Through multiple rolling deformations, the steel pipes can achieve the required specifications and precision. This processing method can significantly improve the dimensional accuracy and surface quality of steel pipes, meeting the high requirements of precision mechanical parts for size and shape.
[0003] The "Automatic Cutting Equipment for Precision Rolled Steel Pipes" disclosed in application number "202223590758.4" includes a base at the bottom, a support near one end of the base, a cylinder mounted on the top of one end of the support, and a cutting wheel for cutting mounted on the bottom of the cylinder. It also includes a feeding assembly, a precision rolled steel pipe, and a positioning assembly. Several feeding assemblies are mounted on the top of the base, and the precision rolled steel pipe is placed on each feeding assembly. A positioning assembly is located on the other side of the top of the base. The positioning assembly includes a housing, a baffle, and a touch switch. The housing is fixed to the base, and a lead screw is mounted in the middle of the housing. Two guide columns are symmetrically fixed on both sides of the lead screw. Moving blocks are mounted on the lead screw and guide columns. A positioning motor is mounted on one end of the lead screw, and a wire hole is opened on the moving block corresponding to the position of the lead screw. This utility model has a novel structure and ingenious design, facilitating the positioning and cutting of precision rolled steel pipes.
