A kind of aluminum double fork arm steering knuckle lower swing arm inverted taper hole processing method and device, adopt drill bit, ball head milling cutter, dovetail milling cutter, single blade reverse scraper, after drilling in closing end, minimum radius allowance is controlled at 0.3mm, ball head milling cutter is according to three-dimensional solid cone spiral side milling wide mouth end, dovetail milling cutter is according to layered way and is carried out semi-finishing and is connected with wide mouth end, after processing, the allowance is controlled as 0.05mm, finally utilize single blade reverse scraper and do finishing, the order is first circle arc feed and retreat tool and do circular interpolation processing, after processing, the allowance is 0.01mm, second circle is also arc feed, after removing the remaining allowance, do third circle arc interpolation finishing tool processing without retreat tool, after processing, arc retreat tool, then tool returns to center position according to the calculation result spindle back direction and is pulled back to finish taper surface, without cutting allowance, simply with finishing tool to finish processing, to reach the purpose of improving surface quality.Thus can replace expensive angle head and realize stable and efficient processing.

This invention discloses a solid cone eliminator device and its preparation method for water hammer in the condensate downcomer of an air-cooled island. The device includes an outer cylinder, a solid cone disposed inside the outer cylinder, a support plate, and a stop block. The outer cylinder is connected in series within the condensate downcomer of the air-cooled island. The solid cone is fixed inside the outer cylinder by the support plate, with its tip facing the direction of condensate flow. A guide hole is provided on the side wall of the solid cone, located slightly above the bottom of the cone, with the borehole axis parallel to the center line of the cone and inclined outward at an angle α. The stop block is welded between the inner wall of the outer cylinder and the support plate to reinforce the support structure. This invention effectively disrupts the conditions for water hammer and surge formation, ensuring long-term safe and stable operation of the system. It addresses the problem of water hammer shock waves in the condensate downcomer of an air-cooled island induced by complex and variable environmental conditions in winter.
