Description

Technical Field

[0001] This utility model relates to the technical field of sawing equipment, specifically a sawing machine that facilitates chip removal and cutting. Background Technology

[0002] During the sawing process, whether wet or dry cutting, a large amount of metal chips are generated. Existing saws are usually equipped with only simple chip removal troughs or manual cleaning methods, which have low chip removal efficiency. Chips tend to accumulate on the worktable surface, which not only affects the positioning accuracy of raw materials and leads to increased cutting errors, but may also enter the equipment's transmission components, causing wear and tear and shortening the equipment's service life.

[0003] However, existing saws that facilitate chip removal and cutting still have some drawbacks in actual use: For saws that use wet cutting, although some equipment is equipped with a coolant recovery structure, the filter components in the existing recovery structure are mostly fixed and cannot be quickly disassembled according to the switching of processing methods. This makes the filter components redundant in dry cutting scenarios, which not only occupies the chip removal channel space and affects the chip removal speed during dry cutting, but also reduces the adaptability of the equipment to different processing scenarios. As a result, it is difficult for a single saw to meet the high-efficiency processing requirements of both wet and dry cutting at the same time, and the equipment utilization rate is low.

[0004] To address these issues, we designed a saw that facilitates chip removal and cutting. Utility Model Content

[0005] The purpose of this invention is to provide a saw that facilitates chip removal and cutting, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a sawing machine for easy chip removal and cutting, including a worktable, a cutting device fixedly installed on the top surface of the worktable, and support columns fixedly installed at the four corners of the top surface of the worktable.

The fan can reciprocate in the horizontal direction. A chip removal groove is opened on the worktable. A collection box is installed below the chip removal groove. A chip removal pipe is fixedly installed on the top of the collection box. A flexible hose is connected between the bottom of the chip removal groove and the chip removal pipe. A filter assembly is installed inside the chip removal pipe. The filter assembly includes a filter screen for separating chips and coolant.

[0007] Furthermore, the filter assembly also includes a fixing frame, which is fixedly installed on the inner side wall of the chip discharge pipe. A mounting bracket is detachably connected inside the fixing frame, and the filter screen is fixedly installed inside the mounting bracket.

[0010] Furthermore, a drive motor is provided on one side of the ball screw pair, and the drive end of the drive motor passes laterally through the support column and is fixedly connected to the shaft of the ball screw pair via a coupling.

[0011] Furthermore, the cross-section of the chip removal groove is set to be trapezoidal, with its shape being wider at the top and narrower at the bottom.

The ball screw axis of the ball screw pair is aligned with the center of the moving seat to avoid uneven load. A transparent protective plate is fixedly installed between adjacent support columns.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model provides a technical solution: a sawing machine for easy chip removal and cutting, including a worktable 1, which serves as the basic load-bearing structure of the sawing machine and provides installation support for various components. A cutting device 2 (i.e., the sawing machine) is fixedly installed on the top surface of the worktable 1, which is used to cut raw materials; support columns 3 are fixedly installed at the four corners of the top surface of the worktable 1, which support auxiliary components 4; the auxiliary components 4 include a fan 5 for assisting the flow of the mixture of chips and coolant, which can reciprocate in the horizontal direction to assist in guiding the mixture in different areas of the worktable 1; a chip removal groove 6 is provided on the worktable 1, which is used to collect the mixture of chips and coolant (under its own weight, the aforementioned mixture naturally flows along the chip removal groove). The downward movement of the inclined plane 6, combined with the blowing function of the fan 5, increases the total downward force and fluidity. A collection box 7 is provided below the chip discharge trough 6. The collection box 7 is used to collect the separated coolant and debris. A chip discharge pipe 8 is fixedly installed on the top of the collection box 7. A flexible hose is provided between the bottom of the chip discharge trough 6 and the chip discharge pipe 8. The flexible hose can adapt to the positional relationship between the chip discharge trough 6 and the chip discharge pipe 8 to facilitate the transport of the mixture. A filter assembly 9 is provided inside the chip discharge pipe 8. The filter assembly 9 includes a filter screen 12 for separating debris and coolant. The filter screen 12 realizes liquid-solid separation of the mixture.

[0022] In practice, when raw materials are conveyed to the cutting device 2 by the conveying device or manually placed at the cutting device 2 for cutting, a large amount of debris is generated. Simultaneously, coolant is used to cool the cutting area during processing, forming a mixture of debris and coolant. The blower 5 is activated, and the airflow generated by the blower 5 assists the mixture on the worktable 1 to flow towards the bottom of the chip removal trough 6. Under the collection effect of the chip removal trough 6, the mixture enters the chip removal pipe 8 through a hose, and then flows into the collection box 7. When it flows through the filter assembly 9 in the chip removal pipe 8, the filter screen 12 intercepts the debris, while the coolant flows back into the collection box 7 through the filter screen 12, achieving the recycling of the coolant.

[0023] See Figure 3 The filter assembly 9 also includes a fixing frame 10, which is fixedly installed on the inner wall of the chip removal pipe 8 to provide a mounting base for the mounting bracket 11. The bottom end of the hose is fitted onto the outer wall of the chip removal pipe 8 (e.g., through a friction connection or through a threaded connector) to make way for the fixing frame 10. The mounting bracket 11 is detachably connected inside the fixing frame 10, and the filter screen 12 is fixedly installed inside the mounting bracket 11. By removing the mounting bracket 11, the debris intercepted on the filter screen 12 can be cleaned or the filter screen 12 can be replaced.

[0024] The length of the chip removal pipe 8 is less than the length of the hose. The filter assembly 9 is installed inside the chip removal pipe 8 rather than inside the flexible tube because: the flexible tube has a side-wall sealed and top-and-bottom open structure, so the filter screen 12 can only be inserted (i.e., installed) and removed (i.e., removed) from the top or bottom opening of the flexible tube. The flexible tube has a long length and a small diameter, making it difficult for the user's palm and arm to reach into the flexible tube to operate the filter screen 12 / mounting bracket 11 (the operation of the filter screen 12 / mounting bracket 11, including removal and installation, cannot simultaneously achieve convenient installation and removal, regardless of whether the filter assembly 9 is located at the top, bottom, or middle of the flexible tube); while the chip removal pipe 8 has a shallow inner depth (depth within 3 cm, diameter not less than 5 cm), the user's fingers can reach into the chip removal pipe 8 to pinch the upper pull ring, thereby lifting the filter screen 12 and mounting bracket 11 upwards (until it is pulled out of the chip removal pipe 8), or the user can directly press the filter screen 12 / mounting bracket 11 downwards with their fingers to make the filter screen 12 / mounting bracket 11 engage with the fixing frame 10.

[0025] In practice, when a lot of debris accumulates on the filter screen 12 and affects the filtration effect, or when the filter screen 12 needs to be replaced, the mounting bracket 11 can be removed from the fixed frame 10, the debris can be cleaned or the filter screen 12 can be replaced, and then the mounting bracket 11 can be put back into the fixed frame 10. The operation is convenient and can ensure the continuous and effective operation of the filter assembly 9.

[0026] See Figure 4 The inner wall of the fixed frame 10 is provided with a snap-fit ​​groove 13, and the outer wall of the mounting bracket 11 is fixedly connected with a snap-fit ​​block 14. The snap-fit ​​block 14 cooperates with the snap-fit ​​groove 13 to achieve the initial positioning of the mounting bracket 11 and the fixed frame 10. The inner wall of the snap-fit ​​groove 13 is provided with a sliding groove 15. A limit block 16 is horizontally slidably arranged in the sliding groove 15. The limit block 16 is elastically connected to the inner wall of the sliding groove 15 through a return spring 17. The limit block 16 cooperates with the snap-fit ​​block 14 to further fix the mounting bracket 11 and prevent it from loosening during use.

[0027] In practice, when installing the mounting bracket 11, simply align the snap-fit ​​block 14 on the mounting bracket 11 with the snap-fit ​​groove 13 of the fixed frame 10 and push it downwards. The snap-fit ​​block 14 will push the limit block 16 into the slide groove 15, and the return spring 17 will be compressed. When the snap-fit ​​block 14 is fully inserted into the snap-fit ​​groove 13, the return spring 17 will restore its deformation, push the limit block 16 to reset, and snap-fit ​​with the snap-fit ​​block 14, thus completing the fixing of the mounting bracket 11.

[0028] See Figure 1 and Figure 2The auxiliary component 4 also includes a ball screw pair 19, which includes a screw and a nut that cooperate with each other. A crossbeam 18 is fixedly arranged between two opposing support columns 3. The ball screw pair 19 is arranged between the two opposing crossbeams 18. The ball nut of the ball screw pair 19 is fixedly connected to a movable seat 22. When the screw of the ball screw pair 19 rotates, it can drive the movable seat 22 to move laterally. In addition, a slide rod 20 is fixedly arranged between two support columns 3. A slider 21 is slidably connected to the outer arc wall of the slide rod 20. The two ends of the movable seat 22 are fixedly connected to the two sliders 21 respectively. The sliders 21 cooperate with the slide rod 20 to provide guidance and support for the movement of the movable seat 22. The fan 5 is fixedly installed on the lower surface of the movable seat 22 and moves laterally with the movable seat 22.

[0029] The top surfaces of the two crossbars 18 are respectively fixed with bearing seats by bolts. The ball screw pair 19 has a smooth shaft surface at both ends of the screw, and the smooth shaft surface is set coaxially with the screw. The two smooth shaft surfaces are respectively inserted into the bearing seats, and bearings are installed between the smooth shaft surface and the corresponding bearing seats, thereby supporting the screw and reducing the rotational friction of the screw.

[0030] In practice, the start-up drive assembly drives the screw of the ball screw pair 19 to rotate. The ball nut of the ball screw pair 19 will drive the moving seat 22 to move laterally along the axis of the ball screw pair 19. When the moving seat 22 moves, it will drive the sliders 21 at both ends to slide along the slide rod 20, thereby driving the fan 5 to move laterally, so that the fan 5 can blow air to multiple positions in the cutting area, expand the auxiliary flow range, and improve the chip removal effect.

[0031] See Figure 1 A drive motor 23 is installed on one side of the ball screw assembly 19. The drive end of the drive motor 23 passes laterally through the support column 3 via a coupling and is fixedly connected to the axis of the ball screw assembly 19 (e.g., via bolts and keys). The drive motor 23 provides power for the rotation of the ball screw assembly 19. The housing of the drive motor 23 is fixedly connected to the outer wall of the cross frame 18 via bolts. The drive motor 23 is a controllable motor (e.g., a servo motor or a stepper motor). An external controller (e.g., a computer or a PLC programmable logic controller) inputs electrical signals to the controllable motor, which can control the speed, number of revolutions per cycle, and start / stop timing of the controllable motor. The drive motor 23 and the fan 5 are respectively connected to the external power supply via wires. The drive motor 23 is connected to the external controller via wires and signal lines, and the fan 5 is connected to the external controller via wires and signal lines.

[0032] In practice, when the position of the fan 5 needs to be adjusted, the drive motor 23 is started. The drive end of the drive motor 23 drives the screw of the ball screw pair 19 to rotate through the coupling. Then, through the cooperation of the ball screw pair 19 and the moving seat 22, the fan 5 can be moved laterally. The drive motor 23 can be controlled to move the fan 5 back and forth by controlling forward and reverse rotation, which is flexible in operation.

[0033] See Figure 1 The cross-section of the chip removal groove 6 is set as a trapezoid, with the shape being wider at the top and narrower at the bottom. This structure can more effectively collect the mixture of chips and coolant on the worktable 1, reduce the residue of the mixture on the worktable 1, and improve chip removal efficiency.

[0034] In practice, the mixture of chips and coolant generated during the cutting process will be scattered on the top surface of the workbench 1. Due to the trapezoidal structure of the chip removal groove 6, which is wider at the top and narrower at the bottom, the mixture will converge towards the opening of the chip removal groove 6 under the assistance of gravity and the airflow of the fan 5, and then enter the hose through the outlet at the bottom of the chip removal groove 6, and finally be transported to the chip removal pipe 8.

[0035] See Figure 4 The upper and lower sides of the end of the limiting block 16 near the snap-fit ​​block 14 are set as inclined surfaces, and the upper and lower sides of the end of the snap-fit ​​block 14 near the limiting block 16 are set as inclined surfaces. The inclined surface structure can reduce the frictional resistance between the snap-fit ​​block 14 and the limiting block 16 during installation, making it easier for the snap-fit ​​block 14 to push the limiting block 16 to move and reducing the installation difficulty.

[0036] In practice, when the mounting bracket 11 pushes the snap-fit ​​block 14 into the snap-fit ​​groove 13, the inclined surface of the snap-fit ​​block 14 contacts the inclined surface of the limiting block 16. As the thrust increases, the two inclined surfaces interact with each other, and the limiting block 16 will automatically slide into the slide groove 15 without any additional operation, thus simplifying the installation steps.

[0037] See Figure 2 The upper end of the chip removal pipe 8 is threaded to the lower end of the hose. The threaded connection facilitates the disassembly and installation of the chip removal pipe 8 and the hose. When it is necessary to clean or maintain the inside of the chip removal pipe 8, the chip removal pipe 8 can be unscrewed, which is convenient.

[0038] In practice, when the chip removal pipe 8 becomes clogged or the filter assembly 9 needs to be repaired, the chip removal pipe 8 can be rotated to separate it from the hose. After cleaning or repair, the chip removal pipe 8 and the hose can be reconnected and fixed by threads to ensure the sealing between the chip removal pipe 8 and the hose and prevent the mixture from leaking.

[0039] See Figures 1-4Both the ball screw assembly 19 and the slide bar 20 are fitted with telescopic sleeves. The telescopic sleeves prevent debris, coolant, and other contaminants generated during the cutting process from entering the ball screw assembly 19 and the slide bar 21, thus avoiding affecting their normal operation and extending their service life. The telescopic sleeves are made of plastic corrugated tubing, and the total length is extended by partial bending. The ball screw axis of the ball screw assembly 19 is aligned with the center of the moving seat 22 to avoid uneven loading, ensure the stability of the moving seat 22 during movement, and prevent the fan 5 from shaking. Transparent protective plates are fixedly installed between adjacent support columns 3. The transparent protective plates are made of tempered glass. Tempered glass has high strength and can play a protective role, preventing debris from flying and injuring people during the cutting process. At the same time, the transparent design makes it easy for operators to observe the processing situation. The top of the mounting frame 11 is provided with an upper pull ring. The upper pull ring provides a force point for disassembling the mounting frame 11, making it easy for operators to pull the mounting frame 11 upwards to separate the locking block 14 from the limiting block 16 and complete the disassembly of the mounting frame 11.

[0040] Regarding the telescopic sleeve fitted around the outer periphery of the ball screw assembly 19: There are two telescopic sleeves, which are respectively located on both sides of the nut of the ball screw assembly 19. One end of the telescopic sleeve is sealed and fixedly connected to the end face of the nut of the ball screw assembly 19 (e.g., by bonding), and the other end is sealed and fixedly connected to the side wall of the bearing seat (e.g., by bonding).

[0041] Regarding the telescopic sleeves fitted around the outer periphery of the slide bar 20: two such telescopic sleeves are fitted around the outer periphery of a single slide bar 20; a telescopic sleeve is provided on each side of the slider 21; one end of the telescopic sleeve is sealed and fixedly connected to the end face of the slider 21 (e.g., by adhesive bonding), and the other end is sealed and fixedly connected to the side wall of the support column 3 and / or the side wall of the cross frame 18 (e.g., by adhesive bonding).

[0042] In practice, during the cutting process, the telescopic sleeve always covers the ball screw assembly 19 and the slide bar 20, preventing the intrusion of debris and coolant. Operators can observe the cutting status and chip removal of the raw materials through the transparent protective plate, and promptly identify and address any problems. When it is necessary to disassemble the mounting bracket 11, the operator can grasp the upper pull ring and pull it upwards to make the locking block 14 push the limit block 16 to compress the reset spring 17 and enter the slide groove 15. Continuing to pull will remove the mounting bracket 11 from the fixed frame 10.

[0043] Working principle: When in use, the raw material is conveyed to the cutting device 2 by the conveying device for cutting. During the cutting process, a large amount of debris will be generated. The fan 5 starts, and the coolant and debris on the auxiliary workbench 1 are collected by the chip discharge trough 6 and introduced into the collection box 7 through the hose and chip discharge pipe 8. After passing through the filter assembly 9, liquid-solid separation is achieved. The coolant flows back to the collection box 7 for recycling, while the debris is retained in the filter assembly 9.

[0044] During installation, simply push the mounting bracket 11 downwards, and the snap-fit ​​block 14 will push the limit block 16 into the slide groove 15. The return spring 17 will be compressed. Once the snap-fit ​​block 14 enters the snap-fit ​​groove 13, the installation is complete. The filter assembly 9 is suitable for wet cutting, but in dry cutting environments, the filter assembly 9 becomes a redundant configuration. Depending on different processing requirements, such as switching from wet cutting to dry cutting, the filter assembly 9 can be quickly disassembled, enabling a single saw to adapt to various processing scenarios and improve equipment utilization.

[0045] The start-up drive motor 23 drives the ball screw pair 19 to rotate, which in turn drives the fan 5 to move laterally and blow air at multiple locations in the cutting area. In addition, as the ball screw pair 19 drives the moving seat 22 to move, the slider 21 also slides, making the movement of the fan 5 more stable.

[0046] Since the filter screen 12 is located below the hose, debris will accumulate above the filter screen 12 and in the lower part of the hose's inner cavity. Therefore, the user needs to first pinch the bottom of the hose horizontally with their hand, and then disconnect the connection between the chip removal pipe 8 and the hose (to avoid the problem of debris falling out of the hose at the moment of disconnection). After that, the user moves the bottom of the hose to the side of the transfer container (such as a storage box with an open top, temporarily placed on the processing workshop floor next to the collection box 7) and then releases their hand, allowing the debris in the hose's inner cavity to fall into the transfer container (during this process, if necessary, cleaning fluid can be poured into the chip removal trough 6 to flush out the remaining debris in the hose's inner cavity). After that, the user uses a spoon to scoop out the remaining debris in the inner cavity of the chip removal pipe 8 and pour it into the transfer container. After that, the user takes out the mounting bracket 11 and the filter screen 12, pours out, filters, and stores the coolant in the collection box 7 for later reuse.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
