Description

Technical Field

[0001] This utility model relates to the field of metal rod processing technology, and in particular to a metal rod straightening device. Background Technology

[0002] Existing metal rod straightening equipment often suffers from unstable power transmission and low straightening accuracy. Some equipment uses a single drive source to drive the straightening wheel, which is prone to transmission slippage due to uneven load, affecting the stability of metal rod conveying. Furthermore, the straightening wheel spacing adjustment structure is complex, making it difficult to quickly adapt to metal rods of different diameters and reducing processing efficiency. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a metal rod straightening device.

[0004] This utility model proposes a metal rod straightening device, including a cabinet. A first driving device and a second driving device are symmetrically mounted on the top of the cabinet. A straightening device is installed in the middle of the first and second driving devices. The first and second driving devices jointly drive the metal rod in the straightening device to move, thereby straightening the metal rod. Both the first and second driving devices include a reducer mounted on the top of the cabinet. The reducer has several output ends, each connected to a first universal coupling. Each first universal coupling has a drive shaft connected inside, and each drive shaft has a second universal coupling at its end. The straightening device includes several lower and upper axles. The lower axles are connected to the drive shaft of the first driving device, and the upper axles are connected to the drive shaft of the second driving device. A lower straightening wheel and an upper straightening wheel are installed at adjacent ends of each lower and upper axle, and the metal rod passes through the interior of the lower and upper straightening wheels.

[0005] Furthermore, the top of the equipment cabinet is symmetrically equipped with a feeding alignment cylinder and a discharging alignment cylinder. The feeding alignment cylinder corresponds to the inlet of the straightening device, and the discharging alignment cylinder corresponds to the outlet of the straightening device. The metal rod enters from the inside of the feeding alignment cylinder and exits from the inside of the discharging alignment cylinder. The inner diameter of both the feeding alignment cylinder and the discharging alignment cylinder is larger than the outer diameter of the metal rod.

[0006] Furthermore, both the first and second drive devices include a motor installed inside the equipment cabinet, and the drive end of the motor is connected to the input end of the reducer via a transmission kit.

[0007] Furthermore, the transmission assembly includes a driving synchronous pulley mounted on the motor drive end, a driven synchronous pulley mounted on the reducer input end, and a synchronous belt connected to the outside of the driving and driven synchronous pulleys.

[0008] Furthermore, the lengths of several drive shafts increase progressively in the direction of movement of the metal rod.

[0009] Furthermore, the straightening device also includes a fixed base installed on the top of the equipment cabinet, and a lifting base is provided directly above the fixed base. The fixed base and the lifting base are connected by several columns.

[0010] Furthermore, the top of the column extends to the top of the lifting seat through a pre-drilled through hole, and a threaded groove is formed on the top of the column. The lower adjusting nut and the upper adjusting nut are connected to the outside of the threaded groove. The lower adjusting nut and the upper adjusting nut are located at the bottom and top of the lifting seat, respectively.

[0011] The beneficial effects of this utility model are as follows: By using a symmetrically arranged first and second drive device, coupled with a universal coupling and a transmission shaft with progressively adaptable length, stable power transmission is achieved, avoiding transmission slippage and uneven load, and ensuring the smooth conveying of the metal rod. At the same time, the straightening device, with the help of a lifting seat whose height can be adjusted by a nut, can quickly adjust the distance between the upper and lower straightening wheels to adapt to metal rods of different diameters. Combined with the precise guidance of the feeding and discharging alignment cylinders, the straightening accuracy and processing efficiency are effectively improved. Furthermore, the protective design of the equipment cabinet for internal components can reduce the impact of dust and impurities, extend the service life of the equipment, and reduce maintenance costs. The overall structure is compact and reasonable, taking into account both practicality and economy. Attached Figure Description

[0014] Reference Figure 1-5 This utility model proposes a metal rod straightening device, including a cabinet 1. A first drive device 2 and a second drive device 3 are symmetrically arranged at the top of the cabinet 1, jointly providing stable power for the conveying and straightening of the metal rod 7. Each drive device includes a motor 21 installed inside the cabinet 1. The motor 21 is a high-torque three-phase asynchronous motor, characterized by smooth start-up and controllable speed. Its output speed can be flexibly adjusted according to the material, diameter, and other parameters of the metal rod 7. The drive end of the motor 21 is connected to a reducer 22 located at the top of the cabinet 1. The input end transmits power through the transmission kit 26, which consists of a driving synchronous pulley 261, a driven synchronous pulley 262, and a synchronous belt 263. The driving synchronous pulley 261 is tightly mounted on the drive shaft of the motor 21, while the driven synchronous pulley 262 is fixedly connected to the input end of the reducer 22. The synchronous belt 263 is wrapped around the two synchronous pulleys and transmits power through tooth meshing. Compared with traditional belt drives, it can effectively avoid slippage and ensure the accuracy and efficiency of power transmission, so that the power of the motor 21 can be transmitted to the reducer 22 stably and without loss. The reducer 22 adopts a multi-output shaft structure, with several output ends of the same specification (these output ends can rotate synchronously and in the same direction through an internal gear set, which is a well-known technical feature and will not be described in detail here). Each output end is connected to a first universal coupling 23 via a flange. The first universal coupling 23 has good angle compensation capability, which can effectively offset the coaxiality deviation that may occur during the installation of the drive shaft 24 and avoid generating additional radial force during transmission. The other end of the first universal coupling 23 is fixedly connected to the drive shaft 24. Several drive shafts 24 are arranged in a metal-... The length of the rod 7 increases progressively in the direction of movement. This design is compatible with the distribution of the wheel axles in the straightening device 4, ensuring that each drive shaft 24 can be accurately connected to the corresponding lower wheel axle 41 or upper wheel axle 42. At the same time, it avoids spatial interference between drive shafts 24 due to their consistent length, ensuring the compactness and rationality of the transmission system. The other end of each drive shaft 24 is also connected to a second universal coupling 25. The function of the second universal coupling 25 is the same as that of the first universal coupling 23, further compensating for the installation deviation between the drive shaft 24 and the wheel axle, ensuring that the power can be smoothly transmitted to the straightening device 4. The straightening device 4, located between the first drive unit 2 and the second drive unit 3, consists of a lower wheel axle 41, an upper wheel axle 42, a lower straightening wheel 43, an upper straightening wheel 44, a fixed base 45, a lifting base 46, and columns 47. The fixed base 45 is bolted to the top of the equipment cabinet 1, serving as the bottom support structure of the straightening device 4. The lifting base 46 is arranged parallel to the fixed base 45 directly above it, and the two are connected by several evenly distributed columns 47. The columns 47 are welded to the fixed base 45 to ensure connection strength. The top of the column 47 passes through a pre-drilled hole in the lifting base 46. Extending upwards, the top of the column 47 is machined with a threaded groove 48. A lower adjusting nut 49 and an upper adjusting nut 410 are installed on the outside of the threaded groove 48. The lower adjusting nut 49 is set against the bottom of the lifting seat 46, while the upper adjusting nut 410 is located on the top of the lifting seat 46. By synchronously rotating the lower adjusting nut 49 and the upper adjusting nut 410 on the same column 47, the height position of the lifting seat 46 on the column 47 can be adjusted, thereby changing the distance between the upper wheel shaft 42 and the lower wheel shaft 41 to adapt to the straightening requirements of metal rods 7 with different diameter specifications, greatly improving the versatility of the equipment.

[0015] The lower axle 41 is horizontally mounted on the fixed seat 45 via bearing housing 411, and the upper axle 42 is similarly mounted on the lifting seat 46 via bearing housing 411. The axes of the lower axle 41 and the upper axle 42 are parallel to each other, and one end of each lower axle 41 is connected to the drive shaft 24 of the first drive device 2 via a second universal coupling 25. One end of each upper axle 42 is connected to the drive shaft 24 of the second drive device 3 via a second universal coupling 25. At adjacent ends of each lower axle 41 and upper axle 42, a lower straightening wheel 43 and an upper straightening wheel 44 are respectively installed. The rims of the lower straightening wheel 43 and the upper straightening wheel 44 are machined with... An arc-shaped groove that fits the outer circle of the metal rod 7 and the two grooves are aligned vertically to form a conveying and straightening channel for the metal rod 7. When the first drive device 2 and the second drive device 3 are started, power is transmitted to the lower wheel shaft 41 and the upper wheel shaft 42 through the transmission shaft 24 and the second universal coupling 25, respectively, driving the lower straightening wheel 43 and the upper straightening wheel 44 to rotate synchronously in the same direction. The metal rod 7 passes through the channel between the upper and lower straightening wheels and moves forward under the friction of the rotating straightening wheels. At the same time, the upper and lower straightening wheels apply uniform radial pressure to the metal rod 7, gradually correcting the bent parts of the metal rod 7 and realizing the straightening process. To ensure the metal rod 7 enters the straightening channel accurately and avoids straightening deviation or equipment malfunction due to feed offset, a feed alignment cylinder 5 and a discharge alignment cylinder 6 are symmetrically installed at the top of the equipment cabinet 1. The feed alignment cylinder 5 is located in front of the inlet of the straightening device 4, and its axis coincides with the center line of the straightening channel. Before entering the straightening device 4, the metal rod 7 passes through the feed alignment cylinder 5. The feed alignment cylinder 5 guides and positions the metal rod 7, ensuring that it enters between the upper and lower straightening rollers in the correct posture. The material alignment cylinder 6 is located behind the outlet of the straightening device 4 and is also aligned with the center line of the straightening channel. The straightened metal rod 7 passes through the discharge alignment cylinder 6. The discharge alignment cylinder 5 can prevent the metal rod 7 from shifting due to inertia after straightening, ensuring the stability of the discharge direction. In addition, the inner diameter of both the feed alignment cylinder 5 and the discharge alignment cylinder 6 is slightly larger than the outer diameter of the metal rod 7. While ensuring the alignment effect, it avoids excessive friction with the surface of the metal rod 7 and causes scratches, thus protecting the surface quality of the metal rod 7.

[0016] In actual operation, the operator can adjust the distance between the upper and lower straightening rollers by adjusting the height of the lifting seat 46 according to the diameter of the metal rod 7 to be straightened. Then, one end of the metal rod 7 is inserted into the feeding alignment cylinder 5, the equipment is started, and the first driving device 2 and the second driving device 3 drive the upper and lower straightening rollers to rotate. Under the driving and squeezing action of the straightening rollers, the metal rod 7 moves forward while completing the straightening, and finally passes out from the discharge alignment cylinder 6 to obtain a straight metal rod 7. The whole equipment has a compact structure, is easy to operate, has high straightening efficiency and good effect, and can meet the straightening processing needs of metal rods of different specifications.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
