Description

Technical Field

[0001] This utility model relates to the field of copper strip processing technology, specifically to a copper strip shearing device that facilitates the replacement of raw materials. Background Technology

[0002] In the process of processing copper strip, different production processes are required to process the copper strip in multiple layers, including cutting the copper strip. The copper strip shearing device is a kind of equipment used to cut the copper strip into specific sizes and shapes according to production needs to meet the usage requirements of different industries.

[0003] For example, patent CN221312685U discloses an adjustable copper plate cutting device, including a clamping plate. Through the setting of a fixing mechanism, the copper plate can be fixed by activating an electric telescopic rod and cooperating with the clamping plate. A spring and the clamping plate can be used to fix copper plates of different sizes, facilitating cutting. A rotating rod and a support rod are rotatably connected. Once the copper plate is fixed, it can be cut while rotating the fixing mechanism to achieve the desired trimming or shape. When used with an electric telescopic rod and a moving handle, the cutting machine can be moved up, down, left, and right, and the angle can be quickly adjusted to achieve the desired shape. When processing copper strips, due to the inconsistent shapes and storage methods of the copper strips, some copper strips can be laid flat, while others need to be rolled up. When cutting rolled copper strips, the strip roll is usually fixed to a rack or other object, and then the copper strip is pulled out for cutting. However, this fixing method is inconvenient for changing the copper strip roll.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing copper strip shearing device. Summary of the Invention

[0005] The purpose of this utility model is to provide a copper strip cutting device that facilitates the replacement of raw materials, in order to solve the problem mentioned in the background art that when cutting rolled copper strips, the copper strip roll is usually fixed on a frame or other object, and then the copper strip on the roll is pulled out for cutting. However, this fixing method is not convenient for replacing the copper strip roll.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a copper strip shearing device for easy material replacement, comprising a shearing seat, a movable seat mounted on one side of the shearing seat, a support frame mounted on the top of the shearing seat, a hydraulic cylinder mounted on the top of the support frame, and a cutter mounted on the output end of the hydraulic cylinder; a copper strip coil is provided on the other side of the shearing seat, with support blocks movably abutting at both ends of the copper strip coil, one support block being fixedly connected to the shearing seat and the other support block being slidably connected to the shearing seat; a moving mechanism for moving the support block on one side is provided on the support block.

[0007] Furthermore, the moving mechanism includes a moving plate, which is slidably connected to the interior of a support block on one side. A first spring is installed on one side of the moving plate, and one end of the first spring is fixedly connected to the interior of the support block. A locking post is installed on the other side of the moving plate, and a locking groove corresponding to the locking post is provided on the shearing seat.

[0008] Furthermore, the movable base is internally equipped with a length-fixing mechanism for cutting copper strips to a fixed length.

[0009] Furthermore, the length-fixing mechanism includes a threaded rod and a guide rod, both of which are rotatably connected inside the movable seat. A drive motor is installed on one side of the movable seat, and the output end of the drive motor is fixedly connected to the threaded rod. A clamping seat is threadedly connected to the outer wall of the threaded rod, and an ejector plate is installed at the bottom of the clamping seat. The other side of the clamping seat is slidably connected to the guide rod. An electric push rod is installed on the top of the clamping seat, and a clamping plate is fixedly connected to the output end of the electric push rod. Scale lines are provided on both sides of the top of the movable seat.

[0010] Furthermore, a cutting plate is slidably connected to the side of the shearing seat near the movable seat, and a second spring is fixedly connected to one side of the cutting plate. A sliding column is sleeved inside the second spring. One end of the second spring is fixedly connected to the shearing seat, a limit plate is provided at one end of the sliding column, and the other end of the sliding column is fixedly connected to the cutting plate.

[0011] Furthermore, the two sides of the cutter are slidably connected to the support frame via sliding blocks. A gear is installed on the side of the support frame away from the movable seat. The two sides of the gear are meshed with racks. One rack is fixedly connected to the sliding block via a connecting plate. A pressure roller is installed at the bottom of the rack on the other side. The rack on the other side is slidably connected to the support frame.

[0012] Furthermore, the shape of the ejector plate matches that of the cutting plate.

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

[0014] This copper strip shearing device, which facilitates the replacement of raw materials, compresses the first spring by pressing the moving plate, causing the locking pin to disengage from the slot. This allows the support block to slide easily, enabling the removal and replacement of the copper strip coil. After replacement, releasing the moving plate causes the first spring to return to its original state, pushing the locking pin back into the slot and securing the support block. This simple mechanical structure and operation greatly shortens the time required to replace the copper strip coil and improves production efficiency.

[0015] Furthermore, the electric push rod pushes the clamping plate and clamping seat to clamp the copper strip. The drive motor drives the threaded rod to rotate, causing the clamping seat to move linearly along the guide rod. The movement distance can be observed with the scale line to ensure that the copper strip is cut to a consistent length each time. The coordinated action of the ejector plate, cutting plate, and second spring allows for better adaptation to the position and state of the copper strip during clamping, further improving the accuracy of fixed-length cutting.

[0016] Furthermore, when the hydraulic cylinder pushes the cutter downward, the pressure roller moves upward through the meshing of the rack and gear; after cutting, the cutter rises and drives the pressure roller to move downward to press the copper strip. The pressure roller can fix the copper strip, making it easy for the clamping seat to clamp it accurately. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-7 This utility model provides the following technical solution: a copper strip shearing device for easy replacement of raw materials, including a shearing seat 1, a movable seat 2 installed on one side of the shearing seat 1, a support frame 4 installed on the top of the shearing seat 1, a hydraulic cylinder 5 installed on the top of the support frame 4, and a cutter 6 installed at the output end of the hydraulic cylinder 5; a copper strip roll 3 is provided on the other side of the shearing seat 1, and support blocks 7 are movably abutted at both ends of the copper strip roll 3, with one support block 7 fixedly connected to the shearing seat 1 and the other support block 7 slidably connected to the shearing seat 1; a moving mechanism for moving one side of the support block 7 is provided on the support block 7; the moving mechanism includes a moving plate 20, which is slidably connected to the inside of one side of the support block 7, a first spring 21 is installed on one side of the moving plate 20, one end of the first spring 21 is fixedly connected to the inside of the support block 7, and a locking post 22 is installed on the other side of the moving plate 20, with a locking groove corresponding to the locking post 22 opened on the shearing seat 1.

[0027] When it is necessary to replace the copper strip roll 3, press the moving plate 20 on the side of the support block 7 away from the moving seat 2. At this time, the first spring 21 is compressed under the action of the moving plate 20. The movement of the moving plate 20 will simultaneously drive the locking pin 22 to disengage from the slot of the shear seat 1. At this time, the slidably connected support block 7 can be slid on the shear seat 1. One end of the copper strip is movably abutting against the inside of the support block 7. Therefore, after the support block 7 on one side moves, the copper strip roll 3 will disengage from the support block 7 on one side, so that the copper strip roll 3 can be taken out for replacement. After the replacement is completed, release the moving plate 20, the first spring 21 returns to its original state, pushes the moving plate 20 to move outward, and the locking pin 22 is locked into the slot of the shear seat 1 again to fix the support block 7 and ensure the stable placement of the copper strip roll 3.

[0028] Example 2: Based on Example 1, a fixed-length mechanism is also disclosed, the specific structure of which is as follows:

[0029] The length-fixing mechanism includes a threaded rod 9 and a guide rod 10, both of which are rotatably connected to the interior of the movable seat 2. A drive motor 8 is installed on one side of the movable seat 2, and the output end of the drive motor 8 is fixedly connected to the threaded rod 9. A clamping seat 11 is threadedly connected to the outer wall of the threaded rod 9. An ejector plate 12 is installed at the bottom of the clamping seat 11, and the other side of the clamping seat 11 is slidably connected to the guide rod 10. An electric push rod 14 is installed on the top of the clamping seat 11, and a clamping plate 13 is fixedly connected to the output end of the electric push rod 14. Scale lines are provided on both sides of the top of the movable seat 2. A cutting plate 15 is slidably connected to the side of the shearing seat 1 closest to the movable seat 2. A second spring 17 is fixedly connected to one side of the cutting plate 15. A sliding column 16 is sleeved inside the second spring 17. One end of the second spring 17 is fixedly connected to the shearing seat 1. A limit plate is provided at one end of the sliding column 16, and the other end of the sliding column 16 is fixedly connected to the cutting plate 15.

[0030] When it is necessary to cut copper strip to a fixed length, the electric push rod 14 is activated, and its output end pushes the clamping plate 13 downward to cooperate with the clamping seat 11 to clamp one end of the copper strip. After clamping, the drive motor 8 is activated, and the output end of the drive motor 8 drives the threaded rod 9 to rotate. When the threaded rod 9 rotates, the clamping seat 11 will move linearly along the guide rod 10 under the action of the thread of the threaded rod 9. At this time, the movement distance of the clamping seat 11 can be observed with the scale line to ensure that the length of the copper strip is consistent each time. When clamping the copper strip, the clamping seat 11 should first be moved to a position close to the cutter 6. When the clamping seat 11 moves, the ejector plate 12 inside it will... Synchronous movement: When the clamping seat 11 moves to the designated position, the ejector plate 12 contacts the cutting plate 15. At this time, the clamping seat 11 continues to move, causing the ejector plate 12 to push the cutting plate 15 to slide. At this time, the movement of the cutting plate 15 will compress the second spring 17. When the ejector plate 12 moves to below one end of the copper strip, the electric push rod 14 can be activated to clamp the cutting point of the copper strip. Then, the clamping seat 11 is moved to pull the copper strip out a certain distance and cut it. After the ejector plate 12 moves away from the cutting plate 15, the second spring 17 is no longer compressed, thereby restoring its elasticity and driving the cutting plate 15 to reset. The movement distance of the cutting plate 15 is limited by the limiting plate set on the sliding column 16.

[0031] Example 3: Based on Example 1, a gear 18 mechanism is also disclosed, the specific structure of which is as follows:

[0032] The two sides of the cutter 6 are slidably connected to the support frame 4 via sliding blocks. A gear 18 is installed on the side of the support frame 4 away from the moving seat 2. The two sides of the gear 18 are meshed with racks 19. One rack 19 is fixedly connected to the sliding block via a connecting plate. A pressure roller 23 is installed at the bottom of the rack 19 on the other side. The rack 19 on the other side is slidably connected to the support frame 4. The shape of the ejector plate 12 matches that of the cutting plate 15.

[0033] When the hydraulic cylinder 5 is activated, its output end pushes the cutter 6 downward. The sliding blocks on both sides of the cutter 6 slide downward, and the rack 19 connected to the sliding block also moves downward. Through meshing with the gear 18, it drives the rack 19 on the other side to move upward, thereby causing the pressure roller 23 to move upward. After the cutting is completed, the hydraulic cylinder 5 drives the cutter 6 to rise, thereby causing the rack 19 connected to the sliding block to move upward, while the rack 19 on the other side moves downward, thereby driving the pressure roller 23 to move downward and pressing the copper strip. Then, when the ejector plate 12 pushes the cutting plate 15 to move, the copper strip will not move with the cutting plate 15 but will be fixed by the pressure roller 23, making it easy for the clamping seat 11 to clamp the copper strip.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
