Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery production technology, specifically a rolling tool. Background Technology

[0002] In lead-acid battery R&D testing, the plates coated with lead paste need to be rolled to ensure the lead paste is compacted and of uniform thickness to verify the effectiveness of the lead paste formulation. Existing similar fixtures (such as the fixture in patent publication number CN209515854U) have significant drawbacks: First, spacing adjustment relies on manual disassembly of the roller support, replacement of shims, or tightening of multiple bolts, which is cumbersome and time-consuming. The spacing accuracy depends entirely on the operator's experience, and deviations can easily lead to the plate thickness not meeting the test requirements, increasing the cost of ineffective testing. Second, using a manual crank or a regular motor to drive the roller is problematic. Manual cranks are prone to unstable speeds, and regular drive structures are prone to interrupting power transmission when adjusting the spacing, causing jerks in the rolling process, affecting the uniformity of lead paste compaction, and failing to meet the testing needs of frequent switching of plate thicknesses in the laboratory. Summary of the Invention

[0003] The purpose of this invention is to provide a rolling tool to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A rolling mill fixture includes: a U-shaped frame, with guide plates slidably mounted at both ends of the U-shaped frame, a first rolling column rotatably mounted between the two sets of guide plates, and a second rolling column disposed at the lower end of the U-shaped frame; a first gear is rotatably mounted at one end of the shaft of the first rolling column, and a second gear is rotatably mounted at one end of the shaft of the second rolling column, both the first gear and the second gear meshing with a transmission mechanism; the transmission mechanism is slidably mounted in a guide rail groove, the guide rail groove being formed at one end of an extension plate, and the extension plate being fixedly mounted at one end of the U-shaped frame.

[0005] In the aforementioned roller pressing fixture, when the first roller pressing column moves up and down within the U-shaped frame via the guide plate, the transmission mechanism can maintain its meshing with the first gear and the second gear through its own rotational movement and sliding movement within the guide rail groove.

[0006] In the aforementioned rolling fixture, an electric push rod is fixedly installed on the upper surface of the U-shaped frame, and the piston rod of the electric push rod slides through into the interior of the U-shaped frame, with the end of the piston rod fixedly connected to the upper surface of the guide plate.

[0007] In the aforementioned roller pressing fixture, the other end of the second roller pressing column is fixedly connected to the output shaft of the motor, and the motor is fixedly installed at one end of the U-shaped frame.

[0008] The aforementioned roll forming fixture includes: a transmission mechanism comprising a guide rail rod slidably mounted in a guide rail groove; a Y-shaped frame rotatably mounted on one end of the guide rail rod, and two sets of third gears rotatably mounted on one end of the Y-shaped frame, the two sets of third gears meshing with each other; the other end of one set of third gears meshes with a first gear, and the other end of the other set of third gears meshes with a second gear.

[0009] In the aforementioned rolling fixture: a guide rod is fixedly installed inside the guide rail groove, and the guide rod slides through the guide rail rod; a spring is fitted on the outer surface of the guide rod, one end of the spring is fixedly connected to one end of the guide rail groove, and the other end of the spring is fixedly connected to one end of the guide rail rod, so as to apply an elastic tension to the guide rail rod and the Y-shaped frame through the spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Simplified spacing adjustment and improved accuracy: The electric push rod drives the guide plate and the first roller column to rise and fall, replacing the traditional manual adjustment method of disassembling the bracket and tightening bolts, reducing operation steps; and the electric push rod has stable power output, avoiding spacing deviation caused by experience differences during manual adjustment, reducing ineffective roller pressing caused by inaccurate spacing, and adapting to the laboratory's requirements for electrode thickness accuracy.

[0011] Ensuring continuous transmission and improving work efficiency: The transmission mechanism achieves adaptive gear meshing during the lifting and lowering of the first roller column through the sliding of the guide rail rod, the rotation of the Y-shaped frame, and the elastic tension of the spring. No manual intervention is required to adjust the transmission components, avoiding downtime caused by power transmission interruption, ensuring the continuity of roller pressing operations. It is especially suitable for laboratory scenarios where different thickness plates are frequently switched, reducing adjustment time and improving test efficiency.

[0012] Stable rolling process to ensure electrode quality: The motor provides continuous and stable power for rolling, replacing the traditional manual crank and avoiding speed fluctuations; at the same time, the power transmission path of "motor → gear set → two rolling columns" ensures that the first and second rolling columns rotate synchronously relative to each other, so that the electrode is subjected to uniform force during the rolling process, improves the compaction effect of lead paste, ensures consistent electrode thickness, and provides reliable electrode samples for formulation testing.

[0013] Improve transmission stability and extend equipment life: The guide rod in the guide rail groove restricts the sliding direction of the guide rail rod, avoiding gear meshing misalignment caused by transmission mechanism deviation; the elastic tension of the spring keeps the third gear close to the first and second gears, reducing meshing clearance, avoiding transmission jerking or slippage, reducing gear wear, extending the service life of tooling, and ensuring the stability of roller pressing during long-term use.

[0016] 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.

[0017] Please see Figures 1-3 This embodiment provides a roll forming fixture, including: a U-shaped frame 1, with guide plates 102 slidably installed at both ends of the U-shaped frame 1, a first roll forming column 103 rotatably installed between the two sets of guide plates 102, and a second roll forming column 104 provided at the lower end of the U-shaped frame 1; a first gear 107 is rotatably installed at one end of the shaft of the first roll forming column 103, and a second gear 108 is rotatably installed at one end of the shaft of the second roll forming column 104, both the first gear 107 and the second gear 108 meshing with a transmission mechanism 2; the transmission mechanism 2 is slidably installed in a guide rail groove 109, the guide rail groove 109 being opened at one end of an extension plate 106, and the extension plate 106 being fixedly installed at one end of the U-shaped frame 1.

[0018] This solution uses a U-shaped frame 1 to provide installation support for the overall structure. A guide plate 102 is slidably installed inside the U-shaped frame 1, which can drive the first roller 103, which is rotatably installed between two sets of guide plates 102, to rise and fall. This adjusts the distance between the first roller 103 and the second roller 104 located at the lower end of the U-shaped frame 1, adapting to the rolling requirements of electrode plates of different thicknesses. Simultaneously, the first gear 107 at one end of the shaft of the first roller 103 and the second gear 108 at one end of the shaft of the second roller 104 are both slidably installed on the extension plate. The transmission mechanism 2 is engaged in the guide rail groove 109 of the slotted body 106. The extension plate 106 is fixed to one end of the U-shaped frame 1 to provide an installation base for the transmission mechanism 2. This structural design can ensure that when the spacing of the first roller pressing column 103 is adjusted, the transmission mechanism 2 can always maintain the meshing state with the first gear 107 and the second gear 108 by changing the position of the sliding adapter gear in the guide rail groove 109, avoiding interruption of power transmission, ensuring that the first roller pressing column 103 and the second roller pressing column 104 work continuously and synchronously, and meeting the basic functional requirements of the electrode plate rolling.

[0019] Specifically, in this embodiment, when the first roller pressing column 103 moves up and down within the U-shaped frame 1 via the guide plate 102, the transmission mechanism 2 maintains engagement with the first gear 107 and the second gear 108 through its own rotation and sliding motion within the guide rail groove 109. This solution further limits that when the first roller pressing column 103 moves up and down within the U-shaped frame 1 via the guide plate 102, the transmission mechanism 2 maintains engagement with the first gear 107 and the second gear 108 through its own rotation and sliding motion within the guide rail groove 109. This limitation allows the first roller pressing column 103 to maintain engagement throughout the entire process of adjusting the spacing without manual intervention to adjust the position of the transmission components, relying solely on the movement of the transmission mechanism 2 to avoid machine stoppage due to transmission disconnection caused by spacing adjustment. This ensures the continuity of the roller pressing operation, reduces operational steps, and improves operational efficiency, making it particularly suitable for applications requiring frequent changes in electrode thickness.

[0020] Specifically, in this embodiment, an electric push rod 101 is fixedly installed on the upper surface of the U-shaped frame 1. The piston rod of the electric push rod 101 slides through the interior of the U-shaped frame 1, and the end of the piston rod is fixedly connected to the upper surface of the guide plate 102. This solution uses the extension and retraction of the piston rod of the electric push rod 101 to provide power, driving the guide plate 102 and the first roller 103 to rise and fall stably. This replaces the traditional manual disassembly of the bracket and tightening of bolts adjustment method, simplifying the adjustment operation of the distance between the first roller 103 and the second roller 104. At the same time, the power output of the electric push rod 101 is stable, which can avoid the distance deviation caused by differences in operating experience during manual adjustment, improve the stability and accuracy of distance adjustment, and reduce the ineffective roller pressing caused by inaccurate distance.

[0021] Specifically, in this embodiment, the other end of the second roller pressing column 104 is fixedly connected to the output shaft of the motor 105, and the motor 105 is fixedly installed at one end of the U-shaped frame 1. This solution utilizes the continuous and stable power provided by the motor 105 to directly drive the second roller pressing column 104 to rotate by fixing the other end of the second roller pressing column 104 to the output shaft of the motor 105 fixedly installed at one end of the U-shaped frame 1. Then, through the meshing of the second gear 108 at one end of the shaft of the second roller pressing column 104 with the transmission mechanism 2, the power is transmitted to the first gear 107 and the first roller pressing column 103, achieving synchronous relative rotation between the first roller pressing column 103 and the second roller pressing column 104. This design replaces the traditional manual crank drive method, avoiding the problem of unstable speed during manual drive, ensuring consistent speed of the two roller pressing columns, making the electrode plate uniformly stressed during the rolling process, improving the lead paste compaction effect, and ensuring consistent electrode plate thickness.

[0022] Specifically, in this embodiment, the transmission mechanism 2 includes a guide rail 201, which is slidably installed in the guide rail groove 109. A Y-shaped frame 202 is rotatably installed at one end of the guide rail 201, and two sets of third gears 203 are rotatably installed at one end of the Y-shaped frame 202. The two sets of third gears 203 mesh with each other. The other end of one set of third gears 203 meshes with the first gear 107, and the other end of the other set of third gears 203 meshes with the second gear 108. In this scheme, the guide rail 201 of the transmission mechanism 2 is slidably installed in the guide rail groove 109 and can slide along the direction of the guide rail groove 109 to adapt to the position change of the first gear 107. The Y-shaped frame 202, which is rotatably installed at one end of the guide rail 201, can rotate flexibly to adjust the angle of the two sets of third gears 203 rotatably installed at one end. The two sets of third gears 203 mesh with each other and respectively mesh with the first gear 107 and the second gear 108, forming a complete power transmission path. This structure allows the sliding of the guide rail rod 201 and the rotation of the Y-shaped frame 202 to adjust the position and angle of the third gear 203 when the first roller pressing column 103 moves up and down, driving the first gear 107 to move. This ensures that the third gear 203 is always precisely meshed with the first gear 107 and the second gear 108, guaranteeing the stable transmission of power from the second gear 108 to the first gear 107, allowing the two roller pressing columns to rotate synchronously continuously, and improving the transmission adaptability and stability.

[0023] Specifically, in this embodiment, a guide rod 205 is fixedly installed inside the guide rail groove 109, and the guide rod 205 slides through the guide rail rod 201; a spring 204 is fitted on the outer surface of the guide rod 205, one end of the spring 204 is fixedly connected to one end of the guide rail groove 109, and the other end of the spring 204 is fixedly connected to one end of the guide rail rod 201, so as to apply elastic tension to the guide rail rod 201 and the Y-shaped frame 202 through the spring 204. This solution, by fixing a guide rod 205 inside the guide rail groove 109 and having the guide rod 205 slide through the guide rail rod 201, restricts the sliding direction of the guide rail rod 201, preventing it from shifting during sliding and ensuring the overall stability of the transmission mechanism 2. This, in turn, ensures the precise meshing position of the third gear 203 with the first gear 107 and the second gear 108. Simultaneously, the springs 204 fitted on the outer surface of the guide rod 205 are connected at both ends to one end inside the guide rail groove 109 and one end of the guide rail rod 201, respectively. This applies elastic tension to the guide rail rod 201 and the Y-shaped frame 202, ensuring that the two sets of third gears 203 always remain in close contact with the first gear 107 and the second gear 108, reducing meshing clearance, preventing jerking or slippage during transmission, ensuring the continuity and smoothness of power transmission, and improving the stability of the rolling operation.

[0024] Working principle: 1. Overall support and adjustment base: The U-shaped frame 1 provides installation support for the entire tooling. The guide plates 102 slidably installed at both ends can move vertically along the inner side wall of the U-shaped frame 1. The first roller column 103 rotatably installed between the two sets of guide plates 102 can rise and fall synchronously with the guide plates 102, thereby changing the distance between it and the second roller column 104 fixedly installed at the lower end of the U-shaped frame 1, so as to meet the rolling requirements of electrode plates of different thicknesses.

[0025] Power input and transmission: The motor 105, fixed at one end of the U-shaped frame 1, provides power to the roller press. The output shaft of the motor 105 is directly fixedly connected to one end of the second roller press column 104, which can drive the second roller press column 104 to rotate. The second gear 108 installed at the other end of the shaft of the second roller press column 104 meshes with a set of third gears 203 in the transmission mechanism 2. At the same time, the first gear 107 installed at one end of the shaft of the first roller press column 103 meshes with another set of third gears 203 in the transmission mechanism 2. The two sets of third gears 203 mesh with each other, forming a power transmission path of "motor 105 → second roller press column 104 → second gear 108 → third gear 203 → first gear 107 → first roller press column 103", realizing the synchronous relative rotation of the first roller press column 103 and the second roller press column 104.

[0026] Transmission adaptive adjustment: The guide rail rod 201 of the transmission mechanism 2 is slidably installed in the guide rail groove 109 opened in the extension plate 106 (the extension plate 106 is fixed to one end of the U-shaped frame 1, providing an installation base for the transmission mechanism 2). The Y-shaped frame 202, which is rotatably installed at one end of the guide rail rod 201, can rotate flexibly and adjust the angle of the two sets of third gears 203 according to the position change of the first gear 107 caused by the rise and fall of the first roller pressure column 103; at the same time, the guide rod 205 fixed in the guide rail groove 109 slides through the guide rail rod 201. The guide rod 201 can be restricted to slide in a certain direction to avoid deviation. The spring 204 on the outer surface of the guide rod 205 is connected at both ends to the inner wall of the guide groove 109 and the guide rod 201, respectively. It can apply elastic tension to the guide rod 201 and the Y-shaped frame 202, so that the two sets of third gears 203 are always in close contact with the first gear 107 and the second gear 108. When the first roller column 103 is raised and lowered to adjust the distance, the transmission mechanism 2 can slide through the guide rod 201 and rotate with the Y-shaped frame 202 to keep the gear meshing state uninterrupted.

[0027] Spacing adjustment power: The piston rod of the electric push rod 101 fixed on the upper surface of the U-shaped frame 1 slides through the U-shaped frame 1 and is fixedly connected to the upper surface of the guide plate 102. The extension and retraction of the piston rod of the electric push rod 101 can drive the guide plate 102 to rise and fall stably, thereby controlling the rising and falling amplitude of the first roller pressure column 103 and realizing the precise adjustment of the spacing between the two roller pressure columns.

[0028] How to use: 1. Adjusting the roller gap: Start the electric push rod 101. The piston rod of the electric push rod 101 extends and retracts vertically, driving the guide plate 102 connected to it to slide along the inner wall of the U-shaped frame 1. The guide plate 102 further drives the first roller column 103 between the two sets of guide plates 102 to rise and fall, adjusting the gap between the first roller column 103 and the second roller column 104. During this process, the first gear 107 moves synchronously with the first roller column 103. The guide rail rod 201 of the transmission mechanism 2 slides along the guide rail groove 109, and the Y-shaped frame 202 rotates. With the elastic tension of the spring 204, the two sets of third gears 203 are always meshed with the first gear 107 and the second gear 108 until the gap reaches the preset thickness of the plate to be rolled. Then, turn off the electric push rod 101.

[0029] Start the roller pressing power: Start the motor 105 fixed at one end of the U-shaped frame 1. The output shaft of the motor 105 drives the second roller pressing column 104 to rotate. The second roller pressing column 104 drives the second gear 108 to rotate. Through the meshing third gear 203, the power is transmitted to the first gear 107, which in turn drives the first roller pressing column 103 to rotate, so that the first roller pressing column 103 and the second roller pressing column 104 keep rotating synchronously relative to each other.

[0030] Perform electrode plate rolling: Place the electrode plate to be rolled with lead paste in the gap inlet between the first roller 103 and the second roller 104. The electrode plate is fed into the gap under the synchronous rotation of the two rollers. The lead paste is compacted and the thickness is uniform. After rolling is completed, the electrode plate is taken out from the gap outlet. If it is necessary to switch to electrode plates of different thicknesses, repeat the above steps of adjusting the gap.

[0031] The overall technical effects of this roller pressing fixture are as follows: 1. Simplify spacing adjustment and improve accuracy: The electric push rod 101 drives the guide plate 102 and the first roller column 103 to rise and fall, replacing the traditional manual adjustment method of disassembling the bracket and tightening bolts, reducing operation steps; and the electric push rod 101 has stable power output, avoiding spacing deviation caused by experience differences during manual adjustment, reducing ineffective roller pressing caused by inaccurate spacing, and adapting to the laboratory's requirements for electrode thickness accuracy.

[0032] To ensure continuous transmission and improve work efficiency: The transmission mechanism 2 achieves adaptive gear meshing when the first roller pressing column 103 is raised and lowered by sliding of the guide rail rod 201, rotation of the Y-shaped frame 202 and elastic tension of the spring 204. No manual intervention is required to adjust the transmission components, avoiding downtime caused by power transmission interruption, ensuring the continuity of roller pressing operation. It is especially suitable for laboratory scenarios where different thickness plates are frequently switched, reducing adjustment time and improving test efficiency.

[0033] Stable rolling process to ensure electrode quality: Motor 105 provides continuous and stable power for rolling, replacing the traditional manual crank and avoiding speed fluctuations; at the same time, the power transmission path of "motor 105 → gear set → two rolling columns" ensures that the first rolling column 103 and the second rolling column 104 rotate synchronously relative to each other, so that the electrode is subjected to uniform force during the rolling process, improves the compaction effect of lead paste, ensures consistent electrode thickness, and provides reliable electrode samples for formulation testing.

[0034] To improve transmission stability and extend equipment life: the guide rod 205 in the guide rail groove 109 restricts the sliding direction of the guide rail rod 201, preventing the transmission mechanism 2 from shifting and causing gear meshing misalignment; the elastic tension of the spring 204 keeps the third gear 203 in close contact with the first gear 107 and the second gear 108, reducing meshing clearance, preventing transmission jerking or slippage, reducing gear wear, extending the service life of the tooling, and ensuring the stability of the roller pressing during long-term use.
