Description

Technical Field

[0001] This application relates to the field of flat steel laser cutting technology, specifically to a cutting device and method for processing stainless steel flat steel. Background Technology

[0002] Flat steel, as the name suggests, is a long strip of steel with a rectangular cross-section. Its specifications are expressed as "width × thickness". It is a very basic and extremely versatile profile, playing an important role in many industrial fields and daily life due to its ease of production, low cost, and ease of processing and installation.

[0003] Flat steel is made from strip steel through longitudinal shearing. When the flat steel is thin and narrow, it is usually transported by coiling. After being transported to the factory, the flat steel needs to be uncoiled and straightened. Then the straightened flat steel is transported to the laser cutting machine for cutting or punching.

[0004] Referring to publication number CN120115848A, entitled "A Laser Cutting Equipment and Method for Processing High-Strength Stainless Steel Flat Bars," this device uses a support plate and a pressure blade to press the flat bar material at the cutting position during the cutting process. The pressure blade is lifted when the plate passes through, causing it to compress the elastic force generated by the rubber pad, which pushes the pressure blade to press the flat bar material. By using the plane at the bottom of the pressure blade and the plane at the top of the support plate, the plate at the cutting position is kept in a flat state, avoiding bending and deformation of the thin flat bar during the conveying process, which would lead to incorrect cutting position.

[0005] Regarding the aforementioned technical solution, flat steel is cut into long and short strips. When cutting long strips of flat steel, the extended portion of the steel causes the clamping part of the laser cutting machine to tilt upwards under gravity, resulting in a slight deviation in the cutting path. The finished part may be longer or shorter than programmed, and the cut surface may exhibit a certain bevel (wider at the top and narrower at the bottom, or vice versa), failing to meet high-precision requirements. Summary of the Invention

[0006] In view of this, this application provides a cutting device for processing stainless steel flat bars, which aims to solve the problem that the cut surface will be oblique due to the lack of support at the cutting end when cutting flat bars.

[0007] Firstly, a cutting device for processing stainless steel flat bars adopts the following technical solution, including: This application provides a cutting device for processing stainless steel flat bars, which adopts the following technical solution: a placement frame and a moving mechanism mounted on the placement frame; the moving mechanism includes a cutting head capable of moving up and down and left and right on the placement frame; a connecting frame is fixedly connected to the side of the placement frame near the cutting head, a clamping seat is fixedly connected to the connecting frame, clamping blocks for clamping both sides of the flat bar are slidably connected to the side wall of the clamping seat, a support block for supporting the bottom of the flat bar is slidably connected to the clamping seat, and an abutment block for abutting the top of the flat bar is slidably connected to the clamping seat.

[0008] When the flat steel enters the processing area, the lateral clamping blocks clamp the material from both sides to prevent lateral displacement. The bottom support block rises to contact the bottom surface of the material, forming a stable support surface to counteract the effects of gravity. The top abutment block presses down simultaneously, forming a clamping force field perpendicular to the support block. The cutting head completes precise cutting under the drive of the moving mechanism, at which point the material maintains a stable posture under three-dimensional constraints.

[0009] This application effectively suppresses three-dimensional deformation during flat steel cutting, ensuring the geometric accuracy of the cutting path. The material maintains a stable spatial position during processing, and the perpendicularity of the cut surface is significantly improved, meeting the requirements of high-precision processing. The combined design of bottom support and top clamping successfully balances the torque generated by the material's own weight, preventing material warping during cutting.

[0010] Optionally, a push spring is fixedly connected to both the support block and the abutment block, and the push spring is used to push the support block and the abutment block to move toward a position close to the flat steel.

[0011] This application solves the problem of slit tilting caused by unstable clamping during flat steel cutting, ensuring that the cutting path is consistent with the programming settings, while avoiding flat steel deformation or surface indentation caused by uneven clamping force, thus significantly improving cutting accuracy and finished product quality.

[0012] Optionally, a movable seat is slidably connected to the connecting frame, a clamping cylinder is fixedly connected to the movable seat, a movable block is fixedly connected to the output shaft of the clamping cylinder, the movable block is used to clamp the end of the cut flat steel, and a receiving block is slidably connected to the movable seat, the receiving block is used to support the bottom position of the end of the cut flat steel.

[0013] This application effectively solves the problem of slanted cut surfaces caused by lack of support at the free end after flat steel is cut. By using a clamping cylinder and a receiving block to clamp the steel together, the cut surface is kept perpendicular, improving the dimensional accuracy and cut smoothness of the parts and meeting the requirements of high-precision processing.

[0014] Optionally, a fixed rack is fixedly connected to the connecting frame, a moving motor is fixedly connected to the moving base, and a moving gear is fixedly connected to the output shaft of the moving motor. The moving gear can mesh with the fixed rack and drive the moving base to move.

[0015] Optionally, a positioning block is slidably connected to the placement frame, and the positioning block is axially distributed at the discharge port on the placement frame. An abutting wheel is rotatably connected to the abutting block, and the abutting wheel is used to abut against the side wall of the uncut flat steel.

[0016] Optionally, a feeding rack is fixedly connected to the end of the placement rack away from the connecting rack, and a U-shaped block is fixedly connected to the feeding rack, the U-shaped block being able to lift the flat steel.

[0017] Optionally, a plurality of abutment balls are fixedly connected to the inner sidewall of the U-shaped block. The abutment balls are used to reduce the friction between the flat steel inside the U-shaped block and the sidewall of the U-shaped block when the flat steel moves.

[0018] It achieves continuous and stable support for flat steel during the conveying process, preventing the cutting surface from tilting and dimensional deviations caused by the flat steel sagging under its own weight. At the same time, it reduces frictional wear between the flat steel surface and the conveying device, ensuring the stability of high-precision cutting operations.

[0019] Optionally, the moving mechanism further includes a first drag chain capable of driving the cutting head to move horizontally. The first drag chain is fixedly connected to the placement frame, and a sliding block is fixedly connected to one end of the first drag chain. A second drag chain is fixedly connected to the sliding block, and the cutting head and the sliding block are slidably connected. The second drag chain can drive the cutting head to slide vertically.

[0020] Secondly, a method for using a cutting device for processing stainless steel flat bars, the method of use being as follows: S1, the flat steel to be cut is straightened and conveyed to the U-shaped block on the loading rack, and moves to the center position of the abutment block through the U-shaped block. The positioning block moves toward the position close to the flat steel, so that the abutment roller clamps the flat steel, and the first drag chain and the second drag chain move to drive the cutting head to the cutting position of the flat steel. S2, the part of the flat steel that needs to be cut is moved to the clamping seat, and the flat steel is aligned in a straight line under the push of the support block. The moving motor is started, which drives the moving seat to the end position of the flat steel. The clamping cylinder is started, and the moving block and receiving block on the clamping cylinder clamp the flat steel. S3 causes the cutting head to perform laser cutting on the flat steel, and after cutting, the moving motor is started to move the cut flat steel away from the cutting position.

[0021] Optionally, in step S3, after a flat steel bar is cut, the moving motor drives the flat steel bar to move to a certain extent, and moves the next section of flat steel bar to be cut to a position above the flat steel bar. The clamping cylinder clamps the section of flat steel bar a second time, and after clamping, the previous section of flat steel bar supports the section of flat steel bar. This operation is repeated, and after a certain number of cuts, the cut flat steel bars are collected.

[0022] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. This application effectively suppresses three-dimensional deformation during flat steel cutting, ensuring the geometric accuracy of the cutting path. The material maintains a stable spatial position during processing, and the perpendicularity of the cut surface is significantly improved, meeting the requirements of high-precision processing. The combined design of bottom support and top clamping successfully balances the torque generated by the material's own weight, preventing material warping during cutting.

[0023] 2. This application effectively solves the problem of slanted cut surfaces caused by lack of support at the free end after flat steel is cut. By using the clamping cylinder and the receiving block to clamp the steel together, the cut surface is kept perpendicular, improving the dimensional accuracy of the parts and the flatness of the cut surface, thus meeting the requirements of high-precision processing.

[0024] 3. It achieves continuous and stable support for flat steel during the conveying process, preventing the cutting surface from tilting and dimensional deviations caused by the flat steel sagging under its own weight. At the same time, it reduces frictional wear between the flat steel surface and the conveying device, ensuring the stability of high-precision cutting operations. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 1-7 The technical solutions of the embodiments of this application are clearly and completely described herein. All other embodiments obtained by those skilled in the art based on the described embodiments are within the scope of protection of this application.

[0028] Firstly, a cutting device for processing stainless steel flat bars adopts the following technical solution, including: like Figure 1 As shown, this embodiment provides a cutting device for processing stainless steel flat bars, including a placement frame 1, a moving mechanism 2, a positioning and clamping mechanism, a moving and dragging mechanism, a centering mechanism, and a receiving mechanism. The placement frame 1 is set on a horizontal plane and is used to receive the straightened long strip flat bars. The receiving mechanism is set at one end close to the existing straightening equipment and is used to receive the straightened flat bars and transport them to the placement frame 1. The centering mechanism is set at the center of the placement frame 1 and is used to position the flat bars at the center of the placement frame 1. The moving mechanism 2 is set on the placement frame 1 and is capable of cutting the flat bars. The positioning and clamping mechanism is set on the side of the placement frame 1 away from the receiving mechanism and is used to support the cut part of the flat bars to reduce over-cutting caused by the upward curvature of the cut part of the flat bars. The moving and dragging mechanism is used to move the cut flat bars.

[0029] like Figure 1 and Figure 2 As shown, the moving mechanism 2 includes a first drag chain 22, a sliding block 23, a second drag chain 24, and a cutting head 21. The first drag chain 22 is fixedly connected to the placement frame 1, the sliding block 23 is slidably connected to the placement frame 1, and the sliding block 23 and the first drag chain 22 are fixedly connected. The sliding drag chain can slide horizontally under the drive of the first drag chain 22. The second drag chain 24 is fixedly connected to the drag block, and the cutting head 21 is slidably connected to the sliding block 23. The second drag chain 24 can drive the cutting head 21 to slide vertically, and the cutting head 21 is set as a laser cutting head 21.

[0030] When it is necessary to cut the flat steel, the first drag chain 22 drives the sliding block 23 to move horizontally, and the cutting head 21 moves to the initial cutting position of the flat steel. The second drag chain 24 drives the cutting head 21 to move towards the cutting position of the flat steel, so that the blade of the cutting head 21 is aligned with the cutting point of the flat steel. The cutting head 21 is started to cut the flat steel. During the cutting process, the first drag chain 22 drives the sliding block 23 to move, and then drives the cutting head 21 to move towards the cutting point of the flat steel.

[0031] like Figure 2 and Figure 3 As shown, the positioning and clamping mechanism includes a connecting frame 3, a clamping seat 31, a clamping block 32, a support block 33, an abutment block 34, and a push spring 35. The connecting frame 3 is fixedly connected to the side of the placement frame 1 near the cutting head 21. The clamping seat 31 is fixedly connected to the connecting frame 3. Two clamping blocks 32 are provided, and both clamping blocks 32 are slidably connected to the clamping seat 31. The clamping blocks 32 are used to clamp both sides of the flat steel. In actual use, a mechanism can be added to the clamping blocks 32 to move them toward a position closer to the flat steel. The support block 33 is slidably connected to the clamping seat 31 and is used to support the bottom of the flat steel. The abutment block 34 is slidably connected to the clamping seat 31 and is used to press the top of the flat steel. The push spring 35 is fixedly connected to the support block 33 and the abutment block 34 and is used to move the support block 33 and the abutment block 34 toward the bottom or top of the flat steel.

[0032] Before cutting the flat steel, the part to be cut is moved out from the cutting head 21, and the cutting part of the flat steel is moved to the center position of the two opposing clamping blocks 32. The clamping blocks 32 move towards the sides close to the flat steel under the action of the spring. The support block 33 and the abutment block 34 abut against the bottom and top of the flat steel respectively under the push of the push spring 35. When cutting some long flat steel, the flat steel can be clamped and supported, reducing the upward tilting of the flat steel at the cutting position.

[0033] like Figure 2 and Figure 3 As shown, the moving and dragging mechanism includes a moving seat 4, a clamping cylinder 41, a moving block 42, and a receiving block 43. The moving seat 4 is slidably connected to the connecting frame 3. The clamping cylinder 41 is fixedly connected to the moving seat 4. The moving block 42 is fixedly connected to the output shaft of the clamping cylinder 41 and can move towards the top position of the flat steel under the push of the clamping cylinder 41. The receiving block 43 is slidably connected to the moving seat 4 and is used to support the bottom position of the cut flat steel.

[0034] Among them, such as Figure 2As shown, a fixed rack 44 is fixedly connected to the connecting frame 3, a moving motor 45 is fixedly connected to the moving seat 4, and a moving gear 46 is fixedly connected to the output shaft of the moving motor 45. The moving gear 46 can mesh with the fixed rack 44 and drive the moving seat 4 to move.

[0035] Before cutting the flat steel, the moving motor 45 is started, causing the output shaft of the moving motor 45 to rotate, which in turn drives the moving gear 46 to rotate. The moving gear 46 meshes with the fixed rack 44. During the rotation of the moving gear 46, the moving seat 4 moves towards the end position close to the flat steel. During the movement, the clamping cylinder 41 is activated, causing the output shaft of the clamping cylinder 41 to move upward, so that the flat steel can be clamped at the middle position of the moving block 42 and the receiving block 43. After the flat steel is cut, the moving seat 4 moves to a certain extent away from the cutting head 21 by the driving of the moving motor 45.

[0036] like Figure 5 As shown, the centering mechanism includes a positioning block 5 and an abutting wheel 51. The positioning block 5 is slidably connected to the placement frame 1 and is axially distributed at the discharge port of the placement frame 1. The abutting wheel 51 is rotatably connected to the positioning block 5 and is used to abut against the side wall of the uncut flat steel.

[0037] As the flat steel moves toward the cutting head 21, it is kept in a fixed position by the positioning block 5 and the abutting roller 51, reducing the movement of the flat steel during cutting.

[0038] like Figure 1 and Figure 6 As shown, the receiving mechanism includes a feeding rack 6, a U-shaped block 61, and an abutment ball 62. The feeding rack 6 is fixedly connected to the placement rack 1 and is located at the end of the placement rack 1 away from the connecting rack 3. The U-shaped block 61 is fixedly connected to the feeding rack 6 and is used to support the flat steel. The abutment ball 62 is fixedly connected to the inner wall of the U-shaped block 61 and is used to reduce the friction between the flat steel inside the U-shaped block 61 and the U-shaped block 61 when it moves.

[0039] In use, the straightened flat steel is moved onto the U-shaped block 61 and then moved to the center position of the abutting roller 51 via the U-shaped block 61. After adjustment by the positioning block 5, the flat steel is positioned in the center. Before cutting the flat steel, the part to be cut is moved out from the cutting head 21, and the cutting part of the flat steel is moved to the center position of the two opposing clamping blocks 32. The clamping blocks 32 move towards the sides close to the flat steel under the action of the spring. The support block 33 and the abutting block 34 abut against the bottom and top of the flat steel respectively under the push of the push spring 35. When cutting some longer flat steel, the flat steel can be clamped and supported, reducing the upward tilting of the flat steel at the cutting position.

[0040] Before cutting the flat steel, the moving motor 45 is started, causing the output shaft of the moving motor 45 to rotate, which in turn drives the moving gear 46 to rotate. The moving gear 46 meshes with the fixed rack 44. During the rotation of the moving gear 46, the moving seat 4 moves towards the end position close to the flat steel. During the movement, the clamping cylinder 41 is activated, causing the output shaft of the clamping cylinder 41 to move upward, so that the flat steel can be clamped at the middle position between the moving block 42 and the receiving block 43.

[0041] When it is necessary to cut the flat steel, the first drag chain 22 drives the sliding block 23 to move horizontally, and the cutting head 21 moves to the initial cutting position of the flat steel. The second drag chain 24 drives the cutting head 21 to move towards the cutting position of the flat steel, so that the blade of the cutting head 21 is aligned with the cutting point of the flat steel. The cutting head 21 is started to cut the flat steel. During the cutting process, the first drag chain 22 drives the sliding block 23 to move, and then drives the cutting head 21 to move towards the cutting point of the flat steel.

[0042] After the flat steel is cut, the moving seat 4 is moved away from the cutting head 21 by the moving motor 45. After the movement, the flat steel is moved out of the cutting position of the cutting head 21. After it is moved out, the weight of the flat steel presses the support block 33 and the receiving block 43 downward to place the flat steel. The next section of flat steel is moved to the center position of the support block 33 and the abutment block 34, and the clamping cylinder 41 drives the moving block 42 to move upward to clamp the next section of flat steel. After clamping, it is moved to a certain extent so that the flat steel is stacked on top of the previous section of flat steel. This operation is repeated (e.g., ...). Figure 7 (As shown, the flat steel is stacked), and after a certain stacking degree, the workers collect the flat steel.

[0043] In this embodiment, by precisely positioning the flat steel in the center of the clamping block 32 before cutting and elastically pressing it with the upper and lower support blocks 33 and the abutment block 34, vibration and displacement during the cutting process are effectively eliminated, ensuring the perpendicularity and smoothness of the cut surface. This fundamentally solves the problem of dimensional deviation caused by the upward warping of the workpiece and significantly improves the first-pass yield of the finished product.

[0044] In this embodiment, by constructing a locally rigid support system near the cutting point, the cutting part of the flexible strip is successfully stabilized and fixed, fundamentally overcoming the probability of the long material curling up, thereby improving the processing accuracy of long flat steel and enabling high-efficiency cutting.

[0045] In this embodiment, by automatically removing the cut flat steel from the cutting area and placing it on an independent support, an ideal zero-stress observation environment is created, allowing all deformations of the workpiece caused by laser thermal stress to be realistically and intuitively exposed. This not only provides operators or online inspection systems with a window to instantly assess cutting quality and detect process anomalies, but also transforms quality control from final sampling inspection to continuous monitoring of each finished product, forming a closed loop of production-inspection-feedback.

[0046] In this embodiment, when clamping and moving the cut flat steel, the rigid constraint of the clamping cylinder 41 effectively prevents secondary twisting of the workpiece due to stress release during the transfer process. Its core advantage lies in the precise stacking operation, cleverly utilizing the weight of the upper flat steel to apply continuous and uniform pressure to the lower workpiece, which may be warped or bent. This "gravity straightening" mechanism continuously physically corrects the workpiece during the stacking and resting period, effectively integrating the traditional cold-pressing straightening process seamlessly into the automated production process.

[0047] In this embodiment, the flatness of a single section of flat steel is significantly improved, and the entire batch of finished products undergoes a unified shaping process, which greatly reduces the cost and difficulty of subsequent manual straightening and directly improves the geometric accuracy and delivery quality of the final product.

[0048] In this embodiment, continuous and stable support is achieved for the flat steel during the conveying process, preventing the cutting surface from tilting and dimensional deviations caused by the flat steel sagging under its own weight. At the same time, frictional wear between the flat steel surface and the conveying device is reduced, ensuring the stability of high-precision cutting operations.

[0049] Secondly, a method for using a cutting device for processing stainless steel flat bars, the method of use being as follows: S1, the flat steel to be cut is straightened and conveyed to the U-shaped block 61 on the feeding rack 6, and moves to the center position of the abutment block 34 via the U-shaped block 61. The positioning block 5 moves toward the position close to the flat steel, so that the abutment wheel 51 clamps the flat steel, and the first drag chain 22 and the second drag chain 24 move to drive the cutting head 21 to the cutting position of the flat steel. S2, the part of the flat steel that needs to be cut is moved to the clamping seat 31, and the flat steel is aligned with the support block 33 under the push of the support block 33. The moving motor 45 is started, which drives the moving seat 4 to move to the end position of the flat steel. The clamping cylinder 41 is started, which causes the moving block 42 and the receiving block 43 on the clamping cylinder 41 to clamp the flat steel. S3, the cutting head 21 performs laser cutting on the flat steel, and after cutting, the moving motor 45 is started, so that the moving motor 45 drives the cut flat steel to move away from the cutting position.

[0050] In step S3, after a flat steel bar is cut, the moving motor 45 drives the flat steel bar to move to a certain extent, and moves the next section of flat steel bar to be cut to a position above the flat steel bar. The clamping cylinder 41 clamps the section of flat steel bar a second time, and after clamping, the previous section of flat steel bar supports the section of flat steel bar. This operation is repeated, and after a certain number of cuts are completed, the cut flat steel bars are collected.

[0051] The implementation principle of a cutting device for processing stainless steel flat bars in this application embodiment is as follows: First, the straightened flat steel is moved onto the U-shaped block 61, which then moves the flat steel until it abuts the center of the rotating wheel 51. Here, the positioning block 5 adjusts the flat steel to ensure it is precisely centered. Before the cutting operation begins, the section to be cut is moved to the cutting head 21, and simultaneously, the cutting section of the flat steel is moved to the center of two opposing clamping blocks 32. Then, under the action of springs, the clamping blocks 32 move towards the sides of the flat steel to clamp it. At the same time, the support block 33 and the abutment block 34, pushed by their respective push springs 35, abut against the bottom and top ends of the flat steel, respectively. This clamping and support mechanism effectively reduces the upward warping caused by stress at the cutting point when cutting longer flat steel.

[0052] Before the actual cutting, the moving motor 45 is started, and the rotation of its output shaft drives the moving gear 46 to rotate. The moving gear 46 meshes with the fixed rack 44, thereby driving the moving seat 4 to move towards a position closer to the end of the flat steel during rotation. At the same time as the moving seat 4 moves, the clamping cylinder 41 is activated, and its output shaft moves upward, so that the flat steel can be clamped at the middle position between the moving block 42 and the receiving block 43.

[0053] When the cutting command is executed, the first cable chain 22 drives the sliding block 23 to move horizontally, moving the cutting head 21 to the initial position of the flat steel cutting location. Then, the second cable chain 24 drives the cutting head 21 further towards the cutting position closer to the flat steel, ensuring that the cutting tip of the cutting head 21 is precisely aligned with the cutting point of the flat steel. Subsequently, the cutting head 21 is activated to cut the flat steel. During the cutting process, the first cable chain 22 continuously drives the sliding block 23 to move, thereby driving the cutting head 21 along the cutting path of the flat steel from the initial position to the cut point.

[0054] After cutting is completed, the moving motor 45 starts again, driving the moving seat 4 to move a certain distance away from the cutting head 21. This movement removes the cut flat steel segment from the cutting position of the cutting head 21. After removal, the flat steel segment, under its own weight, presses down the support block 33 and the receiving block 43, thus achieving placement. At this time, the next flat steel segment to be cut is moved to the center position of the support block 33 and the receiving block 34. The clamping cylinder 41 then drives the moving block 42 to move upward, clamping the new flat steel segment. After clamping, the moving seat 4 moves again, stacking the new flat steel segment on top of the previous flat steel segment. This cycle of cutting, removal, placement, clamping, and stacking is repeated (e.g., ...). Figure 7 (As shown, the flat steel is stacked). Once the stack reaches a certain size, workers collect the pile of flat steel.

[0055] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.

The cutting equipment for processing stainless steel flat bars according to claim 1, characterized in that: Multiple abutment balls are fixedly connected to the inner sidewall of the U-shaped block. The abutment balls are used to reduce the friction between the flat steel inside the U-shaped block and the sidewall of the U-shaped block when the flat steel moves.

3. The cutting equipment for processing stainless steel flat bars according to claim 2, characterized in that: The moving mechanism also includes a first drag chain that can drive the cutting head to move horizontally. The first drag chain is fixedly connected to the placement frame. A sliding block is fixedly connected to one end of the first drag chain. A second drag chain is fixedly connected to the sliding block. The cutting head and the sliding block are slidably connected. The second drag chain can drive the cutting head to slide vertically.

4. A method of using a cutting device for processing stainless steel flat bars, applicable to the cutting device for processing stainless steel flat bars as described in claim 3: S1, the flat steel to be cut is straightened and conveyed to the U-shaped block on the loading rack, and moves to the center position of the positioning block through the U-shaped block. The positioning block moves towards the position close to the flat steel, so that the abutment roller clamps the flat steel, and the first drag chain and the second drag chain move to drive the cutting head to the cutting position of the flat steel. S2, the part of the flat steel that needs to be cut is moved to the clamping seat, and the flat steel is aligned in a straight line under the push of the support block. The moving motor is started, which drives the moving seat to the end position of the flat steel. The clamping cylinder is started, and the moving block and receiving block on the clamping cylinder clamp the flat steel. S3 causes the cutting head to perform laser cutting on the flat steel, and after cutting, the moving motor is started to move the cut flat steel away from the cutting position.

5. The method of using the cutting equipment for processing stainless steel flat bars according to claim 4, characterized in that: In step S3, after a flat steel bar is cut, the moving motor drives the flat steel bar to move a certain distance, and moves the next section of flat steel bar to be cut to a position above the flat steel bar. The clamping cylinder clamps the next section of flat steel bar to be cut a second time, and after clamping, the previous section of flat steel bar supports the next section of flat steel bar. This operation is repeated, and after a certain number of cuts are completed, the cut flat steel bars are collected.
