Problems solved by technology

However, since the hard mold and the relatively soft blank to be processed relatively slide during the stamping and stretching process, the plastic deformation occurs on the entire blank including the contact surface, and the contact surface between the blank and the mold is very large, so it is difficult Forms a continuous fluid lubricating film over the entire friction surface
At present, the lubricating oil used in the stamping and stretching of galvanized steel sheets is due to problems in the selection of effective components and proportions, resulting in the formation of lubricating oil between the punch and die surfaces of the stamping die and the contact surface of the workpiece material. The oil film is difficult to be continuous and has poor adsorption. Under the strong stamping force, the formed oil film is easily damaged, so that the part of the plate and the mold may be in a dry friction state, which not only makes the surface of the stamping workpiece easy to scratch, but also the plate. The surface is easily oxidized and rusted (pit corrosion and spot corrosion, etc.), the smoothness and brightness decrease sharply, which brings troubles to the subsequent phosphating and spraying processes and seriously affects the appearance quality of the product; at the same time, it also intensifies the wear on the mold , affect the service life of the mold, increase the production cost, prolong the production cycle, and the manufacturer suffers a large economic loss

Abstract

A galvanized steel plate punch stretch lube oil consists of motor oil 45-55wt%, castor oil 2-4wt%, soya oil 25-35wt%, mersolates 0.5-1.5wt%, zinc naphthenate 0.5-1.5wt%, triethyl phosphate 2-4wt%, chlorinated paraffin 3-5wt%, butyl-octanol zinc salt phosphinothioyl 2-4wt%, poly-n-butyl vinyl ether 4-6wt% and bactericide 0.2-0.3wt%. The process is carried out by adding motor oil into reactor, heating to 90-100degree, agitating at 750-850 / min, adding into mersolates, zinc naphthenate, chlorinated paraffin and triethyl phosphate successively, agitating for 1.5-2.5hrs, lowering temperature to 50-60degree, adding into castor oil, soya oil and bactericide, agitating for 0.5-1.5hrs, lowering to normal temperature, adding into butyl-octanol zinc salt phosphinothioyl and poly-n-butyl vinyl ether, and agitating at 75-85 / min and agitating 1.5-2.5hrs. It has better oil-film continuity and adsorption and prevents punch work-piece from being scraped and corrosion.

Description

Technical field: [0001] The invention relates to a lubricating cooling liquid for stamping process and a production method thereof, in particular to a galvanized steel stamping drawing lubricating oil capable of preventing scratches and corrosion on the surface of stamping workpieces and ensuring surface smoothness and a production method thereof. Background technique: [0002] Stamping processing, also known as sheet metal stamping, is a method of processing parts of a certain size, shape and performance by applying pressure to the sheet through a mold to separate it or produce plastic deformation. During the stamping process, the metal material produces plastic shear deformation. If there is strong friction between the shear surface and the working surface of the mold, the local high temperature will cause "welding" and adhesive wear. Lubricant for cooling and cooling, in order to form a pressure-resistant, heat-resistant and tough lubricating film on the metal surface, se...
