Description

Technical Field

[0001] The present application relates to the technical field of wire coil production, and in particular to a rewinding trolley and a control method thereof. Background Art

[0002] Wire rod is a widely used round steel product, which is usually delivered in the form of coils after production. Cutting the ends of the wire rod is a crucial step in coil production. However, due to various factors, such as the installation position of the spinning head, vibration, and overspeed setting of the spinning machine, the ends of the wire coils often have problems such as irregular size and poor mechanical properties. These problems not only affect the overall quality of the product, but also cause troubles in subsequent processing and use. Therefore, in the coil production process, the ends of the wire coils need to be cut to ensure the quality and performance of the product.

[0003] In the production process of coiled wire, the wire is usually hung and fixed with a C-hook after being drawn, wound and other processes; when the head of the wire is cut off, the tail is on the inner side of the C-hook, and it is difficult for the operator to directly observe its position and status, which increases the difficulty of the trimming operation; the structure of the C-hook also limits the operator's activity space, making it difficult for them to perform effective trimming operations. How to achieve efficient and accurate trimming of the coil on the C-hook has become a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0004] The device provides a rewinding trolley and a control method, and the specific implementation methods are as follows:

[0006] A rewinding track and a rewinding trolley slidably arranged on the rewinding track, a pair of C-shaped hooks are arranged above the rewinding track along its length direction, and the opening directions of the two C-shaped hooks are opposite;

[0007] The rewinding trolley is composed of a rewinding member and a traveling body slidingly arranged on the rewinding track. The rewinding member is used to plug and transfer the coil on the C-shaped hook, and a lifting component for switching the supporting point of the coil is provided between the rewinding member and the traveling body.

[0008] The side of the rewinding piece is arranged as a concave structure which is staggered with the C-shaped hook, and the tail of the coiled end on the first C-shaped hook is cut. The rewinding piece transfers the coil on the first C-shaped hook to the second C-shaped hook by translation and lifting, and the head of the other end is cut on the second C-shaped hook.

[0009] Based on the above technical solution, two C-shaped hooks are used, and the opening directions of the two C-shaped hooks are set to be opposite to each other, thereby forming a complementary and functionally synergistic structure, which is used for support when trimming the head and tail of the coil respectively; it can realize smooth and precise translation and lifting operations of the rewinding piece, and the coil carried by the C-shaped hook can be smoothly rewound and transported, and the whole process is smooth and efficient; it also greatly facilitates the process of separately cutting the head and tail of the coil, which not only improves work efficiency, but also significantly enhances the convenience and flexibility of operation.

[0020] Based on the above technical solution, by adding a pressure sensor, it is not only possible to accurately determine whether the moving vehicle body has reached the predetermined position, but also to further realize intelligent judgment on whether the head of the lifting rod has accurately reached the coil lifting position on this basis; thereby greatly improving the accuracy and reliability of the lifting component operation, ensuring error-free execution at each key operation node.
