Sheet Metal Guillotine Shears Yawei manufactures in China
Metal cutting shear used is called a squaring shear, power shear, or guillotine. This machine may be foot powered, no more hand powered, or mechanically or hydraulically powered. It works from hydraulic holddown system holding the material with a ram before metal cutting action. A moving blade then comes down across a fixed blade to cutting the material. For larger sheet shears the moving blade may be set on an angle or "rocked" in order to cutting the material progressively from one side to the other; this angle is referred to as the shear blades angle. Setting the blade on an angle decreases the amount of force required, but increases the stroke. A 5 degree shear angle decreases the force by about 20%. The amount of energy used is still the same. The moving blade may also be inclined 0.5 to 2.5°, called the rake angle(http://www.ahycncs.net/hydraulic-shearing-machines/hydraulic-guillotine-shears/), to keep the material from becoming wedged between the blades. However, raking the blade compromises the squareness of the cutting edges, The machine consists of a cutting table, work-holding device, upper and lower blades, and a gauging device. The cutting machine table is the part of the machinery that the workpiece rests on while being cutting. The hold down device is used to hold the metal material in place and keep it from moving or buckling while under cutting action. The upper and lower blades are the piece of machinery that actually do the cutting action, while the gauging device is used to ensure that the workpiece is being cut where it is supposed to be, which with mm or inch.
