Description

Technical Field

[0001] This invention belongs to the technical field of metal circular saw cutting equipment, and particularly relates to a sawing device for petroleum alloy profiles. Background Technology

[0002] In the processes of oil extraction, transportation, and oil equipment manufacturing, a large amount of alloy profiles with high strength, corrosion resistance, and wear resistance are required. When processing these profiles to a fixed length, circular saws are typically used for sawing. When the circular saw is working, a drive motor drives the circular saw blade to rotate at high speed, causing the blade to feed relative to the profile, thereby gradually cutting the profile.

[0003] For high-strength petroleum alloy profiles, as the circular saw blade approaches the bottom of the profile, there is still a certain connection area on both sides of the cut. Simultaneously, influenced by clamping force, the profile's own weight, internal material stress, and thermal deformation during sawing, the existing saw kerfs may tend to converge. When the sides of the cut are squeezed towards the circular saw blade, it easily increases the frictional resistance on both sides of the blade. In severe cases, this can lead to saw jamming or blade sticking, increasing the load on the drive motor and potentially causing the circular saw blade to break teeth, deflect, or even be damaged.

[0004] Chinese patent discloses a steel plate anti-pinch precision sawing machine, publication number CN115609077B. This solution sets up an anti-pinch structure for steel plate sawing. After the steel plate is cut, the corresponding anti-pinch components restrict the cut from continuing to move closer, thereby reducing the possibility of the saw blade being clamped.

[0005] However, in the above solutions, the anti-pinch operation requires an independent execution structure that acts on the already formed sawing position. For profiles with different cross-sectional dimensions and cutting states, the movement position of the anti-pinch components needs to be controlled accordingly. When processing petroleum alloy profiles using a lifting circular saw, there is still room for improvement in how to directly utilize the downward sawing stroke of the circular saw blade itself to cause the profile on the cut side to move laterally under buffer control in the later stage of sawing, thereby reducing the clamping effect of the profile on the circular saw blade, and further completing the loosening, unloading, and surface sawdust cleaning of the cut profile. Summary of the Invention

[0006] This invention provides a sawing device for petroleum alloy profiles, which aims to solve the problems that the two sides of the cut are prone to clamping the circular saw blade during the circular saw cutting process, and that the cut profiles need to be manually loosened, transferred, and the surface sawdust cleaned.

[0007] The present invention is implemented as follows: a sawing device for petroleum alloy profiles includes a processing machine tool, a sawing device body, a lifting and moving device, a protective mechanism, and a cleaning mechanism. The sawing device body is provided with a circular saw blade and connected to the free end of the lifting and moving device. The protective mechanism includes a pusher, a connecting threaded sleeve, a transmission rod, a sliding seat, a buffer spring, a slider, a roller, and a transmission plate. The connecting threaded sleeve is rotatably connected to the sawing device body. The transmission rod is threadedly connected to the connecting threaded sleeve. The transmission rod is rotatably connected to the slider. The roller is rotatably connected to the transmission plate and located on the movement path of the slider.

[0008] When the sawing device body descends, it drives the roller through the connecting threaded sleeve, transmission rod and slider, causing the transmission plate to rotate and push the pusher. The pusher, through the buffer spring, drives the sliding seat to move away from the circular saw blade.

[0009] Preferably, the protective mechanism further includes a fixed plate and a mounting base. The fixed plate is fixedly connected to the outside of the lifting and moving device, the mounting base is fixedly connected to the fixed plate, the middle part of the transmission rod is slidably connected to the mounting base, the slider is vertically slidably connected to the inside of the mounting base, and the transmission plate is rotatably connected to the mounting base.

[0010] Preferably, the sliding seat is slidably connected to the inner side of the machine tool, and buffer springs are provided on both sides of the sliding seat. Pushing members are fixedly connected to the ends of the two buffer springs away from the sliding seat, and at least one pushing member is located within the rotation range of the transmission plate.

[0011] Preferably, when the transmission plate rotates, it pushes the corresponding pusher, and the pusher transmits the thrust to the sliding seat through a buffer spring. The buffer spring is used to elastically buffer the pushing action between the pusher and the sliding seat.

[0012] Preferably, the protective mechanism further includes grippers, a support base, and two double-ended electric push rods. The support base is fixedly connected to the top of the sliding seat, and the two double-ended electric push rods are spaced apart on the support base. Each double-ended electric push rod has a gripper rotatably connected to its two output ends. The four grippers are hinged to the support base for jointly clamping the petroleum alloy profile body.

[0013] Preferably, the protective mechanism further includes a baffle, which is fixedly connected to the inside of the machine tool and located on one side of the slide seat, for defining the initial position of the slide seat.

[0014] Preferably, the protective mechanism further includes a lifting electric push rod and two support seats, one of which is fixedly connected to one side of the support seat, the lifting electric push rod is fixedly connected to the other side of the support seat, and the other support seat is fixedly connected to the output end of the lifting electric push rod. The two support seats are used to jointly support the petroleum alloy profile body.

[0015] Preferably, the cleaning mechanism includes a storage box, a transmission pipe, a cleaning brush, a positioning plate, and a trigger switch. The positioning plate is fixedly connected to the inner side of the machine tool, and the trigger switch is fixedly connected to the outer side of the positioning plate and located on the moving path of the sliding seat. The trigger switch is electrically connected to two double-ended electric push rods and a lifting electric push rod, respectively.

[0016] Preferably, when the sliding seat moves to the position of the trigger switch, the trigger switch is triggered, and the two double-ended electric push rods drive the four jaws to release the gripping of the petroleum alloy profile body. The lifting electric push rod drives the corresponding receiving seat to move upward, so that the cut petroleum alloy profile body is in an inclined unloading state.

[0017] Preferably, the storage box is located on one side of the processing machine tool, one end of the transmission pipe corresponds to the unloading position of the receiving seat, and the other end is connected to the storage box. The cleaning brush is fixedly connected to the inside of the transmission pipe and is used to clean the surface of the petroleum alloy profile body moving along the transmission pipe.

[0018] Compared with related technologies, the petroleum alloy profile sawing device provided by the present invention has the following beneficial effects:

[0019] 1. This invention forms a mechanical transmission path that is linked to the descent of the sawing device body by connecting the threaded sleeve, transmission rod, slider, roller, transmission plate, pusher, buffer spring, and sliding seat. When the sawing device body drives the circular saw blade to descend for cutting, the threaded sleeve descends synchronously and drives the slider to move via the transmission rod. The slider further squeezes the roller, causing the transmission plate to rotate. The transmission plate gradually transmits lateral force to the sliding seat through the pusher and buffer spring, causing the cut end of the clamped profile to move away from the circular saw blade. This reduces the possibility of continued clamping force on both sides of the cut, lowers the risk of the circular saw blade jamming, stuck, and abnormal load, and eliminates the need for a separate power mechanism dedicated to driving the sliding seat.

[0020] 2. In this invention, a buffer spring is provided between the pusher and the sliding seat. The buffer spring does not serve as the reset force for the sliding seat. Instead, it generates a certain elastic compression after the transmission plate begins to push the pusher. This allows the rigid pushing force generated by the transmission plate to be gradually transmitted to the sliding seat through the buffer spring. When the circular saw blade has not completely cut the profile, it can prevent the sliding seat from instantly generating a large displacement and directly pulling the remaining connecting parts of the profile. This makes the movement of the sliding seat more flexible, reducing the possibility of abnormal breakage, end deformation, and mechanical impact on the profile while achieving the goal of moving the cutting side away from the circular saw blade.

[0021] 3. This invention uses four grippers to hold the profile to be cut. After the sliding seat moves to the trigger position, the two double-ended electric push rods can be released from the grip by the trigger switch, and one of the receiving seats is raised by the lifting electric push rod, so that a height difference is formed between the two receiving seats, thereby causing the cut profile to automatically tilt and move towards the direction of the transmission tube. When the profile passes through the transmission tube, it comes into elastic contact with the cleaning brush, which can remove the metal chips and dust attached to the surface of the profile during the sawing process, and finally enter the storage box, realizing the continuous coordination of loosening, tilting and unloading, surface cleaning and centralized collection.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] Example 1

[0034] A preferred embodiment of the petroleum alloy profile sawing device provided by the present invention is as follows: Figures 1 to 8 The image shows a petroleum alloy profile sawing device, comprising a machine tool 1, a sawing device body 2, a lifting and moving device 3, a protective mechanism 4, a cleaning mechanism 5, and a petroleum alloy profile body 6. The machine tool 1 forms the placement position of the petroleum alloy profile body 6 and the mounting base for each mechanism. The petroleum alloy profile body 6 is placed along the length of the machine tool 1, and the sawing device body 2 is positioned at the sawing position of the machine tool 1. The sawing device body 2 includes a drive motor, a rotating spindle, and a circular saw blade. The circular saw blade is mounted on the rotating spindle, and the drive motor can drive the circular saw blade to rotate through the rotating spindle, thereby sawing the petroleum alloy profile body 6.

[0035] In this embodiment, the lifting and moving device 3 includes a vertically arranged guide rail and a lifting device that moves up and down along the guide rail. The sawing device body 2 is fixedly connected to the free end of the lifting device. When the lifting device is activated, it can drive the sawing device body 2 to move up and down along the guide rail, so that the circular saw blade can feed towards the petroleum alloy profile body 6 or retract away from the petroleum alloy profile body 6. The lifting device can adopt conventional linear drive structures such as electric push rods, electric cylinders, or lead screw lifting assemblies. In this embodiment, an electrically driven linear lifting assembly is preferred. The guide rail is used to restrict the movement direction of the sawing device body 2, thereby improving the stability of the circular saw blade during the lifting and sawing process.

[0036] In a further preferred embodiment of the present invention, the protective mechanism 4 includes a fixed plate 401, a pusher 402, a connecting threaded sleeve 403, a transmission rod 404, a mounting base 405, a sliding base 406, a buffer spring 407, a gripper 408, a support base 409, a double-ended electric push rod 410, a baffle 412, a slider 413, a roller 414, a transmission plate 415, a lifting electric push rod 416, and a receiving base 417. The fixed plate 401 is fixedly connected to the outside of the fixed part of the lifting and moving device 3, and the mounting base 405 is fixedly connected to the fixed plate 401, so that the fixed plate 401 and the mounting base 405 maintain a fixed position relative to the machine tool 1 during the lifting and lowering process of the sawing device body 2; the sawing device body 2 is connected to the moving part of the lifting and moving device 3, so that the sawing device body 2 can move vertically relative to the mounting base 405.

[0037] In this embodiment, the threaded sleeve 403 is rotatably connected to the outside of the sawing device body 2, and rises and falls synchronously with the sawing device body 2 during normal sawing. The transmission rod 404 is threadedly connected to the inside of the threaded sleeve 403, and its middle portion passes through the mounting base 405 and is slidably connected to it, allowing the transmission rod 404 to move vertically relative to the mounting base 405. The lower end of the transmission rod 404 extends into the slider 413 and is rotatably connected to it. The slider 413 is vertically slidably connected to the mounting base 405. Therefore, when the threaded sleeve 403 descends with the sawing device body 2, it can drive the slider 413 to move downwards along the mounting base 405 via the transmission rod 404.

[0038] It should be noted that during normal sawing, the threaded sleeve 403 does not need to rotate on its own to transmit power. The threaded sleeve 403 mainly descends as a whole with the sawing device body 2, and drives the transmission rod 404 to move axially through the threaded connection with the transmission rod 404. The transmission rod 404 and the slider 413 are rotatably connected, which allows the transmission rod 404 to transmit vertical force to the slider 413, while reducing unnecessary torsional constraints at the connection position between the transmission rod 404 and the slider 413.

[0039] In a further preferred embodiment of the present invention, the transmission plate 415 is rotatably connected to the mounting base 405, and the roller 414 is rotatably connected to one end of the transmission plate 415. The roller 414 is located on the downward movement path of the slider 413. After the sawing device body 2 descends to a certain position, the slider 413 contacts the roller 414. As the slider 413 continues to descend, it exerts a squeezing effect on the roller 414, causing the roller 414 to drive the transmission plate 415 to rotate around the rotational connection position between the transmission plate 415 and the mounting base 405. The roller 414 can roll when in contact with the slider 413, thereby reducing the sliding friction between the two.

[0040] In this embodiment, the sliding seat 406 is slidably connected to the inner side of the machine tool 1. Buffer springs 407 are respectively provided on both sides of the sliding seat 406. The ends of the two buffer springs 407 away from the sliding seat 406 are respectively fixedly connected to the pushing member 402. The outer side of the pushing member 402 is located in the area where the transmission plate 415 can exert its force. When the transmission plate 415 is driven to rotate by the roller 414, the transmission plate 415 abuts against the corresponding pushing member 402 and pushes the pushing member 402 to move. The pushing member 402 further compresses the corresponding buffer spring 407, transmitting thrust to the sliding seat 406 through the buffer spring 407, causing the sliding seat 406 to move along the machine tool 1 in a direction away from the circular saw blade.

[0041] In a further preferred embodiment of the present invention, the buffer spring 407 is a compression spring. The buffer spring 407 is mainly used to form an elastic buffer between the pusher 402 and the sliding seat 406, and does not serve as an automatic reset structure for the sliding seat 406. After the transmission plate 415 pushes the pusher 402, the buffer spring 407 first undergoes a certain compression deformation, and gradually transmits the force to the sliding seat 406 as the compression increases, so that the lateral thrust on the sliding seat 406 is gradually established, avoiding the transmission plate 415 directly and rigidly pushing the sliding seat 406 to produce instantaneous displacement.

[0042] In this embodiment, when the circular saw blade has cut into the petroleum alloy profile body 6 to a certain depth, and there is still a small amount of uncut area in the profile, the buffer spring 407 can reduce the pulling effect on the uncut area caused by the sudden movement of the sliding seat 406. As the circular saw blade continues to descend and cut, the sliding seat 406 drives the support seat 409 and the petroleum alloy profile body 6 located on the cutting side to gradually move away from the circular saw blade, thereby giving the formed kerf a tendency to release, reducing the possibility that the petroleum alloy profile body 6 will be squeezed to both sides of the circular saw blade due to its own weight, clamping force, internal material stress or cutting thermal deformation.

[0043] In a further preferred embodiment of the present invention, a baffle 412 is fixedly connected to the inside of the machine tool 1 and located on one side of the sliding seat 406. The baffle 412 is used to limit the initial position of the sliding seat 406 when it begins a sawing cycle. Before processing begins, the sliding seat 406 is brought into contact with the baffle 412, thereby keeping the support seat 409, the gripper 408, and the receiving seat 417 in the predetermined sawing position. The baffle 412 only serves to limit the initial position and does not automatically drive the sliding seat 406 to reset via the baffle 412 or the buffer spring 407.

[0044] Example 2

[0045] Based on Example 1, a preferred embodiment of the petroleum alloy profile sawing device provided by the present invention is as follows: Figures 3 to 5As shown: The support base 409 is fixedly connected to the top of the sliding base 406. Therefore, when the sliding base 406 moves away from the circular saw blade, it can drive the support base 409 to move synchronously, and further drive the cutting side of the petroleum alloy profile body 6 clamped at the support base 409 to move accordingly.

[0046] In this embodiment, two double-ended electric actuators 410 are spaced apart on the support base 409 along the extension direction of the petroleum alloy profile body 6. Each double-ended electric actuator 410 has two oppositely arranged output ends, and each output end is rotatably connected to a gripper 408. Therefore, the two double-ended electric actuators 410 correspond to a total of four grippers 408. The four grippers 408 are respectively hinged to the support base 409. When the two output ends of the double-ended electric actuators 410 extend or retract, they can push the corresponding two grippers 408 to rotate around the hinge position, so that the grippers 408 move closer to or away from the petroleum alloy profile body 6, thereby realizing clamping and releasing.

[0047] In a further preferred embodiment of the present invention, four grippers 408 form two clamping positions along both sides of the petroleum alloy profile body 6, enabling the petroleum alloy profile body 6 to remain stable during the sawing process. When the two double-ended electric push rods 410 are simultaneously in the clamping state, the lateral movement of the support base 409 can drive the cutting side of the petroleum alloy profile body 6 to move synchronously through the four grippers 408, without causing significant slippage between the profile and the support base 409.

[0048] In this embodiment, two support seats 417 are provided on the top of the support base 409. One support seat 417 is fixedly connected to one side of the support base 409, and the lifting electric push rod 416 is fixedly connected to the other side of the support base 409. The other support seat 417 is fixedly connected to the output end of the lifting electric push rod 416. When the lifting electric push rod 416 is in the retracted state, the receiving positions of the two support seats 417 are basically consistent, and they are used to jointly support the petroleum alloy profile body 6. After the lifting electric push rod 416 extends, the corresponding support seat 417 moves upward, so that a height difference is formed between the two support seats 417.

[0049] In a further preferred embodiment of the present invention, the cleaning mechanism 5 includes a storage box 501, a transmission pipe 502, a cleaning brush 503, a positioning plate 504, and a trigger switch 505. The positioning plate 504 is fixedly connected to the inside of the processing machine tool 1, and the trigger switch 505 is fixedly connected to the outside of the positioning plate 504 and located on the moving path of the sliding seat 406. The position of the trigger switch 505 corresponds to the position that the sliding seat 406 can reach after the circular saw blade has finished cutting the petroleum alloy profile body 6, so that the sliding seat 406 will not prematurely trigger the release action of the gripper 408 during normal anti-pinch movement.

[0050] In this embodiment, the trigger switch 505 can be a mechanical limit switch, a micro switch, or a proximity switch, preferably a mechanical limit switch. The trigger switch 505 is connected to the control circuits of the two double-ended electric push rods 410 and the lifting electric push rod 416, respectively. When the sliding seat 406 moves to the position of the trigger switch 505 and triggers the trigger switch 505, the two double-ended electric push rods 410 actuate, causing the four grippers 408 to rotate and release the gripping of the already cut petroleum alloy profile body 6, and simultaneously or subsequently controlling the extension of the lifting electric push rod 416.

[0051] In this embodiment, to avoid the petroleum alloy profile body 6 being directly lifted by the lifting electric push rod 416 while still in the clamped state, a conventional control circuit can be used to allow the two double-ended electric push rods 410 to release the clamp first, and then extend the lifting electric push rod 416. The above control can be implemented by a relay, a time-delay relay, or a conventional controller, which is only used to complete the action control between two known electric actuators. Those skilled in the art can make conventional connections based on the trigger switch 505 and the working voltage of the corresponding electric push rod.

[0052] In a further preferred embodiment of the present invention, after the lifting electric push rod 416 extends, it drives the corresponding receiving seat 417 to rise, forming a height difference between the two receiving seats 417, causing the petroleum alloy profile body 6, which has been released from clamping, to tilt towards the inlet direction of the transmission pipe 502. The inlet of the transmission pipe 502 is located at a position where the petroleum alloy profile body 6 can slide down after being cut. The petroleum alloy profile body 6 enters the transmission pipe 502 under its own gravity, thereby reducing the need for operators to directly pick up materials near the circular saw blade.

[0053] In this embodiment, the transfer pipe 502 is inclined between the machine tool 1 and the storage box 501, with the end of the transfer pipe 502 closer to the machine tool 1 being higher than the end closer to the storage box 501, so that the petroleum alloy profile body 6 entering the transfer pipe 502 can move towards the storage box 501 under its own gravity. The internal channel size of the transfer pipe 502 is larger than the maximum cross-sectional size of the position that the petroleum alloy profile body 6 needs to pass through, to avoid the profile getting stuck inside the transfer pipe 502.

[0054] In a further preferred embodiment of the present invention, the transmission pipe 502 may be made of 304 stainless steel pipe, galvanized steel pipe or other metal pipe with corresponding mechanical strength. In this embodiment, 304 stainless steel pipe is preferred, so that the transmission pipe 502 has good wear resistance and corrosion resistance, and is easy to clean sawdust, oil stains and other attachments.

[0055] In this embodiment, the cleaning brush 503 is fixedly connected to the inside of the transmission pipe 502. The bristles of the cleaning brush 503 extend into the internal channel of the transmission pipe 502 and can make elastic contact with the surface of the petroleum alloy profile body 6. The cleaning brush 503 is preferably made of PA66 wear-resistant nylon bristles. PA66 bristles have certain elasticity and wear resistance, which can reduce the possibility of additional scratches on the profile surface when using rigid metal bristles while cleaning sawdust adhering to the profile surface. Depending on the cross-sectional shape of the petroleum alloy profile body 6, the cleaning brush 503 can be a strip brush body arranged along the inner wall of the transmission pipe 502 or multiple sets of spaced brush bodies.

[0056] In a further preferred embodiment of the present invention, the storage box 501 is disposed at the lower end of the transmission pipe 502, and the top of the storage box 501 is provided with an inlet connected to the transmission pipe 502. The storage box 501 is preferably formed by welding 304 stainless steel plate, so that it can withstand the cut petroleum alloy profile body 6 and sawdust entering with the profile, while improving the corrosion resistance of the box body after contact with oil and moisture; in other embodiments, the storage box 501 can also be made of corrosion-resistant carbon steel plate.

[0057] In this embodiment, during actual processing, the petroleum alloy profile body 6 is first placed on the processing machine tool 1, with the side to be cut supported by two receiving seats 417. Then, two double-ended electric push rods 410 are activated, each driving one of the four corresponding grippers 408 to rotate, causing the four grippers 408 to clamp the petroleum alloy profile body 6. Subsequently, the sawing device body 2 is activated, causing the circular saw blade to rotate, and the sawing device body 2 is lowered via the lifting and moving device 3 to perform sawing.

[0058] As the sawing device body 2 descends, the connecting threaded sleeve 403 descends synchronously. The connecting threaded sleeve 403 drives the slider 413 to descend along the mounting base 405 via the transmission rod 404. After the slider 413 moves to the position of the roller 414, it squeezes the roller 414, causing the roller 414 to drive the transmission plate 415 to rotate. The transmission plate 415 further pushes the corresponding pusher 402, which compresses the buffer spring 407 and gradually transmits the thrust to the sliding base 406 through the buffer spring 407.

[0059] In this embodiment, after the sliding seat 406 is subjected to the thrust transmitted by the buffer spring 407, it drives the support seat 409 and the clamped petroleum alloy profile body 6 to move in a direction away from the circular saw blade. The buffer spring 407 can reduce the instantaneous impact generated when the transmission plate 415 directly and rigidly drives the sliding seat 406. When there are still a small number of uncut connection areas in the petroleum alloy profile body 6, the movement of the cutting side has a certain buffering process, thereby reducing the possibility of abnormal breakage caused by sudden pulling of the connection area.

[0060] When the circular saw blade finishes cutting the petroleum alloy profile body 6 and the sliding seat 406 moves to the position of the trigger switch 505, the sliding seat 406 triggers the trigger switch 505. The two double-ended electric push rods 410 drive the four grippers 408 to release the gripping action. The lifting electric push rod 416 then extends and drives the corresponding receiving seat 417 to move upward, causing the cut petroleum alloy profile body 6 to tilt towards the transmission pipe 502 and enter the transmission pipe 502 under its own gravity.

[0061] When the petroleum alloy profile body 6 moves along the transmission pipe 502, its surface comes into contact with the cleaning brush 503. The cleaning brush 503 removes the metal sawdust and debris that are attached to the surface of the petroleum alloy profile body 6 after cutting. After cleaning, the petroleum alloy profile body 6 continues to move downward along the transmission pipe 502 and enters the storage box 501, thereby completing the collection of the cut profile.

[0062] After completing one sawing and unloading cycle, the lifting and moving device 3 first moves the sawing device body 2 upward to the initial sawing position. As the sawing device body 2 rises, the connecting threaded sleeve 403 and the transmission rod 404 move upward synchronously. The transmission rod 404 drives the slider 413 upward and gradually disengages from the roller 414, causing the transmission plate 415 to release its continuous pushing action on the pusher 402. After the transmission plate 415 releases its action, the operator manually pushes the sliding seat 406 in the reverse direction along the machine tool 1 until the sliding seat 406 re-fits with the baffle 412. The baffle 412 determines the initial position of the sliding seat 406 for the next sawing cycle. Then, the lifting electric push rod 416 is controlled to return to the retracted state, and the two double-ended electric push rods 410 are returned to the clamping state, ready for the next sawing operation.

[0063] In summary, this invention utilizes the downward movement of the sawing device body 2 itself to cause the connecting threaded sleeve 403, transmission rod 404, and slider 413 to move downward synchronously. The slider 413 squeezes the roller 414, causing the transmission plate 415 to rotate. The transmission plate 415 further pushes the pusher 402 and flexibly transmits lateral force to the sliding seat 406 through the buffer spring 407. This allows the cut side of the petroleum alloy profile body 6 to gradually move away from the circular saw blade in the later stages of sawing, thereby reducing the possibility of the saw blade being clamped on both sides of the saw kerf. After sawing is completed, the sliding seat 406 triggers the trigger switch 505, causing the four grippers 408 to release their clamps and the corresponding receiving seat 417 to be lifted by the lifting electric push rod 416. This allows the cut petroleum alloy profile body 6 to tilt and enter the transmission pipe 502. After the surface sawdust is cleaned by the cleaning brush 503, it enters the storage box 501, achieving continuous coordination of anti-clamping sawing, loosening, unloading, cleaning, and collection.
