Abstract

The utility model relates to a trimming knife and relates to a manual cutting tool. The trimming knife comprises a knife handle and a knife carrier fixedly mounted at one end of the knife handle; an L-shaped blade is arranged at the front end of the knife carrier, one end of the L-shaped blade is connected with the knife carrier, and a cutting edge is formed at the other end of the L-shaped blade, the plane of the cutting edge is basically perpendicular to the knife carrier, and therefore, the trimming knife is better in deburring capacity and capable of realizing treatment in deep gaps without fixed shape. The knife carrier of the existing trimming knife is of simple linear structure, and as a result, some irregular corner dead angles in gaps cannot be treated completely, the burrs cannot be removed thoroughly, and furthermore, the quality of the workpieces can be affected. The trimming knife is capable of clearing the irregular corner dead angles in the gaps and the deep gaps without fixed shape, and the trimming working efficiency can be improved.

Description

Edge iron

Technical field

The utility model relates to a kind of hand cutting tool, is specifically related to the hand knife of fixed blade.

Background technology

Past, there are burr between gap in machine in the production line of factory, and traditional burr removing mode is to adopt file, sand paper, bistrique to remove the object of polishing, but exist many weak points:

1, adopt file efficiency low and relevant with workman's qualification, easily affect the surface smoothness of product;

2, sand paper cleaning burr, efficiency is too low, uses for a long time workman's fatiguability, and is not durable;

3, bistrique noise is high, and dust is many, and danger coefficient is large;

, in the production line of factory, conventionally adopt burr removing machine to clear up in large quantity the burr between machine gap, but some tiny local burr removing machine but cannot complete now, so just must adopt manual edge iron to go processing.Manually edge iron uses safe, quick and easy, noiseless dust pollution, and by smear metal burr removing, use is extremely simple and less demanding to workman's qualification, and the fineness of removing behind burr edge is that traditional approach institute is unmatchable.

Its knife bar of existing edge iron is easy linear structure, when cleaning burr, always have random tortuous dead angle under some gaps, the blade of linear structure edge iron can not bend, thereby cannot stretch in these random tortuous dead angles and clear up burr, cause thoroughly removing burr, affect the quality of workpiece.

Utility model content

The purpose of this utility model is to provide a kind of edge iron, and this edge iron, by its improved " L " shape blade energy handled easily, is thoroughly removed burr, and improves deburring operating efficiency.

The utility model is a kind of edge iron, comprise handle of a knife and the knife bar that is fixedly mounted on handle of a knife one end, the front end of described knife bar is provided with " L " shape blade, its " L " shape blade one end is connected with knife bar, and the other end is provided with blade, the curved setting-out in longitudinal section of " L " shape blade, " L " shape blade is connected one end width with knife bar is greater than the width of blade one end.

The feature of technique scheme is, improved " L " shape blade energy handled easily, and its blade place plane is substantially vertical with knife bar, can clear up random tortuous dead angle under those gaps and there is no the zanjon gap of relative solid shape, improve deburring operating efficiency.

Further, described blade place plane is substantially vertical with knife bar; Remove burr ability stronger, can clear up those and not have figurate zanjon gap.

Further, the handle of a knife of described fixed installation knife bar is coated with rubber layer; To guarantee wearability and the non-skid property of handle of a knife.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

A kind of edge iron, structure as shown in Figure 1, comprise handle of a knife 1 and the knife bar 2 that is fixedly mounted on handle of a knife one end, the front end of knife bar 2 is provided with " L " shape blade, its " L " shape blade 3 one end are connected with knife bar 2, and the other end is provided with blade 31, and its blade 31 place planes are substantially vertical with knife bar, remove burr ability stronger, can clear up under those gaps random tortuous dead angle and not have figurate zanjon gap.Described knife bar 2 is provided with LED lamp, and the one side towards knife bar on blade is reflective surface, and LED lamp is aimed at the reflective surface of blade, can reflect LED light source by reflective surface narrow positions is irradiated.

Handle of a knife 1 in the utility model adopts rubber layer, is in order to guarantee wearability and the non-skid property of handle of a knife 1.

The utility model is when work, the handle of a knife 1 of holding with a firm grip, " L " shape blade 3 is placed in and needs the groove of deburring to remove its burr, for that, relatively do not have a figurate zanjon gap, utilize the characteristic that its blade 31 is sharp, adopt back and forth manner of cleaning up round to reach the object of deburring, to increase its edge-light cleanliness.

Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.

Claims

1. an edge iron, comprise handle of a knife and the knife bar that is fixedly mounted on handle of a knife one end, it is characterized in that: the front end of described knife bar is provided with " L " shape blade, its " L " shape blade one end is connected with knife bar, the other end is provided with blade, the curved setting-out in longitudinal section of " L " shape blade, " L " shape blade is connected one end width with knife bar is greater than the width of blade one end.

2. edge iron as claimed in claim 1, is characterized in that: described blade place plane is substantially vertical with knife bar.

3. edge iron as claimed in claim 1, is characterized in that: the handle of a knife of described fixed installation knife bar is coated with rubber layer.
