Automatic flame cutting machine for square and round continuous casting billets

Abstract

The invention relates to an automatic flame cutting machine for square and round continuous casting billets. The automatic flame cutting machine comprises a cutting machine body, two pairs of synchronous clamp forceps installed on the cutting machine body, a cutting gun positioned between the two pairs of synchronous clamp forceps, and a cutting gun position fine-tuning device for adjusting an initial position of the cutting gun, wherein the synchronous clamp forceps are suitable for clamping the casting billets, the cutting gun is used for cutting off the casting billets, each pair of synchronous clamp forceps comprises an upper clamping arm connected with a driving part, a lower clamp used for clamping the casting billets and a rotating sleeve formed between the upper clamping arm and the lower clamp, and the rotating sleeve is installed on the cutting machine body, so that the synchronous clamp forceps can rotate and swing around a horizontal axis, the cutting gun is installed on a cutting gun arm, and the cutting gun arm is installed on the cutting machine body and can rotate and swing around the same horizontal axis of the synchronous clamp forceps. As the cutting gun and the synchronous clamp forceps of the automatic flame cutting machine can rotate and swing around the same horizontal axis, even if the casting billets deviate, the center of the cutting gun can be always at the edges of the casting billets when the cutting gun is preheated and starts to cut.

Description

technical field [0001] The invention relates to an automatic flame cutting machine for square and round billets, in particular to an automatic flame cutting machine for square and round continuous casting billets which are used for cutting square and round billets during straightening into required lengths. machine. Background technique [0002] Square and round billet automatic flame cutting machine is the main equipment at the rear of the square and round billet continuous casting machine, which is used to cut the running billet into the required length. When the casting slab reaches the cutting position, the synchronous clamp on the cutting machine clamps the casting slab, so that the cutting machine and the casting slab run synchronously, and the cutting torch of the cutting machine cuts the casting slab. [0003] Such as figure 1 As shown, the edge detection mechanism in the square and round billet continuous casting automatic flame cutting machine includes two synchr...

Problems solved by technology

[0010] At this time, the center line of the cutting torch is no longer at the edge of the slab, which will have a negative impact on the preheating of the slab, and may even cause accidents due to the inability to cut the slab
