Technical Field
The utility model relates to a cutter technical field specifically says so, is a brill reamer of processing HT300 pump body hole.
Background
HT300 is pearlite gray cast iron, has high strength and good wear resistance, and is used for important castings in machine manufacturing, such as lathe bed guide rails, lathes, punches, lathe beds with larger stress, main spindle box gears and the like; it can also be used as high-pressure oil cylinder, pump body, valve body, etc. and parts for upsetting die, cold-punching die and surface quenching. To the pump body that HT300 made, utilize current cutter to carry out hole machining, there is the chip removal unsmooth, problem that part finish degree is out of tolerance, current cutter function singleness moreover, pump body hole machining needs to adopt many varieties cutter to accomplish, changes the cutter every time and all needs to carry out the tool setting, and tool changing tool setting occupation time is longer, adopts the processing that many cutters are used for a work piece, and machining efficiency is low, and is with higher costs.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a processing HT300 pump body hole bore reamer. The drilling and reaming machine integrates drilling and reaming, can realize rough machining and finish machining of inner holes of workpieces, and ensures the surface quality and roughness of tools.
The technical scheme is as follows: in order to achieve the above object, the utility model provides a processing HT300 pump body hole bore reamer, including cutting part and stalk portion, the front end of cutting part forms the drill point, is equipped with the main cutting edge on the drill point, and the back of a knife blade extends to the afterbody of cutting part from the spiral of main cutting edge department, and the smoothing sword sets up on the back of a knife blade, the both sides of the back of a knife blade are equipped with main chip groove and vice chip groove respectively, and main chip groove and vice chip groove extend from the afterbody spiral of drill point to cutting part.
Further, the groove length of the main chip discharge groove is larger than that of the auxiliary chip discharge groove.
Further, the vertex angle of the drill tip is 158-160 degrees
Furthermore, the included angle formed by the main cutting edge and the horizontal central axis is 70-72 degrees.
