[0002] Steel strip refers to a conveyor belt made of carbon steel that serves as the traction and carrying component of a belt conveyor. It is a narrow, long steel plate produced by various steel rolling mills to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Steel strip is divided into two categories based on the material used: ordinary steel strip and high-quality steel strip. Existing industrial steel forming machines generally use a shearing mechanism on board to shear the steel strip to obtain a long steel strip of a certain width. The existing publication number is: CN111250922B. A welding auxiliary equipment with a reasonable structural design and simple operation includes a frame, and two fixed plates for fixing materials for welding are rotatably provided on the frame. The fixed plates are provided with a plurality of arc grooves that are consistent with the diameter of commonly used round tubes. The center lines of the plurality of arc grooves are located on the same vertical plane, and the arc grooves are opened downward in descending order from large to small diameter. The fixed plates are provided with a plurality of right-angle grooves that are consistent with the width of commonly used square tubes perpendicular to the arc grooves. The center lines of the right-angle grooves are located on the same vertical plane, and the opening widths of the right-angle grooves are opened downward in descending order from large to small. The frame is provided with a first adjusting device for adjusting the distance between the two fixed plates, a second adjusting device for respectively adjusting the height of the two fixed plates, and a control device for controlling the fixed plates to stop rotating at any angle. The existing welding auxiliary devices mainly have the following disadvantages: Due to the poor rigidity and dimensional stability of steel strips, it is very easy to have problems such as misalignment and uneven gaps when welding them. Summary of the Invention

[0003] The object of the present invention is to provide a welding auxiliary device for the production of high-temperature alloy ultra-thin steel strips to solve the problems raised in the above background technology.

[0014] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0015] Reference Figure 1-2 As shown in Figures 6-7, a welding auxiliary device for producing ultra-thin high-temperature alloy steel strips comprises a base 1, a conveying mechanism 2 is connected to the base 1, and a limiting mechanism 3 is fixedly connected to the conveying mechanism 2; The conveying mechanism 2 includes: An active component 21, the active component 21 is connected to the base 1, and a plurality of reciprocating swing components 22 are fixedly connected to the active component 21; and The limiting mechanism 3 includes: The pressure plate assembly 31 is connected to the active assembly 21 , and a transmission assembly 32 is slidably connected to the pressure plate assembly 31 .

[0016] When welding the steel strip, place one end of the steel strip for welding on the active component 21, and use the reciprocating swing component 22 to drag one end of the steel strip to rotate to the highest point. At this time, the end of the other steel strip to be welded is at the highest point at the same time. When the welded ends of the two steel strips move toward the highest point at the same time, the pressure plate component 31 moves downward at the same time to limit the steel strip. When the steel strip moves to the highest point, the pressure plate component 31 just presses the welded end of the steel strip.

[0017] Reference Figure 5 As shown, the active component 21 includes: Two driving shafts 211 are rotatably connected to the upper surface of the base 1. The two driving shafts 211 are mirror-imaged with respect to the upper surface of the base 1. Semicircular slide rails 212 are respectively provided at both ends of the two driving shafts 211. The semicircular slide rails 212 are arranged on the opposite side of the two driving shafts 211, and the semicircular slide rails 212 are fixedly connected to the upper surface of the base 1.

[0018] The reciprocating swing assembly 22 is driven to rotate by the rotation of the two driving shafts 211. The driving shaft 211 is concentrically arranged with the semicircular slide rail 212. The two driving shafts 211 rotate in opposite directions. When the driving shaft 211 rotates, the reciprocating swing assembly 22 is driven to rotate, so that the welded end of the steel strip slides toward the highest point along the semicircular slide rail 212.

[0019] Reference Figure 3-4 As shown, several of the reciprocating swing components 22 include: The connecting block 221 is fixedly connected to the driving shaft 211, and an electric push rod 222 is fixedly connected to the connecting block 221. The output end of the electric push rod 222 is fixedly connected to a piston 223. The piston 223 is slidably connected in the piston cylinder 224. The piston cylinder 224 is fixedly connected to the connecting block 221, and one end of the piston cylinder 224 is fixedly connected to the suction cup 225.

[0020] Before welding, the suction cup 225 is attached to the surface of the steel strip. The electric push rod 222 contracts, which reduces the air pressure in the piston cylinder 224. Under the action of atmospheric pressure, the steel strip is adsorbed by the suction cup 225. Then, the driving shaft 211 rotates to drive the entire reciprocating swing assembly 22 to rotate, dragging the steel strip to slide along the semicircular slide rail 212 to the highest point.

[0021] Reference Figure 9-10 As shown, the pressing plate assembly 31 includes: The lower plate 311 has two sides fixedly connected to the upper ends of the two semicircular slide rails 212 respectively. The lower surface of the lower plate 311 is fixedly connected with a condensation pipe 312. The upper end of the lower plate 311 is provided with a pressing plate 313, and a welding port 314 is opened on the pressing plate 313.

[0022] When the steel strip moves to the highest point, the pressure plate 313 moves downward. When the steel strip moves to the lower plate 311, the welded ends of the two steel strips are facing each other. The pressure plate 313 presses the two steel strips tightly and welds the two steel strips through the welding port 314. The high temperature generated during welding is cooled through the condensation pipe 312.

[0023] Reference Figure 8 As shown, the transmission assembly 32 includes: Four gears 321, the four gears 321 are fixedly connected to the two ends of the two driving shafts 211 respectively, the four gears 321 are meshed with four racks 322 respectively, the upper ends of the two racks 322 at the same end of the four racks 322 are fixedly connected to the two sides of the U-shaped rod 323 respectively, the U-shaped rod 323 is slidably connected to the lower plate 311, the U-shaped rod 323 is provided with a spring 324, the upper end of the U-shaped rod 323 is fixedly connected to the lower end of the pressure plate 313, and one end of one of the driving shafts 211 is fixedly connected to the output end of the motor 325.

[0024] The motor 325 rotates to drive the driving shaft 211 to rotate, thereby driving the steel belt to move to the highest point, driving the gear 321 to rotate, and through the meshing action of the gear 321 and the rack 322, the rack 322 moves downward, and at the same time drives the U-shaped rod 323 to move downward, thereby driving the pressure plate 313 to move downward.
