Metal sheet pickling device

Abstract

The invention relates to the field of machining of metal sheets, in particular to a metal sheet pickling device. The device comprises a pickling water tank, an injection component arranged in the pickling water tank and used for performing injection pickling on the both side surfaces of a metal sheet, a top spray component arranged above the pickling water tank and a discharging component arrangedat the downstream end of the pickling water tank. A guide plate allowing the bottom of the metal sheet to be capable of sliding towards the discharging component is arranged in the pickling water tank. A feeding component is arranged at the upstream end of the pickling water tank. A plurality of hollow bearing columns are arranged under the pickling water tank. The injection component comprises two flushing parts arranged on two sides inside the pickling water tank correspondingly. The injection ends of the two flushing parts are arranged oppositely, and angles of 130 degrees are formed between the injection direction of the two flushing parts and the sliding direction of the metal sheet. A discharging manipulator and a discharging electric cylinder are arranged at the downstream end of the pickling water tank. According to the metal sheet pickling device, injection pickling can be performed on the outer surface of the metal sheet comprehensively, no dead corner is present in the injection process, and quality requirements are also met on the premise that the output is increased.

Description

technical field [0001] The invention relates to the field of metal plate processing, in particular to a metal plate pickling device. Background technique [0002] The method of removing scale and rust on the surface of steel with an acid solution is called pickling. is a method of cleaning metal surfaces. It is usually carried out together with a pre-film, and the part is generally immersed in an aqueous solution such as sulfuric acid to remove films such as oxides on the metal surface. It is the pretreatment or intermediate treatment of electroplating, enamel, rolling and other processes. The pickling process mainly includes dipping pickling method, spray pickling method and acid paste rust removal method. The immersion pickling method is mainly to put the plate parts to be processed into the pickling water tank for a period of time, and the time is long. The overall efficiency of this method is slow. Compared with the spray pickling method, the output speed is faster, b...

Problems solved by technology

The dipping and pickling method is mainly to put the plate parts to be processed into the pickling water tank and soak them for a period of time. The overall efficiency of this method is slow. Compared with the jet pickling method, the output speed is faster, but the general jet pickling equipment is not comprehensive enough to spray the plate, and there are often some missing places that are not sprayed, which will affect the subsequent products. quality, leading to an increase in defective products
