Phosphating treatment device for split pin

Abstract

The invention provides a phosphating treatment device for a split pin. The phosphating treatment device comprises a phosphating tank and a liquid storage tank, wherein a drive motor is arranged on anupper cover of the liquid storage tank; the output end of the drive motor is connected to a stirring shaft in the liquid storage tank; a stirring blade is arranged on the stirring shaft; the inner wall of the liquid storage tank is provided with a heating coiled tube; the liquid storage tank communicates with the phosphating tank through a liquid inlet tube; a water pump is arranged on the liquidinlet tube; spraying tubes which communicate with the liquid inlet tube are arranged in the phosphating tank; the multiple spraying tubes are arranged along the height of the phosphating tank; the bottom of the phosphating tank communicates with the liquid storage tank through a liquid return tube; a valve is arranged on the liquid return valve; a filter screen is arranged in the liquid storage tank; a storage rack is arranged in the phosphating tank; the storage rack comprises a supporting rod and a plurality of layers of storage boxes; supporting plates are arranged at the lower sides of thestorage boxes; a connecting barrel is arranged on a supporting rod; the supporting plates are connected to the connecting barrel through threads; the upper end of the supporting rod is provided witha limiting plate; and the limiting plate supports the upper side of the phosphating tank. The device can perform uniform phosphating on the split pin, improves phosphating efficiency, and facilitatesplacing and collecting of workpieces.

Description

technical field [0001] The invention belongs to the field of cotter pin processing equipment, and in particular relates to a cotter pin phosphating treatment device. Background technique [0002] Phosphating is a commonly used metal surface treatment technology. Phosphating is a process in which a chemical or electrochemical reaction forms a phosphate chemical conversion film. The formed phosphate conversion film is called a phosphating film. The purpose of phosphating is mainly to provide protection for the base metal and prevent the metal from being corroded to a certain extent. frictional lubrication. During the processing of cotter pins, surface phosphating is required for anti-corrosion after the forming is completed, and because the cotter pin workpieces are small, it is difficult to collect and salvage them directly in the phosphating pool, and the accumulation of workpieces will also affect the phosphating quality of the workpieces and efficiency. In order to keep...

Problems solved by technology

During the processing of cotter pins, surface phosphating is required for anti-corrosion after the forming is completed, and because the cotter pin workpieces are small, it is difficult to collect and salvage them directly in the phosphating pool, and the accumulation of workpieces will also affect the phosphating quality of the workpieces and efficiency

In order to keep the phosphating temperature constant, the existing phosphating device adopts the method of adding hot water to increase the liquid temperature when the temperature of the phosphating solution is low, but this will reduce the concentration of the phosphating solution and affect the production of the enterprise. The phosphating solution is static, and the concentration is inconsistent during the phosphating process, resulting in uneven phosphating
