[0004] However, there are still the following problems: The side clearance of the cutting edge of traditional shearing machines is mostly fixed, making it difficult to adapt to steel strips with a wide thickness range and various materials, resulting in burrs on the shearing edge or increased tool wear. Most of the existing adjustable side clearance shearing machines rely on manual operation, with low efficiency and unable to meet the requirements of continuous production. Summary of the Invention

[0017] A shearing method based on edge clearance adjustment of the cutting edge uses the above automatic shearing machine and includes the following steps:

[0022] Compared with the prior art, the present invention provides an automatic shearing machine, which has the following beneficial effects:

[0023] 1. For this automatic shearing machine, the steel strip coil is placed beside the machine frame, and then the steel strip is conveyed from the steel strip coil into the through hole of the machine frame. When the steel strip passes through the machine frame to the required length for shearing the steel strip, the conveyance of the steel strip is stopped. The lower cutting knife assembly is used to press against the upper cutting knife assembly to shear the steel strip. The sheared steel strip will pass under the camera detector, and the camera detector detects the shearing edge of the steel strip. When there are burrs on the shearing edge of the steel strip, the upper cutting knife assembly is immediately controlled to move horizontally on the machine frame so that the upper cutting knife assembly adjusts the size of the side clearance and completes the adjustment before the steel strip extends to the required length again. This enables the shearing machine to handle the burr problem on the shearing edge of the steel strip without stopping the machine. When there are wavy edges on the shearing edge of the steel strip, the oil circuit cut-off assembly cuts off the power source conveyed to the lower cutting knife assembly, and then adjusts the position of the steel strip coil so that the unwinding position, shearing position, and winding position of the entire shearing machine are in a straight line, thereby eliminating the wavy edges generated on the shearing edge of the steel strip. Thus, when problems occur on the shearing edge of the steel strip, the equipment can be improved in a timely manner, automatically eliminating equipment problems, avoiding the large-scale production of unqualified products, replacing manual operation to adjust the equipment, and improving the production efficiency of the shearing machine.

[0024] 2. For this automatic shearing machine, through the settings of the first guiding cover and the second guiding cover, when the steel coil delivers the steel strip, there is no need for manual assistance to convey the steel strip into the shearing machine, improving the automation degree of the shearing machine, facilitating the operation of the shearing machine, and thereby improving the production efficiency of the shearing machine from the side.

[0025] 3. For this automatic shearing machine, through the setting of the moving table, the shearing machine can additionally automatically handle the problem of wavy edges on the shearing edge of the steel strip on the original basis, improving the applicability of the shearing machine.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes an automatic shearing machine and a shearing method based on the adjustment of the side clearance of the cutting edge.

[0037] Embodiment 1, in a typical implementation manner of the present application, as Figure 1As shown in the figure, an automatic shearing machine includes a frame 1, a shearing mechanism 2 provided on the frame 1, and an auxiliary mechanism 3 provided beside the frame 1. The shearing mechanism 2 includes an upper cutter assembly 2001 and a lower cutter assembly 2002. The upper cutter assembly 2001 is provided on the frame 1, and the lower cutter assembly 2002 is provided on the frame 1. The upper cutter assembly 2001 is directly above the lower cutter assembly 2002. The lower cutter assembly 2002 moves towards the upper cutter assembly 2001 to shear the steel strip.

[0038] The auxiliary mechanism 3 includes an oil circuit cutoff assembly 3001 and a camera detector 310. The camera detector 310 is provided beside the frame 1. The camera detector 310 detects the cut edge of the steel strip after shearing. The oil circuit cutoff assembly 3001 is provided on the frame 1. The oil circuit cutoff assembly 3001 controls the on-off of the power source for the movement of the lower cutter assembly 2002.

[0039] The camera detector 310 detects the steel strip. When there are burrs on the shearing edge of the steel strip, it controls the upper cutter assembly 2001 to move horizontally to adjust the side clearance. When there are wavy edges on the shearing edge of the steel strip, the oil circuit cutoff assembly 3001 disconnects the power source for the operation of the lower cutter assembly 2002 and adjusts the position of the steel strip coil.

[0040] When using the present invention:

[0041] Place the steel strip coil beside the frame 1, and then convey the steel strip from the steel strip coil through the through hole of the frame 1. When the steel strip passes through the frame 1 to the required length for shearing the steel strip, stop conveying the steel strip. Use the lower cutter assembly 2002 to abut against the upper cutter assembly 2001 to shear the steel strip. The sheared steel strip will pass under the camera detector 310. The camera detector 310 detects the shearing edge of the steel strip. When there are burrs on the shearing edge of the steel strip, immediately control the upper cutter assembly 2001 to move horizontally on the frame 1 so that the upper cutter assembly 2001 adjusts the size of the side clearance and completes the adjustment before the steel strip extends to the required length again, enabling the shearing machine to handle the problem of burrs on the shearing edge of the steel strip without stopping. When there are wavy edges on the shearing edge of the steel strip, the oil circuit cutoff assembly 3001 cuts off the power source conveyed to the lower cutter assembly 2002, and then adjusts the position of the steel strip coil so that the unwinding position, shearing position, and winding position of the entire shearing machine are in a straight line, thereby eliminating the wavy edges generated on the shearing edge of the steel strip. Thus, when problems occur on the shearing edge of the steel strip, the equipment can be improved in a timely manner, automatically eliminating equipment problems, avoiding the large-scale production of unqualified products, replacing manual operation to adjust the equipment, and improving the production efficiency of the shearing machine.

[0042] Embodiment 2, as Figures 2 - 4As shown in the figure, the difference from the above embodiment is that the shearing mechanism 2 further includes a first upper blade 21. There are two through holes opened on the frame 1, and the through holes on the frame 1 are symmetrically distributed up and down. The inner top end of the through hole above the frame 1 is slidably fitted with the first upper blade 21. A first planetary reducer 22 is fixedly installed on the frame 1. A threaded screw rod is arranged in the through hole above the frame 1. The threaded screw rod of the frame 1 penetrates through the first upper blade 21, and the threaded screw rod of the frame 1 is in threaded cooperation with the first upper blade 21. The threaded screw rod of the frame 1 is power-connected to the first planetary reducer 22. A first servo motor 23 is fixedly installed on the frame 1, and the first servo motor 23 is power-connected to the first planetary reducer 22.

[0043] Further, the inner top end of the through hole below the frame 1 is slidably fitted with a second upper blade 24. A second planetary reducer 25 is fixedly installed on the frame 1. A threaded rotating rod is arranged in the through hole below the frame 1. The threaded rotating rod of the frame 1 penetrates through the second upper blade 24, and the threaded rotating rod of the frame 1 is power-connected to the second planetary reducer 25. A second servo motor 26 is fixedly installed on the frame 1, and the second servo motor 26 is power-connected to the second planetary reducer 25. The upper cutter assembly 2001 includes the first upper blade 21 and the second upper blade 24.

[0044] Furthermore, the first planetary reducer 22 and the second planetary reducer 25 are planetary gear set reduction structures, used to reduce the rotational speed transmitted by the first servo motor 23 and the second servo motor 26, so as to drive the first upper blade 21 and the second upper blade 23 to move horizontally more precisely and improve the accuracy during equipment adjustment.

[0045] Among them, when adjusting the upper cutter assembly 2001, start the first servo motor 23 (the second servo motor 26). The first servo motor 23 (the second servo motor 26) drives the first planetary reducer 22 (the second planetary reducer 25) to operate. The first planetary reducer 22 (the second planetary reducer 25) drives the first upper blade 21 (the second upper blade 24) to move horizontally in the through hole above the frame 1 (the through hole below the frame 1), so as to adjust the size of the side clearance.

[0046] Further, the inner bottom ends of the through holes of the frame 1 are all rotatably fitted with lower auxiliary rods 27. Transverse plates 28 are rotatably fitted on the lower auxiliary rods 27. Upper auxiliary rods 29 are rotatably fitted on the transverse plates 28. A first lower blade 210 is arranged in the through hole above the frame 1, and the first lower blade 210 is rotatably fitted with the upper auxiliary rod 29, so that when the transverse plate 28 reciprocates horizontally, it drives the first lower blade 210 to move up and down reciprocally. A second lower blade 211 is arranged in the through hole below the frame 1, and the second lower blade 211 is rotatably fitted with the upper auxiliary rod 29, so that when the transverse plate 28 reciprocates horizontally, it drives the second lower blade 211 to move up and down reciprocally. The lower cutter assembly 2002 includes the first lower blade 210 and the second lower blade 211.

[0047] Furthermore, a first hydraulic rod 212 is fixedly installed on the frame 1. The first hydraulic rod 212 is adjacent to the through hole above the frame 1. The extending rod of the first hydraulic rod 212 penetrates the wall surface of the frame 1, and the extending rod of the first hydraulic rod 212 is rotatably engaged with the cross plate 28. A second hydraulic rod 213 is fixedly installed on the frame 1. The second hydraulic rod 213 is adjacent to the through hole below the frame 1. The extending rod of the second hydraulic rod 213 penetrates the wall surface of the frame 1, and the extending rod of the second hydraulic rod 213 is rotatably engaged with the cross plate 28.

[0048] Among them, when performing the shearing process, the first hydraulic rod 212 (the second hydraulic rod 213) is started. The first hydraulic rod 212 extends its extending rod to drive the cross plate 28 to move. Under the drive of the movement of the cross plate 28, the auxiliary rod 27 and the upper auxiliary rod 29 deflect simultaneously, so that the overall length of the lower auxiliary rod 27 and the upper auxiliary rod 29 first becomes longer and then shorter, enabling the upper auxiliary rod 29 to drive the first lower blade 210 (the second lower blade 211) to complete one up-and-down movement during the one-way movement of the cross plate 28. Thus, the first lower blade 210 (the second lower blade 211) completes one shearing process. Then, the first hydraulic rod 212 (the second hydraulic rod 213) retracts its extending rod to reset, enabling the first lower blade 210 (the second lower blade 211) to complete one up-and-down movement again. In this way, with the drive of the first hydraulic rod 212 (the second hydraulic rod 213), the first lower blade 210 (the second lower blade 211) forms a reciprocating operation.

[0049] Furthermore, a plurality of offset frames 214 are rotatably engaged on the frame 1. The offset frames 214 are symmetrically arranged up and down. The upper offset frame 214 is adjacent to the through hole above the frame 1, and the lower offset frame 214 is adjacent to the through hole below the frame 1. A first upper conveying roller 215 is rotatably engaged on the upper offset frame 214. A first lower conveying roller 216 is rotatably engaged on the frame 1. The first upper conveying roller 215 is directly above the first lower conveying roller 216. The bottom end of the movement track of the offset frame 214 driving the first upper conveying roller 215 to deflect is adjacent to the top end of the first lower conveying roller 216. A second upper conveying roller 217 is rotatably engaged on the lower offset frame 214. A second lower conveying roller 218 is rotatably engaged on the frame 1. The second upper conveying roller 217 is directly above the second lower conveying roller 218. The bottom end of the movement track of the offset frame 214 driving the second upper conveying roller 217 to deflect is adjacent to the top end of the second lower conveying roller 218. A plurality of rotating shaft motors 219 are fixedly installed on the frame 1, and each rotating shaft motor 219 is respectively power-connected to each offset frame 214.

[0050] When the steel strip is conveyed into the shearing machine, the steel strip is sent between the first upper conveying roller 215 and the first lower conveying roller 216 (between the second upper conveying roller 217 and the second lower conveying roller 218). The rotating shaft motor 219 is started, and the rotating shaft motor 219 drives the offset frame 214 to rotate. The offset frame 214 drives the first upper conveying roller 215 (the second upper conveying roller 217) to deflect, so that the first upper conveying roller 215 (the second upper conveying roller 217) presses the steel strip against the first lower conveying roller 216 (the second lower conveying roller 218). The first upper conveying roller 215 and the first lower conveying roller 216 (the second upper conveying roller 217 and the second lower conveying roller 218) guide the steel strip between the first upper blade 21 and the first lower blade 210 (the second upper blade 24 and the second lower blade 211).

[0051] Embodiment 3, as Figures 5 - 8 shown, the difference from the above embodiment is that the auxiliary mechanism 3 further includes a first support roller 31. The first support roller 31 is rotatably arranged beside the frame 1. A first auxiliary roller 32 is rotatably arranged beside the first support roller 31. The first support roller 31 and the first auxiliary roller 32 are adjacent and parallelly distributed. A second support roller 33 is rotatably arranged beside the frame 1. A second auxiliary roller 34 is rotatably arranged beside the second support roller 33. The second support roller 33 and the second auxiliary roller 34 are adjacent and parallelly distributed. The second support roller 33 and the second auxiliary roller 34 are located between the first auxiliary roller 32 and the frame 1. A plurality of first stepping motors 35 are fixedly arranged beside the frame 1. The first stepping motors 35 are respectively power-connected to the first support roller 31 and the second support roller 33.

[0052] Furthermore, the first stepping motor 35 is arranged at a position below the ground to prevent the first stepping motor 35 from affecting the placement of the steel strip coil.

[0053] Furthermore, a gear set is used to connect the first stepping motor 35 and the first support roller 31 (the second support roller 33). The gear on the shaft of the first support roller 31 (the second support roller 33) is larger in size than the gear on the shaft of the first stepping motor 35, so that its torque is larger and it can stably drive the steel coil to rotate.

[0054] Furthermore, a first guiding cover 36 is fixedly installed on the frame 1. One end of the first guiding cover 36 is adjacent to the first upper conveying roller 215, and the other end of the first guiding cover 36 is adjacent to the first auxiliary roller 32. A second guiding cover 37 is fixedly installed on the frame 1. One end of the second guiding cover 37 is adjacent to the second upper conveying roller 217, and the other end of the second guiding cover 37 is adjacent to the second auxiliary roller 34. A first sliding plate 38 is fixedly installed on the frame 1. The top end of the first sliding plate 38 is in contact with the bottom end of the through hole above the frame 1. The first sliding plate 38 and the first upper conveying roller 215 are respectively located on both sides of the frame 1. A second sliding plate 39 is fixedly installed on the frame 1. The top end of the second sliding plate 39 is in contact with the bottom end of the through hole below the frame 1. The second sliding plate 39 and the second upper conveying roller 217 are respectively located on both sides of the frame 1. A plurality of camera detectors 310 are fixedly arranged below the first sliding plate 38 and below the second sliding plate 39. The camera detectors 310 are used to detect the sheared steel strip.

[0055] First, place the steel coil on the first support roller 31 and the first auxiliary roller 32 (the second support roller 33 and the second auxiliary roller 34), and then start the first stepping motor 35. The first stepping motor 35 drives the first support roller 31 (the second support roller 33) to rotate. The first support roller 31 and the first auxiliary roller 32 (the second support roller 33 and the second auxiliary roller 34) cooperate to rotate the steel coil, so that the steel strip is wound out from the steel coil. The steel strip extends and is restricted by the first guiding cover 36 (the second guiding cover 37) to be conveyed between the first upper conveying roller 215 and the first lower conveying roller 216 (the second upper conveying roller 217 and the second lower conveying roller 218);

[0056] After that, after the steel strip is sheared, the sheared steel strip falls onto the first sliding plate 38 (the second sliding plate 39), and the camera detector 310 detects the shearing edge of the steel strip on the first sliding plate 38 (the second sliding plate 39).

[0057] Furthermore, a first cutter 311 is fixedly installed on the frame 1. The first cutter 311 is connected to the hydraulic oil circuit of the first hydraulic rod 212. A second cutter 312 is fixedly installed on the frame 1. The second cutter 312 is connected to the hydraulic oil circuit of the second hydraulic rod 213. The oil circuit cutting assembly 3001 includes the first cutter 311 and the second cutter 312. A plurality of sliding rods 313 are rotatably arranged beside the frame 1. The sliding rods 313 are respectively located between the first support roller 31 and the first auxiliary roller 32 and between the second support roller 33 and the second auxiliary roller 34. Moving platforms 314 are slidably engaged with the sliding rods 313. Screws 315 are rotatably arranged below the sliding rods 313. The screws 315 penetrate through the moving platforms 314. The screws 315 are in threaded cooperation with the moving platforms 314. Second stepping motors 316 are fixedly arranged beside the screws 315. The second stepping motors 316 are respectively power-connected to the screws 315.

[0058] Furthermore, an elastic tube is used to connect the oil circuits between the first cutter 311 (the second cutter 312) and the first hydraulic rod 212 (the second hydraulic rod 213), so that the first cutter 311 (the second cutter 312) does not affect the normal operation of the first hydraulic rod 212 (the second hydraulic rod 213).

[0059] Furthermore, the second stepper motor 316 is arranged below the ground to avoid the second stepper motor 316 affecting the placement of the steel strip coil.

[0060] Furthermore, the second stepper motor 316 is connected to the screw 315 by a gear set. The gear on the screw 315 shaft is larger than the gear on the second stepper motor 316 shaft, so that its torque is larger and it can stably drive the moving table 314 to drive the steel coil to move.

[0061] Among them, when burrs on the edge of the steel strip are detected, the camera detector 310 sends a signal to control the operation of the first servo motor 23 (the second servo motor 26) to adjust the side clearance of the first upper blade 21 (the second upper blade 24). When wavy edges appear on the edge of the steel strip, the limit clamping and guiding of the steel strip by the first upper conveying roller 215 and the first lower conveying roller 216 (the second upper conveying roller 217 and the second lower conveying roller 218) are first released. The camera detector 310 sends a signal to control the operation of the first cutter 311 (the second cutter 312), thereby stopping the operation of the first hydraulic rod 212 (the second hydraulic rod 213). Then the second stepper motor 316 is started. The second stepper motor 316 drives the screw 315 to rotate. The screw 315 drives the moving table 314 to move on the slide bar 313, so that the moving table 314 drives the steel strip coil to move to make the steel strip coil correspond to the shearing position, thereby eliminating the formation of wavy edges. Then the shearing machine continues to operate.

[0062] The working principle of the whole shearing machine:

[0063] Place the steel strip coil beside the frame 1, and then convey the steel strip from the steel strip coil into the through hole of the frame 1. When the steel strip passes through the frame 1 to the required length for shearing the steel strip, stop conveying the steel strip. Use the lower cutter assembly 2002 to press against the upper cutter assembly 2001 to shear the steel strip. The sheared steel strip will pass under the camera detector 310, and the camera detector 310 detects the shearing edge of the steel strip. When there are burrs on the shearing edge of the steel strip, immediately control the upper cutter assembly 2001 to move horizontally on the frame 1 to adjust the size of the side clearance, and complete the adjustment before the steel strip extends the required length again, so that the shearing machine does not need to stop to handle the burr problem on the shearing edge of the steel strip. When there are wavy edges on the shearing edge of the steel strip, the oil circuit cut-off assembly 3001 cuts off the power source supplied to the lower cutter assembly 2002, and then adjusts the position of the steel strip coil so that the three points of the unwinding position, shearing position, and winding position of the whole shearing machine are in a straight line, thereby eliminating the wavy edges generated on the shearing edge of the steel strip. Thus, when problems occur on the shearing edge of the steel strip, the equipment can be improved in time, the equipment problems can be automatically eliminated, the production of a large number of unqualified products can be avoided, manual operation for adjusting the equipment is replaced, and the production efficiency of the shearing machine is improved;

[0064] Among them, first place the steel coil on the first support roller 31 and the first auxiliary roller 32 (the second support roller 33 and the second auxiliary roller 34), and then start the first stepping motor 35. The first stepping motor 35 drives the first support roller 31 (the second support roller 33) to rotate. The first support roller 31 and the first auxiliary roller 32 (the second support roller 33 and the second auxiliary roller 34) cooperate to rotate the steel coil, so that the steel strip is wound out from the steel coil. The steel strip extends and is restricted by the first guide cover 36 (the second guide cover 37) to be conveyed between the first upper conveying roller 215 and the first lower conveying roller 216 (the second upper conveying roller 217 and the second lower conveying roller 218);

[0065] After the steel strip is sent between the first upper conveying roller 215 and the first lower conveying roller 216 (between the second upper conveying roller 217 and the second lower conveying roller 218), start the rotating shaft motor 219. The rotating shaft motor 219 drives the offset frame 214 to rotate, and the offset frame 214 drives the first upper conveying roller 215 (the second upper conveying roller 217) to deflect, so that the first upper conveying roller 215 (the second upper conveying roller 217) presses the steel strip against the first lower conveying roller 216 (the second lower conveying roller 218). The first upper conveying roller 215 and the first lower conveying roller 216 (the second upper conveying roller 217 and the second lower conveying roller 218) guide the steel strip between the first upper blade 21 and the first lower blade 210 (the second upper blade 24 and the second lower blade 211);

[0066] When performing the shearing process, the first hydraulic rod 212 (the second hydraulic rod 213) is activated. The first hydraulic rod 212 extends its rod to drive the transverse plate 28 to move. The movement of the transverse plate 28 drives the lower auxiliary rod 27 and the upper auxiliary rod 29 to deflect simultaneously, so that the overall length of the lower auxiliary rod 27 and the upper auxiliary rod 29 first becomes longer and then shorter. This enables the upper auxiliary rod 29 to drive the first lower blade 210 (the second lower blade 211) to complete one up-and-down movement during a one-way movement of the transverse plate 28. Thus, the first lower blade 210 (the second lower blade 211) completes one shearing process. Then, the first hydraulic rod 212 (the second hydraulic rod 213) retracts its rod to reset, causing the first lower blade 210 (the second lower blade 211) to complete another up-and-down movement. In this way, with the drive of the first hydraulic rod 212 (the second hydraulic rod 213), the first lower blade 210 (the second lower blade 211) forms a reciprocating operation;

[0067] Afterwards, after the steel strip is sheared, the sheared steel strip falls onto the first sliding plate 38 (the second sliding plate 39), and the camera detector 310 detects the shearing edge of the steel strip on the first sliding plate 38 (the second sliding plate 39);

[0068] When detecting burrs on the edge of the steel strip, the camera detector 310 sends a signal to control the operation of the first servo motor 23 (the second servo motor 26) to adjust the size of the side clearance of the first upper blade 21 (the second upper blade 24). When adjusting the upper cutting tool assembly 2001, the first servo motor 23 (the second servo motor 26) is activated. The first servo motor 23 (the second servo motor 26) drives the first planetary reducer 22 (the second planetary reducer 25) to operate. The first planetary reducer 22 (the second planetary reducer 25) drives the first upper blade 21 (the second upper blade 24) to horizontally move in the through-hole above the frame 1 (the through-hole below), thereby adjusting the size of the side clearance;

[0069] When detecting wavy edges on the edge of the steel strip, first release the limit clamping and guiding of the steel strip by the first upper conveying roller 215 and the first lower conveying roller 216 (the second upper conveying roller 217 and the second lower conveying roller 218). The camera detector 310 sends a signal to control the operation of the first cutter 311 (the second cutter 312), thereby stopping the operation of the first hydraulic rod 212 (the second hydraulic rod 213). Then, start the second stepping motor 316. The second stepping motor 316 drives the screw 315 to rotate. The screw 315 drives the moving table 314 to move on the sliding rod 313, so that the moving table 314 drives the steel strip coil to move, making the steel strip coil correspond to the shearing position, thereby eliminating the formation of wavy edges. Then, the shearing machine continues to operate.

[0070] A shearing method based on edge side clearance adjustment uses the above automatic shearing machine and includes the following steps:

[0071] S1: Place the steel strip coil on the first support roller 31 and the first auxiliary roller 32. Similarly, when performing multi-station processing, place it on the second support roller 33 and the second auxiliary roller 34.

[0072] S2: The first support roller 31 drives the steel strip coil to rotate to send the steel strip between the first upper blade 21 and the first lower blade 210 for shearing.

[0073] S3: The camera detector 310 detects the sheared steel strip.

[0074] S4: When there are burrs on the edge of the sheared steel strip, adjust the side clearance of the first upper blade 21. When there are wavy edges on the edge of the sheared steel strip, the first cutter 311 controls the first lower blade 210 to stop running and adjusts the position of the steel strip coil on the first support roller 31 and the first auxiliary roller 32.
