Description

The sheet metal repair machine for the purpose of repairing and repairing the dents of sheet metal {THE RETURN AND REPAIR IMPLEMENT OF SHEET METAL'S DAMAGED SURFACE}

There are two types of work that can be done to repair or repair sheet metal parts that have been crushed in various forms: first, replacing the entire area to which the broken or crushed parts belong, or cutting the part and then joining it with new sheet metal to fit the part. There is a case of working, and secondly, most of the cases are applicable to this, using a spot welding machine to pull out the dents by welding. However, in this case, it is assumed that the electric power must be supplied to the site, and the volume of the welding machine is not small and the weight is at least 40-50 kg. I need a lot. In addition, there are many difficulties in working as close as possible to the work site, and there are inherent wires and other wires of the machine that are entangled, sparks from welding work, and various safety accidents and risks of fire. . In addition, accident prevention measures should be prepared for the creation of irrational work spaces, and other skilled technicians are required. As a result, there are many cases where repair or repair work on site is impossible. Most of these cases require additional work tools or devices. There is one other way. Although extremely limited in use, it is a device equipped with a suction plate using compressed air. However, this also requires an external compressed air supply line and creates an unreasonable work space, as well as spot welders, and in terms of repair and repair of various deformed sheet metals, greatly reduces efficiency, accuracy and coverage. The effect is also small enough to explain. However, the mechanism of the present invention eliminates these drawbacks at once.

As described and described above, the process of repairing or repairing the crushed sheet metal material, whether large or small, is not very different. However, unless the sheet metal material is largely broken or crushed, and the product must be completely renewed or completely replaced, the sheet metal repair machine of the present invention can be used for repairing and restoring sheet metal of an automobile interior and exterior vehicle body having abnormalities. The interior and exterior materials of covers and various box-type products of machinery, as well as the repair and repair of sheet metal exteriors or decorations of buildings and buildings, etc., can be widely applied. . In addition, it is very compact, so it is excellent in mobility and storage, and it is easy to exchange or replace tool according to the work situation and method. And as described above, it can be said to be a sheet metal repair machine that overcomes various inconveniences and limitations of the existing work, and there are no safety accidents or fire hazards that existed in the existing work methods. In addition, the method is very simple to use, which does not require specialized knowledge or skills, and is easy to disassemble and assemble, making it applicable to various works other than repairing and repairing crushed sheet metal.

Corresponds to

The structure of the three parts described above will be described in detail. The handle 1 of the handle portion is assembled in the form of a combination of female and male screws at the left end of the sliding shaft 4, and the handle 1 is formed on the shaft 4. In order to fix it securely), the shaft 4 is engaged with the female and male screws in the form of a female and male screw, and a tightening screw 10 is used as shown in the sectional view of FIG. This part can also be fixed by the method of injection molding the handle 1 with respect to the shaft 4 in order to reduce manufacturing cost and a manufacturing process. And the auxiliary handle 12 in the handle (1) is to use the present invention to repair or repair the crushed sheet metal parts by turning the tool (Tool) as shown in the <b> of Figure 8 or It is designed for convenience such as easy to hang when storing or mounting the device. And the hammer stopper 2 is designed to generate the hammering force and is firmly fixed to the sliding axis 4.

Next, the sliding hammer (Hammer) and the axis (Axix Pole) portion of the hammer (3) has a hole in the center to slide the diameter of the sliding rod (4). This part is a part that applies the tool parts (5, 6, 7) to the crushed sheet metal part, and then generates a force for recovery of the crushed part, along the weight of the sliding hammer (3) and the shaft (4). The magnitude of the force is determined by the speed of the sliding hammer (3), and the action of the force is handled (1, 12), shaft (4) and tooling (5, 6) except the hammer (3). , 7, 8, and stopped by the stopper 2 is integrated with (14, 15, 16 of Fig. 9) while generating another force, that is, a hitting force. This inertia is powered to repair or repair the crushed sheet metal as shown in FIG. However, since the sheet metal is thick or requires a lot of force depending on other working conditions and conditions, it is necessary to increase the weight of the hammer (3), so the additional mounting portion to mount the additional weight (13) (11) is designed and the tip of this part is screwed. This is to make it easy to mount the additional weight 13 to the hammer 3, as shown in [3] and [6], and to easily fix the mounted weight 13 to the hammer 3 A nut 9 was placed on the threaded portion of the tooth 11. .

The following is a tooling (Tooling) part, the present invention was designed so that the tool can be replaced or replaced in various ways depending on the degree of distortion or the state of the sheet metal, working conditions and the like. 7 shows the tooling portion in an enlarged cross-sectional view. In this figure, the main body 5 of the tool detachment is screwed to the sliding rod 4, and the fixing nut (8 in Figure 2) to prevent loosening to securely assemble it. In FIG. 7, reference numeral 7 denotes an arbitrary screw that can be used as any screw such as a countersunk head screw or a round head screw. The heads of these arbitrary screws 7 are fixed by pushing and tightening the main body 5 of the tool detachment with the screw fixing cap 6. Its reference is also shown as an assembled form in (R) of FIG. 9. Next, the drawings in (R) and (S) of FIG. 9 illustrate that the various tools can be applied depending on the state and working conditions of the crushed sheet metal while performing various tooling operations. For example, as shown in the picture of [Fig. 9] to insert a bolt-shaped tool 14 in place of the existing screw (7) and various shapes, that is 'a' type, 'c' type, 'circle' 'Type ... can be used to combine the tools, etc., but here the application of the combination of the circular tool 16, then tightened with a fixing bolt 15 or a fixing pin. In this case, however, it is not unreasonable to use a small force of inertia, but it is not unreasonable when a relatively large force is required. Therefore, various tools may be directly welded to the fixed cap 6 of the tool, or may be directly assembled to the main body 5 of the tool detachment by fabricating the integrated tool.

Finally, the basic effects of the sheet metal repair or repair operations of the sheet metal repair or repair work of the present invention will be described. The effects of the present invention will be described. As shown in the picture. Specifically, a small hole is drilled in a random place P with a sharp punch or a fine drill in the sheet metal part 17 that is crushed in the step of <a> in FIG. 8, and is shown in <b> in FIG. As shown in the drawing, the handles 1 and 12 are screwed one to two times with the screw 7 at the end of the tool 5, 6, 7 of the present invention into the hole. In this case, the sheet metal 17 is inserted into the thread of the screw 7. Then, with one hand, the handle part is supported, and with the other hand, the sliding hammer 3 is lightly sent in the 'Y' direction of [FIG. 2] and [FIG. 4], and then the backward motion is performed in the 'X' direction. At this time, the momentum is generated by the hammer stopper 2 of [FIG. 1], [FIG. 2], [FIG. 3] while the hammer 3 stops, and the force is < The sheet metal is repaired or repaired. As described above with reference to the example of [9], the present invention can be used by applying a variety of tools in a variety of forms, and also made in a variety of ultra-small, small, medium, large, etc. for any crushed sheet metal in any case Recovery or repair work is possible. And small scratches caused by tools such as holes are a secondary problem, but they can be covered with hardeners for post-treatment, embellished with stickers, or many other ways to finish the area in a flash. Above all, the present invention is a case in which crushing occurs in various products using various sheet metal materials, namely, exterior materials of covers and various boxes of interior and exterior vehicles or various machinery of automobiles, furthermore, buildings or other It is possible to repair or repair the crushed sheet metal easily and simply by the machine itself of the present invention without any external power source even when the sheet metal exterior or decorative material crushing inside and outside the building.
