Cleaning system and cleaning method for automotive metal plate stamping die

Abstract

The invention provides a cleaning system for an automotive metal plate stamping die. The cleaning system comprises a cleaning chamber, a bearing mechanism, a collecting tank, a sedimentation basin and a secondary filtering device. A spraying device used for spraying cleanout fluid to a die to be cleaned is arranged in the cleaning chamber. The bearing mechanism is used for bearing the die to be cleaned to enter and go out of the cleaning chamber. The collecting tank is located below the ground of the cleaning chamber so as to collect the cleanout fluid sprayed out from the spraying device. The sedimentation basin is used for pumping the cleanout fluid from the collecting tank, and a magnetic filtering device and an oil-liquid separating device are arranged in the sedimentation basin so as to carry out large-particle sedimentation, metal particle filtration and oil-liquid separation on the cleanout fluid. The secondary filtering device is used for pumping the cleanout fluid from the sedimentation basin and carries out fine filtering on the cleanout fluid to enable the cleanout fluid to be sent back to the spraying device. The invention further provides a cleaning method for the automotive metal plate stamping die. The cleaning system and the cleaning method can be used for eliminating the influence of excess component impurities on the filtering device in the cleanout fluid cyclic utilization process, so the cleaning effect can be better, cost can be lower and environment protection can be achieved.

Description

technical field [0001] The invention relates to the field of cleaning, in particular to a system and a method for flushing automobile sheet metal stamping dies with cleaning liquid. Background technique [0002] With the continuous intensification of competition in the automotive industry, higher requirements are placed on the performance and quality of vehicles. Stamping is the first process of the four major manufacturing processes of automobiles, and its production quality directly affects the quality of the body; and molds, as important process equipment for stamping production, are directly related to the quality of automobile sheet metal parts (especially outer covering parts). Automobile sheet metal stamping dies will not only wear out after long-term use, but also oil and iron filings and other impurities will remain on the surface, which will affect the surface quality of sheet metal parts. Therefore, in addition to the most basic maintenance of the mold on a regul...

Problems solved by technology

However, for automobile sheet metal stamping dies, their size is much larger than that of small products. The working environment of the workshop where the dies are located is harsh. When cleaning is required, a large amount of hydraulic oil, drawing oil, yellow Glycerin, workshop dust particles, iron filings, etc., plate blanking, torn scraps, etc. during the stamping process will also remain in the gaps of the mold. These impurities of different components will be mixed in the cleaning solution. If it is collected and filtered directly and returned to the injection device, first of all, the large particles and ir
