Description

Technical Field

[0002] Aluminum sheet refers to a plate material made of aluminum or aluminum alloy, usually made from aluminum ingots through plastic processing methods such as rolling, extrusion, stretching and forging, and has good physical and chemical properties; After the aluminum sheet is produced, it is generally necessary to perform longitudinal cutting on the produced aluminum sheet, mainly to meet specific usage requirements, such as specific width and size, to optimize material utilization, improve production efficiency, and facilitate subsequent processing; Longitudinal cutting can ensure the precise size of aluminum plates, smooth edges, improve the overall aesthetics of the product, and help improve processing efficiency and material utilization. When longitudinally cutting aluminum profiles, the aluminum profiles are generally released and cut with a longitudinal cutting knife. However, when the slitting knife is used to cut the aluminum profile for a long time, the blade of the slitting knife may be worn, which affects the cutting accuracy and efficiency, and causes the gap of the aluminum profile cutting to become larger, resulting in waste of the aluminum profile.

[0021] Embodiment 2 Based on Example 1, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 , Specifically, a fixed plate 19 is connected between the two support plates 4, and three limiting grooves 20 are opened on the fixed plate 19. Both sides of the three limiting grooves 20 are rotatably connected with shaking plates 22 through rotating blocks 21. The bottoms of the two shaking plates 22 in the limiting grooves 20 are connected with piezoelectric ceramic sheets 23. Through the piezoelectric ceramic sheets 23, the aluminum plate is shaken in the gap generated by the cutting, and current is generated based on the piezoelectric effect. The two piezoelectric ceramic sheets 23 cooperate with the longitudinal cutting knife 16 and are located between the gaps cut by the aluminum plate. A first spring 24 is arranged between the two shaking plates 22 and the limiting grooves 20.

The other ends of the two push rods 32 pass through the support block 27 and are connected to the push plate 33. There are three grinders 35. Through the three grinders 35, the driving coil 31 pushes the magnetic block 30 to move in the direction of the longitudinal cutter 16, thereby pushing the grinder 35 to move close to the longitudinal cutter 16, and grinding the longitudinal cutter 16 to restore the longitudinal cutter 16.

The spraying direction of the three nozzles 40 is toward the direction of the longitudinal cutting knife 16, and they cooperate with the three longitudinal cutting knives 16 respectively. Two electromagnetic heating plates 42 are connected between the two support plates 4. By passing the electromagnetic heating plates 42 Alternating current is input, and according to Faraday's law of electromagnetic induction, eddy current is generated inside the aluminum sheet passing between the electromagnetic heating plates 42. Due to the resistance of the aluminum sheet itself, the current is converted into heat energy, causing the aluminum sheet itself to heat up, and cooperate with the subsequent longitudinal cutting knife 16 to cut the aluminum sheet. The two electromagnetic heating plates 42 are respectively located on the side of the first guide roller 5 close to the longitudinal cutting knife 16 and the side of the first tension roller 6. The two electromagnetic heating plates 42 cooperate with each other, and a limit block 44 with an arc-shaped top is provided on the side of the receiving roller 43 close to the longitudinal cutting knife 16.

The support table 1 is connected to the output end of the two electric push rods 45. The top of the limit block 44 is connected to three partition plates 46, and the three partition plates 46 correspond to the three longitudinal cutting knives 16 respectively.

[0022] The working principle and use process of the present invention: When the present invention is in use, the staff places the aluminum plate on the first support seat 2, inserts one end of the aluminum plate between the first guide roller 5 and the first tension roller 6, passes through the two electromagnetic heating plates 42, passes through the longitudinal cutting knife 16 and the guide roller 17, passes through the second guide roller 7 and the second tension roller 8, passes through the top of the limit block 44, and is thus wound around the receiving roller 43 on the second support seat 41. During cutting, the receiving roller 43 rotates to drive the aluminum plate to be slowly released on the discharge roller 3. The staff can drive the fixed screws 13 to rotate and descend in the threaded barrel 12 by twisting the two fixed screws 13, thereby driving the fixed seat 11 at the bottom of the fixed screw 13 to descend, thereby driving the fixed The bearing seat 10 on the top of the fixed seat 11 descends, driving the first tension roller 6 and the second tension roller 8 between the bearing seats 10 to descend in the adjustment groove 9, the first tension roller 6 approaches the first guide roller 5, and the second tension roller 8 approaches the second guide roller 7, and the aluminum sheet placed on the first guide roller 5 and the second guide roller 7 is pressed, and the aluminum sheet is tensioned during transportation. The aluminum profiles of different thicknesses are pressed during transportation to facilitate the cutting operation with the longitudinal cutting knife 16. After the clamping and conveying of the first guide roller 5 and the first tension roller 6, the aluminum sheet enters between the two electromagnetic heating plates 42. In the process of the rotating shaft 15 driving the longitudinal cutting knife 16 to rotate and cut, the fixed sleeve 52 is driven to rotate, thereby driving the second permanent magnet 53 to rotate. When the second permanent magnet 53 rotates to the bottom of the cylinder 47, the bottom of the first permanent magnet 49 located in the cylinder 47 is the S pole, and the top of the second permanent magnet 53 is the S pole. According to the principle of like charges repel each other, the second permanent magnet 53 generates a thrust on the first permanent magnet 49, pushing the first permanent magnet 49 to rise in the cylinder 47. During the continuous rotation of the shaft 15, the thrust generated by the second permanent magnet 53 on the first permanent magnet 49 gradually decreases until the second permanent magnet 53 rotates to the bottom of the shaft 15, and the second permanent magnet 53 no longer generates a thrust on the first permanent magnet 49. At this time, due to gravity, the first permanent magnet 49 in the cylinder 47 drops down until the second permanent magnet 53 rotates to the top of the shaft 15 again. , and once again pushes the first permanent magnet 49 to continue to rise in the cylinder 47. During the continuous rotation of the rotating shaft 15, the first permanent magnet 49 continues to reciprocate and rise in the cylinder 47. According to Faraday's law of electromagnetic induction, when the first permanent magnet 49 moves up and down in the induction coil 51, it will cut the magnetic flux lines generated by the induction coil 51, thereby generating an induced current in the induction coil 51. After conversion, the generated alternating current is connected to the electromagnetic heating plate 42. The electromagnetic heating plate 42 is provided with a heating coil. By supplying power to the heating coil, the heating coil converts the connected alternating current into a high-frequency alternating current, thereby generating an alternating electromagnetic field. When this electromagnetic field meets the aluminum plate, according to Faraday's law of electromagnetic induction, eddy currents are rapidly generated inside the aluminum plate.Eddy currents continuously flow inside the aluminum sheet. Due to the existence of resistance, they are quickly converted into heat energy, thereby rapidly increasing the temperature of the aluminum sheet. Through the cooperation of the two electromagnetic heating plates 42, the aluminum sheet passing through is quickly and evenly heated, which is convenient for the subsequent longitudinal cutting knife 16 to reduce the brittleness of the aluminum sheet, make the cutting smoother, and reduce the deformation of the aluminum sheet during cutting. The heated aluminum sheet contacts the longitudinal cutting knife 16, and the longitudinal cutting knife 16 rotates to longitudinally cut the aluminum sheet. The notch 18 on the guide roller 17 cooperates with the longitudinal cutting knife 16, so that the aluminum profile can be completely cut. Through the cooperation of the three longitudinal cutting knives 16, the placed aluminum sheet is evenly divided.

[0023] The cut aluminum sheet passes through the bottom of the fixed plate 19. The piezoelectric ceramic sheet 23 arranged at the bottom of the fixed plate 19 is arranged in the gap generated by the aluminum sheet being cut by the longitudinal cutting knife 16. The cooperation of the first guide roller 5, the first tension roller 6, the second guide roller 7 and the second tension roller 8 enables the aluminum sheet to maintain a tensioned state before and after cutting. During cutting, long-term cutting will cause the longitudinal cutting knife 16 to wear, which will cause the gap generated by the aluminum sheet during cutting to become larger, resulting in material waste. In addition, due to the wear of the longitudinal cutting knife 16, the burrs on both sides of the cutting gap will increase. When the cutting gap of the aluminum sheet becomes larger, the piezoelectric ceramic sheet 23 is pushed due to the friction of the cutting gap of the aluminum sheet, thereby driving The shaking plate 22 on the top of the piezoelectric ceramic piece 23 moves in the limiting groove 20, and due to the cooperation of the first spring 24, the piezoelectric ceramic piece 23 shakes in the cutting gap of the aluminum plate. When the piezoelectric ceramic piece 23 is subjected to external force, the internal positive and negative charge centers are relatively displaced, thereby generating polarization, resulting in the appearance of bound charges of opposite signs on the surfaces of both ends of the material. This process realizes the conversion of mechanical effect to electrical effect, that is, positive piezoelectric effect. The power generation power of the piezoelectric ceramic piece 23 is related to the external stress and the frequency of change. Through the cooperation of the first spring 24, when the longitudinal cutting knife 16 is worn, the larger the gap of the aluminum plate cutting, the greater the amplitude of the shaking of the piezoelectric ceramic piece 23 in the gap, resulting in a greater current generated by the piezoelectric ceramic piece 23. The current generated by the piezoelectric ceramic piece 23 is discharged through the wire 25, converted through the converter 26, and powered to the driving coil 31 below. After the driving coil 31 is connected to the pulse current, the driving coil 31 generates a transient magnetic field. According to Ampere's law, the direction of the magnetic field of the driving coil 31 close to the magnetic block 30 is adjusted. By cooperating with the magnetic block 30, after the current is passed through the driving coil 31, the magnetic field generated generates a thrust on the magnetic block 30, and the push plate 33 is driven by the magnetic block 30 to move in the slide groove 28, and the second spring 34 is squeezed, so that the second spring 34 undergoes elastic deformation, driving the push rod 32 on the other side of the push plate 33 to move toward the longitudinal cutting knife 16, thereby driving the grinder 35 on one side to approach the longitudinal cutting knife 16, until Until it contacts the longitudinal cutting knife 16, during the process of the longitudinal cutting knife 16 rotating and cutting, the longitudinal cutting knife 16 is polished, so that the longitudinal cutting knife 16 does not need to stop running and can continue the cutting operation, avoiding the staff from disassembling and replacing the cutting knife in stages, affecting the work efficiency. After the grinding is completed, the longitudinal cutting knife 16 is restored to its state, and the cutting effect of the aluminum plate is restored, which causes the cutting gap to become smaller, and the piezoelectric ceramic piece 23 in the gap is squeezed, thereby causing the shaking range of the piezoelectric ceramic piece 23 to become smaller, resulting in a smaller current output by the piezoelectric ceramic piece 23, and a smaller current supplied to the drive coil 31, so that the magnetic field generated by the drive coil 31 is not enough to push the magnetic block 30. At this time, the reverse thrust generated by the second spring 34,The thrust of the magnetic field on the magnetic block 30 is greater than that generated by the driving coil 31. The push plate 33 located in the slide groove 28 will be pushed by the reverse thrust generated by the second spring 34 to perform a reset operation, thereby driving the grinder 35 on one side to leave the longitudinal cutter 16, so as to prevent the grinder 35 from continuously contacting the longitudinal cutter 16, thereby affecting the subsequent cutting of the longitudinal cutter 16. When the grinder 35 is used to grind the longitudinal cutter 16, the water pump 37 works to pump water in the water tank 36, discharges it through the connecting pipe 38, puts it into the delivery pipe 39, and passes through the nozzle 40 on one side of the delivery pipe 39. The longitudinal cutting blade 16 is sprayed to assist the grinding operation. The longitudinally cut aluminum sheet is wound on the receiving roller 43. The aluminum sheet is wound tighter on the receiving roller 43 through the support and limit of the limit block 44. The cut aluminum sheet is evenly wound on the receiving roller 43 through the partition plate 46 set on the top of the limit block 44, making the collection of aluminum sheets more convenient. During the continuous collection process, the diameter of the receiving roller 43 gradually increases and is shortened by the electric push rod 45, thereby driving the limit block 44 to descend, so that it can be better used with the receiving roller 43.
