Description

Technical Field

[0001] This application relates to the field of sheet metal processing technology, and more specifically, to a sheet metal pre-milling mechanism. Background Technology

[0002] In the production of panel furniture, edge banding strips and adhesives are used to seal the edges of the panels due to factors such as durability and aesthetics. Since the processed surfaces may be tilted or damaged during material cutting or handling, resulting in unsatisfactory edge banding effects, pre-milling is necessary to straighten the edge banding surface.

[0003] Pre-milling is a process that uses a milling cutter to mill the edge banding surface of the board, ensuring that the surface to be banded is flat. After milling by the pre-milling mechanism, various defects in the processed surface can be removed, achieving the best edge banding condition. The quality of the pre-milling will affect the flatness of the edge banding surface. A flat edge banding surface can fully adhere to the edge banding strip; conversely, if the edge banding surface has protrusions, depressions, or tilts, the edge banding strip will not adhere well, leading to board quality problems.

[0004] In existing technology, the pre-milling mechanism has two horizontal milling cutters. These cutters are controlled to mill the sheet metal to a specific depth. During milling, the milling depth of the pre-milling mechanism cannot exceed 1mm. However, in actual milling operations, tasks requiring large-area straightening of the sheet metal, where the milling depth exceeds 1mm, are often encountered. Existing pre-milling mechanisms have insufficient milling depth. To meet the demands of large-area straightening, the milling depth of the pre-milling mechanism needs to be increased. However, this method of increasing the milling depth is not suitable for the applicable working scenarios of pre-milling machines. It will accelerate the wear of the milling cutters, affecting their service life, increasing production costs, and leading to poor pre-milling results, which can easily affect the edge banding effect and increase the defect rate. Utility Model Content

[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0053] The plate pre-milling mechanism provided in this application is intended to solve at least one technical problem existing in the prior art.

[0054] This application provides a sheet metal pre-milling mechanism, such as... Figures 1-19 As shown, the pre-milling mechanism for the sheet metal includes a horizontal milling module with a horizontal milling cutter 47 and a vertical milling module with a first vertical milling cutter 45 and a second vertical milling cutter 46. The horizontal milling module and the vertical milling module are used to mill the same edge sealing surface of the sheet metal. The vertical milling module is located on the sheet metal-free side of the horizontal milling module. During the milling process, the first vertical milling cutter 45 is located above the edge sealing surface, and the second vertical milling cutter 46 is located below the edge sealing surface. The horizontal milling cutter 47 is located on the same horizontal plane as the sheet metal and is located on the side of the edge sealing surface away from the sheet metal.

[0055] Optionally, the first vertical end mill 45 and the second vertical end mill 46 can be crushing end mills, and the second vertical end mill 46 can be disposed between the first vertical end mill 45 and the horizontal end mill 47.

[0056] Optionally, during the milling process, the sheet metal is first milled by a horizontal milling cutter 47, and then by a second vertical milling cutter 46 and a first vertical milling cutter 45 in sequence. Specifically, the milling operation of the sheet metal can be performed in two ways. The first way: A horizontal milling cutter 47 at the front end mills the sheet metal to a certain depth, and the two vertical milling cutters behind it can further mill the sheet metal, using three milling cutters to mill the sheet metal to a specific depth. The second way: The horizontal milling cutter 47 first mills the front part of the sheet metal surface to be sealed to a specific depth, and then the two vertical milling cutters mill the remaining part of the surface to be sealed to a specific depth, using three milling cutters to mill the sheet metal to a specific depth. Compared with existing pre-milling mechanisms, the mechanism of this application can achieve milling of a greater depth in the sheet metal.

[0057] In one embodiment, the horizontal milling module includes a first drive motor 38, which is connected to a horizontal milling cutter 47. The first drive motor 38 drives the horizontal milling cutter 47 to rotate, thereby realizing the horizontal milling of the plate.

[0058] Optionally, the plate pre-milling mechanism includes a milling cutter base 5 and a translation module with a first base 43, a first slider 42, a first slide rail 41 and a first drive unit. The horizontal milling module and the vertical milling module are fixed on the milling cutter base 5. The bottom of the milling cutter base 5 is connected to the top of the first slider 42. The bottom of the first slider 42 is slidably nested on the first slide rail 41. The first slide rail 41 is fixed on the first base 43. The first drive unit is fixed on one side of the first base 43, and the drive end of the first drive unit is fixedly connected to the milling cutter base 5.

[0059] In one embodiment, there can be two first slide rails 41 arranged side by side. There can be four first sliders 42, with two sliders 42 on each first slider 42. The linear movement of the milling cutter base 5 is achieved by sliding the first sliders 42 on the first slide rails 41.

[0060] Optionally, the first drive unit may include a first drive cylinder 16, a first cylinder seat 17, and a first cylinder adjusting block 28. The first drive cylinder 16 is fixed to the side of the first cylinder seat 17, and the side of the first cylinder seat 17 away from the first drive cylinder 16 is opposite to the first cylinder adjusting block 28. The first cylinder adjusting block 28 is fixed to the milling cutter base 5, and the output shaft of the first drive cylinder 16 passes through the first cylinder seat 17 and is fixed to the first cylinder adjusting block 28. The movement of the milling cutter base 5 is achieved by extending and retracting the output shaft driven by the first drive cylinder 16.

[0061] In one embodiment, there may be two first drive units. The first cylinder adjustment block 28 can be fixed to the side of the milling cutter base 5 by bolts, and one end of the output shaft of the first drive cylinder 16 is connected to the first cylinder adjustment block 28 by threads.

[0062] Optionally, the translation module further includes a first counting unit with a first counter, a first fixed base 18, and a first fixed block 49. The first counter has a first adjusting shaft 19 for counting. The first fixed base 18 is fixed to the side of the milling cutter base 5 and is located on the same side of the milling cutter base 5 as the first driving unit. The first fixed block 49 is fixed to the side of the first base 43 near the milling cutter base 5. The first fixed base 18 has a screw hole that matches the first adjusting shaft 19. The first adjusting shaft 19 is screwed in the screw hole. One end of the first adjusting shaft 19 passes through the first fixed base 18 and is opposite to the first fixed block 49.

[0063] In one embodiment, the first counter can be set between two first drive units, and the first fixed base 18 is set between the movement strokes of the first adjusting shaft 19, thereby limiting the stroke of the milling cutter base 5 through the first adjusting shaft 19 and the first fixed block 49.

[0064] Optionally, such as Figure 11 , Figure 12 As shown, the first counter also includes a first housing 20, a first counting shaft 56, a first fixing pad 57, and a first adjusting sleeve 58. A first locking pad 59 is also provided on the side of the first fixing base 18 away from the first counter, and the first housing 20 is fixed to the first fixing base 18. The first fixing base 18 and the first fixing pad 57 are fixed together with screws (which can be flat cup screws), thereby restricting the axial movement of the first adjusting sleeve 58 passing through the first fixing pad 57 and the first fixing base 18. The first fixing pad 57 has four circumferentially arranged threaded holes, which correspond to the threaded holes on the first fixing base 18; the central hole of the first fixing pad 57 allows one end of the first adjusting sleeve 58 to pass through, while the annular protrusion at one end of the first adjusting sleeve 58 cannot pass through the central hole. The first fixing base 18 has a space specifically for accommodating this annular structure. After passing one end of the first adjusting sleeve 58 through the center hole of the first fixing pad 57, the first fixing pad 57 is then fixed to the first fixing seat 18 with bolts. The first adjusting sleeve 58 is then confined within the space formed by the first fixing pad 57 and the first fixing seat 18, so that the first adjusting sleeve 58 cannot move axially, but the first adjusting sleeve 58 can rotate.

[0065] The hole on the side of the first adjusting sleeve 58 corresponds to the elongated hole on the side of the first adjusting shaft 19. A pin passes through the hole in the first adjusting sleeve 58 and the elongated hole in the first adjusting shaft 19, allowing them to rotate synchronously and enabling the first adjusting shaft 19 to move axially relative to the first adjusting sleeve 58. The external thread on the first adjusting shaft 19 corresponds to the internal thread of the first housing 20 and the first locking washer 59. The first adjusting shaft 19 is screwed into the first housing 20 and the first locking washer 59, and the threads are tightened by tightening the screws fixed to the first locking washer 59 to eliminate the clearance between the internal and external threads (the threaded fit between the first adjusting shaft 19 and the first fixed seat 18) and prevent loosening. This avoids slight rotation of the first adjusting shaft 19 due to external force during machine operation, which would affect the extension length of the first adjusting shaft 19 and ultimately the cutting accuracy of the entire machine. The first counting shaft 56 is located on the side of the first housing 20 away from the first fixed seat 18, and the diameter of the first counting shaft 56 is larger than the inner diameter of the through hole in the first housing 20 that accommodates the first adjusting shaft 19. The first counting shaft 56 is hollow and fixed to the first adjusting sleeve 58 by screws, preventing the first housing 20 from moving axially. The first counting shaft 56 can rotate synchronously with the first adjusting sleeve 58; a boss on the first housing 20 extends into the first fixed seat 18, preventing the first housing 20 from rotating; rotation of the first counting shaft 56 will change the reading of the first counter. When the first adjusting shaft 19 is rotated, the first adjusting shaft 19, the first adjusting sleeve 58, and the first counting shaft 56 rotate synchronously, ultimately changing the reading of the first counter.

[0066] In one embodiment, to adjust the forward and backward stroke of the pre-milling mechanism: the extension of the first adjusting shaft 19 on the first counter changes when the first adjusting shaft 19 is rotated. The first counter is fixed to the milling cutter base 5 by the first fixed seat 18, so the first adjusting shaft 19 can slide back and forth with the milling cutter base 5. When the output shaft of the first drive cylinder 16 extends, it pushes the first cylinder adjusting block 28 forward. The first cylinder adjusting block 28 is fixed to the milling cutter base 5, so the milling cutter base 5 slides forward, and the first adjusting shaft 19 also slides forward together until the end of the first adjusting shaft 19 hits the first fixed block 49, at which point the milling cutter base 5 stops sliding. Reducing the extension of the first adjusting shaft 19 causes it to travel a longer distance before hitting the first fixed block 49, thus increasing the stroke of the first drive cylinder 16 shaft. Conversely, increasing the extension of the first adjusting shaft 19 causes it to travel a shorter distance before hitting the first fixed block 49, thus shortening the stroke of the first drive cylinder 16 shaft. Therefore, the forward and backward stroke of the first drive cylinder 16 shaft can be controlled by rotating the first adjusting shaft 19 on the first counter. The stroke of the first drive cylinder 16 shaft determines the stroke of the milling cutter base 5, allowing for visual adjustment of the feed amount of the entire milling cutter mechanism.

[0067] Optionally, the milling cutter base 5 includes a base unit and a groove unit with a first groove. The groove unit is vertically fixed to one end of the base unit, and the driving end of the first driving unit is fixedly connected to the base unit. The first groove is vertically arranged on the side of the groove unit facing the base unit. The vertical milling module includes a first vertical driving unit connected to the first vertical milling cutter 45 and a second vertical driving unit connected to the second vertical milling cutter 46. The plate pre-milling mechanism also includes a lifting module with a first slide 6 and a second slide 14. One side of the first slide 6 is slidably fixed to the first groove, and the side of the first slide 6 away from the first groove is fixedly connected to the second slide 14. The first vertical driving unit is fixed to the first slide 6, and the second vertical driving unit is fixed to the second slide 14.

[0068] Optionally, the lifting module further includes a second counting unit with a second counter and a second fixed base 3. The second counter includes a second adjusting shaft 1 for counting. The second fixed base 3 is fixed to the top of the slide unit and opposite to the first slide. The second counter is installed on the side of the second fixed base 3 away from the slide unit. The second adjusting shaft 1 is threaded to the second fixed base 3, and one end of the second adjusting shaft 1 passes through the second fixed base 3 and extends into the first slide. The slide unit includes a first adjusting block 48, which is embedded in the first slide and connected to the first slide seat 6 on one side. The top of the first adjusting block 48 is rotatably connected to the end of the second adjusting shaft 1 that passes through the second fixed base 3. The first slide ensures the linear lifting of the first vertical drive unit and the second vertical drive unit.

[0069] Optionally, the structure of the second counting unit is as follows: Figure 7 , Figure 8 As shown, the second fixed seat 3 is fixed to the top of the slide unit. The second fixed seat 3 has two bearing mounting positions (one near the slide unit and one away from the slide unit), through which two thrust ball bearings 53 are installed; the external thread of the second adjusting shaft 1 corresponds to the threads on the two round nuts 54 on the side of the second fixed seat 3 near the slide unit. The end of the second adjusting shaft 1 away from the first adjusting block 48 has a ring (this ring is sleeved on the second adjusting shaft 1 and abuts against the thrust ball bearing 53) to press against the thrust ball bearing 53, and at the same time, the thread of the second adjusting shaft 1 is screwed into the two round nuts 54 to fix the two thrust ball bearings 53 and tighten the thread gap between the second adjusting shaft 1 and the round nuts 54.

[0070] The external thread of the second adjusting shaft 1 corresponds to the internal thread of the first adjusting block 48. The thread of the second adjusting shaft 1 is screwed into the first adjusting block 48. The second counting shaft 52 and the second adjusting shaft 1 are fixed together by threads. The second adjusting shaft 1 is axially fixed and can only rotate, so the second housing 2 of the second counter cannot move axially. The second counting shaft 52 can rotate synchronously with the second adjusting shaft 1. A boss on the second housing 2 extends into the second fixed seat 3, preventing the second housing 2 from rotating. The rotation of the second counting shaft 52 will change the reading of the second counter. When the second adjusting shaft 1 is rotated, the second adjusting shaft 1 and the second counting shaft 52 rotate synchronously, ultimately changing the reading of the second counter. The first adjusting block 48 can move linearly upwards and downwards due to the interaction of the threads.

[0071] Optionally, to ensure stable sliding of the first slide block 6, the first slide block 6 can be fixed to the slide groove unit through a dovetail groove structure. The first slide block 6 has a dovetail groove on the side near the slide groove unit, and the direction of the dovetail groove is the same as that of the first slide groove. A part of the slide groove unit is embedded in the dovetail groove.

[0072] In one embodiment, when adjusting the overall vertical position of the first vertical drive unit and the second vertical drive unit, the second adjustment shaft 1 is rotated to make the first adjustment block 48 move vertically. At this time, the first slide block 6 is driven to slide along the first slide groove, and the first vertical drive unit and the second vertical drive unit slide vertically upward or downward accordingly, thereby realizing the visual adjustment of the overall vertical position.

[0073] Optionally, the first vertical drive unit includes a first base plate 7 and a first driver 24. One side of the first base plate 7 is fixed to the first slide 6, and the first driver 24 is fixed to the side of the first base plate 7 away from the first slide 6. The side of the first base plate 7 close to the first slide 6 is provided with a first boss. The two ends of the first base 43 are provided with mounting holes. The first slide 6 is provided with a first mounting hole, a second mounting hole, a third mounting hole, and a fourth mounting hole at positions opposite to the mounting holes. The first mounting hole and the second mounting hole are located on the same side of the first slide 6, and the third mounting hole and the fourth mounting hole are located on the other side of the first slide 6. The first mounting hole, the second mounting hole, and the third mounting hole are elongated holes, and the fourth mounting hole is a round hole. The fourth mounting hole and the first boss are located on the same side of the first slide 6.

[0074] Optionally, the lifting module further includes a first adjusting dovetail 12 and a linear movement unit. One side of the linear movement unit is fixed to the first slide block 6, and the other side is fixedly connected to the first adjusting dovetail 12. A second slide block 14 is provided with a second slide groove on the side near the first slide block 6. The second slide groove is horizontally arranged, and the first adjusting dovetail 12 is embedded in the second slide groove. One end of the second slide block 14 is fixedly connected to the linear movement unit. The second vertical drive unit includes a second base plate 15 and a second driver 23. The second base plate 15 is fixed to the side of the second slide groove away from the first adjusting dovetail 12, and the second driver 23 is fixed to the side of the second base plate 15 away from the first adjusting dovetail 12. The structure of the second base plate 15 is the same as that of the first base plate 7, both of which are provided with multiple mounting holes, which are used to realize angle adjustment.

[0075] Optionally, the first slide 6 and the second slide 14 may also be provided with a second angle adjustment block 4. The second angle adjustment block 4 is provided with a rice-making hole. The rice-making screw passes through the rice-making hole and contacts the side of the first base plate 7 and the second base plate 15 respectively. The angle is adjusted with the assistance of the rice-making screw.

[0076] Optionally, the first driver 24 and the second driver 23 can both be servo motors or other types of driving devices that can be used to drive the milling cutter.

[0077] In one embodiment, such as Figure 16 , Figure 17 As shown, the first slide block 6 is connected to the first base plate 7 through four mounting holes, three of which are elongated holes and the remaining one is a round hole. The first base plate 7 also has screw holes for fixing the first driver 24. The second angle adjusting block 4 is fixed to the first slide block 6, and it has two holes for fixing the first base plate 7, one of which is a machine hole and the other is an elongated hole. The inner side of the first base plate 7 has a boss. Two flat-head bolts pass through the elongated mounting holes and protrude from the back of the first slide block 6, and are finally fixed with nuts.

[0078] To adjust the vertical angle of the first driver 24, loosen the screws on the mounting hole (unlock the fixed state), and turn the screws corresponding to the elongated hole and the machine screws corresponding to the machine hole on the second angle adjustment block 4. The first base plate 7 can then rotate around the center of the round hole, thereby achieving vertical angle adjustment.

[0079] To adjust horizontally or left-right, simply loosen the nut on the flat-head bolt on the back of the first slide block 6. The first base plate 7 can then rotate horizontally with the boss position as the fulcrum, thus achieving horizontal or left-right adjustment. After adjusting to the appropriate vertical position, tighten the bolts and nut screws on the second angle adjusting block 4.

[0080] After adjusting to the appropriate left and right angles, tighten the mounting screws of the two elongated holes on the second angle adjustment block 4 (these two holes are used to fix the first angle adjustment block 29 to the first slide block 6), and tighten the nuts on the flat head bolts to fix the left and right positions of the first driver 24.

[0081] Optionally, to achieve visual adjustment of the relative positions of the first driver 24 and the second driver 23, the linear motion unit includes a first mounting block 8, a third counter, a third fixed base 9, and a second adjusting block 44. One side of the first mounting block 8 is fixed to the first slide 6, and the side of the first mounting block 8 away from the first slide 6 is fixedly connected to the first adjusting dovetail 12. The third fixed base 9 is fixed to the counter mounting side of the first mounting block 8, and the counter mounting side is perpendicular to the first slide 6. The third counter is fixed on the side of the third fixed base 9 away from the first mounting block 8. The second adjusting block 44 is disposed on the side of the first mounting block 8 away from the third fixed base 9, and one end of the second adjusting block 44 is connected to the second slide 14. The third counter includes a third adjusting shaft 11 for counting. The third fixed base 9 is threadedly connected to the third adjusting shaft 11, and one end of the third adjusting shaft 11 passes through the third fixed base 9 and the first mounting block 8 and is threadedly connected to the second adjusting block 44.

[0082] Optionally, a limiting block 13 can be provided at the bottom of the first mounting block 8. The limiting block 13 moves with the first mounting block 8, and the limiting block 13 has screws and mortise screws to adjust the angle of the first mounting block 8 relative to the slide unit, thereby adjusting the pitch angle of the second driver 23.

[0083] In one embodiment, the structure of the linear motion unit is as follows: Figure 9 , Figure 10As shown, the third fixing seat 9 can be a bearing housing. The third fixing seat 9 is fixed to the first mounting block 8. The third fixing seat 9 has two bearing mounting positions on the side near the first mounting block 8, where two thrust ball bearings 53 are installed. The external thread of the third adjusting shaft 11 corresponds to the two round nuts 54, and the third adjusting shaft 11 has a ring structure for pressing against the thrust ball bearings 53. The thread of the third adjusting shaft 11 is screwed into the two round nuts 54 to fix the two thrust ball bearings 53 and tighten the thread clearance. The external thread of the third adjusting shaft 11 corresponds to the internal thread of the second adjusting block 44. The thread of the third adjusting shaft 11 passes through the first mounting block 8 and is screwed into the second adjusting block 44. The third counting shaft 55 and the third adjusting shaft 11 are fixed together by screws. Because the third adjusting shaft 11 is axially fixed, it can only rotate, so the third housing 10 cannot move axially. The third counting shaft 55 can rotate synchronously with the third adjusting shaft 11. A boss on the third housing 10 extends into the third fixed seat 9, preventing the third housing 10 from rotating. The rotation of the third counting shaft 55 will change the reading of the third housing 10. When the third adjusting shaft 11 is rotated, the third adjusting shaft 11 and the third counting shaft 55 rotate synchronously, eventually changing the reading on the third housing 10. The second adjusting block 44 can move linearly back and forth under the interaction of the threads.

[0084] A first adjusting dovetail 12 is mounted on the first mounting block 8, allowing the second slide 14 to slide horizontally along the first adjusting dovetail 12. The second slide 14 is fixed to the second base plate 15. To adjust the front-to-back position of the second driver 23, the third adjusting shaft 11 is turned, causing the second slide 14 and the second base plate 15 to slide horizontally, thus visually adjusting the front-to-back position of the second driver 23 relative to the first driver 24. During operation, the rotation of the third adjusting shaft 11 can be used to adjust the milling cutters connected to the first driver 24 and the second driver 23 to be on the same horizontal plane.

[0085] Optionally, the plate pre-milling mechanism further includes a first moving module with a mounting plate 21, a slide rail seat 22, a second slide rail 50, and a second slider 51. One side of the mounting plate 21 is fixed to the base unit away from the slide groove unit. The slide rail seat 22 is fixed to the mounting plate 21 away from the base unit. The second slide rail 50 is fixed to the slide rail seat 22 away from the mounting plate 21. The second slider 51 is slidably nested on the second slide rail 50. The horizontal milling module is fixedly connected to the second slider 51. The top of the slide rail seat 22 is provided with a first angle adjustment block 29. The first angle adjustment block 29 contacts the top surface of the mounting plate 21 through a nut screw. The side of the slide rail seat 22 facing the mounting plate 21 is provided with a plurality of mounting screw holes for fixing the mounting plate 21. At least one of the mounting screw holes is an elongated hole.

[0086] Optionally, there may be two second slide rails 50, which are arranged side by side on the slide rail seat 22.

[0087] Optionally, the plate pre-milling mechanism further includes a second moving module equipped with a third drive unit, a third slide 31, a fourth counter, and a third adjusting block 34. The horizontal milling module is fixed to the third slide 31, and the third slide 31 is fixedly connected to the second slider 51. The third drive unit is fixed to the side of the slide rail 22, and the output end of the third drive unit is fixedly connected to the third slide 31. The fourth counter is fixed to the side of the third slide 31 away from the slide rail 22. The third adjusting block 34 and the second slide rail 50 are fixed to the same side of the slide rail 22. One end of the third adjusting block 34 passes through the opening on the third slide 31 and is opposite to the fourth adjusting shaft 30 of the fourth counter.

[0088] In one embodiment, one side of the mounting plate 21 is fixedly connected to the base unit of the milling cutter base 5, and the other side is fixedly connected to the slide rail base 22. The second slide rail 50 is fixed to the right side of the slide rail base 22; the second slider 51 is fixed to the second slide block 14. In addition to enabling the slide rail base 22 to slide relative to the second slide block 14, the second slider 51 and the second slide rail 50 also serve as a connector, allowing the slide rail base 22 to drive the right side part to rotate.

[0089] The mounting plate 21 has five central holes for connecting to the milling cutter base 5, and two other holes for fixing to the slide rail base 22. The slide rail base 22 has elongated holes and round holes. The first angle adjustment block 29 is fixed to the slide rail base 22; the first angle adjustment block 29 has elongated holes and a machine hole.

[0090] When adjusting the angle of the first drive motor 38, the slide rail 22 has an elongated hole, allowing it to rotate at a certain angle relative to the mounting plate 21. First, loosen the screws corresponding to the elongated hole and the round hole used to fix the mounting plate 21. Then, adjust the screws corresponding to the screw holes; the screw holes will then press against the inclined surface of the mounting plate 21, creating a certain angle between the slide rail 22 and the mounting plate 21. Finally, tighten the screws corresponding to the elongated hole and the round hole to complete the angle adjustment of the slide rail 22. The angle of the first drive motor 38 is adjusted in this way.

[0091] Specifically, the third drive unit may include a third drive cylinder 25, a third cylinder fixing block 26, and a third cylinder adjusting block 27. The third drive cylinder 25 is fixed on the slide rail seat 22 by the third cylinder fixing block 26. The third cylinder adjusting block 27 is fixed on the third slide seat 31 and connected to the cylinder shaft of the fourth drive cylinder. The extension and retraction of the cylinder shaft can make the third slide seat 31 slide along the direction of the second slide rail 50 (slide back and forth along the second slide rail 50 to realize the forward and backward operation), thereby pneumatically controlling the first driver 24 to perform the forward and backward operation.

[0092] like Figure 3As shown, the fourth fixed seat 33 is fixed on the third slide 31. The fourth fixed seat 33 and the second fixed pad 61 are fixed together with screws, restricting the axial movement of the second adjusting sleeve 62 between them. The hole on the second adjusting sleeve 62 corresponds to the elongated hole of the fourth adjusting shaft 30. The hole of the second adjusting sleeve 62 and the elongated hole of the fourth adjusting shaft 30 are connected by a pin, so that the two can rotate synchronously and the fourth adjusting shaft 30 can move axially relative to the second adjusting sleeve 62. The external thread on the fourth adjusting shaft 30 corresponds to the internal thread of the fourth fixed seat 33 and the second locking pad 63. The fourth adjusting shaft 30 is screwed into the fourth fixed seat 33 and the second locking pad 63, and the thread gap is tightened by tightening the screws fixed on the second locking pad 63. The fourth counting shaft 60 is fixed to the second adjusting sleeve 62 by screws, preventing the fourth housing 32 from moving axially. The fourth counting shaft 60 can rotate synchronously with the second adjusting sleeve 62. A boss on the fourth housing 32 extends into the fourth fixed seat 33, preventing the fourth housing 32 from rotating. Rotation of the fourth counting shaft 60 will change the reading of the fourth housing 32. When the fourth adjusting shaft 30 is rotated, the fourth adjusting shaft 30, the second adjusting sleeve 62, and the fourth counting shaft 60 rotate synchronously, ultimately changing the reading of the fourth housing 32.

[0093] To adjust the forward and reverse stroke of the first drive motor 38: the third adjusting block 34, located between the second slide rails 50, is fixed to the third slide block 31 and passes through the opening on the side of the third slide block 31; the fourth adjusting shaft 30 will press against the third adjusting block 34 and stop moving when the cylinder shaft of the fourth drive cylinder extends. Decreasing the extension of the fourth adjusting shaft 30 increases the stroke of the cylinder shaft, thus increasing the forward and reverse stroke of the first drive 24, and moving the first drive motor 38 forward a corresponding distance; increasing the extension of the fourth adjusting shaft 30 shortens the stroke of the cylinder shaft, thus shortening the forward and reverse stroke of the first drive motor 38. This allows for visual adjustment of the feed rate of the horizontal milling cutter 47.

[0094] Optionally, the second moving module further includes a lifting unit with a lead screw fixing seat 36, a second adjusting dovetail 40, and a fourth adjusting block 35. The third slide block 31 has a third slide groove on the side near the horizontal milling module. The second adjusting dovetail 40 is embedded in the third slide groove, and the side of the second adjusting dovetail 40 away from the third slide block 31 is connected to the horizontal milling module. The lead screw fixing seat 36 is fixed on the side of the third slide block 31 away from the second adjusting dovetail 40. The lead screw fixing seat 36 includes an adjusting lead screw 37 for rotational lifting. The fourth adjusting block 35 is fixed on the side of the second adjusting dovetail 40 near the third slide block 31. The end of the fourth adjusting block 35 away from the second adjusting dovetail 40 passes through the opening on the third slide block 31 and is opposite to the adjusting lead screw 37. The fourth adjusting block 35 is located within the stroke of the adjusting lead screw 37 for rotational lifting.

[0095] In one embodiment, the lead screw fixing seat 36 is mounted on the third slide 31. The horizontal milling module includes a driver base plate 39, a first drive motor 38 is fixed on the driver base plate 39, a second adjusting dovetail 40 is mounted on one side of the driver base plate 39, and a fourth adjusting block 35 is mounted on the second adjusting dovetail 40 and passes through an opening on the right slide. The adjusting lead screw 37 is fixed to the lead screw fixing seat 36 by a bearing and can rotate freely. The threaded end of the adjusting lead screw 37 is connected to the internal thread of the fourth adjusting block 35. To adjust the vertical position of the first drive motor 38: turn the adjusting lead screw 37, the fourth adjusting block 35 can move vertically up and down, causing the second adjusting dovetail 40 to slide along the dovetail groove structure formed by the third slide, thereby adjusting the vertical position of the first drive motor 38.

[0096] The sheet metal pre-milling mechanism will be further explained below based on its workflow.

[0097] In one embodiment, such as Figure 18 , Figure 19 As shown, vertical saw blade cutters (i.e., first vertical cutter 45 and second vertical cutter 46) are mounted on the first driver 24 and the second driver 23, and a horizontal cutter 47 is mounted on the first drive motor 38.

[0098] First, adjust the angle of the first driver 24, adjust the angle and forward / backward position of the second driver 23, and adjust the angle of the first drive motor 38. After adjustment, the first vertical milling cutter 45 and the second vertical milling cutter 46 are on the same plane, and the axis of the horizontal milling cutter 47 is exactly perpendicular to this plane.

[0099] Next, adjust the vertical position of the first drive motor 38, and adjust the overall vertical position of the first driver 24 and the second driver 23. After adjustment, the horizontal milling cutter 47 can mill the upper and lower surfaces of the plate, and the upper and lower edges of the first vertical milling cutter 45 and the second vertical milling cutter 46 both exceed the center line of the plate.

[0100] Finally, based on the preset milling amount of the sheet metal, the overall forward and backward stroke is adjusted, and the forward and backward stroke of the first drive motor 38 is also adjusted.

[0101] Specific working modes include:

[0102] Work Mode 1:

[0103] In one embodiment, the plate milling depth is 5mm. The horizontal milling cutter 47, located at the front end of the plate pre-milling mechanism, first mills the plate to a depth of 1-2mm. Then, the second vertical milling cutter 46 and the first vertical milling cutter 45 jointly mill the remaining portion of the plate to achieve the required milling depth. During milling, referring to the initial reading of the first counter, the length of the first adjusting shaft 19 is shortened by 5mm, increasing the overall stroke of the pre-milling mechanism by 5mm; referring to the initial reading of the fourth counter, the length of the fourth adjusting shaft 30 is shortened by 2mm, increasing the stroke of the first drive motor 38 by 2mm. At this time, the edge of the horizontal milling cutter 47 is 3mm lower than the plane corresponding to the second vertical milling cutter 46 and the first vertical milling cutter 45. During operation, the horizontal milling cutter 47 mills a maximum depth of 2mm, with the remaining 3mm milling depth completed jointly by the second vertical milling cutter 46 and the first vertical milling cutter 45.

[0104] The dynamic process is as follows: When the pre-milling mechanism is working: the shaft of the first drive cylinder 16 extends, pushing the milling cutter base 5 to the end position of its stroke (the machining position of the horizontal milling cutter 47); the shaft of the third drive cylinder 25 extends, pushing the third slide 31 to the end position of its stroke. The horizontal milling cutter 47 first mills a small depth of the sheet metal, and then the second vertical milling cutter 46 and the first vertical milling cutter 45 jointly mill the remaining depth. Specifically, the second vertical milling cutter 46 is responsible for milling the lower half of the remaining depth, and the first vertical milling cutter 45 is responsible for milling the upper half of the remaining depth. This achieves the effect of milling the sheet metal to the preset cutting depth.

[0105] Working Mode Two:

[0106] The plate needs to be milled to a depth of 5mm. Adjust the positions of the first drive motor 38, the first driver 24, and the second driver 23 so that the edge of the horizontal milling cutter 47 is in the same position as the planes corresponding to the first vertical milling cutter 45 and the second vertical milling cutter 46. Adjust the stroke (i.e., feed rate) of the pre-milling mechanism according to the initial reading of the first counter so that its stroke reaches the predetermined milling depth (i.e., 5mm depth).

[0107] The dynamic process is as follows: the shaft of the first drive cylinder 16 extends, pushing the milling cutter base 5 to the end of its stroke; the shaft of the third drive cylinder 25 extends, pushing the third slide 31 to the end of its stroke. The horizontal milling cutter 47 rotates counterclockwise, milling off 5mm of the front end of the sheet metal to prevent edge chipping; after milling to a set distance (usually 50mm), the shaft of the third drive cylinder 25 retracts, at which point the third slide 31 returns to its initial position. The remaining milling is completed by the first vertical milling cutter 45 and the second vertical milling cutter 46. The first vertical milling cutter 45 rotates counterclockwise, and the second vertical milling cutter 46 rotates clockwise, with the cutting edges rotating inwards towards the sheet metal to prevent edge chipping. Specifically, the second vertical milling cutter 46 is responsible for milling the lower half of the remaining depth, and the first vertical milling cutter 45 is responsible for milling the upper half of the remaining depth. This achieves the effect of pre-milling the sheet metal to a preset cutting depth (this method is more effective when the sheet metal quality is not very good).

[0108] Finally, the shaft of the first drive cylinder 16 retracts, and the milling cutter base 5 moves back. This results in a flat edge banding surface for the sheet metal.

[0109] The sheet metal pre-milling mechanism of this application embodiment includes a horizontal milling module equipped with a horizontal milling cutter and a vertical milling module equipped with a first vertical milling cutter and a second vertical milling cutter. The horizontal milling module and the vertical milling module are used to mill the same edge sealing surface of the sheet metal. The vertical milling module is located on the sheet metal departure side of the horizontal milling module. During milling, the first vertical milling cutter is located above the edge sealing surface, and the second vertical milling cutter is located below the edge sealing surface. The horizontal milling cutter is located on the same horizontal plane as the sheet metal and on the side of the edge sealing surface away from the sheet metal. This application embodiment can use the horizontal milling cutter and two vertical milling cutters to mill the sheet metal sequentially, effectively increasing the milling amount of the pre-milling mechanism, enabling the pre-milling mechanism to adapt to large milling amount working scenarios, thereby effectively reducing milling cutter wear, increasing milling cutter service life, reducing production costs, and improving pre-milling effect and edge sealing efficiency, while reducing the defect rate.
