[0002] In the current method, when the automobile sheet metal repair work is carried out, in order to make the concave surface flat, a sheet metal repair machine is generally used to weld a meson on the surface of the workpiece, and the meson is pulled out by external force to pull out the concave part. However, in actual operation, the pulled-out part is not flat, and each welded meson part will be higher than the original workpiece surface. In this way, a grinder is needed in the subsequent operation process to grind the raised part flat, but this grinding operation will make the sheet metal of the original raised part thinner, and even grind out leaks.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model; it should be noted that in this application, for the convenience of description, the "left side" in the current view is the "first end", the "right side" is the "second end", the "upper side" is the "first end", and the "lower side" is the "second end". The purpose of such description is to clearly express the technical solution, and it should not be understood as an improper limitation on the technical solution of this application.

[0032] The utility model aims to solve the technical problem that the protrusion of the welding workpiece meson needs to be mechanically polished in the prior art, which will cause the workpiece to become thinner. It provides an electric current sheet metal flattening tool, that is, it no longer uses mechanical polishing to flatten the protruding meson. The specific technical solution is, please refer to the attached Figure 1-4 As shown, the current type sheet metal ironing tool comprises: an insulating handle 10, which is constructed with a spherical front gripping end 101 and a rear bonding end 102 connected to the front gripping end 101, so that as a tool, it has a significant hand-held position, and the front gripping end 101 and the rear bonding end 102 arranged at the hand-held position are as shown in the attached Figure 1 The shown one is more suitable for human hand grasping;

[0033] Furthermore, a handle base 20 is connected below the insulating handle 10; the handle base 20 is detachably connected to a buffer plate 30 and a graphite plate 40 capable of thermal insulation through screws 410;

[0036] When the graphite plate 40 contacts the workpiece 1, the low-voltage DC power supply 60 discharges so that the contact point between the graphite plate 40 and the workpiece 1 is heated by resistance. After the DC power is turned on, the contact point between the graphite plate 40 and the surface of the workpiece 1 generates an extremely high temperature due to the principle of resistance heat. When it contacts the uneven sheet metal surface, it will first iron out the protrusions to achieve the purpose of flattening the sheet metal, so that the protruding points of the workpiece 1 soften and fall back to flatten the surface of the workpiece 1. The protruding points are the protruding mesons.

[0037] The advantage of this technical solution is that the protrusions of the meson are no longer ground mechanically, the metal meson is softened by heating with electric current, and the surface of the workpiece 1 can be flattened by manually applying pressure to achieve flatness.
