Abstract
Description
Technical Field
[0001] This invention relates to the field of cold rolling mill technology, specifically to a miniature stainless steel multifunctional cold rolling press. Background Technology
[0002] The stainless steel cold rolling press is a specialized cold rolling equipment designed for 201 or 304 austenitic stainless steel. It can cold-press stainless steel flat bars and scrap into various specifications of irregularly shaped wires, such as round, elliptical, rhomboid, rectangular, and plum blossom shapes, replacing the traditional oil drawing process. The equipment adopts grooved rolls and an independent drive structure, adapting to the roll gap adjustment requirements of the upper pressure roll's up-and-down movement. It integrates roll axial adjustment, mechanical pressing, and other mechanisms, adapting to the high work hardening characteristics of stainless steel. Forming is achieved through multi-pass rolling, with a compact structure, which can meet the continuous production needs of stainless steel wires of various shapes.
[0003] In existing stainless steel cold rolling mills, when pressing stainless steel using grooved rollers, the grooves are often compact cavities with numerous sharp corners and turns. Metal debris generated during rolling easily weds into the dead corners of the grooves, making it difficult to remove by gravity or natural friction. If these debris remain in the grooves for extended periods, they not only cause surface indentations and dimensional deviations in the finished wire, but also exacerbate wear on the roller grooves and can even lead to wire breakage due to localized stress concentration. Traditional maintenance methods require stopping the machine and manually reaching into the grooves for cleaning, reducing maintenance efficiency, increasing workload, and posing a safety hazard of roller mis-rotation.

[0019] The technical solutions in 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.
[0020] Please see the appendix Figure 1 -Appendix Figure 11This invention provides a miniature stainless steel multi-functional cold rolling press, including a frame 1. A position adjustment mechanism 2 is installed on the top of one side of the frame 1. A spraying mechanism 3 is installed inside one side of the frame 1. The position adjustment mechanism 2 drives the spraying mechanism 3 to move up and down. A curing mechanism 4 is installed inside the spraying mechanism 3. Two upper movable bearing seats 5 are slidably connected to the inside of the frame 1. An upper main shaft 6 is rotatably connected between the two upper movable bearing seats 5. Two lower bearing seats 7 are fixedly connected below the upper movable bearing seats 5 on the inside of the frame 1. A lower main shaft 8 is rotatably connected between the two lower bearing seats 7. Grooved pressure rollers 9 are fixedly connected to the outside of both the upper main shaft 6 and the lower main shaft 8. The curing mechanism 4 is used to clean debris stuck in the groove of the grooved pressure roller 9. A screw-down adjustment mechanism 10 is installed at the top of the archway 1, and the bottom of the screw-down adjustment mechanism 10 is installed on the top of the upper movable bearing seat 5. A centering adjustment mechanism 11 is installed on one side of the exterior of the archway 1. Mounting seats 12 are fixedly connected to the bottom of both sides of the archway 1. After the upper main shaft 6 and the lower main shaft 8 are driven to rotate by the main drive device, the two grooved pressure rollers 9 can be driven to rotate relative to each other. Then, the screw on the screw-down adjustment mechanism 10 is rotated downward, which drives the upper movable bearing seat 5 to move downward, and drives the upper main shaft 6 and the grooved pressure rollers 9 installed on the upper main shaft 6 to move downward. This can extrude and deform the steel strip, and the 6*2.2mm wide rectangular steel strip is pressed down to the long axis 5.76mm, the short axis 2.8mm, and the elliptical shape, with a deformation rate of 28%, and enters the second rolling. On the same principle, it is rolled down to the long axis 4.6mm and the short axis 3.3mm elliptical shape, with a deformation of 20%, and finally the third rolling. The major axis is 3.82 mm and the minor axis is 3.86 mm. They are basically close to 3.8 mm in diameter and are either perfectly round or have other floral patterns.
[0021] The position adjustment mechanism 2 includes a base mounting cylinder 201, which provides the installation position and space for liquid inflow. The base mounting cylinder 201 is externally fixedly connected to the top of one side of the archway 1. A piston 202 is slidably connected inside the base mounting cylinder 201, and the piston 202 can be pushed by liquid. A movable rod 203 is fixedly connected to the middle of the bottom end of the piston 202, serving a connecting function. Liquid inlet control valves 204 are fixedly connected to both the upper and lower ends of the base mounting cylinder 201, and the liquid inlet control valves 204 can control the opening and closing of the liquid flow path. A liquid inlet connecting pipe 205 is fixedly connected between the two liquid inlet control valves 204, serving to connect the two liquid inlet control valves 204. An inlet pipe 206 is fixedly connected to the middle of pipe 205. A water pump 207 is fixedly connected to the outside of archway 1. The water pump 207 can provide high-pressure liquid. The bottom of the inlet pipe 206 is fixedly connected to the output end of the water pump 207. A suction pipe 208 is fixedly connected to the input end of the water pump 207. The suction pipe 208 facilitates the water pump 207 to extract liquid. A storage tank 209 is slidably connected to the bottom of archway 1. The storage tank 209 can temporarily store liquid. The bottom end of the suction pipe 208 is detachably connected to the bottom of the storage tank 209. Drainage control valves 211 are fixedly connected to both the upper and lower ends of the base mounting cylinder 201. The opening or closing of the drainage control valves 211 can control whether the liquid flows out. A drainage connection is fixedly connected between the two drainage control valves 211. Pipe 212, the drain connecting pipe 212, serves to connect two drain control valves 211. A return pipe 213 is fixedly connected to the middle of the drain connecting pipe 212, which facilitates the drainage of liquid into the storage tank 209. The bottom of the return pipe 213 is detachably connected to the outside of the storage tank 209. The bottom of the movable rod 203 penetrates the bottom of the base mounting cylinder 201. A filter plate 210 is embedded in the top of the storage tank 209, which can filter the liquid cleaning the trough-shaped pressure roller 9. Starting the water pump 207 can draw the liquid out of the storage tank 209 through the liquid extraction pipe 208 and discharge it into the interior of the liquid inlet connecting pipe 205 through the liquid inlet pipe 206. The upper liquid inlet control valve 204 is opened and the lower liquid inlet control valve is closed. When valve 204 is closed, the lower drain control valve 211 is opened, and the upper drain control valve 211 is closed, allowing high-pressure liquid to be filled into the base mounting cylinder 201. This causes piston 202 and moving rod 203 to move downwards. When the upper inlet control valve 204 is closed and the lower inlet control valve 204 is opened, and the lower drain control valve 211 is closed and the upper drain control valve 211 is opened, high-pressure liquid is filled into the inlet connecting pipe 205, causing piston 202 and moving rod 203 to move upwards. To maintain the position of piston 202, both inlet control valve 204 and drain control valve 211 are closed. When one of the drain control valves 211 is opened...Liquid can enter the return pipe 213 through the drain connection pipe 212, and then flow back to the storage tank 209 through the return pipe 213. Furthermore, the up-and-down movement of the movable rod 203 can cause the mounting frame 303 to move up and down.
[0022] The sprinkler installation mechanism 3 includes two slide grooves 301, which are respectively opened at both ends of one side of the archway 1. Slide columns 302 are slidably connected inside the slide grooves 301, providing sliding space for the slide columns 302. An installation frame 303 is fixedly connected between the two slide columns 302, providing the installation position. The bottom of the movable rod 203 is fixedly connected to the outside of the installation frame 303. Rotating cylinders 304 are rotatably connected to both ends of the inner side of the installation frame 303, providing the installation position. A tension spring 305 is installed inside the rotating cylinder 304, and a movable limit plug 306 is slidably connected inside the rotating cylinder 304. A moving rod 307 is fixedly connected to the end of the movable limit plug 306 away from the tension spring 305. The two rotating cylinders... A liquid-passing pipe 308 is fixedly connected to the outside of the two rotating cylinders 304. The liquid-passing pipe 308 has the function of passing liquid and can evenly pass liquid into the interior of the two rotating cylinders 304. When no liquid enters the interior of the rotating cylinder 304, the tension spring 305 can pull the movable limit plug 306 and the moving rod 307 towards the liquid-passing pipe 308. The inner ends of the mounting frame 303 are fixedly connected to the fixing posts 309, which can provide the installation position. The outside of the fixing posts 309 is rotatably connected to the rotating sleeve 310. The outside of the rotating sleeve 310 is fixedly connected to the rotating mounting plate 311. The rotation of the rotating sleeve 310 can drive the rotating mounting plate 311 to rotate. The end of the moving rod 307 away from the tension spring 305 is rotatably connected to the rotating mounting plate 311. On the outside, a water distribution pipe 312 is fixedly connected between the two fixed posts 309. The water distribution pipe 312 provides a liquid passage space. Multiple nozzles 313 are fixedly connected to the outside of the water distribution pipe 312. The nozzles 313 can spray liquid. A connecting hose 315 is fixedly connected to the outside of the rotating cylinder 304. The connecting hose 315 can have a liquid passage function. The other ends of the two connecting hoses 315 are respectively fixedly connected to the two ends of the outside of the water distribution pipe 312. One end of the tension spring 305 is fixedly connected to the inside of the rotating cylinder 304. The other end of the tension spring 305 is fixedly connected to the end of the movable limit plug 306 away from the moving rod 307. A torsion spring 314 is provided inside the rotating sleeve 310. The torsion spring 314 is sleeved on the outside of the fixed post 309. One end of the torsion spring 314 is fixedly connected to the outside of the rotating cylinder 304. The other end of the torsion spring 314 is fixedly connected to the outside of the fixed column 309 and the inside of the rotating sleeve 310. When the liquid inlet control valve 204 is closed, the liquid is introduced into the liquid inlet pipe 308 through the curing mechanism 4. The liquid pushes the movable limit plug 306 towards the rotating mounting plate 311, thereby driving the moving rod 307 to extend out of the rotating cylinder 304. This, in turn, drives the rotating mounting plate 311 towards the grooved pressure roller 9, thus driving the curing mechanism 4 towards the grooved pressure roller 9. At the same time, as the liquid continuously enters, it enters the water distribution pipe 312 through the connecting hose 315 and is sprayed out through the nozzle 313. After the chip removal is completed, the automatic valve 415 is closed.The liquid will no longer enter the interior of the rotating cylinder 304. At this point, under the action of the tension spring 305, the movable limit plug 306 moves away from the rotating mounting plate 311, thereby pulling the moving rod 307 back into the rotating cylinder 304. This, in turn, moves the rotating mounting plate 311 away from the grooved pressure roller 9. Simultaneously, the torsion spring 314 uses its reaction force to rotate the rotating sleeve 310 downwards, which in turn assists the tension spring 305 in pulling the rotating mounting plate 311 away from the grooved pressure roller 9. This allows the curing mechanism 4 to move away from the surface of the grooved pressure roller 9.
[0023] The maintenance mechanism 4 includes a roller brush 401. The rolling of the roller brush 401, in conjunction with the liquid sprayed from the water distribution pipe 312, cleans the debris trapped in the groove of the trough-shaped pressure roller 9. Both ends of the roller brush 401 have mounting grooves 402 inside, providing mounting positions. A spring 403 is installed inside the mounting groove 402, and a limiting plate 404 is slidably connected inside the mounting groove 402, serving a limiting function. A movable column 405 is fixedly connected to the end of the limiting plate 404 away from the mounting groove 402. Multiple slots 406 are provided on the outside of the movable column 405, one of which rotates the mounting plate 311. An externally fixed mounting box 409 provides an installation position. An impeller 410 is rotatably connected inside the mounting box 409, rotating when the liquid flows. A slot 411 is provided in the middle of the impeller 410, allowing the movable column 405 to be inserted. Multiple locking blocks 412 are fixedly connected to both the inner wall of the slot 411 and the inner side of the bearing of another rotating mounting plate 311. When the locking slots 406 and the locking blocks 412 engage, the movable column 405 rotates when the impeller 410 rotates, thereby driving the roller brush 401 to move through the limiting plate 404. As the device rotates, the slot 406 engages with the block 412. Both movable posts 405 are inserted into the bearings of the two rotating mounting plates 311, with one post 405 inserted inside the slot 411. A connecting hose 413 is fixedly connected to the outside of the mounting box 409, allowing liquid from the mounting box 409 to flow into the liquid inlet pipe 308. The other end of the connecting hose 413 is fixedly connected to the middle of the liquid inlet pipe 308. A connecting pipe 414 is fixedly connected to the bottom of the mounting box 409. An automatic valve 415 is fixedly connected to the outside of the liquid inlet pipe 206. After the automatic valve 415 is opened... The liquid in the inlet pipe 206 can be introduced into the interior of the mounting box 409 through the connecting pipe 414. The other end of the connecting pipe 414 is fixedly connected to the outside of the automatic valve 415. The roller brush 401 has a through groove 407 at one end near the mounting box 409. A lever 408 is fixedly connected to the outside of one of the limiting plates 404. The through groove 407 can provide space for the lever 408 to slide. The lever 408 is slidably connected inside the through groove 407. One end of the spring 403 is fixedly connected to the interior of the mounting groove 402. The other end of the spring 403 is fixedly connected to the end of the limiting plate 404 away from the movable column 405. When liquid enters the connecting pipe 414, the high-pressure liquid drives the impeller 410 to rotate. This allows the impeller to engage with the locking block 412 inside the slot 411 and the locking groove 406 on one of the movable columns 405, causing the movable column 405 to rotate. This, in turn, drives the limiting plate 404 and the roller brush 401 to rotate. As the roller brush 401 rotates, its bristles clean the debris trapped in the groove of the grooved pressure roller 9. To disassemble the roller brush 401, simply press the movable column 405, the end furthest from the mounting box 409, towards the center of the roller brush 401, causing it to leave the bearing inside the rotating mounting plate 311. Simultaneously, pull the lever 408, the end closest to the mounting box 409, towards the center of the roller brush 401. This moves the limiting plate 404 towards the center of the roller brush 401, and utilizes the limiting plate 404... 4. Compression spring 403, which in turn allows the movable column 405 to leave the interior of slot 411, at which point the roller brush 401 can be removed. When installing a new roller brush 401, first press the movable columns 405 at both ends of the roller brush 401 toward the middle, so that the movable columns 405 retract into the interior of the mounting groove 402. When one end of the movable column 405 is aligned with the middle of the bearing of the rotating mounting plate 311 and the other end is aligned with the slot 411, the reaction force of the spring 403 pushes the limiting plate 404 and the movable column 405 to move away from the middle of the roller brush 401 and insert them into the bearing of the rotating mounting plate 311 and the interior of the slot 411. If the slot 406 and the block 412 are not aligned, simply rotate the roller brush 401, which will drive the limiting plate 404 and the movable column 405 to rotate, thereby aligning the slot 406 and the block 412.
[0024] Working principle: The main drive device drives the upper spindle 6 and lower spindle 8 to rotate, which in turn drives the two grooved pressure rollers 9 to rotate relative to each other. Then, the screw on the adjusting mechanism 10 is pressed down and rotated downward, causing the upper movable bearing seat 5 to move downward, and driving the upper spindle 6 and the grooved pressure rollers 9 mounted on the upper spindle 6 to move downward, thereby extruding and deforming the steel strip. The water pump 207 is started, which can draw out the liquid in the storage tank 209 through the liquid extraction pipe 208 and discharge it into the liquid inlet connecting pipe 205 through the liquid inlet pipe 206. The upper liquid inlet control valve 204 is opened and the lower liquid inlet control valve 204 is closed. At the same time, the lower liquid discharge control valve 211 is opened and the upper liquid discharge control valve 211 is closed, which allows the high-pressure liquid to be filled into the base mounting cylinder 201, thereby driving the movable bearing seat 5 to rotate downward. When the piston 202 and the movable rod 203 move downwards, the upper liquid inlet control valve 204 is closed and the lower liquid inlet control valve 204 is opened. After the lower liquid outlet control valve 211 is closed and the upper liquid outlet control valve 211 is opened, high-pressure liquid is filled into the liquid inlet connecting pipe 205, which can drive the piston 202 and the movable rod 203 to move upwards. After maintaining the position of the piston 202, both the liquid inlet control valve 204 and the liquid outlet control valve 211 are closed to maintain the position of the piston 202. When one of the liquid outlet control valves 211 is opened, the liquid can enter the interior of the return pipe 213 through the liquid outlet connecting pipe 212 and flow back to the interior of the liquid storage tank 209 through the return pipe 213. The up and down movement of the movable rod 203 can drive the mounting frame 303 to move up and down. After the inlet control valve 204 is closed, the automatic valve 415 is opened, and the liquid enters the connecting pipe 414, then through the mounting box 409 into the connecting hose 413. The connecting hose 413 then guides the liquid into the liquid inlet pipe 308. The liquid pushes the movable limit plug 306 towards the rotating mounting plate 311, thereby causing the moving rod 307 to extend out of the rotating cylinder 304. This, in turn, causes the rotating mounting plate 311 to move towards the grooved pressure roller 9, thus moving the maintenance mechanism 4 towards the grooved pressure roller 9. Simultaneously, as the liquid continuously enters, it also flows through the connecting hose 315 into the water distribution pipe 312, causing... Liquid is sprayed out through nozzle 313. After the chip removal is completed, the automatic valve 415 is closed, so the liquid will no longer enter the interior of the rotating cylinder 304. At this time, under the action of tension spring 305, the movable limit plug 306 is driven to move away from the rotating mounting plate 311, which in turn can pull the moving rod 307 back into the interior of the rotating cylinder 304, and then drive the rotating mounting plate 311 to move away from the grooved pressure roller 9. At the same time, the torsion spring 314 will also use its own reaction force to drive the rotating sleeve 310 to rotate downward, which can also assist the tension spring 305 in pulling the rotating mounting plate 311 away from the grooved pressure roller 9. At this time, the curing mechanism 4 can be driven away from the surface of the grooved pressure roller 9. When liquid enters the connecting pipe 414, the high-pressure liquid drives the impeller 410 to rotate. This allows the impeller to engage with the locking block 412 inside the slot 411 and the locking groove 406 on one of the movable columns 405, causing the movable column 405 to rotate. This, in turn, drives the limiting plate 404 and the roller brush 401 to rotate. As the roller brush 401 rotates, its bristles clean the debris trapped in the groove of the grooved pressure roller 9. To disassemble the roller brush 401, simply press the movable column 405, the end furthest from the mounting box 409, towards the center of the roller brush 401, causing it to leave the bearing inside the rotating mounting plate 311. Simultaneously, pull the lever 408, the end closest to the mounting box 409, towards the center of the roller brush 401. This moves the limiting plate 404 towards the center of the roller brush 401, and utilizes the limiting plate 404... 4. Compression spring 403, which in turn allows the movable column 405 to leave the interior of slot 411, at which point the roller brush 401 can be removed. When installing a new roller brush 401, first press the movable columns 405 at both ends of the roller brush 401 toward the middle, so that the movable columns 405 retract into the interior of the mounting groove 402. When one end of the movable column 405 is aligned with the middle of the bearing of the rotating mounting plate 311 and the other end is aligned with the slot 411, the reaction force of the spring 403 pushes the limiting plate 404 and the movable column 405 to move away from the middle of the roller brush 401 and insert them into the bearing of the rotating mounting plate 311 and the interior of the slot 411. If the slot 406 and the block 412 are not aligned, simply rotate the roller brush 401, which will drive the limiting plate 404 and the movable column 405 to rotate, thereby aligning the slot 406 and the block 412.
