Description

Technical Field

[0001] The invention relates to the field of cold-rolled steel plate production, and more specifically to a cold-rolled steel plate and a production device and a production method thereof. Background Art

[0002] Cold rolled steel refers to steel that has been processed by cold rolling at room temperature. Cold rolling is the process of processing hot rolled steel coils and then pressing them into the desired thickness through a series of rolling processes at room temperature. This method is opposite to hot rolling, which is carried out at high temperatures. The surface of cold rolled steel is smoother and has a high gloss, so its appearance is generally better than that of hot rolled steel. The cold rolling process can provide higher dimensional accuracy and smaller thickness tolerance, making cold rolled steel widely used in many precision manufacturing. The cold rolling process can increase the strength and hardness of steel, giving it superior mechanical properties in certain applications. However, the traditional production method of cold rolled steel cannot cold roll the steel plate through multiple sets of press rollers and driven rollers, the efficiency is average, and there are impurities on both sides of the cold rolled steel plate.

[0030] like Figure 11-12 As shown, this example can achieve the effect of preventing the driven roller 409 from deforming during cold rolling of the steel plate.

[0031] Since the cold-rolled steel plate production equipment includes a sliding frame 401, a driven roller 409 is rotatably connected to the upper part of the sliding frame 401, a flat shaft 410 is rotatably connected to the sliding frame 401, a support wheel 411 is welded to the middle part of the flat shaft 410, and the support wheel 411 is located at the lower side of the driven roller 409. The driven roller 409 is supported by the support wheel 411 to prevent the driven roller 409 from deforming when cold-rolling the steel plate, so that the driven roller 409 has a greater bearing capacity.

[0032] like Figure 11-12 As shown, this example can achieve the effect of cold rolling the steel plate.

[0033] Since vertical columns 403 are welded to the front and rear ends of the sliding frame 401, a lifting frame 404 is vertically slidably connected to the two vertical columns 403, and the lower end of the lifting frame 404 is rotatably connected to a pressure roller 408, and the pressure roller 408 is located above the driven roller 409. The lifting frame 404 is connected to a motor 407 by screws, and the output shaft of the motor 407 is connected to the rear of the pressure roller 408. The lifting frame 404 can slide vertically on the two vertical columns 403, thereby driving the pressure roller 408 to press against the driven roller 409, and the pressure roller 408 is driven to rotate by the motor 407, so that the steel plate passes between the pressure roller 408 and the driven roller 409, and then the steel plate is cold rolled.

[0034] like Figure 11-12 As shown, this example can achieve the effect of driving the lifting frame 404 to rise, fall and slide on the two vertical columns 403.

[0035] Since a top bar 405 is welded between the upper ends of the two vertical columns 403, a hydraulic cylinder 406 is connected to the middle of the top bar 405 by screws, and the movable end of the hydraulic cylinder 406 is connected to the upper side of the lifting frame 404 by screws, the lifting frame 404 is driven to rise and fall and slide on the two vertical columns 403 by the extension and retraction of the hydraulic cylinder 406.

[0036] like Figure 9-12 As shown, this example can achieve the effect of high-efficiency cold rolling of steel plates.

[0037] Since there are multiple sliding frames 401, rails 305 are welded at both ends of the base 301, and multiple sliding frames 401 are slidably connected to the two rails 305 on the base 301. Pads 402 are welded on the left and right sides of each sliding frame 401. Multiple sliding frames 401 can be installed through the two rails 305, so that multiple groups of pressure rollers 408 and driven rollers 409 are arranged on the left and right, so that the steel plate passes through the multiple groups of pressure rollers 408 and driven rollers 409, and then the steel plate is cold-rolled with high efficiency. Multiple pads 402 can be placed between multiple sliding frames 401 to prevent multiple groups of pressure rollers 408 and driven rollers 409 from getting too close.

[0038] like Figure 9-12 As shown, this example can achieve the effect of moving multiple sliding racks 401 to the right and close together.

[0039] Since two support columns 307 are welded to the right end of the base 301, and a stop rod 306 is welded to the upper ends of the two support columns 307, a socket is set on the left part of the base 301, and the L-shaped member 302 is inserted into the socket, and a stop pin 309 is inserted into the left part of the L-shaped member 302, and a strip frame 303 is fixed to the upper end of the L-shaped member 302, and two screws 304 are threadedly connected to the strip frame 303, and the two screws 304 are pressed on the sliding frame 401 on the left side, and the right sides of the multiple pads 402 are blocked by the stop rod 306, and the L-shaped member 302 can be easily removed from the socket. After the stop pin 309 is installed, the L-shaped member 302 can be fixed on the base 301, and then the strip frame 303 can be installed on the left part of the base 301, and then the two screws 304 are rotated to press the sliding frame 401 on the left side, so that the multiple sliding frames 401 move to the right and close together to prevent the multiple sliding frames 401 from loosening.

[0040] like Figure 5-10 As shown, this example can achieve the effect of facilitating the removal of the strip board 201 from the notch 102 .

[0041] Since a connector 308 is welded to the right end of the base 301, the connector 308 is connected to the left side of the container box 101 by screws, a notch 102 is provided at the rear of the container box 101, two bosses 103 are welded at the rear of the container box 101, and the strip board 201 is provided at the notch 102. Two threaded columns 205 are fixed to the rear side of the strip board 201, and the two threaded columns 205 are respectively inserted into the two bosses 103, and a nut is threadedly connected to the rear of each threaded column 205, which is inserted into the two bosses 103 by the two threaded columns 205, so that the strip board 201 can be easily removed from the notch 102.

[0042] like Figure 7-10 As shown, this example can achieve the effect of pickling the upper and lower sides of the steel plate at the same time.

[0043] Since a liquid inlet pipe 202 is welded in the middle of the base 301, a gate-shaped nozzle 210 is fixed at the front end of the liquid inlet pipe 202, and multiple spray holes 209 are arranged on the upper and lower sides of the inner side of the gate-shaped nozzle 210 from front to back, the steel plate after multiple cold rolling enters the gate-shaped nozzle 210, and the pickling liquid is connected through the liquid inlet pipe 202 on the gate-shaped nozzle 210, and then the pickling liquid is sprayed on the upper and lower sides of the steel plate from the multiple spray holes 209, and the upper and lower sides of the steel plate are pickled at the same time. The pickling liquid will fall into the container box 101 for collection.

[0044] like Figure 7-8 As shown, this example can achieve the effect of removing impurities on the surface of the steel plate.

[0045] Since connecting plates 206 are welded to the left and right ends of the front side of the strip plate 201, a lower scraper strip 208 is welded to the front end of each connecting plate 206, a square column 204 is welded to the upper side of the rear of the lower scraper strip 208, and the rear of the upper scraper strip 207 is vertically slidably connected to the square column 204, a round plate 203 is fixed to the upper end of the square column 204, and a compression spring is sleeved on the square column 204, and the compression spring is located between the round plate 203 and the upper scraper strip 207. The steel plate will also pass between two sets of upper scraper strips 207 and lower scraper strips 208. The compression spring applies downward pressure to the upper scraper strip 207, so that the upper scraper strip 207 presses against the lower scraper strip 208, and then the cold-rolled steel plate is scraped by the upper scraper strip 207 and the lower scraper strip 208 to remove impurities on the surface of the steel plate; and the upper scraper strip 207 and the lower scraper strip 208 located on both sides of the gate-shaped nozzle 210 can block the pickling liquid to prevent the pickling liquid from flowing along the steel plate to the outside of the container box 101.
