Abstract
The utility model relates to the field of manual cutting tools, in particular to a scraper for manually removing burrs. The scraper for removing the burrs comprises a scraper handle, a scraper rod and a scraper head. The scraper for removing the burrs is characterized in that the scraper head is arranged at the front end of the scraper rod, the scraper head and the scraper rod are in circular-arc transition connection, a cutting edge is arranged at the front end of the scraper head, and is a surface of intersection between an inner circular arc and an outer circular arc, and the ratio between the radius of the inner circular arc and the radius of the outer circular arc is 8:9. Compared with the prior art, the scraper for removing the burrs has the advantages that the structure is simple, exquisite and reasonable, the burrs on concealed flow passage holes such as decompression exhaust holes formed in a flow passage of a machine shell of a supercharger can be effectively removed, efficiency is high, the service life is long, and the risk is reduced.
Description
Technical field
The utility model relates to hand cutting tool field, is specially a kind of manual deburring scraper.
Background technology
In the booster casing processing of aluminium alloy, the runner concealed manhole places such as the pressure release steam vent in the runner of finished product are often jagged, these burrs are as removed not in time, can affect the product quality of booster casing, if fall into booster in product operation process, can directly affect the functional of booster, bring certain potential safety hazard, the method of deburring is at present to fall with file reconditioning, because pressure release steam vent is generally in the runner of finished product, shorter with the easy interference of common file and life-span, and removal effect is not good.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of deburring scraper simple in structure, ingenious, rational is provided, and this deburring scraper can be removed the burr at the runner concealed manhole places such as pressure release steam vent in booster runner fast and accurately.
The technical scheme providing according to the utility model: a kind of deburring scraper comprises handle of a knife, knife bar, cutter head, it is characterized in that described cutter head is arranged on the front end of knife bar, described cutter head is that arc transition is connected with knife bar junction, described cutter head front end is provided with cutting edge, described cutting edge is interior circular arc and external arc phase cross surface, and described interior circular arc and described outer arc radius ratio are 8: 9.
Described handle of a knife with knife bar for being fixedly connected with.
The thickness of described cutter head is less than the thickness of described knife bar.
Compared with prior art, advantage is the utility model: simple in structure, ingenious, reasonable, can effectively remove the burr at the runner concealed manhole places such as pressure release steam vent in booster casing runner, and efficiency is high, and the life-span is long, reduces risk.

The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, described a kind of deburring scraper, comprise handle of a knife 1, knife bar 2, cutter head 3, described handle of a knife 1 with described knife bar 2 for being fixedly connected with, described cutter head 3 is arranged on the front end of described knife bar 2, described cutter head 3 is that arc transition is connected with described knife bar 2 junctions, described cutter head 3 front ends are provided with described cutting edge 6, described cutting edge 6 is the phase cross surface of described interior circular arc 4 and described external arc 5, described interior circular arc 4 is 8: 9 with the radius ratio of described external arc 5, the material of described handle of a knife 1 is plastics, and the material of described knife bar 2 is high-speed steel.
In use, the right hand is held handle of a knife 1, and scraper is tilted, cutter head is put into runner, cutting edge 6 contacts with the burr at runner concealed manhole places such as pressure release steam vent in runner, and the right hand is held handle of a knife 1 and moved up and down, and burr can be removed, after cutting edge wearing and tearing, can carry out reconditioning with emery wheel and reuse.
This deburring scraper of the present utility model, simple in structure, good working effect, efficiency is high, and the life-span is long, reduces product risks.
