Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of light steel keel cutting, in particular to a cutting device for light steel keel production. BACKGROUND

[0002] Light steel keel is widely used in the construction of ceiling, partition and other structures due to its advantages of light weight, high strength and convenient installation. In the production process of light steel keel, it is necessary to cut the long strip-shaped light steel keel into segments of a specific length according to actual construction requirements.

[0003] Currently, there are two traditional methods for cutting light steel keel: one is keel cutter cutting, which cuts the light steel keel by the instantaneous impact force of the cutter. However, since the light steel keel is mostly thin-walled metal profile, the extrusion cutting of the cutter is easy to cause obvious plastic deformation of the cut surface of the keel, and the edge of the cut surface is easy to form irregular burrs, which not only affects the appearance quality, but also may scratch the construction personnel in the subsequent installation process. Meanwhile, the deformed cut surface will cause gaps when the keel is spliced, reducing the overall structure. The other is cutting saw cutting, which realizes cutting by the contact between the high-speed rotating saw blade and the light steel keel. However, the high-speed friction between the saw blade and the cutting part of the keel will generate a lot of heat, which is easy to cause thermal deformation of the metal material in the cutting area of the light steel keel, resulting in a decrease in the local structural strength of the keel. In addition, the saw blade cutting is also easy to produce fine metal burrs on the cut surface, which requires additional polishing process to remove the burrs, increasing the production time and cost.

[0004] With the continuous improvement of the precision requirements of fabricated buildings on components, the burr and deformation problems existing in the traditional cutting method have been difficult to meet the production needs of high-quality light steel keel, and a new cutting method is urgently needed to effectively avoid the burr and deformation problems after cutting the light steel keel. SUMMARY

[0005] To overcome the above-mentioned defects, the embodiments of the present application provide a cutting device for light steel keel production, which solves the technical problem that burrs and deformation occur at the cutting part of the light steel keel after cutting.

[0013] Optionally, the insertion block has a first guide inclined surface arranged near the opening edge of the insertion slot. The first guide inclined surface is used to guide the end of the inner recess segment into the insertion slot. The insertion block also has a second guide inclined surface near the outer peripheral edge. The second guide inclined surface is used to guide the light steel keel to slide onto the outer wall of the insertion block.

[0014] Optionally, two discs are arranged on the sliding seat and rotate. A through hole is formed in the middle of each disc. The through hole is in communication with the containing space. The through hole is used to pass the light steel keel and the support rod. A plurality of pressing members are arranged on the disc. The pressing members are used to press against the outer wall of the light steel keel entering the through hole. The disc can rotate synchronously with the rotary clamp by the pressing action of the pressing members and the light steel keel.

[0015] Optionally, a plurality of telescopic members are arranged on the wall of the sliding seat. The movable end of the telescopic member extends into the containing space and corresponds to the cutting knife. The telescopic member is used to make the cutting knife tightly press against the outer wall of the light steel keel.

[0016] Optionally, it further comprises:

[0017] A track seat is arranged on the bearing platform.

[0018] The mounting base is slidably arranged on the track base, the rotating clamp is rotatably arranged on the mounting base, the track base is provided with a recessed groove, and the bottom of the mounting base is provided with two groups of wheels; when the mounting base drives the inner recessed section to be separated from the cutting knife, one group of wheels of the mounting base is slid into the recessed groove, and the mounting base can drive the supporting rod to be raised upward with the other group of wheels as the shaft to break the part of the light steel keel which is not cut open from the cutting position.

[0019] Optionally, the track base is provided with a fixing plate away from one side of the mounting base, the fixing plate is provided with a hydraulic rod, the movable end of the hydraulic rod is hingedly connected with a connecting rod, one end of the connecting rod away from the hydraulic rod is hingedly connected with the mounting base, and the hydraulic rod is used for pushing and pulling the mounting base so that the mounting base enters or slides out of the recessed groove.

[0020] Optionally, the track base is further provided with a filling block, the filling block is used for filling the recessed groove, the filling block is located behind the recessed groove, and the top surface of the track base is a plane.

[0021] Optionally, the bearing platform is provided with a tooth-shaped guide rail, and the bottom of the sliding base is rotatably provided with a driving gear which is engaged with the tooth-shaped guide rail so that the sliding base slides along the bearing platform.

[0022] The present application has the following beneficial effects:

[0023] In the present application, when cutting a whole light steel keel, first, the light steel keel to be cut is placed on the supporting rod so that the light steel keel is buckled on the supporting rod, then the end of the light steel keel away from the rotating clamp is aligned with the end of the supporting rod, and the other end of the light steel keel is placed into the rotating clamp and clamped and fixed by the rotating clamp; then the supporting rod drives the light steel keel to be cut to gradually enter the accommodating space of the sliding base; when the light steel keel reaches the specified position, the cutting knife is adjusted to move radially so that the cutting knife is pressed against the outer peripheral wall of the light steel keel; then the rotating clamp is driven to rotate, the rotating clamp drives the clamped light steel keel to rotate synchronously, and the rotating light steel keel cooperates with the cutting knife in the pressing state to gradually cut the light steel keel along the circumference of the light steel keel, thereby completing the preliminary cutting operation.

[0024] Compared to traditional keel cutting, which easily leads to plastic deformation and irregular burrs on the cross-section, and cutting saws, which easily cause thermal deformation, reduce keel strength, and require additional grinding to remove burrs, this device uses a slicing blade to cut along the circumference of the light steel keel. This eliminates the need for compression or high-speed friction, preventing plastic deformation of the cut surface and avoiding irregular burrs. This prevents injuries to construction workers during subsequent installation and ensures seamless keel splicing, improving structural integrity. Furthermore, the slicing process generates no significant heat, preventing thermal deformation of the metal material in the cut area and ensuring that the local structural strength of the keel remains unaffected. This eliminates the need for additional grinding, reducing production time and costs. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0040] like Figures 1 to 7 The diagram illustrates a cutting device for producing light steel keel according to an embodiment of the present invention. The device is used to cut light steel keel into segments. The cutting device includes a support platform 1, a rotating clamp 2, a support rod 3, a sliding seat 4, and a slicing blade 5. Specifically, the rotating clamp 2 is rotatably mounted on the support platform 1. The rotating clamp 2 includes a C-shaped frame, a first hydraulic push rod 18, and a second hydraulic push rod 19 mounted on the frame. The first hydraulic push rod 18 is used to push the second hydraulic push rod 19 laterally. The movable end of the second hydraulic push rod 19 is used to press the light steel keel. One end of the support rod 3 is located inside the rotating clamp 2, and the other end extends to the outside of the rotating clamp 2. The outer peripheral wall of the support rod 3 can fit against the inner wall of the light steel keel, serving to support and receive the light steel keel to be cut. When the light steel keel is placed on the support rod 3, the rotating clamp 2 is used to clamp the light steel keel to be cut. The sliding seat 4 is located on one side of the mounting base 11, and is arranged opposite to the mounting base 11. The sliding seat 4 has an internal receiving space, into which the support rod 3 can enter. Several slicing blades 5 are arranged circumferentially on the inner wall of the sliding seat 4, and the slicing blades 5 can press against the outer peripheral wall of the light steel keel that enters the receiving space. Specifically, after the support rod 3 drives the light steel keel to be cut into the receiving space, the slicing blades 5 press against the outer peripheral wall of the light steel keel to be cut. The light steel keel can rotate under the action of the clamp. The rotating light steel keel cooperates with the pressing slicing blades 5, so that the slicing blades 5 cut the light steel keel along the peripheral wall of the light steel keel.

[0041] In the above scheme, when cutting a whole light steel keel, firstly, the light steel keel to be cut is placed on the support rod 3, so that the light steel keel is fastened to the support rod 3. Then, the end of the light steel keel away from the rotating clamp 2 is aligned with the end of the support rod 3, and the other end of the light steel keel is placed into the rotating clamp 2, and clamped and fixed by the rotating clamp 2. Then, the support rod 3 drives the light steel keel to be cut to gradually enter the receiving space of the sliding seat 4. When the light steel keel reaches the designated position, the slicing blade 5 is adjusted to move radially, so that the slicing blade 5 presses against the outer peripheral wall of the light steel keel. Then, the rotating clamp 2 is driven to rotate, and the rotating clamp 2 drives the clamped light steel keel to rotate synchronously. The rotating light steel keel and the slicing blade 5 in the pressing state cooperate with each other, and the slicing blade 5 gradually cuts the light steel keel along the circumference of the light steel keel, completing the preliminary cutting operation.

[0042] Compared to traditional keel cutting, which easily leads to plastic deformation of the cross-section and irregular burrs, and cutting saws, which easily cause thermal deformation, reduce keel strength, and require additional grinding to remove burrs, this device uses a slicing blade 5 to slice along the circumference of the light steel keel. Without squeezing or high-speed friction, it does not cause plastic deformation of the cut surface of the light steel keel, nor does it form irregular burrs, avoiding scratches to construction workers during subsequent installation. At the same time, it ensures seamless splicing of the keel and improves the overall structural integrity. Moreover, the slicing process does not generate a lot of heat, so it will not cause thermal deformation of the metal material in the cut area of ​​the light steel keel, ensuring that the local structural strength of the keel is not affected. There is no need to add an additional grinding process, reducing production time and production costs.

[0043] Furthermore, the support rod 3 has a concave section 302 and a support section 301. The concave section 302 is located at the end of the support section 301 away from the rotating clamp 2. The support section 301 is used to support the light steel keel, and the concave section 302 is used to reserve cutting space for the slicing blade 5 so that the blade of the slicing blade 5 can penetrate the side wall of the light steel keel. Alternatively, the concave section 302 can slide into the support section 301, and the extension and retraction of the concave section 302 can be controlled by the third hydraulic push rod 20 to adjust the extension length of the concave section 302.

[0044] For example, such as Figure 4 As shown, in the above scheme, the light steel keel to be cut is fitted onto the support rod 3, so that the inner wall of the light steel keel fits against the support section 301 of the support rod 3, and the support section 301 provides support and fixation for the light steel keel; the light steel keel enters the receiving space of the sliding seat 4, and the slicing blade 5 presses against the outer peripheral wall of the light steel keel; when the light steel keel rotates and cooperates with the slicing blade 5 to slice, since the support rod 3 has a concave section 302, the slicing blade 5 will not be blocked by the support rod 3 during the slicing process, and the blade can smoothly penetrate the side wall of the light steel keel to complete the full circumferential slicing of the light steel keel.

[0045] The concave section 302 of the support rod 3 provides ample cutting space for the slicing blade 5, effectively preventing the slicing blade 5 from being unable to penetrate the side wall of the light steel keel due to obstruction by the support rod 3. This ensures that the slicing blade 5 can completely cut the circumferential side wall of the light steel keel, reducing the difficulty of subsequent breaking operations. At the same time, the stable support of the support section 301 for the light steel keel can prevent the light steel keel from shifting during the slicing process, further ensuring the flatness of the cut surface and eliminating burrs and deformation problems.

[0046] Furthermore, a sliding seat 4 is provided with an insert 6 on the side away from the rotating clamp 2. The insert 6 has a slot 601, the opening of which faces the receiving space. After the sliding seat 4 moves towards the rotating clamp 2, the end of the concave section 302 can be inserted into the slot 601, so that the inner wall of the light steel keel on the concave section 302 abuts against the outer wall of the insert 6. The outer edge of each corner of the insert 6 includes two parts: a first guide slope extending upward for guiding the light steel keel, and a second guide slope extending inward into the slot 601 for guiding the light steel keel. The two guide slopes are an integral structure. The first guide slope and the second guide slope are used to guide the end face of the concave section 302 into the slot 601 and to guide the light steel keel to slide onto the outer peripheral wall of the insert 6, respectively.

[0047] The cross-sectional shape of the insert 6 is the same as that of the support section 301, and the opening shape of the slot 601 is the same as that of the concave section 302. It can be understood that, because the light steel keel itself has a certain rigidity, when the support rod 3 carries the light steel keel and inserts into the insert 6, the concave section 302 of the support rod 3 can be inserted into the slot 601 under the action of the first guide slope, while the light steel keel is inserted into the outer peripheral wall of the insert 6 under the action of the second guide slope.

[0048] like Figure 1 As shown, a disc 7 is provided on both ends of the sliding seat 4. A through hole is provided in the middle of the disc 7, which is connected to the receiving space of the sliding seat 4. The light steel keel can enter the receiving space through the through hole. Several pressing parts 8 are provided on the disc 7. The pressing parts 8 are used to press against the outside of the light steel keel. The disc 7 can rotate synchronously with the rotating clamp 2 with the pressing action of the pressing parts 8 and the light steel keel.

[0049] In the above scheme, the light steel keel passes sequentially through the through hole of the disc 7 near the rotating clamp 2, the receiving space of the sliding seat 4, and the through hole of the disc 7 away from the rotating clamp 2. After the light steel keel is inserted into the insert block 6, the pressing member 8 abuts against the outer wall of the light steel keel. The main function of the pressing member 8 is that when the support rod 3 rotates, it can drive the disc 7 to rotate synchronously under the action of the pressing member 8. The pressing member 8 consists of an adjusting seat and a pressing roller. The adjusting seat is set on the disc 7 and can adjust its position and angle. The pressing roller is rotatably set on the movable end of the adjusting seat. Under the drive of the adjusting seat, the pressing roller can contact the outer wall of the light steel keel.

[0050] In the above scheme, according to the specifications of the light steel keel, the position and angle of the adjusting seat on the disc 7 are adjusted so that the pressure roller at the movable end of the adjusting seat is aligned with the outer wall of the light steel keel; then the adjusting seat is operated to push the pressure roller to move radially until the pressure roller contacts the outer wall of the light steel keel; when the light steel keel moves under the drive of the rotating clamp 2, the pressure roller rotates under the action of friction, always maintaining the pressure state on the light steel keel, and completing the slicing operation in conjunction with the hydraulic telescopic component 9 and the slicing blade 5.

[0051] For example, such as Figure 5 As shown, the mounting base 11 is equipped with several telescopic components 9. The movable ends of the telescopic components 9 extend into the receiving space of the sliding base 4, and each telescopic component 9 corresponds to a dicing blade 5. The telescopic components 9 can push the dicing blade 5 against the outer peripheral wall of the light steel keel through their own telescopic movement. The dicing blade 5 is arc-shaped to facilitate cutting the light steel keel. It can be understood that because the cross-section of the light steel keel is rectangular, the telescopic components 9 are dynamically telescopic according to the cutting needs. For example, the telescopic components 9 can be electric push rods or hydraulic rods 13, which are controlled in real time by a controller. Alternatively, spring rods can be used, that is, the spring rods apply a force to the dicing blade 5 to press against the light steel keel. When spring rods are used, and there is no light steel keel in the receiving space, the spring rods will move closer together, hindering the support rod 3 and the light steel keel from entering the receiving space. Therefore, when using spring rods, it is necessary to manually release and pull back the spring rods to reset them.

[0052] In the above scheme, during the cutting process, the support rod 3 drives the light steel keel to rotate, and the slicing blade 5 slices along the circumference of the light steel keel so that the slicing blade 5 slices the light steel keel with appropriate pressure. The telescopic component 9 controls the clamping force of the slicing blade 5 against the light steel keel, which can be flexibly adjusted according to different specifications of light steel keels to avoid incomplete slicing due to insufficient clamping force or local deformation of the light steel keel due to excessive force. The hydraulic drive method is stable and reliable, which can ensure that the clamping force of each slicing blade 5 is uniform and consistent, so that the circumferential slicing depth of the light steel keel is the same, the cutting surface is flat, and the cutting quality is further improved. At the same time, it expands the applicability of the device to different types of light steel keels.

[0053] For example, such as Figure 6As shown, a track seat 10 is provided on the support platform 1, and a sliding seat 4 is slidably disposed on the side of the support platform 1 away from the track seat 10. The track seat 10 has a recessed groove 1001, which is a semi-circular groove. The track seat 10 is disposed on the support platform 1, and the mounting seat 11 is slidably disposed on the track seat 10. The bottom of the mounting seat 11 has two sets of wheels. When the mounting seat 11 drives the concave section 302 to disengage from the cutting blade 5, one set of wheels of the mounting seat 11 slides into the recessed groove 1001. The mounting seat 11 can then use the other set of wheels as an axle to drive the support rod 3 upwards, thereby breaking off the uncut portion of the light steel keel from the cutting position.

[0054] In the above scheme, after the circumferential cutting of the light steel keel is completed, the mounting base 11 is pushed to slide backward along the track base 10. At this time, due to the insertion of the light steel keel and the insert block 6, the section of the light steel keel that is cut and inserted into the insert block 6 will not move, while the other section of the light steel keel still has some parts that have not been cut. Then the rotating clamp 2 releases the end of the light steel keel that is clamped, and then the support rod 3 moves backward with the rotating clamp 2. It should be noted that because the rotating clamp 2 will clamp an extra section of light steel keel when clamping, even if the support rod 3 moves backward, the rotating clamp 2 can still clamp the end of the light steel keel again. When the mounting base 11 moves backward, a set of wheels of the mounting base 11 will enter the recessed groove 1001. The mounting base 11 can drive the support rod 3 to tilt upward with the other set of wheels as the axle. Since the rotating clamp 2 and the support rod 3 are both set on the mounting base 11, when the mounting base 11 tilts upward, the support rod 3 will also tilt upward. At this time, the support rod 3 will drive the light steel keel located on the support rod 3 to tilt upward quickly. The part that has not been cut will be easily broken off. The uneven surface caused by repeated cutting is reduced by the above method.

[0055] Therefore, by adding a bearing platform 1, a track seat 10, and a recessed groove 1001, the uncut parts of the light steel keel can be broken without relying on additional cutting tools, avoiding the burrs and deformation problems that may be caused by secondary cutting; and the breaking process is achieved by the sliding of the mounting seat 11 and the lifting of the support rod 3, with uniform force, which will not cause new plastic deformation or burrs on the cross-section of the light steel keel, further ensuring the cutting quality; at the same time, the cutting process is simplified, eliminating the need for manual breaking and improving cutting efficiency.

[0056] For example, such as Figure 6 As shown, a fixing plate 12 is provided at the end of the track seat 10 away from the mounting seat 11. A hydraulic rod 13 is mounted on the fixing plate 12. A connecting rod 14 is hinged to the movable end of the hydraulic rod 13. The end of the connecting rod 14 away from the hydraulic rod 13 is hinged to the mounting seat 11. The hydraulic rod 13 can push and pull the mounting seat 11 through telescopic movement, causing the mounting seat 11 to enter or slide out of the recessed groove 1001 on the track seat 10.

[0057] In the above scheme, after the circumferential cutting of the light steel keel is completed, the hydraulic rod 13 on the fixed plate 12 is activated. The movable end of the hydraulic rod 13 retracts and pulls the mounting seat 11 along the track seat 10 towards the recessed groove 1001 through the hinged connecting rod 14. When one end of the mounting seat 11 slides into the recessed groove 1001, the mounting seat 11 gradually tilts upward under the action of the recessed groove 1001, driving the support rod 3 to tilt upward synchronously. The support rod 3 applies an upward force to the part of the light steel keel that has not been cut, breaking that part. After the cutting is completed, the movable end of the hydraulic rod 13 extends and pushes the mounting seat 11 along the track seat 10 out of the recessed groove 1001 through the connecting rod 14, returning to the initial position, ready for the next cutting operation.

[0058] The hydraulic rod 13 and connecting rod 14 work together to drive the mounting base 11 to slide and tilt, replacing manual operation and automating the breaking process, thus reducing the intensity of manual labor. The hydraulic drive method provides controllable force and smooth operation, and can precisely control the sliding speed and tilting angle of the mounting base 11, so that the uncut parts of the light steel keel are subjected to uniform force, avoiding the problem of cross-sectional deformation due to excessive force or failure to break smoothly due to insufficient force. At the same time, the automated operation improves cutting efficiency, ensures consistent breaking results each time, and improves the product qualification rate.

[0059] For example, such as Figure 1 As shown, a filler block 15 is also provided on the track seat 10. The shape of the filler block 15 matches the recessed groove 1001 on the track seat 10, and is used to fill the recessed groove 1001. When the filler block 15 is placed in the recessed groove 1001, the top surface of the track seat 10 forms a plane. It should be noted that the filler block 15 is also arc-shaped. The filler block 15 and the recessed groove 1001 are adapted to each other. An electric push rod is provided on the filler block 15. The electric push rod can pull the filler block 15 outward so that the filler block 15 can be removed from the recessed groove 1001.

[0060] In the above scheme, when performing the light steel keel cutting operation and without using the recessed groove 1001 for breaking, the filler block 15 is placed into the recessed groove 1001 of the track seat 10 to keep the top surface of the track seat 10 flat; at this time, the mounting seat 11 can slide freely along the flat top surface of the track seat 10 to adjust to a suitable cutting position; when the cutting is completed and the light steel keel needs to be broken, the filler block 15 is removed from the recessed groove 1001, and the mounting seat 11 is pushed to slide into the recessed groove 1001 to complete the breaking operation; after the breaking is completed, the filler block 15 is placed into the recessed groove 1001 again to restore the top surface of the track seat 10 to flatness, which facilitates the repositioning of the mounting seat 11 and subsequent operations.

[0061] The filler block 15 keeps the top surface of the track seat 10 flat when it is not broken, preventing the mounting seat 11 from getting stuck or shifting due to the presence of the recessed groove 1001 during the sliding process. This ensures smooth sliding of the mounting seat 11, reduces component wear, and extends the service life of the equipment. At the same time, the filler block 15 is easy to disassemble and install, does not affect the normal use of the recessed groove 1001, and balances the stability of the mounting seat 11 during the slicing operation with the convenience of the breaking operation, thereby improving the overall performance of the equipment.

[0062] For example, such as Figure 6 As shown, the rotary clamp 2 has a rotary driver, which is mounted on the mounting base 11. The movable end of the rotary driver is fixedly connected to the rotary clamp 2, and the rotary driver can drive the rotary clamp 2 to rotate around its own axis.

[0063] In the above scheme, the end of the light steel keel to be cut is placed in the rotating clamp 2 and clamped and fixed by the rotating clamp 2; then the rotating driver on the mounting base 11 is started, the movable end of the rotating driver drives the rotating clamp 2 to rotate, and the rotating clamp 2 in turn drives the light steel keel being held to rotate synchronously; while the light steel keel is rotating, the slicing blade 5 in the sliding seat 4 is adjusted so that it presses against the outer peripheral wall of the light steel keel, and the slicing blade 5 gradually slices the light steel keel along the circumference until the slicing operation is completed; according to the cutting requirements, the rotation speed of the clamp and the light steel keel can be controlled by adjusting the output speed of the rotating driver.

[0064] The rotary driver provides a stable power source for the rotary fixture 2, replacing manual rotation or other unstable driving methods. It can control the rotation speed and angle of the rotary fixture 2 and the light steel keel, ensuring that the cutting depth of the scriber 5 along the circumference of the light steel keel is uniform and consistent, avoiding problems such as uneven cut surfaces and burrs caused by unstable rotation speed. At the same time, the driving torque of the rotary driver is controllable, which can adapt to the rotation requirements of light steel keels of different specifications, improve the automation level and cutting accuracy of the device, and reduce human operation errors.

[0065] For example, such as Figure 7 As shown, a toothed guide rail 16 is provided on the bearing platform 1, and a drive gear 17 is rotatably provided at the bottom of the sliding seat 4. The drive gear 17 meshes with the toothed guide rail 16. By rotating the drive gear 17, the sliding seat 4 can be driven to slide along the toothed guide rail 16 of the bearing platform 1.

[0066] In the above scheme, according to the preset length of the light steel keel to be cut, the drive device at the bottom of the sliding seat 4 is activated, which drives the drive gear 17 to rotate. Since the drive gear 17 meshes with the toothed guide rail 16 on the bearing platform 1, the rotation of the drive gear 17 will drive the sliding seat 4 to move along the toothed guide rail 16. By controlling the rotation direction and number of rotations of the drive gear 17, the position of the sliding seat 4 on the bearing platform 1 is adjusted so that the slicing blade 5 in the sliding seat 4 is aligned with the preset cutting position of the light steel keel. After the position is adjusted, the rotation of the drive gear 17 is stopped, the position of the sliding seat 4 is fixed, and then the light steel keel slicing operation is carried out.

[0067] The meshing transmission between the toothed guide rail 16 and the drive gear 17 features high transmission accuracy and good stability. It can precisely control the movement distance and position of the sliding seat 4, ensuring that the dicing blade 5 can accurately align with the preset cutting position of the light steel keel, avoiding inaccurate cutting length due to position deviation, and improving product dimensional accuracy. At the same time, the meshing transmission is not prone to slippage, ensuring that the sliding seat 4 moves smoothly and reliably during the movement, reducing the impact of sliding seat 4 shaking on the dicing quality. Furthermore, the position of the sliding seat 4 can be precisely adjusted by controlling the rotation speed of the drive gear 17, adapting to the cutting needs of light steel keels of different lengths and enhancing the versatility of the device.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
