Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet metal working pad for a vehicle and a hammer for sheet metal working of a vehicle, and more particularly to a sheet metal working pad for a vehicle used for correcting a distortion or the like generated in a vehicle body or the like. The present invention relates to a metal and a hammer for sheet metal work of a vehicle.

[0002]

2. Description of the Related Art Generally, sheet metal work for a vehicle involves repairing a damaged portion with a hammer or the like. As this sheet metal work, apply a backing to the back side of the deformed curved surface,
It is repaired by hitting it from the front with a hammer. In general, metal is ductile and stretches when hit. Since such a small amount of deformation affects the surrounding curved surface, many years of experience and careful attention are required for sheet metal work.

[0003] In particular, it is said that a hammer having a flat hitting surface comes into point contact with a curved surface, and it is difficult to transmit uniform deformation stress to a repaired curved surface.

[0004] Since the object is a thin metal plate, if the object is hit as it is, a yield stress cannot be applied to the thin plate in the same manner as when a spring is hit, and the deformation cannot be corrected. Therefore, a metal plate is applied to the back side of the thin plate, and the object is placed on the metal plate. The object is momentarily hit with a hammer to correct the distortion. For this reason, the contact metal has a particularly strong force, does not need to be pressed, and is in a state of being in contact with the object without any gap.

[0005]

However, the hitherto used conventionally has been made of iron.
There is a considerable weight (for example, about 1.3 Kg to 1.4 Kg), and there is a problem that when holding it by hand and pressing it against the back side of the object, it is difficult to know how much force may be pressed. Therefore, there has been a problem that an unnecessary large force is applied or a pressing force is insufficient, so that a gap is formed between the pad and the hitting plate, thereby impairing the effect of hitting.

[0006] Also, if you press the backing strongly by hand,
There is a disadvantage that the impact of the hammer hits the hand strongly and the hand may become numb, and it is difficult to hold with one hand for a long time because the pad is heavy. In particular, there has been an inconvenience that a heat is applied to a hand holding the metal plate because the metal plate is heated by the sheet metal work.

[0007] In particular, the body panel of a vehicle has a different plate thickness between types of vehicles, for example, between a light car and a luxury car even if it is a passenger car. It is very difficult to learn the strength and the like, and it requires skill.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned inconvenience, and it is possible to perform a sheet metal work without requiring a skill to extend a thin plate, and to select an operator by appropriately selecting a weight. Can reduce the burden of
It is an object of the present invention to provide a sheet metal working pad having a high heat radiation effect. Another object of the present invention is to provide a sheet metal working pad and a vehicle sheet metal working hammer that can perform sheet metal work without skill.

[0009]

According to the present invention, the above object can be attained by forming a metal sheet working metal plate for a vehicle from an alloy of aluminum and zinc. At this time,
30% of zinc in the ratio of aluminum and zinc
As described above, or in the ratio of aluminum and zinc, aluminum is 70% or less. The specific gravity of zinc and iron does not change much. That is, the specific gravity of zinc is about 7.14.
Since the specific gravity of iron is about 7.86 and the specific gravity of aluminum is about 2.7, it is not only possible to reduce the weight by forming an alloy of aluminum and zinc, The alloy of aluminum and aluminum is easy to process, and can be easily processed into a substantially hexahedron as described later.

As described above, since the backing plate of the present invention is formed of an alloy of aluminum and zinc, the weight can be reduced. In particular, by appropriately adjusting the blending of aluminum and zinc, 400 g to 1000 g can be obtained. It is possible to adjust the weight to a degree. Therefore, when the thickness is small, a light metal can be used, and when the thickness is large, a heavy metal can be used. The adjustment of the striking force is not required by such different weights,
It is not necessary to perform the work of leveling from a thin plate to a thick plate with only a heavy iron ferrule as in the related art, and the leveling can be performed without skill. Further, since the metal plate made of an alloy of aluminum and zinc is easily processed, it can be easily processed so as to fit into the palm of an operator's hand.

[0011] Further, the object of the present invention is to provide a vehicle metal sheet work pad according to the present invention, which is a substantially hexahedral body, wherein a first width is a height, and a surface in a substantially horizontal direction with respect to the first width. The shorter one formed from the second width is the second width, the longer one is the third width, and the length ratio of the first, second, and third widths is 1: 2: 2.6.
The problem is solved by configuring to be in the range of １ ： 1: 2.4: 3.1.

Further, according to the present invention, there is provided a sheet metal working pad according to the present invention, which comprises a roughly hexahedron,
The three surfaces of the first side surface and the second side surface are flat, the upper surface is slightly curved, the side opposite to the first side is formed as a curved surface curved from the upper surface, and the opposite side of the second side is formed. Can be solved by forming the side surface as an inclined surface steeper than the curved surface.

As described above, by forming the area of the contact metal at a predetermined ratio, it becomes possible to use the metal object for the majority of the vehicle body when the vehicle is sheet-metaled. There is no need to use it, so
Since there is no need to select a large number of funds, skill for selecting the money is not required. As described above, it is possible to equalize the iron plate without extending it, or to equalize the inner surface of the groove and the reverse curved surface with one contact metal.

According to the above object of the present invention, in a hammer for sheet metal work of a vehicle according to the present invention, in a hammer in which a file is formed on a hitting surface, the file is defined by a horizontal reference line with respect to the horizontal with respect to a handle. Is formed by tilting from 10 degrees to 35 degrees.

As described above, since the file carved on the hitting surface is formed at a predetermined angle, the file can be accurately and evenly applied to the swinging of the arm when hitting. And it is possible to even out.

That is, a backing plate is applied to the back side of the corrected portion of the automobile body, the handle of the hammer is gripped, and the hammer is hit with the filed surface. Figure 8 shows the file and the thin plate.
Will be hit as shown by. When observing the surface of the file surface, a large number of minute projections are arranged with their tips sharpened, and these sharp minute projections engrave a large number of millimeter concave portions (milli scratches) on the metal curved surface. When a curved surface to be corrected is observed in millimeters, the portion is deformed only in the vertical direction by the scratches of the millimeter without extending in the surface direction.

By repeating this beating, the local correction is smoothly performed. In particular, when hitting with a hammer, that is, when hitting down the hammer, it hits the metal plate at a predetermined angle. Since it is formed at an angle of 35 degrees from the surface, the file can be hit directly on the surface of the metal plate in a horizontal state. For this reason, it is possible to accurately level at the impact location.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. The members, arrangements, and the like described below do not limit the present invention, and can be variously modified within the scope of the present invention.

FIG. 1 shows an embodiment of the present invention. FIG. 1 is a perspective view of a backing plate, FIG. 2 is a perspective view of a backing plate symmetrical with respect to the bottom surface of FIG. 3 is a bottom view of FIG. 1, FIG. 4 is a side view as viewed from the X side of FIG. 1, and FIG.
FIG. 5 is a side view as viewed from the Y side. 6 and 7 show an example of an embodiment of the hammer of the present invention. FIG. 6 is a perspective view of the hammer, FIG. 7 is an explanatory diagram of a file on a hitting surface, and FIG. 8 is a thin plate with a file. FIG.

The backing plate 10 in this embodiment is used for sheet metal work of a vehicle, and is made of an alloy of aluminum and zinc. At this time, in the ratio of aluminum and zinc, zinc is formed at 30% or more, or in the ratio of aluminum and zinc, aluminum is formed at 70% or less. The specific gravity of zinc is about 7.14, and the specific gravity of aluminum is about 2.7. Therefore, by appropriately adjusting the composition of aluminum and zinc, even if the shape is the same, 400 g to 1000 g of different weights can be obtained. Gold 10
Can be manufactured. The alloy of aluminum and zinc is cast using a sand mold under a predetermined composition.

The backing plate 10 manufactured as described above is processed by shaving the surface after casting. For processing, a desired shape that fits the operator's hand is obtained by shaving with a blade or using a file. Of course, if the shape of the metal plate 10 can be completely obtained as a desired shape depending on the mold, no processing is required.

The shape of the backing plate 10 is approximately 6 in this embodiment.
It is a planar body and has a symmetrical shape as shown in FIGS. This is because a vehicle usually has left and right bodies, and these are configured substantially symmetrically with respect to a center line in the vehicle traveling direction. It depends. As shown in FIGS. 1 to 5, the backing plate 10 has three surfaces, that is, a bottom surface 11, a first side surface 12, and a second side surface 13. First
The side surface 15 opposite to the side surface 12 is formed as a curved surface curved from the upper surface, and the side surface 16 opposite to the second side surface 13 is formed as an inclined surface steeper than the curved surface.

Since the outer shape of the backing metal 10 is made of an alloy of aluminum and zinc as described above, it can be easily processed, so that the cutting tool or the file is formed into a shape that fits the operator's hand. Formed.

The approximate size of the backing plate 10 is such that a first width A shown in FIGS. 3 to 5 is a height, and a shorter one formed from a surface in a substantially horizontal direction is the first width A. 2, the longer one is referred to as a third width C, and the length ratio of the first, second, and third widths A, B, and C is 1: 2: 2.6 to 1: 2.
The ratio is in the range of 4: 3.1.

Next, the hammer will be described. The backing plate 10 that is placed in contact with the back surface of the thin plate is hit with a hammer from the front surface side of the thin plate. A body panel that has been deformed due to an accident, etc. Leveled with a hammer.

The hammer 20 for sheet metal work of the vehicle of this embodiment is
A head 21 and a handle 22 are provided, and a file is formed on a hitting surface 23 of the head 21. The file eye is formed to be inclined from 10 degrees to 35 degrees with respect to the horizontal reference line with respect to the horizontal with respect to the handle 22.

Since the file formed on the hitting surface 23 is formed at a predetermined angle, when the user works with the elbow slightly apart from the side of the flank when hitting, the file becomes inconsistent with the swing of the arm. As shown in FIG. 7, it becomes a horizontal line, and it is possible to accurately and evenly contact the thin plate, and it is possible to evenly equalize.

That is, the backing 10 is applied to the back side of the corrected portion of the vehicle body, and the handle 22 of the hammer 20 is gripped.
It hits with the hitting surface 23 where the file was engraved. The file and the thin plate will hit as shown in FIG. When observing the surface of the file surface, a large number of minute projections are arranged with their tips sharpened, and these sharp minute projections engrave a large number of millimeter concave portions (milli scratches) on the metal curved surface. When a curved surface to be corrected is observed in millimeters, the portion is deformed only in the vertical direction by the scratches of the millimeter without extending in the surface direction. By repeating this beating, the local correction is performed smoothly.

In particular, when hitting with the hammer 20, that is, when hitting down the hammer 20, the elbow is slightly moved away from the side flanks, so that the metal plate is hit at a predetermined angle. Is from 10 degrees to 3 degrees with respect to this horizontal reference line, based on the horizontal
Since it is formed to be inclined at 5 degrees, the file eyes that have an angle to the handle 22 in advance can be thinned (metal plate) by swinging the arm.
On the surface of the file, the file can be hit as it is in a horizontal state. For this reason, it becomes possible to level evenly at the hitting point, and since the file becomes a nail and hits, it is deformed only in the vertical direction without extending in the surface direction. By repeating this beating, the local correction will be performed smoothly.

As described above, after the sheet metal work for correcting the deformed thin plate, the coating step is performed. Millimeter scratches are dispersed on the surface of the corrected curved surface, so paint adhesion is improved,
The paint finish is dramatically improved compared to the past. In addition,
In some cases, a putty material may be used, followed by a painting step.

As described above, according to the present invention, it is possible to carry out sheet metal work by preventing the thin plate from being extended without skill, and to reduce the burden on the operator by appropriately selecting the weight. In addition to this, it is possible to provide a metal sheet work pad for a vehicle having a high heat radiation effect. In addition, the present invention has been made to solve the above-described inconvenience, and it is possible to provide a sheet metal working pad and a sheet metal working hammer of a vehicle capable of performing sheet metal work without skill. According to the present invention,
It is possible to equalize the iron plate without extending it, or to equalize the inner surface of the groove and the reverse curved surface with one metal plate. That is,

According to the first to third aspects of the present invention,
Since it is formed of an alloy, the weight can be reduced. In particular, by appropriately adjusting the combination of aluminum and zinc, the weight can be adjusted to about 400 g to 1000 g. Therefore, when the plate thickness is small, a light metal plate can be used, and when the plate thickness is large, a heavy metal plate can be used. Since the adjustment of the striking force is not required by the metal plates having different weights as described above, there is no need to perform the work of leveling from a thin plate to a thick plate using only a conventional heavy metal plate. Leveling is possible without skill.

Further, since it is made of an alloy of aluminum and zinc, it is compared with a conventional metal plate made of iron,
Surface processing is extremely easy, and with a knife or file,
It is possible to obtain a desired shape, which makes it possible to easily form a shape that fits the hand of an operator, which was impossible with a conventional metal plate.

According to the fourth and fifth aspects of the present invention, by forming the area of the contact metal at a predetermined ratio, it is possible to use the metal contact for most of the vehicle body when the vehicle is sheet-metal. In addition, there is no need to use a large number of payouts. Therefore, there is no need to select a large number of payouts, so that skill for selecting a payout is not required.

According to the sixth aspect of the present invention, since the file carved on the hitting surface is formed at a predetermined angle, the file is accurately and evenly formed with respect to the swing of the arm when hitting. It becomes possible to hit, and it becomes possible to even out.
