The wire rolling machine is a multi-functional cold extrusion machine tool. The wire rolling machine can work within its rolling pressure range and roll the workpiece with thread, straight grain and twill in cold state; Rolling of spur, helical and helical spline gears; Straightening, reducing, rolling and various forming rolling. The machine has a safe and reliable electro-hydraulic execution and control system, which can select each working cycle in manual, semi-automatic and automatic modes.
Wire rolling cold rolling process is an advanced non cutting process, which can effectively improve the internal and surface quality of the workpiece. The radial compressive stress generated during processing can significantly improve the fatigue strength and torsional strength of the workpiece. It is an ideal process with high efficiency, energy saving and low consumption.
The principle of cold rolling small modulus involute spline on wire rolling machine. 50. R is a pair of involute rolling wheels with the same parameters, which are respectively installed on the two main shafts of the wire rolling machine and can rotate synchronously in the same direction driven by the transmission mechanism. The R wheel can be driven by the oil cylinder for radial feeding movement, and the L wheel can coincide with the indentation of the R wheel on the P surface of the workpiece through the adjustment of the adjustment mechanism. The workpiece P is positioned and clamped with two central holes. Adjusting the fixture can make the workpiece move axially. When stressed, it can swing one axis parallel to the machine tool spindle through o point on the fixture Φ Angle to ensure that the workpiece is always in a free rolling state with the two rolling wheels during the cold rolling process, and it is convenient to clamp the workpiece at the same time.
The structural dimension, form and position tolerance and technical requirements of the rolling wheel shall be formulated with reference to the wire rolling wheel and cylindrical measuring gear. The common normal length or cross bar Distance m of the rolling wheel shall be calculated according to the spline data in the gear work, and the required material can be Cr12MoV (hardness 59 ~ 62Hrc).
Steel bar rolling straight thread connection technology is applicable to industrial and civil buildings. It is required to give full play to the connection construction of rigid, inclined and horizontal steel bars in important parts of the structure where the strength and ductility of steel bars are required. It has simple and fast process, can be prepared, no open fire operation, no environmental pollution, no hidden danger of explosion and fire, safe and reliable, can be constructed all day, and saves a lot of steel and energy. Only use a wrench to connect the reinforcement, and each reinforcement joint is about one minute. The construction period of the structure is shortened and the industrialized and civilized construction is realized.
