AN APPARATUS FOR UNIFORM END CUTTING OPERATION FOR SUPERHEATER AND REHEATER PANELS IN HIGH PRESSURE BOILERS PRIOR TO EDGE PREPARATION

摘要

The invention relates to an apparatus for end cutting of tubes delivered from a furnace after stress relieving and prior to edge preparation to produce panels of superheaters and reheaters in high pressure boilers, comprising a base plate (05) mountable on the panel top with at least two C� clamps wherein linear motion guide is fitted with bearing block for longitidunal motion along the length of the the base plate; an angle base plate (03) mounted on the top of the bearing block to hold a bracket assembly (02) which in turn attached to a panel end cutting machine by a solid rod (06);the liner motion guide (04) positioned on the base plate (05) by means of atleast one pair of grub screws (08); the angle plate (03) fixed by means of a second pair of grub screws (08) on the top of the bearing block (04); the holding bracket assembly (02) including the solid rod (06) attached to the panel end cutting machine (01); wherein a handle provided on the cutting machine (01), and wherein a hand feeding of a cutting wheel performs the cutting operation without much effort and at a less time in a single setting for one end, and wherein the operation is repeated for the other end of the panel.
