[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 ...

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.

Example Embodiment

[0028] Example 1
[0029] See Figure 1 to Figure 3 The technical solution provided by the present invention is a spraying machine that can automatically switch spraying numbers between fast and slow speed, which includes two driving wheels 1 arranged oppositely, a driving base 2 arranged between the two driving wheels 1, and The feeding structure 3 and the operating platform 4 provided on the drive axle housing 2, and the cantilever 5 provided on the operating platform 4, one end of the cantilever 5 is provided on a turntable controlled by the host of the operating platform 4 On the seat, the other end is hinged with a power arm 6, and the end of the power arm 6 is provided with a number spraying mechanism;
[0030] The number spraying machine also includes a control box arranged on the drive base. The feeding structure 3, the operating platform 4, the cantilever 5, the power arm 6 and the electronic control circuit of the number spraying mechanism are respectively connected to the control box Connect to form a control loop.
[0031] Specifically, the power arm 6 includes a telescopic arm 62, a hydraulic cylinder 61 provided at one end of the telescopic arm 62, and a piston rod of the hydraulic cylinder 61 is connected to the telescopic arm 62.
[0032] Specifically, the number spraying mechanism includes a turntable 7 arranged at the other end of the telescopic arm 62, a support seat 8 is arranged on the rotating seat of the turntable 7, and a spray head device 9 arranged on the support seat 8. And the spray head device 9 is also provided with a grating sensor, and the output end of the grating sensor is connected to the control end of the control box.
[0033] Specifically, the spray head device 9 includes a booster actuator 10 arranged on the support base 8, a power end drives the traction assembly 11 of the booster actuator 10, and a high-pressure spray gun device 12 arranged at the driving end of the traction assembly 11 .
[0034] Specifically, the power-assisted actuator 10 includes a fixed rod 100, a hollow guide sleeve 101, and a power-assisted actuator 102 hinged to the fixed rod 100 and the hollow guide sleeve 101, respectively; the power-assisted actuator 102 is a power-assisted rod that swings from side to side , The bottom of the booster rod is provided with a groove for accommodating the end of the fixed rod 100, and a middle section is provided with a fitting groove penetrating the high-pressure air pipe 103 of the traction assembly 11.
