Cleaning method and cleaning device for brazing filler metal extruded wire

Abstract

The invention relates to a cleaning method for a brazing filler metal extruded wire. The cleaning method comprises the following steps of: 1) soaking a coiled extruded wire in an acidic solution in which the mass percent concentration of an acid ranges from 15% to 20% for 15-30 minutes, thus removing scale cinders; 2) performing vibrating flushing for 10-30 seconds to remove residues from the surface of the extruded wire; 3) flushing for 5-10 seconds to further remove residues from the surface of the brazing filler metal; 4) soaking the extruded wire in a passivation solution containing 0.3-0.8% of benzotriazole at 50-70 DEG C for 1-5 seconds. The invention also relates to a cleaning device for implementing the cleaning method. The cleaning device comprises a frame platform, tanks and a conveying device; and the cleaning device is characterized in that the tanks include a deoxidation tank, a vibrating flushing tank, a flushing tank and a passivation tank which are orderly arranged, the tanks are located under the frame platform, the conveying device is mounted on the frame platform, and the conveying device is matched with the tanks.

Description

technical field [0001] The invention relates to a cleaning method for extruding wire with brazing material and a cleaning device for realizing the cleaning method. The cleaning device belongs to matching cleaning equipment for brazing material processing. Background technique [0002] In recent years, with the application of brazing materials in high-end fields such as aviation, aerospace, nuclear energy, and electronics, higher requirements have been put forward for the quality and surface quality of brazing materials. However, how to improve the cleaning quality of the wire surface after ingot extrusion has always been an urgent problem to be solved. At present, the common method of cleaning the extruded wire is manual operation. Hand wash, rinse and blow dry. The manual operation method makes the extruded wire soaked in the acid solution for a long time, the soaking time is long and the efficiency is low; the surface quality after soaking and rinsing is uneven, which oft...

Problems solved by technology

The brazing material surface cleaning treatment device adopts ultrasonic cleaning, although the cleaning effect is relatively good, but due to the expensive ultrasonic equipment, it is not easy to realize large-scale cleaning in batches, and the brazing material surface cleaning treatment device adopts the process of adding alkali washing after pickling , which increases the use of chemical agents and increases the cost. In addition, the solder surface cleaning device uses a constant temperature numerical control cleaner to clean the liquid temperature in the solder surface cleaning device. The energy demand is huge, and the energy consumption is high. Conducive to energy saving and emission reduction
