Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, specifically a slitting wire cutting device. Background Technology

[0002] In the metal processing industry, metal strips are widely used in automobile manufacturing, home appliance production, construction engineering, and machinery processing. In these applications, metal strips of different specifications often need to be cut according to actual needs to meet the dimensional requirements of subsequent processes or product assembly. Typically, metal strips are uncoiled by a coiler and then processed through a slitting line. However, the length of the slitting strips is often not the final required size. Therefore, in actual production, precise length cutting of the metal strips is necessary to ensure production efficiency and product quality. Furthermore, efficient and precise cutting methods can reduce material waste, increase the automation level of the production line, reduce manual intervention, and improve the overall manufacturing level.

[0003] Currently, in the metal strip cutting process, the traditional method is to first measure the required cutting length, manually mark the metal strip, and then use a cutting knife to cut it. This method is prone to length errors and reduces product consistency. Utility Model Content

[0004] The purpose of this invention is to provide a slitting wire cutting device to solve at least one aspect of the problems and defects mentioned in the background art.

[0005] A slitting line cutting device is provided, including a frame, a first conveying component disposed on the frame, a bearing component disposed in the middle of the frame, a second conveying component disposed on the side of the frame away from the first conveying component, a limit component disposed on the second conveying component, and a cutting component disposed above the bearing component.

[0006] Furthermore, the first conveying component includes a conveying frame mounted on a machine frame. A drive motor is mounted on the conveying frame, and a drive roller is fixedly connected to the conveying end of the drive motor. The drive roller is rotatably connected to the conveying frame. After the drive motor starts, the drive roller rotates, contacts the surface of the metal strip, and generates friction, causing the metal strip to move forward in a set direction. Since the drive roller is directly controlled by the drive motor, precise speed control can be achieved, ensuring the stable forward movement of the metal strip and guaranteeing the accuracy of the cutting length. When the front end of the metal strip contacts the limiting component and reaches the preset length, the system controls the drive motor to stop, stopping the metal strip at the cutting position to ensure cutting accuracy. After the first conveying component stops, the supporting component rises to support the metal strip, and then the cutting component performs the cutting operation. After the cutting is completed, the second conveying component continues to transport the cut metal strip to the next process, which can avoid cutting length errors and improve product consistency.

[0007] Furthermore, an installation groove is provided below the conveyor frame, and a guide roller is rotatably connected in the installation groove. The guide roller can ensure that the metal strip enters the first conveying component along the set path. Since the guide roller can rotate freely, it can rotate with the metal strip as it passes through, reducing scratches or deformation caused by friction and improving processing quality.

[0008] Furthermore, a receiving groove is provided in the middle of the frame, and a bearing component is provided inside the receiving groove. The bearing component is installed in the receiving groove and can be raised and lowered to support the metal strip to be cut, providing stable support during the cutting process and ensuring cutting accuracy.

[0009] Furthermore, the bearing component includes a lifting cylinder, which is disposed in the receiving groove. The extension end of the lifting cylinder is fixedly connected to a support pad, and each support pad is provided with a rubber pad. When the first conveying component is running, the metal strip is conveyed at a uniform speed and passes through the bearing component position in mid-air. At this time, the lifting cylinder is in the retracted state, and the support pad is in a low position, which does not interfere with the normal conveying of the metal strip. When the metal strip reaches the cutting position, when the metal strip reaches the set length, the limit component is triggered, the first conveying component stops conveying, the metal strip stops at the cutting position, the lifting cylinder extends, pushes the support pad to rise, and the rubber pad is attached to the bottom of the metal strip, so that the metal strip remains stable during cutting.

[0010] Furthermore, the second conveying assembly includes a conveying seat, a conveying groove is provided on the frame, the conveying seat is disposed on the conveying groove, and several limiting rollers are rotatably connected to the upper and lower sides of the conveying seat. A limiting component is provided at the conveying end of the conveying seat. After cutting is completed, the limiting component no longer obstructs the movement of the metal strip, releasing the cut metal strip, which then enters the second conveying assembly. At this time, the upper and lower limiting rollers begin to rotate, conveying the metal strip to the next process.

[0011] Furthermore, the limiting component includes an electric slide rail, an electric slider slidably connected above the electric slide rail, a limiting frame above the electric slider, a servo motor above the limiting frame, a limiting plate fixedly connected to the output end of the servo motor, and a contact switch on the limiting plate. The metal strip is conveyed to the cutting station by the first conveying component and gradually approaches the limiting plate. When the front end of the metal strip contacts the limiting plate, the limiting plate swings slightly due to the pushing force of the metal strip, triggering the contact switch. The contact switch transmits a signal to the control system, instructing the first conveying component to stop operating, ensuring that the metal strip stops at the correct cutting position.

[0012] Furthermore, the cutting assembly includes a cutting frame mounted on a machine frame. Electric push rods are symmetrically arranged on the cutting frame, and a mounting plate is fixedly connected to the telescopic end of each electric push rod. A cutting blade is detachably connected to the mounting plate. The first conveying assembly feeds the metal strip into the cutting station. The limiting assembly triggers a conveying stop signal, causing the metal strip to stop. The carrying assembly rises, supporting the metal strip and placing it in a stable cutting position. The electric push rods extend, causing the mounting plate to move downwards, pushing the cutting blade to apply shearing force to the metal strip, allowing the cut metal strip to freely enter the second conveying assembly. The limiting assembly rotates, preventing the limiting plate from obstructing the cut metal strip, allowing it to be conveyed to the next process. After conveying, the limiting assembly rotates again, returning the limiting plate to its original position. At this point, the first conveying assembly restarts, continuing to convey the next metal strip. This process is repeated to complete the fixed-length cutting of the metal strip.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The metal strip to be cut is conveyed at a constant speed from the uncoiler or the previous process to the cutting station, ensuring stable progress. When the front end of the metal strip contacts the limiting component, the system detects that the set length has been reached, and the first conveying component stops conveying to ensure accurate cutting length. After the first conveying component stops, it rises to support the bottom of the metal strip to be cut, preventing material swaying or uneven force during cutting and ensuring cutting accuracy. After the supporting component is stable, it starts to cut the metal strip vertically, achieving precise segmentation. After cutting, the second conveying component starts to transport the cut metal strip to the next process, improving production efficiency. The cut metal strip enters the second conveying component and is conveyed at a constant speed to the next process. This avoids the length error that is easily caused by manual marking during the traditional cutting process, achieving fixed-length cutting of metal strips and improving product consistency.

[0023] However, there may be instances where unnecessary detailed descriptions are omitted. For example, detailed descriptions of well-known matters or repetitive descriptions of essentially the same structures may be omitted. This is to avoid unnecessarily lengthy descriptions and to facilitate understanding by those skilled in the art. Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.

[0024] Please see Figures 1-4 As shown in the present invention, a slitting wire cutting device includes a frame 1, a first conveying component 2 is provided on the frame 1, a bearing component 10 is provided in the middle of the frame 1, a second conveying component 3 is provided on the side of the frame 1 away from the first conveying component 2, a limiting component 4 is provided on the second conveying component 3, and a cutting component 5 is provided above the bearing component 10.

[0025] The metal strip to be cut is conveyed at a uniform speed from the uncoiler or the previous process to the cutting station, ensuring stable forward movement. When the front end of the metal strip contacts the limiting component 4, the system detects that the set length (the distance between the cutting component 5 and the limiting component 4) has been reached. The first conveying component 2 stops conveying, ensuring a constant cutting length. After the first conveying component 2 stops, it rises to support the bottom of the metal strip to prevent material swaying or uneven force during cutting, ensuring cutting accuracy. After the supporting component 10 provides stable support, it starts to vertically cut the metal strip, achieving precise segmentation and fixed-length cutting. After cutting is completed, the second conveying component 3 starts, limiting... Positioning component 4 no longer restricts the movement of the metal strip, conveying the cut metal strip to the next process, improving production efficiency. After the metal strip is cut, it enters the second conveying component 3 for conveying. Due to the upper and lower clamping of the limiting rollers 32, it will not tip over or deviate due to gravity. At this time, the limiting component 4 no longer restricts the movement of the cut metal strip. Through an external driving mechanism (not shown in the figure), the upper and lower limiting rollers 32 are driven to rotate, conveying the metal strip to the next process at a uniform speed. This can avoid the length error phenomenon that is easy to occur during the traditional cutting process when manually marking the cutting process, realize the fixed length cutting of the metal strip, and improve product consistency.

[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the first conveying component 2 includes a conveying frame 21, which is mounted on the frame 1. A drive motor 22 is mounted on the conveying frame 21, and a drive roller 23 is fixedly connected to the conveying end of the drive motor 22. The drive roller 23 is rotatably connected to the conveying frame 21. After the drive motor 22 starts, the drive roller 23 rotates, contacts the surface of the metal strip, and generates friction, causing the metal strip to move forward in a set direction. Since the drive roller 23 is directly controlled by the drive motor 22, precise speed control can be achieved, ensuring the stable forward movement of the metal strip and guaranteeing the accuracy of the cutting length. When the front end of the metal strip contacts the limiting component 4 and reaches the preset length, the system controls the drive motor 22 to stop, stopping the metal strip at the cutting position to ensure cutting accuracy. After the first conveying component 2 stops, the bearing component 10 rises to support the metal strip, and then the cutting component 5 performs the cutting operation. After the cutting is completed, the second conveying component 3 continues to transport the cut metal strip to the next process. This avoids the problem of manually marking the cutting error and then using a cutting blade in the traditional cutting process, which can easily lead to length errors and improve product consistency.

[0027] In one embodiment, see Figure 1 and Figure 2As shown, the frame 1 is also provided with a mounting groove 11, and a guide roller 12 is rotatably connected in the mounting groove 11. The guide roller 12 can ensure that the metal strip enters the first conveying component 2 along the set path. Since the guide roller 12 can rotate freely, it can rotate with the metal strip when it passes through, reducing scratches or deformation caused by friction and improving processing quality.

[0028] In one embodiment, see Figure 1 and Figure 2 As shown, a receiving groove 13 is provided in the middle of the frame 1, and a bearing component 10 is provided inside the receiving groove 13. The bearing component 10 is installed in the receiving groove 13 and can be raised and lowered to support the metal strip to be cut, providing stable support during the cutting process and ensuring cutting accuracy.

[0029] In one embodiment, see Figure 1 and Figure 4 As shown, the bearing component 10 includes a lifting cylinder 101, which is installed in the receiving groove 13. The extension end of the lifting cylinder 101 is fixedly connected to a support pad 102, and each support pad 102 is provided with a rubber pad 103. When the first conveying component 2 is running, the metal strip is conveyed at a constant speed and passes through the position of the bearing component 10 in mid-air. At this time, the lifting cylinder 101 is in the retracted state, and the support pad 102 is in a low position, which does not interfere with the normal conveying of the metal strip. When the metal strip reaches the cutting position, when the metal strip reaches the set length, the limit component 4 is triggered, the first conveying component 2 stops conveying, the metal strip stops at the cutting position, the lifting cylinder 101 extends, pushing the support pad 102 to rise, and the rubber pad 103 adheres to the bottom of the metal strip, so that the metal strip remains stable during cutting.

[0030] In one embodiment, see Figure 1 and Figure 2 As shown, the second conveying assembly 3 includes a conveying seat 31. A conveying groove 14 is provided on the frame 1. The conveying seat 31 is set on the conveying groove 14. Several limiting rollers 32 are rotatably connected to both the upper and lower sides of the conveying seat 31. A limiting component 4 is provided at the conveying end of the conveying seat 31. After cutting, the limiting component 4 no longer blocks the movement of the metal strip, releasing the cut metal strip. The metal strip enters the second conveying assembly 3. At this time, the upper limiting roller 32 and the lower limiting roller 32 start to rotate, conveying the metal strip to the next process. The upper limiting roller 32 and the lower limiting roller 32 are driven by an external driving mechanism (the external driving mechanism is mainly driven by a motor, which drives a synchronous belt or chain to drive several limiting rollers 32 to rotate independently), used to convey the cut metal strip to the next process.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the limiting component 4 includes an electric slide rail 41, an electric slider 42 slidably connected above the electric slide rail 41, a limiting frame 43 above the electric slider 42, a servo motor 44 above the limiting frame 43, and a limiting plate 45 fixedly connected to the output end of the servo motor 44. The limiting plate 45 is rotatably connected to the limiting frame 43, and a contact switch 46 is provided on the limiting plate 45. The metal strip is conveyed to the cutting station by the first conveying component 2 and gradually approaches the limiting plate 45. When the front end of the metal strip contacts the limiting plate 45, the limiting plate 45 swings slightly due to the pushing force of the metal strip, triggering the contact switch 46. The contact switch 46 transmits a signal to the control system, instructing the first conveying component 2 to stop operating, ensuring that the metal strip stops at the correct cutting position. After the first conveying component 2 stops, the supporting component 10 rises to support the metal strip. Then, the cutting component 5 vertically cuts the metal strip to achieve precise segmentation. After the cutting is completed, the servo motor 44 drives the limiting plate 45 to rotate, so that the limiting plate 45 no longer blocks the cut metal strip and releases the cut metal strip. The second conveying component 3 starts to transport the cut metal strip to the next process. The limiting component 4 returns to its initial state to prepare for the next metal strip cutting. The electric slider 42 can slide a certain distance along the electric slide rail 41 to adjust the position of the limiting frame 43. This allows the distance between the limiting plate 45 and the cutting blade 54 in the cutting component to be changed, thereby adjusting the cutting length of the metal strip to meet the cutting needs of metal strips of different specifications.

[0032] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the cutting assembly 5 includes a cutting frame 51, which is mounted on the frame 1. Electric push rods 52 are symmetrically arranged on the cutting frame 51. A mounting plate 53 is fixedly connected to the telescopic end of the electric push rod 52. A cutting blade 54 is detachably connected to the mounting plate 53. The length of the metal strip to be cut is the distance between the cutting blade 54 and the limiting plate 45 in the limiting assembly 4. The first conveying assembly 2 feeds the metal strip into the cutting station. The limiting assembly 4 triggers a conveying stop signal, causing the metal strip to stop. The carrying assembly 10 rises to support the metal strip, stabilizing it. At the cutting position, the electric push rod 52 extends, driving the mounting plate 53 to move downwards, pushing the cutting blade 54 to apply shearing force to the metal strip, allowing the cut metal strip to freely enter the second conveying assembly 3. The limiting assembly 4 rotates so that the limiting plate 45 no longer blocks the cut metal strip, allowing the cut metal strip to be conveyed to the next process. After conveying is completed, the limiting assembly 4 rotates so that the limiting plate 45 returns to its original position. At this time, the first conveying assembly 2 restarts and continues to convey the next section of metal strip. The above operation is repeated to complete the fixed-length cutting of the metal strip.

[0033] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
