Abstract
The utility model discloses a taper rocker knife for manufacturing gas valves. The taper rocker knife for manufacturing the gas valves is provided with a cutter handle, a cutter body and a cutter head, wherein an end surface edge and a circular arc taper edge part are arranged on the cutter head, the circular arc taper edge part is composed of a circular arc concave edge and two taper edges, and an inner chamfering edge is arranged between the taper edges and the end surface edge. The taper rocker knife for manufacturing the gas valves has the beneficial effects that the production cost is saved, and the production efficiency is improved.
Description
Technical field
The utility model discloses a kind of cutter that is used for the processing gas valve.
Background technology
The gas valve outer wall adds man-hour, oxygen valve especially, and processing need be used severally cutter in the ordinary course of things, and the such words working (machining) efficiency is low, and production cost is than higher, and can not one-shot forming, and under the situation of several tool changing, machining accuracy also can't guarantee.
Summary of the invention
The utility model is many cutter at needing in the above-mentioned technology, and the machining accuracy shortcoming that can't guarantee, proposes a kind of cone circular arc cutter of integral type, and this cutter can once make oxygen valve machine-shaping.
The realization the technical solution of the utility model is as follows:
Processing gas valve cone circular arc cutter, it has handle of a knife, cutter hub and cutter head, and cutter head is provided with end face sword and circular arc awl blade, and circular arc awl blade is made up of the recessed sword of circular arc and two awl swords, is provided with interior chamfering blades between awl sword and the end face sword.
The radius of the recessed sword of described circular arc is 2.48mm-2.52mm.
The angle α of described two awl swords is 35 °.
Angle β in described between the chamfering blades is 120 °.
Adopted such scheme, the processing gas valve integrates the recessed sword of circular arc, awl sword, chamfering blades and end face sword with cone circular arc cutter, and to oxygen valve processing one-shot forming, useful benefit of the present utility model is to save production cost, enhances productivity.
