Abstract

The utility model relates to a cutting tool in the field of machinery manufacture, in particular to an outer circular knife for manufacturing fire hydrant spouts. The outer circular knife for manufacturing the fire hydrant spouts comprises a cutter handle and a cutter head arranged on one end of the cutter handle, wherein a first cutter body is arranged on the lower end surface of the cutter head, the lower end surface of the cutter head is further provided with a second cutter body for chamfering manufactured workpieces, thereby, workpieces are shaped in one time, cutters can be used extremely conveniently through arranging a second cutter body for chamfering on the cutter head, the time for replacing cutters can be saved, and the working efficiency can be improved.

Description

The outer dise knife of processing fire hydrant spout
Technical field
The utility model relates to a kind of cutting tool of field of machining, is specifically related to a kind of outer dise knife of processing the fire hydrant spout.
Background technology
With cutter processing fire hydrant workpiece the time, in order to remove the burr at edge, also need to use the file filing, or carry out chamfering, when at present workpiece being carried out chamfering, the angle that needs tool changing or adjustment cutter, complex procedures is processed often, and the clamping cutter is cumbersome, both lost time like this, operating efficiency is low again.
The utility model content
At the problems referred to above, the purpose of the utility model pin provides a kind of i.e. outer dise knife of the convenient processing fire hydrant spout that uses, can increase work efficiency again.
The outer dise knife of processing fire hydrant spout, comprise handle of a knife and the cutterhead that is arranged on handle of a knife one end, the cutterhead lower surface is provided with first cutter hub, described first cutter hub is processed the periphery of fire hydrant spout, the lower surface of cutterhead also is provided with second cutter hub that is used for finished work is carried out chamfering, and described second cutter hub carries out chamfering to the workpiece that processes.
One end of described first cutter hub is provided with through hole, and the other end is provided with cutter head, and the relief angle of described first cutter hub is that 8 °, auxiliary angle are 30 °.
The blade of described second cutter hub comprises that one section inclination angle is 30 ° straight line sword and the circular arc sword that is arranged on straight line sword one end.
Described first cutter hub, second cutter hub are fixed on the cutterhead by screw.
Adopt such scheme, the outer dise knife of processing fire hydrant spout comprises handle of a knife and the cutterhead that is arranged on handle of a knife one end, and the cutterhead lower surface is provided with first cutter hub, and the lower surface of cutterhead also is provided with second cutter hub that is used for finished work is carried out chamfering.First cutter hub is processed the periphery of fire hydrant spout, second cutter hub carries out chamfering to the workpiece that processes, so only needs one procedure just can be finished the processing to the fire hydrant spout, the utility model is by being provided for second cutter hub of chamfering on cutterhead, like this workpiece one time forming cutting tool use very convenient, save the time of tool changing, improved operating efficiency.
