Description

Technical Field

[0001] The present invention relates to the technical field of aluminum casting processing, and specifically relates to a device for removing edge waste of aluminum profile die-castings. Background Art

[0002] Aluminum profile die-castings are metal parts made of aluminum or aluminum alloy through the die-casting process. Their production process combines the characteristics of high pressure and high-speed filling, and can form complex shapes with high surface accuracy. During the production process of cylindrical aluminum profile die-castings, it is necessary to first remove the waste material on the cylindrical edge. In the current removal process, due to the carbonization of the mold release agent remaining on the surface of the die-casting at high cutting temperatures, it will exacerbate tool wear and contaminate the workpiece. Summary of the Invention

[0003] To solve the technical problems in the background art, the present invention proposes a device for removing edge waste of aluminum profile die-castings.

[0004] A device for removing edge waste of aluminum profile die-castings proposed by the present invention includes a frame;

[0005] A turntable installed on the workbench surface of the frame, and a clamping assembly for clamping the lower end of the cylindrical aluminum casting is installed on the turntable;

[0006] A movable arm installed on the side wall of the frame, and a cleaning assembly for removing the mold release agent is installed at the free end of the movable arm and is arranged on the upper edge of the cylindrical aluminum casting;

[0007] A movable plate installed at the upper end of the frame and capable of lifting and lowering, and a die-cutting tool adapted to the upper end of the cylindrical aluminum casting and centered is installed at the lower end of the movable plate;

[0008] A transmission assembly installed on the side wall of the frame, the transmission assembly has two movable ends and is respectively connected to the movable arm and the movable plate. When the movable plate drives the die-cutting tool to move downwards, the movable arm and the cleaning assembly are driven away from the cylindrical aluminum casting through the transmission assembly, so that the upper edge of the cylindrical aluminum casting is exposed;

[0009] An elevator is installed on the back of the frame, and the movable plate is installed on the movable end of the elevator, and the movable plate and the die-cutting tool are driven to lift and lower synchronously through the elevator;

[0010] The turntable, the clamping assembly and the cylindrical aluminum casting are driven to rotate by a motor under the workbench surface, so as to enable the cleaning assembly to clean the upper edge of the cylindrical aluminum casting, improve the efficiency of removing the mold release agent, and cooperate with the downward movement of the die-cutting tool to achieve rotary cutting;

[0011] The turntable and the clamping assembly are used to fix and rotate the cylindrical aluminum casting, providing a stable processing object for the cleaning assembly and the die-cutting tool. The cleaning assembly removes the release agent before processing to avoid its carbonization during subsequent cutting, which may have an adverse effect on the tool and the workpiece. The movable plate and the die-cutting tool are responsible for cutting off the waste. The transmission assembly cleverly realizes the linkage between the movable plate and the movable arm, ensuring that the cleaning assembly does not interfere with the cutting operation during cutting, and the rotating cutting method improves the cutting efficiency and quality.

[0012] As a further optimized solution of the present invention, the transmission assembly includes a gear, a first rack and a second rack. The gear is rotatably installed on the side wall of the frame and meshes with the first rack. One end of the first rack is slidably assembled with the side wall of the frame, and the other end of the first rack horizontally extends above the turntable and is connected to the movable arm. One end of the second rack is installed on the movable plate, and the other end of the second rack moves synchronously with the movable plate and meshes with the gear to drive the gear to rotate;

[0013] This gear-rack transmission structure is simple and reliable. When the movable plate descends, it drives the second rack to move downward. The second rack meshes with the gear, causing the gear to rotate. The rotation of the gear drives the first rack meshing with it to move horizontally. Since the first rack is connected to the movable arm, the movable arm and the cleaning assembly are moved away from the cylindrical aluminum casting, accurately making way for the die-cutting tool to ensure that the cutting process is not hindered by the cleaning assembly and guarantee the smooth progress of the cutting operation.

[0014] As a further optimized solution of the present invention, a longitudinal chute is provided on the side wall of the frame. The end of the movable plate is equipped with a slider that extends into the longitudinal chute and is slidably assembled with the longitudinal chute. The second rack is slidably arranged in the longitudinal chute, and its upper end is fixed to the bottom of the slider. The lower end of the second rack moves synchronously with the movable plate and meshes with the side of the gear, and the second rack is arranged in a staggered manner with the first rack;

[0015] The cooperation of the longitudinal chute and the slider provides stable guidance for the lifting of the movable plate, ensuring that the movable plate moves vertically up and down, enabling the die-cutting tool to accurately cut the cylindrical aluminum casting. The second rack is fixed to the bottom of the slider. As the movable plate moves downward, the second rack can accurately mesh with the gear to transmit power. Being arranged in a staggered manner with the first rack, it avoids the interference between the two racks during movement, ensures the normal operation of the transmission assembly, and improves the stability and reliability of the movement of the entire device.

[0016] As a further optimized solution of the present invention, a jack is provided on the bottom surface of the longitudinal chute opposite to and adapted to the lower end of the second rack. The lower end of the second rack slides into the jack as the movable plate moves downward synchronously;

[0017] The arrangement of the jacks further enhances the stability of the movement of the second rack and the accuracy of positioning. When the movable plate drives the second rack to move downward, the lower end of the second rack inserts into the jacks, restricting the displacement of the second rack in the horizontal direction, enabling it to move only up and down along the longitudinal chute, ensuring that the second rack and the gear always maintain the correct meshing position, preventing transmission failures caused by the displacement of the rack during the cutting process, and ensuring that the movable arm and the cleaning assembly can move away from the cylindrical aluminum casting according to the predetermined motion.

[0018] As a further optimized solution of the present invention, a slide rail is installed on the bottom surface of the longitudinal chute. The first rack is arranged between the gear and the slide rail. The upper end of the first rack has continuous teeth and is meshed and connected with the gear. A transverse chute adapted to the slide rail is provided at the lower end of the first rack. The lower end of the first rack is slidably assembled with the slide rail through the transverse chute.

[0019] The cooperation of the slide rail and the transverse chute provides a stable sliding track for the first rack. Driven by the gear, the lower end of the first rack slides along the slide rail, ensuring the smoothness of the horizontal movement of the first rack, avoiding shaking or deviation during the movement, thereby making the movement of the movable arm and the cleaning assembly more accurate, ensuring that it can accurately move away from the cylindrical aluminum casting during cutting, and improving the working precision of the device.

[0020] As a further optimized solution of the present invention, the cleaning assembly includes a mounting seat and a cleaning brush roll. The mounting seat is installed on the movable arm and is located above the clamping assembly. One end of the cleaning brush roll is rotatably installed on the side of the mounting seat away from the movable arm and is driven by an electric motor. The other end of the cleaning brush roll is placed on the upper edge of the cylindrical aluminum casting. The mounting seat is hingedly installed on the movable arm and is locked by a fastener so as to adjust the inclination angle of the mounting seat and the cleaning brush roll according to the specifications of the cylindrical aluminum casting.

[0021] The cleaning brush roll is driven by an electric motor. The high-speed rotating brush roll can effectively remove the release agent on the upper edge of the cylindrical aluminum casting. The mounting seat is hinged on the movable arm and the inclination angle can be adjusted, which enables the cleaning assembly to adapt to cylindrical aluminum castings of different specifications, ensuring that the cleaning brush roll can always be in good contact with the upper edge of the aluminum casting, improving the removal effect of the release agent, and meeting different production requirements.

[0022] As a further optimized solution of the present invention, the cleaning assembly further includes a connecting arm and a first spray head. One end of the connecting arm is installed on the mounting seat, and the other end of the connecting arm installs the first spray head. The first spray head is arranged obliquely above the cleaning brush roll and is opposite to the upper edge of the cylindrical aluminum casting. The first spray head sprays coolant when the cleaning brush roll is working, facilitating the cleaning and scraping of the release agent on the surface of the aluminum casting by the cleaning brush roll, ensuring the cleanliness of the upper edge of the aluminum casting, and also playing a role in cooling, effectively preventing the carbonization of the release agent caused by frictional heat generation, and further improving the cleaning effect.

[0023] Guide rails are installed on both the front and rear sides of the upper end of the mounting base. A connecting frame is installed at one end of the connecting arm away from the first spray head. The connecting frame is slidably assembled with the guide rail and locked by a fastener to finely adjust the position of the first spray head.

[0024] The first spray head includes an outer housing and an inner spray head. The outer housing is fixedly installed at the end of the connecting arm. The inner spray head is movably assembled in the outer housing through a universal ball and its inclination angle is adjusted by bolts around the housing. The tail end of the inner spray head is connected to the coolant delivery pipe through a hose.

[0025] The positions of the connecting arm and the first spray head can be finely adjusted, and the inclination angle of the inner spray head can also be adjusted, so that the coolant can be accurately sprayed on the part to be cleaned, ensuring the best cleaning effect under different working conditions and meeting the diverse production requirements.

[0026] As a further optimized solution of the present invention, a second spray head is also installed on the side of the mounting base away from the movable arm, and the nozzle of the second spray head faces the upper edge of the cylindrical aluminum casting. The liquid inlet end of the second spray head is connected to the coolant delivery pipe through a hose. When the movable plate drives the die-cutting tool to move downwards so that the first spray head is separated from the cylindrical aluminum casting by a certain distance (this distance is greater than the outer diameter of the die-cutting tool), the annular cutting edge of the die-cutting tool cuts off the waste material at the upper edge of the cylindrical aluminum casting, and the second spray head sprays coolant for cooling.

[0027] During the cutting process, the second spray head plays an important role in cooling. Since a large amount of heat is generated during cutting, which may affect the tool life and the workpiece quality, the second spray head sprays coolant when the die-cutting tool is working, which can reduce the temperature of the cutting area, reduce tool wear, ensure the cutting quality, and prevent adverse effects on the workpiece caused by high temperature, ensuring the smooth progress of the entire processing process.

[0028] As a further optimized solution of the present invention, a connecting block is installed on a movable end of the transmission component away from the movable plate. A connecting plate is hingedly installed on the connecting block, and the free end of the connecting plate is fixed to the movable arm.

[0029] The clamping component has a plurality of clamping parts circumferentially and evenly distributed around the outer periphery of the lower end of the cylindrical aluminum casting, and the plurality of clamping parts are driven by a driving member to move synchronously closer to or away from the cylindrical aluminum casting. By switching the on-off state of the clamping component, the movable arm is synchronously turned up and down, and the turning angle is 0 - 90°.

[0030] The design of the connecting block and the connecting plate makes the connection between the movable arm and the transmission component more flexible. The driving member of the clamping component controls the opening and closing of the clamping parts. During loading and unloading, when the clamping parts release the cylindrical aluminum casting, the movable arm can be synchronously turned upwards, driving the cleaning component away from the workpiece, facilitating the operator to perform loading and unloading operations, improving work efficiency, and avoiding collisions between the cleaning component and the workpiece during loading and unloading.

[0031] As a further optimized solution of the present invention, the clamping assembly further includes a wedge block and a connecting rod. One end of the connecting rod is fixed to the outer side surface of the clamping portion, and the other end of the connecting rod is fixed to the wedge block. The wedge block is a wedge-shaped block, and the bottom of the movable arm has an inclined surface parallel to the top slope of the wedge block;

[0032] The driving member is preferably an electric push rod installed on the upper end surface of the turntable. The clamping portion is installed on the movable end of the electric push rod. When blanking the cylindrical aluminum casting, the electric push rod drives the clamping portion away from the cylindrical aluminum casting. The clamping portion drives the connecting rod and the wedge block to move outward synchronously, so that the top slope of the wedge block contacts the bottom inclined surface of the movable arm, and the movable arm rotates upward with the hinge axis of the connecting plate as the fulcrum, so that the movable arm drives the cleaning assembly away from the upper end of the cylindrical aluminum casting;

[0033] The cooperation of the wedge block and the connecting rod with the electric push rod realizes the ingenious linkage between the clamping assembly and the movable arm. During loading and unloading, the electric push rod drives the clamping portion away from the aluminum casting, drives the wedge block to move, the wedge block contacts the bottom inclined surface of the movable arm, and pushes the movable arm to flip, so that the cleaning assembly is away from the workpiece, which is convenient for operation.

[0034] As a further optimized solution of the present invention, transmission components, movable arms, and cleaning components are installed on both the left and right side walls of the frame. The number of clamping portions is two and they are symmetrically distributed left and right and form a clamping ring around. The number of electric push rods is two and they are symmetrically distributed on both sides of the upper end surface of the turntable. The two clamping portions are respectively installed on the movable ends of the two electric push rods. Two connecting rods are installed on the outer side surface of each clamping portion, and wedge blocks are installed on the two connecting rods and are symmetrically distributed with the axis of the electric push rod as the symmetry axis, so as to support the adjacent movable arms to rotate upward. The symmetric structure design on both sides of the frame ensures the stability of clamping the aluminum casting and improves the reliability of processing.

[0035] As a further optimized solution of the present invention, a positioning groove adapted to the lower end of the cylindrical aluminum casting is provided on the upper end surface of the turntable, which is convenient for the initial positioning of the cylindrical aluminum casting. A waste chip collection groove is also provided on the upper end surface of the turntable and is located outside the positioning groove. The waste chip collection groove is arc-shaped and symmetrically distributed left and right, and the ends of the two waste chip collection grooves are not connected, so as to centrally collect the cutting waste. A collection box that can be taken out outward is arranged inside the turntable. The lower end of the waste chip collection groove is communicated with the inner cavity of the turntable. The upper end of the collection box is open and is arranged below the waste chip collection groove.

[0036] The positioning groove on the turntable facilitates the quick positioning of the aluminum casting, and the waste chip collection groove and the collection box effectively collect the cutting waste, keep the working environment clean, facilitate the unified treatment of the waste, and improve the standardization and environmental protection of production.

[0037] The device for removing waste from the edge of aluminum die castings proposed by the present invention has the following beneficial effects:

[0038] (i) The device is provided with a cleaning component and is mounted on the upper edge of the cylindrical aluminum casting. When working, the turntable, the clamping component and the cylindrical aluminum casting are driven to rotate by the motor, and the cleaning component cleans the upper edge thereof, which can efficiently remove the mold release agent. When the subsequent die-cutting tool performs waste removal, the tool wear caused by carbonization of the mold release agent is greatly reduced, and the contamination of the workpiece by the carbonized mold release agent is avoided, thereby ensuring the processing quality and extending the service life of the tool;

[0039] (2) The movable plate is connected to the movable arm through a transmission assembly. When the movable plate drives the die-cutting tool to move downward, the second rack moves downward and meshes with the gear, driving the gear to rotate, thereby driving the first rack to move, so that the movable arm and the cleaning assembly are away from the cylindrical aluminum casting, accurately exposing the edge of the waste to be removed. This transmission structure is cleverly designed, ensuring the precise coordination of the cleaning assembly and the die-cutting tool at different working stages, thereby improving the accuracy and work efficiency of waste removal.

[0049] In the technical field of aluminum casting processing, the traditional method of removing edge waste from aluminum die-castings has problems such as tool wear and workpiece contamination caused by the carbonization of the mold release agent. The cutting device of the present invention effectively solves these problems through innovative design, and its specific implementation manners are as follows:

[0050] As Figure 1 shown, the device uses the frame 1 as the basic support structure. On the workbench surface of the frame 1, a turntable 9 is installed. The turntable 9 is equipped with a clamping assembly 2 for clamping the lower end of the cylindrical aluminum casting. A positioning groove adapted to the lower end of the cylindrical aluminum casting is provided on the upper end surface of the turntable 9, which facilitates the rapid positioning of the aluminum casting and ensures the accuracy of the machining position;

[0051] As Figure 1 and Figure 5 shown, a waste chip collecting groove 17 is also provided on the upper end surface of the turntable 9 and is located outside the positioning groove. The waste chip collecting groove 17 is arc-shaped and symmetrically distributed on the left and right, and the ends are not connected. Its lower end is connected to a collectible box that can be taken out from the inside of the turntable 9 for centrally collecting cutting waste and keeping the working environment clean;

[0052] As Figure 1 shown, on the side wall of the frame 1, a movable arm 3 is installed. A cleaning assembly 4 is installed at the free end of the movable arm 3. The cleaning assembly 4 is used to remove the mold release agent from the upper edge of the cylindrical aluminum casting to avoid its carbonization during subsequent cutting and having an adverse effect on the tool and the workpiece;

[0053] At the upper end of the frame 1, a liftable movable plate 5 is installed. The movable plate 5 is installed at the movable end of the elevator 8. At the lower end of the movable plate 5, a die-cutting tool 6 that is adapted to and centered with the upper end of the cylindrical aluminum casting is installed, which is responsible for cutting off the waste at the edge of the aluminum casting.

[0054] In addition, a transmission assembly 7 is also installed on the side wall of the frame 1. The two movable ends of the transmission assembly 7 are respectively connected to the movable arm 3 and the movable plate 5 to realize the linkage between the movable plate 5 and the movable arm 3, ensuring that the cleaning assembly 4 will not interfere with the cutting operation during cutting.

[0055] Specifically, as Figure 4 shown, the transmission assembly 7 is mainly composed of a gear 71, a first rack 72, and a second rack 73. The gear 71 is rotatably installed on the side wall of the frame 1 and is meshed with the first rack 72. One end of the first rack 72 is slidably assembled with the side wall of the frame 1, and the other end extends horizontally above the turntable 9 and is connected to the movable arm 3. One end of the second rack 73 is installed on the movable plate 5 and moves synchronously with the movable plate 5. The other end meshes with the gear 71 and drives the gear 71 to rotate when the movable plate 5 moves downward.

[0056] Furthermore, in order to ensure the smooth lifting of the movable plate 5 and the precise transmission of the rack, a longitudinal chute 11 is provided on the side wall of the frame 1. An end of the movable plate 5 is provided with a slider 10 that extends into the longitudinal chute 11 and is slidably assembled with the longitudinal chute 11. The second rack 73 is slidably arranged in the longitudinal chute 11, and its upper end is fixed to the bottom of the slider 10. A jack 12 that is opposite to and adapted to the lower end of the second rack 73 is provided on the bottom surface of the longitudinal chute 11. When the lower end of the second rack 73 moves downward synchronously with the movable plate 5, it will slide into the jack 12, restricting the displacement of the second rack 73 in the horizontal direction and ensuring that it always maintains the correct meshing position with the gear 71.

[0057] Furthermore, a slide rail 13 is installed on the bottom surface of the longitudinal chute 11. The first rack 72 is arranged between the gear 71 and the slide rail 13. A transverse chute 14 that is adapted to the slide rail 13 is provided at the lower end of the first rack 72, and its lower end is slidably assembled with the slide rail 13 through the transverse chute 14 to ensure the smoothness of the horizontal movement of the first rack 72.

[0058] As Figure 2 and Figure 3As shown in the figure, the cleaning assembly 4 includes a mounting base 41 and a cleaning brush roll 42. The mounting base 41 is mounted on the movable arm 3 and is located above the clamping assembly 2. One end of the cleaning brush roll 42 is rotatably mounted on the side of the mounting base 41 away from the movable arm 3 and is driven to rotate by an electric motor. The other end is placed on the upper edge of the upper end of the cylindrical aluminum casting. The mounting base 41 is hingedly mounted on the movable arm 3 and the inclination angle can be adjusted by fasteners to adapt to cylindrical aluminum castings of different specifications, ensuring that the cleaning brush roll 42 can be in good contact with the upper edge of the aluminum casting and improving the removal effect of the release agent;

[0059] Furthermore, the cleaning assembly 4 further includes a connecting arm 43 and a first spray head 44. One end of the connecting arm 43 is mounted on the mounting base 41, and the other end is mounted with the first spray head 44. The first spray head 44 is arranged obliquely above the cleaning brush roll 42 and is opposite to the upper edge of the cylindrical aluminum casting. The first spray head 44 sprays coolant when the cleaning brush roll 42 is working, facilitating the cleaning brush roll to clean and scrape the release agent on the surface of the aluminum casting, playing a role in cooling and preventing the release agent from carbonizing due to frictional heat generation;

[0060] Furthermore, guide rails are installed on both the front and rear sides of the upper end of the mounting base 41. One end of the connecting arm 43 away from the first spray head 44 is installed with a connecting frame 46. The connecting frame 46 is slidably assembled with the guide rail and locked by fasteners, enabling fine adjustment of the position of the first spray head 44. The first spray head 44 includes an outer housing and an inner spray head. The inner spray head is movably assembled in the outer housing through a universal ball, and the inclination angle is adjusted by bolts around the housing. The tail end is connected to the coolant delivery pipe through a hose to ensure that the coolant can be accurately sprayed on the part to be cleaned;

[0061] In addition, a second spray head 45 is also installed on the side of the mounting base 41 away from the movable arm 3. Its nozzle is opposite to the upper edge of the cylindrical aluminum casting, and the liquid inlet end is connected to the coolant delivery pipe through a hose. When the movable plate 5 drives the die-cutting tool 6 to move downward, after the first spray head 44 is separated from the cylindrical aluminum casting by a certain distance, and this distance is greater than the outer diameter of the die-cutting tool 6, the die-cutting tool 6 performs waste material cutting. At this time, the second spray head 45 sprays coolant for cooling, reducing tool wear and ensuring cutting quality.

[0062] As Figure 2 and Figure 5 shown in the figure, the clamping assembly 2 has a plurality of clamping parts 21 evenly distributed circumferentially around the outer periphery of the lower end of the cylindrical aluminum casting. In this embodiment, the number of clamping parts 21 is two and they are symmetrically distributed left and right and form a clamping ring. The plurality of clamping parts 21 are driven by a driving member to move synchronously closer to or away from the cylindrical aluminum casting. The driving member is preferably an electric push rod 24 installed on both sides of the upper end surface of the turntable 9. The two clamping parts 21 are respectively installed on the movable ends of the two electric push rods 24;

[0063] Further, the clamping assembly 2 further includes a wedge block 22 and a connecting rod 23. One end of the connecting rod 23 is fixed to the outer side surface of the clamping portion 21, and the other end is fixed to the wedge block 22. The bottom of the movable arm 3 has an inclined surface parallel to the top slope of the wedge block 22;

[0064] When discharging the cylindrical aluminum casting, the electric push rod 24 drives the clamping portion 21 away from the cylindrical aluminum casting. The clamping portion 21 drives the connecting rod 23 and the wedge block 22 to move outward synchronously. The top slope of the wedge block 22 contacts the bottom inclined surface of the movable arm 3, and the movable arm 3 rotates upward with the hinge axis of the connecting plate 16 as the fulcrum, driving the cleaning assembly 4 away from the upper end of the cylindrical aluminum casting, facilitating the operator to perform loading and unloading operations, improving work efficiency, and preventing the cleaning assembly 4 from colliding with the workpiece during the loading and unloading process.

[0065] Specifically, as Figure 2 and Figure 3 shown, a connecting block 15 is installed on an active end of the transmission assembly 7 away from the movable plate 5. A connecting plate 16 is hingedly installed on the connecting block 15, and the free end of the connecting plate 16 is fixed to the movable arm 3. This connection method makes the connection between the movable arm 3 and the transmission assembly 7 more flexible, ensuring smooth linkage between the clamping assembly 2 and the movable arm 3.

[0066] The working process of the device is as follows:

[0067] When performing the work of cutting off the waste material at the edge of the aluminum profile casting, first place the cylindrical aluminum casting on the positioning groove of the turntable 9, and drive the clamping portion 21 to approach the aluminum casting through the electric push rod 24 of the clamping assembly 2 to clamp and fix it;

[0068] Then, the motor drives the turntable 9, the clamping assembly 2, and the cylindrical aluminum casting to rotate. At this time, the cleaning brush roller 42 of the cleaning assembly 4 rotates at a high speed under the drive of the electric motor to clean the release agent at the upper edge of the aluminum casting, and the first nozzle 44 sprays coolant to assist in cleaning, improving the cleaning effect;

[0069] After the cleaning is completed, the elevator 8 drives the movable plate 5 and the die-cutting tool 6 to move downward. When the movable plate 5 moves downward, it drives the second rack 73 to move downward synchronously. The second rack 73 meshes with the gear 71, causing the gear 71 to rotate, and then driving the first rack 72 to move horizontally. The first rack 72 drives the movable arm 3 and the cleaning assembly 4 away from the cylindrical aluminum casting, exposing the edge where the waste material needs to be cut off. The die-cutting tool 6 continues to move downward to cut off the waste material at the edge of the aluminum casting, and at the same time, the second nozzle 45 sprays coolant for cooling;

[0070] After the waste removal is completed, the lift 8 drives the movable plate 5 and the die-cutting tool 6 to rise and reset. The electric push rod 24 drives the clamping part 21 away from the cylindrical aluminum casting. The clamping part 21 drives the movable arm 3 to turn upward through the connecting rod 23 and the wedge block 22, and the cleaning assembly 4 moves away from the aluminum casting, facilitating the operator to take out the processed aluminum casting and place a new aluminum casting to be processed for the next round of processing. During the whole processing process, the waste generated by cutting will fall into the waste chip collection tank 17 on the turntable 9 and enter the collection box through the lower end of the collection tank for subsequent unified treatment;

[0071] It should be noted that the specific dimensions of the components of this device can be obtained through calculation and experiment, so they will not be elaborated here.

[0072] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
