Description

Technical Field

[0001] The present invention relates to the technical field of steel wire production equipment, and in particular to a bridge steel wire production positioning device. Background Art

[0002] In modern bridge construction, steel wire, a key load-bearing material, plays a crucial role in the safety and stability of bridges. Wire positioning is an essential step in the production of bridge wire. Accurate positioning ensures the regularity and consistency of the wire during subsequent processing, weaving, and finished product formation, thereby improving the overall quality of the wire. However, there are many problems with the existing bridge steel wire production positioning technology. On the one hand, the traditional positioning device structure is relatively simple, and most of them use a single guide roller or limiting structure, which makes it difficult to perform all-round, high-precision positioning and calibration of the steel wire, resulting in the steel wire being easily offset, entangled, and other phenomena during the production process, seriously affecting the production quality and efficiency of the steel wire. On the other hand, the existing positioning device has a low degree of automation and requires a lot of manual operation to adjust and monitor the positioning status of the steel wire. This not only increases labor costs, but also makes it difficult to ensure the accuracy and stability of positioning, and cannot meet the needs of modern bridge construction for high-quality, large-scale steel wire production. In addition, some positioning devices lack effective gathering measures in the steel wire aggregation link, which makes it impossible for multiple steel wires to fit tightly during aggregation, affecting subsequent processing and use performance. Therefore, developing a bridge steel wire production positioning device with a reasonable and simple structure, low production cost, easy installation and the ability to achieve high-precision and automated positioning has become the key to solving current industry problems and improving the level of bridge steel wire production.

[0033] The usage status of the present invention is as follows: the present invention has a reasonable and simple structure, low production cost and easy installation. When producing bridge steel wire, first, the corresponding reel 14 is sleeved on the outside of the corresponding connecting shaft 13. At the beginning of production, the steel wire is unwound from the reel 14, preliminarily guided by the guide roller 15 on the left side of the installation cavity 12, and smoothly transported to the outer shell 2. After the steel wire enters the outer shell 2, it will pass through several staggered centering positioning mechanisms 3 in turn. Taking one of the centering positioning mechanisms 3 as an example, under the action of the centering positioning mechanism 32, the motor 3251 is started, and its output shaft drives the upper transmission shaft 3252 to rotate, and the lower transmission shaft 3252 rotates synchronously through the transmission pulley 3253 and the synchronous belt 1 3254. The two transmission shafts 3252 respectively drive the double-headed screw 1 324 and the double-headed screw 2 3210 to rotate, and use the thread transmission to make the slider 1 323 and the slider 2 329 move in the longitudinal guide groove 1 322 and the longitudinal guide groove 2 328, thereby driving the center The roller 326 adjusts its position to accurately center the steel wire. At the same time, the limiting guide block 33 and the limiting guide roller 34 can limit the upward and downward deviation of the steel wire to ensure that the steel wire moves forward stably in the center. After multiple calibrations of the centering positioning mechanism 3, the steel wire comes to the aggregation positioning mechanism 4, first passes through the aggregation guide roller 1 41 and the aggregation guide roller 2 42 for preliminary aggregation guidance, and then enters the automatic aggregation mechanism 43. When the steel wire enters the automatic aggregation mechanism 43, it will generate a lower card slot seat 434 and an upper card slot seat 435. The pressure causes the lower slide 433 and the upper slide 436 to overcome the elastic force of spring 1 432 and spring 2 437 and slide in the groove 431. The fixed pulley 438 and the synchronous belt 2 439 ensure that the lower slide 433 and the upper slide 436 move synchronously and in the center. The card roller 1 4351 and the card roller 2 4352 fit tightly to the steel wire, gathering multiple steel wires into a polygon. Finally, the gathered steel wires pass through the aggregate positioning hole 44, completing the entire positioning process and entering the subsequent production process in a regular state.

The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices. Therefore, the present invention will no longer explain the control method and wiring layout in detail.
