Description

Technical Field

[0001] This utility model relates to the field of metal production and processing technology, specifically a straightening device for aluminum-clad steel wire with precise control over the reduction amount. Background Technology

[0002] The crimping process of aluminum-clad steel wire is a crucial step, ensuring the mechanical strength and electrical performance of the joint. The crimping process involves cleaning the joint area to remove dirt, grease, and other contaminants, ensuring a clean and smooth crimping surface. Different specifications of aluminum-clad steel wire require different crimping dies. Selecting appropriate crimping tools and dies is key to ensuring crimping quality. Using wire strippers, the insulation layer of the aluminum-clad steel wire is exposed. After stripping, it is checked for cracks and exposed copper wire. The aluminum-clad steel wire is crossed with the stripped copper wire using crimping pliers. The wound aluminum-clad steel wire is placed into the corresponding die, and the die is clamped with crimping pliers, applying sufficient pressure within a specified time. During the production of aluminum-clad steel wire, residual stress may be generated due to processes such as drawing, leading to instability, large fluctuations, and even wire breakage. Using a straightening device can effectively control the straightness of the steel wire.

[0003] Traditional straightening devices for precisely controlling the reduction amount of aluminum-clad steel wire typically employ mechanical reduction mechanisms, using manual adjustment of a screw or worm gear mechanism to control the reduction amount. However, this method suffers from several drawbacks. Manual adjustment makes precise control of the reduction amount difficult, easily leading to under-straightening or over-straightening, affecting product quality. Furthermore, each time a different specification of aluminum-clad steel wire is used, the reduction amount must be manually readjusted, resulting in cumbersome operation, low efficiency, and inability to integrate with other equipment on the production line, hindering automated production. Therefore, this paper proposes a straightening device for precisely controlling the reduction amount of aluminum-clad steel wire. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a straightening device that allows for precise control of the reduction amount of aluminum-clad steel wire, thereby solving the aforementioned technical problems of low adjustment accuracy, cumbersome operation, and low degree of automation.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a straightening device for precisely controlling the reduction amount of aluminum-clad steel wire, comprising:

[0008] The frame, and the outer frame seat set on the upper surface of the frame, and the PLC controller is mounted on the front of the frame, and the touch screen is connected above the PLC controller;

[0009] A servo motor is mounted on the upper surface of the outer frame, and a ball screw is added to the top of the inner cavity of the outer frame. The ball screw is coaxially connected to the servo motor, and a movable pressure block is sleeved on the surface of the ball screw.

[0010] The upper pressure roller is located below the movable pressure block and is slidably connected to the left and right sides of the inner wall of the outer frame. A lower pressure roller is added below the upper pressure roller and is connected to the left and right sides of the inner wall of the outer frame. A pressure sensor is installed on the upper surface of the upper pressure roller. The required pressing pressure value is set via a touchscreen. The PLC controller receives the signal from the pressure sensor and controls the servo motor based on the preset pressure value. The servo motor drives the ball screw to rotate on the outer frame, and the rotation of the ball screw can be adjusted. The ball screw drives the moving pressure block to move up and down, thereby causing the upper pressure roller to move downward on the outer frame. This, in conjunction with the lower pressure roller, achieves precise control of the pressing amount of the aluminum-clad steel wire. This device uses a servo motor and ball screw drive, combined with a pressure sensor and a built-in control system, to achieve precise control of the pressing amount, high adjustment accuracy, and improved product quality. The pressing pressure value can be set and adjusted via the touchscreen, making it easy to operate and highly efficient. It can also be linked with other equipment on the production line to achieve automated production with a high degree of automation. At the same time, this device has a simple structure, is easy to operate, and can effectively improve the accuracy and efficiency of straightening aluminum-clad steel wire, with broad application prospects.

[0011] Preferably, guide rollers are provided on both the left and right sides of the frame, and bearings are rotatably connected to both ends of the guide rollers. When the aluminum-clad steel wire can move along the surface of the guide rollers onto the frame for straightening, the aluminum-clad steel wire can drive the guide rollers to rotate on the bearings through friction. This avoids scraping between the surface of the aluminum-clad steel wire and the edge of the frame, thus protecting the surface quality of the aluminum-clad steel wire, reducing frictional resistance during the movement of the aluminum-clad steel wire, and extending the service life of the equipment.

[0012] Preferably, support legs are installed around the lower surface of the frame, and a drive motor is installed on the top of each support leg. The support legs provide support for the frame, while the drive motor drives the corresponding structure to rotate on the support legs and adjusts the direction of the corresponding structure.

[0013] Preferably, each of the support legs is rotatably connected to a threaded screw, and the threaded screw is coaxially connected to the drive motor. The drive motor drives the threaded screw to rotate on the support leg and adjusts the direction of rotation of the threaded screw.

[0014] Preferably, the outer surface of the threaded screw is fitted with a sliding block, and the left and right sides of the sliding block are slidably fitted against the inner wall of the support leg. The sliding block moves up and down along the inner wall of the support leg according to the rotation of the threaded screw.

[0015] Preferably, each sliding block has an external connecting rod mounted on its front side, and the external connecting rod is connected to the bottom of the bearing. The sliding block drives the guide roller to move up and down according to the usage conditions through the external connecting rod and the bearing. This not only accommodates aluminum-clad steel wires of different diameters within a certain range, but also facilitates the installation and maintenance of the equipment.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a straightening device for aluminum-clad steel wire with precise control over the reduction amount, which has the following advantages:

[0018] This straightening device for aluminum-clad steel wire with precise control over the pressing amount allows users to set the required pressing pressure value via a touchscreen. A PLC controller receives signals from a pressure sensor and controls the servo motor based on the preset pressure value. The servo motor drives a ball screw to rotate on the outer frame, and the rotation of the ball screw can be adjusted. The ball screw then moves a movable pressure block up and down, causing the upper pressure roller to move downwards on the outer frame. This, in conjunction with the lower pressure roller, achieves precise control over the pressing amount of the aluminum-clad steel wire. This device uses a servo motor and ball screw drive, combined with a pressure sensor and a built-in control system, to achieve precise control of the pressing amount, high adjustment accuracy, and improved product quality. The pressing pressure value can be set and adjusted via the touchscreen, making it easy to operate and highly efficient. It can also be linked with other equipment on the production line to achieve automated production, offering a high degree of automation. Furthermore, this device has a simple structure, is easy to operate, and effectively improves the accuracy and efficiency of aluminum-clad steel wire straightening, making it a promising solution for a wide range of applications.
