Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, and in particular to a wire rolling drive device. Background Technology

[0002] Flattening wire into flat wire is a common process in metal wire processing. This involves applying pressure to a round wire using upper and lower rolling rollers, transforming its cross-section from a circle into a specified flat shape to meet dimensional and surface quality requirements. In actual production, the drive system of the rolling mechanism directly affects roller speed consistency, roller gap stability, and processing accuracy. However, existing rolling equipment drive structures often suffer from insufficient stability: insufficient rigidity or large backlash in the transmission chain leads to asynchronous speeds of the upper and lower rollers; insufficient positioning accuracy of the shaft system and supports causes eccentricity and uneven loading, resulting in uneven flat wire thickness, surface scratches, dimensional fluctuations, and a decrease in yield. This also increases equipment maintenance frequency and operating costs, limiting further improvements in production efficiency and processing accuracy. Therefore, new improvements are needed to the existing wire rolling structure. Utility Model Content

[0003] To solve the above problems, this utility model has a compact overall structure and high synchronization accuracy, which can significantly improve the surface quality and dimensional consistency of wire, reduce wear of calendering rolls and bearings, reduce vibration and noise, improve production stability and service life, and is a high-efficiency flattening wire calendering drive device that can adapt to different materials and process requirements.

[0004] The technical solution adopted by this utility model is: a wire rolling drive device, including a rolling mechanism, a transmission connection mechanism, a transmission synchronization mechanism, and an output mechanism. The rolling mechanism is provided with a rolling support frame, an upper rolling roller, and a lower rolling roller.

The transmission connection mechanism is provided with a first coupling and a second coupling. The first coupling is used to connect the first output shaft to the upper rolling roller, and the second coupling is used to connect the second output shaft to the lower rolling roller.

[0005] A further improvement to the above scheme is that two calendering support frames are provided, and the two calendering support frames are respectively located at both ends of the upper calendering roll and the lower calendering roll, for mounting the two ends of the upper calendering roll and the lower calendering roll.

[0006] A further improvement to the above scheme is that the calendering support frame is provided with a calendering groove, the calendering groove is provided with an upper slide block and a lower slide block, the upper calendering roll is connected to the upper slide block through a bearing, and the lower calendering roll is connected to the lower slide block through a bearing.

[0007] A further improvement to the above scheme is that the calendering support frame is provided with an adjustment component, which is located above the calendering chute and is used to adjust the upper slider to slide along the calendering chute to adjust the distance between the upper calendering roll and the lower calendering roll.

[0008] A further improvement to the above scheme is that the first coupling includes a first input end, a first eccentric connector and a first output end connected in sequence. The first eccentric connector is used to connect the first input end and the first output end. The first input end is connected to the first output shaft and the first output end is connected to the upper calendering roller.

[0009] A further improvement to the above solution is that the first eccentric connector is provided with a first connecting piece, and the first connecting piece is provided with a first adjusting groove and a first fixing screw, so as to connect the first eccentric connector to the first output end through the first connecting piece.

[0010] A further improvement to the above scheme is that the second coupling includes a second input end, a second eccentric connector and a second output end connected in sequence. The second eccentric connector is used to connect the second input end and the second output end. The second input end is connected to the second output shaft and the second output end is connected to the lower calendering roll.

[0011] A further improvement to the above scheme is that the second eccentric connector is provided with a second connecting piece, and the second connecting piece is provided with a second adjusting groove and a second fixing screw, so as to connect the second eccentric connector to the second output end through the second connecting piece.

[0012] A further improvement to the above scheme is that the transmission synchronization mechanism is provided with a transmission box, the gear is disposed in the transmission box, the input shaft is connected to the first output shaft, the second output shaft is located above the first output shaft and is connected to the first output shaft through the gear, so that the first output shaft and the second output shaft are synchronously transmitted.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-4 As shown, in one embodiment of this utility model, a wire rolling drive device is provided, including a rolling mechanism 1, a transmission connection mechanism 2, a transmission synchronization mechanism 3, and an output mechanism 4. The rolling mechanism 1 is provided with a rolling support frame 11, an upper rolling roller 12, and a lower rolling roller 13. The upper rolling roller 12 and the lower rolling roller 13 are both disposed on the rolling support frame 11. The transmission synchronization mechanism 3 is located on one side of the rolling support frame 11. The transmission synchronization mechanism 3 includes an input shaft 31, a first output shaft 32, and a second output shaft 33. A gear synchronous transmission connection is provided between the first output shaft 32 and the second output shaft 33. The input shaft 31 is connected to the output mechanism 4. The transmission connection mechanism 2 is provided with a first coupling 21 and a second coupling 22. The first coupling 21 is used to connect the first output shaft 32 to the upper rolling roller 12, and the second coupling 22 is used to connect the second output shaft 33 to the lower rolling roller 13. This embodiment achieves rigid synchronous transmission of the upper and lower calendering rollers 13 by centrally arranging the transmission synchronization mechanism 3 on one side of the calendering support frame 11 and synchronously connecting the first output shaft 32 and the second output shaft 33 with gears. This effectively eliminates relative slippage and speed difference between the two rollers, ensuring the speed consistency and flattening deformation uniformity of the wire during the calendering process. The reliable transmission connection between the input shaft 31 and the output mechanism 4 enables centralized power input and stable torque output, improving drive efficiency. The first coupling 21 and the second coupling 22 connect the upper and lower calendering rollers 13 respectively, facilitating compensation for axial and angular deviations, reducing transmission errors, and simplifying disassembly and maintenance, thus reducing equipment downtime. The overall structure is compact and has high synchronization accuracy, significantly improving the surface quality and dimensional consistency of the wire, reducing wear on the calendering rollers and bearings, reducing vibration and noise, improving production stability and service life, and adapting to efficient flattening processing for different materials and process requirements.

[0020] Two calendering support frames 11 are provided, respectively located at both ends of the upper calendering roll 12 and the lower calendering roll 13, for mounting the ends of the upper calendering roll 12 and the lower calendering roll 13. Specifically, the calendering support frame 11 is provided with a calendering groove 111, on which an upper slider 112 and a lower slider 113 are provided. The upper calendering roll 12 is connected to the upper slider 112 via bearings, and the lower calendering roll 13 is connected to the lower slider 113 via bearings. In this embodiment, the two end support frames provide rigid support and positioning for both ends of the roll, effectively dispersing and bearing the radial and bending moment loads during the calendering process, significantly reducing the deflection and axial rotation of the calendering roll, ensuring the consistency of the roll gap along the entire length, thereby improving the thickness uniformity and dimensional stability of the flattened wire. The calendering groove 111, in conjunction with the upper and lower sliders 113, provides the roll end with a controlled radial and axial alignment mechanism, facilitating the adjustment of concentricity and gap during assembly, and also compensating for thermal expansion or axial displacement, reducing local stress concentration caused by off-center loading. The upper and lower calendering rolls 13 are connected to the sliders through bearings, reducing rotational friction and vibration, improving transmission smoothness, reducing energy consumption and wear on bearings and roll surfaces, and extending the service life of key components.

[0021] An adjustment component 114 is provided on the calendering support frame 11. The adjustment component 114 is located above the calendering chute 111 and is used to adjust the upper slider 112 to slide along the calendering chute 111 to adjust the gap between the upper calendering roll 12 and the lower calendering roll 13. In this embodiment, the roll gap can be quickly and accurately adjusted, allowing for fine control of the flattening thickness during processing, thereby significantly improving the dimensional consistency and flatness of the finished wire. Secondly, it can compensate for gap changes caused by roll surface wear, bearing settlement, or thermal expansion, maintaining processing stability during long-term operation and reducing batch-to-batch deviations. The adjustment component 114 facilitates rapid adjustment when changing materials, process parameters, or product specifications, shortening changeover and debugging time, and improving production flexibility and equipment utilization.

[0022] The first coupling 21 includes a first input end 211, a first eccentric connector 212, and a first output end 213 connected in sequence. The first eccentric connector 212 connects the first input end 211 to the first output end 213. The first input end 211 is connected to the first output shaft 32, and the first output end 213 is connected to the upper calendering roller 12. The first eccentric connector 212 is provided with a first connecting piece 2121, which has a first adjusting groove (not shown) and a first fixing screw 2122 for connecting the first eccentric connector 212 to the first output end 213 via the first connecting piece 2121. Specifically, the second coupling 22 includes a second input end 221, a second eccentric connector 222, and a second output end 223 connected in sequence. The second eccentric connector 222 connects the second input end 221 to the second output end 223. The second input end 221 is connected to the second output shaft 33, and the second output end 223 is connected to the lower calendering roller 13. The second eccentric connector 222 is provided with a second connecting piece 2221. The second connecting piece 2221 is provided with a second adjusting groove (not shown in the figure) and a second fixing screw 2222, so as to connect the second eccentric connector 222 to the second output end 223 through the second connecting piece 2221. In this embodiment, both the first and second couplings 22 adopt a structure consisting of an input end, an eccentric connector, and an output end. The eccentric connector is equipped with a connecting piece with an adjusting groove and a fixing screw, so that the eccentricity and phase can be adjusted and locked on-site by sliding, thereby realizing independent and fine adjustment of the position of the upper and lower calendering rollers 13. The radial displacement and relative phase of the roller core can be finely adjusted without disassembling the drive shaft, thereby accurately correcting the roller gap and roller diameter concentricity, significantly improving the consistency of wire rod rolling thickness and surface quality. The eccentric connection and adjusting groove can tolerate certain installation errors, absorb radial / angular deviations, reduce the additional load and vibration of the coupling and bearings, and can be reliably locked after adjustment by fixing screws to ensure long-term transmission rigidity and torque transmission. Thirdly, the independent adjustment capability of the upper and lower sets of couplings facilitates compensation for different clearance requirements required by roller surface wear, thermal expansion, or process changes, improving equipment adaptability and production flexibility. It also facilitates rapid calibration and maintenance, shortens maintenance time, reduces downtime losses, and comprehensively improves the processing accuracy, reliability, and lifespan of the calendering unit.

[0023] The transmission synchronization mechanism 3 is equipped with a transmission box 34, and the gear is disposed inside the transmission box 34. The input shaft 31 is connected to the first output shaft 32, and the second output shaft 33 is located above the first output shaft 32 and is connected to the first output shaft 32 via the gear, so that the first output shaft 32 and the second output shaft 33 are driven synchronously. In this embodiment, the transmission synchronization mechanism 3 achieves rigid synchronous transmission of the upper and lower calendering rollers 13 by arranging gears inside the transmission box 34 and directly connecting the input shaft 31 to the first output shaft 32, and then having the first output shaft 32 drive the second output shaft 33 located above it via the gear, bringing about multiple technical benefits. First, ensure that the upper and lower calendering rolls maintain a strictly consistent 13-cycle speed to avoid slippage, stretching, or surface abrasion caused by speed differences, thereby improving the surface quality and dimensional consistency of the wire. Second, the gear drive provides timely and rigid torque transmission capabilities, can withstand large loads and distribute torque evenly, reduce unilateral overload and localized wear, and extend the life of the rolls, bearings, and couplings. Third, encapsulate the gears in the transmission box 34 for centralized lubrication and protection, reducing wear, noise, and environmental pollution, and improving equipment reliability and maintenance intervals.

[0024] The input shaft 31 is equipped with a pulley 311, and the output mechanism 4 is a drive motor, which is connected to the pulley 311 via a belt. In this embodiment, the belt drive structure has a certain degree of elasticity and buffering capacity, which can absorb impact and suppress vibration peaks during startup, shutdown, or sudden load changes, reducing the impact on the motor, bearings, couplings, and rollers, and improving the system's impact resistance and smooth operation. The belt drive can also provide overload protection to a certain extent. When the instantaneous load is too large, the belt is prone to limited slippage, protecting downstream mechanical components from damage and reducing the risk of failure and maintenance costs. The non-rigid connection between the belt and the pulley 311 has lower requirements for installation coaxiality and positional accuracy, which facilitates the arrangement of the motor and frame, reduces the difficulty of assembly and debugging, and makes maintenance and replacement easier, thus improving the maintainability of the equipment.

[0025] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
