DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a method of repairing an automobile body or the like having a dent, a linear groove or the like by sheet metal work by pulling a welded body welded to the dent or the linear groove. The present invention relates to a sheet metal repair pull plate hanger used to make a surface.

[0002]

2. Description of the Related Art Conventionally, a hammer is movably supported by a shaft having a hook at a front end and a stopper at a rear end, which is used for repairing a damaged portion of a concave shape of an automobile body or the like. A hammer-type puller device for sheet metal (hereinafter, referred to as a "hammer-type puller device") is well-known, and a hook of the hammer-type puller device is attached to a welding body such as a hole opening pin or a drawer washer spot-welded to a dent portion or the like. After being hooked directly, the hammers are moved manually to collide with the stopper, and the dents and other parts are individually pulled out one by one (hereinafter simply referred to as “individual drawer”) and smoothed. I have.

According to the above-mentioned hammer-type puller device, since the device itself is small and can be finely worked, it is convenient when individual small local dents or the like are individually repaired one by one. However, there is a limit to the pulling force of the hammer by manual operation, and it is difficult to pull out evenly when the range of the drawer is wide, and it is not suitable for use when the concave shape is streaked. .

In order to solve the problem of the limit of the pulling force of the above-mentioned hammer-type puller device, Japanese Utility Model Application Laid-Open No. 59-19 / 1984.
No. 6909 (Japanese Utility Model Application Laid-Open No. 61-117322), a pair of legs that can be brought into contact with the sheet metal surface is penetrated at a central position in a direction orthogonal to the longitudinal direction to guide a movable rod. A support rod having a hole is slidably supported, the ends of a pair of operation arms are pivotally supported on the left and right sides of the through hole, and an intermediate position of the operation arm and the connection piece are connected by a connection rod. 2. Description of the Related Art A booster-type sheet metal puller device (hereinafter, referred to as a "power-boosting puller device") having a configuration in which a movable bar is moved and moved in a vertical direction by a booster has been developed.

[0005] Further, when the concave shape of the body of an automobile or the like is streak-like, an attachment for pulling out and repairing the streak-like concave portion at once is provided with a hanging main ring along the upper edge of the hanger main body. Side suspension rings are provided at the left and right target positions, and a large number of comb-shaped support plates are arranged and formed on the lower edge side of the hanger main body, and a hanger hole penetrating each support plate in the horizontal direction is formed, and a rear end is formed. 10-20 free hangers, each of which is formed with a shaft hole at its end and whose tip is formed on a hook for hooking, are arranged between the support plates with the tip opening side of the hook for hooking facing the same side perpendicular to the axis. A pull plate hanger has also been developed which is provided so as to be supported by a hanger shaft.Along the streak-shaped recessed portion, a number of washers for pull-out are lined up by welding means so that the center holes of the washers coincide with each other, or Is After welding the peaks (valleys) of the corrugated metal wire in a form meandering at a predetermined pitch while keeping the height constant, the hook for hooking is hooked on the washer for drawing or the corrugated metal wire. Then, a hook main body attached to the movable shaft of the above-mentioned booster type puller is hung on the main pulling ring for pulling and pulled, and the streak-shaped dent portion is simultaneously pulled out (hereinafter simply referred to as "simultaneously pulling out") and repaired. ing.

[0006] When the concave shape of the body of an automobile or the like is streak-like, the streak-like concave portion is not always constant in depth but may be partially deep.
In such a case, if the simultaneous pull-out operation is directly performed using the above-described pull plate hanger, the pull-out force acting on each portion of the streak-shaped dent portion is poor, so that even pull-out cannot be performed, and the smooth recovery is performed. Can not do it. For this reason, as a pre-process for performing a pull-out operation using the pull plate hanger, it is necessary to draw out deep dents individually using a hammer-type puller device to make the depths of the streak-shaped dents uniform.

[0007]

However, irregularities in the depths of the streak-shaped dents are difficult to see from the outside, and even if the depths of the streak-shaped dents seem to be equal at first glance, the pull plate hanger cannot be used. If it is attached and pulled out all at once, it may not be possible to pull it out evenly.In such a case, remove the hooks of the pull plate hanger from all the washer for pulling out, and separate the deep parts individually with a hammer type puller device. Post-processing must be performed.

Further, when it becomes necessary to repeat this work, the hook for hooking must be re-engaged with the washer for drawer again to perform the simultaneous drawer, which requires patience and skill in the operator. There is a drawback that the work efficiency is extremely low because a large amount of work time and labor are required.

[0009] Further, in the case of pulling out the streak-shaped dent portion having a non-constant depth, it is necessary to perform an individual pull-out operation for partially adjusting the depth of the streak-like dent portion as described above.
A welded body that can be individually pulled out must be used, and it is not appropriate to use a corrugated metal wire consisting of a single metal wire. In addition, it is necessary to arrange them at equal intervals, and in addition, there are many operations for hooking and removing the hooks of the pull plate hangers on these washers, so that a lot of trouble is required, and these operations also take a lot of time. It was inefficient and time-consuming.

The present invention makes it possible to simultaneously carry out individual drawers and simultaneous drawers even when the concave shape of an automobile body or the like is a streak and is partially deep. The welding work can be efficiently welded to the repaired surface, and the connection work between the welding body and the pull plate hanger for sheet metal repair is not required, requiring no skill and greatly reducing the work time and labor. An object of the present invention is to provide a sheet metal repair pull plate hanger capable of improving efficiency.

[0011]

The welded body (3) will be described in detail. As shown in FIG. 3, the welded body (3) comprises a welding base (31), a bit (40) and an insulator (38). Welding base
Both the bit (31) and the bit (40) are made of steel, and the insulator (38) is made of Duracon (registered trademark) having high insulation and impact resistance.

A top portion is formed in a concave pressing portion (32) for pressing an electrode rod of a spot welding machine used at the time of welding described later on the upper portion of the welding base (31), and a hexagonal nut is formed on a side portion. A head terminal (33) formed with the head terminal (33)
A hook (34) for hooking the tip of the shaft of the hammer-type puller device at the time of individual pull-out is provided immediately below, and the hanger plate (2) is pierced below the hook (34). Diameter 11.9 mm, length 5 supported by sliding through hole 21
0 mm shaft portion (36), upper flange (35) for restricting the sliding of the welding base (31) down the shaft, and a lower portion of the shaft portion (36) for mounting the bit (40). The female screw portions (37) are formed integrally by cutting means.

When the insulator (38) is inserted into the through hole (21) of the hanger plate (2), the insulator (38) is interposed between the weld substrate (31) and the through hole (21). For electrically insulating the welding base (31) and the hanger plate (2), and has a length of 50 mm, an outer diameter of 14.2 mm, and an inner diameter of 12.1 m.
The lower flange (39) for restricting the sliding of the welded body (3) above the shaft is formed at the lower part in a cylindrical shape of m. Although the flange of the insulator (38) is formed only between the lower surface of the hanger plate (2) and the welded body (3), the bit (40) of the welded body (3) is repaired during the welding work described below. At the same time, the hanger plate (2) itself is also moved toward the restoration surface, so that the insulation state is secured. However, the upper flange (3
If an insulator such as a washer made of DURACON (registered trademark) is interposed also between the upper surface of the hanger plate 2 and the hanger plate 2, the insulation state can be ensured more reliably.

The bit (40) is directly welded to a repaired surface of an automobile body or the like by a later-described welding means. The bit tip (41) has a length of 15 mm. A hexagonal shaft portion (42) used at the time of screwing into the shaft portion (36) of the base (31) is provided at the center portion, and a male screw screwed into the female screw (37) of the shaft portion (36) at the upper portion. Forming a screw portion (43);
(31) The hanger plate (2) together with the insulator (38)
Then, it is screwed into the male screw part (43) via a washer (45) and a lock nut (44), and is fixed in a conductive state with the welding base (31). In this state, the welded body (3) is hanger plate
(2) It can slide about 7 mm in the vertical axis direction with respect to (2). When the bit (40) is welded, the bit tip (41)
Is consumed, so it is necessary to replace it appropriately according to the degree of wear.

Next, a description will be given of a case in which a streak-shaped concave portion of an automobile body, which is partially deepened, is repaired by using the above-mentioned pull-plate hanger for sheet metal repair according to the present invention. First, to fix the pull-plate hanger for sheet metal repair to the repair surface, connect one electrode rod of the spot welder to the ground adjacent to the streak-shaped recess on the car body, and then weld each The tip (41) of the bit of the body (3) abuts on the repair surface.
If the protrusion amount of the bit (40) is not constant between the welded bodies (3), the pulling force cannot be balanced at the time of subsequent simultaneous pulling, so that a flat plate such as a plate is previously attached to the bit tip (41). Check the length of the bit (40) of each welded body (3) by contact, and if they are not aligned, adjust the protrusion of the bit (40) by screwing the bit (40) into and out of the welding base (31). It is necessary to carry out bit length adjustment work to make the entire length of each welded body (3) uniform.

With the bit tip (41) of each welded body (3) in contact with the repair surface, the other electrode rod of the spot welding machine is applied to the pressing part (32) of the welded body (3) by about 2 kgf. Press with force,
When the bit tip (41) is pressed against the repaired surface, current flows only to the welded body (3), and the bit tip (41) and the repaired surface are spot-welded quickly, and the other welded body (3) is sequentially welded. In the same way, if welding is performed on the repaired surface, the pull plate hanger (1) for sheet metal repair is supported by the welded body (3) and quickly fixed on the car body without using a washer for pulling out. The Rukoto. At this time, if the electrode rod is pressed so as to be aligned with the center axis of the welded body (3), it can be pressed with relatively light force.
The gripping part (52) is mounted so as not to cover the central axis of the welded body (3) so as not to hinder the welding operation.

After the above welding operation is completed, the hook at the tip of the shaft of the hammer type puller device is replaced with a fork type hook (H) in order to pull out the deepened portion of the streak-like concave portion using a hammer type puller device. However, as described above, since the welded bodies (3) have the same overall length and each of the welded bodies (3) can slide in the axial direction, the welded body (3) ) Is the part where the top is low, that is, the part where the streak-shaped recess is deep, and it is sufficient to directly pull out the welded body (3), and the welded body to be pulled out
The fork-shaped hook (H) of the hammer-type puller device is hooked on the hooking portion (34) of (3), and the individual drawers are drawn out according to the usual use of the hammer-type puller device. In this way, when the depth of the streak-like concave portion is adjusted to some extent, the hammer-type puller device is removed, and then the simultaneous pull-out is performed using a booster-type puller device.

In the simultaneous pull-out, the hook at the tip of the shaft of the booster type puller device is hooked to the hanging main ring (53) attached to the operation handle portion (5), and the simultaneous pull-out is performed based on a normal use. When this is done, the pull-out force acts on the upper flange (35) of the welded body (3) from the hanger plate (2), so that the streak-shaped concave portions can be pulled out all at once. In this process, the restoration surface is hit with a mallet or the like to perform correction, and smoothing is performed.

When the simultaneous pull-out is completed using the booster-type puller device, the booster-type puller device is removed from the restoration surface, and if necessary, the hammer-type puller device is used again, and the pull-out device is sufficiently pulled out in the same procedure as the pretreatment. Post-processing is performed to pull out the missing parts, but if not necessary, the drawing operation is terminated, and a turning force is applied to the hexagon nut-shaped part formed on the head terminal (33) of each welded body (3) using a spanner, etc. Then, the welding portion between the bit tip portion (41) and the automobile body is sequentially twisted off, and the pull plate hanger is removed from the automobile body. Subsequent smoothing operations are performed in the same manner as in the related art, and thus description thereof is omitted.

The pull plate hanger for sheet metal repair described above is not limited to the above-described embodiment, but may be used for a welding base (3).
No head terminal (33) on top of 1), e.g. bit (40)
Can be directly equipped with a head-shaped head terminal (33) that presses the electrode rod on a part of the bit, so that the bit tip (41) can be pressed against the welding surface during welding, in which case the bit (40)
If the welding base (31) is insulated, the insulator (38) interposed between the welded body (3) and the hanger plate (2) can be omitted.
Further, when the hooking portion (34) provided on the top of the welding base (31) has a ring shape or the like, the hammer-type puller device can be used even if the tip of the shaft has a normal hook shape.

Also, the insulator (38) may be fitted and fixed inside the through hole (21) of the hanger plate (2) without being integrated with the welding base (31). In addition to its trademark, it can maintain insulation against instantaneous large currents during welding, and can withstand heat generated by the flow of large currents and the impact of individual drawers. An existing material having both properties and impact resistance can be used. In addition, an elastic body (46) such as a spring or a rubber body is interposed between the lower flange (39) of the insulator (38) and the hanger plate (2) so as to buffer an impact at the time of individual pull-out or the like and to insulate the insulator. The damage of (38) may be prevented. In addition, it goes without saying that the dimensions of the hanger plate (2), the welded body (3) and the like should be changed as appropriate according to the portion to be repaired.
