Description

Technical Field

[0002] Metal sheets are metal materials processed into flat or nearly flat plates with a certain thickness, width and length through rolling, casting, forging and other processes. They are one of the important forms of metal materials. Metal sheet cutting is the process of cutting or splitting metal sheets into the required size and shape.

[0003] A Chinese patent with announcement number CN113070526B discloses a uniform segmented cutting device for stainless steel plates for outdoor construction. The device is provided with a clamping mechanism and a positioning mechanism. The clamping mechanism can clamp the stainless steel plate, and the positioning mechanism can correct the position of the stainless steel plate to prevent the stainless steel plate from tilting.

[0004] However, after cutting the steel plates, the above-mentioned equipment cannot polish or remove rust from the surface of the steel plates, and needs to be transferred to polishing equipment for secondary polishing, which reduces the processing efficiency of the steel plates. In addition, a large amount of debris will be generated in the process of cutting the steel plates.

[0045] Example

[0046] See also Figures 1 to 10This embodiment provides an integrated metal plate cutting and polishing device, including a cutting mechanism, a polishing mechanism 5 and a dust collecting mechanism 7.

[0047] Wherein, the cutting mechanism is used to cut the metal sheet;

[0048] The polishing mechanism 5 is used to polish the top and bottom of the divided metal sheet at the same time;

[0049] The dust collecting mechanism 7 is used to collect the debris generated by cutting by the cutting mechanism and the debris generated by polishing by the polishing mechanism 5 .

[0050] In this embodiment, the cutting mechanism includes a first conveyor belt 1, an X-axis linear module 2 and a Y-axis linear module 3. The first conveyor belt 1 is used to convey the metal sheet to be cut. The X-axis linear module 2 is installed at the discharge port of the first conveyor belt 1 through a column. The Y-axis linear module 3 is installed on the slide of the X-axis linear module 2. A laser cutting head 8 is fixed on the slide of the Y-axis linear module 3.

[0051] By adopting the cutting mechanism of the above technical solution, when in use, the metal sheet to be cut is placed on the first conveyor belt 1, and then transported to the laser cutting head 8 through the first conveyor belt 1, and then the Y-axis linear module 3 is controlled to drive the laser cutting head 8 to move downward, so that the laser cutting head 8 moves to a certain distance from the top of the metal sheet, and then the X-axis linear module 2 is controlled to drive the laser cutting head 8 to cut the metal sheet along the X-axis direction.

[0052] In this embodiment, the polishing mechanism 5 includes a cabinet 501 and a polishing assembly. The polishing assembly is provided in two groups. The two groups of polishing assemblies are distributed in the cabinet 501 in an upper and lower manner. The polishing assembly located at the upper side is used to polish the top of the divided metal sheet, and the polishing assembly located at the lower side is used to polish the bottom of the divided metal sheet.

[0053] Both polishing mechanisms include a first support plate 502, which is fixedly connected to the inside of the cabinet 501, a first electric push rod 503 is fixedly installed on the first support plate 502, a first mounting frame 504 is fixedly connected to the piston rod end of the first electric push rod 503, a polishing roller 505 is rotatably installed on the inner side of the first mounting frame 504, a polishing motor 506 for driving the first mounting frame 504 to rotate is fixedly installed on one side of the first mounting frame 504, a first guide rod 507 is fixedly connected to the first mounting frame 504, and an end of the first guide rod 507 away from the first mounting frame 504 slides through the first support plate 502;

[0054] A second conveyor belt 4 and a third conveyor belt 6 are respectively arranged on both sides of the polishing component. The second conveyor belt 4 is used to convey the divided metal sheets to the polishing component for polishing. The third conveyor belt 6 is used to move the polished metal sheets out of the cabinet 501. Extrusion components are arranged on both sides of the polishing component inside the cabinet 501. The extrusion components are used to limit the metal sheets in the polishing state. The extrusion components include a second support plate 509, which is fixedly connected to the inside of the cabinet 501. A second electric push rod 508 is fixedly installed on the top of the second support plate 509. The bottom of the piston rod of the second electric push rod 508 is fixedly connected to a second mounting frame 510. A pressure roller 511 is rotatably installed on the inner side of the second mounting frame 510.

[0055] By adopting the polishing mechanism 5 of the above technical solution, when in use, the divided metal sheet is moved between the two polishing rollers 505 through the second conveyor belt 4, and then the piston rod of the first electric push rod 503 is controlled to extend, so that the polishing roller 505 is pressed on the surface of the metal sheet, and then the piston rod of the second electric push rod 508 is controlled to extend, so that the pressure roller 511 is pressed on the top of the metal sheet to avoid the metal sheet from moving during polishing. At this time, the metal sheet moves slowly along the second conveyor belt 4 toward the direction of the third conveyor belt 6, and the polishing motor 506 is controlled to start, thereby driving the polishing roller 505 to rotate. The rotating polishing roller 505 polishes the top and bottom of the metal sheet at the same time, and the polished metal sheet is moved out of the cabinet 501 through the third conveyor belt 6.

[0056] In this embodiment, the dust collecting mechanism 7 includes a negative pressure box 701, a dust collecting pipe 9 for collecting debris generated by cutting by the cutting mechanism, and a dust collecting hood 10 for collecting debris generated by polishing by the polishing mechanism 5. The slide of the Y-axis linear module 3 is fixedly connected with a fixed seat 301, one end of the dust collecting pipe 9 is fixedly installed on the fixed seat 301, and the other end of the dust collecting pipe 9 is connected to the lower end of the negative pressure box 701. Two dust collecting hoods 10 are provided, and the two dust collecting hoods 10 are respectively arranged at the feed port and the discharge port of the cabinet 501. The dust collecting hood 10 is connected to the lower end of the interior of the negative pressure box 701 through a pipeline. A negative pressure fan 702 is fixedly installed on the top of the negative pressure box 701. The interior of the negative pressure box 701 is provided with an electrostatic adsorption component for adsorbing debris entering the negative pressure box 701, and the electrostatic adsorption component includes corona electrodes 705 and dust collecting electrodes 706 which are alternately arranged.

[0057] By adopting the dust collecting mechanism 7 of the above technical solution, when in use, the negative pressure fan 702 is started to form a negative pressure inside the negative pressure box 701, and the debris enters the negative pressure box 701 through the dust collecting pipe 9 and the dust collecting cover 10. The air is ionized by the corona electrode 705, and the ionized air collides with the debris entering the negative pressure box 701, so that the debris is charged. Under the action of the electric field force, the charged debris particles move toward the dust collecting electrode plate 706 with opposite polarity. When the debris particles reach the dust collecting electrode plate 706, they are adsorbed on the dust collecting electrode plate 706 due to the action of the electrostatic force.

[0058] Among them, the interior of the negative pressure box 701 is provided with a dust scraping assembly for scraping off the debris adsorbed on the electrostatic adsorption assembly, the dust scraping assembly includes a scraper 711, and a plurality of through holes 7110 are opened on the scraper 711. The scraper 711 is slidably mounted on the corona electrode 705 and the dust collecting electrode 706 through the through holes 7110. The bottom sides of the scraper 711 are hinged with collecting plates 7113, and the top of the collecting plate 7113 is fixedly connected with a first hanging ring, and the side of the scraper 711 is fixedly connected with a second hanging ring. The first hanging ring and the second hanging ring are connected by a reset spring 7114. The interior of the negative pressure box 701 is provided with a dust scraping assembly for driving the dust scraping assembly to move back and forth along the length direction of the electrostatic adsorption assembly. The driving assembly includes a driving motor 708 and a screw rod 709. The driving motor 708 is fixedly installed on one side outer wall of the negative pressure box 701. The screw rod 709 is rotatably installed inside the negative pressure box 701. One end of the screw rod 709 rotates through the negative pressure box 701 through a sealed bearing and is fixedly connected to the rotating shaft of the driving motor 708. The top of the scraper 711 is fixedly connected with a first connecting sleeve 7111, and the first connecting sleeve 7111 is threadedly rotatably sleeved on the screw rod 709. The top of the scraper 711 is fixedly connected with a second connecting sleeve 7112. The inside of the negative pressure box 701 is fixedly connected with a second guide rod 710, and the second connecting sleeve 7112 is slidably sleeved on the second guide rod 710.

[0059] By adopting the above technical solution, when in use, the rotation shaft of the driving motor 708 is controlled to rotate, thereby driving the screw rod 709 to rotate. The rotating screw rod 709 drives the scraper 711 to move along the length direction of the electrostatic adsorption component to scrape off the debris adsorbed on the dust collecting plate 706. The scraped debris is concentrated on the collection plate 7113.

[0060] In order to discharge the debris on the collecting plate 7113 to the outside, collecting ports 7011 are provided on the opposite sides of the negative pressure box 701, and dust collecting boxes 703 are installed at the collecting ports 7011. The upper end of the dust collecting box 703 is connected to the collecting port 7011, and both ends of the corona electrode 705 and the two ends of the dust collecting electrode 706 are fixedly connected with insulating connecting plates 707, and the insulating connecting plates 707 are fixedly installed inside the dust collecting box 703. One end of the insulating connecting plate 707 away from the dust collecting box 703 extends into the negative pressure box 701, and the scraper 711 can be slidably mounted on the insulating connecting plate 707. A third electric push rod 712 is fixedly installed on the top of the dust collecting box 703. The collecting plate 7113 in the dust scraping assembly passes through the collecting After the opening 7011 completely enters the dust box 703, the piston rod of the third electric push rod 712 is controlled to extend, so that the collecting plate 7113 is flipped downward, and the debris on the collecting plate 7113 falls into the dust box 703. At this time, the scraper 711 blocks the collecting opening 7011, so that the dust box 703 and the negative pressure box 701 are in a separated state. A proximity sensor 713 for monitoring whether the collecting plate 7113 enters the dust box 703 is fixedly installed inside the dust box 703. A PLC controller is installed on the negative pressure box 701. The third electric push rod 712 and the drive motor 708 are both controlled by the PLC controller, and the proximity sensor 713 is electrically connected to the signal input end of the PLC controller.

[0061] In this embodiment, the proximity sensor 713 adopts an Omron proximity switch of model E2B-S08KN04-WP-C1, and the PLC controller adopts Siemens S7-300 series PLC control.

[0062] By adopting the above technical solution, when the collecting plate 7113 moves into the dust box 703, the proximity sensor 713 detects the collecting plate 7113 and transmits a signal to the PLC controller. The PLC controller controls the piston rod of the third electric push rod 712 to extend, so that the collecting plate 7113 flips downward, thereby causing the debris on the collecting plate 7113 to fall into the dust box 703. Then the PLC controller controls the piston rod of the third electric push rod 712 to retract. At this time, the collecting plate 7113 is reset under the elastic force of the reset spring 7114. When the collecting plate 7113 enters the dust box 703, the scraper 711 slides on the insulating connecting plate 707. Therefore, the debris on the collecting plate 7113 is no longer affected by electrostatic adsorption and can fall smoothly into the dust box 703.

[0063] The PLC controller implements an intelligent control strategy based on a dynamic debris removal efficiency model, which satisfies:

[0064]

[0065] The parameters are defined as:

[0066] η(t): real-time removal efficiency threshold (set value ≥ 90%);

[0067] v: the speed conversion of the driving motor 708 (0.01-0.05m / s);

[0068] E: Field intensity regulation between corona electrode 705 and dust collecting electrode 706 (5-12 kV / cm);

[0069] u: frequency conversion control wind speed of negative pressure fan 702 (0.8-1.5m / s);

[0070] ρ: Plate debris density database value pre-stored in PLC;

[0071] m: real-time debris accumulation amount fed back by proximity sensor 713;

[0072] A: Geometric area setting value of dust collecting plate 706;

[0073] α=0.78,β=1.25,γ=0.33: Equipment constants calibrated by orthogonal experiment;

[0074] τ: Scraper 711 movement response time constant (8-15s).

[0075] For example, when processing a 2mm thick stainless steel plate, the PLC controller:

[0076] 1. Retrieve ρ=7.9g / cm from the database 3 ;

[0077] 2. Receive proximity sensor data m = 18g / m 2 ;

[0078] 3. Set A = 0.8m 2 , calculate ln(1+18 / 0.8)=3.12;

[0079] 4. According to the preset α=0.78, β=1.25, γ=0.33;

[0080] 5. Dynamic adjustment v = 0.028m / s, E = 9.5kV / cm, u = 1.1m / s;

[0081] 6. When t = 25s, calculate η(25s) = 91.4%, and continue scraping until η(t) ≥ 90%.

[0082] Technical effects:

[0083] Debris removal response time is significantly reduced;

[0084] The fluctuation range of energy consumption is significantly reduced;

[0085] The electric field intensity and mechanical motion are dynamically decoupled and controlled.

[0086] Working principle process:

[0087] Debris accumulation monitoring → parameter database call → real-time equation solution → multi-actuator collaborative control → clearing efficiency feedback calibration.

[0088] Among them, the execution logic of the intelligent control strategy includes:

[0089] a) When m / A>0.2, the η(t) calculation module is automatically triggered to prioritize increasing v to the critical speed

[0090]

[0091] b) When detected When , a scraping stop instruction is generated and the third electric push rod 712 is activated;

[0092] c) Dynamic compensation for differences in chip adhesion coefficients for different plates based on the term γ·ln(1+m / A)

[0093] d) Through 1-et / τ The optimal scraping duration is predicted by the term and the current operation cycle is terminated forcibly when t>3τ.

[0094] Critical velocity formula to ensure that the debris stripping velocity matches the critical value of electric field adsorption;

[0095] The efficiency change rate threshold indicates that the cleaning process has entered the stage of diminishing marginal benefits.

[0096] For example, aluminum alloy processing scenario:

[0097] 1. When m / A=0.25>0.2, it will be automatically calculated.

[0098] 2. Increase the speed of the drive motor to the corresponding v = 0.04m / s;

[0099] 3. Real-time monitoring When the value is detected to drop to 0.008s -1 hour:

[0100] Stop the scraper from moving;

[0101] Activate the third electric push rod to perform flip unloading;

[0102] 4. The ln(1+m / A) term is used to compensate for the low adhesion characteristics of aluminum alloy debris and automatically reduce E to 6.8 kV / cm.

[0103] Technical effect: It avoids plate wear caused by excessive scratching, greatly shortens the self-adaptation time of debris removal parameters of different materials, and significantly reduces the energy consumption of a single operation through marginal benefit control.

[0104] Working principle process:

[0105] Threshold judgment → critical speed calculation → dynamic parameter adjustment → efficiency change rate monitoring → job termination decision.

[0106] Among them, the working voltage of the corona electrode 705 is implemented in a closed-loop control to meet the following requirements:

[0107]

[0108] Where:

[0109] V 0 : Base voltage (linearly related to E), V 0 =1.2E·d: basic voltage (d is the distance between the plates 0.15m);

[0114] Technical effects:

[0115] The debris migration rate is significantly improved, the partial discharge of the plate is greatly reduced, and the phase synchronization with the scraper movement makes the difference in debris accumulation density smaller.

[0116] Working principle process:

[0117] Scraper displacement detection → sine wave phase calculation → high voltage power supply modulation → debris directional migration → coordinated scraping operation.

[0118] This voltage fluctuation mode causes the debris to migrate in a directional manner on the surface of the dust collecting electrode 706 , and the migration direction is consistent with the movement direction of the scraper 711 .

[0119] In order to facilitate the cleaning of the debris in the dust box 703, a cleaning port is opened at the lower end of the dust box 703, and a cleaning door panel 704 is hinged in the cleaning port. The cleaning door panel 704 is a transparent door panel. The debris in the dust box 703 can be observed through the transparent door panel.

[0120] In order to prevent debris entering the negative pressure box 701 from passing through the gap of the insulating connecting plate 707, a guide plate 714 is fixedly installed inside the negative pressure box 701, and the guide plate 714 is arranged below the electrostatic adsorption component.

[0121] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below.

[0122] Working principle: When in use, the metal sheet to be cut is placed on the first conveyor belt 1, and then conveyed to the laser cutting head 8 through the first conveyor belt 1, and then the Y-axis linear module 3 is controlled to drive the laser cutting head 8 to move downward, so that the laser cutting head 8 moves to a certain distance from the top of the metal sheet, and then the X-axis linear module 2 is controlled to drive the laser cutting head 8 to cut the metal sheet along the X-axis direction, and the divided metal sheet is moved between the two polishing rollers 505 through the second conveyor belt 4, and then the piston rod of the first electric push rod 503 is controlled to extend, so that the polishing roller 505 is pressed on the surface of the metal sheet, and then the piston rod of the second electric push rod 508 is controlled to extend, so that the pressure roller 511 is pressed on the top of the metal sheet to avoid the metal sheet from moving during polishing. At this time, the metal sheet moves slowly along the second conveyor belt 4 toward the direction of the third conveyor belt 6, and at the same time, the polishing motor 506 is controlled to start, thereby driving the polishing roller 505 to rotate, and the rotating polishing roller 505 polishes the top and bottom of the metal sheet at the same time, and the polished metal sheet is moved out of the cabinet 501 through the third conveyor belt 6.

[0123] During cutting and polishing, the negative pressure fan 702 is started to form a negative pressure inside the negative pressure box 701, and the debris enters the negative pressure box 701 through the dust collecting pipe 9 and the dust collecting hood 10. The air is ionized by the corona electrode 705. The ionized air collides with the debris entering the negative pressure box 701, so that the debris is charged. Under the action of the electric field force, the charged debris particles move toward the dust collecting plate 706 with opposite polarity. When the debris particles reach the dust collecting plate 706, they are adsorbed on the dust collecting plate 706 due to the action of the electrostatic force.

Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
