Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protective surface for welding which is excellent in usability because a welded object and an object to be welded can be easily recognized in a preparatory stage in a welding operation and the process can be immediately and safely transferred to the welding process.

[0002]

[Prior art]

 Generally, a protective surface for welding is used to protect the eyes and face from harmful rays and spatters generated during welding. The protective surface for welding is a light-shielding see-through plate in the part corresponding to the eyes. A window is formed by attaching a (shading plate) or filter glass to block harmful rays during welding so that the welded area will be at an appropriate brightness so that work can be performed. It is roughly divided into a helmet type that is attached to the front of the face and a hand type that attaches a handle and positions the face body on the front of the face by hand.

[0003]

[Problems to be solved by the device]

 For the conventional welding protection surface described above, in order to move to the welding work after confirming the welding location and setting the welding tool in the preparation stage, if it is a helmet type, open the light shield plate of the window part or the surface main body. It is necessary to remove the shading plate from the eye position by raising or lowering it, and then return the shading plate or the surface main body of the window to the original position again. It is necessary, and there is a problem that one hand is blocked, and it is not possible to perform fine welding work.Therefore, there are few points in terms of accuracy, finish, speed, etc. on the welding work due to the configuration that can not be seen through in the normal state. It has a negative impact. In addition, there are those where the window of the welding protection surface is made of liquid crystal material and changes color in response to light rays during welding, and there are those where the window can be opened and closed automatically by a sensor. Welding points can be confirmed and harmful light rays are automatically blocked at the beginning of the welding process, but all of them are very expensive and easily damaged due to rough use. It is hard to say that it is a tool suitable for contact work sites.

The present invention has been made in view of the above points, and visually recognizes a welded portion by the naked eye due to a slight change in the angle of the head and shields harmful rays during welding (eye protection by a light shielding plate). It is possible to easily perform the setting operation and welding operation switching operation at the preparatory stage, and reduce the labor required for the operation.The movement of the welding surface body and the opening / closing operation of the window are unnecessary, and the hands are free. The purpose is to provide a protective surface for welding that has improved workability such as being usable.

[0005]

[Means for Solving the Problems]

 The gist of the present invention for achieving the above-mentioned object is that a window portion of a protective surface main body having a light-shielding plate for shielding harmful rays is provided with a visual recognition portion that can be visually observed obliquely forward with the naked eye. It is a characteristic welding protection surface.

[0006]

[Action]

 As described above, with the welding protection surface of the present invention, it is sufficient to move the head so that the welded part can be seen through the visible part during setting in the preparation stage. If it is a visible part, the face should be adjusted so that the welding point is on the extension line of the eye and the visible part when using the upper eye, and if the visible part can be seen diagonally forward and downward, face up. Adjust it and use the lower eye so that the welding point comes on the extension line of the eye and the visible part.Next, when entering the welding work, face the front of the welding point or set it. The harmful light rays generated during welding may be turned in a direction slightly opposite to the time and used in a state of being shielded by the light shielding plate of the window. As described above, it is possible to switch between the window with a light shield and the visual part where the front can be visually recognized with the naked eye only by the angle of the face (head), which is extremely effective for welding work. Since it does not use a sensor or a special light-shielding plate, it is not easily damaged even with rough handling, and it has sufficient durability.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention.

In the drawings, reference numeral 1 denotes a protective surface main body, which has an area capable of covering the entire face, forms a window portion 2 at a position corresponding to the eyes, and allows a diagonally forward view to be visible to the window portion 2 with the naked eye. The protective surface main body 1 covers the face at the time of mounting by providing a recognition part 3 and further attaching an annular frame 4 for mounting on the upper part of the surface main body. The window portion 2 of the protective surface body 1 is formed of a light-shielding see-through plate (light-shielding plate) that blocks harmful rays during welding, and the light-shielding plate is a plate member such as a dark acrylic resin plate or a dark light-shielding glass plate. The visual recognition portion 3 provided at the upper end position of the window portion 2 is made of a material such as a colored glass plate or a colored resin plate that allows the front to be seen through in a normal state.

FIG. 3 is a perspective view showing another embodiment of the present invention, in which the main welding protection surface is formed so that the window portion 2 is projected and the visual recognition portion 3 is inclined. If it is a protective surface, it is very easy to see the front situation and the position of each member when the face is lowered before welding. It has excellent usability.

The protective surface shown in FIG. 4 is formed by arranging a plurality of light-shielding plates in the shape of an armor plate to form the window portion 2 of the protective surface main body 1. The visible portion 3 is provided so that only the light shielding plate can be seen in the open state, and the front state can be seen from between the respective light shielding plates when the face is slightly on the back. The visible portion 3 may be left as it is, but as shown in FIG. 6, a colored glass plate 5 or a colored resin plate, a transparent plate, or the like, which can see through the front in a normal state in the front part (or the rear part), is used. You may attach it. Further, it is also effective that the light shielding plates forming the window portion 2 are matted or the like so as to be made of a non-reflective material so as to prevent harmful rays from entering from the visual recognition portion 3 during the welding operation.

Further, it is conceivable to form the visible portion 3 of the window portion 2 so as to be openable and closable in the window portion 2 in which a plurality of light shielding plates are arranged in an armor shape. It is formed so that it can be moved, and in the preparatory stage before welding, the shading plate is positioned in a state close to horizontal, and during the work, the shading plate moves to a state parallel to the protective surface body 1 as shown in FIG. The visible portion 3 may be closed, or a plurality of light shield plates may be fixed and a slide light shield plate that closes the visible portion 3 may be provided at an appropriate position of the window portion 2, and a slide light shield plate may be slid as necessary. Then, the slide light-shielding plate is located at the position of the visual recognition part 3. By forming the visual recognition part 3 of the window part 2 in such a manner that it can be opened and closed, the utility value of the welding protection surface can be improved. It can be further increased.

FIG. 8 shows a protective surface in which a plurality of light-shielding plates are not arranged in a parallel state in an armored shape, but the light-shielding plates are arranged upside down and the window portion 2 is provided with a visual recognition portion 3. This protective surface can prevent harmful rays during welding work from being reflected on the shading plate and entering the eyes.

In addition, when the welding protection surface of the present invention is attached, there are individual differences such as eye positions depending on the user, so that the most suitable window position and viewing portion position and angle can be obtained. If a member such as the light-shielding plate 2 and the colored glass plate of the visual recognition portion 3 is formed so as to be capable of rotational movement and slide movement, the window portion 2 and the window portion 2 that are suitable for the position of the user's eyes during use can be obtained. It is enough to position the visual recognition part 3 so that the welded part can be easily seen from the visual recognition part 3 without tilting the head at an unreasonable angle, and a state where harmful rays do not enter the eyes during welding work is ensured. It is possible to provide a more effective welding protection surface by making it extremely easy to use. Further, it may be formed by replacing the conventional window portion of the protection surface with the window portion and the visual recognition portion shown in the present invention so as to be used in the existing protection surface.

FIG. 9 is a perspective view showing a welding work instrument A with a light shield plate attached to a welding holder or the like, and this light shield plate is also provided with a window portion 2 similar to the window portion 2 of the protection surface. In consideration of the above, by providing the visual recognition part 3 composed of a colored glass plate or a colored resin plate, etc., which can see through the front in a normal state, in the entire area (or part) of the window portion 2, it is possible to reduce the labor required for the work. That is, it is possible to significantly reduce the time and effort required to move the head from the welding work confirmation work to the welding work in the preparation stage.

[0016]

[Effect of device]

 As described above, according to the present invention, it is possible to visually confirm the welded portion by moving the head by a slight angle, and the head is again positioned directly in front of the welded portion. By directing it, it is possible to immediately enter the state of welding work, so the switching operation between the preparation stage and the welding stage is extremely easy, the labor related to the entire welding work can be reduced, and it is in the setting state. Since there is no need to move both hands, if the welding work is directly entered, the welding location can be accurately grasped, so that a beautiful finish can be obtained without the displacement of the welding location.
