Description
Technical field
The utility model relates to five metals processing instrument, specifically, is a kind of interior cold-forming expanding drill processing hole in valve seat.
Background technology
Along with the development of machinery industry, user is to the processing quality of product, process reliability, it is proposed higher requirement the delivery date of cutter etc., before hole machined is drilled in valve seat, first reaming is carried out, reaming is bored out on workpiece with expanding drill, the hole cast out or forge carries out expanding processing, reaming can correct the deflection of foramen primum axis to a certain extent, expanding drill is for expanding aperture, improve the cutter of processing quality, for final processing or the fraising in hole, processing in advance before mill hole, for the hole that specification of quality is not high, reaming also can be used as the final operation of hole machined. after valve seat is carried out reaming completion of processing, first reaming bit is first adopted to play a boring before drilling, then move back brill replacing drill bit to creep into, move back brill, more bit change process is loaded down with trivial details, and not only process velocity is slow, more workpiece is processed by bit change again, easily cause the center journal offset in aperture, cause the frequency of defect ware to increase, therefore for ensureing the quality of product, increase work efficiency, it is necessary to a kind of cutter that can reaming and boring be simultaneously carried out is to better meet the demand of industrial production.
