[0002] Steel plate is a flat section steel material with a large ratio of width to thickness. The so-called plate usually refers to the product that is cut into a fixed length. According to the thickness, steel plates can be roughly divided into three categories: medium and thick plates, thin plates and foils. It is generally believed that plates with a thickness of 0.2 mm to 4.0 mm belong to the thin plate category; plates with a thickness of more than 4.0 mm are classified as medium and thick plates; and plates with a thickness of less than 0.2 mm are generally regarded as foils.

[0020] The present invention has the following beneficial effects:

[0021] The present invention places the thin plate into the interior of the welding frame, starts the hydraulic rod to push the limiting frame to move downward, and after the motor is energized, the motor drives the threaded rod to rotate inside the limiting frame, and pushes the welder to move inside the limiting frame during rotation, so that the welder can perform welding processing on the thin plate. When the top plate moves downward, it will push the extrusion component to move downward, and the extrusion component is used to press and fix the thin plate downward, thereby improving the stability of the thin plate during welding. When the extrusion component moves downward, it pushes one end of the merging component to approach each other inside the welding frame, and when the merging component moves, it pushes the thin plate to move inside the welding frame and contact each other, thereby improving the convenience of clamping the thin plate during welding processing. When the merging component moves, it will push the alignment component to move toward the center of the welding frame, and when it moves, it will squeeze the welding point of the thin plate, thereby avoiding the situation that the thin plate is misaligned during welding. The thin plate is placed inside the welding frame, and the downward movement of the limiting frame can clamp and fix the thin plate, thereby improving the welding efficiency of the thin plate.

[0022] When the top plate of the present invention moves downward, the synchronous plate pushes the lifting plate to move downward. When the lifting plate moves downward, the rectangular frame pushes the round rod to move downward. When the round rod moves downward, the pressure frame pushes the rolling rod to squeeze and fix the thin plate, thereby improving the stability of the thin plate during welding and avoiding the warping of the welding part of the thin plate. When the round rod moves upward, it squeezes the spring to contract, and the pressure of the spring is used to squeeze the thin plate, which can also improve the convenience of the thin plate during welding clamping.

[0023] When the synchronous plate of the present invention moves downward, it pushes the elastic rod to move through the connecting frame, and the elastic rod pushes the shrinking frame to slide on the surface of the positioning slide when moving. When the shrinking frame moves, it pushes the slide frame to move through the connection between the bent plate and the supporting frame, and the slide frame slides on the surface of the slide through the connection between the cylindrical rod and the sliding frame. When moving, the cylindrical rod pushes the thin plate to move on the bottom of the inner wall of the welding frame through the merging plate, so that the thin plates can be merged inside the welding frame, thereby improving the convenience of the thin plates during welding. When the synchronous plate moves downward, it pushes the supporting frame to move downward through the elastic rod, and when the supporting frame moves downward, the thin plates are squeezed and fixed by the pressing plate, thereby improving the stability of the thin plates when merging, and further improving the convenience of the thin plates during welding and installation.

[0024] When the telescopic frame of the present invention moves, the telescopic frame is pushed to shrink by the linkage plate, and the telescopic frame will push the movable frame to deform when shrinking. After the telescopic frame is retracted to the extreme end, the end of the thin plate away from the merging plate will move to the end where the alignment plates are close to each other. When the telescopic frame pushes the semicircular frame to move, the semicircular frame will squeeze the cylindrical pressure rod and shrink. When the semicircular frame shrinks, it pushes the force-bearing frame to move closer to each other through the telescopic rod. When the force-bearing frame moves, it pushes the alignment plate to squeeze the thin plate through the mobile frame, so as to avoid misalignment of the thin plate during welding. When the semicircular frame shrinks, it pushes the center frame to move on the surface of the bottom plate, so as to improve the stability of the semicircular frame when working.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
