The utility model content
The utility model technical issues that need to address provide a kind of flat thread cutter, it mainly is to solve existing in prior technology screwer work in-process can produce interference with other cutter in workpiece, and sharpening partly can residual iron filings in working angles for screwer, are unfavorable for the technical problem of machining etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of flat thread cutter of the present utility model comprises hilt, it is characterized in that described hilt end is connected with cutting head, and the end face of smear metal head and vertical plane form vertical anterior angle α
1, vertical anterior angle α
1Be 12～16o; The upper surface of smear metal head and horizontal plane form vertical relief angle α
2, vertical relief angle α
2Be 6～8o; The upper surface of smear metal head is provided with working face, the outer surface arc transition of working face and hilt.Rotate by the step speed change numerically controlled lathe, drive the workpiece rotation, and drive little supporting plate simultaneously and do the cross cutting motion, to reach the purpose of processing plane screw thread.By the face length of a control smear metal upper surface, can avoid shake cutter phenomenon in the processing.Working face is inclined upwardly, the upper surface keeping parallelism of working face and smear metal head.By the sharpening width and the height dimension of cutting head, satisfy each serial product of processing.
As preferably, the end face of described cutting head is for trapezoidal, edge clearance angle β on the left of the outer surface in cutting head left side forms with vertical plane
1, left side edge clearance angle β
1Be 5～8o; The outer surface on cutting head right side and vertical plane form left side edge clearance angle β
2, right side edge clearance angle β
2Be 2～4o.By increasing left side edge clearance angle and right side edge clearance angle, cutter produces with workpiece and interferes in avoiding processing, and helps machining.
As preferably, two sides and the horizontal line of the bottom surface of described cutting head form left side sword auxiliary angle γ respectively
1With right side sword auxiliary angle γ
2, left side sword auxiliary angle γ
1Be 1～1.5o, right side sword auxiliary angle γ
2Be 1～1.5o.Sword auxiliary angle by the sharpening both sides and vertical relief angle are in order to reach the requirement of smooth eliminating iron filings.
As preferably, the two ends of described hilt respectively are connected with a cutting head, and the upper surface of two cutting head is towards on the contrary.Cut interchangeable other end, first head wearing and tearing back and use, can save cost.
Therefore, the utlity model has the screwer work in-process and in workpiece, can not produce and interfere, and screwer sharpening part in working angles can get rid of residual iron filings, characteristics such as the product quality of machining is higher, and is simple and reasonable for structure with other cutter.
