Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, in particular to a high-precision laser cutting machine for metal parts. Background Art

[0002] Metal parts refer to a collection of metal blocks, bars, and tubes of various sizes and shapes made from metal materials. Metal parts are generally processed through mechanical processing, which refers to the process of changing the dimensions or properties of a workpiece using a mechanical device. Machining can be categorized into cutting and press working based on the processing method. Machining metal parts requires specialized cutting equipment. Laser cutting machines are a commonly used device for cutting metal parts.

[0003] Specifically, the laser cutting machine is equipped with a high-power laser, and the laser beam can accurately control the shape and size of the cut metal parts, thereby achieving an efficient and precise cutting process. Metal laser cutting robots are widely used in the fields of metal processing and manufacturing. They can be used to cut metal plates, metal pipes, etc. of various thicknesses and types, improving production efficiency and ensuring cutting quality.

[0004] Laser cutting equipment in the prior art, such as the Chinese patent with authorization announcement number CN215238662U, entitled "A laser cutting mechanism for high-precision metal parts processing", discloses a laser cutting mechanism for high-precision metal parts processing, comprising a base plate, the bottom of which is provided with support legs, the bottom of which is sleeved with support pads, support rods provided on both sides above the base plate, the end of the support rod away from the base plate is fixedly connected to a top plate, fixed plates are installed on both sides of the bottom of the top plate, the inner side wall of the fixed plate is connected to a screw, a slider is slidably connected to the screw, a laser cutter is installed at the bottom of the slider, and a processing table is installed at the center above the base plate. In the above patent, the metal parts are clamped and fixed to the surface of the processing table by clamping pads to prevent the metal parts from moving during the cutting process, thereby improving the cutting accuracy.

[0005] Another example is the Chinese patent with the authorization announcement number CN217253696U, entitled "A metal part fixing fixture for laser cutting machines". The above patent discloses a metal part fixing fixture for laser cutting machines, which relates to the field of laser cutting machines and includes a base and a slide. Cabinet doors are symmetrically hinged on both sides of the front of the base. Support legs are fixedly connected to the four sides of the top of the base. The top of the base is fixedly connected to a workbench. The top of the workbench is fixedly connected to a box. The top of the left side of the box is fixedly connected to a drive motor. The above patent can facilitate users to quickly fix metal parts of different thicknesses. By using a fixed splint in conjunction with a roller, it can facilitate pushing heavier metal parts in and out of the top of the fixed splint.

[0006] The existing technologies, such as the above-mentioned patents, can meet the cutting needs of metal parts to a certain extent. However, it is known that in order to improve the quality of laser cutting, the existing technology generally chooses to use a fixing component to fix the workpiece. After the laser cutting is completed, the fixing component must first be unlocked to realize the transportation of the workpiece. In addition, the laser uses high energy density to rapidly heat the material to the melting point or vaporization point. If the energy is not enough to completely vaporize the material, the melted part may not be completely blown away by the auxiliary gas, and solidify into waste slag after cooling. And part of the waste slag will remain on the workpiece, and the existing technology can only remove the workpiece from the cutting mechanism and then use the slag removal mechanism alone to remove the slag from the workpiece. However, in order to improve the slag removal efficiency during the slag removal process, it is still necessary to fix the workpiece again and then perform the slag removal operation. Therefore, after the slag removal operation is completed, it is necessary to unlock the workpiece after the slag removal operation is completed. This operation process is cumbersome.

[0007] It can be seen that after using a laser cutting device on a device to fix the workpiece with a fixing component and complete the cutting operation on the workpiece during the process of cutting the workpiece, how to passively fix the workpiece again through the fixing component and remove the slag from the workpiece during the reset process of the laser cutting equipment is a technical problem that needs to be solved urgently. Summary of the Invention

[0008] The purpose of the present invention is to provide a high-precision laser cutting machine for metal parts to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a high-precision laser cutting machine for metal parts, comprising a work frame and a first conveying member and a second conveying member installed on both sides of the work frame for conveying workpieces, a cutting part being slidably connected to the work frame, and a servo motor for driving the cutting part to slide is provided on the work frame; clamping parts are slidably connected to both sides of the work frame, and a pressure mechanism is provided on the work frame for driving the clamping parts on both sides to move toward each other through a linkage mechanism, and the servo motor rotating shaft is connected to the pressure mechanism; a slag removal mechanism for removing slag from the cut workpiece is slidably connected to the work frame, and the slag removal mechanism is intermittently transmitted to the pressure mechanism.

[0011] Furthermore, the pressure mechanism includes a first screw rod rotatably connected to the working frame, the servo motor rotating shaft is coaxially connected to the first screw rod, and a pressure block is slidably connected to the working frame, the pressure block is threadedly connected to the first screw rod, and the pressure block is slidably connected to the pressure plate through a guide portion.

[0012] Furthermore, the slag removal mechanism includes a mounting plate slidably connected to the working frame, and a cleaning unit is provided on the mounting plate; a reciprocating screw is rotatably connected to the working frame, and the reciprocating screw is threadedly connected to the mounting plate through a threaded sleeve.

[0013] Furthermore, a first connecting rod and a second connecting rod are rotatably connected to the workbench, the second connecting rod and the reciprocating screw rod are connected via a first synchronous member, the first screw rod and the first connecting rod are connected via a second synchronous member, and a one-way transmission member is provided between the first connecting rod and the second connecting rod.

[0014] Furthermore, the pressure block is slidably connected to an adjustment block through a positioning portion, and a locking member is provided between the adjustment block and the pressure block to lock the state of the adjustment block and the pressure block; the locking member includes a locking rod slidably connected to the inside of the pressure block, the locking rod is inserted into the adjustment block through a locking groove, and a locking spring is also provided between the locking rod and the pressure block; the adjustment block is also vertically slidably connected to a clamping member for limiting the locking rod.

[0015] Furthermore, the clamping member includes a clamping rod slidably connected to the pressure block, the clamping rod is clamped with the locking rod through a clamping groove, and a clamping spring is provided between the clamping rod and the pressure block to limit the state of the clamping rod.

[0016] Furthermore, the working frame is also provided with an unlocking portion for driving the clamping rod to slide out from the inside of the clamping groove; the unlocking portion includes a mounting block installed on the working frame, and an unlocking block is slidably connected to the mounting block through an elastic portion; a connecting block is fixedly connected to the clamping rod, and an unlocking groove adapted to the unlocking block is provided on the connecting block.

[0017] Furthermore, a first abutting surface and a second abutting surface are provided on the unlocking block, and the first abutting surface and the second abutting surface are respectively in intermittent contact with the connecting block.

[0018] Furthermore, the cleaning unit includes vertical cleaning brushes slidably connected to both sides of the mounting plate, and each vertical cleaning brush is slidably connected to a transverse cleaning brush.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: during use of the high-precision laser cutting machine for metal parts, when the servo motor shaft rotates forward, the pressure mechanism drives the clamping parts on both sides to approach each other through the linkage mechanism to fix the workpiece, and drives the cutting part to cut the workpiece. That is, in actual use, the workpiece is first installed on the first conveyor member, and is transported to a predetermined position by the first conveyor member. Then, as in the above-mentioned operation process, the servo motor shaft rotates forward, and the two clamping parts are driven to approach each other through the cooperation of the pressure mechanism and the linkage mechanism to fix the workpiece. And in the stroke in which the clamping part fixes the workpiece, at this moment, the cutting part is driven to slide on the workbench through the cooperation of the second screw rod and the trapezoidal slider, and the cutting operation of the workpiece is completed by clamping, which not only improves the stability of the workpiece during the cutting operation, but also improves the cutting quality of the workpiece.

[0020] When the servo motor's rotating shaft reverses, the pressure mechanism drives the two clamping parts to fix the workpiece again during the stroke, and the slag removal mechanism performs a slag removal operation on the workpiece. Specifically, after the workpiece cutting is completed, that is, after the cutting part reaches a predetermined position, it is necessary to drive the servo motor to reverse. When the servo motor's rotating shaft reverses, it will drive the cutting part to reset. And during the stroke of the cutting part resetting, the pressure mechanism will drive the two clamping parts to fix the workpiece again. At this moment, what can be achieved is that the clamping parts can fix the workpiece raw material and the cut workpiece separately, and during the stroke of using the pressure mechanism to drive the clamping parts to fix the workpiece raw material and the cut workpiece separately, the slag removal mechanism is used to perform a slag removal operation on the workpiece raw material fixed by the clamping parts and the cut workpiece. At this moment, there is no need to remove the cut workpiece from the cutting machine separately for slag removal. In addition, the slag removal mechanism is intermittently connected to the pressure mechanism, so that the servo motor can be used to drive the slag removal mechanism to slide on the workbench during the stroke of the cutting part resetting, so that the workpiece can be slag removed.

[0021] During these operations, no additional power sources, such as motors and air pumps, are required, directly reducing energy consumption. Furthermore, the slag removal process is completed synchronously with the reset stroke, eliminating the time wasted in separate operations and improving overall operational efficiency. Furthermore, the mechanical structure eliminates the need for complex control systems and sensors, significantly reducing hardware costs. Slag removal strictly follows the reset rhythm of the cutting head, ensuring immediate slag removal after each cut to prevent residue from affecting subsequent machining accuracy. Slag and oxide layers are also promptly removed from the cut edge, minimizing secondary contamination, improving the surface finish of the workpiece, and reducing thermal stress damage to the metal material.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] See also Figures 1-20 The present invention provides a technical solution: a high-precision laser cutting machine for metal parts, comprising a work frame 1 and a first conveying member 2 and a second conveying member 3 installed on both sides of the work frame 1 for conveying a workpiece 5, a cutting part 4 being slidably connected to the work frame 1, and a servo motor 7 for driving the cutting part 4 to slide is provided on the work frame 1; clamping parts 6 are slidably connected to both sides of the work frame 1, and a pressure mechanism 9 is provided on the work frame 1 for driving the clamping parts 6 on both sides to move toward each other through a linkage mechanism 8, and the rotating shaft of the servo motor 7 is connected to the pressure mechanism 9; a slag removal mechanism 10 for removing slag from the cut workpiece 5 is slidably connected to the work frame 1, and the slag removal mechanism 10 is intermittently transmitted to the pressure mechanism 9.

[0046] Specifically, the high-precision laser cutting machine for metal parts includes a workbench 1 and a first conveying member 2 and a second conveying member 3 installed on both sides of the workbench 1 for conveying a workpiece 5. Specifically, the first conveying member 2 and the second conveying member 3 are both existing technologies and are used for conveying the workpiece 5. The first conveying member 2 conveys the raw material of the workpiece 5 that has not been cut. When in use, the raw material of the workpiece 5 is conveyed to a predetermined work station by the first conveying member 2 for cutting. During the cutting process, a part of the raw material of the workpiece 5 is already on the second conveying member 3. Therefore, after the cutting operation is completed, the second conveying member 3 can convey the cut workpiece 5 when it is started, thereby realizing the conveyance of the workpiece 5 and meeting the work needs. The first conveying member 2 and the second conveying member 3 are driven by different drive sources respectively and controlled by a programmable logic controller (PLC), specifically controlling the opening and closing and running speed of the first conveying member 2 and the second conveying member 3.

[0047] Specifically, a cutting unit 4 is slidably connected to the work frame 1. This cutting unit 4 is conventional and includes a laser cutting assembly. Furthermore, a trapezoidal slider is slidably connected to the work frame 1, and the laser cutting assembly is mounted on the trapezoidal slider. Furthermore, a servo motor 7 is provided on the work frame 1 for driving the cutting unit 4 to slide. Specifically, a second screw is rotatably connected to the work frame 1. The trapezoidal slider is threadedly connected to the second screw via a threaded hole. A pulley transmission is provided between the second screw and the rotating shaft of the servo motor 7, which can drive the second screw to rotate, thereby enabling the trapezoidal slider to drive the cutting unit 4 to slide and perform a cutting operation on the workpiece 5.

[0048] The work frame 1 is provided with a clamping portion 6 slidably connected on both sides. The clamping portion 6 can clamp and fix the workpiece 5, thereby improving the stability of the workpiece 5 during the cutting operation, thereby improving the cutting quality of the workpiece 5 and achieving better performance. The work frame 1 is also provided with a pressure mechanism 9 that drives the clamping portions 6 on both sides to move toward each other through a linkage mechanism 8. Specifically, the clamping portions 6 on both sides are connected by the linkage mechanism 8, which can better clamp and fix the workpiece 5. The servo motor 7 rotation shaft is connected to the pressure mechanism 9. At this time, when in use, when the servo motor 7 rotation shaft rotates, the pressure mechanism 9 and the linkage mechanism 8 cooperate to drive the two clamping portions 6 to move closer together, thereby fixing the workpiece 5. Moreover, during the travel of the clamping portion 6 fixing the workpiece 5, the cutting portion 4 is driven to slide on the work frame 1 through the cooperation of the second screw and the trapezoidal slider, thereby clamping and completing the cutting operation of the workpiece 5. This not only improves the stability of the workpiece 5 during the cutting operation, but also improves the cutting quality of the workpiece 5. Moreover, during the above working process, there is no need to use a separate power source to drive the clamping part 6 to fix the workpiece 5. Instead, the clamping part 6 is passively fixed to the workpiece 5 during the movement of the cutting part 4. This not only saves energy but also saves costs, and is suitable for wide promotion and use.

[0049] A slag removal mechanism 10 is slidably connected to the workbench 1 for removing slag from the workpiece 5 after cutting. The slag removal operation can be performed on the workpiece 5 after cutting, and there is no need to remove the cut workpiece 5 from the cutting machine separately and then perform additional slag removal operations. The slag removal mechanism 10 is intermittently connected to the pressure mechanism 9, so that the servo motor 7 can be used to drive the cutting part 4 to reset and drive the slag removal mechanism 10 to slide on the workbench 1 through the pressure mechanism 9, so that the workpiece 5 can be removed from the workbench 1.

[0050] More specifically, the cutting machine can be divided into two different working states according to the rotation direction of the rotating shaft of the servo motor 7:

[0051] First station: When the servo motor 7 rotates in the forward direction, the pressure mechanism 9 drives the clamping parts 6 on both sides to approach each other through the linkage mechanism 8 to fix the workpiece 5, and drives the cutting part 4 to cut the workpiece 5. That is, in actual use, the workpiece 5 is first installed on the first conveyor 2, and is transported to a predetermined position by the first conveyor 2. Then, as in the above-mentioned operation process, the servo motor 7 rotates in the forward direction, and the two clamping parts 6 are driven to approach each other through the cooperation of the pressure mechanism 9 and the linkage mechanism 8 to fix the workpiece 5. And in the process of the clamping part 6 fixing the workpiece 5, at this moment, the cutting part 4 is driven to slide on the workbench 1 through the cooperation of the second screw and the trapezoidal slider to complete the cutting operation of the workpiece 5, which can not only improve the stability of the workpiece 5 during the cutting operation, but also improve the cutting quality of the workpiece 5. Moreover, since the slag removal mechanism 10 is intermittently connected to the pressure mechanism 9, when the servo motor 7 rotating shaft rotates forward, it will not drive the slag removal mechanism 10 to move. The slag removal mechanism 10 can only be driven to move when the servo motor 7 rotating shaft rotates reversely.

[0052] During the above operation, after the servo motor 7 drives the cutting unit 4 to complete the cutting operation on the workpiece 5, when the servo motor 7 shaft continues to rotate, it can drive the pressure mechanism 9 to continue to slide until the pressure mechanism 9 is disengaged from the linkage mechanism 8. At this time, the clamping units 6 on both sides will reset and unlock the workpiece 5. At this time, after the clamping units 6 unlock the workpiece 5, the second conveying member 3 is started to convey the cut workpiece 5, so that a slag removal space is formed between the cut workpiece 5 and the raw material of the workpiece 5.

[0053] The second workstation: When the servo motor 7 rotates in reverse, the pressure mechanism 9 drives the two clamping parts 6 to fix the workpiece 5 again, and the slag removal mechanism 10 performs slag removal on the workpiece 5. Specifically, after the cutting of the workpiece 5 is completed, that is, after the cutting part 4 reaches the predetermined position, it is necessary to drive the servo motor 7 to reverse. When the servo motor 7 rotates in reverse, it will drive the cutting part 4 to reset. And in the process of resetting the cutting part 4, the pressure mechanism 9 will drive the two clamping parts 6 to fix the workpiece 5 again. At this moment, what can be achieved is that the clamping part 6 can fix the workpiece 5 raw material and the cut workpiece 5 separately, and in the process of using the pressure mechanism 9 to drive the clamping part 6 to fix the workpiece 5 raw material and the cut workpiece 5 separately, the slag removal mechanism 10 performs slag removal on the workpiece 5 raw material fixed by the clamping part 6 and the cut workpiece 5. At this moment, there is no need to remove the cut workpiece 5 from the cutting machine separately for slag removal. The slag removal mechanism 10 is intermittently connected to the pressure mechanism 9, so the servo motor 7 can be used to drive the cutting part 4 to reset, and the slag removal mechanism 10 can be driven to slide on the workbench 1 through the pressure mechanism 9, so that the workpiece 5 can be deslagging. During the above operation, there is no need to configure additional power sources such as motors and air pumps, which directly reduces energy consumption. At the same time, the slag removal process is completed synchronously with the reset stroke, avoiding the time waste of separate operations and improving the overall operation efficiency. In addition, the use of mechanical structure can eliminate complex control systems and sensors, and the hardware cost is significantly reduced. The slag removal action strictly follows the reset rhythm of the cutting head to ensure that the slag is cleaned immediately after each cutting to avoid residues affecting the subsequent processing accuracy. At the same time, the slag and oxide layer on the cutting edge are removed in time to reduce secondary pollution, improve the surface finish of the workpiece 5, and reduce thermal stress damage to the metal material.

[0054] In the embodiment provided by the present invention, the clamping portion 6 includes two clamping plates slidably connected to both sides of the work frame 1, so there are four clamping plates, which are symmetrically arranged on both sides of the work frame 1. The two clamping plates can synchronously clamp the raw material of the workpiece 5 and the workpiece 5 after cutting. The work frame 1 is provided with a mounting groove that is compatible with the connecting frame 81. The connecting frame 81 moves inside the mounting groove to adjust the state of the clamping plate. The linkage mechanism 8 includes a connecting frame 81 slidably connected to both sides of the work frame 1. Each connecting frame 81 is fixedly connected to a clamping plate on both sides. When the two connecting frames 81 slide, they will drive the four clamping plates to move synchronously to meet work needs. A second reset spring 87 is provided between each connecting frame 81 and the work frame 1. Specifically, the elastic force of the second reset spring 87 drives the clamping plate away from the workpiece 5, and the state of the clamping plate can be reset according to work needs. The two connecting frames 81 are connected by a transmission unit 82. Specifically, the transmission unit 82 includes a transmission rod 823 that is rotatably connected to the interior of the work frame 1. A transmission gear 822 is mounted on the transmission rod 823. Each connecting frame 81 is fixedly connected to a transmission rack 821. The two transmission racks 821 are respectively engaged on either side of the transmission gear 822. When the transmission gear 822 rotates, the two connecting frames 81 are driven to move via the transmission rack 821, which can drive the clamping portion 6 to fix the workpiece 5 to improve the stability of the workpiece 5 during cutting. A pressure plate 85 is vertically slidably connected to the work frame 1. The pressure plate 85 is connected to the transmission unit 82 by a gear linkage. That is, when the pressure plate 85 moves downward, it drives the transmission rod 823 to rotate via the gear linkage. The state of the clamping portion 6 can be adjusted through the cooperation of the transmission gear 822 and the transmission rack 821, which is more effective. The gear linkage includes a linkage rod 83 rotatably connected to the work frame 1. The linkage rod 83 and the transmission rod 823 are arranged in a vertical position. A gear set 84 is provided between the linkage rod 83 and the transmission rod 823. The gear set 84 includes bevel gears mounted on the linkage rod 83 and the transmission rod 823. The two bevel gears mesh to achieve force transmission. More specifically, the gear linkage also includes a linkage portion 86 disposed between the pressure plate 85 and the linkage rod 83. The linkage portion 86 includes a linkage rack 863 fixedly connected to the pressure plate 85. The linkage rack 863 is vertically slidably connected to the work frame 1 via a positioning block 862. A linkage gear 861 is mounted on the linkage rod 83. The linkage rack 863 meshes with the linkage gear 861. A first return spring 864 is provided between the positioning block 862 and the work frame 1. The elastic force of the first return spring 864 drives the pressure block 92 upward.

[0055] Specifically, in actual use, when it is necessary to drive the two clamping parts 6 closer to each other to clamp the workpiece 5, the servo motor 7 drives the pressure plate 85 to move downward through the pressure mechanism 9. When the pressure plate 85 moves downward, it will drive the linkage rack 863 to drive the linkage gear 861 to rotate, and then drive the linkage rod 83 to rotate. When the linkage rod 83 rotates, it drives the transmission rod 823 to rotate through the gear set 84. When the transmission gear 822 rotates, it will drive the two connecting frames 81 to move through the transmission rack 821, and drive the two clamping parts 6 to move through the connecting frame 81 to clamp the workpiece 5. Therefore, in this process, the clamping part 6 can be driven to fix the workpiece 5 to improve the stability of the workpiece 5 during cutting. When there is no external force driving the pressure plate 85 downward, the elastic force of the second return spring 87 drives the two connecting frames 81 away from each other, driving the transmission rod 823 to rotate in the opposite direction through the transmission unit 82, and the elastic action of the first return spring 864 drives the linkage rack 863 upward, thereby resetting the pressure plate 85 and facilitating subsequent pressure application to the pressure plate 85. The above operation process is repeated to meet the needs of clamping and unlocking the workpiece. More specifically, the gear ratios between the linkage rack 863 and the linkage gear 861, and between the transmission gear 822 and the transmission rack 821 are set according to working requirements.

[0056] In the embodiment provided by the present invention, the pressure mechanism 9 includes a first screw 91 rotatably connected to the work frame 1, and the rotating shaft of the servo motor 7 is coaxially connected to the first screw 91. When the rotating shaft of the servo motor 7 rotates, it will drive the first screw 91 to rotate, and a pressure block 92 is slidably connected to the work frame 1. The pressure block 92 is threadedly connected to the first screw 91. The rotation of the first screw 91 drives the pressure block 92 to slide inside the work frame 1, and the pressure block 92 is slidably connected to the pressure plate 85 through a guide portion 93. More specifically, the guide portion 93 includes a first guide groove 931 and a second guide groove 932 provided on the pressure plate 85. The first guide groove 931 and the second guide groove 932 are respectively located on both sides of the pressure plate 85. At the same time, a flat groove 933 is provided on the pressure plate 85. The flat groove 933 connects the first guide groove 931 and the second guide groove 932. When the workpiece 5 needs to be fixed, the first screw rod 91 rotates at this moment and can drive the pressure block 92 to slide inside the workbench 1. Specifically, the pressure block 92 begins to slide into the flat groove 933 through the first guide groove. Since the first guide groove 931 is in an inclined state, at this moment, when the pressure block 92 slides on one side of the flat groove 933 in the first guide groove 931, it will drive the pressure plate 85 to move downward. When the pressure plate 85 moves downward, it will drive the linkage rack 863 to drive the linkage gear 861 to rotate, and then drive the linkage rod 83 to rotate. When the linkage rod 83 rotates, it drives the transmission rod 823 to rotate through the gear set 84. When the transmission gear 822 rotates, it will drive the two connecting frames 81 to move through the transmission rack 821, and drive the two clamping parts 6 to move through the connecting frame 81 to clamp the workpiece 5. Therefore, in this process, the clamping part 6 can be driven to fix the workpiece 5 to improve the stability of the workpiece 5 during cutting. When the cutting part 4 completes the cutting operation on the workpiece 5, the pressure block 92 will slide from the planar groove 933 to the side of the second guide groove 932 until it slides out from the inside of the planar groove 933. At this time, the elastic force of the second return spring 87 and the first return spring 864 will drive the clamping part 6 to unlock the workpiece 5. After that, the second part 52 of the workpiece 5 that has been cut can be transported to a certain position by starting the second conveying member 3, leaving enough space for subsequent slag removal operations.

[0057] In the embodiment provided by the present invention, the slag removal mechanism 10 includes a mounting plate 101 slidably connected to the work frame 1, and a cleaning unit is provided on the mounting plate 101. Specifically, the cleaning unit includes a vertical cleaning brush 102 horizontally slidably connected to the mounting plate 101, and the vertical cleaning brush 102 is capable of removing slag from the cut portion of the workpiece 5. At the same time, a pressure unit 103 is provided between the vertical cleaning brush 102 and the mounting plate 101. The pressure unit 103 includes a slide bar fixedly connected to the vertical cleaning brush 102, and a mounting spring is provided between the slide bar and the mounting plate 101. The elastic force of the mounting spring drives the vertical cleaning brush 102 to abut against the cut portion of the workpiece 5. Preferably, a horizontal cleaning brush 104 is also slidably connected to the vertical cleaning brush 102 through the pressure unit 103, so that the upper part of the workpiece 5 can be removed, further improving the slag removal efficiency. At the same time, both the vertical cleaning brush 102 and the horizontal cleaning brush 104 are provided with bristles, which can clean the waste slag on the workpiece 5. The work frame 1 is rotatably connected to a reciprocating screw 11, which is threadedly connected to the mounting plate 101 via a threaded sleeve, thereby providing power for the mounting plate 101 to slide. Moreover, when the reciprocating screw 11 continues to rotate, the slag removal mechanism 10 can move back and forth. Preferably, in order to improve the slag removal efficiency and shorten the movement stroke of the slag removal mechanism 10, there are two slag removal mechanisms 10, and similarly, there are two reciprocating screws 11, which are rotatably connected to both sides of the work frame 1, further improving the slag removal efficiency. At the same time, after being cut, the workpiece 5 will form the workpiece 5 raw material body, i.e., the first part 51, and the workpiece 5 after cutting, i.e., the second part 52. At this time, when the slag removal mechanism 10 performs the slag removal operation on the workpiece 5, the vertical cleaning brushes 102 on both sides of the mounting plate 101 are in contact with the first part 51 and the second part 52, respectively, improving the slag removal efficiency and achieving excellent use effect. In an embodiment of the present invention, the pitch of the reciprocating screw 11 and the first screw 91 can be designed according to work needs to meet work needs.

[0058] In the embodiment provided by the present invention, a first connecting rod 12 and a second connecting rod 15 are rotatably connected to the work frame 1. The second connecting rod 15 is connected to the reciprocating screw 11 via a first synchronizer 13, and the first screw 91 is connected to the first connecting rod 12 via a second synchronizer 14. Specifically, the first synchronizer 13 and the second synchronizer 14 have the same structure and working principle, which will not be described in detail here. They can both be existing synchronous wheel assemblies, etc., as long as they meet the transmission operation. A one-way transmission member 16 is provided between the first connecting rod 12 and the second connecting rod 15. That is, when the servo motor 7 rotates forward, it drives the first screw 91 to rotate, and the first connecting rod 12 is driven to rotate via the second synchronizer 14. At this time, since the one-way transmission member 16 is provided between the first connecting rod 12 and the second connecting rod 15, it will not drive the second connecting rod 15 to rotate, that is, the reciprocating screw 11 will be in a stationary state, and the slag removal mechanism 10 will not move. Conversely, when the servo motor 7 rotates in the reverse direction, the one-way transmission member 16 drives the second connecting rod 15 to rotate, thereby enabling the slag removal mechanism 10 to remove slag from the workpiece 5 via the reciprocating screw 11. Specifically, the one-way transmission member 16 includes a wedge-shaped rod 161 slidably connected to the first connecting rod 12. The first connecting rod 12 has a slot 164 defined therein. The wedge-shaped rod 161 is slidably connected to the first connecting rod 12 via the slot 164, and a compression spring 163 is disposed between the slot 164 and the wedge-shaped rod 161. Furthermore, a wedge-shaped slot 162 is defined on the second connecting rod 15. The elastic force of the compression spring 163 forces the wedge-shaped rod 161 to engage within the slot 162. When the servo motor 7 rotates in the forward direction, the wedge surface of the wedge-shaped rod 161 contacts the wedge surface of the slot 162, preventing the second connecting rod 15 from rotating. On the contrary, when the servo motor 7 rotates in reverse, the wedge-shaped rod 161 will directly contact the wedge-shaped slot 162, which will drive the second connecting rod 15 to rotate to meet the subsequent movement of the reciprocating screw rod 11.

[0059] In the embodiment provided by the present invention, an adjustment block 94 is slidably connected to the pressure block 92 via a positioning portion 941. Specifically, the positioning portion 941 includes a positioning rod fixedly connected to the adjustment block 94, a vertical slot is provided on the side wall of the pressure block 92, the positioning rod is slidably connected in the vertical slot, and a spring is provided between the positioning rod and the vertical slot. Preferably, the elastic force of the spring on the positioning rod is greater than the elastic force of the locking spring 952, so that in the absence of external force, the elastic force of the spring drives the top of the adjustment block 94 to be horizontal with the top of the pressure block 92. A locking member 95 is provided between the adjustment block 94 and the pressure block 92 to lock the state of the adjustment block 94 and the pressure block 92, so that the state of the adjustment block 94 can be adjusted as needed. The locking member 95 includes a locking rod 951 slidably connected to the interior of the pressure block 92. The locking rod 951 is inserted into the adjustment block 94 through a locking slot 953. A locking spring 952 is disposed between the locking rod 951 and the pressure block 92. The elastic force of the locking spring 952 causes the locking rod 951 to slide out of the locking slot 953. The adjustment block 94 also has a vertically slidably connected clamping member 96 for restraining the locking rod 951. When the clamping member 96 is engaged with the locking rod 951, the locking rod 951 is fixed in position. When the clamping member 96 slides out of the locking rod 951, the elastic force of the locking spring 952 causes the locking rod 951 to slide out of the locking slot 953. At this point, when an external force drives the adjustment block 94 to slide, the adjustment block 94 slides on the pressure block 92 via the positioning portion 941. The clamping member 96 includes a clamping rod 961 that is slidably connected to the pressure block 92. The clamping rod 961 is clamped to the locking rod 951 through a clamping groove 964. A clamping spring 963 is provided between the clamping rod 961 and the pressure block 92. The elastic force of the clamping spring 963 drives the clamping rod 961 to be clamped and seated in the clamping groove 964, thereby fixing the state of the locking rod 951. Preferably, the elastic force of the clamping spring 963 is greater than the elastic force of the locking spring 952. When there is no external force, the elastic force of the clamping spring 963 drives the clamping rod 961 to be clamped in the clamping groove 964, thereby clamping the locking rod 951 in the locking groove 953.

[0060] In the embodiment provided by the present invention, the work frame 1 is further provided with an unlocking portion 97 for driving the clamping rod 961 to slide out from the clamping groove 964 in which it is located. Specifically, the unlocking portion 97 is located in the middle position of the work frame 1. When the rotation axis of the servo motor 7 is reversed, the first screw 91 drives the pressure block 92 to slide in the opposite direction through the unlocking portion 97, so that the unlocking portion 97 pulls the clamping rod 961 out of the clamping groove 964. When the unlocking portion 97 drives the clamping rod 961 to slide out of the clamping groove 964, the slag removal mechanism 10 has completed the slag removal operation on the workpiece 5. The unlocking portion 97 includes a mounting block 972 mounted on the work frame 1, and an unlocking block 971 is slidably connected to the mounting block 972 via an elastic portion 973; the clamping rod 961 is fixedly connected to the connecting block 962, and the connecting block 962 is provided with an unlocking groove 976 that matches the unlocking block 971. Specifically, the elastic portion 973 includes a pressure rod fixedly connected to the mounting block 972. The unlocking block 971 is fixedly connected to the pressure rod, and the pressure rod is slidably connected to the mounting block 972 through a slot, with an elastic unit disposed between the pressure rod and the slot. Furthermore, the unlocking block 971 defines a first abutting surface 974 and a second abutting surface 975, each of which intermittently contacts the connecting block 962. Both the first abutting surface 974 and the second abutting surface 975 are wedge-shaped surfaces.

[0061] During the process, when the servo motor 7 rotates forward, the driving screw will drive the pressure block 92 to slide on the workbench 1. At this time, the pressure block 92 is in the sliding stroke, and the connecting block 962 will abut against the first abutting surface 974. At this time, the pressure rod will be driven through the hole groove through the first abutting surface 974 to slide on the pressure block 92, so that the connecting block 962 is in a stationary state through the unlocking part 97.

[0062] When the servo motor 7 rotates in reverse, the screw drives the pressure block 92 to slide in the opposite direction. At this moment, the pressure block 92 enters the flat groove 933 through the second conducting groove, and then drives the clamping part 6 to fix the workpiece 5 again through the linkage mechanism 8. When the pressure block 92 enters the flat groove 933 on the pressure plate 85 through the second conducting groove, more specifically, the adjustment block 94 contacts the second conducting groove and slides inside the flat groove 933. At this moment, the adjustment block 94 and the pressure block 92 are integrated into a whole under the action of the locking member 95 and the clamping member 96, so that the pressure plate 85 can be driven to move downward, that is, after the clamping part 6 is driven to fix the workpiece 5 through the linkage mechanism 8, the reciprocating screw 11 is driven to rotate through the cooperation between the first connecting rod 12 and the second connecting rod 15, and then the slag removal mechanism 10 can be driven to slide on the workpiece 5 to perform slag removal on the workpiece 5. When the pressure block 92 moves in the reverse direction for a certain distance, the reciprocating screw 11 has driven the slag removal mechanism 10 to move back and forth, and the slag removal operation has been completed on the first part 51 and the second part 52 on the workpiece 5. At this moment, the connecting block 962 just passes the unlocking block 971. Figure 16When the locking lever 951 is released, the elastic force of the locking spring 952 drives the locking lever 951 to slide out of the locking groove 953 in which it is located. At this moment, the adjusting block 94 releases the restriction on the pressure block 92. At this point, the adjustment block 94 is slidably connected to the pressure block 92 via the positioning portion 941. This means that the pressure plate 85 is reset under the action of the first return spring 864 and the second return spring 87, passively driving the adjustment block 94 to slide with the pressure block 92. This change in direction effectively unlocks the pressure plate 85. When the pressure plate 85 is reset, the clamping portion 6 unlocks the workpiece 5. Once the workpiece 5 is unlocked, the first and second conveying members 2 and 3 are activated to move the first and second portions 51 and 52 of the workpiece 5, thereby transporting the cut workpiece 5 to the desired location and the next section of the workpiece 5 to be cut to a desired location for subsequent cutting operations, significantly improving work efficiency. During this operation, the workpiece 5 can be transported without the need for the cutting unit 4 to be reset, effectively reducing the processing efficiency of a single workpiece 5, reducing the processing time per piece by 30%-45%. This nonlinear efficiency improvement has a multiplier effect in high-speed continuous production. Compared to conventional processes, where reset and conveying times occur sequentially, the total time is the sum of the two. In this application, however, these two processes partially overlap. For example, shortly after the cutting unit 4 begins to reset, the unlocking unit 97 unlocks the adjustment block 94, allowing the clamping unit 6 to unlock the workpiece 5. At this point, the conveyor can start. Therefore, the total time may be close to the larger of the reset time or the conveying time, rather than the sum of the two. This is similar to parallel processing in a production line, reducing idle time and greatly improving work efficiency.

[0063] When the pressure block 92 is completely disengaged from the planar groove 933 on the pressure plate 85, the adjustment block 94 is driven to reset under the restriction of the positioning portion 941. At this time, the locking rod 951 is restricted by the clamping spring 963. The elastic force of the clamping spring 963 drives the clamping rod 961 to be clamped in the clamping groove 964, and the locking rod 951 is clamped in the locking groove 953 to facilitate subsequent processing and use.
