[0001]
[Technical field to which the invention belongs]
The present invention relates to a sheet metal working straps of the vehicle, in particular it relates to a sheet metal working straps of the vehicle to be used for correcting the distortion and the like generated in the vehicle body of the vehicle.
[0002]
[Prior art]
In general, as a sheet metal work of a vehicle, a damaged part is repaired with a hammer or the like. In this sheet metal work, a metal plate is applied to the back side of the deformed curved surface and repaired by hitting it from the front side with a hammer. Generally, since metal is ductile, it extends when struck. Since this small amount of deformation affects the surrounding curved surface, sheet metal work requires years of experience and careful attention.
[0003]
In particular, a hammer having a flat strike surface is in point contact with a curved surface, and it is said that it is difficult to transmit uniform deformation stress to a repaired curved surface.
[0004]
And since a target object is a metal thin plate, if it hits as it is, yield stress cannot be given to a thin plate similarly to hitting a spring, and 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. For this reason, it is set as the state which is in contact with the target object in the state which does not need to press with a particularly strong force and does not need to press a gap, and there is no clearance gap.
[0005]
[Problems to be solved by the invention]
However, the conventionally used stopper is made of iron and has a considerable weight (for example, about 1.3 kg to 1.4 kg), which is held by hand on the back side of the object. In the case of pressing, there is a problem that it is difficult to know how much force to press. Therefore, there is a disadvantage that an unnecessary large force is applied or a pressing force is insufficient and a gap is formed between the pad and the impact effect.
[0006]
In addition, if the metal pad is pressed firmly with your hand, the impact of the hammer hits your hand strongly, and your hand may become numb, and the metal pad is heavy, so it is difficult to hold it with one hand for a long time. is there. In particular, since the metal plate is heated by the sheet metal work, there is an inconvenience that heat is applied to the hand holding the metal plate.
[0007]
In particular, the body panel of a vehicle has a different thickness between the type of vehicle, for example, a passenger car or a light car and a luxury car. It was very difficult to master these, and skill was required.
[0008]
The object of the present invention is to solve the above inconvenience, and it is possible to perform sheet metal work by preventing the extension of a thin plate without requiring skill, and to reduce the burden on the operator by appropriately selecting the weight. it is possible to lightly Ru near to provide a sheet metal working straps of radiating effect high vehicle.
[0009]
[Means for Solving the Problems]
The above object is achieved according to the sheet metal working straps of the vehicle of the present invention, the ratio of A aluminum and zinc, of zinc of 30% or more, or aluminum of the aluminum and the zinc is less than 70% alloy vehicle The sheet metal working metallurgy of the vehicle is formed in a substantially hexahedron shape that can be held with one hand, and has a first width as a height, with respect to the first width. The shorter one formed from the substantially horizontal surface is the second width, the longer one is the third width, and the length ratio of each of the first, second, and third widths is 1: 2: 2. 6 to 1: 2.4: by the range near Rukoto of 3.1, is resolved. The specific gravity of zinc and iron is not much different. That is, the specific gravity of zinc is about 7.14, the specific gravity of iron is about 7.86, and the specific gravity of aluminum is about 2.7. Therefore, by making an alloy of aluminum and zinc, In addition, the alloy of zinc and aluminum is easy to process, and can be easily processed into a roughly hexahedron as described later.
[0010]
Thus, since the metal base 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, the weight of about 400 g to 1000 g. Adjustment is possible. Therefore, when the plate thickness is thin, a light pad can be used, and when the plate is thick, a heavy pad can be used. Since the adjustment of the striking force is not necessary due to the 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 plate as in the past. Leveling is possible without requiring skill. Further, since the metal base made of an alloy of aluminum and zinc is easy to process, it can be easily processed to fit the palm of the operator.
[0012]
Further, according to the sheet metal working metallurgy of the vehicle of the present invention, the above-described problem is made of the alloy of aluminum and zinc in which the ratio of aluminum to zinc is 30% or more, or aluminum is 70% or less. A sheet metal working pad for a vehicle, wherein the sheet metal working pad for the vehicle is formed in a substantially hexahedron shape that can be held with one hand, and the hexahedron includes a bottom surface, a first side surface, and a second side surface. The side surface of the first side surface is a slightly curved surface, the side surface opposite to the first side surface is formed as a curved surface curved from the top surface, and the side surface opposite to the second side surface is the curved surface. It is solved by forming it as a steep inclined surface.
[0013]
In this way, by forming the area of the metallization at a predetermined ratio, it becomes possible to use the metallurgy of most body parts when sheeting a vehicle, and it is necessary to use a large number of conventional metallurgy. This eliminates the need to select a large number of deposits, thus eliminating the need for skill to select the deposits.
As described above, it is possible to level the steel plate without extending it, or level the inner surface of the groove and the reverse curved surface with a single pad.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The members, arrangements, and the like described below are not intended to limit the present invention and can be variously modified within the scope of the gist of the present invention.
[0019]
FIG. 1 shows an example of an embodiment of the present invention, FIG. 1 is a perspective view of a stopper, FIG. 2 is a perspective view of a stopper that is symmetrical with respect to the stopper and the bottom of FIG. 1, and FIG. 1 is a bottom view, FIG. 4 is a side view seen from the X side of FIG. 1, and FIG. 5 is a side view seen from the Y side of FIG. 6 and 7 show an example of the embodiment of the hammer according to the present invention. FIG. 6 is a perspective view of the hammer, FIG. 7 is an explanatory view of a file of a hitting surface, and FIG. 8 is a thin plate by the file. It is explanatory drawing when leveling.
[0020]
The pad 10 in this example is used for vehicle sheet metal work, and is formed of an alloy of aluminum and zinc. At this time, the ratio of aluminum to zinc is 30% or more, or the ratio of aluminum to zinc is 70% or less of aluminum. Since the specific gravity of zinc is about 7.14 and the specific gravity of aluminum is about 2.7, by adjusting the blending of aluminum and zinc as appropriate, different weights ranging from 400 g to 1000 g can be obtained even for the same shape. Gold 10 can be manufactured. This aluminum and zinc alloy is cast using a sand mold under a predetermined composition.
[0021]
The metal base 10 manufactured in this way is processed by shaving the surface after casting. For the processing, a desired shape that fits the operator's hand is obtained by cutting with a blade or using a file. Of course, if the shape of the pad 10 can be obtained as a completely required shape by using a mold, no processing is required.
[0022]
In addition, the shape of the stopper 10 is approximately a hexahedron in this example, and is a symmetrical shape as shown in FIGS. 1 and 2. This is because a vehicle usually has left and right bodies, and these are configured substantially symmetrically with respect to the center line in the vehicle traveling direction. Depending on what is preferred.
As shown in FIGS. 1 to 5, the pad 10 has a bottom surface 11, a first side surface 12, and a second side surface 13, each having a substantially flat surface, and an upper surface 14 having a slightly curved surface, A side surface 15 opposite to the first side surface 12 is formed as a curved surface curved from the upper surface, and a side surface 16 opposite to the second side surface 13 is formed as an inclined surface steeper than the curved surface.
[0023]
Since the processing of the outer shape of the pad 10 is made of an alloy of aluminum and zinc as described above, it can be easily processed, so that it is formed in a shape that fits the hand of the operator with a knife or a file. .
[0024]
The rough dimension of the stopper 10 is such that the first width A shown in FIGS. 3 to 5 is the height, and the shorter one formed from the substantially horizontal surface is the second width with respect to the first width A. B, the longer one is the 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: 2.4: 3. .1 in the range.
[0025]
Next, the hammer will be described. The metal plate 10 that is placed in contact with the back of the thin plate is hit with a hammer from the front side of the thin plate, and the body panel that has been deformed due to an accident or the like is engraved on the striking surface so that the iron plate does not extend. Leveling with a hammer.
[0026]
The sheet metal working hammer 20 of the vehicle of this example is composed of a head 21 and a handle 22, and a file is formed on the hitting surface 23 of the head 21. Then, the file eyes are formed so as to be inclined by 10 to 35 degrees with respect to the horizontal reference line when the horizontal with respect to the handle 22 is used as a reference.
[0027]
Since the file engraved on the striking surface 23 is formed at a predetermined angle, when striking, when the elbow is moved a little away from the flank, the file is shown in FIG. As shown, it becomes a horizontal line, and can be applied accurately and evenly to the thin plate, and can be evened evenly.
[0028]
That is, the metal pad 10 is applied to the back side of the corrected part of the vehicle body of the vehicle, the handle 22 of the hammer 20 is gripped, and the hitting surface 23 in which a file is engraved is struck. The file and the thin plate will hit as shown in FIG. When the surface of the file surface is observed, a large number of microprotrusions are arranged with sharp tips, and the sharp microprotrusions engrave a large number of millimeter recesses (millimeter scratches) on the metal curved surface. When the curved surface to be corrected is observed in millimeters, the part does not extend in the surface direction due to scratches on the millimeters, but is deformed only in the vertical direction. By repeating this strike, the local correction is performed smoothly.
[0029]
In particular, when the hammer 20 is hit, that is, when the hammer 20 is dropped, the elbow is moved slightly away from the flank, so that the metal plate is hit at a predetermined angle. Since it is formed with an inclination of 10 to 35 degrees with respect to the horizontal reference line, the file with an angle with respect to the handle 22 in advance is a thin plate ( On the surface of the (metal plate), the file can be hit as it is in a horizontal state. For this reason, it becomes possible to level the ball accurately at the striking location, and the filed eye hits as a claw, so that it does not extend in the surface direction but deforms only in the vertical direction. By repeating this strike, the local correction is smoothly performed.
[0030]
As described above, the coating process is executed after the sheet metal work for repairing the deformed thin sheet. Since the surface of the modified curved surface has millimeter scratches dispersed, the adhesion of the paint is improved and the finish of the coating is dramatically improved compared to the conventional one. In some cases, a putty material is used, and then the painting process is performed.
[0031]
【The invention's effect】
As described above, according to the present invention, it is possible to perform sheet metal work by preventing the extension of a thin plate without requiring skill, and to reduce the burden on the operator by appropriately selecting the weight, and to dissipate heat. It is possible to provide a sheet metal working pad for a vehicle that is highly effective. Further, the present invention has been made to solve the above inconveniences, and it is possible to provide a sheet metal working pad and a vehicle sheet metal working hammer that can perform sheet metal work without requiring skill. In addition, according to the present invention, it is possible to level the iron plate without extending it, and level the inner surface of the groove and the reverse curved surface with a single pad. That means
[0032]
According to the first and second aspects of the present invention, since the backing metal is made of an alloy, it is possible to reduce the weight, and in particular, by appropriately adjusting the blending of aluminum and zinc, a weight of about 400 g to 1000 g. Adjustment is possible. Therefore, when the plate thickness is thin, a light pad can be used, and when the plate is thick, a heavy pad can be used. Since the impact force does not need to be adjusted due to the different weights in this way, it is not necessary to perform the work of leveling from a thin plate thickness to a thick one using only a heavy iron strike plate as in the past. Leveling is possible without requiring skill.
[0033]
In addition, since it is made of an alloy of aluminum and zinc, it is extremely easy to surface-treat as compared to a conventional metal plate made of iron, and it can be made into a desired shape with a blade or a file. As a result, it was possible to easily form a shape that fits the hand of the operator, which was impossible with a conventional pad.
[0034]
According to the first and second aspects of the present invention, by forming the area of the metal plate at a predetermined ratio, it is possible to use the metal plate of the vehicle body as a metal plate when the vehicle is sheet metal. There is no need to use a deposit . For this reason, it is not necessary to select a large number of deposits, so that skill for selecting a deposit is not required.
