A cut to length machine is a class of industrial machinery used to slit metal coils into discrete, flat sheets of a specific, pre-set length. This process is a fundamental preparation stage in metalworking, creating the "blanks" that are later formed into final products. Shijiazhuang Faith Machinery Co., Ltd. produces these machines to help manufacturers efficiently convert bulk coil stock into manageable, ready-to-use sheets with high dimensional accuracy.
To understand how it works, it is helpful to follow the material's path through the machine. The process is linear and automated. It begins with the Decoiling Stage. A full metal coil is mounted onto a decoiler. As the machine operates, the decoiler rotates to pay out the coiled strip. A braking mechanism on the decoiler provides necessary tension to keep the coil tight and prevent loose, tangled material from entering the machine.
The strip then moves into the Flattening and Leveling Stage. Here, it passes through a leveler, which is a box-like unit containing multiple small-diameter rolls. These rolls are set at specific heights to deflect the metal slightly beyond its elastic limit in alternating directions. This action permanently removes the coil's memory, resulting in a perfectly flat sheet. Without this step, the final product would retain a curved shape, making it unsuitable for precision fabrication.
Once flattened, the sheet proceeds to the Feeding and Cutting Stage. A set of servo-controlled pinch rolls pulls the leveled material through the machine. An encoder, connected to one of the rolls, precisely measures the length of the material being fed. When the measured length matches the value entered into the control system, the servo motor stops, and the feeding halts. Instantly, a hydraulic shear or a guillotine cutter descends to make a clean, square cut across the width of the stationary sheet. The synchronization between the feed stop and the shear actuation is critical for length accuracy.
After the cut is complete, the Discharge and Stacking Stage begins. The cut sheet is conveyed away from the shear area. In basic systems, this may be a simple roller table. In more advanced setups, an automatic stacking system takes over. This stacker uses mechanisms like descending platforms or pneumatic arms to neatly pile the sheets into stacks, often with counters to keep track of production quantity. The entire operation is governed by a computerized control panel, allowing an operator to set parameters like sheet length, quantity, and production speed, making the process from Shijiazhuang Faith Machinery Co., Ltd. both repeatable and efficient for continuous industrial use.
