Description

Technical Field

[0001] The invention relates to an ultra-thin steel strip polishing and grinding abrasive belt grinding main machine and a control method for a steel strip with a thickness of 0.01mm-0.7mm, belonging to the field of ultra-thin steel strip polishing and grinding control methods. Background Art

[0002] Conventional steel belt grinding is a high-speed rotating belt head that grinds the steel belt surface. The back side of the belt head that contacts the steel belt is the grinding support roller. The steel belt to be ground is between the support roller and the belt head. The belt can grind the steel belt surface only with the strong support of the support roller. However, when grinding ultra-thin steel belts with a thickness of 0.01mm to 0.7mm, the conventional belt head is used to support the steel plate to be ground. When grinding ultra-thin steel belts with a thickness of 0.01mm to 0.7mm, if there is a support roller, the support roller and the belt head form a line contact with the steel plate to be ground. Therefore, when the support roller supports the ultra-thin steel belt grinding, the belt will directly wear through the steel belt, and the surface of the steel belt cannot be ground. Summary of the invention

[0003] Design purpose: To avoid the shortcomings of the background technology, an ultra-thin steel belt polishing and grinding abrasive belt grinding main machine and control method are designed, which can complete the surface grinding of the ultra-thin steel belt without the support of support rollers and will not cause the abrasive belt to directly wear through the ultra-thin steel belt.

[0004] Design scheme: In order to achieve the above design objectives. The present invention has a design scheme: based on the existing background technology, under the tension of the adjustable spring roller, the sanding belt head, spring roller and pressure roller are used to make the steel belt produce a certain angle of wrap at the sanding belt head, so that the sanding belt changes the line contact with the surface of the steel belt to the surface contact, thereby achieving the grinding effect of the ultra-thin steel belt.

[0005] The grinding of ultra-thin steel strips mainly involves the research and development of the main machine of the abrasive belt grinder, and the main machine of the abrasive belt grinder consists of the following components: a lower bed frame, an abrasive belt head, a conveying roller, and a pressure roller. Based on the above-mentioned main machine of the abrasive belt grinder, the present invention sets a bouncing roller in front of or behind the abrasive belt head of the main machine of the abrasive belt grinder. The bouncing roller and the pressure roller in the abrasive belt head work together to force the ultra-thin steel strip being ground to form an elastic wrap angle α polishing with the abrasive belt (i.e., forming surface grinding of the steel strip). Due to the elastic structure of the bouncing roller, the elastic wrap angle polishing can not only cooperate with the abrasive belt head to force the ultra-thin steel strip being ground to form surface contact polishing with the abrasive belt, but also fundamentally solve the defects of the background technology.

[0006] The support roller and the bouncing roller can move up and down respectively. The purpose of this design is to properly fine-tune the angle of the wrap angle α to achieve the best effect.

[0007] The structure of the bouncing roller: The bouncing roller is installed on the conveying roller frame and can be raised and lowered together with the conveying roller frame as a whole. At the same time, the bouncing roller can also be raised and lowered by itself. When the bouncing roller rises, the highest point of the bouncing roller is higher than the highest point of the supporting roller, so the ultra-thin steel belt can be polished; when the bouncing roller descends, the highest point of the bouncing roller is lower than the highest point of the supporting roller, so the surface of the thick steel belt can be ground with the support of the supporting roller.

[0008] Technical Solution 1: A belt grinding main machine for polishing and grinding ultra-thin steel belts, comprising a belt grinding main machine, wherein a bouncing roller is arranged in front of or behind the belt head of the belt grinding main machine, and the bouncing roller can also rise or fall by itself. When the highest point of the bouncing roller is higher than the highest point of the supporting roller, the ultra-thin steel belt is polished; when the highest point of the bouncing roller is lower than the highest point of the supporting roller, the surface of the thick steel belt is ground under the support of the supporting roller.

[0009] Technical Solution 2: A control method for polishing of an ultra-thin steel belt, comprising a belt grinding main machine, wherein a bouncing roller is arranged in front of or behind a belt head of the belt grinding main machine, and the bouncing roller works together with a pressure roller in the belt head to force an elastic wrap angle α to be formed between the ultra-thin steel belt being ground and the sanding belt for polishing, and the elastic wrap angle α for polishing forces the ultra-thin steel belt being polished to form surface contact polishing with the sanding belt.

[0010] Compared with the background technology, the present invention solves the problem that the existing belt grinding machine directly grinds through the steel belt with a thickness of 0.01mm to 0.7mm, which often causes the steel belt to be directly worn through; secondly, it has a simple structure, low manufacturing cost, and high practical value, solving the technical problems existing in the background technology.
