Description

Cold rolling device is used in aluminum alloy production

Technical Field

The invention relates to the technical field of aluminum production equipment, in particular to a cold rolling device for aluminum alloy production.

Background

In the early production of aluminum alloy products, it is essentially unavoidable to undergo a cold rolling process, to strengthen the strength and hardness of the strip by cold work hardening, and to obtain the desired thickness of the strip. Before the rolling starts, the currently used cold rolling mill needs to send the end part of the strip from the feeding end to the discharging end, and the end part of the strip is fixed on the rolling mechanism before the rolling; when the residual material on the discharging mechanism of the feeding end is insufficient, the residual material needs to be sheared off. This results in waste of material in the region of the length of the cold rolling mill at each of the ends and ends of each roll of strip, greatly increasing production costs.

In order to solve the technical problems, the Chinese patent with the authority of the publication No. CN112404127B discloses a cold rolling mill and a cold rolling process of a steel belt, wherein the rolling effect of the starting end of the steel belt to be rolled can be ensured by pulling the steel belt to be rolled through a belt blank to move, the problem that the cold rolling effect is poor and even the service life of a cold rolling mechanism is influenced due to the fact that the traction is absent at the initial end of the steel belt to be rolled is avoided, the cold rolling effect of the starting end of the steel belt to be rolled is ensured, and the service life of the cold rolling mechanism is prolonged.

However, in the actual use process, the strip blank and the strip to be rolled need to be welded before rolling, the weld joint is too large and protrudes out of the surface of the steel strip, the surface of the steel strip can be damaged in the rolling process, and particularly, welding slag is adhered to a rolling roller, so that the continuous adverse effect can be caused on the subsequent rolling of the steel strip. While too small a weld can result in unstable connections, the welding operation is difficult, and higher requirements are placed on welding equipment and welding techniques.

The end of the strip is then passed between the two rolls 62, between the two blowing plates 73, and is sucked and fixed from the upper surface of the strip by the suction cup 83, by passing through the strip end in this order between the two rolls 62, the rectangular extrusion frame 74, the rectangular liquid absorbent 72, the rectangular frame 71, the lower part of the suction plate 81. The cold rolling mechanism 6 is started to enable the two rollers 62 to rotate and roll the strip, meanwhile, the discharging suction plate 81 drives the end part of the strip to approach the rolling mechanism 9 along the length direction of the frame 01, and the strip passing through the rollers 62 is rolled in the process that the discharging suction plate 81 pulls the end part of the strip.

When a part of the end of the strip extends out of one side of the material pressing roller 92 away from the winding shaft 91, the discharging fan 84 is turned off, the material pressing roller 92 is driven to slide downwards, the strip is pressed downwards to be bent to be attached to the surface of the winding shaft 91, and the strip can be absorbed and wound by the winding shaft 91. When the winding shaft 91 winds up the part of the strip with the end part not rolled and with poor rolling quality, the cutting knife 93 is driven to close to the winding shaft 91 to cut off the strip, the part of the strip with the end part not rolled and with poor rolling quality is cut off, the strip with good rolling quality is wound up by the winding shaft 91, and the discharging suction plate 81 is reset.

When the aluminum coil allowance on the discharging mechanism 1 is insufficient, the communication feedback control electromagnet 26 of the meter 121 is powered off, the clamping plate 25 is driven to move upwards under the action of the tension spring 252, and the clamping plate 25 is used for applying certain pressure to the lower surface of the strip to press the strip. The tail end portion of the strip is then sucked and held from the upper surface of the strip by means of the feed suction cups 33, and then the whole of the feed suction plate 31 is slid along the stand 01 to approach the cold rolling mechanism 6. When the tail end of the strip is close to the cold rolling mechanism 6, the discharging suction plate 81 works, the discharging suction plate 83 fixes the tail end of the strip, the feeding suction plate 33 stops working and resets, and the whole discharging suction plate 81 slides along the frame 01 to be close to the rolling mechanism 9, so that the tail end part of the strip is smoothly conveyed to the rolling mechanism 9.
