After detection, the surface roughness Ra of the repaired pressure-bearing surface is 3.2, the planeness (<) is 0.03, and the parallelism with the end surface of the extrusion beam (<) is 0.05.
Stopping working after processing:
After the processing is finished, the processing amount of the pressure-bearing end face is confirmed by rechecking to be 8.05mm, and file records are made. The power is cut off, the power line is removed, and the device is removed from the extrusion movable beam. And storing the product in a specified special area for relevant maintenance and preservation.
And (3) extruding the movable beam to restore the reference function:
and selecting and installing the thickness of the high-strength transition pressure-bearing gasket to be 8.00+/-0.03 according to the machining quantity, so as to compensate the machining cutting quantity and restore the original design size and precision. And installing qualified extrusion rods, perforating needles and related parts, and recovering the structural integrity of the extrusion movable beam.
The static and dynamic relative position precision of the extruder is comprehensively detected, the extrusion movable beam, the extrusion cylinder shell and the perforation movable beam are adjusted to be relevant, the levelness of the extrusion rod is 0, the coaxiality of the central line of the whole extruder is (as per) 0.1, 60 TUI 110 multiplied by 8 pipe products are produced in a test mode, the maximum wall thickness deviation is less than or equal to 4.6%, the product quality requirement is met, and the 40MN horizontal double-acting copper and copper alloy extruder resumes normal extrusion production work.
The special machining device adopts the working combination principle of revolution and rotation, can realize the plane of a special mechanical structure, does not disintegrate equipment, and has the advantages of multi-angle deformation repair, high repair speed and low cost.
