Furthermore, the existing upper edge finishing components have a large load, making it difficult to guarantee movement stability. Additionally, the pressure of the existing edge-trimming disc is achieved by compressing a spring through screws, making the disc pressure difficult to quantify and requiring judgment based on the operator's experience.

[0015] 1. This utility model, by setting up a forward and backward disc pressure adjustment component, an upper disc pressure adjustment component, and a lower disc pressure adjustment component, allows for the following changes when changing the curvature: the trimming knife lifting motor at the upper scraping edge moves upward, while the forward and backward trimming knife motor moves backward, returning to a starting point; then, starting from this starting point again, the trimming knife lifting motor moves downward, and the forward and backward trimming knife motor moves forward, ultimately aligning the other cutting edge of the knife with the sheet metal, thus achieving knife changing operation. This improves the speed of fine trimming knife replacement and increases work efficiency. The same principle applies to changing the curvature of the multi-blade trimming knife at the lower scraping edge. By setting up a buffer, when the sheet metal passes over the upper disc, the entire upper scraping component needs to be lifted up, requiring more gravity to be overcome. Adding a buffer prevents the upper scraping component from being too heavy and damaging the sheet metal, making the upper scraping action more stable and reducing the servo load. The pressure of the front and rear disc cylinders is adjusted by a pressure regulating valve to achieve a suitable pressure on the sheet metal from the upper and lower discs, and the adjustment is quantitative based on the pressure gauge reading.

[0018] This utility model relates to a servo-adjustable precision repair device, such as... Figure 1-7As shown, the device includes a mounting base 1. An upper edge finishing component is located on one side of the mounting base 1, and a lower edge finishing component is located on the other side. A pressure beam guide rail 2 for transporting sheet metal is located at the front end of the mounting base 1. The upper edge finishing component includes an upper disc pressure adjustment component 3, a forward / backward disc pressure adjustment component 4, a trimming blade forward / backward component 5, and a trimming blade lifting component 6. The lower edge finishing component includes a lower disc pressure adjustment component 7, a forward / backward disc pressure adjustment component 4, a trimming blade forward / backward component 5, and a trimming blade lifting component 6. The trimming blade lifting components 6 corresponding to the upper and lower edge finishing components are respectively connected to the upper finishing motor 8 and the lower finishing motor 9. The upper and lower precision repair motors 8 and 9 are equipped with multi-bladed precision repair blades 10 that slide against the sheet metal at their output ends. The upper disc pressure regulating assembly 3 is mounted to the pressure beam guide rail 2 via a buffer. The forward and backward disc pressure regulating assembly 4 is equipped with a template 14 that slides against the side of the sheet metal. The front ends of the upper and lower disc pressure regulating assemblies 3 and 7 are respectively equipped with discs 12 that slide against the sheet metal. The upper and lower disc pressure regulating assemblies 3 and 7 are powered by cylinders, have pressure values ​​set by pressure regulating valves, and have pressure control achieved by monitoring the discs 12 via pressure gauges. A mounting base 1 is provided as... The main body of the device has a plate inside the pressure beam guide rail 2. A track drive mechanism is installed inside the pressure beam guide rail 2, which presses and fixes the plate and moves it within the guide rail 2. The upper edge finishing component and the lower edge finishing component correspond to the upper and lower edges of the plate, respectively. The upper disc pressure adjustment component 3 moves the upper edge disc 12 vertically to adjust the pressure between the upper edge disc 12 and the plate. The lower disc pressure adjustment component 7 moves the lower edge disc 12 vertically to adjust the pressure between the lower edge disc 12 and the plate. The forward and backward disc pressure adjustment component 4 moves the upper and lower edge discs 12... The trimmer moves horizontally and adjusts its position. The trimmer blade advance / retract assembly 5 and the trimmer blade lifting assembly 6 move horizontally and vertically, respectively. The trimmer blade lifting assembly 6 is installed with the upper finishing motor 8 and the lower finishing motor 9. When the trimmer blade advance / retract assembly 5 and the trimmer blade lifting assembly 6 are started, the upper finishing motor 8 and the lower finishing motor 9 move horizontally and vertically. By setting a multi-blade finishing blade 10, the blade of the multi-blade finishing blade 10 has multiple R angles. When changing the curvature, the trimmer blade lifting motor 61 at the upper scraping edge moves up, and the trimmer blade advance / retract motor 51, which controls the advance and retract, moves backward and returns to an origin.Starting from this origin again, the trimming knife lifting motor 61 is controlled to move downwards, and the trimming knife forward / backward motor 51 is controlled to move forwards, ultimately aligning the other cutting edge of the knife with the sheet metal, thus realizing the knife change operation. This improves the speed of fine trimming knife replacement and increases work efficiency. The same principle applies to the replacement arc of the multi-blade trimming knife for lower edge scraping. By setting a buffer, when the sheet metal passes over the upper disc 12, the entire upper edge scraping assembly needs to be lifted up, requiring more gravity to be overcome. Adding a buffer can prevent the upper edge scraping assembly from being too heavy and damaging the sheet metal, making the upper edge scraping action more stable and reducing the servo load. The pressure of the front and rear disc cylinders is adjusted by the pressure regulating valve to achieve a suitable pressure on the sheet metal from the upper and lower discs. The adjustment is quantitative based on the pressure gauge reading, thereby solving the problem that this utility model aims to solve.

The telescopic rod is installed with the pressure beam guide rail 2. Activating the upper disc pressure regulating cylinder 33 drives the first slide block 32 to move vertically along the first vertical slide rail 31. By setting a gas spring 11, when the plate passes the upper disc 12, the entire upper scraping assembly needs to be lifted up, which requires overcoming more gravity. Adding a gas spring 11 can prevent the upper scraping assembly from being too heavy and damaging the plate, making the upper scraping action more stable, reducing the servo load, and ensuring motion stability. By setting a buffer spring 13, with both ends of the buffer spring 13 installed with the first slide block 32 and the pressure beam guide rail 2 respectively, the vibration of the first slide block 32 in the vertical direction is reduced, further improving motion stability.

The telescopic end of the lower disc pressure regulating cylinder 73 drives the telescopic rod to move. The telescopic rod is installed at the bottom of the second slide block 72, which drives the second slide block 72 to move vertically along the second vertical slide rail 71, thereby driving the disc 12 to move vertically. The lower disc pressure regulating cylinder 73 is connected to a pressure gauge and a pressure regulating valve. The pressure of the lower disc pressure regulating cylinder 73 is adjusted by the pressure regulating valve to make the pressure of the lower disc on the material reach a suitable state.

By setting the advance and retraction slide block 41, the advance and retraction cylinder 42, and the mounting plate 43, the extension end of the advance and retraction cylinder 42 drives the extension rod to move. The extension rod is installed with the first slide block 32, so that the advance and retraction cylinder 42 and the mounting plate 43 move horizontally along the advance and retraction slide block 41, thereby driving the template 14 to move vertically. The advance and retraction cylinder 42 uses a pressure regulating valve to set the pressure value, and the pressure gauge monitors the template 14 in real time to achieve pressure control.

[0022] In an embodiment of this utility model, the trimming knife advance / retreat assembly 5 includes a trimming knife advance / retreat motor 51, an advance / retreat module 52, and a first fixing plate 53.

The telescopic end of the trimming knife advance / retreat motor 51 is connected to the inside of the advance / retreat module 52 in the horizontal direction through a ball screw. By setting the trimming knife advance / retreat motor 51, the advance / retreat module 52, and the first fixing plate 53, the output end of the trimming knife advance / retreat motor 51 drives the ball screw to drive inside the advance / retreat module 52, thereby driving the advance / retreat module 52 to move along the length direction of the guide posts.

[0023] In an embodiment of this utility model, the trimming knife lifting assembly 6 includes a trimming knife lifting motor 61, a lifting module 62, and a second fixing plate 63. The second fixing plate 63 is disposed at one end of the forward / reverse module 52 and is perpendicular to the two first fixing plates 53. Two guide posts are symmetrically arranged in the vertical direction inside the second fixing plate 63. The two guide posts are slidably connected to both ends inside the forward / reverse module 52 in the vertical direction, and the ends of the two guide posts away from the second fixing plate 63 are slidably connected to the inside of the lifting module 62. The trimming knife lifting motor 61 is installed on the outside of the forward / reverse module 52 through a motor fixing seat. The telescopic end of the trimming knife lifting motor 61 is connected to the lifting module 62 in the vertical direction through a ball screw. By setting the trimming knife lifting motor 61, the lifting module 62, and the second fixing plate 63, the output end of the trimming knife lifting motor 61 drives the ball screw to drive inside the lifting module 62, thereby causing the lifting module 62 to move along the length direction of the guide posts.

[0024] In this embodiment of the utility model, the lifting module 62 corresponding to the upper edge finishing component is located below the forward and backward module 52. The upper finishing motor 8 is installed at the bottom of the lifting module 62 in an inclined manner, with the inclination direction from the pressure beam guide rail 2 towards the mounting base 1.

By setting the template 14, the edge banding is pressed between the template 14 and the plate to ensure the stability of the edge banding.

[0026] In this embodiment of the utility model, a waste discharge pipe 15 is installed on the mounting plate 43, covering the outside of the multi-blade finishing knife 10. The discharge end of the waste discharge pipe 15 corresponding to the finishing component at the upper edge faces upward, and the discharge end of the waste discharge pipe 15 corresponding to the finishing component at the lower edge faces downward. A fan and a collection container are installed at the end of the waste discharge pipe 15 away from the multi-blade finishing knife 10. By setting the waste discharge pipe 15, the waste discharge pipe 15 covers the outside of the multi-blade finishing knife 10. The fan generates suction at one end of the waste discharge pipe 15, which facilitates the transfer of ribbons and dust to the collection container, avoiding affecting the next processing or splashing to other workstations and affecting the operation of other components.

[0027] In this embodiment of the utility model, the multi-blade finishing knife 10 has three blade sizes: R2.5, R2, and R1.5. By setting the multi-blade finishing knife 10 to have three blade sizes (R2.5, R2, and R1.5), it is more convenient than the conventional multi-blade finishing knife 10 which only has one type of curvature, and it eliminates the trouble of changing tools.

[0028] In operation, the sheet metal is first placed inside the pressure beam guide rail 2 and pressed down by the pressure beam. The sheet metal is then transported along the pressure beam guide rail 2 by the track. The upper finishing motor 8 and lower finishing motor 9 are started, driving the multi-blade finishing blade 10 to rotate. The sheet metal passes through the upper and lower edge discs 12, and the multi-blade finishing blade 10 completes the finishing work on the upper and lower edges of the sheet metal. When changing the curvature, the trimming blade lifting motor 61 at the upper scraping edge moves upward, and the trimming blade forward / backward motor 51, which controls the forward and backward movement, moves backward, returning to a starting point. Then, starting from this starting point again, the trimming blade lifting motor 61 is moved downward, and the trimming blade forward / backward motor 51 is moved forward, ultimately aligning the other cutting edge of the blade with the sheet metal, thus achieving blade changing operation. This improves the speed of finishing blade replacement and increases work efficiency. Similarly, when changing the curvature of the edge trimming knife, the vibration is buffered by the gas spring 11 and the buffer spring 13 when the sheet passes through the upper disc 12. The upper disc pressure adjustment component 3 is used to drive the upper edge disc 12 to move vertically and adjust the pressure between the upper edge disc 12 and the sheet. The lower disc pressure adjustment component 7 is used to drive the lower edge disc 12 to move vertically and adjust the pressure between the lower edge disc 12 and the sheet. The forward and backward disc pressure adjustment component 4 is used to adjust the pressure of the template 14 on the sheet, so that the pressure of the template 14 on the sheet reaches a suitable state. The adjustment is quantitative according to the reading of the pressure gauge. The exhaust fan is started. The exhaust fan generates suction at the discharge end of the waste discharge pipe 15 to facilitate the discharge of ribbons and dust, so as to avoid affecting the next processing or splashing to other workstations and affecting the operation of other parts.
