Coiling machine side guide plate with long service life

Abstract

The invention relates to a coiling machine side guide plate with long service life. The coiling machine side guide plate comprises a side guide plate body and an idler wheel assemblies, wherein the side guide plate body comprises a left side guide plate body and a right side guide plate body; a plurality of idler wheel assemblies are arranged on the inner sides of the side guide plate body; each of the idler wheel assemblies comprises an idler wheel, a rolling bearing, a penetrating cover and a sealing element; the upper ends of the rolling bearings of the idler wheel assemblies are assembledon a fixed chuck plate; the fixed chuck plate is fixed on the side guide plate body through a bolt; and lower ends of the rolling bearings of the idler wheel assemblies are mounted on a guide plate body lower plate. According to the coiling machine side guide plate, the idle wheels can rotate freely, and as the rolling friction coefficient of the idler wheels is small, the generated friction forceis small, scratch to two side faces of a steel strip and burr generation are greatly reduced, and product quality and productions stability are ensured; and in addition, as the friction force is lowered, the abrasion loss is reduced, onetime looming service life of the side guide plate is greatly prolonged, the changing frequency of the side guide plate is reduced, the operating efficiency of a production line is improved and the operating cost is lowered.

Description

technical field [0001] The invention relates to the field of coilers, in particular to a long-life coiler side guide plate. Background technique [0002] The front side guide plate of the hot rolling coiler has the functions of introducing, centering and clamping the strip steel. Stability during taking and good roll shape after roll forming. At present, a slide plate is installed on the side of the side guide plate of the coiler. When the side guide plate is centered and clamped to the strip steel, the slide plate contacts the two sides of the strip steel. The general material design of the slide plate is Q235, but due to its low hardness and quick wear, it needs to be replaced. Frequent, which affects the production rate; After the slide plate is off the machine, it is necessary to weld the worn groove or replace the slide plate, which requires a lot of maintenance and high cost; Although the grinding alloy material improves the service life, it is very easy to cause scr...

Problems solved by technology

At present, a slide plate is installed on the side of the side guide plate of the coiler. When the side guide plate is centered and clamped to the strip steel, the slide plate contacts the two sides of the strip steel. The general material design of the slide plate is Q235, but due to its low hardness and quick wear, it needs to be replaced. Frequent, which affects the production rate; After the slide plate is off the machine, it is necessary to weld the worn groove or replace the slide plate, which requires a lot of maintenance and high cost; Although the grinding alloy material improves the service life, it is very easy to cause scratches on both sides of the strip steel; the slide plate is used for a long time, it is prone to cracks, and particles will be generated, which are easy to enter the pinch roller and affect the product quality; the slide plate and the strip steel The contact is sliding friction. Because of the large friction force, it is easy to scratch the two sides of the strip, and it will affect the product quality and production stability in the next process of cold rolling production.
