Description

Technical Field

[0001] This invention relates to the field of circular saw cutting technology, specifically to a circular saw cutting device and method for forming metal sheets.

[0002] In the metal sheet forming and processing process, circular saw cutting equipment is the core equipment for achieving fixed-length and fixed-shape cutting of sheet metal, and it is widely used in many fields such as machinery manufacturing, building materials, and automotive parts processing.

[0003] Currently, existing circular saw cutting equipment for metal sheets still has some problems in practical applications, as follows: First, the clamping and fixing mechanisms of existing cutting equipment are mostly fixed structures. When the sheet is too thick, the clamping pressure is insufficient, and the sheet is prone to displacement and shaking during the cutting process, resulting in cutting deviation. When the sheet is too thin, the clamping pressure is too high, which can easily cause the surface of the sheet to be squeezed and deformed, affecting the forming quality. At the same time, the high-speed rotation of the circular saw and the friction between it and the sheet during the cutting process will generate outward thrust, reducing the cutting accuracy.

[0004] Secondly, the cutting process generates a large amount of metal shavings, which easily remain in the cutting kerf. This not only increases the frictional resistance between the circular saw and the sheet metal, accelerating the wear of the circular saw, but may also cause burrs and scratches on the cut surface, affecting the cutting quality. At the same time, high-speed friction generates a lot of heat. If it cannot be cooled in time, the circular saw will become too hot, reducing its hardness and service life. Furthermore, high temperatures may cause local deformation of the metal sheet, affecting subsequent forming and processing. Existing equipment's jet cooling and shavings blowing structures are mostly fixed in angle and airflow, making it impossible to adjust the jet angle and shavings blowing amplitude according to the sheet metal thickness. For thicker sheets, fixed-amplitude shavings blowing is insufficient to clean the shavings in the kerf, and fixed-angle jet cooling is ineffective.

[0005] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0019] Preferably, the outer wall of the adjusting ring is always in sliding engagement with the outer walls of any two adjacent inclined abutment blocks.

[0020] A method for using a circular saw cutting device for forming metal sheets, the method comprising the following steps:

[0021] S1: Place the main body of the board to be cut on the base, and use the clamping devices symmetrically arranged on both sides of the base to position and fix the side wall of the main body of the board;

[0022] S2: Start the electric actuator in the lifting mechanism. The electric actuator drives the receiving plate, sliding column, connecting ring tube, receiving rod and inclined column to move vertically. The lower end of the inclined column is attached to the main body of the plate to complete the initial limit. The thicker the main body of the plate, the closer the inclined column moves down. The thinner the main body of the plate, the farther the inclined column moves down.

[0023] S3: Start the servo motor in the rotating mechanism. The servo motor drives the support ring column, connecting ring tube and inclined column to rotate synchronously through the first gear and the second gear. The inclined surface block on the side wall of the inclined column rotates in a ring with it.

[0024] S4: The sliding head of the inclined plane block pushing reciprocating mechanism and the adjusting ring of the pushing mechanism increase the clamping force of the pressure plate when the main body of the plate is thick, resisting the outward pushing force generated by cutting; when the main body of the plate is thin, the clamping pressure decreases to avoid the plate being squeezed and deformed. The first roller and the second roller reduce the friction of the pressure plate movement; the inclined plane block synchronously pushes the pushing column of the swing mechanism, and the torsion spring resets to drive the jet head to swing back and forth; when the main body of the plate is thick, the jet head swings slightly to accurately clean the chips and cool down; when the main body of the plate is thin, the jet head swings significantly to blow the chips and cool down comprehensively.

[0025] S5: Start the cutting main body to cut the main body of the board. All mechanisms work together continuously until the board cutting is completed.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention achieves adjustable clamping force for metal sheets of different thicknesses through the coordinated operation of a lifting mechanism, a reciprocating mechanism, and a pushing mechanism. The electric actuator in the lifting mechanism drives the sliding column, connecting ring tube, and inclined column to reciprocate up and down. The buffer pad at the lower end of the inclined column can conform to the main body of the sheet material of different thicknesses, achieving initial positioning. Simultaneously, the thicker the sheet material, the shorter the downward movement distance of the inclined column; the thinner the sheet material, the farther the downward movement distance. During the rotation of the inclined column, the inclined surface blocks distributed in a ring on its sidewall form a pushing engagement with the sliding head of the reciprocating mechanism and the adjusting ring of the pushing mechanism. When the sheet material... When the material is thicker, the lower end of the inclined abutment block pushes against the sliding head and adjusting ring, causing the sliding frame and pressure plate to move further towards the cutting center. This results in greater pressure from the extrusion block on the pressure plate, providing stronger clamping and fixing force for thicker materials and reducing the outward pushing force during cutting, which affects the material's wobbling. When the material is thinner, the upper end of the inclined abutment block pushes against the sliding head and adjusting ring, reducing the clamping pressure and the distance to the edge, preventing the thin material from being squeezed and deformed. In addition, the first roller at the lower end of the pressure plate and the second roller on the extrusion block effectively reduce the friction during the reciprocating motion of the pressure plate, improving processing efficiency and quality.

[0028] 2. This invention utilizes the synergistic effect of a rotating mechanism and a swinging mechanism. The servo motor in the rotating mechanism drives the first and second gears to rotate, which in turn drives the supporting ring column, connecting ring tube, and inclined column to rotate synchronously. The rotation of the inclined column drives the pushing column of the swinging mechanism to move. Combined with the resetting effect of the torsion spring between the support frame and the receiving shaft, the swinging motion of the air jet head is achieved. When the plate is thick, the downward movement distance of the inclined column is short, and the narrower upper end of the inclined abutment block pushes against the pushing column, resulting in a smaller swinging reciprocating distance of the air jet head. Due to the longer cutting time, more waste, and higher temperature of thicker plates, small-amplitude swinging air blowing can blow out the waste in the cutting gap, preventing waste blockage, and simultaneously cooling the cutting groove, improving cooling efficiency, reducing circular saw wear, and reducing local deformation of the plate. When the plate is thin, the wider lower end of the inclined abutment block pushes against the pushing column, and the swinging reciprocating distance of the air jet head is larger, which can blow away the waste generated during cutting, reduce the cutting temperature, and prevent the thin plate from deforming due to local high temperature.

[0038] Please see Figures 1-7 This invention provides a technical solution: a circular saw cutting device for forming metal sheets, including a base 103, a mounting frame 101 fixedly mounted on the base 103, a cutting body 104 fixedly mounted on the inner wall of the mounting frame 101, clamping devices for fixing the side walls of the sheet body 102 symmetrically arranged on the side walls of the base 103, an air jet head 107 for blowing air and cooling cutting waste on the mounting side wall of the cutting body 104 located inside the mounting frame 101, a pressure plate 108 for providing pressure to the sheet body 102 towards the cutting center on the mounting side wall of the cutting body 104, a mounting seat 105 provided on the mounting frame 101, and a support seat 106 fixedly mounted on the inner wall of the mounting frame 101;

[0039] A lifting mechanism is provided in the mounting base 105 and is used to adjust the pressure provided by the pressure plate 108 to the plate body 102 when the thickness of the plate body 102 is different.

[0040] A rotating mechanism is provided on the support base 106 and is used to adjust the angle of the jet nozzle 107 when the thickness of the plate body 102 is different.

[0041] A swing mechanism is symmetrically arranged on one side of the cutting body 104 to blow away residual waste in the cutting gap and to cool down the generated frictional high temperature.

[0042] A reciprocating mechanism is symmetrically arranged on the other side of the cutting body 104 to provide pressure towards the cutting center during the cutting process, thereby improving the stability of the plate body 102 being clamped and fixed.

[0043] In one embodiment of the present invention, the lifting mechanism includes an electric actuator 201 fixedly installed in the mounting base 105. The output end of the electric actuator 201 is connected to a receiving plate 203. One end of a sliding column 202 is symmetrically fixedly installed at the lower end of the receiving plate 203. The sliding columns 202 are all slidably disposed in the support base 106. The upper end of the connecting ring tube 205 is rotatably engaged with the lower end of the sliding column 202. The lower end of the connecting ring tube 205 passes through the inner wall of the support ring column 206 and is connected to one end of a receiving rod 207. The other end of the receiving rod 207 is fixedly connected to an inclined column 204. The inner wall of the support ring column 206 is slidably engaged with the outer wall of the connecting ring tube 205.

[0044] When the electric actuator 201 is activated, it can drive the sliding column 202 and the receiving plate 203 to move up and down reciprocally. The sliding column 202 can drive the connecting ring tube 205 and the receiving rod 207 to move up and down reciprocally. The receiving rod 207 can drive the inclined column 204 to move up and down reciprocally.

[0045] In one embodiment of the present invention, the rotating mechanism includes a fixed base 301 fixedly installed on the bottom wall of the support base 106. A connecting plate 302 is fixedly installed on the inner wall of the fixed base 301. A servo motor 303 is fixedly installed on the side wall of the connecting plate 302. The output end of the servo motor 303 is connected to a first gear 304. The first gear 304 meshes with a second gear 305. The second gear 305 is installed on the side wall of the support ring column 206. The side wall of the support ring column 206 and the inner wall of the second gear 305 are rotatably engaged.

[0046] The servo motor 303 is started, which drives the first gear 304 to rotate. The rotation of the first gear 304 drives the second gear 305 to rotate. The second gear 305 drives the support ring column 206 to rotate on the fixed seat 301. Since the connecting ring tube 205 slides inside the support ring column 206 and the lower end of the connecting ring tube 205 is in rotational engagement with the sliding column 202, the support ring column 206 can drive the connecting ring tube 205 to rotate. The connecting ring tube 205 drives the receiving rod 207 and the inclined column 204 to rotate.

[0047] In one embodiment of the present invention, the swing mechanism includes a support frame 405 fixedly mounted on the bottom wall of the fixed base 301. A receiving shaft plate 406 is rotatably mounted between the inner walls of the support frame 405. A torsion spring is provided between the side wall of the receiving shaft plate 406 and the inner wall of the support frame 405. A swing shaft 407 is fixedly mounted on the bottom wall of the receiving shaft plate 406. A connecting pipe 403 is fixedly mounted on the lower end of the swing shaft 407. A connecting port 404 is provided on the side wall of the connecting pipe 403. An air jet connection pipe 401 is provided on the lower end of the connecting pipe 403. A plurality of air jet heads 107 are provided on the side wall of the air jet connection pipe 401 near the cutting body 104. The connecting port 404 is connected to the air supply end of the air pump. The connecting port 404 is connected to the air jet heads 107 through the connecting pipe 403 and the air jet connection pipe 401. A fixing plate 408 is fixedly mounted on the side wall of the swing shaft 407. A pushing column 402 is fixedly mounted on the side wall of the fixing plate 408.

[0048] In one embodiment of the present invention, the reciprocating mechanism includes a limiting plate 501 fixedly installed on the bottom wall of the fixed base 301. A sliding groove is provided on the inner wall of the limiting plate 501. A sliding frame 502 is slidably installed in the sliding groove. A connecting column 505 is rotatably installed at the lower end of the sliding frame 502. A pressure plate 108 is detachably installed at the lower end of the connecting column 505. A first roller 503 is rotatably provided at the lower end of the pressure plate 108. A spring is provided between the side wall of the sliding frame 502 and the wall of the sliding groove. A sliding head 504 is slidably provided in the side wall of the sliding frame 502 near the inclined column 204. A spring is provided between the side wall of the sliding head 504 and the inner wall of the sliding frame 502. The pressure plate 108 cooperates with the pushing mechanism.

[0049] In one embodiment of the present invention, the first roller 503 is arranged in a direction parallel to the cutting line.

[0050] In one embodiment of the present invention, a plurality of inclined abutment blocks 109 with downward angles are distributed in a ring on the side wall of the inclined column 204, and the inclined abutment blocks 109 are in abutment cooperation with the push column 402 and the sliding head 504.

[0051] In one embodiment of the present invention, the pushing mechanism includes a sliding rod 602 slidably installed in the mounting groove on the bottom wall of the fixed seat 301. An adjusting ring 601 is fixedly installed at the lower end of the sliding rod 602. A pressing block 603 is fixedly installed on the bottom wall of the adjusting ring 601. The bottom wall of the pressing block 603 slides and presses against the top wall of the pressure plate 108. The cross-section of the adjusting ring 601 is semi-circular. The inner wall of the adjusting ring 601 slides and engages with the outer wall of the inclined abutment block 109. A spring is provided between the mounting groove wall and the side wall of the sliding rod 602. A plurality of second rollers 604 are rotatably provided on the side wall of the pressing block 603 near the pressure plate 108.

[0052] During the rotation of the inclined column 204, the inclined surface block 109 on the inclined column 204 also rotates synchronously. First, the electric actuator 201 is activated to drive the inclined column 204 up and down. Because the lower end of the inclined column 204 is equipped with a buffer pad, it can move downwards to clamp and limit the thickness of the sheet metal body 102. The greater the thickness of the sheet metal body 102, the shorter the downward distance of the inclined column 204; similarly, the thinner the sheet metal body 102, the farther the downward distance of the inclined column 204. The inclined column 204 can rotate... The pusher continuously moves against the pusher 402, pushing it closer to the cutting body 104. This allows the swing shaft 407, connecting pipe 403, jet connection pipe 401, and jet head 107 to rotate and swing synchronously on the support frame 405, moving closer to the cutting body 104. It is known that the jet head 107 is inclined and faces the cutting groove of the cutting body 104. The thicker the plate body 102, the shorter the downward movement of the inclined column 204. The position of the pusher 402 remains unchanged, and the lower end of the inclined block 109 facilitates the movement of the pusher 402. 2. The inclined abutment block 109 is arranged at an angle, narrower at the top and wider at the bottom. This allows the narrower end of the inclined abutment block 109 to push against the pusher post 402. This results in a shorter pushing distance compared to the thinner sheet metal body 102. The torsion spring resets the blowing angle of the jet head 107, achieving a shorter oscillating and reciprocating cooling motion of the jet head 107 against the cutting groove when the sheet metal body 102 is thicker. Because the sheet metal body 102 is thicker, the cooling effect during cutting is greater than that of the thinner sheet metal body 102. 02 The cutting dwell time is relatively long, and a lot of waste chips are generated during cutting. The friction temperature is high. The small-amplitude oscillating air blowing can blow out the waste chips blocked in the cutting groove and cool the cutting groove to a small extent, which improves the waste chip handling and cooling effect during the cutting of thicker plate body 102. Similarly, when the plate body 102 is thin, the air jet head 107 can perform a large-distance oscillating and reciprocating blowing motion on the cutting groove to cool it down. This can fully blow off the waste chips generated during cutting and cool the cutting groove.

[0053] During the downward movement of the inclined column 204, because the inclined column 204 is wider at the lower end, it can push against the adjusting ring 601 and the sliding rod 602 to move horizontally. When the main body of the sheet 102 is thicker, the inclined column 204 moves downward a shorter distance. The positions of the adjusting ring 601 and the pressing block 603 remain unchanged, allowing the adjusting ring 601 and the pressing block 603 to move horizontally further. The pressing block 603 can provide greater pressure to the pressure plate 108. Conversely, when the main body of the sheet 102 is thinner, the pressing block 603 can provide less pressure to the pressure plate 108. In addition, the inclined surface abutment block 109 can continuously push against the sliding head 504 to move horizontally during rotation, and cooperates with the spring to achieve reciprocating horizontal movement. When the main body of the sheet 102 is thicker, the inclined column 204 moves downward a shorter distance. With the position of the sliding head 504 unchanged, the sliding head 504 pushes against the lower end of the inclined block 109 in a horizontal movement, which can push the sliding head 504 a greater distance in horizontal displacement, causing the sliding frame 502, connecting column 505 and pressure plate 108 to move closer to the cutting body 104. Since the sliding head 504 is slidably set in the sliding frame 502, it can avoid interference from the inclined block 109 pushing against it, and provide a pressure towards the center for the cutting body 102, improving the stability of clamping and fixing the body 102, and avoiding the outward pushing force generated during cutting from affecting the stability of clamping the body 102 and thus affecting the cutting accuracy. In addition, the second roller 604 is used to reduce the friction between the pressure plate 108 and the extrusion block 603 during the reciprocating horizontal movement.

[0054] In one embodiment of the present invention, the outer wall of the adjusting ring 601 is always in sliding engagement with the outer walls of any two adjacent inclined abutment blocks 109.

[0055] During the rotation of the inclined plane block 109, the adjusting ring 601 and the inclined plane block 109 can always maintain a sliding fit.

[0056] A method for cutting metal sheets using a circular saw, the method comprising the following steps:

[0057] S1: Place the main body 102 of the board to be cut on the base 103, and fix the side wall of the main body 102 of the board by the clamping devices symmetrically arranged on both sides of the base 103.

[0058] S2: Start the electric push rod 201 in the lifting mechanism. The electric push rod 201 drives the receiving plate 203, sliding column 202, connecting ring tube 205, receiving rod 207 and inclined column 204 to move vertically. The lower end of the inclined column 204 is attached to the main body of the plate 102 to complete the initial limit. The thicker the main body of the plate 102, the closer the inclined column 204 moves down. The thinner the main body of the plate 102, the farther the inclined column 204 moves down.

[0059] S3: Start the servo motor 303 in the rotating mechanism. The servo motor 303 drives the support ring column 206, the connecting ring tube 205 and the inclined column 204 to rotate synchronously through the first gear 304 and the second gear 305. The inclined surface block 109 on the side wall of the inclined column 204 rotates in a ring with it.

[0060] S4: The inclined block 109 pushes the sliding head 504 of the reciprocating mechanism and the adjusting ring 601 of the pushing mechanism. When the plate body 102 is thick, the clamping force of the pressure plate 108 increases to resist the outward pushing force generated by cutting. When the plate body 102 is thin, the clamping pressure decreases to avoid the plate being squeezed and deformed. The first roller 503 and the second roller 604 reduce the friction of the pressure plate 108.

[0061] The inclined block 109 synchronously pushes the push column 402 of the swing mechanism, and the torsion spring resets to drive the jet head 107 to swing back and forth; when the main body of the plate 102 is thick, the jet head 107 swings slightly to accurately remove chips and cool down; when the main body of the plate 102 is thin, the jet head 107 swings significantly to blow chips and cool down.

[0062] S5: Start the cutting body 104 to cut the plate body 102. All mechanisms work together continuously until the plate cutting is completed.

[0063] Working principle: Starting the electric actuator 201 can drive the sliding column 202 and the receiving plate 203 to move up and down reciprocally. The sliding column 202 can drive the connecting ring tube 205 and the receiving rod 207 to move up and down reciprocally. The receiving rod 207 can drive the inclined column 204 to move up and down reciprocally.

[0064] The servo motor 303 is started, which drives the first gear 304 to rotate. The rotation of the first gear 304 drives the second gear 305 to rotate. The second gear 305 drives the support ring column 206 to rotate on the fixed seat 301. Since the connecting ring tube 205 slides inside the support ring column 206 and the lower end of the connecting ring tube 205 is in rotational engagement with the sliding column 202, the support ring column 206 can drive the connecting ring tube 205 to rotate. The connecting ring tube 205 drives the receiving rod 207 and the inclined column 204 to rotate.

[0065] During the rotation of the inclined column 204, the inclined surface block 109 on the inclined column 204 also rotates synchronously. First, the electric actuator 201 is activated to drive the inclined column 204 up and down. Because the lower end of the inclined column 204 is equipped with a buffer pad, it can move downwards to clamp and limit the thickness of the sheet metal body 102. The greater the thickness of the sheet metal body 102, the shorter the downward distance of the inclined column 204; similarly, the thinner the sheet metal body 102, the farther the downward distance of the inclined column 204. The inclined column 204 can rotate... The pusher continuously moves against the pusher 402, pushing it closer to the cutting body 104. This allows the swing shaft 407, connecting pipe 403, jet connection pipe 401, and jet head 107 to rotate and swing synchronously on the support frame 405, moving closer to the cutting body 104. It is known that the jet head 107 is inclined and faces the cutting groove of the cutting body 104. The thicker the plate body 102, the shorter the downward movement of the inclined column 204. The position of the pusher 402 remains unchanged, and the lower end of the inclined block 109 facilitates the movement of the pusher 402. 2. The inclined abutment block 109 is arranged at an angle, narrower at the top and wider at the bottom. This allows the narrower end of the inclined abutment block 109 to push against the pusher post 402. This results in a shorter pushing distance compared to the thinner sheet metal body 102. The torsion spring resets the blowing angle of the jet head 107, achieving a shorter oscillating and reciprocating cooling motion of the jet head 107 against the cutting groove when the sheet metal body 102 is thicker. Because the sheet metal body 102 is thicker, the cooling effect during cutting is greater than that of the thinner sheet metal body 102. 02 The cutting dwell time is relatively long, and a lot of waste chips are generated during the cutting process. The friction temperature is high. The small-amplitude oscillating air blowing can blow out the waste chips blocked in the cutting groove and cool the cutting groove to a small extent, which improves the waste chip handling and cooling effect during the cutting of thicker plate body 102. Similarly, when the plate body 102 is thin, the air jet head 107 can perform a large oscillating reciprocating motion on the cutting groove to blow away the waste chips generated during the cutting process and cool the cutting groove.

[0066] During the downward movement of the inclined column 204, because the inclined column 204 is wider at the lower end, it can push against the adjusting ring 601 and the sliding rod 602 to move horizontally. When the main body of the sheet 102 is thicker, the inclined column 204 moves downward a shorter distance. The positions of the adjusting ring 601 and the pressing block 603 remain unchanged, allowing the adjusting ring 601 and the pressing block 603 to move horizontally further. The pressing block 603 can provide greater pressure to the pressure plate 108. Conversely, when the main body of the sheet 102 is thinner, the pressing block 603 can provide less pressure to the pressure plate 108. In addition, the inclined surface abutment block 109 can continuously push against the sliding head 504 to move horizontally during rotation, and cooperates with the spring to achieve reciprocating horizontal movement. When the main body of the sheet 102 is thicker, the inclined column 204 moves downward a shorter distance. With the position of the sliding head 504 unchanged, the sliding head 504 pushes against the lower end of the inclined block 109 in a horizontal movement, which can push the sliding head 504 a greater distance in horizontal displacement, causing the sliding frame 502, connecting column 505 and pressure plate 108 to move closer to the cutting body 104. Since the sliding head 504 is slidably set in the sliding frame 502, it can avoid interference from the inclined block 109 pushing against it, and provide a pressure towards the center for the cutting body 102, improving the stability of clamping and fixing the body 102, and avoiding the outward pushing force generated during cutting from affecting the stability of clamping the body 102 and thus affecting the cutting accuracy. In addition, the second roller 604 is used to reduce the friction between the pressure plate 108 and the extrusion block 603 during the reciprocating horizontal movement.
