Automatic flame cutting machine synchronization mechanism of slab caster

Abstract

The invention discloses a synchronizing mechanism for a slab caster automatic flame cutting machine, which relates to a mechanical device consisting of a cylinder, a fulcrum hinged support, a compressing bracket made of water cooling rectangular steel pipes, and an electromagnetic valve. The mechanical device is characterized in that the cylinder is installed on a water cooling frame, one end of the compressing bracket is hinged with the rear part of a rear frame, and the other end is pushed by the cylinder to compress a casting blank, thus causing a cutting vehicle to run synchronously with the casting blank during the cutting so as to ensure the slot is perpendicular to the longitudinal axis of the casting blank. The mechanical device has the beneficial effects that the double stroke cylinder is specially designed according to pre-compression features, the pre-compressing stroke and a main compressing stroke replace the original common cylinder, and a pressure regulating valve in pneumatic control is cancelled. The synchronizing mechanism for the slab caster automatic flame cutting machine not only is convenient for field debugging, but also radically prevents the position of a pressure head from moving during the pre-compressing, thus fully exerting the effect of the pre-compressing and largely increasing the cutting scaling precision.

Description

Technical field: [0001] The invention relates to a mechanical device, in particular to a synchronous mechanism for an automatic flame cutting machine of a slab continuous casting machine. Background technique: [0002] The slab automatic flame cutting machine is the main equipment at the rear of the slab continuous casting machine. The slab is a key component to keep running synchronously. At present, in the synchronization mechanism of the automatic flame cutting machine of the original slab continuous casting machine, the pre-compression and main compaction actions are completed by ordinary cylinders, and the pneumatic control is composed of two two-position five-way solenoid valves and a pressure regulating valve. When the electromagnetic valve DT1 is energized, the pressing frame quickly drops to 30-50mm of the billet surface. When the electromagnetic valve DT1 is de-energized, the electromagnetic valve DT2 is energized, and the pressure regulating valve is adjusted to ...

Problems solved by technology

However, because the pre-compression head of this synchronous mechanism is in a suspended state, with the continuous change of the ambient temperature when the cutting machine is working, the gas pressure in the cylinder is also constantly changing, resulting in the erratic position of the pressure head, sometimes high and sometimes low

Therefore, the pre-compression effect of the synchronous mechanism is greatly weakened, or it does not work at all. This will not only increase the vibration of the machine during the main compression, but also reduce the cutting-to-length accuracy. The user's response is great, which directly affects the reputation.
