Description

Technical Field

[0001] The present invention relates to the technical field of cold-rolled thin plate processing, and particularly to a precise processing device and method for cold-rolled thin plates. Background Art

[0002] Cold-rolled thin plate coils refer to metal plates formed by further rolling hot-rolled coils at room temperature by a cold rolling mill. Due to their characteristics such as thin thickness, smooth surface, high dimensional accuracy, and excellent mechanical properties, they are widely used in industries such as automobiles, household appliances, construction, electronics, and packaging. Among them, since many products require cold-rolled thin plate coils of specific widths to meet downstream processing requirements, before the plates are used, a slitting machine is used to transversely shear them into multiple cold-rolled thin plate coils of the same size, and it is ensured that the cut surfaces of the cold-rolled thin plate coils are flat, without burrs, and without deformation.

[0003] Currently, there are the following disadvantages when shearing cold-rolled thin plate coils: 1. After transversely shearing the cold-rolled thin plate into multiple parts, only multiple isolation discs corresponding to the cut surfaces are used to separate the strips. However, if the cut surfaces of the strips are not completely cut, when the cold-rolled thin plate moves to the isolation discs, the isolation discs will not be able to effectively separate the strips, and the adhered strips will continue to move and get entangled at the isolation discs, resulting in abnormal subsequent processing; 2. The adhered strips will be squeezed when passing through the isolation discs, causing the strips to deform or the surface to be damaged, thereby affecting the quality of the subsequent processed products; 3. During shearing, the cutting roller and the subsequent separating roller are each independently stressed, and the loads of the cutting roller and the separating roller are uneven, which easily accelerates wear and shortens the service life of the equipment. At the same time, the independent stress on the cutting roller will result in uneven shearing force, causing uneven cut surfaces, increased burrs, or deformation of the plates, while the independent stress on the separating roller will cause the strips to shift during the separation process, resulting in inconsistent strip widths or irregular shapes.

[0004] Therefore, when the slitting machine shears cold-rolled thin plates, how to avoid incomplete cutting of the cold-rolled thin plates by the cutting mechanism and the independent stress on each cutting part, and achieve precise shearing of the cold-rolled thin plates, is a technical problem that needs to be solved by those skilled in the art.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1 and Figure 2 , a precision processing equipment for cold-rolled thin plates, including two bases 1 distributed left and right. On the upper end surfaces of the two bases 1, a first support component and a second support component are respectively arranged. A cutting component for rolling a cold-rolled thin plate into multiple strips is arranged on the first support component.

[0038] Please refer to Figure 2 , Figure 3 and Figure 4, a support frame 2 is provided at the right end of the first support assembly. A number of first separation assemblies 21 are provided inside the support frame 2. The first separation assembly 21 includes two separation rollers 211 rotatably provided at the front and back. The two separation rollers 211 roll towards each other and separate the cut cold-rolled thin sheet by frictional traction.

[0039] Please refer to Figure 2 , a second separation assembly 3 is provided on the second support assembly. When the cut cold-rolled thin sheet passes through the second separation assembly 3, it is in a V-shaped state, so that the cut cold-rolled thin sheet is secondarily separated.

[0040] Please refer to Figure 1 and Figure 2 , a third separation assembly 4 for separating adjacent cold-rolled thin sheet strips is provided at the right end of the second support assembly; the cut cold-rolled thin sheet strips pass through the first separation assembly 21, the second separation assembly 3 and the third separation assembly 4 in sequence to receive tertiary auxiliary separation, and finally the cold-rolled thin sheet is completely separated.

[0041] Please refer to Figure 1 and Figure 2 , an extrusion mechanism 5 is jointly provided on the first support assembly and the second support assembly; the extrusion mechanism 5 includes a triangular frame 51 that integrates the first support assembly and the second support assembly. A plurality of triangular frames 52 for simultaneously providing triangular structural support for the cutting assembly, the first separation assembly 21, the second separation assembly 3 and the third separation assembly 4 are provided inside the triangular frame 51.

[0042] Please refer to Figure 1 , Figure 2 and Figure 3 , the first support assembly includes a first support 11 and a second support 12 that are fixedly installed on the upper end surface of the left base 1 and distributed front and back. The support frame 2 is fixedly installed between the right end faces of the first support 11 and the second support 12 through a support frame; the second support assembly includes a first support 11 that is fixedly installed on the upper end surface of the right base 1 and is symmetric front and back.

[0043] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 , the cutting assembly includes a cutting roller 13 that is slidably installed up and down between the corresponding first support 11 and the second support 12. A number of cutting discs 131 are fixedly sleeved on the cutting roller 13 in a linear array from front to back; a driving roller is rotatably installed between the corresponding first support 11 and the second support 12 and is located directly below the cutting roller 13. A cutting plate 14 is fixedly installed between the corresponding first support 11 and the second support 12 and is located between the cutting roller 13 and the driving roller. Cutting grooves corresponding to the cutting discs 131 are formed through the upper end surface of the cutting plate 14. An extrusion disc corresponding to the cutting groove and in rolling contact with the cutting disc 131 is fixedly sleeved on the driving roller.

[0044] During specific operation, when the cold-rolled thin plate needs to be cut, the head of the thin plate is first passed between the cutting roller 13 and the cutting plate 14 so that the head of the thin plate is located between the extrusion disc and the corresponding cutting disc 131 .

[0045] Then, the external motor is started to rotate the driving roller, and the driving roller causes the cutting roller 13 to rotate synchronously through the external gear transmission mechanism, and the thin plate is sheared by cooperating with the extrusion disc and the corresponding cutting disc 131, so that the complete cold-rolled thin plate is rolled and cut into multiple strips of cold-rolled thin plates.

[0046] See also Figure 2 , Figure 3 and Figure 4 , the separation roller 211 is connected to the support frame 2 through a bearing, and the two separation rollers 211 in the same group are connected by a gear set, and the two separation rollers 211 in the same group are located on the right side of the corresponding cutting disc 131; the support frame 2 is provided with a driving unit 22 for providing power to the separation roller 211. The driving unit 22 includes a first motor 222 fixedly mounted on the support frame 2, a pulley 221 is fixedly sleeved on one of the separation rollers 211 in the primary separation assembly 21, and the output end of the first motor 222 is connected to a plurality of pulleys 221 through a belt transmission.

[0047] See also Figure 2 , Figure 3 , Figure 4 and Figure 6 A guide portion 23 for guiding the cold-rolled sheet separated by the primary separation component 21 is provided on the support frame 2. The guide portion 23 includes support vertical plates 231 fixedly installed at the front and rear ends of the support frame 2. A guide roller 233 and a guide roller 1 232 are installed between the support vertical plates 231 through bearings. The guide roller 1 232 and the guide roller 2 233 are both located at the lower right side of the gear group of the primary separation component 21.

[0048] During specific operation, the head of the thin plate is then passed under the separation roller 211, and passed over the guide roller 1 232, and then passed under the guide roller 233. Because the height of the guide roller 233 is lower than the gear set, this prevents the cold-rolled thin plate from contacting the gear set on the separation roller 211 during movement.

[0049] Subsequently, the first motor 222 is started to rotate one of the separating rollers 211 in the primary separation assembly 21 through a belt and pulley 221, and the corresponding two separating rollers 211 rotate slowly in opposite directions synchronously under the cooperation of a gear set. When the cold-rolled thin sheet passes through the primary separation assembly 21, the two separating rollers 211 will contact the cold-rolled thin sheet strip on the cutting plate 14, and thus pull the cold-rolled thin sheet strip formed by cutting through the frictional force of rolling in opposite directions. Due to the uniform distribution of the frictional force, the stress distribution on the thin sheet strip during cutting is more uniform, reducing the possibility of deformation and warping, ensuring the flatness of the product, and completing the primary auxiliary separation of adjacent cold-rolled thin sheet strips.

[0050] Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in FIGS.

[0051] During specific operation, subsequently, the head of the thin sheet is passed through above the left guiding roller 321, below the guiding roller 31, and above the right guiding roller 321 in sequence. The cold-rolled thin sheet after cutting here is in a V shape.

[0052] When the cold-rolled thin sheet continues to move to the right, under the cooperation of the front and rear guiding rollers 321 and the guiding roller 31, the cold-rolled thin sheet strip at this position is in a V shape, enabling the spacer disc 311 to separate the cut cold-rolled thin sheet. The V shape can increase the vertical distance between the cold-rolled thin sheet strips, thereby reducing the possibility of adhesion between the cold-rolled thin sheet strips, and thus completing the second separation of the cold-rolled thin sheet strips.

[0053] Please refer to Figure 2 、 Figure 3 and Figure 4 As shown in FIGS.

[0054] During actual operation, after the head of the thin plate passes above the second guiding roller 321 on the right side, it passes between the third guiding roller 414 and the support plate 411, and then an existing coiling machine is used to fix the head of the thin plate, and the coiling machine is started to coil the cut and formed cold-rolled thin plate strip.

[0055] During the movement of the cold-rolled thin plate strip, the third guiding roller 414 will squeeze the cold-rolled thin plate strip between the corresponding two guiding blocks 413, and the guiding blocks 413 will perform the third separation on the cut of the cold-rolled thin plate strip. Combining the above two separations, the three-stage auxiliary separation of the sheared cold-rolled thin plate is realized, gradually separating the strip, avoiding the adhesion problem caused by incomplete shearing, ensuring that the cut of the strip is flat and free of burrs, improving the appearance quality of the strip, and at the same time ensuring the consistency of the strip width and shape, meeting the requirements of high-precision processing.

[0056] Please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7 As shown in

[0057] Please refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in

[0058] It should be noted that after passing the head of the thin plate through the space between the third guiding roller 414 and the support plate 411, the triangular frame 51 is installed between the second support 12 and the corresponding first support 11, as well as between the symmetrically arranged front and rear first supports 11. Subsequently, the triangular frames 52 are respectively installed at the corresponding positions.

[0059] During the shearing process of the cold-rolled thin plate, the cutting discs 131, the first-level separation assembly 21, and the blanking discs 311 distributed along the same left-right straight line jointly correspond to one triangular frame 52. Two pressing blocks 541 provided on the triangular frame 52 apply support to the first pressing roller 531 and the second pressing roller 532, thereby providing unified support for the corresponding first-level separation assembly 21 and the blanking discs 311. The symmetrically arranged front and rear triangular support frames 543 support and limit both sides of the corresponding cutting disc 131. At the same time, the pressing block 542 applies support to the third guiding roller 414, and the support is used to keep the relative positions of the first-level separation assembly 21, the blanking discs 311, the cutting disc 131, and the pressing block 542 stable, preventing offset or deformation caused by the forces and vibrations generated during the shearing process.

[0060] The triangular frame 51 provides unified support for a number of triangular frames 52, and the triangular frames 52 provide triangular structural support for the three-level auxiliary separation structure and the cutting roller 13, effectively dispersing and bearing the forces and vibrations generated during the shearing process, improving the accuracy of shearing and separation, and enhancing the overall structural rigidity of the equipment.

[0061] Please refer to Figures 1 to 7 This invention also provides a processing method for the above-mentioned precision processing equipment for cold-rolled thin plates, which specifically includes the following steps:

[0062] S1. Preparation: Check whether the size, surface quality, and material of the cold-rolled thin plate meet the requirements.

[0063] S2. Loading: First, place the cold-rolled thin plate coil on the uncoiler and slowly unwind the coil. Pass the head of the thin plate through the space between the cutting roller 13 and the cutting plate 14, and then pass the head of the thin plate successively above the left second guiding roller 321, below the first guiding roller 31, and above the right second guiding roller 321. Then, place the head of the thin plate above the bearing plate 412 and pass it through the space between the third guiding roller 414 and the support plate 411, and adjust the position of the thin plate.

[0064] S3. Shearing: Pass the thin plate through the cutting assembly at a set speed, so that the cutting assembly shears the thin plate and divides it into strips of the required width.

[0065] S4. Separation: Start the first motor 222 to pull the cut cold-rolled plate through the friction force of the first-stage separation component 21 rolling towards each other, so that the cold-rolled plate strip is separated once. When the cold-rolled plate continues to move to the right, with the cooperation of the front and rear two guide rollers 2 321 and the guide roller 1 31, the cold-rolled plate strip at this location is in a V-shape, so that the separation disc 311 separates the cut cold-rolled plate for the second time; in the process of the cold-rolled plate strip moving, the guide block 413 will separate the incision of the cold-rolled plate strip for the third time, and the guide roller three 414 will squeeze the cold-rolled plate strip between the corresponding two guide blocks 413.

[0066] S5. Coiling: The coiler is then used to fix the head of the sheet, and the coiler is started to coil the cold-rolled sheet strip, and the strip is cut when the coil reaches the set length.

[0067] S6. Inspection: Check whether the width, cut quality and surface condition of the sheared strip meet the requirements, and clean up the waste and debris in the slitting machine and surrounding areas.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The execution part includes two first pressing blocks respectively located directly above the first pressing roller and the second pressing roller, a second pressing block located directly above the third guiding roller, and a triangular support frame symmetrically arranged before and after the corresponding cutting disc.

10. A precise processing method for cold-rolled thin plates, characterized in that: It is completed by using the cold-rolled thin plate precision processing equipment described in claim 1, specifically including the following steps: S1. Preparation: Check whether the size, surface quality, and material of the cold-rolled thin plate meet the requirements. S2. Loading: First, place the cold-rolled thin plate coil on the uncoiler and slowly unwind the coil. Then, pass the head of the thin plate through the cutting assembly, the first-level separation assembly, the second-level separation assembly, and the third-level separation assembly in sequence, and adjust the position of the thin plate. S3. Shearing: Pass the thin plate through the cutting assembly at a set speed, so that the cutting assembly shears the thin plate and divides it into strips of the required width. S4. Separation: Assist in separating the cut cold-rolled thin plate through the first-level separation assembly, the second-level separation assembly, and the third-level separation assembly in sequence. S5. Rewinding: First, let the cut strips enter the rewinder respectively. Then, wind the strips into coils by the rewinder, and cut the strips when the coil reaches the set length. S6. Inspection: Check whether the width, cut quality, and surface condition of the cut strips meet the requirements, and clean up waste materials and sundries.
