Description

Technical Field

[0001] The present invention relates to a sawing machine, and more particularly to a circular sawing machine. Background Art

[0002] A circular sawing machine performs a rotary sawing motion through a saw blade on a saw frame, and at the same time makes a feeding motion (generally horizontal feeding) along with the saw frame to achieve sawing of steel plates and the like. The circular sawing machine itself is a relatively mature technology, but when sawing a larger steel plate, the circular sawing machine not only has inconvenient feeding of the steel plate, but also is prone to vibration of the stock plate during the sawing process of the steel plate, which affects the sawing quality.

[0003] On the other hand, when a circular sawing machine saws a larger steel plate, due to the long length and narrow width of the saw kerf, the saw kerf may shrink during the process of the saw blade sawing the steel plate, which affects the rotary sawing motion of the saw blade, reduces the sawing efficiency of the steel plate, and even causes the saw blade to jam, affecting the normal operation of the circular sawing machine. Summary of the Invention

[0004] The first object of the present invention is to provide a circular sawing machine that is not only convenient for feeding, but also can effectively avoid the problem that the vibration of the stock plate during the sawing process of the steel plate affects the sawing quality.

[0005] Another object of the present invention based on the first object is to provide a circular sawing machine that can effectively avoid the problem that the shrinkage of the saw kerf during the sawing process of the steel plate affects the rotary sawing motion of the saw blade and even causes the saw blade to jam.

[0006] The technical solution of the present invention is as follows:

[0007] A circular sawing machine includes:

[0008] A frame, on which a processing plane is provided;

[0009] A sawing device, which includes a transverse movement track provided on the frame, a saw frame moving along the transverse movement track, a saw frame reciprocating movement mechanism for driving the saw frame to move, a saw blade rotatably provided on the saw frame, and a saw blade rotation driving mechanism provided on the saw frame for driving the saw blade to rotate;

[0010] A steel plate feeding device for feeding a steel plate to be cut onto the processing plane. The steel plate feeding device includes a longitudinal movement track provided on the frame, a feeding frame moving along the longitudinal movement track, a feeding frame reciprocating movement mechanism for driving the feeding frame to move, and a steel plate clamping mechanism provided on the feeding frame. The longitudinal movement track is perpendicular to the transverse movement track;

[0011] A steel plate pressing device, which includes a pressing block located above the processing plane and a pressing block lifting mechanism for driving the pressing block to lift and lower.

[0012] The disk sawing machine of this solution realizes the automatic feeding of the steel plate to be cut through the steel plate feeding device, which is convenient for feeding. Before sawing the steel plate, the steel plate is firmly pressed and fixed on the processing plane by the steel plate pressing device. In this way, during the sawing process of the steel plate, the problem that the vibration of the material plate is likely to occur during the sawing process of the steel plate and affect the sawing quality can be effectively avoided.

[0013] Preferably, it further includes a transverse saw slot maintaining device. The transverse saw slot maintaining device includes a transverse insert piece and an insert piece reciprocating movement mechanism for driving the transverse insert piece to move. The moving direction of the transverse insert piece is parallel to the transverse movement track, and the transverse insert piece is located on one side of the saw disk. During the process of the saw disk of the disk sawing machine sawing the steel plate, the insert piece reciprocating movement mechanism drives the transverse insert piece to insert into the saw slot of the steel plate. In this way, the width of the saw slot can be maintained, and effectively avoid the problem that during the sawing process of the steel plate, due to the shrinkage of the saw slot, it affects the rotary sawing movement of the saw disk and even causes the saw disk to be stuck.

[0014] Preferably, it further includes a first anti-error protection device. The transverse saw slot maintaining device further includes a transverse movement support. The transverse insert piece is fixed on the transverse movement support. The first anti-error protection device includes a support block fixed on the transverse movement support and a saw frame block arranged at the bottom of the saw frame for cooperating with the support block. The saw frame block is located between the support block and the saw disk. When the insert piece reciprocating movement mechanism drives the transverse insert piece to move towards the saw disk and makes the support block abut against the saw frame block, there is a gap between the transverse insert piece and the saw disk. During the actual operation of sawing the steel plate, the operator may have the following operation errors that cause damage to the transverse insert piece. Specifically, during the process of the saw disk of the disk sawing machine sawing the steel plate, when the horizontal feeding position of the saw disk is not in place yet, the operator drives the transverse insert piece close to the saw disk (intending to insert the transverse insert piece into the saw slot), resulting in the transverse insert piece contacting the saw disk and being damaged by the saw disk sawing. To solve this problem, the first anti-error protection device specially set in this solution, during the process of the saw disk of the disk sawing machine sawing the steel plate, if the horizontal feeding position of the saw disk is not in place yet and the operator drives the transverse insert piece close to the saw disk, then the support block will abut against the saw frame block. At this time, there is a gap between the transverse insert piece and the saw disk, thus preventing the transverse insert piece from contacting the saw disk.

[0015] Preferably, it further includes a vertical saw slot maintaining device. The vertical saw slot maintaining device includes a vertical insert piece and an insert piece lifting mechanism for driving the vertical insert piece to lift and lower. When the insert piece lifting mechanism moves the vertical insert piece up to the highest position, the lowest point position on the vertical insert piece is higher than the highest point position on the saw disk. During the process of the saw disk of the disk sawing machine sawing the steel plate, the insert piece lifting mechanism drives the vertical insert piece to move downward and insert into the saw slot of the steel plate. In this way, the vertical insert piece can cooperate with the transverse insert piece to further maintain the width of the saw slot, thereby further effectively avoiding the problem that during the sawing process of the steel plate, due to the shrinkage of the saw slot, it affects the rotary sawing movement of the saw disk and even causes the saw disk to be stuck.

[0016] Preferably, it further includes a second anti-misoperation protection device. The vertical saw slot holding device further includes a lifting support seat. The vertical insert is fixed on the lifting support seat. There are two saw frame limit blocks, left and right, on the frame. The saw frame is located between the two saw frame limit blocks. The second anti-misoperation protection device includes a transverse bar provided on the saw frame and parallel to the transverse movement track. The transverse bar is located above the saw disk, and the length of the transverse bar is greater than the diameter of the saw disk.

[0017] When the insert lifting mechanism moves the vertical insert to the highest position and the saw frame abuts against the left saw frame limit block, the transverse bar is located below the lifting support seat to block the downward movement of the lifting support seat.

[0018] During the actual operation of steel plate sawing, the operator may make the following operation mistakes, resulting in the problem of damage to the vertical insert. Specifically, during the process of the saw disk of the circular sawing machine sawing the steel plate, the horizontal feeding position of the saw disk is not in place yet (the saw disk has not cut a saw slot in the steel plate directly below the vertical insert), and the operator drives the vertical insert to move downward, resulting in the problem of "the vertical insert colliding with the steel plate" or "the vertical insert contacting the saw disk", which causes damage to the vertical insert. To solve this problem, the second anti-misoperation protection device is specially set in this solution. Specifically, when the horizontal feeding position of the saw disk is not in place yet (the saw disk has not cut a saw slot in the steel plate directly below the vertical insert), if the operator drives the vertical insert to move downward, the lifting support seat will abut against the transverse bar, and the transverse bar will block the downward movement of the lifting support seat and the vertical insert, thus avoiding "the vertical insert contacting the saw disk" or "the vertical insert colliding with the steel plate".

[0019] Preferably, the frame includes a bottom frame and a gantry frame provided on the bottom frame. The gantry frame includes a top beam and two support frames, left and right. The transverse movement track is provided on the top beam.

[0020] Preferably, the saw disk rotation driving mechanism includes a saw disk driving motor provided at the top of the feeding frame. The saw disk driving motor is located above the top beam. This is beneficial to the layout of the saw disk driving motor and is beneficial to supporting the saw disk driving motor through the gantry frame.

[0021] Preferably, the transverse movement track includes an upper transverse movement guide rail and a lower transverse movement guide rail. In this way, it is beneficial to improve the movement stability of the saw frame.

[0022] Preferably, the steel plate clamping mechanism includes a movable clamping block, a fixed clamping block provided on the feeding frame, and a movable clamping block translation mechanism for driving the movable clamping block to approach or move away from the fixed clamping block. The moving direction of the movable clamping block is perpendicular to the longitudinal movement track.

[0023] Preferably, the steel plate feeding device further includes a roller path provided on the feeding rack, and the conveying direction of the roller path is parallel to the longitudinal movement track. In this way, the steel plate on the steel plate feeding device will be supported on the roller path, which is beneficial to adjusting the position of the steel plate on the steel plate feeding device.

[0024] The beneficial effects of the present invention are as follows:

[0025] Firstly, it is not only convenient for feeding, but also can effectively avoid the problem that the vibration of the material plate is likely to occur during the sawing process of the steel plate, which affects the sawing quality.

[0026] Secondly, it can effectively avoid the problem that during the sawing process of the steel plate, due to the shrinkage of the saw kerf, the rotary sawing movement of the saw disk is affected, and even the saw disk is stuck. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0044] Specific embodiment 1: As Figure 1 , Figure 2 , Figure 3 shown, a circular sawing machine includes a machine frame 1, a sawing device 5, a steel plate feeding device 6 and a steel plate pressing device 4. A processing plane 1.0 is provided on the machine frame, and the processing plane is used for placing the steel plate to be sawn.

[0045] The sawing device 5 includes a transverse moving track 5.1 provided on the machine frame, a saw frame 5.2 moving along the transverse moving track, a saw frame reciprocating moving mechanism for driving the saw frame to move, a saw blade 5.3 rotatably provided on the saw frame, and a saw blade rotation driving mechanism provided on the saw frame for driving the saw blade to rotate. In this embodiment, the transverse moving track is horizontally distributed.

[0046] The steel plate feeding device 6 is used to feed the steel plate to be cut onto the processing plane. The steel plate feeding device includes a longitudinal moving track 6.1 provided on the machine frame, a feeding frame 6.2 moving along the longitudinal moving track, a feeding frame reciprocating moving mechanism for driving the feeding frame to move, and a steel plate clamping mechanism 6.4 provided on the feeding frame. The longitudinal moving track is perpendicular to the transverse moving track. In this embodiment, the longitudinal moving track is horizontally distributed.

[0047] The steel plate pressing device is used to press the steel plate on the processing plane. The steel plate pressing device includes a pressing block 4.1 located above the processing plane and a pressing block lifting mechanism 4.2 for driving the pressing block to lift. In this embodiment, there are multiple pressing blocks, and the pressing blocks are sequentially distributed along the transverse moving track direction. The pressing block lifting mechanism corresponds to each pressing block, and the pressing block lifting mechanism is used to lift the corresponding pressing block.

[0048] The specific operation of the disk sawing machine in this embodiment is as follows.

[0049] First, as Figure 5 shown, the steel plate 9 to be cut is placed on the feeding rack by a crane or a forklift and clamped and fixed by the steel plate clamping mechanism. Then, the feeding rack and the steel plate to be cut are fed into the automatic position on the processing plane by the reciprocating movement mechanism of the feeding rack, so as to realize the automatic feeding of the steel plate to be cut through the steel plate feeding device, which is convenient for feeding.

[0050] Second, the steel plate is pressed and fixed on the processing plane by the steel plate pressing device.

[0051] Third, the saw disk is driven to rotate by the saw disk rotation driving mechanism, and the saw frame and the saw disk are driven to make a feeding motion by the saw frame reciprocating movement mechanism, so as to radially saw the steel plate on the processing plane. Since the steel plate pressing device presses and fixes the steel plate on the processing plane, during the sawing process of the steel plate, the problem that the vibration of the material plate is likely to occur during the sawing process of the steel plate and affect the sawing quality can be effectively avoided.

[0052] Specifically, the machine frame includes a bottom frame 1.1 and a gantry frame 1.2 arranged on the bottom frame. The gantry frame includes a top beam 1.21 and two left and right support frames. The transverse movement track is arranged on the top beam. In this embodiment, the transverse movement track includes an upper transverse guide rail and a lower transverse guide rail. In this way, it is beneficial to improve the movement stability of the saw frame.

[0053] The saw disk rotation driving mechanism includes a saw disk driving motor 5.4 arranged on the top of the feeding rack, and the saw disk driving motor is located above the top beam. The saw disk driving motor is used to drive the saw disk to rotate. The saw frame reciprocating movement mechanism is a linear slide table, and the saw frame is connected with the slider of the linear slide table. Of course, the saw frame reciprocating movement mechanism can also be other reciprocating movement mechanisms such as an electric cylinder.

[0054] The feeding rack reciprocating movement mechanism is a linear slide table, and the feeding rack is connected with the slider of the linear slide table. Of course, the feeding rack reciprocating movement mechanism can also be other reciprocating movement mechanisms such as an electric cylinder.

[0055] The pressing block lifting mechanism is a cylinder or an oil cylinder or an electric cylinder.

[0056] The steel plate clamping mechanism 6.4 includes a moving clamping block 6.42, a fixed clamping block 6.41 arranged on the feeding rack, and a moving clamping block translation mechanism for driving the moving clamping block to approach or move away from the fixed clamping block. The moving direction of the moving clamping block is perpendicular to the longitudinal movement track. The moving direction of the moving clamping block is horizontally distributed. The moving clamping block translation mechanism is an oil cylinder or an electric cylinder.

[0057] In this embodiment, the steel plate feeding device further includes a roller path 6.3 arranged on the feeding rack, and the conveying direction of the roller path is parallel to the longitudinal movement track. In this way, when a crane or a forklift places the steel plate to be cut on the feeding rack, the steel plate will be supported on the roller path, which is beneficial to adjusting the position of the steel plate on the steel plate feeding device, and after the position of the steel plate is adjusted, it is clamped and fixed by the steel plate clamping mechanism.

[0058] Specific embodiment two, the rest of the structure of this embodiment refers to specific embodiment one, and the difference is as follows:

[0059] As Figure 1 , Figure 2 , Figure 4 , Figure 5 shown, a circular sawing machine further includes a transverse saw seam maintaining device 2, and the transverse saw seam maintaining device includes a transverse insert 2.1 and an insert reciprocating movement mechanism 2.2 for driving the transverse insert to move. The moving direction of the transverse insert is parallel to the transverse movement track, and the transverse insert is located on one side of the saw disc. The transverse insert is vertically distributed. In this embodiment, the transverse insert is parallel to the transverse movement track, and the transverse inserts are distributed on the left side of the saw disc. The insert reciprocating movement mechanism is a cylinder or an oil cylinder or an electric cylinder. During the process of the saw disc of the circular sawing machine sawing the steel plate, the insert reciprocating movement mechanism drives the transverse insert to insert into the saw seam of the steel plate.

[0060] In this embodiment, the transverse saw seam maintaining device further includes a transverse movement support 2.3, and the transverse insert is fixed on the transverse movement support. The cylinder or the oil cylinder or the electric cylinder constituting the insert reciprocating movement mechanism is connected to the transverse movement support for driving the transverse movement support to move.

[0061] Furthermore, a circular sawing machine further includes a vertical saw seam maintaining device 3. The vertical saw seam maintaining device includes a vertical insert 3.1 and an insert lifting mechanism 3.3 for driving the vertical insert to lift. The vertical insert is vertically distributed. In this embodiment, the vertical insert is parallel to the transverse movement track. The insert lifting mechanism is a cylinder or an oil cylinder or an electric cylinder. When the insert lifting mechanism lifts the vertical insert to the highest position, the lowest point position on the vertical insert is higher than the highest point position on the saw disc. In this way, during the process of the saw frame reciprocating movement mechanism driving the saw disc to feed from left to right, interference between the saw disc and the vertical insert can be avoided. During the process of the saw disc of the circular sawing machine sawing the steel plate, the insert lifting mechanism drives the vertical insert to move downward and insert into the saw seam of the steel plate.

[0062] In this embodiment, the vertical saw seam maintaining device further includes a lifting support 3.2, a vertical guide sleeve arranged on the frame, and a vertical guide rod 3.4 cooperating with the vertical guide sleeve. The vertical insert is fixed on the lifting support, and the lower end of the vertical guide rod is connected to the lifting support. The cylinder or the oil cylinder or the electric cylinder constituting the insert lifting mechanism is connected to the lifting support for driving the lifting support to lift.

[0063] There are two vertical inserts, and the two vertical inserts are distributed in sequence along the direction of the transverse movement track. The insert lifting mechanism corresponds to the vertical insert one by one, and the insert lifting mechanism is used to lift and lower the corresponding vertical insert.

[0064] In this embodiment, during the process of the saw blade of the disk sawing machine sawing the steel plate, the saw frame reciprocating movement mechanism drives the saw blade to feed from left to right (saw the steel plate from left to right). When the saw blade feeds to the first specified position to form a saw kerf on the left side of the steel plate, the insert reciprocating movement mechanism drives the transverse insert to insert into the saw kerf of the steel plate; in this way, the width of the saw kerf can be maintained, effectively avoiding the problem that during the sawing process of the steel plate, due to the shrinkage of the saw kerf, it affects the rotary sawing movement of the saw blade, and even causes the saw blade to be stuck.

[0065] Then, the saw blade continues to feed to the right. When the saw blade feeds to the second specified position and a saw kerf has been sawn on the steel plate directly below the vertical insert, the insert lifting mechanism drives the vertical insert to move downward and insert into the saw kerf of the steel plate. In this way, the vertical insert can cooperate with the transverse insert to further maintain the width of the saw kerf, thereby further effectively avoiding the problem that during the sawing process of the steel plate, due to the shrinkage of the saw kerf, it affects the rotary sawing movement of the saw blade, and even causes the saw blade to be stuck.

[0066] Then, when the saw blade saws through the steel plate, the insert reciprocating movement mechanism drives the transverse insert to move leftward to reset, and the insert lifting mechanism drives the vertical insert to move upward to reset; then the saw frame reciprocating movement mechanism drives the saw blade to move leftward to reset.

[0067] In this embodiment, there are two vertical inserts, and the two vertical inserts are distributed in sequence along the direction of the transverse movement track.

[0068] Specific Embodiment 3, the rest of the structure of this embodiment refers to Specific Embodiment 2, and the difference lies in:

[0069] Such as Figure 6 、 Figure 7As shown in the figure, a circular sawing machine further includes a first anti-misoperation protection device 7. The first anti-misoperation protection device includes a support block 7.1 fixed on the transverse support and a saw frame block 7.2 arranged at the bottom of the saw frame for cooperating with the support block. The saw frame block and the support block are arranged in sequence along the transverse track direction. The saw frame block is located between the support block and the saw disc. When the insert reciprocating mechanism drives the transverse insert to move towards the saw disc and makes the support block abut against the saw frame block, there is a gap between the transverse insert and the saw disc. During the actual operation of steel plate sawing, the operator may have the following operation errors that cause damage to the transverse insert. Specifically, during the process of the saw disc of the circular sawing machine sawing the steel plate, when the horizontal feeding position of the saw disc is not in place, the operator drives the transverse insert close to the saw disc (intending to insert the transverse insert into the saw kerf), resulting in contact between the transverse insert and the saw disc and being damaged by the saw disc. To solve this problem, the first anti-misoperation protection device specially set in this solution is such that during the process of the saw disc of the circular sawing machine sawing the steel plate, if the horizontal feeding position of the saw disc is not in place and the operator drives the transverse insert close to the saw disc, the support block will abut against the saw frame block. At this time, there is a gap between the transverse insert and the saw disc, thus preventing the transverse insert from contacting the saw disc.

[0070] Furthermore, as Figure 6 , Figure 7 shown in the figure, a circular sawing machine further includes a second anti-misoperation protection device 8. There are two saw frame limit blocks, left and right, provided on the machine frame. The saw frame is located between the two saw frame limit blocks, left and right. The second anti-misoperation protection device includes a transverse bar 8.1 arranged on the saw frame and parallel to the transverse track. The transverse bar is located above the saw disc 5.3, and the length of the transverse bar is greater than the diameter of the saw disc. In this embodiment, the projection of the saw disc in the vertical direction completely falls within the projection of the transverse bar in the vertical direction. When the insert lifting mechanism moves the vertical insert to the highest position and the saw frame abuts against the left saw frame limit block, the transverse bar is located below the lifting support and is used to block the downward movement of the lifting support.

[0071] In the actual operation of steel plate sawing, the operator may make the following operation mistakes, which may cause damage to the vertical insert. Specifically, during the process of the saw blade of the circular sawing machine sawing the steel plate, when the position of the saw blade feeding to the right is not in place (the saw blade has not cut a saw slot on the steel plate directly below the vertical insert), the operator drives the vertical insert to move downward, resulting in the problem of "the vertical insert colliding with the steel plate" or "the vertical insert contacting the saw blade", which causes damage to the vertical insert. To solve this problem, the second anti-misoperation protection device is specifically set in this solution. Specifically, when the saw frame reciprocating movement mechanism drives the saw blade to feed from left to right (sawing the steel plate from left to right), when the saw blade has not fed to the specified position to the right (that is, the saw blade has not cut a saw slot on the steel plate directly below the vertical insert), if the operator drives the vertical insert to move downward, the lifting support will abut against the horizontal bar, and the horizontal bar will block the downward movement of the lifting support and the vertical insert, thus avoiding "the vertical insert contacting the saw blade" or "the vertical insert colliding with the steel plate".

[0072] Further, as Figure 6 , Figure 7 shown, the second anti-misoperation protection device further includes a torsion spring, an anti-misoperation blocking rod 8.2 rotatably arranged on the frame through a shaft rod 8.4, a limit block arranged on the frame, and a top rod 8.3 arranged at the upper end of the vertical guide rod. The shaft rod is parallel to the transverse track, and the anti-misoperation blocking rod is perpendicular to the transverse track. The limit block is provided with a blocking rod slot 8.5 for cooperating with the anti-misoperation blocking rod upward, and the opening of the blocking rod slot faces upward. One end of the blocking rod slot facing the shaft rod is open. The torsion spring is used to provide an elastic force to make the anti-misoperation blocking rod rotate downward around the shaft rod. In this embodiment, the anti-misoperation blocking rod is located on the right side of the vertical saw slot holding device.

[0073] As Figure 7 shown, during the process of the insert lifting mechanism driving the vertical insert to descend, the anti-misoperation blocking rod will rotate downward around the shaft rod under the action of the torsion spring until the end of the anti-misoperation blocking rod enters the blocking rod slot and abuts against the bottom surface of the blocking rod slot. At this time, the anti-misoperation blocking rod is located on the moving track of the saw frame. When the saw frame moves along the transverse track to the anti-misoperation blocking rod, the saw frame will be blocked by the anti-misoperation blocking rod.

[0074] During the process of the insert lifting mechanism driving the vertical insert to ascend, the top rod will abut against the anti-misoperation blocking rod and push the anti-misoperation blocking rod to rotate upward around the shaft rod so that the saw frame can move along the transverse track without being blocked by the anti-misoperation blocking rod.

[0075] After the saw blade cuts through the steel plate, the vertical insert needs to be lifted upward and reset by the insert lifting mechanism before the saw frame reciprocating movement mechanism can drive the saw blade to move leftward and reset; otherwise, the saw blade will collide with the vertical insert. In actual operation, the operator may drive the saw blade to move leftward and reset before the vertical insert has been lifted upward and reset, resulting in the problem that the saw blade will collide with the vertical insert. To solve this problem, in the embodiment, an anti-misoperation blocking rod is provided on the second anti-misoperation protection device. Specifically,

[0076] After the saw blade cuts through the steel plate, if the operator operates normally, first drive the vertical insert to move upward and reset through the insert lifting mechanism. During this process, the ejector rod will abut against the anti-misoperation blocking rod and push the anti-misoperation blocking rod to rotate upward around the shaft rod, so that the saw frame can move along the transverse movement track without being blocked by the anti-misoperation blocking rod; then, the saw frame reciprocating movement mechanism can drive the saw blade to move leftward and reset without being affected.

[0077] After the saw blade cuts through the steel plate, if the operator drives the saw blade to move leftward and reset before the vertical insert has been lifted upward and reset, then at this time, the anti-misoperation blocking rod will rotate downward around the shaft rod under the action of the torsion spring and abut against the bottom surface of the blocking rod slot. The anti-misoperation blocking rod is located on the movement track of the saw frame. When the saw frame moves along the transverse movement track to the anti-misoperation blocking rod, the saw frame will be blocked by the anti-misoperation blocking rod.

[0078] During the process of the insert lifting mechanism driving the vertical insert to descend, the anti-misoperation blocking rod will rotate downward around the shaft rod under the action of the torsion spring until the end of the anti-misoperation blocking rod enters the blocking rod slot and abuts against the bottom surface of the blocking rod slot. At this time, the anti-misoperation blocking rod is located on the movement track of the saw frame. When the saw frame moves along the transverse movement track to the anti-misoperation blocking rod, the saw frame will be blocked by the anti-misoperation blocking rod, thus avoiding the problem of the saw blade colliding with the vertical insert.

[0079] The above are only the preferred embodiments of the present invention, and do not impose any limitations on the present invention. Any simple modifications, changes, and equivalent transformations made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
