The workflow of a shearing machine typically includes the following key steps:
Sheet Metal Positioning: First, the metal sheet to be cut is placed on the shearing machine's worktable and secured by a positioning device to ensure it does not move or shift during the cutting process. This step is crucial for ensuring cutting accuracy.
Pressure Device Activation: After the sheet metal is positioned, the shearing machine's pressure device activates, pressing the sheet metal firmly against the worktable to prevent deformation or warping during cutting. The pressure device is usually hydraulically or mechanically driven, providing sufficient pressure to ensure sheet metal stability.
Blade Descending: Next, the shearing machine's blade begins to descend under the drive system. The drive system can be hydraulic or mechanical, depending on the type and design of the shearing machine. Hydraulic drive systems offer advantages such as smooth transmission, high power, and ease of control, and are therefore widely used in large shearing machines.
Sheet Metal Cutting: When the blade descends and contacts the sheet metal, cutting force is applied. As the blade continues its descent, the cutting force gradually increases until the sheet material is completely severed. During the cutting process, the shape and angle of the blade significantly affect the cutting result. Generally, blades are designed with sharp cutting edges and appropriate angles to ensure smooth and precise cutting.
Blade Ascent and Sheet Material Removal: After cutting, the blade will ascend under the drive system, returning to its initial position. At this point, the operator can remove the cut sheet material from the worktable for further processing or handling.
