Automatic grinding device for inspection of band steel

Abstract

The invention relates to an automatic grinding device used for strip test. A vertical guide and a guide base are arranged on the ground. A frame is arranged on the vertical guide. The frame is driven by a vertical servo motor and moves on the vertical guide. An upper transverse guide and a lower transverse guide are arranged on the frame. Two transverse mobile cars are respectively arranged on the upper transverse guide and the lower transverse guide. The transverse mobile cars are connected with the guides in a meshing way by gears and racks and are driven by a transverse servo motor to synchronously drag the grinding device to move transversely. A grinding head combination is combined with the upper transverse mobile car and the lower transverse mobile car by the linkage with a cylinder. An upper grinding head and a lower grinding head simultaneously pressurize on the upper side and the lower side of a steel strip and grind synchronously. By changing the prior artificial grinding mode into an automatic mode, the invention improves the effectiveness, the safety and the reliability of the strip surface quality test process, and eliminates the phenomena of quality error, grinding omission and test omission of artificial grinding, thereby saving manpower, time and material consumption and initial investment.

Description

technical field [0001] The invention relates to strip steel inspection in metallurgical manufacturing industry, relates to continuous annealing, hot-dip galvanizing and electro-galvanizing unit strip surface quality inspection technology, in particular to an automatic grinding device for strip steel inspection. Background technique [0002] At present, in the continuous annealing, hot-dip galvanizing and electro-galvanizing automobile sheet production lines at home and abroad, in order to check the quality of the strip steel surface, the surface of the strip steel is generally ground back and forth vertically and horizontally at the exit inspection table with abrasive materials such as manual hand-held oil stones. Through grinding, various defects such as vibration marks on the surface of the steel plate, the depth of scratch defects, the depth of foreign matter intrusion, various roll marks, wide and narrow marks, and creases are inspected. According to the field survey, th...

AI Technical Summary

Problems solved by technology

[0003] 1. Manual grinding is uneven and the grinding quality is unstable

Due to the differences in the height and strength of each person during the manual grinding process, and the grinding force is also difficult to master, resulting in differences in the surface uniformity of the ground steel plate, resulting in deviations in the quality inspection personnel's judgment on the quality defects of the steel plate. It even happens that existing defects are missed, which is easy to cause quality problems

[0004] 2. Manual grinding requires several people to operate at the same time, and many people are employed.

[0005] 3. Only one side of the strip steel can be ground manually, and the other side of the strip steel that has not been ground will not be able to objectively show defects during the next process inspection, resulting in missed inspections

Due to the huge difference and mismatch of current technical means in strip surface grinding and testing, the advanced strip surface defect detector (CCD) used in the subsequent process cannot play the function of detecting and recording both sides of the strip, so that its function cannot be fully exerted come out

[0006] 4. There are potential safety hazards in manual grinding

During manual grinding, because the human body is close to the steel strip, the operator needs to lean over to grind on the steel strip. The edge of the steel strip is relatively sharp, which may easily cause personal injury
