Description

Technical Field

[0001] This utility model belongs to the field of cold-rolled strip steel production technology, specifically, it relates to a straightening device for cold-rolled strip steel production. Background Technology

[0002] Cold-rolled strip steel is a thin sheet produced from hot-rolled strip steel and steel plate as raw materials through processes such as blank preparation, welding, pickling, cold rolling, annealing and finishing at room temperature. Due to its advantages such as relatively uniform thickness, high plasticity and wide range of mechanical properties, it is widely used in people's production and daily life.

[0003] Currently, during the production and forming process of cold-rolled strip steel, the high temperatures and stresses generated during welding can cause deformation between the steel plates, resulting in slight bending deformation that affects the flatness of the finished product and consequently its subsequent use. Therefore, straightening of cold-rolled strip steel is necessary. Traditional straightening methods rely on pressure rollers, which lack adjustable tension, leading to unsatisfactory results. Furthermore, the coiled strip itself has curvature and surface debris, which can easily affect the quality of the straightening rollers and the surface quality of the strip if directly fed into the straightening rollers. Therefore, further improvements to the straightening unit are required. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a straightening device for cold-rolled strip steel production, which avoids the previous cold-rolled strip steel straightening process by directly pressing with pressure rollers, which has poor effect and lacks residue cleaning, and avoids impurities causing scratches on the strip steel surface or affecting the quality of subsequent processing during the straightening process.

[0005] To solve the above-mentioned technical problems, this utility model discloses a straightening device for cold-rolled strip steel production, comprising:

[0006] The unwinding unit has an unwinding roller and an adjusting pressure roller located at the upper end of the unwinding roller. The adjusting pressure roller is installed at the output end of the drive motor via a shaft-connected handle, and displacement sensors are installed at both ends of the adjusting pressure roller to monitor the downward pressure in real time.

[0007] The straightening unit has a transition tension roll and a straightening roll group located behind the transition tension roll. The two ends of the transition tension roll are respectively equipped with extended brackets through bearings. The rear end of the extended bracket is sleeved with a fixed main shaft, which is installed in the straightening unit. The side of the sleeve of the extended bracket is welded with a swing bracket, which is driven by a drive cylinder to drive the transition tension roll to swing. The straightening roll group includes multiple straightening rolls arranged alternately. The height of the upper row of straightening rolls is independently adjusted by a servo electric cylinder. The two ends of the roll body are equipped with detachable wear-resistant end caps. The lower row of straightening rolls is fixedly installed and the roll surface is provided with a spiral wear-resistant texture.

[0008] The strip cleaning assembly is located between the unwinding unit and the straightening unit. The strip cleaning assembly includes brush rollers and dust-adhesive rollers arranged symmetrically on the top and bottom. The surface of the brush rollers is planted with wear-resistant nylon filaments, and the surface of the dust-adhesive rollers is covered with a replaceable adhesive layer.

[0009] According to one embodiment of the present invention, the straightening rollers are all driven by individual servo motors.

[0010] According to one embodiment of the present invention, the surface of the aforementioned transition tension roller is provided with anti-slip texture, and the texture is distributed in a diamond pattern.

[0011] According to one embodiment of the present invention, the brush roller and the dust-adhesive roller are provided with adjusting screws at both ends, and the contact pressure with the strip surface can be changed by rotating the adjusting screws.

[0012] According to one embodiment of the present invention, a receiving box is provided on the lower side of the brush roller and the dust-sticking roller.

[0013] Compared with the prior art, the present invention can achieve the following technical effects:

[0014] In the unwinding unit, the adjusting pressure roller is connected to the drive motor via a shaft-connected handle. With the help of displacement sensors at both ends to monitor the pressure in real time, the pressure on the strip on the unwinding roller can be precisely controlled to avoid the strip becoming loose or overly tight during unwinding, ensuring a stable and orderly unwinding process and reducing wrinkles or damage to the strip caused by unstable unwinding.

[0015] The transition tension rollers of the straightening unit swing through a swing bracket and a drive cylinder, which can flexibly adjust the angle according to the tension changes of the strip, ensuring that the strip maintains a suitable tension state before entering the straightening roller group. The upper row of straightening rollers can be independently adjusted in height by a servo electric cylinder, which can precisely adjust the amount of pressure for strips of different thicknesses and curvatures. Combined with the spiral wear-resistant texture of the lower row of straightening rollers, the straightening effect is significantly improved, and it can adapt to the straightening needs of various specifications of strips.

[0016] The strip cleaning assembly between the unwinding unit and the straightening unit works in tandem with symmetrically arranged brush rollers and adhesive rollers. The wear-resistant nylon filaments on the surface of the brush rollers effectively remove floating dust, debris, and other impurities from the strip surface, while the replaceable adhesive layer on the surface of the adhesive rollers further adsorbs residual fine dust. This dual cleaning action significantly improves the cleanliness of the strip surface, preventing impurities from scratching the strip surface or affecting the quality of subsequent processing during the straightening process.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

Detailed Implementation

[0022] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0023] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a cold-rolled strip steel production straightening device according to an embodiment of this utility model.

[0024] As shown in the figure, a straightening device for cold-rolled strip steel production includes: an uncoiling unit 10, a straightening unit 20, and an intermediate strip steel cleaning component 50, thereby completing the processes of uncoiling, cleaning, and straightening.

[0025] The unwinding unit 10 includes an unwinding roller 11 and an adjusting pressure roller 12 located at the upper end of the unwinding roller 11. The adjusting pressure roller 12 is mounted on the output end of the drive motor via a shaft-connected handle 13, and displacement sensors are installed at both ends of the adjusting pressure roller 12 to monitor the downward pressure in real time. In this embodiment, the unwinding roller 11 is used to mount cold-rolled strip steel coils. It is slowly unwound through the cooperation of a motor and a reducer. The adjusting pressure roller 12 at the upper end is driven to rotate by the motor, which drives the downward pressure to stop the strip steel coil. With the help of displacement sensors at both ends to monitor the downward pressure in real time, the pressure on the strip steel on the unwinding roller 11 can be precisely controlled, avoiding the strip steel from becoming loose or excessively tight during unwinding, ensuring a stable and orderly unwinding process, and reducing wrinkles or damage to the strip steel caused by unstable unwinding.

[0026] The straightening unit 20 has a transition tension roller 21 and a straightening roller group 22 located behind the transition tension roller 21. The two ends of the transition tension roller 21 are respectively equipped with extension brackets 30 through bearings. The rear end of the extension bracket 30 is sleeved with a fixed main shaft 31. The fixed main shaft 31 is installed in the straightening unit 20. The side of the sleeve of the extension bracket 30 is welded with a swing bracket 32. The swing bracket 32 ​​is driven by a drive cylinder 33, which drives the transition tension roller 21 to swing. The straightening roller group 22 includes multiple straightening rollers arranged alternately. The height of the upper row of straightening rollers is independently adjusted by a servo electric cylinder. The two ends of the roller body are provided with detachable wear-resistant end caps. The lower row of straightening rollers is fixedly installed. The roller surface is provided with a spiral wear-resistant texture. In this embodiment, the transition tension roller 21 swings through the swing bracket 32 ​​and the drive cylinder 33, which can flexibly adjust the angle according to the tension change of the strip steel, ensuring that the strip steel maintains a suitable tension state before entering the straightening roller group 22, which is practical and convenient. The upper row of straightening rollers can be independently adjusted in height through a servo electric cylinder, which can accurately adjust the amount of pressure for strip steel of different thicknesses and different degrees of curvature. Combined with the spiral wear-resistant texture of the lower row of straightening rollers, the straightening effect is significantly improved, and it can adapt to the straightening needs of various specifications of strip steel.

[0027] The strip cleaning assembly 50, located between the unwinding unit 10 and the straightening unit 20, includes a brush roller 51 and a dust-adhesive roller 52 symmetrically arranged vertically. The surface of the brush roller 51 is coated with wear-resistant nylon filaments, and the surface of the dust-adhesive roller 52 is covered with a replaceable adhesive layer. The brush roller 51 and dust-adhesive roller 52 work together to complete the cleaning, avoiding the inefficiency of manual cleaning. The wear-resistant nylon filaments on the surface of the brush roller 51 effectively remove floating dust, debris, and other impurities from the strip surface, while the replaceable adhesive layer on the surface of the dust-adhesive roller 52 further adsorbs residual fine dust. This dual cleaning action significantly improves the cleanliness of the strip surface, preventing impurities from scratching the strip surface or affecting subsequent processing quality during straightening. Alternatively, an air jet nozzle can be added for front-end blowing to improve efficiency, or negative pressure dust extraction can be used; this invention is not limited to these methods.

[0028] Preferably, the straightening rollers are all driven by individual servo motors, which can independently control the operating status of each roller, making it easy to flexibly adjust according to the straightening requirements of the strip and improve the straightening efficiency.

[0029] The transition tension roller 21 has anti-slip textures on its surface, and the textures are distributed in a diamond pattern, which increases the friction with the strip steel, prevents the strip steel from slipping, ensures stable transmission, and reduces production stoppages caused by slippage.

[0030] The brush roller 51 and the dust-adhesive roller 52 are equipped with adjusting screws at both ends. The contact pressure with the strip surface can be changed by rotating the adjusting screws, which can adapt to the cleaning needs of strips with different levels of dirt. This eliminates the need for frequent machine stops for adjustment and improves the overall production continuity.

[0031] A collection box 53 is provided under the brush roller 51 and the dust-adhesive roller 52 to collect impurities that fall off during the cleaning process and waste generated when replacing the adhesive layer, keeping the surrounding environment of the equipment clean and reducing the amount of cleaning work.

[0032] In summary, this utility model improves unwinding stability and straightening accuracy by precisely controlling the unwinding pressure through the straightening unit 20; the dual cleaning components improve the cleanliness of the strip steel; the wear-resistant design extends the equipment life; and the independent drive and convenient adjustment optimize operating efficiency and maintenance convenience.
