Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to an automatic conveying butt welding machine. Background Art

[0002] Butt welding machine is a kind of equipment specially used for butt welding. It heats two metal workpieces in relative positions to a plastic state or a molten state, and then applies a certain pressure to make them tightly combined, so as to achieve the connection between the workpieces. The working principle of the butt welding machine is based on the principle of arc melting metal or the principle of resistance heat. Under the action of the arc, or when the resistance between the contact surfaces of the workpieces passes through a low voltage and a large current instantly, the metal parts to be welded are melted and fused together. During the welding process, the arc generated by the electrode (or using resistance heat) melts the metal parts to be welded to produce a molten pool. As the electrode moves or the current continues, the molten pool cools and solidifies, and the metal parts are welded together. Butt welding machines are widely used in the connection of metal materials, especially in the production process of metal products such as steel bars, wires, cables, rails, pipes, etc. Flash butt welding is widely used in welding various plates, pipes, profiles, solid parts, tools, etc. It is an economical and efficient welding method.

When the welding is completed, the connecting rod 20 moves upward, driving the connecting frame 25 to move upward, so that the telescopic rod 27 is extended, and driving the top block 43 at the top of the telescopic rod 27 to move upward to the top of the opening 26. At this time, the demoulding groove 44 at the top of the top block 43 contacts the welded workpiece 24, and an upward thrust is generated on the workpiece 24, so that the workpiece 24 is separated from the loading platform 16. After the workpiece 24 is separated from the loading platform 16, it moves to the bottom of the demoulding groove 44 until it flows into the unloading chute 45 along the guide plate 46, thereby realizing synchronous demoulding of the processed workpiece 24, avoiding burns to workers during manual demoulding, and improving the safety of welding; after the welded workpiece 24 enters the unloading chute 45, it falls into the storage chute below, thereby realizing automatic collection of it, which is convenient for centralized processing. By providing a diverter plate 48, the workpiece 24 can be neatly arranged inside the storage chute to avoid blockage.

[0033] When the rotating disk 8 rotates, the driving bevel gear 29 is driven to rotate through the first transmission chain 30 meshing with it. When the driving bevel gear 29 rotates, it drives the driven bevel gear 31 meshing with it to start rotating. When the driven bevel gear 31 rotates, it drives the driving wheel 33 to start rotating through the transverse shaft 32. When the driving wheel 33 rotates, it drives the driven wheel 35 to start rotating through the second transmission chain 34 meshing with it. When the driven wheel 35 rotates, it drives the cleaning shaft to start rotating. When the cleaning shaft rotates, it drives the outer sleeve 39 in the middle to start rotating, so that the blade 40 starts to rotate accordingly. When the blade 40 rotates, suction is generated to suck the smoke generated during welding into the interior of the dust suction cylinder 37, and it is filtered through the filter screen 41, so that the smoke generated during welding can be collected and processed to avoid it from polluting the air. When the cleaning shaft rotates, it drives the cleaning brush 42 at its right end to start rotating, so that the cleaning brush 42 cleans the smoke on the surface of the filter screen 41 to avoid the filter screen 41 being blocked.

[0034] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
