[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 11 As shown, a bending machine that can meet different bending requirements includes the following embodiments: Embodiment 1: comprising a bending machine device 1, wherein a bending die 3 is fixedly connected to the bottom end of the bending machine device 1, a bending knife 2 is arranged at the top end of the bending machine device 1, a hydraulic telescopic cylinder 201 is fixedly connected to the top end of the bending machine device 1, and the output end of the hydraulic telescopic cylinder 201 is fixedly connected to the bending knife 2, and further comprising: A support plate 4, both sides of which are fixedly connected with rotating arms 401, the two rotating arms 401 are respectively rotatably connected to the bending machine equipment 1, two auxiliary clamping plates 402 are arranged on the top of the support plate 4, and a driving member is arranged on the top of the support plate 4 for driving the two auxiliary clamping plates 402 to clamp the two sides of the workpiece; The connecting tube 6 has lubrication tubes 601 fixedly connected at both ends thereof, and multiple nozzles 602 for spraying lubrication on the workpieces are fixedly connected to the outsides of the two lubrication tubes 601. The nozzles 602 are bent in advance, and seals are slidably connected inside the two lubrication tubes 601. A connecting piece is provided between the seal and the auxiliary clamping plate 402, and the auxiliary clamping plate 402 drives the seal to slide inside the lubrication tube 601 through the connecting piece, thereby adjusting the spraying range of the lubrication tube 601 according to workpieces of different sizes.

[0026] The driving member includes a bidirectional screw rod 403 that passes through the support plate 4 and is rotatably connected to the support plate 4. The bidirectional screw rod 403 passes through two auxiliary clamping plates 402 and is connected to the auxiliary clamping plates 402 through a ball nut pair. A limiting rod 404 is fixedly connected inside the support plate 4. The limiting rod 404 passes through the auxiliary clamping plate 402 and is slidably connected to the auxiliary clamping plate 402. A second motor is fixedly connected to the outside of the support plate 4, and the output shaft of the second motor is fixedly connected to the bidirectional screw rod 403.

[0027] During specific implementation, in the actual production process, in order to ensure the use of lubricating oil when using a bending machine and a mold for processing during the bending process of metal and other material products. Lubricating oil can reduce the friction coefficient and friction force on the contact arc surface of the deformation zone, thereby reducing the total rolling pressure and energy consumption, increasing the rolling speed, and reducing the wear of the rollers, and preventing the metal from sticking to the rollers. The existing lubricating liquid is generally sprayed on the bending knife 2, and then squeezed on the bend by the bending knife 2. However, due to the different sizes of the workpieces, only part of the lubricating oil is in contact with the workpiece, so a large amount of lubricating oil is caused to drip on the bending machine equipment 1, causing a lot of waste, and it is impossible to automatically adjust according to different sizes. Therefore, in this solution, the workpiece is first placed on the bending mold 3 where it needs to be bent, and then the workpiece is pressed by the bending mold 3. By starting the driving member, the two auxiliary clamping plates 402 are driven to clamp and support the two sides of the workpiece; when the auxiliary clamping plate 402 moves, the sealing member is driven to move inside the lubrication tube 601 through the connecting member, and the spray range of the nozzle 602 outside the lubrication tube 601 is adjusted according to the size of the workpiece to lubricate the bending part of the workpiece, and finally the hydraulic telescopic cylinder 201 is started, and the hydraulic telescopic cylinder 201 pushes the bending knife 2 down to bend the workpiece, thereby ensuring that during the plate bending process, the friction resistance can be reduced by lubrication, making the bending process smoother, and it can be used when bending plates of different sizes.

[0028] like Figure 2 As shown, in this embodiment, a storage cylinder 603 is fixedly connected to the top of the bending machine equipment 1, a delivery pump is arranged inside the storage cylinder 603, an output end of the delivery pump is fixedly connected to a liquid infusion tube 604, and the liquid infusion tube 604 is fixedly connected to the connecting cylinder 6.

[0029] In specific implementation, by starting the storage cylinder 603 and the delivery pump inside the storage cylinder 603, the lubricating liquid inside the storage cylinder 603 is delivered to the connecting cylinder 6 through the delivery tube 604, and then the nozzle 602 set on the lubricating tube 601 is used to spray lubrication on the bending part of the workpiece.

[0030] like Figures 9 to 11 As shown, embodiment 2: the seal includes a rotating ring 6011 that fits with the inner wall of the lubrication tube 601, a magnetic ring 6012 is rotatably connected inside the rotating ring 6011, a sealing plate 6013 is fixedly connected inside the magnetic ring 6012, a plurality of baffles 6014 are arranged inside the lubrication tube 601, the plurality of baffles 6014 are arranged on the outside of the rotating ring 6011 and are slidably connected to the rotating ring 6011, a plurality of baffles 6014 are fixedly connected with an impeller 6015 near one end of the connecting tube 6, the impeller 6015 is rotatably connected to the inner wall of the lubrication tube 601, and when the lubricating fluid enters the rear lubrication tube 601 and passes through the impeller 6015, it drives the impeller 6015 to rotate.

[0031] In specific implementation, when the lubricating liquid enters the lubrication tube 601 through the connecting tube 6, it first contacts the impeller 6015 inside the lubrication tube 601, and the flow of liquid drives the impeller 6015 to rotate. When the impeller 6015 rotates, it drives multiple baffles 6014 fixedly connected to the outside to rotate. The baffle 6014 is arranged on the outside of the rotating ring 6011, and then drives the rotating ring 6011 to rotate. At this time, the multiple baffles 6014 rotate to intermittently block the connection between the lubrication tube 601 and the nozzle 602, so that the nozzle 602 sprays intermittently, thereby saving the use of lubricating liquid while ensuring the spraying process.

[0032] like Figure 5 , Figure 8 and Fig.11 As shown, in this embodiment: the connecting part includes a sliding frame 7 fixedly connected to the outside of the bending machine equipment 1, and two sliding seats 701 are slidably connected to the outside of the sliding frame 7. The tops of the two sliding seats 701 are fixedly connected with open annular plates 702, and the open annular plates 702 are sleeved on the outside of the lubrication pipe 601. The inner wall of the open annular plate 702 is fixedly connected with a magnet ring, and the magnet ring is magnetically adsorbed to the magnetic attraction ring 6012.

[0033] The connecting part also includes an arc plate 703 fixedly connected to the bottom of the auxiliary clamping plate 402, a contact plate 704 is fixedly connected to the outer side of the arc plate 703, a sliding groove is opened on the side of the sliding seat 701 close to the auxiliary clamping plate 402, the contact plate 704 extends to the inside of the sliding groove outside the sliding seat 701, and is slidably connected to the sliding seat 701.

[0034] During specific implementation, when the two auxiliary clamping plates 402 are driven by the driving member to approach each other, the two sides of the workpiece are clamped and contacted, the arc plate 703 fixedly connected to the bottom of the auxiliary clamping plate 402 drives the sliding seat 701 to slide on the outside of the sliding frame 7. Due to the open annular plate 702 fixedly connected to the top of the sliding seat 701, the magnet ring inside the open annular plate 702 is magnetically attracted to the magnetic ring 6012. When the open annular plate 702 moves, the magnetic ring 6012 is driven to slide inside the lubrication tube 601 by magnetic attraction. The inside of the lubrication tube 601 is blocked by the rotating ring 6011, the magnetic ring 6012 and the sealing plate 6013, so that the range of spray lubrication can be automatically adjusted according to workpieces of different sizes, thereby avoiding waste and improving the utilization rate of the lubricating fluid.

[0035] like Figures 3 to 5 As shown, embodiment three: both sides of the bending machine equipment 1 are rotatably connected with a rotating shaft 501, the outer side of the rotating shaft 501 is fixedly connected with a transmission gear 502 and a winding disk 503, both sides of the bending knife 2 are fixedly connected with a rack 507, the rack 507 is meshed with the transmission gear 502, a connecting tube 505 is sleeved on the outer side of the rotating shaft 501, the connecting tube 505 is fixedly connected to the bending machine equipment 1, a torsion spring 506 is fixedly connected between the connecting tube 505 and the rotating shaft 501, a traction rope 504 is fixedly connected to the outer side of the winding disk 503, and the other end of the traction rope 504 is fixedly connected to the support plate 4, and a guide wheel is fixedly connected to the top of the inside of the bending machine equipment 1, and the traction rope 504 passes through the guide wheel.

[0036] During specific implementation, when the hydraulic telescopic cylinder 201 pushes the bending knife 2 to descend, the racks 507 fixedly connected on both sides of the bending knife 2 mesh with the transmission gear 502 as the bending knife 2 is pressed down to bend, and the transmission gear 502 drives the fixedly connected rotating shaft 501 to rotate, and the rotation of the rotating shaft 501 drives the fixedly connected winding disk 503 to rotate, and the winding disk 503 winds up the traction rope 504, so that the support plate 4 is pulled by the traction rope 504 to deflect as the workpiece is bent, support the workpiece, avoid manual assistance, and support the workpiece by supporting the support plate 4. The bending is more stable and suitable for different required bending angles. When the support plate 4 is in a horizontal state, the support plate 4 is supported by the traction rope 504 and the arc plate 703. When the workpiece is bent, the rear end of the plate is often manually held to make the rear end of the workpiece tilted. In this solution, the workpiece is supported by the support plate 4, which avoids manual hand support and ensures the safety of the operator.

[0037] like Figure 7As shown, in this embodiment, the top of the auxiliary clamping plate 402 is fixedly connected to a fixed cylinder 4021, the inside of the fixed cylinder 4021 is slidably connected to an electromagnet 4024, the bottom of the electromagnet 4024 is fixedly connected to a downward pressure rod 4023, the downward pressure rod 4023 penetrates the fixed cylinder 4021 and is slidably connected to the fixed cylinder 4021, a return spring 4025 is fixedly connected between the electromagnet 4024 and the fixed cylinder 4021, the top of the auxiliary clamping plate 402 is fixedly connected to a supplementary cylinder 4026, a connecting tube is fixedly connected between the supplementary cylinder 4026 and the fixed cylinder 4021, and a magnetic fluid is filled between the fixed cylinder 4021 and the electromagnet 4024. When the electromagnet 4024 is energized, magnetism is generated to solidify the magnetic fluid.

[0038] In specific implementation, when the two auxiliary clamping plates 402 clamp the two sides of the workpiece respectively, the downward pressure rod 4023 inside the auxiliary clamping plate 402 contacts the top of the workpiece. Since the top of the downward pressure rod 4023 is fixedly connected with an electromagnet 4024, the electromagnet 4024 is arranged inside the fixed cylinder 4021, and the fixed cylinder 4021 is filled with magnetic fluid. The magnetic fluid is a mixture of magnetic solid particles, base carrier liquid and surfactant to form a stable colloidal liquid. When there is no external magnetic field, the magnetic fluid has no magnetic attraction; but when an external magnetic field acts, it will show magnetism and change its shape as the magnetic field changes. Therefore, the lower pressure rod 4023 can move according to workpieces of different thicknesses. When the workpiece needs to be clamped, the electromagnet 4024 is energized, and magnetism is generated. The magnetic fluid inside the fixed cylinder 4021 solidifies, allowing the lower pressure rod 4023 to stably clamp the workpiece. The workpiece can be clamped according to different sizes, and when the support plate 4 rotates, the workpiece is guaranteed to be stable during bending to avoid bending errors caused by shaking of the workpiece.

[0039] When the lower pressure rod 4023 rises, the magnetic fluid in the fixed cylinder 4021 is squeezed into the electromagnet 4024 , and when the lower pressure rod 4023 descends, the magnetic fluid enters the fixed cylinder 4021 through the supplementary cylinder 4026 .

[0040] like Figures 5 and 6 As shown, embodiment four: the two auxiliary clamping plates 402 are rotatably connected to the pushing wheel 405, and a rotating rod 406 is arranged inside the supporting plate 4. The rotating rod 406 passes through the pushing wheel 405 in sequence and is movably connected to the pushing wheel 405. A limiting groove is provided on the outer side of the rotating rod 406. A protrusion is fixedly connected to the inside of the pushing wheel 405. The protrusion extends to the inside of the limiting groove provided on the outer side of the rotating rod 406 and is slidably connected to the rotating rod 406. A first motor is fixedly connected to the outer side of the supporting plate 4, and the output shaft of the first motor is fixedly connected to the rotating rod 406.

[0041] In specific implementation, when it is necessary to further bend other positions of the workpiece, the electromagnet 4024 is powered off to release the fixation of the workpiece. At this time, the first motor is started again, and the output shaft of the first motor drives the rotating rod 406 to rotate. The rotating rod 406 cooperates with the protrusion of the pushing wheel 405 through the limiting groove, driving the pushing wheel 405 to rotate, thereby pushing the workpiece to move and adjusting the bending position of the workpiece.

[0042] A method for using the bending machine is also provided, comprising the following steps: Step 1: First, the workpiece to be bent is placed on the bending die 3, and the two auxiliary clamping plates 402 are driven by the start-up drive to clamp and support both sides of the workpiece; Step 2: When the auxiliary clamping plate 402 moves, the seal is driven to move inside the lubrication tube 601 through the connecting piece, and the spray range of the nozzle 602 outside the lubrication tube 601 is adjusted according to the size of the workpiece to lubricate the bending part of the workpiece.

[0043] Step 3: Finally, the hydraulic telescopic cylinder 201 is started, and the hydraulic telescopic cylinder 201 pushes the bending knife 2 down, thereby bending the workpiece.
