The axis of Special scraper knife body 3 is passed through in one side, and position corresponding with square groove 3-1 is additionally provided at least two on Special scraper knife body 3
Blade 4 is mounted and fixed in corresponding square groove 3-1 by a screw hole 3-2 by the fastener 2 across the screw hole 3-2.
By designing a kind of tube sheet heat exchanger tube hole welding groove process tool in present embodiment, the melting welding ring can processed
When shape slot, trough size constancy, cutter head stress form will not change, but can change blade 4 and its mode that is loaded, in turn
Achieve the purpose that optimize cutter to improve work efficiency, the shortening production cycle reduces manufacturing cost.Due to annular groove and plate hole
It with concentricity requirement, therefore needs to design in Special scraper knife body front end leading to positioning sleeve 1, and uses brake pad in front end
Circle 5 is fixed, and guarantees that guide sleeve can be rotated, and has certain flexibility ratio.
Specific embodiment 2: embodiment is described with reference to Fig. 1, it is described it is leading to positioning sleeve 1 be made of brass before
Guide-localization set, the inner surface finish in view of plate hole are 1.6, need to select a kind of ratio in order to avoid scratching the inner surface in the hole
Tube sheet material is softer and has the metal material of certain wearability, therefore selects material of the brass as guide sleeve, and city
Brass recoverable on field, more economizes on resources, and reduces production cost, other steps and connection relationship and specific embodiment
