Description

Technical Field

[0001] The invention relates to the technical field of metal strip processing equipment, in particular to a slitting device for metal strip production. Background Art

[0002] In the metal processing industry, metal strip slitting machine is a commonly used equipment used to cut wide metal strips into strips of required width. With the continuous improvement of industrial production requirements for metal material quality, metal strip slitting machines are facing increasingly higher challenges in cutting accuracy and surface treatment quality.

[0003] A battery pole piece cutting mechanism disclosed in Chinese Patent Publication No. CN113953577A includes one or more disc cutting blades, and the cutting of the metal strip is achieved by rotating the cutting blades.

[0004] However, compared with the existing technologies in the related fields, during the cutting process, burrs are often generated on the edge of the metal strip due to the interaction between the cutting blade and the metal strip. These burrs not only affect the appearance quality of the metal strip, but may also affect subsequent processing processes such as welding and assembly. In addition, the edge finish of the metal strip after cutting is not ideal and cannot meet the high standards of surface treatment. Therefore, an additional deburring step is required, which affects the overall production efficiency and increases the production cost. In addition, burrs or fragments of some materials are easy to adhere to the cutting blade, and the cutting quality will be reduced due to chip accumulation. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background technology, and provide a slitting device for metal strip production.

[0008] Furthermore, the adjustment assembly includes an annular member slidably arranged on the outer surface of the fixed column, and a support block is fixedly arranged on the outer surface of the annular member.

[0009] Furthermore, the guide assembly comprises a connecting block fixedly mounted on the supporting block, a fixing ring is fixedly arranged at one end of the connecting block away from the supporting block, and a wave groove is arranged on one side of the fixing ring close to the filing member.

[0010] Furthermore, a guide column is fixedly provided on one side of the filing member close to the wave groove, and the cooperation between the wave groove and the guide column enables two adjacent filing members to slide back and forth in an alternating manner.

[0016] The beneficial effects of the present invention are as follows: by arranging filing members, adjustment components and guide components, when the rotating shaft drives multiple shearing rotary disc cutters to rotate, the cooperation between the wave groove and the guide column is utilized to make two adjacent filing members slide back and forth alternately, and then the filing members rub the edge of the metal strip, and the edge of the metal strip is finely filed, thereby not only effectively removing burrs, but also significantly improving the smoothness of the edge of the metal strip.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Additional aspects and advantages of the present invention will be further given in the following description in conjunction with the accompanying drawings, and in part will become apparent from the following description, or may be learned through practice of the present invention.

[0022] An embodiment of a slitting device for producing a metal strip according to the present invention is as follows: Figures 1 to 9 As shown, the shearing machine tool 1 includes a shearing machine tool 1, a rotating shaft 2 is provided inside the shearing machine tool 1, a driving member 12 is provided at one end of the rotating shaft 2, and the driving member 12 is used to control the rotating shaft 2 to rotate. A plurality of shearing rotating disc knives 3 are provided on the outer surface of the rotating shaft 2, and the metal strip is sheared by the plurality of shearing rotating disc knives 3. The plurality of shearing rotating disc knives 3 rotate synchronously with the rotating shaft 2. Both sides of the plurality of shearing rotating disc knives 3 are provided with mounting grooves 301, and a plurality of filing members 4 are slidably provided inside the two mounting grooves 301. The shearing machine tool 1 is fixed at the rear side of the rotating shaft 2. A fixed column 5 is fixedly installed, and an adjustment component 6 is slidably provided on the outer surface of the fixed column 5 corresponding to the position of multiple shearing rotating disc cutters 3. The adjustment component 6 is provided with a guide component 7 for controlling the reciprocating sliding of multiple filing parts 4 in the installation groove 301. The shearing machine 1 is provided with a lower knife mechanism 8 on the front side of the rotating shaft 2. The lower knife mechanism 8 is used to cooperate with multiple shearing rotating disc cutters 3 to cut the metal strip. The lower knife mechanism 8 is connected to the rotating shaft 2 through a transmission component 9. A tensioning roller group 10 is provided inside the shearing machine 1, and a strip roll placement mechanism 11 is provided at the rear of the shearing machine 1.

[0023] like Figures 7 to 9As shown, a slider 401 is fixedly provided on one side of a plurality of filing members 4 close to the mounting groove 301. The slider 401 is rectangular in shape. The shearing rotary disc cutter 3 is provided with a slide groove 302 adapted thereto at the position corresponding to the slider 401. The cooperation between the slider 401 and the slide groove 302 can ensure the stability of the filing member 4 when sliding, and can also allow the shearing rotary disc cutter 3 to drive the filing member 4 to rotate.

[0024] like Figure 3 and Figure 4 As shown, the adjustment assembly 6 includes an annular member 601 slidably arranged on the outer surface of the fixed column 5, a support block 602 is fixedly arranged on the outer surface of the annular member 601, and the guide assembly 7 includes a connecting block 701 fixedly installed with the support block 602, and a fixing ring 702 is fixedly arranged at one end of the connecting block 701 away from the support block 602, and the end of the shearing rotating disc knife 3 is rotatably arranged inside the fixing ring 702, so that when the shearing rotating disc knife 3 rotates, the fixing ring 702 will not rotate with the shearing rotating disc knife 3. Figures 7 to 9 As shown, a wave groove 703 is formed on one side of the fixing ring 702 close to the filing member 4, and a guide column 402 is fixedly provided on one side of the filing member 4 close to the wave groove 703. The wave groove 703 is composed of a plurality of semicircular protrusions and a plurality of semicircular grooves surrounding the fixing ring 702 to form a circular ring. The cooperation between the wave groove 703 and the guide column 402 enables two adjacent filing members 4 to slide back and forth alternately, as shown in FIG. Figure 1 As shown, the shearing machine 1 is provided with waste absorbing mechanisms 14 at positions corresponding to the plurality of shearing rotary disc cutters 3 .

[0025] like Figure 1 and Figure 3 As shown, the transmission assembly 9 includes a first gear 901 fixedly mounted on one end of the lower knife mechanism 8, and a second gear 902 is fixedly mounted on the outer surface of the rotating shaft 2 on a side close to the first gear 901; a swing mechanism 13 is provided on the side of the shearing machine 1 close to the lower knife mechanism 8, and the swing mechanism 13 is used to control the lower knife mechanism 8 to swing, thereby utilizing the swing of the lower knife mechanism 8 to control the first gear 901 to mesh with or separate from the second gear 902.

[0026] like Figures 3 to 9As shown, the shearing rotary disc cutter 3 and the fixing ring 702 are both formed by splicing two semicircular rings, thereby facilitating the installation or separation of the shearing rotary disc cutter 3 and the rotating shaft 2. The two semicircular rings of the shearing rotary disc cutter 3 and the fixing ring 702 are both fixedly installed by bolts. When strips of different widths are required, the bolts on the shearing rotary disc cutter 3 and the fixing ring 702 are loosened. At this time, the shearing rotary disc cutter 3 spliced ​​by the two semicircular rings no longer clamps the rotating shaft 2. Then, the positions of the shearing rotary disc cutter 3, the guide assembly 7 and the adjustment assembly 6 can be adjusted as required. After the adjustment is completed, the bolts on the shearing rotary disc cutter 3 and the fixing ring 702 are tightened again to allow the shearing rotary disc cutter 3 to clamp the rotating shaft 2. When the rotating shaft 2 drives multiple shearing rotary disc cutters 3 to rotate, the cooperation between the wave groove 703 and the guide column 402 is utilized to make the two adjacent filing members 4 slide back and forth alternately, and then the filing members 4 rub the edge of the metal strip.

[0027] In summary: First, if Figures 4 to 9 As shown in the figure, by finely filing the edge of the metal strip, not only can the burrs be effectively removed, but also the finish of the edge of the metal strip can be significantly improved. The edge of the metal strip after filing is more flat and smooth, meeting the high standard surface treatment requirements, realizing the integration of cutting and deburring, and greatly improving the production efficiency; secondly, by staggered reciprocating sliding filing pieces 4, a certain amount of micro vibration will be introduced when the shearing rotating disc knife 3 rotates, and moderate vibration will help the filing piece 4 to remove burrs more effectively (vibration helps the filing block to enter the micro defects of the metal strip, thereby removing the burrs more thoroughly); thirdly, at the same time, slight vibration The vibration helps to clean the cutting area, making it easier to remove chips and reduce the reduction in cutting quality due to chip accumulation. For some materials that easily adhere to the cutting blade, vibration helps to reduce such adhesion and keep the cutting blade clean and sharp, thereby improving the cutting effect. The waste can then be sucked out through the waste absorption mechanism 14 to avoid debris remaining inside the equipment. Fourthly, the cutting force of the shearing rotating disc knife 3 can be enhanced by vibration, especially when cutting tough materials. Vibration can help the shearing rotating disc knife 3 penetrate the material better, as well as reduce the adhesion of the material to the cutting blade, reduce cutting resistance, and improve cutting efficiency.

[0028] The shearing machine 1, rotating shaft 2, lower knife mechanism 8, tensioning roller group 10, coil placement mechanism 11, driving member 12, swing mechanism 13 and waste absorption mechanism 14 described in the present application are well-known technologies in the technical field, so their specific structure and working principle are not described in detail.

[0029] The working process is as follows: S1, such as Figures 1 to 3As shown, when in use, the rotating shaft 2 is first controlled to rotate by the driving member 12, and then the metal strip is tightened by the tensioning roller group 10, and then the lower knife mechanism 8 and the rotating shaft 2 are rotated in opposite directions by the transmission component 9, so that the metal strip passes between the lower knife mechanism 8 and the rotating shaft 2, and then the material can be cut by using multiple shearing rotating disc knives 3; S2, such as Figure 3 , Figure 8 and Fig. 9 As shown, when the rotating shaft 2 drives the multiple shearing rotary disc cutters 3 to rotate, the cooperation between the wave groove 703 and the guide column 402 is used to make two adjacent filing members 4 slide back and forth alternately, and then the filing members 4 rub the edge of the metal strip; S3, such as Figures 4 to 9 As shown in the figure, by finely filing the edge of the metal strip, not only can the burrs be effectively removed, but also the finish of the edge of the metal strip can be significantly improved. The edge of the metal strip after filing is flatter and smoother, meeting the high standard surface treatment requirements, realizing the integration of cutting and deburring, and greatly improving production efficiency; S4, such as Figures 4 to 9 As shown, by staggered reciprocating sliding filing pieces 4, a certain amount of vibration will be introduced when the shearing rotary disc cutter 3 rotates, and moderate vibration will help the filing pieces 4 to remove burrs more effectively (vibration helps the filing blocks to enter the microscopic defects of the metal strip, thereby removing the burrs more thoroughly); S5, such as Figures 4 to 9 As shown, slight vibration helps to clean the cutting area, making it easier to remove the chips, reducing the reduction in cutting quality caused by chip accumulation. For some materials that are easy to adhere to the cutting blade, vibration helps to reduce such adhesion, keeping the cutting blade clean and sharp, thereby improving the cutting effect. Afterwards, the waste can be sucked out by the waste absorption mechanism 14 to avoid debris remaining inside the device; S6, such as Figures 4 to 9 As shown, the cutting force of the shearing rotating disc cutter 3 can be improved by vibration, especially when cutting tough materials. Vibration can help the shearing rotating disc cutter 3 to better penetrate the material, reduce the adhesion of the material to the cutting blade, reduce cutting resistance, and improve cutting efficiency.

Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
