Description

Technical Field

[0001] This utility model belongs to the field of strip production technology, specifically relating to a cleaning device for a rolling mill swing frame. Background Technology

[0002] Due to their compact structure and limited space, the inlet and outlet swing frames of the rolling mill cannot accommodate fixed cleaning devices. During production, emulsion (coolant) easily adheres to the lower surface of the swing frame. If not cleaned regularly or if cleaning is poor or inadequate, the emulsion will saponify and form a black, highly adhesive sludge. This sludge falls onto the product surface during rolling, easily causing various defects and severely affecting product quality. Currently, cleaning of these swing frames mostly relies on manual rinsing, which suffers from low cleaning efficiency, poor cleaning quality, and high operational risks. Utility Model Content

[0003] The purpose of this invention is to provide a mill swing frame cleaning device to solve the problems of low cleaning efficiency, poor cleaning quality, and high cleaning operation risks associated with the existing manual rinsing of mill swing frames.

[0004] This utility model provides a mill swing frame cleaning device, including an installation component, a lifting component, a guiding component, and a cleaning component;

[0005] The lifting assembly includes a cylinder;

[0006] The cylinder is vertically fixed on the mounting assembly, with the output end of the cylinder facing upwards.

[0007] The guiding assembly includes a guide cylinder and a guide rod;

[0008] The guide cylinder is vertically fixed on the mounting assembly;

[0009] The guide rod is vertically inserted into the guide cylinder, with its upper end extending vertically upward. The upper end of the guide rod is fixedly connected to the output end of the cylinder, and the guide rod can move up and down along the guide cylinder under the drive of the cylinder.

[0010] The cleaning assembly includes a rotating nozzle;

[0011] The rotating nozzle is fixedly connected to the guide rod.
