Description

Technical Field

[0001] The invention relates to the field of steel cord manufacturing, and in particular to a steel cord pre-deformer with online detection capability. Background Art

[0002] Steel cord is the main skeleton material of radial tires. Steel cord is a special steel wire with high strength and toughness. It is usually made of high-quality carbon steel or alloy steel and undergoes multiple drawing, heat treatment and other fine processing processes to achieve the required dimensional accuracy and mechanical properties.

[0003] At present, the method for preparing and testing pre-deformed steel cord is to manually adjust the spacing of the pre-deformed gears on the wet pulling platform, test the steel wire, and then take samples for testing on the wave height detector. The detection principle is to magnify the projection of the steel wire through light, manually determine the plane and normal surface where the steel wire is located, and then perform calculations and measurements, and finally calculate the wave height, wavelength and other parameters. Then adjust the platform according to the test results, and then perform the above test until the target value is met before production.

[0004] This method requires manual work to continuously adjust the spacing of the deformed gears and then measure them. During the repeated adjustment process, large errors often occur, which prolongs the process and often takes a lot of time, affecting production. Summary of the invention

[0005] The present invention provides a steel wire pre-deformer with online detection, which detects the shape of the deformed wire online through laser, and through a series of signal analysis, detects the wavelength, wave height and other parameters of the deformed wire without human interference, and automatically, quickly and accurately adjusts the gear pressing amount according to the result, thereby improving the accuracy and adjustment efficiency of the steel wire.

[0006] The present invention is achieved through the following technical solutions: Compared with the prior art, the present invention has the following advantages: A steel wire pre-deformer with online detection, comprising: Base plate; A detection device, the detection device comprising two supporting plates arranged opposite to each other, a laser and a photoelectric sensor being fixed on the supporting plates respectively, and the laser and the photoelectric sensor being arranged opposite to each other; A steel wire pre-deformation device, the steel wire pre-deformation device comprises a gear support frame, a gear A, a gear B, and a gear shaft, the gear support frame is provided with a strip hole in the vertical direction, the gear A and the gear B are respectively rotatably connected to two gear shafts arranged in parallel in the horizontal direction, and the two ends of the gear shaft are respectively passed through the strip holes; an automatic adjustment device, the automatic adjustment device is provided with two groups respectively fixedly connected to the outside of the gear support frame, the automatic adjustment device comprises a motor, a screw rod, and a slider, one group of the automatic adjustment devices is provided with the motor arranged oppositely to the coaxial line, the motor is fixed on the gear support frame, the motor is provided with an output end fixedly connected to the screw rod, the slider is fixedly connected to the end of the gear shaft, and the screw rod is threadedly connected to the slider, Wherein, the detection device is arranged on the steel wire discharging direction of the steel wire pre-deformation device.

[0007] Furthermore, both ends of the gear shaft are respectively threadedly connected with shaft sleeves, and the sliding block is fixedly connected to the ends of the shaft sleeves.

[0008] Furthermore, the motor is fixedly connected to the outer side of the gear support frame through a fastening sleeve.

[0009] Furthermore, the gear A and the gear B are rotationally connected to the gear shaft via gears respectively.

[0010] Furthermore, the motor is a servo motor.

[0011] Furthermore, a limiter is arranged on the spiral rod.

[0012] Furthermore, the gear A and the gear B are meshed with each other.

[0013] The beneficial effects of the present invention are: A laser and a photoelectric sensor are arranged in front of the steel wire pre-deformer. After the steel wire is extruded by the pre-deformer, the laser irradiates the deformed steel wire. After the photoelectric sensor receives the light signal, it passes through the signal amplifier, waveform processor, central calculator, and display to finally calculate the wave height and wavelength of the pre-deformed wire, and then determines the difference between the test value and the target value, thereby driving the motor to operate, so that the spiral rod rotates, thereby driving the slider, and gear A and gear B move in opposite directions at the same time, so as to adjust the gap between gear A and gear B so that the extruded steel wire meets the requirements. This setting avoids the external force influence on the steel wire when intercepting the steel wire sample by the traditional method, and the measurement error caused by manually adjusting the plane and judging by naked eyes during the test, thereby realizing online high-precision testing while having the advantages of high adjustment accuracy and high efficiency.
