Description
Technical field
The utility model belongs to numerical control machining cutter technical field, and in particular to a kind of fuel assembly guide pipe end plug welding
Special-shaped slot shapes cutter.
Background technology
In the processing of CAP1400 fuel assembly guide pipes end plug welding special-shaped slot, the welding special-shaped slot of guide pipe end plug
Size characteristic is more and requirement on machining accuracy is high, and particularly bottom land Machining Arc does not allow more than R0.07mm, as shown in figure 1, should
Processed with 35 degree of point of a knife R0mm standard knife, time-consuming and cutter loss seriously needs frequent tool changing for processing.Based on above reason urgently
A kind of cutter need to be developed and solve this problem.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of special-shaped groove processing of fuel assembly guide pipe end plug welding
Forming tool, so as to improve the processing efficiency and cutting-tool's used life of product.
In order to realize this purpose, the utility model is adopted the technical scheme that：
A kind of fuel assembly guide pipe end plug welding special-shaped slot shapes cutter, and cutter body structure is 55 ° of rhombus
Excircle machining blade, the interior angle of diamond shaped insert is respectively 55 ° and 135 °；
Mating holes is opened up in the middle of cutter body, is connected knife bar with cutter by screw, mating holes；
The both sides cutting edge that the point of a knife part of diamond shaped insert is initial is all 22.5 °, and by machining deformation, both sides cutting edge is equal
For 30 degree.
Further, a kind of fuel assembly guide pipe end plug welding special-shaped slot as described above shapes cutter, rhombus
The length of side of blade is 11mm.
Further, a kind of fuel assembly guide pipe end plug welding special-shaped slot as described above shapes cutter, rhombus
The thickness of blade is 3.92mm.
Further, a kind of fuel assembly guide pipe end plug welding special-shaped slot as described above shapes cutter, coordinates
The diameter and screw fit in hole.
Further, a kind of fuel assembly guide pipe end plug welding special-shaped slot as described above shapes cutter, rhombus
The tool arc of blade is R0mm.
Further, a kind of fuel assembly guide pipe end plug welding special-shaped slot as described above shapes cutter, rhombus
The length of side of blade is 11mm, and thickness is 3.92mm, and tool arc is R0mm；The diameter and screw fit of mating holes.
The beneficial effect of technical solutions of the utility model is：
The cutter meets the mounting condition on CNC sliding headstock auto-lathe, and the product after processing fully meets drawing and technology bar
Part requirement.
Brief description of the drawings
Fig. 1 is the special-shaped slot structure schematic diagram of welding；
Fig. 2 is forming tool structural representation.
Embodiment
Technical solutions of the utility model are further elaborated below by the drawings and specific embodiments.
As shown in Fig. 2 a kind of fuel assembly guide pipe end plug welding special-shaped slot of the utility model shapes cutter, cutter
Agent structure is 55 ° of Excircle machining blades of rhombus, and the interior angle of diamond shaped insert is respectively 55 ° and 135 °；
Mating holes is opened up in the middle of cutter body, is connected knife bar with cutter by screw, mating holes；
The length of side of diamond shaped insert is 11mm, and thickness is 3.92mm, and tool arc is R0mm；The diameter of mating holes is matched somebody with somebody with screw
Close.
The both sides cutting edge that the point of a knife part of diamond shaped insert is initial is all 22.5 °, and by machining deformation, both sides cutting edge is equal
For 30 degree.
The cutter has been completed the production of more than 1000 part guide pipe end plugs, and product quality is stable, meets CAP1400 fuel
The processing mode of component guide pipe end plug simultaneously makes guide pipe end plug welding special-shaped slot meet drawing and technical requirements, so as to ensure production
The smoothly production of product.
