alternately supporting the die body, and two first semi-annular plates and two second semi-annular plates fixedly connected to the upper end of the worktable, the two ends of the first semi-annular plates and the second semi-annular plates being cut off to form inclined surfaces; The inner side of the protective shell is fixedly installed with multiple swing blower mechanisms and multiple first air knives in a ring array above the rotating disk.

[0009] Preferably, the second support assembly includes a second support frame disposed above the rotating disk, and second support seats are symmetrically fixedly installed on the upper end of the second support frame, and second card seats are fixedly installed on the sides of the second support seats that are far apart from each other. The lower end of the second support frame is symmetrically and fixedly connected with a second slide rod. The second slide rod passes downward through the rotating disk. A second ball is rolledly installed at the lower end of the second slide rod. A second limiting ring is fixedly sleeved on the outer side of the lower end of the second slide rod. A second return spring is sleeved on the outer side of the second slide rod. The two ends of the second return spring abut against the lower end of the rotating disk and the upper end of the second limiting ring, respectively.

[0010] Preferably, the second semi-annular plate is located on the rotation path of the second ball, and the second ball alternately rolls and contacts the second semi-annular plate and the rotating disk.

[0011] Preferably, the swing blower mechanism includes a semi-circular air guide pipe disposed above the mold body. Multiple air inlet pipes are fixedly connected at equal intervals on the outer side of the semi-circular air guide pipe, and multiple air outlet pipes are fixedly inserted at equal intervals on the inner side of the semi-circular air guide pipe. A second air knife is fixedly connected to the end of the air outlet pipe away from the semi-circular air guide pipe, and the second air knife is fixedly connected to the semi-circular air guide pipe through a bracket. The upper end of the semi-circular air duct is symmetrically equipped with a swing guide mechanism, and the upper end of the semi-circular air duct is equipped with a drive mechanism that drives the semi-circular air duct to swing back and forth.

[0012] Preferably, the swing guide mechanism includes a connecting frame symmetrically and fixedly connected to the top of the inner cavity of the protective shell, a slide block fixedly connected to the lower end of the connecting frame, a slide rail slidably installed at the lower end of the slide block, and a semi-annular air guide duct fixedly connected to the lower end of the slide rail.

[0013] Preferably, the driving mechanism includes a transmission plate fixedly connected to the side of the semi-annular air guide duct, a transmission groove is provided through the side of the transmission plate, a fixed plate is fixedly connected to the top of the inner cavity of the protective shell, and a circular plate is rotatably mounted on the side of the fixed plate near the transmission plate. The circular plate is driven by the motor shaft of a servo motor fixedly mounted on the side of the fixed plate. A circular shaft is fixedly connected to the side of the circular plate near the transmission plate, and a roller is rotatably mounted on the outer side of the circular shaft, with the roller inserted into the transmission groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. When the mold body needs to be dried, the dried mold body is removed through the loading and unloading port, and a new mold body to be dried is installed. At this time, the lower end of the mold body is in contact with the support mechanism, which supports and limits the mold body. The electric turntable drives the rotating disk to rotate intermittently, so that the mold body can be continuously installed and removed.

[0015] 2. When the rotating disc rotates, the mold body rotates synchronously through the support mechanism. At this time, the mold body passes through the bottom of the swing blower mechanism and the side of the first air knife. The bottom of the mold body is dried by blowing air through the first air knife. The drive mechanism drives the semi-circular air guide pipe to swing back and forth. The semi-circular air guide pipe drives multiple second air knives to swing back and forth, so that the hot air blown by the second air knife covers the surface of the mold body. At the same time, the hot air blown by the second air knife has a sweeping effect. Meanwhile, the airflow direction of the hot air swings left and right and constantly changes, producing a stirring and peeling effect, which is more conducive to blowing out and blowing away the water in the depressions on the surface of the mold body, thereby improving the drying effect of the mold body.

[0016] 3. When the rotating disc drives the support mechanism to rotate to the intersection and overlap of the two first semi-annular plates and the two second semi-annular plates, the first support assembly and the second support assembly simultaneously support the mold body. When the support mechanism moves away from the top of the first semi-annular plate, the first support assembly releases its support for the mold body, while the second support assembly continues to support the mold body. This allows the first and second support assemblies to alternate stably, preventing the mold body from shaking or shifting. The first and second support assemblies support the mold body at different positions. During the movement of the mold body, multiple swing blower mechanisms and multiple first air knives work together to thoroughly dry the mold body, greatly improving the drying efficiency and effect.

[0019] 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, and 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.

[0020] Please see Figures 1 to 12This invention provides a technical solution: a high-performance pretreatment device for the surface coating of hot work dies, comprising a workbench 1, a protective shell 11 fixedly connected to the outer side of the upper end of the workbench 1, an electric turntable 12 fixedly installed on the upper end of the workbench 1, a rotating disk 13 fixedly installed on the upper end of the electric turntable 12, and multiple support mechanisms arranged in a circular array on the upper end of the rotating disk 13. Each support mechanism consists of two first support components and two second support components, with the two second support components symmetrically distributed between the two first support components. A die body 4 is placed on the upper end of each support mechanism. The support components alternately support the mold body 4, and the first support component and the second support component support the bottom of the mold body 4 at different positions. By alternating support from the first support component and the second support component, the bottom of the mold body 4 can be thoroughly dried, avoiding incomplete drying of the bottom of the mold body 4. The upper end of the worktable 1 is fixedly connected to two first semi-annular plates 5 and two second semi-annular plates 51. Both ends of the first semi-annular plates 5 and the second semi-annular plates 51 are cut off to form inclined surfaces. The diameters of the first semi-annular plates 5 and the second semi-annular plates 51 are different, and the two ends of the two second semi-annular plates 51 extend to the space between the two first semi-annular plates 5. Multiple oscillating blower mechanisms and multiple first air knives 61 are fixedly installed in a ring array on the inner side of the protective shell 11 above the rotating disk 13. The multiple oscillating blower mechanisms and multiple first air knives 61 are alternately distributed. The oscillating blower mechanisms span the outer side of the mold body 4. The first air knives 61 are fixedly connected to the top of the inner cavity of the protective shell 11 through the bracket. The worktable 1 and the side of the protective shell 11 are provided with loading and unloading stations, and the side of the protective shell 11 is provided with loading and unloading ports. The mold body 4 can be easily installed and disassembled through the loading and unloading ports.

[0021] Both the first air knife 61 and the oscillating blower mechanism are connected to the branch pipe, which is connected to the air duct. The air duct is connected to the air outlet of the hot air blower, which can blow out high-pressure hot air.

[0022] An air extraction port is installed at the lower end of the workbench 1. Air can be extracted through the air extraction port by an air extraction mechanism or a negative pressure mechanism to collect the water vapor evaporated by heating, thereby improving the drying effect.

[0023] The electric turntable 12 intermittently drives the rotating disc 13 to rotate, and the rotating disc 13 drives the multiple support mechanisms on it to rotate. The support mechanisms drive the mold body 4 to rotate synchronously, so that the mold body 4 passes through the bottom of multiple swing blower mechanisms and the sides of multiple first air knives 61. The mold body 4 is dried by the cooperation of multiple swing blower mechanisms and multiple first air knives 61. During the rotation of the support mechanism, when the lower end of the first support component contacts the upper end of the first semi-annular plate 5, the first support component supports the mold body 4, while the second support component separates from the second semi-annular plate 51, and the upper end of the second support component moves away from the lower end of the mold body 4; when the second support component contacts the upper end of the second semi-annular plate 51, the second support component supports the mold body 4, while the first support component separates from the first semi-annular plate 51, and the upper end of the first support component moves away from the lower end of the mold body 4; by the alternating support of the first and second support components on the mold body 4, and with the cooperation of the swing blower mechanism and the first air knife 61, the mold body 4 can be dried effectively.

[0024] Please see Figures 2 to 4 , Figures 7 to 10 The first support component includes a first support frame 2 disposed above the rotating disk 13. A first support base 21 is symmetrically fixedly installed on the upper end of the first support frame 2. A first card seat 22 is fixedly installed on the side of the first support base 21 that is far apart from each other. Protective pads are provided at the contact positions of the first support base 21, the first card seat 22 and the mold body 4 to prevent scratches on the surface of the mold body 4. The lower end of the first support frame 2 is symmetrically and fixedly connected with a first slide rod 23. The first slide rod 23 passes downward through the rotating disk 13 and is slidably connected to the rotating disk 13. The lower end of the first slide rod 23 is rotatably mounted with a first ball bearing 24. The outer side of the lower end of the first slide rod 23 is fixedly sleeved with a first limiting ring 25. The outer side of the first slide rod 23 is sleeved with a first return spring 26. The two ends of the first return spring 26 abut against the lower end of the rotating disk 13 and the upper end of the first limiting ring 25, respectively. The first return spring 26 applies a downward elastic force to the first limiting ring 25.

[0025] The first semi-annular plate 5 is located on the rotation path of the first ball 24, and the first ball 24 alternately rolls and contacts the first semi-annular plate 5 and the rotating disk 13. That is, after the first ball 24 rolls a certain distance along the upper surface of the rotating disk 13, the first ball 24 rolls and contacts the first semi-annular plate 5. When the first ball 24 separates from the first semi-annular plate 5, the first ball 24 will roll along the upper surface of the rotating disk 13 again, and so on.

[0026] When the first support assembly supports the mold body 4, the first ball bearing 24 rolls along the inclined surface to the upper end of the first semi-annular plate 5. At this time, the first semi-annular plate 5 pushes the first ball bearing 24 to move upward. The first ball bearing 24 pushes the first slide rod 23 to slide upward along the rotating disk 13. The first slide rod 23 drives the first support frame 2 and the first limiting ring 25 to move upward. The first limiting ring 25 squeezes the first return spring 26. The first support frame 2 drives the first support seat 21 to contact the bottom of the mold body 4. The first support seat 21 drives the first locking seat 22 to lock onto the side of the mold body 4. The mold body 4 is supported by the first support seat 21 and the first locking seat 22.

[0027] When the first ball bearing 24 separates from the first semi-annular plate 5, the first limit ring 25 is pushed downward by the elastic force of the first reset spring 26. The first limit ring 25 drives the first support frame 2 to move downward through the first slide rod 23. The first support frame 2 drives the first support seat 21 and the first card seat 22 away from the mold body 4, so that the first support assembly is away from the mold body 4 and will not hinder the drying of the mold body 4.

[0028] Please see Figures 2 to 4 , Figures 7 to 9 The second support assembly includes a second support frame 3 disposed above the rotating disk 13. A second support base 31 is symmetrically fixedly installed on the upper end of the second support frame 3. A second card seat 32 is fixedly installed on the side of the second support base 31 that is far apart from each other. Protective pads are provided at the contact positions of the second support base 31, the second card seat 32 and the mold body 4 to prevent scratches on the surface of the mold body 4. The lower end of the second support frame 3 is symmetrically and fixedly connected with a second slide rod 33. The second slide rod 33 passes downward through the rotating disk 13 and is slidably connected to the rotating disk 13. A second ball bearing 34 is rolledly installed at the lower end of the second slide rod 33. A second limiting ring 35 is fixedly sleeved on the outer side of the lower end of the second slide rod 33. A second return spring 36 is sleeved on the outer side of the second slide rod 33. The two ends of the second return spring 36 abut against the lower end of the rotating disk 13 and the upper end of the second limiting ring 35, respectively. The second return spring 36 applies a downward elastic force to the second limiting ring 35.

[0029] When the weight of the mold body 4 is relatively heavy, the ball bearings can be replaced with pulleys to ensure that the support mechanism can rotate at the same time as the rotating disk 13.

[0030] The second semi-annular plate 51 is located on the rotation path of the second ball 34, and the second ball 34 alternately rolls and contacts the second semi-annular plate 51 and the rotating disk 13. That is, after the second ball 34 rolls a certain distance along the upper surface of the rotating disk 13, the second ball 34 rolls and contacts the second semi-annular plate 51. When the second ball 34 separates from the second semi-annular plate 51, the second ball 34 will roll along the upper surface of the rotating disk 13 again, and so on.

[0031] When the second support assembly supports the mold body 4, the second ball 34 rolls along the inclined surface to the upper end of the second semi-annular plate 51. At this time, the second semi-annular plate 51 pushes the second ball 34 to move upward. The second ball 34 pushes the second slide rod 33 to slide upward along the rotating disk 13. The second slide rod 33 drives the second support frame 3 and the second limiting ring 35 to move upward. The second limiting ring 35 squeezes the second return spring 36. The second support frame 3 drives the second support seat 31 to contact the bottom of the mold body 4. The second support seat 31 drives the second locking seat 32 to lock onto the side of the mold body 4. The mold body 4 is supported by the second support seat 31 and the second locking seat 32.

[0032] When the second ball 34 separates from the second semi-annular plate 51, the second limit ring 35 is pushed downward by the elastic force of the second reset spring 36. The second limit ring 35 drives the second support frame 3 downward through the second slide rod 33. The second support frame 3 drives the second support seat 31 and the second card seat 32 away from the mold body 4, so that the second support assembly is away from the mold body 4 and will not hinder the drying of the mold body 4.

[0033] When the support mechanism rotates to the intersection and overlap of the two first semi-annular plates 5 and the two second semi-annular plates 51, the first semi-annular plate 5 pushes the first support assembly to move upward to support the mold body 4, and the second semi-annular plate 51 pushes the second support assembly to move upward to support the mold body 4. That is, at this time, the first support assembly and the second support assembly support the mold body 4 simultaneously, so that the first support assembly and the second support assembly can alternate stably in the future, and avoid the mold body 4 from shaking or shifting.

[0034] Please see Figure 2 , Figure 6 and Figure 11The swing blower mechanism includes a semi-circular air guide duct 6 disposed above the mold body 4. Multiple air inlet pipes 62 are fixedly connected at equal intervals on the outer side of the semi-circular air guide duct 6, and multiple air outlet pipes 63 are fixedly inserted at equal intervals on the inner side of the semi-circular air guide duct 6. Both the air inlet pipes 62 and the air outlet pipes 63 are connected to the inner cavity of the semi-circular air guide duct 6. A second air knife 64 is fixedly connected to the end of the air outlet pipe 63 away from the semi-circular air guide duct 6. The air outlet pipe 63 is connected to the second air knife 64. The second air knife 64 is fixedly connected to the semi-circular air guide duct 6 through a bracket. A swing guide mechanism is symmetrically installed at the upper end of the semi-circular air guide duct 6, and a drive mechanism for driving the semi-circular air guide duct 6 to swing back and forth is installed at the upper end of the semi-circular air guide duct 6.

[0035] By cooperating with multiple air inlets 62, the air entering the inner cavity of the semi-annular air guide duct 6 can be evenly distributed, and the air blown out can be as even as possible. That is, the air from the inner cavity of the semi-annular air guide duct 6 can pass through the air outlet duct 63 and enter the second air knife 64 evenly, and the air blown out along the second air knife 64 can be evenly distributed, so as to dry the mold body 4 comprehensively and evenly.

[0036] Please see Figure 2 , Figure 6 and Figure 11 The swing guide mechanism includes a connecting frame 65 symmetrically fixedly connected to the top of the inner cavity of the protective shell 11. A slide block 66 is fixedly connected to the lower end of the connecting frame 65. A slide rail 67 is slidably installed at the lower end of the slide block 66. A groove adapted to the slide rail 67 is opened at the lower end of the slide block 66, so that the slide rail 67 can slide back and forth stably along the slide block 66. The lower end of the slide rail 67 is fixedly connected to the semi-annular air guide pipe 6. Through the cooperation between the slide rail 67 and the slide block 66, the semi-annular air guide pipe 6 can be suspended in mid-air.

[0037] The slide block 66, slide rail 67 and semi-circular air duct 6 have the same curvature. When the semi-circular air duct 6 swings back and forth, it drives the slide rail 67 to swing back and forth synchronously. The slide rail 67 swings back and forth along the slide block 66. The combination of the slide rail 67 and the slide block 66 enables the semi-circular air duct 6 to swing back and forth stably.

[0038] Please see Figure 11 and Figure 12 The drive mechanism includes a transmission plate 7 fixedly connected to the side of the semi-annular air duct 6. A transmission groove 71 is opened through the side of the transmission plate 7. A fixed plate 8 is fixedly connected to the top of the inner cavity of the protective shell 11. A circular plate 81 is rotatably installed on the side of the fixed plate 8 near the transmission plate 7. The circular plate 81 is driven by the motor shaft of a servo motor fixedly installed on the side of the fixed plate 8. The motor shaft is rotatably connected to the fixed plate 8. The motor shaft passes through the fixed plate 8 and is fixedly connected to the circular plate 81. A circular shaft 82 is fixedly connected to the side of the circular plate 81 near the transmission plate 7. The circular shaft 82 is eccentrically distributed on the side of the circular plate 81, that is, the circular shaft 82 and the circular plate 81 are not on the same axis. A roller 83 is rotatably installed on the outer side of the circular shaft 82. The roller 83 is inserted into the transmission groove 71 and is in rolling connection with the transmission groove 71.

[0039] When the swing blower mechanism needs to swing and blow air onto the mold body 4, the motor shaft of the servo motor drives the circular plate 81 to rotate. The circular plate 81 drives the roller 83 to rotate through the circular shaft 82, causing the roller 83 to roll along the transmission groove 71. The roller 83 pushes the transmission plate 7 to swing back and forth. The transmission plate 7 drives the semi-circular air guide pipe 6 to swing back and forth. The semi-circular air guide pipe 6 drives the slide rail 67 to slide back and forth along the slide block 66, so that the semi-circular air guide pipe 6 can swing back and forth stably.

[0040] The semi-circular air guide duct 6 drives the second air knife 64 to swing back and forth, so that the hot air blown out by the second air knife 64 covers the surface of the mold body 4. At the same time, the hot air blown out by the second air knife 64 has a sweeping effect, and the airflow direction of the hot air swings left and right and changes continuously, producing a stirring and peeling effect, which is more conducive to blowing out and blowing away the water in the depressions on the surface of the mold body 4, thereby improving the drying effect of the mold body 4.

[0041] Working principle: When the mold body 4 needs to be dried, the dried mold body 4 is removed through the loading and unloading port, and a new mold body 4 to be dried is installed. At this time, the lower end of the mold body 4 is in contact with the support mechanism, and the support mechanism supports and limits the mold body 4. Initially, the lower end of the first support component contacts the top plate of the first semi-annular plate 5. At this time, the first support component supports and limits the mold body 4. The rotating disk 13 is driven to rotate intermittently by the electric turntable 12, so that the mold body 4 can be continuously installed and disassembled. When the rotating disk 13 rotates, it drives the mold body 4 to rotate synchronously through the support mechanism. At this time, the mold body 4 passes through the bottom of the swing blower mechanism and the side of the first air knife 61. The bottom of the mold body 4 is dried by blowing air through the first air knife 61. The drive mechanism drives the mold body 4 to rotate synchronously. The semi-circular air guide 6 oscillates back and forth, and drives the slide rail 67 to slide back and forth along the slide block 66. This allows the semi-circular air guide 6 to stably drive multiple second air knives 64 to oscillate back and forth, so that the hot air blown out by the second air knives 64 can wrap around the surface of the mold body 4. At the same time, the hot air blown out by the second air knives 64 has a sweeping effect, and the airflow direction of the hot air oscillates left and right and constantly changes, producing a stirring and peeling effect, which is more conducive to blowing out and blowing away the water in the depressions on the surface of the mold body 4, thereby improving the drying effect of the mold body 4.

[0042] When the rotating disk 13 drives the support mechanism to rotate to the intersection and overlap of the two first semi-annular plates 5 and the two second semi-annular plates 51, the first support assembly and the second support assembly simultaneously support the mold body 4. The rotating disk 13 continues to rotate, causing the support mechanism to move away from the top of the first semi-annular plate 5. At this time, the first support assembly separates from the first semi-annular plate 5. Under the action of the first return spring 26, the first support assembly releases its support on the mold body 4, while the second support assembly continues to support the mold body 4. This allows the first support assembly and the second support assembly to alternate stably, preventing the mold body 4 from shaking or shifting.

[0043] The first support component and the second support component support the mold body 4 at different positions. During the movement of the mold body 4, the mold body 4 can be thoroughly dried by the cooperation of multiple swing blower components and multiple first air knives 61, which greatly improves the drying efficiency and effect.
