Problems solved by technology
Therefore, in the rolling process of section steel products, the waste of corners and scraps due to the trimming of both ends of the billet is huge, and each section of billet entering and exiting the roll will have an impact on the rolling mill, which not only increases the impact on the machine. equipment damage, and reduces the stability of steel rolling, and the phenomenon of steel blocking caused by the impact rolling mill at the end of the billet occurs from time to time

Embodiment
[0033] The billet automatic flash butt welding machine of the present invention flash-welds the red-hot billet during the rolling process of the steel billet, and welds each section of the billet into an infinitely long integral billet, so that the continuous rolling of the steel billet can be realized.
[0034] From figure 1 As can be seen, the present invention includes flash butt welding machine, deburring machine 3, running gear; running gear includes walking trolley 4, telescopic bracket 5 (see Figure 6 ~ Figure 8 ); the walking trolley 4 comprises a vehicle frame 35, a motor 37 and a transmission mechanism 36, the motor 37 and the transmission mechanism 36 (ie gearbox) are assembled at one end of the vehicle frame 35, and the power output shaft of the motor 37 is connected and drives the wheels through the transmission mechanism 36; The whole welding process of the steel billet is carried out during the steel rolling movement. The function of the walking trolley 4 is to...

The invention relates to the technical field of automatic welding equipment, in particular to an automatic flash-butt-welding machine for a steel billet. In the steel rolling production, the steel billet is divided into sections due to the limit by equipment and conditions, two ends of each section of steel billet need to be shaped, so that waste is caused, and impact is caused when each section of steel billet gets in and out of a rolling mill. The automatic flash-butt-welding machine for the steel billet comprises a flash-butt-welding machine body, a burr sweeper, a travelling trolley and telescopic brackets; the flash-butt-welding machine body and the burr sweeper are arranged on the travelling trolley, and the burr sweeper is positioned between a movable rack and a fixed rack of the flash-butt-welding machine body; the front part and the back part of the travelling trolley are hinged to one telescopic bracket respectively; the travelling trolley drives the flash-butt-welding machine body and burr sweeper to reciprocate in a working area along steel rails on the ground, so the steel billet can be welded; the telescopic brackets support the travelling suspended steel billet. In the section steel rolling process, the sectioned steel billets are welded to form a whole steel billet, continuous rolling of section steel products can be realized, the production efficiency is improved, the production cost is reduced, equipment damage is avoided.
Description
technical field [0001] The invention relates to the technical field of automatic welding equipment, in particular to an automatic flash butt welding machine for steel billets, which is used for automatic welding of square steel billets with a size greater than 60×60 in a steel rolling production line. Background technique [0002] In steel rolling production, due to the limitation of equipment performance and production conditions, steel billets are always rolled in the form of cut-to-length steel products. cut off. Therefore, in the rolling process of section steel products, the waste of corner waste generated by cutting the head and tail of the two ends of the billet is huge, and each section of billet entering and exiting the roll will have an impact on the rolling mill, which not only increases the impact on the machine. The equipment is damaged, and the stability of steel rolling is reduced, and the steel blocking phenomenon caused by the impact rolling mill at the end...
