Problems solved by technology
The uncoiling of cold-rolled strip steel is an important part of the strip steel production process. If the uncoiler is not uncoiled smoothly, it will not only affect production efficiency, but may also affect product quality.
[0004] In the prior art, most of the steel strips are scooped up with a shovel (i.e. an uncoiler) so that they can smoothly enter the straightening machine for uncoiling. In the case of not being scooped up by the shovel plate, at this time, as the uncoiler continues to rotate, the steel strip gradually bends and arches, which not only fails to uncoil smoothly, but also causes the steel strip to bend and deform, thus affecting process efficiency and product quality. caused a certain impact

Embodiment
[0045] see figure 1 , the uncoiling control system of cold-rolled steel coils, including a pressure roller 2, a straightening combination scraper, a main control system and a reel 1 installed on the uncoiler, the correction combined scraper includes a hollow scraper 3 and a pressure strip 4, and the hollow scraper The plate 3 and the platen 4 are connected through the rotation of the electric shaft, and the hollow shovel plate 3 is provided with an uncoiling slideway 301, please refer to Figure 6, the lower edge of the uncoiling slide 301 near the notch of the pressure plate 4 is in a pointed shape, which is convenient for scooping up the coil head to realize uncoiling. The pressure plate 4 is located on the upper side of the uncoiling slide 301, and the lower end of the pressure plate 4 is fixed Connected with a back pressure air bag 5, the outer end of the pressure belt plate 4 is fixedly connected with an air intake pipe 6 with a valve, one end of the air intake pipe 6 run...

The invention discloses an uncoiling control method and an uncoiling control system for a cold-rolled steel coil, and belongs to the technical field of uncoiling of the cold-rolled steel coil. In the process of uncoiling abnormity of a steel belt head, a steel belt correction process can be automatically triggered through extrusion of a bent and arched steel belt on a back pressure air bag; on the one hand, sufficient gas is injected into the gas column, so that the gas column expands and extends linearly quickly, impacts the arched steel belt from inside to outside, vibrates and displaces, on the other hand, the rotation of the belt pressing plate drives the back-pressure gas bag to obliquely extrude the arched steel belt, the interaction force between the belt head and the edge of the uncoiling slide way is increased, and the belt head is prevented from falling off due to the double acting force. The strip head is promoted to smoothly break through blocking of the edge of the uncoiling slide way and be smoothly guided out along the uncoiling slide way, correction of the strip head of the steel strip is achieved, uncoiling faults of a cold-rolled steel coil are effectively reduced, and smooth uncoiling is achieved.
Description
technical field [0001] The present invention relates to the technical field of uncoiling of cold-rolled steel coils, and more specifically, relates to an uncoiling control method and an uncoiling control system of cold-rolled steel coils. Background technique [0002] Cold-rolled steel is made of hot-rolled steel coils as raw materials. After pickling to remove scale, cold rolling is carried out. The finished product is hard-rolled coils. The strength and hardness of hard-rolled coils increase due to cold hardening caused by continuous cold deformation. 1. The toughness and plasticity index will decrease, so the stamping performance will deteriorate, and it can only be used for parts with simple deformation. [0003] Uncoiler is one of the important equipment in the production process of cold rolled strip steel. In the strip steel cold rolling production line, fast production rhythm and smooth decoiling play an important role in the strip steel production efficiency and pro...
