The spheronizing machine is a widely used cold forming equipment. According to the principle of three-point circle, the relative position and rotation of the deformation of the workpiece are constantly changed to obtain a predetermined shape of the workpiece. The product is widely used in boilers, shipbuilding, petroleum, wood, Metal and other machinery manufacturing. The common domestic work roll number and adjustment form are the standard mixed classification, symmetrical three-axis rounding machine, asymmetrical three-axis rounding machine, horizontally descending three-axis rounding machine, three-axis inclined round machine, three-axis rounding machine under the curve and Vertical downward three-axis rounding machine, etc. The work of the rounding machine refers to the ability of the workpiece in the cold state, according to the thickness and width of the workpiece, the maximum and minimum diameter yield limit of the drum capacity, and the cold rolling method at home and abroad. Cold rolling has high precision, simple operation process and low cost, but the quality of the workpiece (such as higher requirements is not allowed, cracks and other defects gap) organization uniformity.
