The basic form of the deformed steel bar

The basic form of electricity deformed steel bar have? Power steel bar suffered a variety of external forces, thus deformed steel bar member general will have a more complex form. But to sum up, deformed steel bar can be divided into the following four basic forms.
First, when the power axial tension or axial compression steel rod when straight steel rod by a pair of equal and opposite directions, external force action line and heavy steel pole member axis table, the main deformation is elongated or shortened lengths. The former is called axial tension, the latter known as axial compression. Such as a simple truss steel rod member, their deformation, deformation belong to this basic form.
Second, the power cut when the straight steel rod steel bar by a pair of equal and opposite directions, vertical and in close proximity when the external force, which is adjacent to the main line of action of the deformation axis of inertia with steel rod cross-section along the direction of the external force relative error occurred This form is called dynamic shear deformation.
Third, the power to reverse when the straight steel rod steel bar by a pair of equal and opposite, both with the couple when acting surface perpendicular to the axis of the steering role of steel bar. Straight impeach any two of the cross section relative rotation about an axis, said such deformation form To reverse.

Fourth, the electricity when bent steel rod straight steel rod by a pair of equal size, steering the contrary, the role of the role when the couple faces the longitudinal plane of symmetry coincides steel bar, any two straight steel rod cross-section will be about perpendicular to the longitudinal plane of symmetry pumping relative rotation, the axis of the straight steel rod into a curve. This form is called bending deformation overcast

Our firm introduced whole set of good-sized numerical control hydraulic folding equipment(1280/16000) as well as equipped with a series of good-sized professional equipments of armor plate-flatted machine, lengthways cut machine, numerical control cut machine, auto-closed up machine, auto-arc-weld machine, hydraulic redressing straight machine, etc. The firm produces all sorts of conical, pyramidal, cylindrical steel poles with production range of dia 50mm-2250mm, thickness 1mm-25mm, once taking shape 16000mm long, and large-scale steel components. The firm also is equipped with a multicolor-spayed pipelining. At the meantime, for better service to the clients, our firm founded a branch com. The Yixing Jinlei Lighting Installation Com, which offers clients a succession of service from design to manufacture and fixing.
