Description

Technical Field

[0001] This invention belongs to the field of gantry machining centers, specifically a CNC gantry machining center. Background Technology

[0002] With the development of my country's manufacturing industry, the application of CNC machine tools is becoming increasingly widespread, and gantry machining centers are becoming more and more common. Current CNC gantry machining centers are mainly composed of a bed, worktable, left and right columns, crossbeam, slide saddle, tool magazine, machine head, operating table, and electrical control box, which can complete multiple processes such as milling, drilling, reaming, and boring, and are suitable for roughing and finishing of large and medium-sized parts in various industries.

[0003] A patent application with publication number CN212762356U discloses a CNC gantry machining center, which includes a material conveying mechanism, a lathe, and columns symmetrically arranged on both sides of the lathe. Each column has a pneumatic drive mechanism at its top, and a horizontal movable block is provided between the two pneumatic drive mechanisms. Each pneumatic drive mechanism has a movable rod that can be connected to both sides of the movable block. A lifting drive mechanism is provided on the vertical surface of the movable block. The lifting drive mechanism includes a vertical moving plate that moves linearly in the vertical direction. A drive tool is mounted on the vertical surface of the vertical moving plate. The device moves the drive tool horizontally by using air pressure, which increases the movement speed of the drive tool during machining and improves machining efficiency.

[0004] In existing technologies, iron filings generated during processing inevitably fly everywhere. Some iron filings fall onto the lead screw that drives the machine head, causing the machine head to jam during processing, resulting in uneven operation and affecting the processing effect. It is also impossible to clean the lead screw in time, often requiring machine shutdown for maintenance. Furthermore, the lack of lubricating oil on the lead screw can easily cause the machine to jam, making horizontal movement unstable.

[0005] Therefore, the present invention provides a CNC gantry machining center. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: A CNC gantry machining center of the present invention includes a base plate, columns slidably connected to both sides of the upper end of the base plate, a sliding component provided at the upper end of the column, the sliding component being used to drive the tool head to slide, an irregularly shaped slider fixedly connected to one side of the column, a lead screw threadedly connected to the middle of the irregularly shaped slider, a clamping mechanism provided on both sides of the irregularly shaped slider, the clamping mechanism including clamping plates provided on both sides of the lead screw, an arc-shaped plate elastically connected to the inner side of the clamping plate, and a brush provided on the inner side of the arc-shaped plate.

[0008] Specifically, during use, the workpiece is placed on the base plate, and the sliding assembly drives the cutter head to move and process the workpiece. The drive screw rotates, causing the irregularly shaped slider to slide, which in turn causes the cutter head on the column to slide, facilitating processing of the workpiece over a wide range. During use, impurities may accumulate in the gaps of the screw, causing jamming, which requires regular cleaning. When the screw speed slows down and cleaning is needed, the clamping plates on both sides of the drive screw move closer to the screw, and the clamping plates drive the brushes on the arc plate to clean the screw.

[0009] Preferably, rectangular blocks are fixedly connected to the four corners of the base plate, a rectangular plate is fixedly connected between two rectangular blocks, an irregularly shaped block is fixedly connected to the upper end of the rectangular blocks, a lead screw is rotatably connected between the two irregularly shaped blocks, and a first motor for driving the lead screw to rotate is fixedly connected to one side of the rectangular blocks; the sliding assembly includes a first slide rail fixedly connected to the upper end of the column, a first slide table slidably connected to the first slide rail, a second slide rail fixedly connected to one side of the first slide table, a second slide table slidably connected to the second slide rail, and the lower end of the second slide table is fixedly connected to the cutter head.

[0010] Specifically, when processing the workpiece, the first motor is started to drive the lead screw to rotate. The lead screw drives the column to slide above the base plate through the irregularly shaped slider. The first slide rail is started to drive the first slide table to slide. The second slide rail is started to drive the second slide table to drive the cutter head to slide, so that the cutter head can move in multiple directions to process the workpiece, which can adapt to workpieces of different thicknesses.

[0011] Preferably, the clamping mechanism further includes a bidirectional lead screw threadedly connected to the clamping plate. The bidirectional lead screw is rotatably mounted on the side wall of the column via two fixing blocks. A second motor that drives the bidirectional lead screw to rotate is installed above one of the fixing blocks. The inner side of the clamping plate is fixedly connected to the arc-shaped plate via a first spring.

[0012] Specifically, when cleaning the lead screw, the second motor is started to drive the bidirectional lead screw to rotate. The bidirectional lead screw drives the clamping plates on both sides to slide. When the arc plate contacts the outside of the lead screw, the arc plate squeezes the first spring, which prevents the brush from excessively squeezing the lead screw and causing excessive wear to the lead screw, thus increasing the service life of the brush.

[0013] Preferably, the upper end of the irregularly shaped slider is provided with a lubricating oil tank, the middle part of the irregularly shaped slider is provided with an irregularly shaped groove, and the lower end of the lubricating oil tank is provided with a rectangular hole corresponding to the position of the irregularly shaped groove.

[0014] Specifically, after the lead screw has been used for a long time, it needs to be lubricated regularly to prevent jamming. Lubricating oil is added to the lubricating oil tank, and the lubricating oil flows from the rectangular hole into the irregular groove in the middle of the irregular slider, so that the lubricating oil comes into contact with the lead screw and lubricates the lead screw.

[0015] Preferably, rectangular grooves are provided on both sides of the lower end of the lubricating oil tank, and sliding plates are slidably connected in the rectangular grooves. A rack is fixedly connected to one side of the sliding plate, and a gear meshes with the rack. The gear is fixedly connected to the upper end of the bidirectional lead screw.

[0016] Specifically, when the bidirectional lead screw rotates, it drives the gear to rotate. The rotation of the gear drives the rack to slide to one side. The sliding of the rack simultaneously drives the slide plate to slide, causing the slide plate to slide to both sides of the rectangular hole. When the bidirectional lead screw is driven to rotate to clean the lead screw, lubricating oil flows out from the rectangular hole and contacts the lead screw, thus lubricating the lead screw while cleaning.

[0017] Preferably, the method further includes a detection component, which includes a first telescopic rod fixedly connected to the lower end of the irregularly shaped slider, a U-shaped block fixedly connected to the lower end of the first telescopic rod, a second spring sleeved on the outer side of the first telescopic rod, a wheel rotatably connected to the middle of the U-shaped block, and a speed detector fixedly connected to one side of the wheel.

[0018] Specifically, when the lead screw drives the irregularly shaped slider to slide, the lower end of the irregularly shaped slider rolls on the rectangular plate through the first telescopic rod wheel. The second spring on the outside of the first telescopic rod pushes down on the U-shaped block to increase the friction between the wheel and the rectangular plate and prevent slippage. A speed detector is provided on one side of the wheel to determine the speed of the wheel. When the speed of the wheel slows down, it indicates that the lead screw is stuck and needs to be cleaned.

[0019] Preferably, an electromagnet is rotatably connected between the two columns, a motor is fixedly connected to one side of the electromagnet via a pin, a hydraulic rod is fixedly connected inside the column, and the output end of the hydraulic rod is fixedly connected to one side of the motor.

[0020] Specifically, when processing a workpiece, iron filings are generated. At this time, the electromagnet is activated to generate magnetic force to attract the iron filings. The motor is started to drive the electromagnet to rotate, so that the electromagnet can attract the filings from all sides. When the column drives the cutter head to work, it also drives the electromagnet to move. When the height of the cutter head is adjusted, the hydraulic rod is activated to drive the electromagnet to adjust its height, so that the electromagnet and the cutter head are always kept on the same horizontal plane, resulting in a good cleaning effect.

[0021] Preferably, the upper end of the electromagnet is fixedly connected to a third slide rail via a fixing block, the lower end of the third slide rail is slidably connected to a third slide table, the lower end of the third slide table is fixedly connected to a ring, the ring slides on the outer wall of the electromagnet, and pressing blocks are fixedly connected to both sides of the ring.

[0022] Specifically, when there are too many iron filings adsorbed on the outside of the electromagnet, they need to be cleaned and collected. At this time, the third slide rail is activated to drive the ring below the third slide table to slide. The ring drives the squeezing blocks on both sides to slide. The squeezing blocks push the iron filings on the outside of the electromagnet to both sides for collection.

[0023] Preferably, the electromagnet is rotatably connected to two irregular molds, one end of the irregular mold is fixedly connected to a cylindrical block, the end of the cylindrical block away from the irregular mold is fixedly connected to a second circular plate, a rectangular strip is fixedly connected between the irregular mold and the second circular plate, a first circular plate is slidably connected to the outside of the cylindrical block, a first arc-shaped block is fixedly connected to both ends of one side of the first circular plate, the end of the first arc-shaped block away from the first circular plate is an inclined surface, a second telescopic rod is fixedly connected to the lower end of the rectangular strip, a second arc-shaped block is fixedly connected to the end of the second telescopic rod away from the rectangular strip, a fifth spring is sleeved on the outside of the second telescopic rod, the second arc-shaped blocks are fixedly connected to each other by a fourth spring, the end of the second arc-shaped block away from the rectangular strip is an inclined surface, and the inclined surface of one side of the first arc-shaped block fits against the inclined surface of the second arc-shaped block.

[0024] Specifically, when the extrusion block pushes the iron filings to both sides, the iron filings are pushed into the irregular molds provided on both sides. When there are too many iron filings, they are squeezed into blocks in the irregular molds. When the pressure of the first circular plate is too high, the inclined surface where the first arc block and the second arc block overlap reaches a certain pressure value, the first arc block slides to one side and squeezes the second arc block to both sides, squeezing the fifth spring and stretching the fourth spring at the same time, so that the first circular plate slides on the cylindrical block. The iron filings blocks squeezed in the irregular mold fall from both sides, and the cylindrical block automatically resets to one side of the irregular mold, squeezing the iron filings into blocks for collection to prevent workers from being scratched by the iron filings during collection.

[0025] Preferably, a workbench is fixedly connected to the upper end of the base plate, support legs are fixedly connected to the four corners of the lower end of the base plate, rails are provided on both sides of the upper end of the base plate, the column slides on the rails, and a collection box is fixedly connected to one side of each column.

[0026] Specifically, the support legs support the base plate, the worktable above the base plate facilitates fixing the workpiece for processing, the column slides on the track to process the workpiece, and the collection box facilitates the collection of iron filings.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. The CNC gantry machining center of the present invention drives a bidirectional lead screw to slide the clamping plates on both sides. The clamping plates drive the brushes on the arc plate to clean the lead screw. When the arc plate contacts the outer side of the lead screw, the arc plate squeezes the first spring to avoid excessive pressure of the brush on the lead screw and cause excessive wear to the lead screw, thereby increasing the service life of the brush.

[0029] 2. The CNC gantry machining center of the present invention drives a bidirectional lead screw to rotate, which in turn drives a gear to rotate. The rotation of the gear drives a rack to slide to one side, and the sliding of the rack simultaneously drives a slide plate to slide to both sides of a rectangular hole. When the bidirectional lead screw is driven to rotate to clean the lead screw, lubricating oil flows out from the rectangular hole and contacts the lead screw, thus lubricating the lead screw while cleaning.

[0030] 3. The CNC gantry machining center of the present invention pushes iron filings to both sides by driving the extrusion block. The iron filings are pushed into the irregular molds provided on both sides. When there are too many iron filings, they are squeezed into blocks in the irregular molds. When the pressure of the first circular plate is too high, the inclined surface of the first arc block and the second arc block reaches a certain pressure value. The first arc block slides to one side and squeezes the second arc block to both sides, squeezing the fifth spring and stretching the fourth spring at the same time, so that the first circular plate slides on the cylindrical block. The iron filings squeezed in the irregular mold fall from both sides, and the iron filings are squeezed into blocks and then collected to prevent workers from being scratched by iron filings during collection.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Example 1

[0042] like Figure 1-2 As shown in the embodiment of the present invention, a CNC gantry machining center includes a base plate 1. Columns 2 are slidably connected to both sides of the upper end of the base plate 1. A sliding assembly is provided at the upper end of each column 2, which is used to drive the cutting head 34 to slide. A shaped slider 21 is fixedly connected to one side of each column 2. A lead screw 15 is threadedly connected to the middle of the shaped slider 21. Clamping mechanisms are provided on both sides of the shaped slider 21. The clamping mechanisms include clamping plates 211 on both sides of the lead screw 15. An arc-shaped plate 212 is elastically connected to the inner side of the clamping plate 211, and a brush 213 is provided on the inner side of the arc-shaped plate 212.

[0043] Specifically, during use, the workpiece is placed on the base plate 1, and the cutting head 34 is moved by the sliding assembly to process the workpiece. The drive screw 15 rotates and drives the irregularly shaped slider 21 to slide. The irregularly shaped slider 21 drives the cutting head 34 on the column 2 to slide, which facilitates processing of the workpiece over a wide range. During use, impurities may accumulate in the gaps of the screw 15, causing jamming, which requires regular cleaning. When the speed of the screw 15 slows down and cleaning is required, the clamping plates 211 on both sides of the drive screw 15 move closer to the screw 15. The clamping plates 211 drive the brush 213 on the arc plate 212 to clean the screw 15.

[0044] like Figure 1As shown, rectangular blocks 13 are fixedly connected to the four corners of the base plate 1, a rectangular plate 17 is fixedly connected between two rectangular blocks 13, an irregular block 14 is fixedly connected to the upper end of the rectangular blocks 13, a lead screw 15 is rotatably connected between two irregular blocks 14, and a first motor 16 that drives the lead screw 15 to rotate is fixedly connected to one side of the rectangular blocks 13.

[0045] The sliding assembly includes a first slide rail 3 fixedly connected to the upper end of the column 2, a first slide table 31 slidably connected to the first slide rail 3, a second slide rail 32 fixedly connected to one side of the first slide table 31, a second slide table 33 slidably connected to the second slide rail 32, and the lower end of the second slide table 33 fixedly connected to the cutter head 34.

[0046] Specifically, when processing the workpiece, the first motor 16 is started to drive the lead screw 15 to rotate. The lead screw 15 drives the column 2 to slide above the base plate 1 through the irregular slider 21. The first slide rail 3 is started to drive the first slide table 31 to slide. The second slide rail 32 is started to drive the second slide table 33 to drive the cutter head 34 to slide, so that the cutter head 34 can move in multiple directions to process the workpiece, which can adapt to workpieces of different thicknesses.

[0047] like Figure 3 As shown, the clamping mechanism also includes a bidirectional lead screw 215 threadedly connected to the clamping plate 211. The bidirectional lead screw 215 is rotatably mounted on the side wall of the column 2 via two fixing blocks. A second motor 216 that drives the bidirectional lead screw 215 to rotate is installed above one of the fixing blocks. The inner side of the clamping plate 211 is fixedly connected to the arc plate 212 via a first spring 214.

[0048] Specifically, when cleaning the lead screw 15, the second motor 216 is started to drive the bidirectional lead screw 215 to rotate. The bidirectional lead screw 215 drives the clamping plates 211 on both sides to slide. When the arc plate 212 contacts the outside of the lead screw 15, the arc plate 212 squeezes the first spring 214 to prevent the brush 213 from excessively squeezing the lead screw 15 and causing excessive wear to the lead screw 15, thereby increasing the service life of the brush 213.

[0049] like Figure 4 As shown, the upper end of the irregularly shaped slider 21 is provided with a lubricating oil tank 22, the middle part of the irregularly shaped slider 21 is provided with an irregularly shaped groove 24, and the lower end of the lubricating oil tank 22 is provided with a rectangular hole 23 corresponding to the position of the irregularly shaped groove 24.

[0050] Specifically, after the lead screw has been used for a long time, it needs to be lubricated regularly to prevent jamming. Lubricating oil is added to the lubricating oil tank 22, and the lubricating oil flows from the rectangular hole 23 into the irregular groove 24 in the middle of the irregular slider 21, so that the lubricating oil comes into contact with the lead screw 15 and lubricates the lead screw 15.

[0051] like Figure 3-4As shown, rectangular grooves are provided on both sides of the lower end of the lubricating oil tank 22. Slide plates 222 are slidably connected in the rectangular grooves. A rack 223 is fixedly connected to one side of the slide plate 222. The rack 223 meshes with a gear 221. The gear 221 is fixedly connected to the upper end of the bidirectional lead screw 215.

[0052] Specifically, when the bidirectional lead screw 215 rotates, it drives the gear 221 to rotate. The rotation of the gear 221 drives the rack 223 to slide to one side. The sliding of the rack 223 simultaneously drives the slide plate 222 to slide, causing the slide plate 222 to slide to both sides of the rectangular hole. When the bidirectional lead screw 215 is driven to rotate to clean the lead screw 15, lubricating oil flows out from the rectangular hole and contacts the lead screw 15. The lead screw 15 can be lubricated at the same time as cleaning.

[0053] Example 2

[0054] like Figure 5 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the invention further includes a detection component, the detection component including a first telescopic rod 4 fixedly connected to the lower end of the irregularly shaped slider 21, a U-shaped block 42 fixedly connected to the lower end of the first telescopic rod 4, a second spring 41 sleeved on the outer side of the first telescopic rod 4, a wheel 43 rotatably connected to the middle of the U-shaped block 42, and a speed detector 44 fixedly connected to one side of the wheel 43.

[0055] Specifically, when the lead screw 15 drives the irregularly shaped slider 21 to slide, the lower end of the irregularly shaped slider rolls on the rectangular plate 17 via the wheel 43 of the first telescopic rod 4. The second spring 41 provided on the outside of the first telescopic rod 4 pushes down on the U-shaped block 42 to increase the friction between the wheel 43 and the rectangular plate 17 and prevent slippage. A speed detector 44 is provided on one side of the wheel 43 to determine the rotation speed of the wheel 43. When the rotation speed of the wheel 43 slows down, it indicates that the lead screw 16 is stuck and needs to be cleaned.

[0056] like Figure 1 As shown, an electromagnet 5 is rotatably connected between the two columns 2. A motor is fixedly connected to one side of the electromagnet 5 via a pin. A hydraulic rod is fixedly connected inside the column 2, and the output end of the hydraulic rod is fixedly connected to one side of the motor.

[0057] Specifically, when processing a workpiece, iron filings are generated. At this time, the electromagnet 5 is activated to generate magnetic force to attract the iron filings. The motor is started to drive the electromagnet 5 to rotate, so that the electromagnet 5 can attract the iron filings from all sides. When the column 2 drives the cutter head 34 to work, it also drives the electromagnet 5 to move. When the height of the cutter head 34 is adjusted, the hydraulic rod is activated to drive the electromagnet 5 to adjust its height, so that the electromagnet 5 and the cutter head 34 are always kept on the same horizontal plane, resulting in a good cleaning effect.

[0058] like Figure 6As shown, the upper end of the electromagnet 5 is fixedly connected to a third slide rail 51 via a fixing block. The lower end of the third slide rail 51 is slidably connected to a third slide table 52. The lower end of the third slide table 52 is fixedly connected to a ring 53. The ring 53 slides on the outer wall of the electromagnet 5. Pressing blocks 54 are fixedly connected to both sides of the ring 53.

[0059] Specifically, when there are too many iron filings adsorbed on the outside of the electromagnet 5, they need to be cleaned and collected. At this time, the third slide rail 51 is activated to drive the ring 53 below the third slide table 52 to slide. The ring 53 drives the squeezing blocks 54 on both sides to slide. The squeezing blocks 54 push the iron filings on the outside of the electromagnet 5 to both sides for collection.

[0060] like Figure 7 As shown, the electromagnet 5 is rotatably connected to a shaped mold 6 at both ends. A cylindrical block 610 is fixedly connected to one end of the shaped mold 6. A second circular plate 68 is fixedly connected to the end of the cylindrical block 610 away from the shaped mold 6. A rectangular strip 69 is fixedly connected between the shaped mold 6 and the second circular plate 68. A first circular plate 61 is slidably connected to the outside of the cylindrical block 610. A first arc-shaped block 62 is fixedly connected to both ends of one side of the first circular plate 61. The end of the first arc-shaped block 62 away from the first circular plate 61 is an inclined surface. A second telescopic rod 66 is fixedly connected to the lower end of the rectangular strip 69. A second arc-shaped block 64 is fixedly connected to the end of the second telescopic rod 66 away from the rectangular strip 69. A fifth spring 67 is sleeved on the outside of the second telescopic rod 66. The second arc-shaped blocks 64 are fixedly connected to each other by a fourth spring 65. The end of the second arc-shaped block 64 away from the rectangular strip 69 is an inclined surface. The inclined surface of one side of the first arc-shaped block 62 fits against the inclined surface of the second arc-shaped block 64.

[0061] Specifically, when the extrusion block 54 pushes the iron filings to both sides, the iron filings are pushed into the irregular molds 6 provided on both sides. When there are too many iron filings, they are squeezed into blocks in the irregular molds 6. When the pressure of the first circular plate 61 is too high, when the inclined surface of the first arc block 62 and the second arc block 64 reaches a certain pressure value, the first arc block 62 slides to one side and squeezes the second arc block 64 to both sides, squeezing the fifth spring 67 and stretching the fourth spring 65 at the same time, so that the first circular plate 61 slides on the cylindrical block 610. The iron filings blocks squeezed in the irregular molds 6 fall from both sides, and the cylindrical block 610 automatically resets to one side of the irregular molds 6, squeezing the iron filings into blocks for collection to prevent workers from being scratched by the iron filings during collection.

[0062] like Figure 1-2 As shown, a workbench 11 is fixedly connected to the upper end of the base plate 1, and support legs 12 are fixedly connected to the four corners of the lower end of the base plate 1. Tracks are provided on both sides of the upper end of the base plate 1, and the column 2 slides on the track. A collection box 7 is fixedly connected to one side of the column 2.

[0063] Specifically, the support leg 12 supports the base plate 1, the workbench 11 above the base plate facilitates fixing the workpiece for processing, the column 2 slides on the track to process the workpiece, and the collection box 7 facilitates the collection of iron filings.

[0064] Working principle: When processing a workpiece, the first motor 16 is started, driving the lead screw 15 to rotate. The lead screw 15 drives the column 2 to slide above the base plate 1 via the irregularly shaped slider 21. The first slide rail 3 is started, driving the first slide table 31 to slide. The second slide rail 32 is started, driving the second slide table 33 to slide the cutter head 34, allowing the cutter head 34 to move in multiple directions to process the workpiece, adapting to workpieces of different thicknesses. When the lead screw 15 drives the irregularly shaped slider 21 to slide, the lower end of the irregularly shaped slider rolls on the rectangular plate 17 via the wheel 43 of the first telescopic rod 4. The second spring 41 on the outside of the first telescopic rod 4 pushes down on the U-shaped block 42 to increase the friction between the wheel 43 and the rectangular plate 17, preventing impact. The wheel 43 is equipped with a speed detector 44 on one side. The speed detector 44 determines the rotation speed of the wheel 43. When the rotation speed of the wheel 43 slows down, it indicates that the lead screw 16 is stuck and needs to be cleaned. When the wheel 43 is detected to be slowing down, the second motor 216 is started to drive the bidirectional lead screw 215 to rotate. The bidirectional lead screw 215 drives the clamping plates 211 on both sides to slide. The clamping plates 211 drive the brush 213 on the arc plate 212 to clean the lead screw 15. When the arc plate 212 contacts the outside of the lead screw 15, the arc plate 212 squeezes the first spring 214 to prevent the brush 213 from excessively squeezing the lead screw 15 and causing excessive wear, thus increasing the service life of the brush 213.

[0065] After prolonged use, the lead screw needs to be lubricated regularly to prevent jamming. When the bidirectional lead screw 215 rotates, it drives the gear 221 to rotate. The rotation of the gear 221 drives the rack 223 to slide to one side. The sliding of the rack 223 simultaneously drives the slide plate 222 to slide, causing the slide plate 222 to slide to both sides of the rectangular hole. When the bidirectional lead screw 215 is rotated to clean the lead screw 15, lubricating oil flows out from the rectangular hole and comes into contact with the lead screw 15. The lead screw 15 can be lubricated at the same time as cleaning.

[0066] When machining a workpiece, iron filings are generated. At this time, the electromagnet 5 is activated to generate magnetic force, attracting the iron filings. The motor then rotates the electromagnet 5, allowing it to attract filings from all sides. The column 2 moves the cutter head 34 while simultaneously moving the electromagnet 5. When the cutter head 34 is adjusted in height, the hydraulic rod is activated to adjust the height of the electromagnet 5, ensuring that the electromagnet 5 and the cutter head 34 are always on the same horizontal plane for good cleaning. When too many iron filings are attracted to the outside of the electromagnet 5, they need to be cleaned and collected. At this time, the third slide rail 51 is activated, causing the ring 53 below the third slide table 52 to slide. The ring 53 then moves the pressing blocks 54 on both sides, causing the pressing blocks 54 to press the iron filings on the outside of the electromagnet 5. Iron filings are pushed to both sides for collection. When the extrusion block 54 pushes the iron filings to both sides, the iron filings are pushed into the irregular molds 6 provided on both sides. When there are too many iron filings, they are squeezed into blocks in the irregular molds 6. When the pressure of the first circular plate 61 is too high, the inclined surface of the first arc block 62 and the second arc block 64 reaches a certain pressure value. The first arc block 62 slides to one side and squeezes the second arc block 64 to both sides, squeezing the fifth spring 67 and stretching the fourth spring 65 at the same time, so that the first circular plate 61 slides on the cylindrical block 610. The iron filings blocks squeezed in the irregular molds 6 fall from both sides. The cylindrical block 610 automatically resets to one side of the irregular molds 6, squeezing the iron filings into blocks for collection to prevent workers from being scratched by iron filings during collection.
