Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel strand processing technology, and in particular to a wire drawing die fixing device for steel strand. Background Technology
[0002] In the production of steel strand, the wire drawing die fixing device is a key piece of equipment to ensure the quality of wire forming. Traditional fixing methods mostly use rigid clamping structures, which easily lead to the accumulation of debris on the contact surface between the die and the steel strand due to long-term friction, resulting in die hole blockage and scratches on the wire surface. At the same time, the fixing device lacks dynamic adjustment function, making it difficult to adapt to the processing requirements of steel strands of different specifications, affecting production efficiency and product consistency.
[0003] Existing application number CN202223495979.3 proposes a wire drawing die fixing device for steel strand, including a fixing block and a cover block. The upper end of the fixing block and the lower end of the cover block are provided with arc-shaped grooves, and the wire drawing die is fixed by the two arc-shaped grooves. A locking block is provided on each side of the lower end of the cover block, and a beveled flange is provided on one side of the lower end of each locking block. A locking hole is provided on each side of the upper end of the fixing block, and the locking block on the corresponding side cooperates with the locking hole. In use, the locking block is inserted into the lock hole. The inclined flange at the lower end of the locking block presses against the insert, causing the insert to move into the sliding groove, thus inserting the locking block into the lock hole. Once in place, the insert automatically resets under the action of the third spring, self-locking the inclined flange and preventing the locking block from coming out of the lock hole. However, the existing technology has a complex locking operation and requires high precision in the fit between the locking block and the lock hole, which can easily lead to installation difficulties. Furthermore, changing the mold is time-consuming and labor-intensive, affecting production efficiency. During processing, the product is prone to debris and dust, which can easily cause malfunctions in later use and reduce its service life. Utility Model Content
