Steel strip horizontal automatic shot blasting production line

Abstract

The invention discloses a steel strip horizontal automatic shot blasting production line. The production line includes a steel strip unreeling device, a steel strip flattening device, a drying box, a cooling device and a rotary device, a dustproof device and a rolling device that connect several shot blasting sets. The devices achieve steel strip transfer through several driving rollers. The production line also includes at least two shot blasting sets in series connection, a gap of at least 30cm is arranged between the two shot blasting sets, and each shot blasting set consists of a closed box, a shot blasting box and a steel shot collection device. The broad side of steel strip is transferred vertically in the closed box. Several left nozzles and right nozzles are symmetrically arranged on the left side and right side of the closed box along the transmission direction of the steel strip. The shot blasting directions of the left nozzles and right nozzles in each group are opposite respectively. The steel strip shot blasting machine provided by the invention improves the efficiency and quality of steel strip shot blasting, and is convenient for timely maintenance and service in a treatment process.

Description

technical field [0001] The invention relates to the technical field of steel strip shot blasting, in particular to a steel strip horizontal automatic shot blasting production line. Background technique [0002] The existing steel belt shot blasting machine is mainly a vertical shot blasting machine. The advantages of the vertical shot blasting machine are: small space occupation, timely cleaning of the internal stress of the steel belt, improvement of the fatigue resistance of the workpiece, and an increase in the stress of the workpiece when it is painted. Paint adhesion, and ultimately achieve the purpose of improving the surface and internal quality of the workpiece. [0003] However, when the existing vertical shot blasting machine is used to process the steel strip, the surface of the steel strip is discolored, the internal stress of the steel strip is not concentrated, the fatigue resistance of the workpiece is poor, the adhesion of the paint is poor, and the surface a...

Problems solved by technology

[0003] However, when the steel strip is processed by the existing vertical shot blasting machine, the surface of the steel strip is discolored, the internal stress of the steel strip is not concentrated, the fatigue resistance of the workpiece is poor, the paint adhesion is poor, and the surface and internal quality of the workpiece are poor.

Because for the steel belt, it is characterized by slender continuous parts. It uses a vertical shot blasting machine to blast the steel belt during shot blasting. The quality of the steel belt obtained is poor, and the shot blasting effect is not good. The belt needs to be repeatedly bent and stretched, which also has a certain impact on the performance of the steel belt
