Description

Technical Field

[0001] The utility model relates to the technical field of rolling equipment, and particularly relates to a guiding and feeding device for a cold rolling mill. Background Art

[0002] A cold rolling mill is an important industrial equipment for cold rolling metal materials at room temperature. Its working principle is based on the principle of plastic deformation of metals. By applying pressure to metal sheets or strips through rolls, plastic deformation occurs when they pass through the roll gap, thereby reducing the thickness of the material or changing its shape. Cold rolling mills are widely used in multiple industries such as steel, non-ferrous metals, automotive, construction, and metallurgy, and have become one of the indispensable equipments in these industries.

[0003] When steel is fed into a cold rolling mill, if there are insufficient guiding measures, the steel may shift, twist, or tilt due to gravity, inertia, or other external factors. This irregular initial state will directly affect the stability and consistency of the subsequent rolling process, and then have a chain reaction on the processing quality of the steel. For example, the shift of the steel may lead to uneven distribution of rolling pressure, causing increased roll wear or uneven thickness of the rolled product; while twisting or tilting may cause vibrations and noises during the rolling process, reducing the rolling efficiency and product accuracy. At the same time, the irregular state of the steel will also directly affect the quality control after processing. Since the deformation of the steel during the rolling process is continuous and cumulative, the initial small deviation may be amplified after multiple rollings, ultimately resulting in problems such as surface defects, dimensional deviations, or unqualified performance of the product. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0023] As Figures 1 to 4 shown, a guiding and feeding device for a cold rolling mill includes a support frame 1, a cold rolling mill main body 2, a conveying mechanism 3, and a guiding mechanism 4. The cold rolling mill main body 2 is fixedly connected to the support frame 1. The conveying mechanism 3 includes a conveyor belt 31, and the conveyor belt 31 is cooperatively connected to the support frame 1. Moreover, the cold rolling mill main body 2 is located at the output end of the conveyor belt 31. The guiding mechanism 4 includes a first guiding plate 41, a second guiding plate 42, and a third guiding plate 43. The sides of the first guiding plate 41 and the third guiding plate 43 are both parallel to the conveying direction of the conveyor belt 31. One end of the second guiding plate 42 is fixedly connected to the first guiding plate 41, and the other end of the second guiding plate 42 is fixedly connected to the third guiding plate 43. The third guiding plate 43 is located at the output end of the conveyor belt 31. There are two of the first guiding plate 41, the second guiding plate 42, and the third guiding plate 43, and they are oppositely arranged on both sides of the conveyor belt 31. The distance between adjacent first guiding plates 41 is greater than the distance between adjacent third guiding plates 43. The guiding mechanism 4 is slidably and cooperatively connected to the support frame 1.

[0024] Place the steel on the conveyor belt 31, and the conveyor belt 31 runs at a constant speed to convey the steel towards the cold rolling mill main body 2. When the steel enters the area of the guiding mechanism 4, it first encounters the first guiding plate 41. Since the first guiding plate 41 is parallel to the conveying direction of the conveyor belt 31 and its position is relatively fixed, it mainly plays a role in initially guiding and positioning the edge of the steel to ensure the basic centering of the steel in the horizontal direction.

[0025] Subsequently, the steel continues to move forward along the first guiding plate 41 and enters the area between the first guiding plate 41 and the third guiding plate 43 connected by the second guiding plate 42. And under the guidance of the second guiding plate 42, it enters the third guiding plate 43.

[0026] At the third guiding plate 43, the final guiding and positioning of the steel are completed. Since the distance between adjacent third guiding plates 43 is smaller than the distance between adjacent first guiding plates 41, this enhances the accuracy and stability of the guiding, ensuring that the position and orientation of the steel reach the best state before it reaches the cold rolling mill main body 2.

[0027] Through the guiding and positioning of the first guiding plate 41, the second guiding plate 42, and the third guiding plate 43, problems such as surface defects, dimensional deviations, and unqualified performance caused by the irregular initial state of the steel are effectively solved, significantly improving the quality and consistency of cold-rolled products.

[0028] The guiding mechanism 4 is slidably and cooperatively connected to the support frame 1, that is, the first guiding plate 41, the second guiding plate 42, and the third guiding plate 43 are all slidably and cooperatively connected to the support frame 1. By sliding the first guiding plate 41, the second guiding plate 42, and the third guiding plate 43 on the support frame 1, the distance between adjacent first guiding plate 41, second guiding plate 42, and third guiding plate 43 can be adjusted, so that the guiding mechanism 4 can adapt to steel of different widths or shapes, ensuring that the steel can always maintain a stable and regular state during the feeding process.

[0029] Reference Figure 2 As shown, in some specific implementation schemes, the guiding mechanism 4 further includes guiding slide rods 44 and guiding slide seats 45. There are two guiding slide rods 44 and two guiding slide seats 45. The two guiding slide rods 44 are respectively fixedly connected to the first guiding plate 41 and the third guiding plate 43, and the two guiding slide seats 45 are both fixedly connected to the support frame 1. The guiding slide rods 44 are slidably and cooperatively connected to the corresponding guiding slide seats 45. The second guiding plate 42 is provided with an adjusting component 46 for adjusting the distance between the adjacent first guiding plate 41 and the third guiding plate 43.

[0030] When it is necessary to adjust the distance between the adjacent first guiding plate 41 and the third guiding plate 43 to adapt to steel of different widths, the sliding cooperation of the guiding slide rod 44 in the guiding slide seat 45 ensures the smoothness of the adjustment process. This avoids possible jamming or sudden movement during the adjustment process, thus ensuring the accuracy and safety of the adjustment.

[0031] Reference Figure 4 As shown, in some specific implementation schemes, the adjusting component 46 includes an adjusting slide rod 47, a locking slide seat 48, and a locking rod 49. The adjusting slide rod 47 is fixedly connected to the second guiding plate 42, the locking slide seat 48 is fixedly connected to the support frame 1, the adjusting slide rod 47 and the locking slide seat 48 are slidably and cooperatively connected, the adjusting slide rod 47 is provided with a number of equally spaced adjustment through holes, the locking slide seat 48 is provided with a locking hole, and the locking rod 49 is disposed through the locking hole and the adjustment through holes.

[0032] When the adjusting slide rod 47 slides to the desired position, the operator reinserts the locking rod 49 into the corresponding adjustment through hole and the locking hole to lock the position of the second guiding plate 42. At this time, the distance between the first guiding plate 41, the second guiding plate 42, and the third guiding plate 43 is accurately adjusted and fixed.

[0033] Reference Figure 3As shown, in some specific embodiments, the guide mechanism 4 also includes a guide roller 410, and the top edges of the first guide plate 41, the second guide plate 42 and the third guide plate 43 are provided with a plurality of vertical rotating holes, and a plurality of guide rollers 410 are provided, and are rotatably connected with the corresponding rotating holes.

[0034] Guide rollers 410 contact the steel surface, converting sliding friction into rolling friction, significantly reducing the coefficient of friction and the resistance of the steel during the guiding process. Furthermore, by reducing direct contact between the steel and the guide plate, guide rollers 410 protect the guide plate and extend its service life. Furthermore, guide rollers 410 ensure that the steel maintains a stable trajectory during the guiding process, reducing deviation and shaking, thereby improving guiding accuracy.

[0035] In some specific embodiments, a cushioning pad is fixedly mounted on the outside of the guide roller 410. The cushioning pad is made of a highly wear-resistant, low-friction material, such as rubber or polyurethane. These materials have excellent lubricity and can significantly reduce the friction coefficient between the steel and the roller, thereby reducing wear and energy loss. When the steel passes through the guide mechanism 4, it may experience some impact due to differences in speed, size, or shape. The cushioning pad effectively absorbs this impact energy, preventing direct collision between the roller and the steel, and reducing noise and vibration.

[0036] refer to Figure 2 As shown, in some specific embodiments, the transport mechanism 3 further includes an active roller, a driven roller and a rotating motor 32. The active roller and the driven roller are respectively connected to the two ends of the support frame 1 in a rotating manner. The rotating motor 32 is fixedly connected to the support frame 1. The output end of the rotating motor 32 is coaxially fixedly connected to the active roller, and the conveyor belt 31 is wound between the active roller and the driven roller.

[0037] When the rotary motor 32 is powered on and started, its output drives the active roller to begin rotating. At this point, the friction between the conveyor belt 31 and the active roller causes the conveyor belt 31 to rotate with it. Simultaneously, the tension in the conveyor belt 31 causes the driven roller to also begin rotating. As the active roller continues to rotate, the conveyor belt 31 continues to move forward. Once placed on the conveyor belt 31, the steel is transported toward the cold rolling mill 2 as the conveyor belt 31 moves.

[0038] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be described in conjunction with specific application scenarios:

[0039] During actual use, place the steel to be processed at the starting end of the conveyor belt 31. At this time, the steel should be placed as much as possible at the center position of the conveyor belt 31 to facilitate subsequent guiding and positioning. Start the rotating motor 32, and the output end of the motor drives the driving roller to rotate. Due to the frictional force between the conveyor belt 31 and the driving roller, the conveyor belt 31 begins to move forward at a constant speed. At the same time, the driven roller begins to rotate under the tension of the conveyor belt 31 and jointly drives the conveyor belt 31 to move forward with the driving roller.

[0040] As the conveyor belt 31 moves, the steel is transported to the area of the guiding mechanism 4. First, the steel encounters the first guiding plate 41. The first guiding plate 41 is parallel to the conveying direction of the conveyor belt 31 and has a relatively fixed position. It plays a role in initially guiding and positioning the edge of the steel to ensure the basic centering of the steel in the transverse direction.

[0041] The steel continues to move forward and enters the area between the first guiding plate 41 and the third guiding plate 43 connected by the second guiding plate 42. In this area, the second guiding plate 42 further guides and positions the steel according to the preset spacing. Subsequently, the steel smoothly enters the area of the third guiding plate 43 under the guidance of the second guiding plate 42.

[0042] At the third guiding plate 43, the final guiding and positioning of the steel is completed. Since the spacing between adjacent third guiding plates 43 is smaller than the spacing between adjacent first guiding plates 41, this enhances the accuracy and stability of the guiding. At this time, the position and orientation of the steel reach the optimal state and are ready to enter the main body 2 of the cold rolling mill for processing.

[0043] When the steel is accurately guided and positioned at the entrance of the main body 2 of the cold rolling mill by the guiding mechanism 4, the cold rolling mill starts to work and cold-rolls the steel. During the processing, the guiding mechanism 4 maintains the stable state of the steel to ensure the processing accuracy and product quality.

[0044] During the entire processing process, the conveyor belt 31 continuously runs at a constant speed, continuously transporting new steel to the guiding mechanism 4 for guiding and positioning. At the same time, the processed steel is output from the other end of the main body 2 of the cold rolling mill, realizing continuous and efficient production operations.

[0045] When processing steel with different widths or shapes is required, the operator can adjust the spacing between the first guiding plate 41, the second guiding plate 42, and the third guiding plate 43 through the adjusting component 46. By sliding the adjusting slide bar 47 and locking the locking rod 49 at an appropriate position, it is convenient to adapt to the processing requirements of steel with different specifications.

[0046] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
