Description

Technical Field

[0001] This utility model relates to the field of strip processing line technology, and in particular to a novel stainless steel composite coil surface pre-polishing device. Background Technology

[0002] In China, composite steel coils are mostly rolled using a double-slab stacking method. Double-slab stacking involves symmetrically arranging the upper and lower composite steel billets, stainless steel to stainless steel, with a release agent in between. The stacked composite steel coils then enter a slitting and polishing line to process the finished product. The slitting and polishing line consists of two processes. The first process slits the upper and lower composite steel plates into two single-slab steel coils. The second process polishes the stainless steel surface of each single-slab steel coil, cleaning off the release agent to achieve a uniform gloss across the entire coil. To remove the release agent from the stainless steel surface, the production line is equipped with rough polishing and fine polishing machines, requiring both to be completed in one pass to obtain a qualified finished product. However, due to the thick layer and strong adhesion of the release agent, the polishing effect of the finished product is not ideal. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] A novel pre-polishing device for the surface of stainless steel composite coils, combined with Figure 1 , Figure 2 and Figure 3 As shown, the assembly includes: a frame 1, a lifting frame 2, a lifting drive mechanism, and a brush roller mechanism. The frame 1 is installed in a groove below the uncoiler of the single-slab steel coil. The lifting drive mechanism is installed on the frame 1 and drives the lifting frame 2 to rise and fall. The brush roller mechanism is installed on the lifting frame 2. The brush roller mechanism includes a brush roller 41 and a rotary drive component. The brush roller 41 is rotatably connected to the lifting frame 2. The lifting drive mechanism drives the lifting frame 2, thereby causing the brush roller 41 to press against the outer surface of the single-slab steel coil. The rotary drive component drives the brush roller 41 to rotate. The rotational linear speed of the brush roller 41 is set to 3-10 times the strip steel travel speed. The strip steel travel and the brush roller 41 rotation are independent actions. The lifting drive mechanism drives the brush roller 41 to press against the single-slab steel coil, and the rotary drive component controls the rotational linear speed of the brush roller 41 to be 3-10 times the strip steel travel speed, ensuring that the brush roller 41 slides relative to the strip steel, so that the brush roller 41 pre-polishes the release agent layer on the outer surface of the single-slab steel coil, thereby ensuring the polishing effect of the finished product.

[0024] Preferably, the clamping force of the brush roller 41 on a single billet steel coil is set to 0.5-2 tons. This device can ensure polishing ability by adjusting the clamping force and linear speed of the brush roller 41, and can remove 40%-60% of the release agent. This device has the characteristics of strong cleaning ability, easy replacement, convenient maintenance, and low cost.

[0025] Preferably, the lifting drive mechanism includes: a cylinder 31, two guide columns 32, two sets of guide sleeves 33, and a pneumatic valve assembly 34; the two sets of guide sleeves 33 are mounted on the frame 1, and the two guide columns 32 are respectively engaged with one set of guide sleeves 33. The ends of the guide columns 32 are fixedly connected to the lifting frame 2. The cylinder 31 is mounted on the frame 1 and located between the two guide columns 32. The output end of the cylinder 31 is connected to the lifting frame 2. The pneumatic valve assembly 34 connects the cylinder 31 and the air supply source. The cylinder 31 drives the lifting frame 2 to provide clamping force to the brush roller 41; the pneumatic valve assembly 34 regulates the air intake and exhaust to achieve power supply and power regulation; the two guide columns 32 and the two sets of guide sleeves 33 cooperate to guide the brush roller 41, and the two guide columns 32 move synchronously to ensure that the brush roller 41 can be tightly pressed onto the single billet steel coil in the length direction.

[0026] Preferably, the cylinder body of cylinder 31 is rotatably connected to the frame 1 via a cylinder support, and the output end of cylinder 31 is rotatably connected to the lifting frame 2 via a cylinder connector, so as to avoid jamming during the driving process of cylinder 31 due to installation errors or wear.

[0027] Preferably, the rotary drive component includes a motor 42 and a transmission assembly. The motor 42 is mounted on the lifting frame 2, and the motor 42 drives the brush roller 41 to rotate via the transmission assembly, thereby adjusting the rotational linear speed of the brush roller 41.

[0028] Preferably, the transmission assembly includes a drive sprocket 431, a chain 432, and a driven sprocket 433. The motor 42 drives the drive sprocket 431 to rotate, which in turn drives the chain 432 and the driven sprocket 433 to rotate. The driven sprocket 433 then drives the brush roller 41 to rotate. The cooperation of the drive sprocket 431, chain 432, and driven sprocket 433 increases the center distance, which helps to increase the distance between the motor 42 and the brush roller 41, thereby avoiding interference between the motor 42 and the strip steel. Furthermore, the chain drive can adapt to the harsh working conditions of polishing.

[0029] Preferably, it also includes an electronic controller 5, which receives instructions from the production line's control system to control the lifting drive mechanism and the rotary drive component.

[0030] Preferably, the frame 1 includes a connecting plate 11, a support frame 12, and a mounting plate 13. The connecting plate 11 is fixed to the side wall of the groove, the support frame 12 is mounted on the connecting plate 11, and the support frame 12 is connected to the mounting plate 13. The lifting drive mechanism is mounted on the side of the mounting plate 13 away from the support frame 12. The frame 1 ensures the installation and support of other components and guarantees the rigidity of the device. Furthermore, this device is small in size and can be installed below the uncoiler on the production line, allowing it to be added without altering other equipment on the production line.

[0031] Preferably, the upper surface of the lifting frame 2 is inclined upward along the conveying direction of the strip steel, which is conducive to the sliding off of polishing debris.

[0032] Preferably, the brush roller 41 is made of steel wire brush roller and is processed by double steel strip spiral winding process. The brush roller 41 has high hardness and long service life, and can strongly polish the surface of the strip steel and has strong surface cleaning ability.

[0033] The working principle of the device in this application is as follows:

[0034] After a single-slab steel coil is loaded onto the uncoiler drum, the production line's electrical control system sends a command to the controller 5, and the device enters the pre-polishing mode. At this time, the pneumatic valve group 34 opens, providing power to the cylinder 31. The cylinder 31 drives the lifting frame 2 to rise, with the guide columns 32 on both sides providing guidance. Until the brush roller 41 contacts the steel coil, the cylinder 31 continues to apply pressure, causing the brush roller 41 to press firmly onto the steel coil according to the set pressure value. After the steel coil is pressed, the uncoiler drum begins to rotate and open the coil. Simultaneously, the controller 5 controls the motor 42 and transmission components to drive the brush roller 41 to rotate. The linear speed of the brush roller 41 is maintained at 3-10 times the strip's travel speed, and the brush roller 41 pre-polishes the strip. This setting can be adjusted within this range according to the working conditions.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
