Metal spray marking plate special for cold and hot rolling

Abstract

The invention relates to a metal spray marking plate special for cold and hot rolling. The metal spray marking plate special for the cold and hot rolling comprises a number plate engraved with numbers, base plates and chain shaft components used for connecting adjacent base plates. Each base plate is a frame shaped like a Chinese character 'ri'. Reverse T-shaped through grooves and inner grooves oppositely formed inwards are formed in the two sides of each frame. Two sides of the number plate is inserted in two groove openings of the base plate. The chain shaft components comprise a double-row connecting shaft, groove seats and a mandril. The double-row connecting shaft is provided with a connecting portion. The middle segment of the mandril penetrates through the double-row connecting shaft. Two ends of the mandril are respectively penetrate through circular holes of the groove seats. An end head of the mandril is riveted on one groove seat. The groove seats are arranged in the reverse T-shaped through grooves of the base plate. The shape of the lower portion of each groove seat is matched with that of each through groove. The groove seats are capable of rotating around the mandril. The metal spray marking plate special for the cold and hot rolling can be cleaned by organic solution so as to be reused after using and therefore cost is effectively saved. Due to the fact that the metal spray marking plate spares a number imprinting process, spraying and coating work efficiency is improved and optimized.

Description

technical field [0001] The invention relates to a coil number spraying device for cold and hot rolled coils, in particular to a special metal number spraying plate for cold and hot rolled coils, which belongs to the technical field of coil number spraying for rolled coils. Background technique [0002] Coil number spraying for hot-rolled coils is the final process before the finished product is rolled into the warehouse. The existing method is to use the hollow A4 copy paper embossed by the cutting plotter as the number spraying board, and lay it flat on the inside of the steel coil for numbering. spraying. In this way, although the paper numbering board is easy to make and easy to operate, due to the difference in coil numbers, different steel coil numbers require different numbering boards. In this case, each numbering board can only be used once. ; Even for the same steel coil number, due to the influence of the paper texture, the paper will be deformed after spraying th...

AI Technical Summary

Problems solved by technology

Although the paper numbering board is easy to make and easy to operate, due to the difference in coil number, different steel coil numbers require different numbering boards. In this case, each numbering board can only be used once. ; Even for the same steel coil number, due to the influence of the paper texture, the paper will be deformed after spraying the number, and the sprayed number will also be deformed when it is used again, making it difficult to identify

Therefore, the consumption of paper materials is very large. According to statistics, the average monthly consumption of spraying boards is relatively large, accounting for 74% of the total material consumption.

And after the steel coil spraying operation, a large amount of highly polluting waste paper is produced, which seriously affects the working environment

In addition, the part where the number is sprayed is the inner surface of the steel coil close to the end face. When spraying the number, it is difficult to control the amount of spraying, and the paint is sprayed on the end face of the steel coil, which will cover the information on the end face of the steel coil and affect the appearance.
