Description

Technical Field

[0001] This invention relates to the field of alloy steel casting technology, and more specifically, to a coating device and coating method for processing alloy steel castings. Background Technology

[0002] Alloy steel castings refer to parts or products cast from alloy steel. Alloy steel is a type of steel made by adding one or more alloying elements to carbon steel. The addition of these alloying elements can significantly improve the mechanical, physical, and chemical properties of the steel, such as increasing strength, hardness, wear resistance, corrosion resistance, and thermal stability, thereby meeting the special performance requirements of castings in different industrial fields. In the production process of alloy steel castings, coating technology, as an important surface treatment process, can protect alloy steel castings during transportation, preventing the surface of the castings from being scratched, impacted, and corroded by environmental factors such as oxidation and corrosion.

[0003] According to patent document CN109109306A, a coating device for processing alloy steel castings includes a device base. Two sets of strip-shaped grooves are fixedly installed at the top of the device base. Two sets of sliding seats are slidably connected within each strip-shaped groove. A first conveying plate and a second conveying plate are respectively installed at the top of the two sets of sliding seats. Racks are installed on the sidewalls of the first and second conveying plates that are close to each other. Two sets of support seats are installed at the top of the first conveying plate, and limit frames are installed at the top of the support seats. A rotating gear is provided between the two sets of strip-shaped grooves. The rotating rod includes a rod body, one end of which is bent to form a curved portion. This curved portion is rotatably connected to a fixing component for fixing to a cabinet. The other end of the rod body is provided with a hinge shaft for rotatably connecting to a tray. Compared with existing equipment, this invention can alternately convey alloy steel castings, saving manpower and resources without reducing work efficiency. Moreover, the entire device is intelligent, easy to operate and use.

[0004] In the process of coating alloy steel castings, the usual operation method is to place the alloy steel castings stably on a conveyor belt, and then, through the continuous operation of the conveyor belt, gradually transport the alloy steel castings to a dedicated coating area for coating. However, when using the traditional conveyor method for coating, some technical problems are often encountered. For example, the alloy steel castings may shift position during the conveying process, causing the castings to fail to accurately reach the predetermined coating position. In addition, due to the imprecise control of the movement trajectory and speed of the conveyor belt, the coating material may be unevenly distributed on the surface of the casting, thus affecting the overall quality and final effect of the coating. These problems not only reduce the efficiency of the coating process, but may also have an adverse effect on the performance and appearance of the product. Summary of the Invention

The outer walls of the two H-shaped pressure plates 221 are set on the inner side of the two side plates 2211. Springs 227 are fitted on one side of the outer wall of the two columnar uprights 226 on the inner side of the two sets of columnar upright guide blocks 2212. When coating alloy steel castings, the worker first places the castings on top of the vacuum adsorption plate 128. At this time, the vacuum adsorption control box 127 is activated, creating negative pressure on the vacuum adsorption plate 128 through its internal vacuum system, firmly adsorbing the alloy steel castings onto the top of the vacuum adsorption plate 128 to ensure that the castings do not shift during the coating process. Then, the dual-axis motor 214 is started. After starting, the dual-axis motor 214 drives two rotating rods 215 to rotate synchronously. Since the rotating rods 215 are fixedly connected to the second transmission disc 216, the second transmission disc 216 also rotates, transmitting power to the two rear transmission discs 1112 via the third track 217. The rotation of the two rear transmission discs 1112 drives the two front transmission discs 1112 to rotate via the two tracks 1113. When the two sets of transmission discs 1112 rotate, they in turn drive the two sets of transmission wheels 1110 to rotate via the two sets of columnar transmission rods 1111, and the rotation of the two sets of transmission wheels 1110 drives the two second tracks 1112 to rotate. 114 rotates cyclically. Since the connecting blocks 122 in the middle of the left and right sides of the moving part base plate 121 are fixedly connected to the front side of the top outer wall of the two second tracks 1114, when the second tracks 1114 rotate, they will drive the moving part base plate 121 to move horizontally to the rear side along the guide rod 114. During the movement of the moving part base plate 121, its top is connected to the moving part top plate 125 through the rectangular side plate 124, as well as the vacuum adsorption control box 127, vacuum adsorption plate 128 and alloy steel casting above it. They will also move synchronously. At the same time, the two tracks 1113 rotate, thereby driving the two side plates 2211 to move forward. When the two side plates 2211 move forward, they will synchronously drive the coating assembly 22 connected to them to move forward as a whole. Since the coating assembly 22 and the moving assembly 12 move synchronously, when the moving assembly 12 moves to the last side of the two slides 112 opened on the top plate 111, the bottom of the H-shaped pressure plate 221 is aligned with the alloy steel casting fixed on the top of the vacuum adsorption plate 128. After alignment, the dual-axis motor 214 stops starting, and simultaneously the electric push rod 2215 starts. Once started, the output end of the electric push rod 2215 pushes the push-pull top plate 2210 downwards. Since the push-pull top plate 2210 is fixedly connected to the push-pull plate 229, and the push-pull plate 229 is connected to the columnar upright 226 via the push-pull plate side plate 228, this drives the entire H-shaped pressure plate 221 downwards. During the downward movement of the H-shaped pressure plate 221, the tension control rollers 223, which are rotatably connected to the inner sides of its front and rear sides, first contact the film material 2116 and apply a certain pressure to it, ensuring that the film material 2116 can be smoothly adhered to the surface of the alloy steel casting. As the H-shaped pressure plate 221 continues to move downwards, the film material 2116 is gradually pressed onto the alloy steel casting. Simultaneously, because the middle of the H-shaped pressure plate 221 has a hollow design, it does not exert excessive pressure on the casting, ensuring the quality of the coating. When the H-shaped pressure plate 221 moves down to the predetermined position, the electric push rod 2215 stops starting. At this time, the film material 2116 has been tightly attached to the surface of the alloy steel casting, completing the coating process. The excess film material edges are precisely cut off by the rectangular cutting blade 222 at the bottom of the H-shaped pressure plate 221 to ensure that the film material on the surface of the alloy steel casting is flat and dimensionally accurate. After cutting, the electric push rod 2215 starts in reverse, driving the push-pull top plate 2210 to move upward, thereby causing the H-shaped pressure plate 221 to rise and detach from the coated alloy steel casting. The dual-axis motor 214 starts in reverse to drive the moving component 12 and reset the moving component 12. After the moving component and the coating component are reset, the operator closes the vacuum adsorption control box 127, and the vacuum adsorption plate 128 stops generating negative pressure. At this time, the coated alloy steel casting can be easily removed from the top of the vacuum adsorption plate. The motor 2113 starts, driving the take-up roller 2114 and take-up roller 2115 to rotate, winding the used film material 2116 off the film material roller 2111, preparing for the next coating.

[0022] In addition, the present invention also relates to a coating method for a coating apparatus for processing alloy steel castings, comprising the following steps: Step 1: Place the alloy steel casting on top of the vacuum adsorption plate 128, start the vacuum adsorption control box 127 to generate negative pressure on the vacuum adsorption plate 128, and firmly adsorb the alloy steel casting. Step 2: Start the dual-axis motor 214, which drives the two rotating rods 215 to rotate synchronously, thereby causing the second transmission disc 216 to rotate, and transmitting power to the two transmission discs 1112 on the rear side through the third track 217; Step 3: The two rear transmission discs 1112 rotate, which drives the two front transmission discs 1112 to rotate through the two tracks 1113, thereby driving the two sets of transmission wheels 1110 to rotate, so that the two second tracks 1114 rotate cyclically. Step 4: The second track 1114 rotates, causing the moving part base plate 121 to move horizontally to the rear along the guide rod 114. At the same time, the two tracks 1113 rotate, causing the two side uprights 2211 to move forward, so that the film covering assembly 22 and the moving assembly 12 move synchronously. Step 5: When the moving component 12 moves to the last side of the two slides 112 opened in the top plate 111, the bottom of the H-shaped pressure plate 221 is aligned with the alloy steel casting fixed to the top of the vacuum adsorption plate 128, and the dual-axis motor 214 stops starting. Step 6: The electric push rod 2215 is started, pushing the push-pull top plate 2210 to move downward, which in turn moves the H-shaped pressure plate 221 downward, so that the tension control roller 223 contacts the film material 2116, pressing the film material 2116 onto the alloy steel casting, and cutting off the excess film material edges through the rectangular cutting blade 222 at the bottom of the H-shaped pressure plate 221.

[0023] Working principle of this invention: When performing a coating operation on alloy steel castings, the operator first places the alloy steel casting on top of the vacuum adsorption plate 128. At this time, the vacuum adsorption control box 127 is activated, and its internal vacuum system creates a negative pressure on the vacuum adsorption plate 128, thereby firmly adsorbing the alloy steel casting onto the top of the vacuum adsorption plate 128. Subsequently, the dual-axis motor 214 is activated. After the dual-axis motor 214 is activated, it drives the two rotating rods 215 to rotate synchronously. Since the rotating rods 215 are fixedly connected to the second transmission disk 216, the second transmission disk 216 rotates accordingly, and transmits power to the two rear transmission disks 1112 through the third track 217. The two rear transmission disks 1112 rotate, and then drive the two front transmission disks 1112 through the two tracks 1113. When the two sets of transmission discs 1112 rotate, they drive the two sets of transmission wheels 1110 to rotate via the two sets of columnar transmission rods 1111. The rotation of the two sets of transmission wheels 1110 then drives the two second tracks 1114 to rotate cyclically. Since the connecting blocks 122 at the center of the left and right sides of the moving part base plate 121 are fixedly connected to the front side of the top outer wall of the two second tracks 1114, when the second tracks 1114 rotate, they drive the moving part base plate 121 to move horizontally to the rear along the guide rod 114. During the movement of the moving part base plate 121, the moving part top plate 125 connected to it via the rectangular side plate 124, as well as the vacuum adsorption control box 127, vacuum adsorption plate 128, and alloy steel casting above it, will move synchronously. At the same time, the two tracks... 1113 rotates, causing the two side plates 2211 to move forward. When the two side plates 2211 move forward, they will synchronously drive the coating assembly 22 connected to them to move forward as a whole. Since the coating assembly 22 moves synchronously with the moving assembly 12, when the moving assembly 12 moves to the last side of the two sliding grooves 112 opened on the top plate 111, the bottom of the H-shaped pressure plate 221 aligns with the alloy steel casting fixed to the top of the vacuum adsorption plate 128. After alignment, the dual-axis motor 214 stops starting, and at the same time, the electric push rod 2215 starts. After the electric push rod 2215 starts, its output end pushes the push-pull top plate 2210 to move downward. Since the push-pull top plate 2210 is fixedly connected to the push-pull plate 229, and the push-pull plate 229 is connected to the columnar upright plate 228 through the push-pull plate side plate 228, The connecting rod 226 drives the entire H-shaped pressure plate 221 downwards. During the downward movement of the H-shaped pressure plate 221, the tension control rollers 223, which are rotatably connected to the inner sides of its front and rear sides, first contact the film material 2116 and apply a certain pressure to the film material 2116, ensuring that the film material 2116 can be smoothly adhered to the surface of the alloy steel casting. As the H-shaped pressure plate 221 continues to move downwards, the film material 2116 is gradually pressed onto the alloy steel casting. At the same time, because the middle of the H-shaped pressure plate 221 has a hollow design, it will not put excessive pressure on the casting, ensuring the coating quality. When the H-shaped pressure plate 221 moves down to the predetermined position, the electric push rod 2215 stops starting. At this time, the film material 2116 has been tightly adhered to the surface of the alloy steel casting, completing the coating process. Afterwards...The excess film edge after coating is precisely trimmed by the rectangular cutting blade 222 at the bottom of the H-shaped pressure plate 221. After trimming, the electric push rod 2215 starts in reverse, driving the push-pull top plate 2210 to move upward, thereby raising the H-shaped pressure plate 221 and detaching it from the coated alloy steel casting. Then, the dual-axis motor 214 starts in reverse, resetting the transmission moving component 12 and the moving component 12. After the moving component and the coating component are reset, the operator closes the vacuum adsorption control box 127, and the vacuum adsorption plate 128 stops generating negative pressure. At this time, the coated alloy steel casting can be easily removed from the top of the vacuum adsorption plate. Subsequently, the motor 2113 starts, driving the take-up roller 2114 and the take-up roller 2115 to rotate, winding the used film 2116 off the film roller 2111, preparing it for the next coating.
