Multi-purpose roller system quick opening and roller exchange device of straightening machine

Abstract

A multi-purpose roller system quick opening and roller exchange device of a straightening machine relates to the technical field of steel and nonferrous metals. An oil cylinder fixing support is connected with a roller support, a frame inner guide rail is fixed on a memorial gateway of the frame, an idler wheel is connected with the roller support, a lower roller system is installed in the roller support, a quick-opening oil cylinder is connected with the roller support through a connection block by using a bolt, and a movable pad block is installed between the roller support and the oil cylinder fixing support, so that when the roller system works, the idler wheel on the roller system is not contacted with the frame inner guide rail; when a roller is changed, the quick-opening oil cylinder drives the roller system to move towards the guide rail to enable the idler wheel on the roller system to be contacted with the frame inner guide rail; a gap is left between a lower surface of the roller support and the quick-opening oil cylinder in both the roller exchange state and roller un-exchange state; an approach switch is installed on the frame through an approach switch support, and the approach switch is provided with an approach switch information transmitting plate. The multi-purpose roller system quick opening and roller exchange device is simple in structure, only uses the quick-opening oil cylinder to achieve the quick opening and roller exchange of the roller system, greatly reduces manufacture and using cost of equipment, is long in service life, and is smooth and rapid in a roller exchange process compared with an original structure.

Description

technical field [0001] The invention relates to the technical field of iron and steel and non-ferrous metals, in particular to a multi-purpose device for quick opening and changing rolls of straightening machine rolls used in metal plate and strip straightening equipment. Background technique [0002] As metal strip straightening equipment, multi-roll straightening machine and straightening machine are widely used in steel and non-ferrous metal industries. The quick opening of the roll set and the quick change of the roll set are essential for the multi-roll straightening machine and straightening machine when threading the belt and passing the weld seam. Its function is to improve work efficiency and maintain the stability and reliability of the rolling precision of the upper roller system; replace the worn or damaged straightening rollers with new or repaired straightening rollers (the replacement method is the overall replacement of the roller system) . Most of the curr...

Problems solved by technology

The disadvantage is that the roll system cannot be hoisted from the top, but can only be pulled out from the open gear on the operating side of the frame, so that the equipment must be equipped with a roll change stand, a roll change cylinder and a cylinder fixing bracket, etc. (generally four roll change cylinders and corresponding cylinder bracket)
