Specializing in the production rolling machine | Rolling Machine Technology | rolling machine price | Hebei Wanda rolling machine rolling machine is a versatile machine cold extrusion, rolling function in its cold rolling under pressure within the workpiece thread, ruled, denim rolling and other processing; straight, helical and helical spline gears rolling; straightening, necking, roll forming light and various rolling. Machines have safe and reliable electric - hydraulic actuator and control systems that enable each work cycle in manual, semi-automatic and automatic choice of three ways. Rolling the cold rolling process is an advanced non-cutting machining, can effectively improve the inner and surface quality of the workpiece, the processing of the radial compressive stress, can significantly improve the fatigue strength of the workpiece and the torsional strength, is a high efficiency, low consumption ideal processes. Processing principle in the cold rolling machine processing small modulus involute spline theory. L, R is a pair of the same parameters involute rolling wheel, rolling machines were installed in the two spindle, and in the transmission mechanism driving the same below the synchronous rotation. R wheel drive conducted by the cylinder radial feed motion, L wheel can be adjusted by adjusting the institutions with R round indentation in the surface of the workpiece P coincidence. P workpiece clamping with two center hole positioning, adjusting clamp the workpiece can move axially in force around the fixture can be viewed O point and parallel to the axis of the spindle swing a Φ angle in order to ensure that the workpiece during cold always keep up with two rolling wheels for rolling in a free state, while allowing workpiece clamping. Rolling wheel structure, size, shape and position tolerances and technical requirements refer rolling round and cylindrical measuring gear formulation, rolling wheel normal length or cross bars from M by spline gear ministry data calculation, the required material could Cr12MoV (hardness 59 ~ 62HRC). Rolling machine is divided into categories: two-axis and triaxial rolling machine rolling machine. 1, two-axis rolling machine in the metal construction, auto parts, transportation power, standard parts production, etc. have a strong advantage; 2, three-axis pipe thread rolling machine processing industry, such as triangular support to ensure roundness , concentricity and perpendicularity.
