Description

Technical Field

[0001] The invention belongs to the technical field of aluminum plate processing, and specifically relates to an aluminum plate stamping and drawing pretreatment device and method. Background Art

[0002] Aluminum plate 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; When stamping and drawing the aluminum plate, in order to ensure that the aluminum plate can be processed smoothly and the processed aluminum plate can maintain its performance, the aluminum plate needs to be pre-treated; When pre-treating the aluminum plate, it is generally treated by blowing the aluminum plate. However, there are usually debris and oil stains left on the surface of the aluminum plate. When the gas is blown, the oil stains will spread on the aluminum plate, and the cleaning effect is not ideal. In addition, the oil stains and debris are mixed, which makes the aluminum plate's ability to absorb debris stronger, so that the debris cannot fall off the aluminum plate, thus affecting subsequent processing; And the aluminum plate cannot be preheated, resulting in low processing efficiency of the aluminum plate and the processing quality of the aluminum plate failing to meet the requirements; In addition, there is an existing aluminum plate stamping pretreatment equipment and method, which uses a conveyor belt to adhere to the surface of the aluminum plate to oil the aluminum plate. When the oiling operation is performed through the conveyor belt, the oil sprayed on the conveyor belt will stay at the position where the conveyor belt first contacts the aluminum plate. Therefore, during the continuous rotation of the conveyor belt, the oil on the belt continues to stay at the position that first contacts the aluminum plate, resulting in poor oiling effect for the aluminum plate that the conveyor belt contacts subsequently.

The air inlet 17 cooperates with the blowing heads 26. The blowing heads 26 are respectively located inside the "C"-shaped ventilation pipe 25, and the directions of the blowing heads 26 are inclined towards the cleaning tank 2, so that the surface treatment and cleaning effect of the aluminum plate is better, and it is more convenient for subsequent collection of the blowing. An air outlet 18 is provided on the top of the collecting hopper 14. A rotating shaft 15 is rotatably connected to the inner wall of the collecting hopper 14, and a plurality of driving blades 16 are connected to the surface of the rotating shaft 15; a heating resistance wire 28 and a heating box 30 are arranged between the first conveying component 12 and the second conveying component 13. By supplying power to the heating resistance wire 28, free electrons are introduced into the heating resistance wire 28 and collide with the atomic cores inside the heating resistance wire 28, transferring part of the kinetic energy to the atomic cores, resulting in an increase in the thermal vibration of the atomic cores, so that the temperature of the heating resistance wire 28 rises, thereby realizing the heating operation of the aluminum plate and assisting in the subsequent processing operation of the aluminum plate. The heating resistance wire 28 is connected to one side of the inner wall of the operation table 1, and the heating box 30 is located above the heating resistance wire 28; two oiling rollers 38 are connected to the top of the operation table 1, and the two oiling rollers 38 cooperate with each other; a blowing component 27 is arranged on one side of the operation table 1, and the blowing component 27 includes a cylinder body 271 and a magnetic block 275.

Springs 10 are arranged between the two fixed blocks 9 and the two fixed seats 11, and downward thrust is generated on the two fixed seats 11 through the two springs 10, so that the second sponge roller 7 is pushed to move downward in the adjusting groove 8 through the two fixed seats 11, so that after the aluminum plate is cleaned in the cleaning box 2, the first sponge roller 6 and the second sponge roller 7 are in closer contact with the aluminum plate, so that the wiping and cleaning effect of the aluminum plate is better. Figure 6 and Figure 7 One end of the rotating shaft 15 passes through the collecting bucket 14 and is connected to a rotating plate 19. One side of the rotating plate 19 is rotatably connected to a push rod 20. One side of the inner wall of the operating table 1 is connected to an insulating shell 21.

The gas blown out of the blowing head 26 is collected through the collecting bucket 14. By driving the driving blade 16 to rotate in the collecting bucket 14, the rotating plate 19 at one end is driven to rotate through the rotating shaft 15, thereby driving The push rod 20 pushes the permanent magnet 24 in the insulating housing 21, driving the permanent magnet 24 to move back and forth in the insulating housing 21. According to Faraday's law of electromagnetic induction, by cutting the magnetic field generated by the inductor 23, if the permanent magnet 24 moves in the magnetic field to cut the magnetic flux lines, the electrons in the permanent magnet 24 will be affected by the Lorentz force. The Lorentz force is a non-electrostatic force that can cause a potential difference, thereby generating a current to power the heating resistor 28. The other end of the push rod 20 is rotatably connected to one side of the permanent magnet 24, such as Figure 3 and Figure 4The cylinder 271 is connected to one side of the operating table 1, one end of the cylinder 271 is connected to an air inlet pipe 272, and the other end of the cylinder 271 is connected to an air outlet pipe 273.

By powering the driving coil 274, according to Ampere's law, the opposite sides of the two driving coils 274 are respectively N poles and S poles, thereby driving the magnetic block 275 to move in the cylinder 271, and then by changing the direction of the current, the direction of the magnetic field of the driving coils 274 on both sides is changed, thereby pushing the magnetic block 275 to move back and forth in the cylinder 271, and the magnetic block 275 pushes the gas in the cylinder 271 to be continuously discharged from the air outlet pipe 273, and the diameter of the air outlet pipe 273 is much smaller than the diameter of the cylinder 271, thereby increasing the pressure of the gas pushed out by the magnetic block 275, and the gas is blown out of the air blower 26 through the ventilation pipe 25 The water stains and debris remaining on the surface of the aluminum plate are cleaned up to achieve a better cleaning effect. A ventilation pipe 276 is connected to the top of the cylinder 271. The ventilation pipe 276 is located at a position of the cylinder 271 close to the air outlet pipe 273. A one-way valve 277 is provided on the ventilation pipe 276. When the magnetic block 275 moves back and forth, air is continuously supplied to the cylinder 271. The one-way valve 277 cooperates to prevent the magnetic block 275 from pushing the gas in. The gas is discharged from the ventilation pipe 276. The other end of the air outlet pipe 273 is connected to the ventilation pipe 25. Two heat insulation plates 29 are connected to the inner wall of the operating table 1.

[0019] Embodiment 2 Based on Example 1, Specifically, the inner wall of the operating table 1 is connected to a first oil tank 34 and a second oil tank 35, and the first oil tank 34 and the second oil tank 35 are connected. Figure 8 and Fig. 9 The bottom of the first oil tank 34 and the top of the second oil tank 35 are both provided with limiting grooves 36. The limiting grooves 36 cooperate with the oiling roller 38 to prevent the oil from flowing out of the limiting grooves 36. The oil can only be brought out through the oil adsorbed on the surface of the oiling roller 38 to apply the oil to the surface of the aluminum plate. The inner walls of the first oil tank 34 and the second oil tank 35 are rotatably connected with the first fixed shaft 37. The two oiling rollers 38 are respectively connected to the two first fixed shafts 37. The two oiling rollers 38 are respectively located in the two limiting grooves 36 and cooperate with the limiting grooves 36. The other ends of the two first fixed shafts 37 pass through the first oil tank 34 and the second oil tank 35 respectively and are located on one side of the inner wall of the operating table 1. Fig.11A support seat 39 is connected to the side of the operating table 1 away from the cleaning box 2. A second fixed shaft 40 is rotatably connected in the support seat 39. The two first fixed shafts 37 and the second fixed shaft 40 are both connected to limit wheels 41. Belts 42 are sleeved on the three limit wheels 41. Fig.12 and Fig.13 A storage cylinder 43 is connected to the side of the operating table 1 away from the cleaning box 2. The storage cylinder 43 is located on one side of the support seat 39. One end of the second fixed shaft 40 away from the limiting wheel 41 passes through the storage cylinder 43 and is rotatably connected to the inner wall of the storage cylinder 43. A plurality of driving blades 44 are connected to the surface of the second fixed shaft 40. The water vapor generated by the evaporation of water in the heating box 30 is discharged into the storage cylinder 43, and the driving blades 44 in the storage cylinder 43 are pushed, thereby driving the second fixed shaft 40 to rotate on the support seat 39. The belt 42 drives the two first fixed shafts 37 to rotate synchronously, thereby driving the two oiling rollers 38 to synchronously absorb oil in the first oil tank 34 and the second oil tank 35, and synchronously evenly apply oil to both sides of the aluminum plate. The application is more uniform and easy to operate. Multiple driving blades 44 are all located in the storage tube 43. The top of the storage tube 43 is connected to an air inlet 45, and the air inlet 45 is connected to the other end of the ventilation pipe 25. The bottom of the storage tube 43 is connected to an air outlet 46, and the air outlet 46 cooperates with the driving blades 44.

[0020] A stamping and drawing pretreatment method for an aluminum plate is applied to the above-mentioned embodiment 1 and embodiment 2, and the use method is as follows: When the present invention is in use, the staff puts the aluminum plate to be processed into the cleaning box 2 at the feed port 3, and the aluminum plate passes through the limiting roller 4 in the cleaning box 2. After passing through the limiting roller 4, the aluminum plate extends out at the discharge port 5, passes between the first sponge roller 6 and the second sponge roller 7 in the discharge port 5, passes through the first conveying component 12 for limiting conveyance, and then passes through the second conveying component 13 for limiting conveyance, so that the processed aluminum plate is passed out. When processing, the staff needs to add cleaning agent in the cleaning box 2. The height of the cleaning agent added is higher than the limiting roller 4 and lower than the feed port 3 and the discharge port 5 on both sides of the cleaning box 2. When the aluminum plate is pulled by the second conveying component 13, the aluminum plate is limited by the limiting roller 4, so that the aluminum plate entering the cleaning box 2 is fully contacted with the cleaning agent. The first sponge roller 6 and the second sponge roller 7 are in contact with each other to remove the oil and debris remaining on the surface of the aluminum plate. The cleaned aluminum plate passes through the first sponge roller 6 and the second sponge roller 7 for contact and adsorption. The cleaning agent on the aluminum plate is cleaned, and the debris remaining on the surface of the aluminum plate is wiped and cleaned. The fixed blocks 9 on both sides of the cleaning box 2 support the springs 10 at the bottom, so that the springs 10 on both sides generate a downward thrust, pushing the two fixed seats 11 to move downward, thereby driving the second sponge roller 7 to descend in the two adjustment grooves 8 and approach the first sponge roller 6, thereby clamping the aluminum plate passing through. The contact is closer and the cleaning effect on the surface of the aluminum plate is better. The cleaned aluminum plate passes through the ventilation pipe 25, and the two drive coils 274 are powered, and the directions of the two drive coils 274 are opposite. Similarly, according to Ampere's law, the side of the driving coil 274 located on the air inlet pipe 272 close to the air outlet pipe 273 is the N pole, the side of the driving coil 274 located on the air outlet pipe 273 close to the air inlet pipe 272 is the S pole, one end of the magnetic block 275 close to the air inlet pipe 272 is the N pole, and the other end is the S pole. According to the principle that like charges repel and opposite charges attract, the magnetic block 275 in the cylinder 271 is driven to slide toward the air outlet pipe 273, and the gas between the magnetic block 275 and the air outlet pipe 273 is pushed, so that the gas passes through the air outlet pipe 273 and enters the ventilation pipe 25. The diameter of the air outlet pipe 273 is much smaller than the diameter of the cylinder 271, so that when the gas in the cylinder 271 enters the air outlet pipe 273, the gas pressure increases, and the air blower provided on the ventilation pipe 25 The head 26 is used to blow out, thereby blowing and cleaning the water stains remaining on the surface of the aluminum plate, and processing the remaining debris, so that the cleaning effect is better. After the magnetic block 275 moves to the end of the cylinder 271 close to the outlet pipe 273, by changing the direction of the current supplied to the driving coil 274, the side of the driving coil 274 located on the inlet pipe 272 close to the outlet pipe 273 is the S pole, and the side of the driving coil 274 located on the outlet pipe 273 close to the inlet pipe 272 is the N pole, thereby pushing the magnetic block 275 to reset, so that the magnetic block 275 slides in the cylinder 271 close to the position of the inlet pipe 272. When it moves to the cylinder 271 close to the inlet pipe 272, the air enters the cylinder 271 at the ventilation pipe 276, which is convenient for pushing and using again.And through the setting of the one-way valve 277, the magnetic block 275 can push the gas into the outlet pipe 273 smoothly, and then by continuously changing the direction of the current, the magnetic block 275 in the cylinder 271 can move back and forth in the cylinder 271, and through the cooperation of the ventilation pipe 276, the gas entering the cylinder 271 through the ventilation pipe 276 can be continuously pushed out, so as to continuously clean the aluminum plate.

[0021] The gas blown out by the blowing head 26 first contacts the aluminum plate. After cleaning the aluminum plate, the gas adheres to the surface of the aluminum plate and flows toward the cleaning box 2. The gas on the top of the aluminum plate first contacts the collecting bucket 14, passes through the air inlet 17 of the collecting bucket 14, enters the collecting bucket 14, and pushes the driving blades 16 in the collecting bucket 14 to rotate. As the gas continues to enter the collecting bucket 14, the gas passes through the driving blades 16 and is discharged at the air outlet 18 at the top of the collecting bucket 14. The gas entering the collecting bucket 14 pushes the multiple driving blades 16 to rotate in coordination, thereby driving the rotating shaft 15 in the collecting bucket 14 to rotate. 14 rotates, driving the rotating plate 19 on one side to rotate, and the rotating plate 19 continues to rotate, driving the push rod 20 on one side to rotate, when one end of the push rod 20 installed on the rotating plate 19 moves to the side close to the insulating shell 21, the other end of the push rod 20 pushes the permanent magnet 24 located in the insulating shell 21 to move away from the rotating plate 19, and after the one end of the push rod 20 installed on the rotating plate 19 moves to the side away from the insulating shell 21, the other end of the push rod 20 pulls the permanent magnet 24 to move in the direction close to the rotating plate 19, and in the process of the rotating plate 19 continuing to rotate, the push rod 20 is continuously pushed. , pushes and pulls the permanent magnet 24 to move back and forth in the insulating housing 21, through the inductor 23 set inside the insulating housing 21, when the permanent magnet 24 moves in the inductor 23, the magnetic lines of force will cut the inductor 23, causing the magnetic flux to change. According to Faraday's law of electromagnetic induction, when the magnetic flux changes, an electromotive force will be generated in the inductor 23, and then a current will be generated. During the continuous movement of the permanent magnet 24, the generated current is stabilized. The generated current is adjusted by the converter and input into the heating resistor 28. When the current passes through the heating resistor 28, according to Ohm's law and Joule-Lenz law The resistance inside the heating resistor wire 28 will hinder the flow of current, thereby generating heat, thereby increasing the overall temperature of the heating resistor wire 28. The operation of heating the aluminum plate passing through the heating resistor wire 28 can reduce the hardness and strength of the aluminum plate by heating the aluminum plate, making it easier to deform, thereby improving the processing efficiency. In addition, by heating, the deformation resistance of the aluminum plate is reduced, and processing becomes easier, thereby improving the processing efficiency. Heating can also improve the plasticity and toughness of the aluminum plate. During the heating process, the grains in the aluminum plate are rearranged, and the residual stress at the grain boundary is eliminated, so that the plasticity and toughness of the aluminum plate are improved.

[0022] During the operation of the heating resistor 28, the heat is fully utilized through the cooperation of the heat insulation plate 29. The oil used for stamping and drawing of the aluminum plate is added into the first oil tank 34 and the second oil tank 35, and the oil is adsorbed by two oiling rollers 38. When the aluminum plate passes between the two oiling rollers 38, the aluminum plate is oiled. When the heating resistor 28 is heating, the heating box 30 on the top of the heating resistor 28 is simultaneously subjected to the heat emitted by the heating resistor 28, thereby heating the water in the heating box 30. The protrusion 31 provided at the bottom of the heating box 30 allows the heat to remain at the bottom of the heating box 30 for a longer time, thereby achieving a better heating effect on the water in the heating box 30. During the continuous heating process, the water in the heating box 30 boils, thereby generating water vapor. The steam enters the exhaust pipe 33 through the collector 32, enters the air inlet 45 at the top of the storage tube 43 through the exhaust pipe 33, enters the storage tube 43 through the air inlet 45, and pushes the driving fan blade 44 in the storage tube 43. The driving blades 44 are discharged at the outlet 46 at the bottom of the storage cylinder 43, and the steam continuously enters the storage cylinder 43, pushing the multiple driving blades 44 to rotate in coordination, thereby driving the second fixed shaft 40 to rotate in the storage cylinder 43, and the second fixed shaft 40 rotates on the support seat 39, and the two first fixed shafts 37 are driven synchronously by the belt 42, thereby driving the oiling rollers 38 in the first oil tank 34 and the second oil tank 35 to rotate. In the process of continuous rotation of the two oiling rollers 38, the oiling rollers 38 in the first oil tank 34 and the second oil tank 35 are driven to rotate synchronously. The surfaces of the oiling rollers 38 in the first oil tank 34 and the second oil tank 35 absorb the coating oil, and the oil placed in the first oil tank 34 and the second oil tank 35 is moved out by rotation. The limiting grooves 36 are used to limit the oil to prevent it from flowing out of the first oil tank 34. The oil absorbed on the surface of the oiling roller 38 contacts the aluminum plate through rotation, so that the surface of the aluminum plate is fully coated, reducing the friction during subsequent processing of the aluminum plate. After coating, the aluminum plate is moved out between the first oil tank 34 and the second oil tank 35 for subsequent processing operations.
