Description

Technical Field

[0001] This invention relates to the field of cold rolling mill technology, specifically to a highly stable cold rolling mill. Background Technology

[0002] A cold rolling mill is a machine that rolls a sheet of material to a target thickness at a work hardening temperature (including room temperature). It can press metal materials into the required shape and size. It is mainly divided into different types of rolling mills, such as cold rolling mills for cold rolling steel bars and cold rolling mills for cold rolling sheet metal.

[0003] Currently, existing cold rolling mills used for cold rolling steel plates are prone to bending at both ends during processing. When the bent steel plate is rolled, the inner and outer layers of the steel plate are subjected to different stresses, namely tensile stress on the outer layer and compressive stress on the inner layer. This uneven stress distribution leads to instability in the steel plate during cold rolling. Therefore, we propose a highly stable cold rolling mill. Summary of the Invention

[0004] The purpose of this invention is to provide a highly stable cold rolling mill to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-stability cold rolling mill, comprising a machine body and a roll assembly mounted on the machine body, support frames are mounted on both sides of the machine body, and multiple conveying rollers are rotatably connected to each support frame. The multiple conveying rollers are used to convey steel plates.

There are two fixed tubes, one end of which is connected to two dust collection chambers respectively. The end of the fixed tube away from the dust collection chamber is connected to the connecting hose. The ends of the two connecting hoses close to each other are connected to the dust collection box. The input end of the vacuum pump is connected to the dust collection box. Through the provided dust collection component, the impurity particles on the surface of the steel plate are adsorbed.

[0015] The reset mechanism includes a fixed frame, a reciprocating component, and a roller leveling component. The fixed frame is located outside the support platform. The reciprocating component is installed on top of the fixed frame and is located directly above the support platform. There are two roller leveling components, and both roller leveling components are connected to the reciprocating component. Through the reset mechanism, the bent steel plate is leveled.

[0016] The reciprocating component includes a bidirectional threaded screw and a drive motor. The bidirectional threaded screw is rotatably connected to the top of the fixed frame, and the drive motor is fixedly installed on one side of the fixed frame. The drive motor is used to drive the bidirectional threaded screw. Through the reciprocating component, the two roller pressing and leveling components are driven.

[0017] The roller pressing and leveling component includes a connecting plate, a connecting block, a guide frame, and a leveling roller. The connecting plate is U-shaped and threaded onto the outside of a bidirectional threaded screw. The connecting plate is slidably connected to a fixed frame. The bottom of the connecting plate has two connecting ends. The connecting block has a connecting port inside, and the bottom of the connecting end slides through the connecting port. The connecting end has an inlet hole, and the inlet holes at the top of the two connecting ends are connected to each other by an inlet pipe. One end of the inlet pipe is connected to a telescopic pipe, and one end of the telescopic pipe is connected to a first blower. The first blower is fixedly installed on the support frame.

[0018] The guide frame is fixedly installed at the bottom of the two connecting blocks. The bottom of the guide frame is provided with a rotating opening, and the leveling roller is rotatably connected to the rotating opening.

[0019] The bottom of the connecting block is provided with an air outlet, and the guide frame is provided with an air guide groove that communicates with the air outlet. The bottom of the guide frame away from the leveling roller is provided with an oblique opening that communicates with the air guide groove. Through the provided roller pressing and leveling components, the bent steel plate is leveled.

[0020] Each of the four connecting blocks has a synchronization groove on one side close to each other. The four synchronization grooves are slidably connected to each other by a synchronization plate. The fixing frame has a synchronization port corresponding to two synchronization plates, and the synchronization plate slides through the synchronization port. A push block is fixedly connected to one end of the synchronization plate outside one of the synchronization ports. A push cylinder for pushing the push block is installed on the fixing frame. Through the provided synchronization plates, the four connecting blocks are synchronously driven.

[0021] The support platform is fixedly connected to an air inlet shell at its rear end, and a second blower is connected to the bottom end of the air inlet shell. The top of the air inlet shell is provided with an opening, and an air outlet slidably connected to the opening. A dust removal port is provided on the top of the air outlet hood and on the side near the moving steel plate.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figures 1 to 3 A high-stability cold rolling mill includes a machine body 1 and a roll assembly 2 mounted on the machine body 1. Support frames 3 are mounted on both sides of the machine body 1. Multiple conveying rollers 31 are rotatably connected to the support frames 3. The multiple conveying rollers 31 are used to convey steel plates. The support frames 3 are provided with a receiving area 32, and the receiving area 32 is located outside the steel plate entry end of the roll assembly 2. The multiple conveying rollers 31 are located on both sides of the receiving area 32.

[0041] The accommodating area is equipped with support platforms 4 at 32 locations, and the bottom of the support platforms 4 is equipped with multiple support legs 41 for supporting them.

[0042] The top of the support platform 4 is provided with a steel plate guide limiter 5, and the steel plate guide limiter 5 cooperates with multiple conveying rollers 31 to move the steel plate to the support platform 4.

[0043] Please see Figures 4 to 6 The steel plate guide limiting component 5 includes a moving screw 51, a moving block 52, a telescopic clamping component 53, and a dust suction component 54. The support platform 4 has moving slots 42 on both sides. There are two moving screws 51. The two moving screws 51 are rotatably connected to the two moving slots 42 respectively. The ends of the two moving screws 51 located on the outside of the support platform 4 are connected to each other by a synchronizing component 55. A driving component 56 is installed on one of the moving screws 51.

[0044] The movable block 52 is threaded onto the outside of the movable screw 51, and one end of the movable block 52 slides through the movable groove 42. The support frame 3 is provided with a movable opening at the position corresponding to the movable block 52. The telescopic clamping member 53 is installed on the movable block 52, and the two telescopic clamping members 53 cooperate with each other to clamp and fix the steel plate.

[0045] The vacuum cleaner 54 is connected between the two telescopic clamps 53.

[0046] The telescopic clamping component 53 includes an electric push rod 531, a connecting frame 532, and a clamping plate 533. The electric push rod 531 is fixedly installed on the moving block 52, and the output end of the electric push rod 531 is fixedly connected to the connecting frame 532. Both ends of the connecting frame 532 are fixedly connected to the clamping plate 533.

[0047] Each of the two clamping plates 533 has a suction port 5331 on one side that is close to each other, and the clamping plate 533 has a suction chamber 5332 that communicates with the suction port 5331 inside. One end of the suction component 54 is connected to the suction chamber 5332.

[0048] The vacuuming component 54 includes a fixed tube 541, a connecting hose 542, a dust collection box 543, and a vacuum pump 544. There are two fixed tubes 541, one end of which is connected to two vacuum chambers 5332 respectively. The end of the fixed tube 541 away from the vacuum chamber 5332 is connected to the connecting hose 542. The ends of the two connecting hoses 542 that are close to each other are connected to the dust collection box 543. The input end of the vacuum pump 544 is connected to the dust collection box 543.

[0049] Specific implementation process: When the bent steel plate is guided to the support platform 4 by multiple conveying rollers 31, the two moving screws 51 rotate synchronously under the operation of the synchronizing element 55 and the driving element 56. As the moving screws 51 rotate, they provide driving force to the moving blocks 52 on them. Due to the limiting effect of the moving blocks 52 by the moving groove 42, the two moving blocks 52 drive the clamping plates 533 to move along the steel plate until the two clamping plates 533 move to the steel plate. On both sides of the plate, two electric push rods 531 operate respectively, so that the two clamping plates 533 clamp and fix the steel plate to each other. Then, the steel plate is clamped to the support platform 4. Then, the vacuum pump 544 runs, so that the dust collection box 543 generates negative pressure. Then, through the two connecting hoses 542 and the two fixed pipes 541, the dust suction chamber 5332 and the dust suction port 5331 at the clamping plate 533 are formed with negative pressure, thereby achieving the adsorption of particulate impurities and debris on the surface of the steel plate.

[0050] Please see Figures 6 to 9 The support platform 4 is fixedly connected to the air inlet shell 9 at the tail end, and the bottom end of the air inlet shell 9 is connected to the second blower 91. The top of the air inlet shell 9 is provided with an opening 92, and an air outlet 93 is slidably connected to the opening 92. The top of the air outlet 93 and the side near the moving steel plate are provided with a dust removal port 931.

[0051] A movable rubber plug 94 is connected to the bottom of the air vent 93, and the movable rubber plug 94 is connected to the inside of the opening 92. The movable rubber plug 94 is provided with a transfer port 941, and the transfer port 941 keeps the air inlet shell 9 connected to the air vent 93. Multiple buffer springs 95 are fixed at equal distances at both ends of the top of the movable rubber plug 94, and the other end of each buffer spring 95 is fixedly connected to the top of the inside of the air inlet shell 9.

[0052] Specific implementation process: During the process of the bent steel plate being clamped above the support platform 4 by the two clamping plates 533, the second blower 91 is operated to output airflow through the dust removal port 931. The output airflow simultaneously scrapes off particulate impurities and debris on the lower surface of the bent steel plate. In addition, in this invention, the top of the exhaust hood 93 is set in a conical shape, so that as the steel plate moves relative to the exhaust hood 93, it simultaneously scrapes off particulate impurities and debris on the bottom of the steel plate. At the same time, since the movable rubber plug 94 at the bottom of the exhaust hood 93 is connected to the air inlet shell 9 through the buffer spring 95, the exhaust hood 93 can move and extend relative to the bent steel plate to cooperate with the scraping effect under the support of multiple buffer springs 95 during the movement of the bent steel plate.

[0053] Please see Figures 1 to 3 and Figures 10 to 12A reset mechanism 6 is provided above the steel plate guide limiter 5. The return mechanism is used to reset the bent steel plate so that the bent steel plate can be flattened and then enter the roll assembly 2 for rolling. The reset mechanism 6 includes a fixed frame 61, a reciprocating component 7 and a roll leveling component 8. The fixed frame 61 is located outside the support platform 4. The reciprocating component 7 is installed on the top of the fixed frame 61 and is located directly above the support platform 4. There are two roll leveling components 8, and both roll leveling components 8 are connected to the reciprocating component 7.

[0054] The reciprocating component 7 includes a bidirectional threaded screw 71 and a drive motor 72. The bidirectional threaded screw 71 is rotatably connected to the top of the fixed frame 61, and the drive motor 72 is fixedly installed on one side of the fixed frame 61. The drive motor 72 is used to drive the bidirectional threaded screw 71.

[0055] The roller leveling component 8 includes a connecting plate 81, a connecting block 82, a guide frame 83, and a leveling roller 84. The connecting plate 81 is U-shaped and threaded onto the outside of the bidirectional threaded screw 71. The connecting plate 81 is slidably connected to the fixed frame 61. The bottom of the connecting plate 81 has two connecting ends 811. The connecting block 82 has a connecting port 821 inside, and the bottom of the connecting end 811 slides through the connecting port 821, that is, the connecting end 811 slides through the connecting port 821. At the same time, the connecting end 811 and the connecting port 821 cooperate with each other. The connecting end 811 has an inlet hole 812, and the inlet holes 812 at the top of the two connecting ends 811 are connected to each other by an inlet pipe 85. One end of the inlet pipe 85 is connected to a telescopic pipe 86, and one end of the telescopic pipe 86 is connected to a first blower 87. The first blower 87 is fixedly installed on the support frame 3.

[0056] The guide frame 83 is fixedly installed at the bottom of the two connecting blocks 82. The bottom of the guide frame 83 is provided with a rotating opening, and the leveling roller 84 is rotatably connected to the rotating opening.

[0057] The bottom of the connecting block 82 is provided with an air outlet, and the guide frame 83 is provided with an air guide groove 831 that communicates with the air outlet. The bottom of the guide frame 83 on the side away from the leveling roller 84 is provided with an oblique opening 832 that communicates with the air guide groove 831.

[0058] Each of the four connecting blocks 82 has a synchronization groove 822 on one side that is close to each other. The four synchronization grooves 822 are slidably connected to each other by a synchronization plate 823. A synchronization port is provided on the fixing frame 61 at the position corresponding to two synchronization plates 823, and the synchronization plate 823 slides through the synchronization port. A push block 824 is fixedly connected to one end of the synchronization plate 823 located outside one of the synchronization ports. A push cylinder 825 for pushing the push block 824 is installed on the fixing frame 61.

[0059] The specific implementation process is as follows: When the bent steel plate is moved to the top of the support platform 4 by the two clamping plates 533, the cylinder 825 is pushed to run, thereby driving the four connecting blocks 82 to move down through the synchronous plate 823 until the two leveling rollers 84 at the bottom of the four connecting blocks 82 move down to the upper surface of the bent steel plate and contact the bent steel plate. Then, the motor 72 is driven to run, thereby causing the bidirectional threaded screw 71 to rotate. When the bidirectional threaded screw 71 rotates, it provides driving force in opposite directions to the two connecting plates 81. Due to the limiting effect of the fixed frame 61, the connecting plates 81 push the connecting blocks 82 to move along the edge of the bent steel plate through the two connecting ends 811 at their bottom. At the same time, the leveling rollers 84 roll against the upper surface of the bent steel plate. The two leveling rollers 84 move in directions that are both far apart and close to each other, thus performing reciprocating rolling and leveling on the bent steel plate. At the same time, the first blower 87 runs, which directs the airflow through the telescopic pipe 86, the inlet pipe 85, and the inlet hole 812 to the air outlet. The airflow then enters the air guide groove 831 through the two air outlets and is discharged through the inclined opening 832. Thus, the airflow blows the impurities and debris on the surface of the steel plate into the dust suction port 5331, thereby achieving thorough dust removal from the surface of the steel plate.

[0060] Example 2

[0061] Please see Figures 4 to 5 Example 2 is a further supplementary description of Example 1. Specifically, the synchronizing component 55 includes a synchronizing gear 551 and a gear chain 552. There are two synchronizing gears 551. The two synchronizing gears 551 are respectively fixedly installed on the synchronizing screw and located at one end outside the support platform 4. The gear chain 552 is connected to the outside of the two synchronizing gears 551.

[0062] The driving component 56 includes a first rotating gear 561, a second rotating gear 562, and a rotating motor 563. The first rotating gear 561 is fixedly sleeved on one end of one of the moving lead screws 51. The first rotating gear 561 is meshed with the second rotating gear 562. The second rotating gear 562 is located at the bottom of the support platform 4. The rotating motor 563 is fixedly installed at the bottom of the support platform 4 through a motor bracket, and the output end of the rotating motor 563 is fixedly connected to the second rotating gear 562.

[0063] By rotating the motor 563, the second rotating gear 562 drives the first rotating gear 561 to rotate. When the first rotating gear 561 rotates, it drives the inner ring of the moving lead screw 51 to rotate. Under the synchronous drive of the synchronous gear 551 and the gear chain 552, the two moving lead screws 51 rotate synchronously relative to the moving groove 42.
