Description

[0002] Metal sheets, usually metal sheets with a thickness of less than 0.15 mm, are characterized by lightness, high strength, excellent electrical conductivity, thermal conductivity and corrosion resistance. These characteristics make metal sheets widely used in many fields such as electronics, automobiles, aerospace, etc. In the traditional metal sheet manufacturing process, the core process link is undoubtedly focused on rolling technology. As an efficient and widely used metal forming method, rolling applies continuous pressure to the metal blank through two or more rotating rollers to cause it to undergo plastic deformation, thereby obtaining metal sheets of the required thickness, width and length. In the cold rolling manufacturing process of metal sheets, hot-rolled steel coils are used as raw materials. After pickling to remove the oxide scale, cold continuous rolling is carried out. Affected by equipment accuracy, material defects and process control problems, metal sheets are prone to local depressions during the cold rolling process. The depression defects will cause local stress concentration of the material, thereby reducing its strength, toughness and fatigue resistance.

DETAILED DESCRIPTION

[0028] 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. Example

[0029] See also Figure 1-Figure 11 , the present invention provides a technical solution:

[0030] An intelligent metal sheet manufacturing device includes a cold rolling mill body 1 and a rolling roller 2, and also includes a leveling wheel 3. The leveling wheel 3 is located on the cold rolling mill body 1. There are multiple leveling wheels 3, and the two ends of the leveling wheel 3 have different thicknesses. The leveling wheel 3 is used to level the concave position on the metal sheet.

[0031] The flattening mechanism 4 is arranged on the cold rolling mill body 1, and the flattening wheel 3 is arranged on the flattening mechanism 4. The flattening mechanism 4 drives the flattening wheel 3 to press the metal sheet to flatten the concave position of the metal sheet.

[0032] The advantage of setting up the leveling mechanism 4 is that the leveling wheels 3 with different thicknesses at both ends push the materials on both sides of the metal sheet to fill the concave positions of the sheet, which can ensure uniform force and avoid material deformation or damage caused by excessive local force. On an automated production line, this leveling method can continuously process the metal sheet, greatly improving the leveling efficiency. At the same time, compared with traditional leveling methods, this design reduces the direct contact area between the metal sheet and the leveling tool, reducing the risk of scratches caused by friction.

[0033] The trigger component 8 is arranged on the leveling mechanism 4, and the trigger component 8 is used to drive the leveling wheel 3 at the corresponding position to work according to the concave position of the metal sheet.

[0034] The advantage of setting up the trigger component 8 is that it can accurately find the concave position on the metal sheet, ensuring that the leveling operation is only performed on the area that needs leveling, avoiding the problem of over-processing or insufficient processing that may be caused by indiscriminate leveling, thereby improving the leveling accuracy. At the same time, the process of automatic identification and leveling greatly reduces the need for manual intervention and improves the degree of automation of the production line. Since the leveling operation is faster and more accurate, it can shorten the production cycle, improve production efficiency, reduce dependence on manual operation, reduce labor costs, and reduce errors and mistakes caused by human factors.

[0035] The flattening mechanism 4 includes a flattening piece 5 arranged on the cold rolling mill body 1, and the flattening wheel 3 is driven by the flattening piece 5 to flatten the concave positions on the metal sheet. The flattening piece 5 is provided with a control piece 6, and the number of flattening wheels 3 that move in a single time is controlled by the control piece 6. The flattening piece 5 is provided with an assembly 7, and the assembly 7 is used to control the synchronous rotation of multiple flattening wheels 3.

[0036] The leveling part 5 includes a mounting frame 51 arranged on the cold rolling mill body 1, on which a load-bearing roller 52 is rotatably arranged, on which a fixed plate 53 is arranged, on which a plurality of sliding shafts 54 are slidably arranged, on which a mounting plate 55 is arranged, and the sliding shaft 54 ​​is provided with a mounting plate 55, and the mounting plate 55 is an L-shaped plate, on which a mounting shaft 56 is rotatably arranged, and the mounting shaft 56 is connected to the leveling wheel 3, and a driving motor 57 is arranged on the mounting shaft 56 at the outermost end of the plurality of mounting shafts 56.

[0037] The advantage of setting up the leveling piece 5 is that the leveling wheels 3 with different thicknesses at both ends push the materials on both sides of the metal sheet to fill the concave positions of the sheet, so that the concave positions can be leveled during the next rolling process. The design of the leveling wheels 3 with different thicknesses at both ends can avoid the generation of new depressions at the pushed positions while pushing the materials on both sides of the metal sheet to fill the concave positions of the sheet.

[0038] The control member 6 includes a top plate 61 arranged at one end of the sliding shaft 54 ​​away from the mounting plate 55, a return spring 62 is sleeved on the sliding shaft 54, two ends of the return spring 62 are respectively connected to the top plate 61 and the fixed plate 53, a slot 63 is opened on the top plate 61, and a pressing plate 64 used in conjunction with the slot 63 is provided on the top plate 61.

[0039] The advantage of setting the control member 6 is that the number of the leveling wheels 3 for squeezing the metal sheet can be adjusted according to the location of the depression on the metal sheet, thereby improving the leveling effect on the depression of the metal sheet.

[0040] The assembly 7 includes a docking groove 71 provided on the mounting shaft 56, a pneumatic chamber 72 is provided on the end of the mounting shaft 56 away from the docking groove 71, a piston plate 73 is slidably provided in the pneumatic chamber 72, a docking block 74 used in conjunction with the docking groove 71 is provided on the piston plate 73, and the docking block 74 is slidably connected to the pneumatic chamber 72, an expansion airbag 75 is provided on the leveling wheel 3, a push spring 76 is provided in the expansion airbag 75, and the expansion airbag 75 is communicated with the pneumatic chamber 72, an extrusion plate 77 is provided on the fixing plate 53, the end of the extrusion plate 77 is arc-shaped, a sliding groove 78 is provided on the extrusion plate 77, and the sliding groove 78 is movably connected to the mounting shaft 56, and a pressure sensor 79 is provided on the top plate 61.

[0041] The advantage of the assembly 7 is that it can push different numbers of leveling wheels 3 to rotate according to the recessed positions of the metal sheet, thereby improving the leveling effect of the metal sheet, while reducing the direct contact area between the metal sheet and the leveling wheel 3, reducing the risk of scratches caused by friction.

[0042] When the top plate 61 and the pressure sensor 79 are squeezed and descend, the sliding shaft 54 ​​is synchronously driven to overcome the elastic force of the reset spring 62 and descend, and the leveling wheel 3 is synchronously driven to descend. When the leveling wheel 3 descends, the expansion airbag 75 located thereon is driven to descend synchronously. When the expansion airbag 75 descends, it fits with the extrusion plate 77, so that the gas in the expansion airbag 75 is pushed into the pneumatic chamber 72. At this time, high pressure is formed in the pneumatic chamber 72, which pushes the piston plate 73 and the docking block 74 to move, thereby making the docking block 74 engage with the docking groove 71. When the pressure value of the pressure sensor 79 reaches the set value, the drive motor 57 is started, and the mounting shaft 56 and the leveling wheel 3 located on the mounting shaft 56 are synchronously driven to rotate to level the concave position on the metal sheet. The mounting shaft 56 rotates, and the docking block 74 is driven to rotate synchronously through the docking groove 71, thereby driving multiple synchronously descending leveling wheels 3 to rotate synchronously.

[0043] When the concave portion of the metal sheet is close to the side, the leveling wheel 3 located at the side descends. If the concave portion is close to the center of the metal sheet, multiple leveling wheels 3 will descend synchronously to improve the leveling effect on the metal sheet.

[0044] The trigger assembly 8 includes a sensing member 9 arranged on the mounting frame 51, and the sensing member 9 senses the recessed position on the metal sheet. The sensing member 9 is provided with a pushing member 10, and the pushing member 10 pushes the leveling wheel 3 corresponding to the recessed position on the metal sheet to descend and extrude the metal sheet. The pushing member 10 is provided with a driving member 11, and the driving member 11 increases the power for the pushing member 10 to work.

[0045] The sensing component 9 includes a receiving plate 91 arranged on the mounting frame 51, a positioning plate 92 is arranged on the mounting frame 51, a plurality of sliding rods 93 are slidably arranged on the positioning plate 92, a limiting plate 94 is arranged on the sliding rod 93, a sensing wheel 95 is arranged at one end of the sliding rod 93 away from the limiting plate 94, and a telescopic spring 96 is sleeved on the sliding rod 93 between the limiting plate 94 and the sensing wheel 95.

[0046] The advantage of setting up the induction element 9 is that it can accurately find the concave position on the metal sheet and automatically level it, ensuring that the leveling operation is only performed on the area that needs leveling, avoiding the problem of over-processing or insufficient processing that may be caused by indiscriminate leveling, thereby improving the leveling accuracy.

[0047] The pushing member 10 includes a plurality of storage tubes 101 arranged on the mounting frame 51, a pushing rod 102 is slidably arranged in the storage tube 101, the pushing rod 102 is located directly above the pressure sensor 79, a driving screw 103 is rotatably arranged on the mounting frame 51, the driving screw 103 passes through the pushing rod 102 and is threadedly connected to the pushing rod 102, and a driving gear 104 is arranged at one end of the driving screw 103 away from the pushing rod 102.

[0048] The driving member 11 includes a plurality of driving shafts 111 rotatably arranged on the mounting frame 51, a plurality of spring boxes 112 are arranged on the mounting frame 51, and the plurality of driving shafts 111 respectively penetrate the plurality of spring boxes 112 and are rotatably connected with the spring boxes 112, a spring spring 113 is arranged in the spring box 112, one end of the spring spring 113 is connected to the driving shaft 111, a winding wheel 114 is arranged on the driving shaft 111, a traction rope 115 is arranged on the winding wheel 114, and the traction rope 115 is connected to the limiting plate 94, a guide plate 116 is arranged on the mounting frame 51, and the traction rope 115 passes through the guide plate 116, and a driving gear 2 117 engaged with the driving gear 1 104 is arranged on the driving shaft 111.

[0049] When a depression appears during the continuous rolling process of the metal sheet, the induction wheel 95 will descend under the push of the telescopic spring 96 when it contacts the depressed position. The descent of the induction wheel 95 drives the sliding rod 93 and the limit plate 94 to descend synchronously. The descent of the limit plate 94 drives the traction rope 115 to move. The movement of the traction rope 115 drives the winding wheel 114 to rotate. The rotation of the winding wheel 114 drives the driving shaft 111 to rotate. The rotation of the driving shaft 111 drives the clockwork spring 113 to store force and synchronously drives the driving gear 2 117 to rotate.

[0050] The rotation of the driving gear 2 117 drives the driving gear 1 104 engaged with it to rotate, and the rotation of the driving gear 104 drives the driving screw 103 to rotate. The driving screw 103 rotates and drives the pushing rod 102 threadedly connected to it to move and extend out of the storage tube 101. The pushing rod 102 moves and squeezes the pressure sensor 79 and the top plate 61, pushing the pressure sensor 79 and the top plate 61 down. When the recessed position is in the middle of the metal sheet, the top plate 61 descends and drives multiple top plates 61 to descend synchronously through the pressing plate 64 and the slot 63, thereby driving multiple leveling wheels 3 to descend synchronously.

[0051] During use, when a depression appears during the continuous rolling of the metal sheet, the induction wheel 95 will descend under the push of the telescopic spring 96 when it contacts the depressed position. The descent of the induction wheel 95 drives the sliding rod 93 and the limit plate 94 to descend synchronously. The descent of the limit plate 94 drives the traction rope 115 to move. The movement of the traction rope 115 drives the winding wheel 114 to rotate. The rotation of the winding wheel 114 drives the driving shaft 111 to rotate. The rotation of the driving shaft 111 drives the clockwork spring 113 to store force, and synchronously drives the driving gear 2 117 to rotate.

[0052] The rotation of the driving gear 2 117 drives the driving gear 1 104 engaged with it to rotate, and the rotation of the driving gear 104 drives the driving screw 103 to rotate. The driving screw 103 rotates and drives the pushing rod 102 threadedly connected to it to move and extend out of the storage tube 101. The pushing rod 102 moves and squeezes the pressure sensor 79 and the top plate 61, pushing the pressure sensor 79 and the top plate 61 down. When the recessed position is in the middle of the metal sheet, the top plate 61 descends and drives multiple top plates 61 to descend synchronously through the pressing plate 64 and the slot 63, thereby driving multiple leveling wheels 3 to descend synchronously.

[0053] The top plate 61 and the pressure sensor 79 are squeezed and descend, synchronously driving the sliding shaft 54 ​​to overcome the elastic force of the return spring 62 and descend, and driving the leveling wheel 3 to descend synchronously. When the leveling wheel 3 descends, it drives the expansion airbag 75 located thereon to descend synchronously. When the expansion airbag 75 descends, it fits with the extrusion plate 77, so that the gas in the expansion airbag 75 is pushed into the pneumatic chamber 72. At this time, high pressure is formed in the pneumatic chamber 72, which pushes the piston plate 73 and the docking block 74 to move, thereby causing the docking block 74 to engage with the docking groove 71. At this time, the leveling wheel 3 is in a state of pressing the metal sheet but not rotating. At the same time, when the push rod 102 squeezes the pressure sensor 79 to make its pressure value reach the set value, the pressure sensor 79 starts the drive motor 57, and synchronously drives the mounting shaft 56 and the leveling wheel 3 located on the mounting shaft 56 to rotate, so as to level the concave position on the metal sheet. The mounting shaft 56 rotates, and drives the docking block 74 to rotate synchronously through the docking groove 71, thereby driving multiple leveling wheels 3 that descend synchronously to rotate synchronously. Example

[0055] Different from Example 1, the traction rope 115 is made of polyester fiber. The traction rope 115 made of polyester fiber has higher strength and better wear resistance, which can effectively improve the service life of the traction rope 115.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
