Rolling material unwinding feeding, stamping automatic processing, material rack
Coil unwinding is the first process in stamping automated production and processing. In the process of unwinding and feeding of steel coils, heavy-duty material racks are used, and the gap-type feeding is sent when the time is stopped.
However, when the thickness of the material is thick and the elasticity is large, when the ordinary heavy-duty material frame is used, the steel strip is easy to be loosened, the working speed of the subsequent machine is not synchronized, and the negative feeding is defective, which affects the entire stamping production line. Efficiency, while bringing security risks.
In operation, the steel coil is placed on the heavy-duty material support tile, and A-shaped iron is placed on both sides of the support tile to position the steel coil.
The motor drives the tray to rotate, so that the steel strip is actively fed. When the steel strip is used on the subsequent leveler or feeder, the feeding speed of the steel strip is greater than the working speed of the leveling machine or the feeder.
Since the pressure roller is always pressed against the steel coil on the tray of the tray under the action of the pressing device with the cylinder, the sag of the steel strip is lowered, the sensing rod is swung, and the upper limit of the driving switch is driven by the impact of the bump. Bit, the motor is stopped, and the steel strip is unwinded.
When the steel strip continues to move forward after being leveled on the subsequent leveling machine, the sag of the steel strip rises, the sensing rod moves up, and the lower limit of the driving switch is driven by the impact block of the impact block, so that the motor rotates and drives the tray to rotate. The steel strip continues to feed.
The heavy-duty material frame with the pressing arm is used to control the unwinding feeding of the material roll by using the pressing wheel and the sensing rod at the same time. The design is exquisite and beautiful, the structure is reasonable and durable, and the pressing wheel is always pressed during the unwinding and feeding process of the steel strip. On the steel strip, the phenomenon of loose material in the steel strip is completely avoided.
The induction rod oscillates with the speed of the steel belt conveying, and controls the motor to start and stop by the bump block, thereby realizing the positive feeding of the steel strip, ensuring the synchronization with the entire stamping production line, thereby solving the problem caused by the negative feeding. Material scrapping phenomenon.
Greatly improve the efficiency of the entire stamping line, ensuring reliability and safety during the unwinding process.
