Technical Field
[0001] This utility model belongs to the field of cold rolling mill technology, specifically relating to a tension adjustment device for high-speed aluminum strip thinning. Background Technology
[0002] The tension adjustment device for high-speed aluminum strip thinning is one of the most crucial pieces of equipment in the aluminum strip production process. It is primarily used to precisely adjust the thinning of the aluminum strip during production and to ensure thickness uniformity and quality stability through tension control. This device typically includes a support base, adjustment mechanism, drive system, and other components, achieving precise thinning and tension adjustment of the aluminum strip through a complex mechanical structure and control system.
[0003] The most commonly used equipment in the aluminum strip rolling process is the cold rolling mill. The core components of this equipment mainly include the load-bearing rolls and the work rolls. Below the load-bearing rolls, a wedge block and a corresponding screw adjustment mechanism are cleverly installed. By precisely operating the screw, the position of the wedge block can be finely adjusted, thereby changing the inclination angle and height of its contact surface. This change directly affects the distance between the load-bearing rolls and the work rolls, thus achieving precise adjustment of the aluminum strip rolling thickness.
[0004] When cold rolling aluminum strip, the roll gap setting is crucial. If the roll gap is too small, the aluminum strip will be subjected to excessive pressure as it passes through the rolls. This can not only damage the surface of the aluminum strip but also increase the internal stress, resulting in excessive tension during rolling. Excessive tension not only affects the quality of the finished aluminum strip, causing problems such as edge cracking and uneven thickness, but can also place excessive load on the cold rolling mill's components, shortening the equipment's lifespan.
[0005] However, if the roll gap is set too large, the pressure on the aluminum strip as it passes through the rolls will be insufficient to achieve the desired thinning effect, resulting in the aluminum strip thickness failing to meet production requirements. Therefore, to ensure that the aluminum strip achieves the desired thickness during rolling without experiencing excessive pressure and tension, precise roll gap adjustment is necessary based on the material and thickness of the aluminum strip.
