Several cutting processes are used to cut sheet metal. However, the shearing process by itself refers to a specific cutting process
that produces straight line cuts to separate a piece of sheet metal. In common, shearing is used for cutting a sheet parallel to an
existing edge which is held square, but angled cuts can be made as well. For this reason, shearing is mainly used to cut sheet
stock into smaller sizes in preparation for other processes.
The shearing process is performed on a shear machine, often called a squaring shear or power shear, that can be operated
manually by hand or by hydraulic, pneumatic, or electric power. A typical shear machine includes a table with support arms to hold
the sheet, stops or guides to secure the sheet, upper and lower straight-edge blades, and a gauging device to precisely position the
sheet. The sheet will be placed between the upper and lower blade, which are then forced together against the sheet, cutting the
material. In most cases, the lower blade keep still while the upper blade is forced downward. The upper blade is slightly offset from
the lower blade. Also,the upper blade is usually angled so that the cut progresses from one end to the other, thus reducing the
required force. The blades used in these machines typically have a square edge rather than a knife-edge and are available in different
materials, such as low alloy steel and high-carbon steel.
In addition, sheet metal prototyping provided by Rison Prototype have high accuracy, efficiency and durability to get your utmost
satisfaction. We also make perfect prototype details using surface treatments to serve our products for varied industries including
electronics, medical, automotive, new energy etc.
