Description
Technical field
It the utility model is related to cutting-tool engineering field, more particularly to a kind of instrument of simple and practical processing rubber washer.
Background technology
Rubber washer is the nozzle and spout position in sealed electronic pipe, prevents the foreign matters such as dust from entering in electron tube.Such as
Fig. 1, shown in 2, seal washer (sequence number 5) is circle, has certain thickness, thickness is generally 2mm.So material one of seal washer
As from thickness be 2mm silicon rubber, its diameter according to product difference and change.
The processing of existing rubber washer typically using injection moulding, punch process or draws knife processing.Wherein, injection moulding and punching press
Processing is required for special mould, and die cost is expensive, and cost is high, particularly with the less enterprise of electron tube annual production, every year
The demand of seal washer is little, buys special mould and just further increases cost；It is larger to draw knife processing dimension error, it is difficult to protect
The uniformity of seal washer outside dimension is demonstrate,proved, and workpiece is not fixed easily.
Utility model content
The utility model aims to provide the instrument of simple and practical processing rubber washer, can reduce production cost, while energy
Ensure the uniformity of seal washer outside dimension.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of instrument of simple and practical processing rubber washer, including the handle of a knife being coaxially disposed and annular cutter hub, the ring
There is circular blade shape cutter hub front end, and the inwall of the annular cutter hub is the face of cylinder, and the front end of the handle of a knife is connected with annular cutter hub,
There is axially arranged through hole in the handle of a knife, the through hole is connected inside annular cutter hub.
Wherein, the thickness of the circular blade is 0.2mm.
Further, the outer wall of the annular cutter hub is the conical surface.
Further, the taper of the conical surface is 4 ° to 6 °.
It is further preferred that the taper of the conical surface is 5 °.
Wherein, the through hole and handle of a knife are coaxial.
Further, the handle of a knife and annular cutter hub are integrally manufactured.
Wherein, the material of the handle of a knife and annular cutter hub is mould steel.
Compared with prior art, the utility model has the advantages that：
The utility model is simple in construction, and cost is cheap, and strong applicability is easy to process, and input cost is low, can ensure to process
The uniformity of efficiency and workpiece.
Brief description of the drawings
Fig. 1 is the top view of rubber washer；
Fig. 2 is the front view of rubber washer；
Fig. 3 is structural representation of the present utility model；
In figure：1- handle of a knifes, 2- annulars cutter hub, 3- circular blades, 4- through holes, 5- seal washers.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.
As shown in figure 3, the instrument of processing rubber washer simple and practical disclosed in the utility model, including be coaxially disposed
There is a circular blade 3 handle of a knife 1 and annular cutter hub 2, the annular front end of cutter hub 2, and the inwall of annular cutter hub 2 is the face of cylinder, the front end of handle of a knife 1
It is connected with annular cutter hub 2, there is axially arranged through hole 4 in handle of a knife 1, through hole 4 is connected inside annular cutter hub 2.Through hole 4 and handle of a knife 1
Coaxially.
The annular oral area internal diameter size of cutter hub 2 is consistent with the external diameter of seal washer, and the annular external diameter of cutter hub 2 is more bigger than its internal diameter
0.2mm or so, there is certain intensity to ensure that oral area cutting edge is sharp, i.e., the thickness of circular blade 3 is 0.2mm.
Cutting edge is sharpened for the ease of maintenance, to increase the service life, the outer wall of annular cutter hub 2 is the conical surface, the taper of the conical surface
Scope is 4 ° to 6 °, preferably, the taper of the conical surface is 5 °.Handle of a knife 1 and annular cutter hub 2 are integrally manufactured, handle of a knife 1 and annular cutter hub
2 material is mould steel, and grinding oral area forms after quenched, mill processing, easy to process, cost is low.
In use, clamping handle of a knife 1 with drilling machine, it will be positioned on the soft materials such as smooth plank, open for rapidoprint
Open drilling machine and push main shaft, so that it may easily process very much Work piece sealing packing ring.The utility model is removed from drilling machine,
Work piece sealing packing ring is disclosed from the annular front end of cutter hub 2 by through hole 4 with instrument, completes processing.
The utility model is simple in construction, and cost is cheap, and strong applicability is easy to process, and input cost is low, can ensure to process
The uniformity of efficiency and workpiece.
Certainly, the utility model can also have other numerous embodiments, without departing substantially from the utility model spirit and its essence
In the case of, those skilled in the art can make various corresponding changes and deformation, but these according to the utility model
Corresponding change and deformation should all belong to the scope of the claims appended by the utility model.
