The machine includes a worktable and a milling cutter on it, with a splash guard movably connected to the worktable. Inside the splash guard is a partition plate with a connecting opening, dividing it into a negative pressure chip collection area and a feed area. The feed area has a feed wheel. A protective plate is installed on the partition plate above the feed wheel, protecting its upper and side surfaces and forming a chip collection channel with the top wall of the feed area.

Description

Technical Field

[0001] The embodiments of the present invention relate to the field of vertical milling machine technology, and more specifically, to a vertical milling machine with a dust removal function. Background Technology

[0002] A vertical milling machine is a processing equipment used for processing sheet materials (such as plastic sheets, gypsum boards, and wood boards). It mainly uses a high-speed rotating milling cutter to perform milling, grooving, and shaping operations on the sheet material.

[0003] Specifically, first select a suitable milling cutter according to the processing requirements (such as grooving, edge milling, and shaping), and install it on the vertical spindle. Then, install guide plates on both sides of the milling cutter along the direction of the material's travel, so that the outer edge of the milling cutter protrudes from the gap between the two guide plates. Then, start the processing. The vertical spindle drives the milling cutter to rotate at high speed. At the same time, place the material to be processed flat on the worktable and close to the guide plates. Push the material so that it passes through the gap between the two guide plates, contacts the rotating milling cutter, and cuts the material to form the required shape, thus completing the processing.

[0004] The action of pushing the sheet metal is usually accomplished by the active feed wheel located inside the splash guard above the sheet metal and the worker. When processing the sheet metal, a large amount of debris is generated at the milling cutter. Due to the high-speed rotation of the milling cutter, the debris is thrown in all directions. Some of the debris can be drawn away by the negative pressure fan next to the milling cutter, but some debris still flies into the splash guard and remains on the active feed wheel. If this debris is not dealt with in time, the active feed wheel may damage the sheet metal in the long run, and at the same time affect the processing accuracy. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a vertical milling machine with a dust removal function, which solves the technical problem in the related art that during the processing of sheet metal by a vertical milling machine, some of the debris that splashes into the splash guard may remain on the active feed wheel therein, causing damage to the sheet metal and affecting the processing accuracy.

[0006] According to one aspect, at least one embodiment of the present invention provides a vertical milling machine with a dust removal function, comprising:

[0007] The worktable has a milling cutter for machining sheet metal that is rotatably mounted on its top surface.

[0008] The splash guard is movably connected to the worktable. The inner wall of the splash guard is equipped with a partition plate with a connecting port, which can divide the interior of the splash guard into a negative pressure chip collection area and a feed area. The inner wall of the feed area is equipped with a feed wheel, which is located on the side of the milling cutter and is used to contact the top surface of the plate to drive the plate to move horizontally.

[0009] The guard plate is installed on the partition plate and located above the feed wheel. The guard plate is used to protect the top and sides of the feed wheel, and a chip collection channel is formed between the guard plate and the top wall of the feed area. The chip collection channel is connected to the negative pressure chip collection area through the connecting port so as to absorb the debris in the splash guard to the negative pressure chip collection area.

[0010] For example, in a vertical milling machine with dust removal function provided in at least one embodiment of the present invention, a chip collection hopper for collecting chips is detachably provided in the negative pressure chip collection area, and the negative pressure chip collection area is also connected to a negative pressure pipeline, and a filter screen is provided in the port of the negative pressure pipeline.

[0011] For example, in a vertical milling machine with dust removal function provided in at least one embodiment of the present invention, the negative pressure chip collection area has openings at both ends, and each opening is detachably provided with an end plate. The two sides of the chip collection bucket are respectively slidably connected to the inner wall of the splash guard and the partition plate. The chip collection bucket, the splash guard, the partition plate and the two end plates together form a closed negative pressure chip collection area.

[0012] For example, in a vertical milling machine with dust removal function provided in at least one embodiment of the present invention, the shaft of the feed wheel is arranged horizontally, there are several feed wheels, and the several feed wheels are arranged at intervals along the moving direction of the plate, and it further includes:

[0013] The motor is detachably mounted on one of the end plates and is used to drive the feed wheel at the end to rotate.

[0014] Synchronous toothed belts are fitted onto the pulleys of several feed wheels to drive the feed wheels to rotate synchronously.

[0015] For example, in a vertical milling machine with dust removal function provided in at least one embodiment of the present invention, two guide plates are detachably provided on the top surface of the worktable along the moving direction of the plate. Both guide plates are located between the milling cutter and the splash guard. Each guide plate has a guide surface on the side near the splash guard. The guide surface is used to provide guidance and limiting function for the plate. A cutting gap is formed between the two guide plates. The outer edge of the milling cutter passes through the cutting gap so as to be able to cut the moving plate.

[0016] For example, in a vertical milling machine with dust removal function provided in at least one embodiment of the present invention, a lateral pressure wheel is rotatably provided on the inner wall of the feed zone. The shaft of the lateral pressure wheel is arranged horizontally. The lateral pressure wheel is located between two adjacent feed wheels or on the extension path of the arrangement direction of several feed wheels. A synchronous toothed belt is sleeved on the pulleys of several feed wheels and the pulley of the lateral pressure wheel, and meshes with the pulleys of each feed wheel and the lateral pressure wheel, so that several feed wheels and the lateral pressure wheel can rotate synchronously.

[0017] The outer peripheral wall of the lateral pressure roller is provided with a threaded part. After the lateral pressure roller rotates, the threaded part can apply a force to the plate that is tightly attached to the guide surface during the movement of the plate.

[0018] For example, in a vertical milling machine with dust removal function provided in at least one embodiment of the present invention, a chip collection channel is provided on the top surface of the worktable, and a cross-shaped limiting strip is rotatably provided in the chip collection channel. The center position of the cross-shaped limiting strip has four limiting slots, two of which are coplanar with the top surface of the worktable, and the rotation axis of the cross-shaped limiting strip is set along the moving direction of the plate.

[0019] The guide plate is detachably installed at the edge of the chip collection channel, and the guide surface is set vertically and located directly above the limiting seam near the splash guard, so that the limiting seam and the guide surface together provide guiding and limiting functions for the plate. After the cross limiting strip is rotated, other limiting seams can be switched to cooperate with the guide surface.

[0020] For example, in a vertical milling machine with dust removal function provided in at least one embodiment of the present invention, a limiting column is also movably provided on the side of the worktable. The moving direction of the limiting column is perpendicular to the moving direction of the plate. After the limiting column moves, it can apply a force to the plate that is tightly attached to the guide surface during the moving process of the plate.

[0021] For example, in a vertical milling machine with dust removal function provided in at least one embodiment of the present invention, a chip suction block is provided on the top surface of the worktable, the chip suction block has a chip suction cavity, the milling cutter is located in the chip suction cavity, and the chip suction cavity is connected to a negative pressure pipe.

[0022] For example, in a vertical milling machine with dust removal function provided in at least one embodiment of the present invention, a multi-axis movable frame is provided on the top surface of the worktable, the multi-axis movable frame has a movable end, and a splash guard is detachably provided on the movable end.

[0023] The beneficial effects of the embodiments of the present invention are as follows:

[0024] This invention addresses the problem of debris residue on the active feed wheel by optimizing the internal structure of the splash guard. First, a partition plate is installed on the inner wall of the splash guard, dividing its interior into a negative pressure chip collection zone and a feed zone. This places the feed wheel in an independent feed zone, creating an additional space to provide the necessary negative pressure for absorbing debris splashed into the feed zone. The connecting port of the partition plate connects the two zones, ensuring proper functioning. Second, a protective plate is installed above the feed wheel. This plate protects the top and sides of the feed wheel, preventing debris from directly contacting it. Furthermore, the protective plate forms a chip collection channel with the top wall of the feed zone. This channel connects to the negative pressure chip collection zone through a connecting port, further enhancing the absorption of debris around the feed wheel by extending the strong negative pressure at the negative pressure port closer to the feed wheel. This prevents the strong negative pressure at the connecting port from being insufficient to completely handle the debris.

[0025] When chips generated by the milling cutter splash into the splash guard, some chips are blocked by the guard plate, preventing them from falling directly onto the feed wheel. Simultaneously, the negative pressure generated in the negative pressure chip collection zone acts on the feed zone through the connecting port and chip collection channel, promptly drawing in chips that splash into the feed zone and then guiding them into the negative pressure chip collection zone for collection. This significantly reduces the amount of chips remaining on the active feed wheel, effectively preventing material damage caused by chip residue and ensuring machining accuracy.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0039] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0040] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0043] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] like Figures 1-4 As shown, a vertical milling machine with dust removal function is illustrated in one embodiment of the present invention. This vertical milling machine with dust removal function is mainly used in the processing of plastic boards, gypsum boards, wood boards and other board materials 2. When performing precision milling, grooving, forming and other processing operations on the board material 2, the machine achieves efficient processing and debris removal by means of the coordinated operation of various components (feed wheel 6 and guide plate 14, etc.), ensuring processing quality and equipment stability. The moving direction of the board material 2 is defined as horizontal transverse, and the moving direction of the limiting column 18 is defined as horizontal longitudinal.

[0045] The worktable 1 provides a basic bearing surface for processing the sheet metal 2, and a milling cutter 3 is rotatably mounted on its top surface. The milling cutter 3, as the core component for cutting, is driven by a vertical shaft on the top surface of the worktable 1. Before processing, a suitable milling cutter 3 is assembled onto the vertical shaft, and then the vertical shaft is driven by a motor to rotate at high speed to complete milling operations. The guide plate 14, as a guiding component during the processing, is also very important to ensure the processing accuracy of the sheet metal 2. Specifically, as shown... Figure 1 , Figure 8 , Figure 9As shown, the guide plate 14, which extends horizontally, is positioned on the top surface of the worktable 1 by a general fixture. This allows the vertical side surface (guide surface 1401) to provide stable guidance and limiting for the horizontal movement of the plate 2 supported on the top surface of the worktable 1. The general fixture is detachable for quick maintenance. At the same time, there are two guide plates 14 to ensure that the outer edge of the milling cutter 3 can protrude through the cutting gap 15 between the two guide plates 14. This allows the outer edge of the milling cutter 3, which protrudes through the cutting gap 15, to cut the plate 2 when it moves horizontally along the guide surface 1401, thus completing the operation of the vertical milling machine.

[0046] Furthermore, the splash guard 4 is movably connected to the worktable 1, and its position can be flexibly adjusted to adapt to processing requirements. The partition plate 5, which is integrally formed vertically along its inner wall, divides the internal space of the splash guard 4 into a negative pressure chip collection area 401 and a feed area 402, and connects the two areas through the opening 501. The feed wheel 6 (the shaft of the feed wheel 6 is set along the horizontal longitudinal direction) is rotatably installed on the inner wall of the feed area 402 (i.e. on the partition plate 5). The feed wheel 6 is located on the side of the guide surface 1401 away from the milling cutter 3, and is responsible for stabilizing the extrusion of the plate 2 on the top surface of the worktable 1, and rotating to drive the plate 2 to move horizontally, and cooperate with the milling cutter 3 to complete the processing feed action.

[0047] For the movable connection structure of the splash guard 4, a hinge structure or a pivot hinge structure can be used. For the hinge type: a hinge is installed at the position corresponding to one edge of the splash guard 4 and the worktable 1. The two leaves of the hinge are fixed to the splash guard 4 and the worktable 1 respectively, so that the splash guard 4 can rotate around the hinge axis to realize the opening and closing action. During processing, the splash guard 4 is rotated to cover the processing area. When maintenance or cleaning is required, the splash guard 4 is rotated to open, which facilitates the inspection and maintenance of internal components such as the feed wheel 6 and the milling cutter 3, as well as the cleaning of residual debris in the negative pressure chip collection area 401. For the pivot hinge type: a pivot seat is set on the worktable 1, and a pivot is installed at the bottom of the splash guard 4. The pivot is inserted into the pivot seat, and the splash guard 4 can rotate around the pivot to adjust the angle and position. For example, when processing plates 2 of different thicknesses, the splash guard 4 can be rotated to adapt to the height of the plate 2. At the same time, when not processing, the splash guard 4 can be rotated to the side for easy maintenance of the overall equipment.

[0048] Preferred, such as Figure 1 , Figure 2As shown, the top edge of the workbench 1 is bolted or welded with a multi-axis movable frame 21. Through multi-axis linkage, it provides the splash guard 4 with flexible spatial position adjustment capability to meet the needs of different processing scenarios and the adaptation of the sheet metal 2. Specifically, the movable end 2101 is composed of a cantilever beam and a multi-joint axis (similar to a robotic arm), which can realize the "hovering + multi-angle rotation" of the splash guard 4 within a certain radius. The movable end 2101 and the splash guard 4 can be quickly connected by buckles or bolts to balance the convenience of disassembly and processing stability. For example, with bolt connection, the top surface of the splash guard 4 has a matching flange surface at the corresponding position. The bolts are inserted into the flange holes for fastening, resulting in high connection strength and good stability. This is suitable for processing scenarios with large vibrations, such as high-speed milling, to ensure that the splash guard 4 does not shift.

[0049] Furthermore, to prevent the feed wheel 6 from being affected by debris, a guard plate 7 is integrally formed above the feed wheel 6 on the partition plate 5, such as... Figures 2-4 As shown, specifically, the semi-enclosed feed wheel 6 is integrally formed on one side of the partition plate 5, and the other side extends outward from the splash guard 4 and bends towards the side of the feed wheel 6 to protect the top and side of the feed wheel 6. At the same time, both ends of the guard plate 7 bend and extend towards the inner top wall of the feed area 402, forming a chip collection channel 8 together with the top wall. This channel is connected to the negative pressure chip collection area 401 through the connecting port 501. On the one hand, the guard plate 7 plays the role of physically intercepting debris. On the other hand, it makes full use of the remaining gaps to form the chip collection channel 8, allowing the negative pressure of the negative pressure chip collection area 401 to extend to the periphery of the feed wheel 6. The debris that splashes onto the feed area 402 will be absorbed by the negative pressure in the channel and guided into the negative pressure area through the connecting port 501. The strong negative pressure at the connecting port 501 is extended to the vicinity of the feed wheel 6, improving the absorption effect.

[0050] Regarding the negative pressure function of the negative pressure chip collection area 401, common forms include negative pressure fan + pipeline or centrifugal negative pressure mechanism; for example, negative pressure fan + pipeline, where a negative pressure fan is installed outside the equipment, and negative pressure is supplied through negative pressure pipeline 10 (e.g. Figure 1 (As shown) is connected to the negative pressure chip collection area 401, and a filter screen is provided in the port of the negative pressure pipeline 10. When the fan is running, the air inside the negative pressure chip collection area 401 is drawn out, so that the negative pressure chip collection area 401 forms a negative pressure, which absorbs the debris flowing to the negative pressure chip collection area 401. The filter screen further blocks the debris from flowing along the negative pressure pipeline 10 so that all the debris is collected in it.

[0051] Furthermore, to facilitate the rapid discharge and centralized treatment of collected debris and avoid secondary pollution, a cyclone separator can be installed between the negative pressure debris collection area 401 and the power source (such as a negative pressure fan). The debris-laden airflow enters the separator and rotates at high speed along the cylinder wall. Due to centrifugal force, the debris is thrown against the cylinder wall and slides into the dust collection bin. The purified air is then discharged through the fan. This efficient separation of debris reduces wear caused by debris entering the power source and extends the lifespan of the negative pressure system. Preferably, a removable debris collection hopper 9 (drawer-type dust collection box) is used within the negative pressure debris collection area 401. Figure 5 , Figure 6 As shown, the negative pressure chip collection area 401 has openings 403 at both ends, and an end plate 11 is bolted to each opening 403. The chip collection hopper 9 is slidably connected to the inner wall of the splash guard 4 and the slide rail of the partition plate 5 by sliders on both sides. After the chip collection hopper 9 is connected, the chip collection hopper 9, the splash guard 4, the partition plate 5 and the two end plates 11 can jointly form a closed negative pressure chip collection area 401. After the airflow carries the debris into the chip collection area, the debris is slowed down by gravity or airflow and falls into the dust collection box. The end plates 11 can be disassembled periodically and the chip collection hopper 9 can be pulled out for cleaning. The operation is convenient and more suitable for the collection of a small amount of debris in this scenario.

[0052] Working process: During processing, the milling cutter 3 rotates at high speed to process the plate 2, generating chips. A small portion of the chips splash into the splash guard 4. Due to the negative pressure chip collection area 401 divided by the partition plate 5, negative pressure can be generated. The chip collection channel 8 is connected to the negative pressure chip collection area 401 through the connecting port 501. Under the action of negative pressure, the chips that splash into the splash guard 4 are adsorbed by the strong negative pressure and enter the negative pressure chip collection area 401 through the chip collection channel 8 and the connecting port 501. At the same time, the feed wheel 6 rotates and drives the plate 2 to move continuously, so that the plate 2 can be processed by the milling cutter 3 segment by segment to complete the predetermined shape processing. Under the protection of the guard plate 7, the chips are reduced from directly remaining on the feed wheel 6, ensuring that the feed wheel 6 feeds the plate 2 stably and accurately, and preventing the plate 2 from being crushed.

[0053] This vertical milling machine with dust removal function uses a partition plate 5, a guard plate 7, and a chip collection channel 8 in conjunction with a negative pressure chip collection design to extend strong negative pressure to near the feed wheel 6. This effectively collects small pieces of debris that splash into the splash guard 4, preventing debris residue from damaging the sheet metal 2 and affecting machining accuracy. This improves machining quality and equipment reliability. The overall structure is also simple, making the vertical milling machine machining process more stable and efficient. In contrast, the traditional vertical milling machine splash guard 4 only provides simple physical protection for the feed wheel 6 and cannot specifically and efficiently collect and guide debris that splashes into the interior, thus failing to effectively prevent debris residue from remaining on the feed wheel 6.

[0054] As a further implementation, the drive structure of the feed wheel 6 utilizes the motor 12 and the synchronous toothed belt 13 to achieve synchronous operation, specifically as follows: Figure 5 , Figure 7As shown, there are several feed wheels 6, which are arranged horizontally at intervals and rotatably mounted on the partition plate 5. The motor 12 is bolted to one of the end plates 11 and connected to the shaft of the feed wheel 6 at the end. The partition plate 5 provides a certain support function, and the synchronous toothed belt 13 is sleeved on the pulleys of several feed wheels 6 and meshes with each pulley of the feed wheel 6 so that the motor 12 can drive several feed wheels 6 to rotate synchronously. In the traditional case, the motor 12 is usually located at the top of the splash guard 4, and the transmission structure extends from top to bottom into the splash guard 4 and connects with the feed wheels 6 therein. However, in this invention, the guard plate 7 is arranged above the feed wheels 6, occupying the position of the transmission structure. Therefore, the position of the motor 12 is improved to be on the end plate 11 of the opening 403 at the end of the splash guard 4, and the drive starts from the feed wheel 6 at the end, thereby avoiding the position of the guard plate 7, making the structure more compact and improving the driving function.

[0055] As a further implementation method, such as Figures 5-7 As shown, the upgraded feed wheel 6 functions as a lateral pressure wheel 16, which can apply a force to the plate 2 in close contact with the guide surface 1401 to further improve processing accuracy and prevent the plate 2 from shaking. Specifically, the installation method and structure of the lateral pressure wheel 16 are basically the same as those of the feed wheel 6. It is located between two adjacent feed wheels 6 or on the extension path of the arrangement direction of several feed wheels 6 (i.e., it can function normally by applying pressure to the plate 2), and the synchronous toothed belt 13 is sleeved on the pulleys of several feed wheels 6 and the lateral pressure wheel 16. The pulley meshes with the pulleys of each feed wheel 6 and the lateral pressure wheel 16, so that several feed wheels 6 and lateral pressure wheels 16 can rotate synchronously. The only structural difference between the lateral pressure wheel 16 and the feed wheel 6 is that the outer peripheral wall of the lateral pressure wheel 16 is provided with a threaded part 1601, which enables the lateral pressure wheel 16 to rotate synchronously with the feed wheel 6, and the threaded part 1601 on it can apply a force to the plate 2 in close contact with the guide surface 1401 during the movement of the plate 2, so as to ensure the stability of the movement of the plate 2.

[0056] As a further implementation method, such as Figures 8-10As shown, after long-term processing of sheet metal 2 by the vertical milling machine, the gap formed between the guide plate 14 and the top surface of the worktable 1 may become clogged with small particles of debris, which are difficult to clean. This reduces the fit between sheet metal 2 and guide surface 1401, making sheet metal 2 prone to displacement and affecting processing accuracy. As a result, the guide plate 14 needs to be replaced. Replacing the guide plate 14 is a cumbersome process and requires high assembly precision. Therefore, a rotating cross-shaped limiting strip 17 is added. Simply put, by rotating, different vertical limiting slots 1701 at their center positions can be switched to fit with the guide surface 1401, providing stable guidance and limiting for sheet metal 2 from both horizontal and vertical perspectives. At the same time, when one of the limiting slots 1701 becomes clogged with debris, a new limiting slot 1701 can be quickly replaced without needing to replace the guide plate 14, thus improving the equipment's versatility and processing accuracy stability.

[0057] Specifically, within the chip collection channel 101 on the top surface of the workbench 1, the cross-shaped limiting strip 17 is rotatably arranged in a "cross" shape. It has a motor-driven rotating shaft (horizontally) at its center and four vertical limiting slots 1701. One side of the strip is exposed above the top surface of the workbench 1, so that two limiting slots 1701 are initially coplanar with the top surface of the workbench 1. After rotation, the other side will be exposed above the top surface of the workbench 1, so that the new limiting slot 1701 is coplanar with the top surface of the workbench 1, thus playing a normal guiding and limiting role. Correspondingly, to avoid interference with the guide rod, the guide plate 14 is mounted on the edge of the chip collection channel 101 by a clamp. Its bottom is provided with a semi-arc limiting arc surface adapted to the rotation of the cross-shaped limiting strip 17. At the same time, the limiting arc surface continues to extend upward, which is the guide surface 1401. The guide surface 1401 is located directly above the limiting slot 1701 on the side coplanar with the top surface of the workbench 1 and close to the splash guard 4.

[0058] During processing, the sheet 2 moves along the moving direction, with its side embedded in the limiting slot 1701, and simultaneously adhering to the guide surface 1401 of the guide plate 14. Under horizontal and vertical constraints, it stably passes through the processing area of ​​the milling cutter 3. When the limiting slot 1701 is blocked by debris, the cross limiting strip 17 is rotated to switch to another limiting slot 1701, so that the new limiting slot 1701 is connected to the area directly below the guide surface 1401 and recombined with the guide plate 14, providing guidance and limiting for the processing of the new sheet 2, and achieving rapid adaptation and adjustment.

[0059] Regarding the chip collection channel 101, such as Figure 10 As shown, there can be a separate descent channel, or a negative pressure fan can be added for recycling. I won't go into too much detail here, as long as it can collect debris.

[0060] As a further implementation method, such as Figure 8As shown, the side of the worktable 1 is also equipped with a limiting column 18 that moves horizontally and longitudinally. This can be achieved by a built-in servo motor or lead screw, etc., which will not be described in detail here. It has the same function as the side pressure roller 16, both of which apply a force to the plate 2 that is in close contact with the guide surface 1401. Before processing the plate 2 each time, the limiting column 18 can be moved precisely to fit the side of the plate 2 before processing, so as to prevent it from swaying left and right during the process.

[0061] As a further implementation method, such as Figure 8 As shown, a chip-collecting block 19 is installed around the milling cutter 3 on the top surface of the worktable 1 to collect most of the flying chips. It is also sucked up by the connected negative pressure pipe 20. Specifically, the chip-collecting block 19 has an arc-shaped chip-collecting cavity 1901. The milling cutter 3 is located in the chip-collecting cavity 1901. During the machining process, under the negative pressure of the negative pressure pipe 20, the chips that fly off the milling cutter 3 are directly exposed in the chip-collecting cavity 1901. The arc shape also allows the chips to be sucked away by the negative pressure pipe 20 more smoothly.

[0062] Overall working principle: Preparation: According to the processing requirements of the sheet metal 2, such as grooving, edge milling, or forming, select a suitable milling cutter 3 and install it on the vertical spindle. At the same time, install the vertically set guide plate 14 at the edge of the chip collection channel 101 on the top surface of the worktable 1, ensuring that its guide surface 1401 is directly above the limiting slot 1701 near the splash guard 4. In addition, install the multi-axis movable frame 21 on the top surface of the worktable 1, and install the splash guard 4 on the movable end 210 of the multi-axis movable frame 21. 1. The splash guard 4 is adjusted to a suitable position by the multi-axis movable frame 21. Inside the splash guard 4, the partition plate 5 has divided its interior into a negative pressure chip collection area 401 and a feed area 402. The feed wheel 6, which is rotatably mounted on the inner wall of the feed area 402, is also adjusted into position. The guard plate 7 is installed on the partition plate 5 and located above the feed wheel 6, forming a chip collection channel 8 with the inner top wall of the feed area 402. This channel is connected to the negative pressure chip collection area 401 through the connecting port 501 on the partition plate 5, ready to start processing.

[0063] Processing procedure: The equipment is turned on, and the vertical spindle drives the milling cutter 3 to rotate at high speed. The plate 2 to be processed is placed flat on the worktable 1. The side of the plate 2 is embedded in the limiting slot 1701 of the cross-shaped limiting strip 17, and simultaneously, the side is in close contact with the guide surface 1401 of the guide plate 14. Under the dual constraints of horizontal (limiting slot 1701) and vertical (guide plate 14), the plate 2 is precisely positioned. At this time, the active feed wheel 6 inside the splash guard 4 above the plate 2 rotates, cooperating with the worker to push, causing the plate 2 to move smoothly along the trajectory defined by the guide plate 14 and the limiting slot 1701 towards the milling cutter 3. During the cutting process of the milling cutter 3 on the plate 2, a large number of chips are generated and will fly around. Some chips are directly sucked away by the negative pressure fan next to the milling cutter 3. However, the chips that fly into the splash guard 4 are difficult to fall directly onto the feed wheel 6 due to the obstruction of the guard plate 7. At the same time, the chip collection channel 8 uses the negative pressure generated by the connection between the connecting port 501 and the negative pressure chip collection area 401 to absorb these chips that fly into the feed area 402 and let them enter the negative pressure chip collection area 401 through the connecting port 501. This effectively avoids chips remaining on the feed wheel 6 and ensures the stability and accuracy of the plate 2 processing.

[0064] Adjustment and maintenance: If the limiting slot 1701 is blocked by debris, rotate the cross limiting strip 17 to switch other limiting slots 1701 to cooperate with the guide surface 1401 to meet the guiding and limiting requirements of the new plate 2. If the position of the splash guard 4 needs to be adjusted, operate the multi-axis movable frame 21 to move the splash guard 4. After processing, regularly clean the debris collected in the negative pressure chip collection area 401 and check the wear of each part of the equipment to ensure that the equipment is always in good working condition and ready for the next processing.
