Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold rolling mill, in particular to an adjustable cold rolling mill for aluminum plate strip processing. BACKGROUND

[0002] The cold rolling mill is a mechanical equipment for rolling processing of metal plates, strips and pipes at room temperature, and belongs to the core category of metal plastic forming equipment. It is different from the hot rolling mill which needs to heat the blank. Its core function is to make the metal blank deform plastically through the extrusion force of the roller to obtain the finished product or semi-finished product meeting the requirements of size accuracy, surface quality and mechanical properties.

[0003] The prior art also has the following problems:

[0004] 1. The existing aluminum plate strip cold rolling mill does not set a special slip monitoring and linkage control structure, and only relies on the experience of the operator to judge and adjust the rolling parameters, so it cannot capture the slip precursors and real-time state of the mismatch between the aluminum plate moving speed and the roller rotating speed in real time. The rolling force adjustment response is lagging, it is difficult to quickly adapt to the working condition changes to eliminate the slip, which easily leads to scratches on the surface of the aluminum plate, uneven thickness, and even causes the belt to stop; at the same time, the aluminum plate clamping limiting structure has poor adaptability, and cannot dynamically adjust the clamping force according to aluminum plates of different thicknesses, which further aggravates the slip risk and seriously affects the rolling stability and the size accuracy and surface quality of the finished product;

[0005] 2. The existing cold rolling mill lacks a roller cleaning device that synchronously links with the rolling process. The aluminum scraps and impurity particles attached to the surface of the roller are difficult to remove in real time, which easily forms "roller marks" and transfers to the surface of the aluminum plate, causing surface defects such as scratches and pits. The emulsion and oil stains remaining on the surface of the aluminum plate after cold rolling lack efficient cleaning means, and the effect of the traditional cleaning method is limited. The residual emulsion will cause the interlayer adhesion of the coiled material, and the oil stains will affect the subsequent processing procedures, not only reducing the product qualification rate, but also requiring additional rework costs. At the same time, the residual impurities will reduce the friction between the roller and the aluminum plate, indirectly aggravating the slip problem.

[0006] Therefore, an adjustable cold rolling mill for aluminum plate strip processing is proposed. SUMMARY

[0049] The detection and calibration mechanism 300 includes a threaded rod 301 symmetrically slidably connected to the side wall of the processing table 101, a limiting groove 302 symmetrically opened on the outer wall of the top of the processing table 101, and an adjustment component 303 disposed on the outside of the threaded rod 301.

[0050] The protective mechanism 400 includes a second mounting plate 401 fixedly connected between the top ends of two mounting platforms 201, an L-shaped plate 402 symmetrically fixedly connected to the side wall of the second mounting plate 401, a cleaning assembly 403 disposed at the bottom of the second mounting plate 401, a shaft 404 symmetrically rotatably connected to the inner wall of the bottom end of the L-shaped plate 402, a protective assembly 405 symmetrically disposed on the outer side of the second mounting plate 401, and a nozzle 406 fixedly connected to the bottom end of the L-shaped plate 402.

[0051] During use: first, the operator connects the external emulsion conveying device to the spray pipe 406, so that the spray pipe 406 sprays emulsion on the position of the aluminum plate cold rolling, so that the emulsion flushes and cleans the rolling particles in the cold rolling process, and cools the high temperature generated in the cold rolling process; then the conveying device 102 transports the aluminum plate into the rolling assembly 203 arranged inside the rolling mechanism 200, so that the rolling assembly 203 cold-rolls the aluminum plate, and then the operator controls the electric telescopic rod 202 to adjust the cold-rolling gap of the rolling assembly 203 through the external controller, so that the electric telescopic rod 202 drives the detection and correction mechanism 300 to work through the rolling assembly 203, so that the rolling assembly 203 drives the threaded rod 301 to move towards the side close to the aluminum plate inside the machining table 101, so that the threaded rod 301 drives the adjusting assembly 303 to clamp and limit the side wall of the aluminum plate, detects the moving speed of the aluminum plate through the adjusting assembly 303, avoids the slipping when the moving speed of the aluminum plate is inconsistent with the cold rolling speed inside the rolling assembly 203, and inputs the detection result in the form of electrical signal into the control system inside the external controller, so that the control system sends an instruction to the external controller to adjust the cold-rolling gap of the rolling assembly 203, thereby realizing the effect of real-time monitoring and regulation of the slipping between the rolling assembly 203 and the aluminum plate; during the adjustment of the rolling assembly 203, the rolling assembly 203 drives the cleaning assembly 403 to work synchronously, so that the cleaning assembly 403 cleans the cold rolling device arranged inside the rolling assembly 203, ensures the cold rolling effect of the cold rolling device, and drives the protection assembly 405 through the cleaning assembly 403, so that the protection assembly 405 preliminarily cleans the impurities and oil stains on the upper surface of the aluminum plate, and also cleans the emulsion remaining on the outer surface of the cold-rolled strip, avoiding that the aluminum plate after cold rolling is usually rolled into a coil for storage, the residual emulsion forms a sticky film between the layers, and when the environmental temperature rises or the storage time is too long, the layers are easily adhered, affecting the quality of the aluminum plate strip.

[0052] Embodiment two

[0053] Refer to Figures 1 to 6 For the second embodiment of the application, which is different from the first embodiment: the rolling assembly 203 includes an annular plate 203a fixedly connected to the output ends of the two electric telescopic rods 202, a drive motor one 203c fixedly connected to the inner wall of the annular plate 203a, a cold rolling roller one 203b fixedly connected to the output end of the drive motor one 203c, a drive motor two 203d fixedly connected to the inner wall of the mounting table 201, and a cold rolling roller two 203e fixedly connected to the output end of the drive motor two 203d

[0054] Further, the annular plate 203a slides in the interior of the mounting table 201, ensuring the stability of the cold rolling roller one 203b during the vertical movement in the interior of the mounting table 201;

[0055] The driving end of the electric telescopic rod 202 slides at the top end of the mounting table 201, so that the driving end of the electric telescopic rod 202 drives the driving motor one 203c to move synchronously through the annular plate 203a, thereby adjusting the gap between the cold rolling roller one 203b and the cold rolling roller two 203e;

[0056] The driving motor one 203c, the driving motor two 203d and the electric telescopic rod 202 are electrically connected with the external controller, so that the external controller controls the driving motor one 203c and the driving motor two 203d to drive the corresponding cold rolling roller one 203b and cold rolling roller two 203e to rotate synchronously, so that the cold rolling roller one 203b and the cold rolling roller two 203e rotate towards the side where the cold rolling roller one 203b and the cold rolling roller two 203e are close to each other.

[0057] In use: first, the operator controls the electric telescopic rod 202 to start working through the external controller, so that the telescopic end of the electric telescopic rod 202 drives the annular plate 203a to move downward in the interior of the mounting table 201, so that the annular plate 203a drives the cold rolling roller one 203b and the driving motor one 203c to move synchronously downward, so that the cold rolling roller one 203b moves to a position that can meet the cold rolling requirements of the aluminum plate, then the conveying equipment 102 conveys the aluminum plate to the cold rolling roller one 203b and the cold rolling roller two 203e, so that the cold rolling roller one 203b and the cold rolling roller two 203e cold roll the aluminum plate synchronously, so that the cold rolling roller one 203b and the cold rolling roller two 203e roll and extrude the aluminum plate, so that the aluminum plate moves to the discharge side while being cold rolled, and the conveying equipment 102 conveys the cold rolled aluminum plate to the winding position for winding and storage.

[0058] Embodiment three

[0059] Reference Figures 1 to 6For the third embodiment of the present application, which is different from the first two embodiments, the adjusting assembly 303 comprises an adjusting plate 303a symmetrically rotatably connected to the outer wall of the annular plate 203a, a hinge block 303b rotatably connected to the bottom end of the adjusting plate 303a, a toothed plate 303c fixedly connected to the bottom end of the hinge block 303b, a limiting plate 303d fixedly connected to the side wall of the toothed plate 303c, a gear 303e symmetrically rotatably connected to the top end side wall of the machining table 101, a connecting plate three 303f fixedly connected to the top end of the threaded rod 301, a connecting rod one 303g symmetrically slidably connected to the inside of the connecting plate three 303f, a spring one 303h sleeved to the outer wall of the connecting rod one 303g, a groove plate 303i fixedly connected to the top end of the connecting rod one 303g away from the gear 303e, a plurality of detection rollers 303j linearly arranged rotatably connected to the inner wall of the groove plate 303i, and a rotational speed detector 303k fixedly connected to the top end of the groove plate 303i.

[0060] Further, the limiting plate 303d slides in the inside of the limiting groove 302, so that the limiting plate 303d can stably move under the limiting action of the limiting groove 302;

[0061] The threaded rod 301 is threadedly connected with the gear 303e, so that the gear 303e can drive the threaded rod 301 to move in the inside of the machining table 101 towards the side close to the aluminum plate during rotation;

[0062] The toothed plate 303c is engaged with the gear 303e, so that the toothed plate 303c can drive the gear 303e to rotate on the side wall of the machining table 101;

[0063] The two ends of the spring one 303h are fixedly connected to the outer walls of the connecting rod one 303g and the connecting plate three 303f respectively, so that the spring one 303h can adaptively adjust the size change of the aluminum plate during cold rolling, can ensure that the aluminum plate and the detection rollers 303j always abut against each other, and can make the aluminum plate drive the detection rollers 303j to synchronously rotate during movement;

[0064] The connecting rod one 303g slidably penetrates the inner wall of the connecting plate three 303f, and the outer wall of the detection roller 303j is provided with a rubber pad;

[0065] An electrical connection is established between the speed detector 303k and the external controller. A permanent magnet is installed inside the detection roller 303j, and a Hall element is installed inside the speed detector 303k. When the permanent magnet rotates with the detection roller 303j, the magnetic field strength sensed by the Hall element changes periodically, outputting high and low level pulse signals. The speed is calculated by the pulse frequency. Then, the speed detector 303k inputs the detection result into the control system inside the external controller in the form of an electrical signal. The control system analyzes the detection result with the speed of the cold rolling roll 203b, and then controls the electric telescopic rod 202 to start working through the external controller, so that the electric telescopic rod 202 adjusts the gap between the cold rolling roll 203b and the cold rolling roll 203e.

[0066] During use: As the electric telescopic rod 202 moves the first cold rolling roll 203b closer to the second cold rolling roll 203e, the annular plate 203a causes the top of the adjusting plate 303a to move downwards, causing the bottom of the adjusting plate 303a to move away from the annular plate 203a by contacting the hinge block 303b. This causes the hinge block 303b to move the toothed plate 303c synchronously, which in turn causes the limiting plate 303d to move synchronously within the limiting groove 302. Finally, the toothed plate 303c drives the gear 303e, which meshes with it, to rotate synchronously. This causes gear 303e to drive threaded rod 301 to move closer to the aluminum plate inside the processing table 101. The threaded rod 301, through connecting plate 303f, drives connecting rod 303g and spring 303h to move synchronously. Connecting rod 303g drives slotted plate 303i to move synchronously, causing slotted plate 303i to drive detection roller 303j and speed detector 303k to move closer to the aluminum plate until detection roller 303j contacts the side wall of the aluminum plate. The detection roller 303j, through slotted plate 303i, drives connecting rod 303g to move closer to the aluminum plate. The movement of one side of gear 303e causes connecting rod 303g to extend spring 303h, allowing detection roller 303j to clamp and limit the aluminum plate under the elastic action of spring 303h. Simultaneously, the movement of the aluminum plate drives detection roller 303j to rotate synchronously, enabling speed detector 303k to detect the speed of detection roller 303j and input the detection result as an electrical signal into the control system of an external controller. The control system then correlates the speed of detection roller 303j with the speed of cold rolling rolls 203b and 203e. By comparing and analyzing the rotational speeds, if the rotational speeds of cold rolling roll 203b and cold rolling roll 203e cannot match the rotational speed of the detection roller 303j, the external controller can control the electric telescopic rod 202 in real time. This allows the electric telescopic rod 202 to adjust the contact force between the cold rolling roll 203b and the aluminum plate, preventing the contact force between the cold rolling roll 203b and the aluminum plate from being too large or too small. This also prevents slippage between the cold rolling roll 203b and the aluminum plate, and prevents damage to the aluminum plate caused by the cold rolling roll 203b rotating in the same position for a long time.

[0067] When the rolling gap between cold rolling roll 203b and cold rolling roll 203e is adjusted by the electric telescopic rod 202, the annular plate 203a synchronously drives the adjusting plate 303a and the toothed plate 303c in the adjusting assembly 303 to move. Through the meshing transmission between the toothed plate and the gear 303e, the threaded rod 301 is moved, so that the detection roller 303j is pressed tightly against the side wall of the aluminum plate under the elastic action of the spring 303h. When the aluminum plate moves, it drives the detection roller 303j to rotate synchronously. The speed detector 303k collects the speed data in real time and transmits it to the external control. The speed of the controller is compared and analyzed with that of cold rolling roll 203b and cold rolling roll 203e. When there are signs of slippage due to speed mismatch or when slippage has already occurred, the external controller can immediately control the electric telescopic rod 202 to adjust the contact force between cold rolling roll 203b and the aluminum plate. This avoids slippage caused by excessive or insufficient rolling force, prevents the aluminum plate from being damaged by prolonged friction of the cold rolling rolls on the same position, significantly improves the stability of the rolling process and the surface quality and dimensional accuracy of the finished aluminum plate, and realizes real-time monitoring and dynamic control of slippage problems.

[0071] Furthermore, the other end of the torsion spring 403e, away from the baffle 403d, is fixedly connected to the side wall of the mounting platform 201. The fixing rod 403a is set at the top of the central axis of the cold rolling roll 203b. The bottom end of the scraper 403b is inclined towards the side closer to the cold rolling roll 203b, so that the scraper 403b can start to rotate during the downward movement of the cold rolling roll 203b, so that the scraper 403b can abut against the connecting plate 405e and rotate.

[0072] Furthermore, the dimensions of the connecting plate 405e and the slot 403c are matched, the other end of the torsion spring 405b away from the baffle 405a is fixedly connected to the inner wall of the L-shaped plate 402, and the dimensions of the abutting rod 405d and the adjusting groove 405j are matched, and the abutting rod 405d slides inside the adjusting groove 405j.

[0073] The elastic force of spring 405k in its naturally extended state is greater than the weight of the rubber scraper 405h, which allows the rubber scraper 405h to compress spring 405k through the slide bar 405g. This enables the rubber scraper 405h to come into contact with aluminum plates and strips of various thicknesses, ensuring the cleaning effect of the rubber scraper 405h.

[0074] Furthermore, the angle between the connecting plate 405e and the connecting plate 405c near the nozzle 406 is 160 degrees, and the nozzle 406 is used to connect to an external device for conveying emulsion.

[0075] During use: As the cold rolling roll 203b moves downward, it comes into contact with the bottom end of the scraper 403b. The scraper 403b rotates synchronously with the torsion spring 403e and the baffle 403d around the fixed rod 403a. Under the elastic action of the torsion spring 403e, the scraper 403b always comes into contact with the outer wall of the cold rolling roll 203b, thereby cleaning the impurity particles attached to the surface of the cold rolling roll 203b and ensuring the cold rolling effect of the cold rolling roll 203b.

[0076] During the flipping process of scraper 403b, scraper 403b drives slot 403c to rotate synchronously, causing slot 403c to abut against connecting plate 405e. Connecting plate 405e, through shaft 404, drives connecting plate 405c to flip downward, causing connecting plate 405c to move synchronously with contact rod 405d. Contact rod 405d slides inside adjusting groove 405j towards the side closer to shaft 404, and simultaneously abuts against adjusting block 405i, moving downward. Adjusting block 405i slides downward on the outer wall of the top of slide rod 405g, causing adjusting block 405i to compress spring 405k downward. The movement causes spring 405k to press down on slide bar 405g, which in turn moves downward inside mounting plate 405f. This causes slide bar 405g to drive two rubber scrapers 405h to contact the upper surfaces of the aluminum plate and aluminum strip respectively. During the movement of the aluminum plate and aluminum strip, the rubber scrapers 405h clean impurities and oil stains on the aluminum plate, preventing oil stains from affecting the friction between cold rolling roll 203b and the aluminum plate, thus ensuring the cold rolling effect of cold rolling roll 203b. At the same time, the rubber scrapers 405h clean the emulsion on the upper surface of the aluminum strip, ensuring the quality of the aluminum strip during winding and storage.

[0077] When the cold rolling roll 203b moves downward, it abuts against the scraper 403b in the cleaning assembly 403. Under the elastic action of the torsion spring 403e, the scraper 403b always sticks tightly to the outer wall of the cold rolling roll 203b, scraping off aluminum chips and impurity particles attached to the surface of the roll in real time, preventing impurities from forming roll marks and transferring to the surface of the aluminum plate, thus ensuring the rolling accuracy of the roll. When the scraper 403b flips, it drives the connecting plate 405e and the shaft 404 of the protective assembly 405 to rotate through the slot 403c. Then, through the abutment rod 405d and the adjusting block 405i, it drives the slide rod 405g and the rubber scraper 405h to move downward. Under the action of the spring 405k, the rubber scraper 405h sticks tightly to the surface of the aluminum plate and aluminum strip.

[0078] The rubber scraper 405h can clean oil and impurities from the surface of the aluminum sheet (preventing oil from affecting the friction between the roll and the aluminum sheet), and can also scrape off the residual emulsion on the surface of the aluminum strip after cold rolling, preventing interlayer adhesion when the coil is stored. At the same time, the emulsion sprayed by the nozzle 406 achieves cooling and preliminary cleaning, which greatly improves the surface quality of the finished aluminum strip, reduces subsequent rework processes, and ensures production continuity.
