Description

A horizontal machining center that improves machining accuracy Technical Field

[0001] This invention relates to the field of machining centers, and more specifically to a horizontal machining center that is advantageous for improving machining accuracy. Background Technology

[0002] With the rapid development of science and technology, industrial processing methods have become increasingly diverse. While meeting the ever-growing processing and manufacturing demands of today's society, advanced technologies can also help enterprises achieve higher economic returns. Precision horizontal machining centers are fundamental equipment for manufacturing precision machine tools and other high-precision machines, ensuring the development of cutting-edge industries. Precision horizontal machining centers are suitable for the precision machining of complex parts such as box-shaped, disc-shaped, plate-shaped, and mold-shaped components. They are essential equipment for precision parts processing in military, aerospace, aviation, cutting tool, mold, and machinery manufacturing industries.

[0003] Currently, my country ranks among the world's leading producers and consumers of domestically manufactured precision horizontal machining centers. These centers are capable of performing various machining operations, including milling, boring, drilling, reaming, tapping, and machining two-dimensional and three-dimensional curved surfaces. Horizontal machining centers are widely used in aerospace manufacturing, mining and metallurgy, and military equipment, among other fields. However, the precision and stability of domestically produced horizontal machining centers still lag significantly behind advanced international levels. Therefore, improving the precision and stability of horizontal machining centers is crucial for developing advanced precision horizontal machining centers and increasing market share. Summary of the Invention

[0004] The purpose of this invention is to provide a horizontal machining center that improves machining accuracy and stability.

[0005] The technical solution of this invention is:

[0006] A horizontal machining center that improves machining accuracy includes:

[0007] The machine tool bed has a worktable.

[0008] The longitudinal traverse includes a longitudinal front guide rail and a longitudinal rear guide rail that are mounted on the machine tool bed and are parallel to each other. The longitudinal front guide rail is located between the worktable and the longitudinal rear guide rail, and the height of the longitudinal front guide rail is lower than the height of the longitudinal rear guide rail.

[0009] The machine tool column moves along a longitudinal traverse track. A column notch is located at the bottom of the column. The front longitudinal traverse guide rail is located below the bottom of the column, and the rear longitudinal traverse guide rail is located within and passes through the column notch. Because the longitudinal traverse track uses a stepped distribution with a lower front and higher rear (the height of the front longitudinal traverse guide rail is lower than the height of the rear longitudinal traverse guide rail), the column notch at the bottom of the column, which mates with the rear longitudinal traverse guide rail, can significantly reduce the weight of the machine tool column as a moving component, while ensuring the strength of the machine tool column (i.e., ensuring the strength of the Z-axis of the horizontal machining center). This allows the machine tool column to achieve higher movement accuracy, thereby improving the machining accuracy of the horizontal machining center and achieving higher acceleration performance and movement speed. Simultaneously, during the cutting process of the horizontal machining center, it also helps to counteract the cutting resistance of the Z-axis, effectively preventing backward deformation of the machine tool column and thus improving the stability of the horizontal machining center.

[0010] As a preferred option, it also includes:

[0011] The vertical track is set on the side of the machine tool column facing the worktable. The vertical track includes two vertical guide rails, left and right. The machine tool column is provided with a spindle motor receiving cavity that extends vertically, and the spindle motor receiving cavity is located between the two vertical guide rails.

[0012] The lifting platform moves up and down along a vertical track;

[0013] The spindle box, mounted on the lifting platform, includes the machine tool spindle and the spindle motor that drives its rotation. The spindle motor is located within its housing. Because the spindle motor housing is situated between two vertical guide rails, and the motor itself is located within this housing, it offers several advantages. First, it improves the stability of the spindle box's movement along the vertical rails, thus enhancing the overall stability of the horizontal machining center. Second, since the spindle motor is a major heat-generating component in the horizontal machining center, arranging the two vertical guide rails on either side of the motor ensures synchronized thermal expansion and contraction, avoiding significant differences in deformation due to thermal expansion and contraction.

[0014] Preferably, the machine tool column includes left and right column components, a bottom component connecting the bottom of the left and right column components, and a top component connecting the top of the left and right column components. The space between the left and right column components forms the spindle motor receiving cavity, and two vertical guide rails are arranged on the two column components in a one-to-one correspondence.

[0015] As a preferred option, the machine tool column also includes:

[0016] The column reinforcement corresponds one-to-one with the column components and is installed on the machine tool column on the side facing away from the worktable.

[0017] The reinforced connection connects the bottom of the column reinforcements on the two column components into one piece; the column notch is located below the reinforced connection.

[0018] Preferably, the column component is a hollow structure, and its surface has several ventilation openings that communicate with the hollow structure. This reduces the weight of the column component and the machine tool column itself, allowing for higher movement accuracy and thus improving the machining accuracy of the horizontal machining center. Furthermore, it improves heat dissipation, reducing the impact of thermal expansion and contraction on machining accuracy.

[0019] Preferably, the system also includes a lifting actuator that drives the lifting seat to move up and down along the vertical track. The lifting actuator includes a vertical lead screw that is parallel to the vertical guide rail and is located within the main spindle motor housing.

[0020] Preferably, a longitudinal traverse actuator is also included, which drives the machine tool column to move along the longitudinal traverse track, and the longitudinal traverse actuator is located within the column notch. This helps to improve the structural compactness.

[0021] Preferably, the system also includes a magnetic separator for purifying the coolant, the magnetic separator comprising:

[0022] A magnetic roller has an outer circumferential surface comprising a magnetically absorbing area and a non-magnetically absorbing area. The magnetically absorbing area and the non-magnetically absorbing area are alternately distributed along the circumference of the magnetic roller and rotate synchronously with the magnetic roller. A flow-blocking groove is also provided on the outer circumferential surface of the magnetic roller where the non-magnetically absorbing area is located. The flow-blocking groove extends along the axial direction of the magnetic roller and at least one end of the flow-blocking groove is connected to the end of the magnetic roller.

[0023] The extrusion roller presses against the surface of the magnetic drum to squeeze out the coolant entrained in the iron filings and impurities.

[0024] The scraper is used to scrape off iron filings and other impurities adsorbed on the magnetic roller.

[0025] Currently, the outer circumference of the magnetic drum in existing magnetic separators is generally a magnetic absorption area capable of adsorbing iron filings and impurities from the coolant. The squeeze roller presses against the surface of the magnetic drum, squeezing out the coolant entrained in the iron filings and impurities to prevent the coolant from being carried out along with the iron filings and impurities when the scraper removes them from the magnetic drum. However, when processing oily coolant, a continuous oil film (i.e., an oily coolant film) often forms on the outer circumference of the magnetic drum. Because of this oil film, the squeeze roller often struggles to expel it due to the influence of iron filings and impurities (especially when the iron filings and impurities are large). This results in the scraper subsequently scraping away both the iron filings and the oil film, carrying away the coolant. To address this issue, this solution involves setting magnetic and non-magnetic areas on the outer circumference of the magnetic roller (magnetic areas can adsorb iron filings and impurities, while non-magnetic areas cannot). These magnetic and non-magnetic areas are alternately distributed along the circumference of the magnetic roller and rotate synchronously with it. During the rotation of the magnetic roller, iron filings and impurities in the coolant are adsorbed through the outer circumference of the magnetic roller where the magnetic areas are located. The outer circumference of the magnetic roller where the non-magnetic areas are located is free of iron filings and impurities, and the extrusion roller passes through the non-magnetic areas. As the extrusion roller passes through the non-magnetic region, it directly squeezes the outer circumference of the magnetic roller in that region. This serves two purposes: firstly, it extrudes the oil film from the non-magnetic region. Part of the extruded oil film flows back into the coolant tank through both ends of the magnetic roller, while the other part flows down the outer circumference of the magnetic roller into the flow-blocking groove, and then back into the coolant tank through the groove's port. This prevents the extruded oil film from flowing down the outer circumference of the magnetic roller into the iron filings and impurities of the next magnetic region. Secondly, because the extrusion roller extrudes the oil film from the non-magnetic region, it disrupts the formation of a continuous oil film on the outer circumference of the magnetic roller, thus reducing the amount of oily coolant carried onto the outer circumference of the magnetic roller. Simultaneously, during the separation of the non-magnetic region from the coolant tank, since there is no iron filings or impurities carrying coolant in the non-magnetic region, a large portion of the oily coolant adhering to the outer circumference of the magnetic roller in the non-magnetic region will slide back into the coolant tank under its own weight, further reducing the amount of oily coolant carried onto the outer circumference of the magnetic roller and minimizing coolant carry-out.

[0026] Preferably, the magnetic separator also includes an adaptive baffle device corresponding to each flow-blocking groove, the adaptive baffle device comprising:

[0027] The baffle is rotated and is set inside the opening of the flow-blocking groove via a rotating shaft;

[0028] A limiting protrusion is set at the opening of the flow-blocking groove to limit the rotation of the baffle.

[0029] The magnetic attracting component is installed on one of the rotating baffle and the limiting protrusion. When the rotating baffle approaches or abuts against the limiting protrusion, the magnetic attracting component attracts the rotating baffle and the limiting protrusion together. At this time, the rotating baffle blocks the opening of the flow channel.

[0030] During the rotation of the magnetic roller, when the adaptive baffle device approaches the extrusion roller, the rotating baffle of the adaptive baffle device rotates downward around the rotating shaft under its own weight and separates from the limiting protrusion. When the adaptive baffle device approaches the scraper plate, the rotating baffle of the adaptive baffle device rotates downward around the rotating shaft under its own weight and is attracted together with the limiting protrusion by the magnetic attracting component.

[0031] The design of the flow-restricting grooves in the non-magnetic area, while preventing the oil film squeezed out by the extrusion rollers from flowing down the outer circumference of the magnetic roller into the iron filings and impurities in the next magnetic area, also means that as the flow-restricting grooves approach the scraper plate, the iron filings and impurities scraped by the scraper plate may fall into the flow-restricting grooves and back into the coolant tank, affecting the efficiency of the scraper plate in removing iron filings and impurities. To solve this problem, this solution specifically incorporates an adaptive baffle device.

[0032] During the rotation of the magnetic drum, when the adaptive baffle device approaches the extrusion roller, its rotating baffle, under its own weight, rotates downward around the axis and separates from the limiting protrusion, opening the opening of the flow-blocking groove. This prevents the oil film extruded from the extrusion roller from flowing downward along the outer circumference of the magnetic drum into the iron filings and impurities in the next magnetic attraction area. When the adaptive baffle device approaches the scraper plate, its rotating baffle, again under its own weight, rotates downward around the axis and is attracted to the limiting protrusion by the magnetic attraction component. This seals the opening of the flow-blocking groove, preventing the iron filings and impurities scraped by the scraper plate from falling into the flow-blocking groove and back into the coolant tank as the flow-blocking groove approaches the scraper plate.

[0033] Preferably, the surface of the extrusion roller is provided with a discharge groove, which extends along the axial direction of the extrusion roller. Since the extrusion roller is in close contact with the surface of the magnetic drum, when encountering larger iron filings or impurities, these larger particles may be unable to pass through the extrusion roller, accumulating at the extrusion roller and falling back into the coolant tank. To solve this problem, this solution specifically incorporates a discharge groove. When larger iron filings or impurities accumulate at the extrusion roller, each rotation of the extrusion roller will allow these larger particles to pass through the discharge groove and pass through the extrusion roller, effectively preventing these larger iron filings or impurities from being unable to pass through the extrusion roller, accumulating at the extrusion roller, and falling back into the coolant tank.

[0034] The beneficial effects of this invention are that it can improve the machining accuracy and stability of horizontal machining centers. Attached Figure Description

Detailed Implementation

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0053] Specific embodiment one, as shown in Figures 1, 2, 3, and 4, describes a horizontal machining center that improves machining accuracy, comprising a machine bed 1, a machine column 3, and a longitudinal traverse track 4. A worktable 2 is provided on the machine bed. The longitudinal traverse track includes a front longitudinal guide rail 4.1 and a rear longitudinal guide rail 4.2, which are parallel to each other and mounted on the machine bed. The longitudinal traverse tracks are horizontally distributed. The front longitudinal guide rail is located between the worktable and the rear longitudinal guide rail, and its height is lower than that of the rear longitudinal guide rail. The machine column 3 moves along the longitudinal traverse track. A column notch 3.1 is provided at the bottom of the machine column. The front longitudinal guide rail is located between the column notch and the worktable. The front longitudinal guide rail is located below the bottom of the machine column, and the bottom of the machine column is connected to a slider on the front longitudinal guide rail. The rear longitudinal guide rail is located within and passes through the column notch, and the inner top surface of the column notch is connected to a slider on the rear longitudinal guide rail.

[0054] Because the longitudinal traverse rails adopt a stepped distribution with a lower front and higher rear (the height of the front longitudinal traverse rail is lower than the height of the rear longitudinal traverse rail), a column notch can be arranged at the bottom of the machine tool column to cooperate with the rear longitudinal traverse rail, while ensuring the strength of the machine tool column (i.e., ensuring the strength of the Z-axis of the horizontal machining center). This greatly reduces the weight of the machine tool column as a moving part, enabling the machine tool column to achieve higher movement accuracy, thereby improving the machining accuracy of the horizontal machining center and achieving higher acceleration performance and movement speed. At the same time, during the cutting process of the horizontal machining center, it also helps to counteract the cutting resistance of the Z-axis, effectively avoiding the backward deformation of the machine tool column, thereby improving the stability of the horizontal machining center.

[0055] Specifically, as shown in Figures 1, 2, 3, and 4, a horizontal machining center that improves machining accuracy further includes a transverse track 8, a vertical track 5, a lifting seat 6, a spindle box 7, a longitudinal movement actuator, a lifting actuator, and a transverse movement actuator. The transverse track is mounted on the machine tool bed. The transverse track is horizontally distributed and perpendicular to the longitudinal track. The worktable moves along the transverse track. The transverse movement actuator is mounted on the machine tool bed and drives the worktable to move along the transverse track. The longitudinal movement actuator drives the machine tool column to move along the longitudinal track, and the longitudinal movement actuator is located within a notch in the column. The specific structures of the transverse and longitudinal movement actuators are existing technology and are not the inventive point of this application. Therefore, this application will not elaborate on the specific methods and structures of the transverse and longitudinal movement actuators or other conventional technical means.

[0056] The vertical rail 5 is located on the side of the machine tool column facing the worktable. The vertical rails are vertically distributed and include two guide rails, one on the left and one on the right. The machine tool column has a spindle motor housing 3.2 extending vertically, situated between the two vertical guide rails. The lifting platform moves up and down along the vertical rails. The spindle box is mounted on the lifting platform. The spindle box includes the machine tool spindle and the spindle motor that drives its rotation; the spindle motor is located within the spindle motor housing. The lifting actuator drives the lifting platform to move up and down along the vertical rails. Because the spindle motor housing is located between the two vertical guide rails, and the spindle motor is located within the housing, this improves the stability of the spindle box moving up and down along the vertical rails, thus enhancing the stability of the horizontal machining center. Furthermore, since the spindle motor is a major heat-generating component in the horizontal machining center, arranging the two vertical guide rails on either side of the motor allows for synchronized thermal expansion and contraction, avoiding significant differences in deformation due to thermal expansion and contraction.

[0057] In this embodiment, the lifting actuator includes a vertical lead screw parallel to the vertical guide rail, a lifting motor for driving the vertical lead screw to rotate, and a nut that cooperates with the vertical lead screw. The vertical lead screw is rotatably mounted on the machine tool column and is located within the spindle motor housing. The nut is fixed to the lifting seat. The lifting motor is mounted on the top of the machine tool column.

[0058] Furthermore, as shown in Figures 2, 3, and 4, the machine tool column 3 includes left and right column components 3.3, a bottom component 3.4 connecting the bottom of the left and right column components, and a top component 3.5 connecting the top of the left and right column components. The space between the left and right column components constitutes the spindle motor receiving cavity, and two vertical guide rails are correspondingly arranged on the two column components.

[0059] The machine tool column also includes a column reinforcement 3.6 and a reinforcing connection 3.7. The column reinforcement corresponds one-to-one with the column components. The column reinforcement is located on the machine tool column on the side facing away from the worktable. The reinforcing connection connects the bottoms of the column reinforcements on the two column components into one unit. The column reinforcement is triangular in shape. The column notch is located below the reinforcing connection.

[0060] Furthermore, the column component is a hollow structure, and its surface has several ventilation openings that are connected to the hollow structure. This reduces the weight of the column component and the machine tool column itself, allowing for higher movement accuracy and thus improving the machining accuracy of the horizontal machining center. It also improves heat dissipation, reducing the impact of thermal expansion and contraction on machining accuracy.

[0061] Furthermore, as shown in Figure 5, a horizontal machining center that improves machining accuracy also includes a magnetic separator 9 for purifying the coolant. The magnetic separator includes a coolant tank 9.1, a magnetic roller 9.2, a squeeze roller 9.3, and a scraper 9.4. The coolant tank has a cavity for storing coolant. The magnetic roller is located inside the coolant tank and is used to adsorb iron filings and impurities from the coolant. The squeeze roller abuts against the surface of the magnetic roller, squeezing out the coolant entrained in the iron filings and impurities. The scraper is used to scrape off the iron filings and impurities adsorbed on the magnetic roller. After use during operation, the coolant from the horizontal machining center is discharged into the coolant tank, and the magnetic roller draws out the iron filings and impurities, keeping the coolant clean.

[0062] In this embodiment, the outer circumferential surface of the magnetic roller 9.2 includes a magnetically attracting region 9.5 and a non-magnetically attracting region 9.6. The magnetically attracting region refers to the magnetic region capable of attracting iron filings and impurities, while the non-magnetically attracting region refers to the region unable to attract iron filings and impurities. The magnetically attracting and non-magnetically attracting regions are alternately distributed along the circumference of the magnetic roller, and they rotate synchronously with the magnetic roller. The boundary lines between the magnetically attracting and non-magnetically attracting regions are distributed along the axial direction of the magnetic roller. The width of the magnetically attracting region along the circumference of the magnetic roller is greater than the width of the non-magnetically attracting region along the circumference of the magnetic roller. In this embodiment, the magnetic roller includes an outer cylinder and several magnet regions 9.8 disposed on the inner wall of the outer cylinder. Each magnet region is evenly distributed along the circumference of the outer cylinder, and a magnet is arranged within each magnet region and fixed to the inner wall of the outer cylinder. There are interval regions 9.9 between the magnet regions. There are no magnets in the interval regions. The region on the outer circumferential surface of the magnetic roller corresponding to the magnet region is the magnetically attracting region. The region on the outer circumferential surface of the magnetic roller corresponding to the interval region between each magnet region is the non-magnetically attracting region.

[0063] A flow-blocking groove 9.7 is also provided on the outer circumferential surface of the magnetic roller where the non-magnetic area is located. The flow-blocking groove extends along the axial direction of the magnetic roller, and at least one end of the flow-blocking groove is connected to the end of the magnetic roller. In this embodiment, the flow-blocking groove passes through both ends of the magnetic roller.

[0064] Currently, the outer circumference of the magnetic drum in existing magnetic separators is generally a magnetic absorption area capable of adsorbing iron filings and impurities from the coolant. The squeeze roller presses against the surface of the magnetic drum, squeezing out the coolant entrained in the iron filings and impurities to prevent the coolant from being carried out along with the iron filings and impurities when the scraper removes them from the magnetic drum. However, when processing oily coolant, a continuous oil film (i.e., an oily coolant film) often forms on the outer circumference of the magnetic drum. Because of this oil film, the squeeze roller often struggles to expel it due to the influence of iron filings and impurities (especially when the iron filings and impurities are large). This results in the scraper subsequently scraping away both the iron filings and the oil film, carrying away the coolant. To address this issue, this solution involves setting magnetic and non-magnetic areas on the outer circumference of the magnetic roller (magnetic areas can adsorb iron filings and impurities, while non-magnetic areas cannot). These magnetic and non-magnetic areas are alternately distributed along the circumference of the magnetic roller and rotate synchronously with it. During the rotation of the magnetic roller, iron filings and impurities in the coolant are adsorbed through the outer circumference of the magnetic roller where the magnetic areas are located. The outer circumference of the magnetic roller where the non-magnetic areas are located is free of iron filings and impurities, and the extrusion roller passes through the non-magnetic areas. As the extrusion roller passes through the non-magnetic region, it directly squeezes the outer circumference of the magnetic roller in that region. This serves two purposes: firstly, it extrudes the oil film from the non-magnetic region. Part of the extruded oil film flows back into the coolant tank through both ends of the magnetic roller, while the other part flows down the outer circumference of the magnetic roller into the flow-blocking groove, and then back into the coolant tank through the groove's port. This prevents the extruded oil film from flowing down the outer circumference of the magnetic roller into the iron filings and impurities of the next magnetic region. Secondly, because the extrusion roller extrudes the oil film from the non-magnetic region, it disrupts the formation of a continuous oil film on the outer circumference of the magnetic roller, thus reducing the amount of oily coolant carried onto the outer circumference of the magnetic roller. Simultaneously, during the separation of the non-magnetic region from the coolant tank, since there is no iron filings or impurities carrying coolant in the non-magnetic region, a large portion of the oily coolant adhering to the outer circumference of the magnetic roller in the non-magnetic region will slide back into the coolant tank under its own weight, further reducing the amount of oily coolant carried onto the outer circumference of the magnetic roller and minimizing coolant carry-out.

[0065] Furthermore, as shown in Figures 5, 6, and 7, the magnetic separator 9 also includes an adaptive baffle device corresponding to each flow-blocking groove. The adaptive baffle device includes a rotating baffle 9.10, a limiting protrusion 9.11, and a magnetic attracting element. The magnetic attracting element is a magnet. The rotating baffle is rotatably disposed within the opening of the flow-blocking groove via a rotating shaft. The rotating shaft is parallel to the rotation axis of the magnetic roller. The limiting protrusion is disposed at the edge of the opening of the flow-blocking groove to limit the rotating baffle. The limiting protrusion and the rotating shaft are located on opposite sides of the opening of the flow-blocking groove. The rotating baffle has a limiting protrusion groove 9.12 that cooperates with the limiting protrusion. The magnetic attracting element is disposed on one of the rotating baffle and the limiting protrusion. In this embodiment, the magnetic attracting element is disposed on the bottom surface of the limiting protrusion groove of the rotating baffle. When the rotating baffle approaches or abuts against the limiting protrusion, the limiting protrusion is located in the groove of the limiting protrusion. The magnetic attracting component attracts the rotating baffle and the limiting protrusion together. At this time, the rotating baffle blocks the opening of the flow channel, and the surface of the rotating baffle is flush with the outer circumference of the magnetic roller.

[0066] As shown in Figure 6, during the rotation of the magnetic roller, when the adaptive baffle device approaches the extrusion roller, the rotating baffle of the adaptive baffle device rotates downward around the rotating shaft under its own weight and separates from the limiting protrusion.

[0067] As shown in Figure 7, during the rotation of the magnetic drum, when the adaptive baffle device approaches the scraper plate, the rotating baffle of the adaptive baffle device rotates downward around the rotating shaft under its own weight and is attracted together with the limiting protrusion by the magnetic attracting component.

[0068] The design of the flow-restricting groove in the non-magnetic area, while preventing the oil film squeezed out by the extrusion roller from flowing down the outer circumference of the magnetic roller into the iron filings and impurities in the next magnetic area, also means that as the flow-restricting groove approaches the scraper plate, the iron filings and impurities scraped by the scraper plate may fall into the flow-restricting groove and back into the coolant tank, affecting the efficiency of the scraper plate in removing iron filings and impurities. To solve this problem, this embodiment specifically incorporates an adaptive baffle device.

[0069] During the rotation of the magnetic drum, when the adaptive baffle device approaches the extrusion roller, its rotating baffle, under its own weight, rotates downward around the axis and separates from the limiting protrusion, opening the opening of the flow-blocking groove. This prevents the oil film extruded from the extrusion roller from flowing downward along the outer circumference of the magnetic drum into the iron filings and impurities in the next magnetic attraction area. When the adaptive baffle device approaches the scraper plate, its rotating baffle, again under its own weight, rotates downward around the axis and is attracted to the limiting protrusion by the magnetic attraction component. This seals the opening of the flow-blocking groove, preventing the iron filings and impurities scraped by the scraper plate from falling into the flow-blocking groove and back into the coolant tank as the flow-blocking groove approaches the scraper plate.

[0070] Furthermore, as shown in Figure 5, a debris removal groove 9.31 is provided on the surface of the extrusion roller 9.3, and the debris removal groove extends along the axial direction of the extrusion roller. The debris removal groove runs through both ends of the extrusion roller. Since the extrusion roller is in close contact with the surface of the magnetic drum, when encountering larger iron filings or impurities, these larger iron filings or impurities may not be able to pass through the extrusion roller, accumulate at the extrusion roller, and fall back into the coolant tank. To solve this problem, this solution specifically sets up a debris removal groove. When larger iron filings or impurities accumulate at the extrusion roller, these larger iron filings or impurities will pass through the debris removal groove and pass through the extrusion roller every time the extrusion roller rotates once, effectively avoiding the problem of these larger iron filings or impurities being unable to pass through the extrusion roller, accumulating at the extrusion roller, and falling back into the coolant tank.

[0071] In this embodiment, there are two extrusion rollers, each with a discharge groove on its surface. The two extrusion rollers are distributed circumferentially along the magnetic drum. When the opening of the discharge groove of one extrusion roller abuts against the surface of the magnetic drum, the opening of the discharge groove of the other extrusion roller separates from the surface of the magnetic drum. Thus, as long as the surface of one of the two extrusion rollers is in close contact with the surface of the magnetic drum, the coolant entrained in the iron filings is squeezed out by the extrusion roller, avoiding the problem that the discharge groove on the surface of the extrusion roller would affect the squeezing out of the coolant entrained in the iron filings.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
