Number spraying machine capable of achieving automatic switching between high number spraying speed and low number spraying speed and number spraying method thereof

Abstract

The invention provides a number spraying machine capable of achieving automatic switching between high number spraying speed and low number spraying speed and a number spraying method thereof. According to the technical scheme, the number spraying machine comprises two driving wheels arranged oppositely, a driving base arranged between the two driving wheels, a feeding structure and an operating platform arranged on a driving axle housing, and a cantilever arranged on the operating platform, wherein one end of the cantilever is arranged on a turntable seat controlled by a main machine of the operating platform, the other end of the cantilever is hinged with a power arm, and the end part of the power arm is provided with a number spraying mechanism; and the number spraying method comprisesthe following steps: 1, positioning, and 2, detecting and number spraying. The number spraying machine and the number spraying method thereof have the beneficial effects that after a high-pressure spray gun device is controlled by a control box to carry out multidirectional positioning on the number spraying position of a steel billet workpiece to be sprayed with numbers, the positioning data areaccurately detected through a grating sensor, the rate of missing detection of the number spraying mechanism is reduced, missing spraying of the number spraying machine is avoided accordingly, and thenumber spraying efficiency is improved; and the rapid number spraying function is added to the number spraying machine, and switching between high speed and low speed can be realized according to production requirements.

Description

technical field [0001] The invention relates to the technical field of billet number spraying equipment, in particular to a number spraying machine and a number spraying method capable of automatically switching between fast and slow speeds. Background technique [0002] The 1# furnace of the first workshop of electric furnace steelmaking produces 400 series rebar. The original numbering machine is used to spray numbers on the steel billets with a cross section of 16 meters long. It only takes one minute to finish the numbering. The machine sprays the year number, workshop number, flow number, number and furnace number on the cross-section of the billet. Due to the short process of the continuous casting machine, the current billet is cut into a cross-sectional length of 12 meters, which only takes 35-40 seconds Spraying can be finished within 1 minute. Because the speed of six machines and six streams is 3.0 m / min, the speed of the original spraying machine cannot keep up w...

[0002] The 1# furnace of the first workshop of electric furnace steelmaking produces 400 series rebar. The original numbering machine is used to spray numbers on the steel billets with a cross section of 16 meters long. It only takes one minute to finish the numbering. The machine sprays the year number, workshop number, flow number, number and furnace number on the cross-section of the billet. Due to the short process of the continuous casting machine, the current billet is cut into a cross-sectional length of 12 meters, which only takes 35-40 seconds Spraying can be finished within 1 minute. Because the speed of six machines and six streams is 3.0 m / min, the speed of the original spraying machine cannot keep up with the production rhythm, which often leads to serious stacking of billets on the cooling bed, which affects production. Operators often need to turn the spraying machine Stop working, the cooling bed area can operate normally

The steel billets without numbers need to be manually written by P4 operators, which increases the labor intensity of P4 workers, and the numbering rate of the numbering machine is also very low
