Description
Technical Field
The invention relates to the technical field of plate stamping, in particular to a lubricant suitable for plate stamping forming.
Background
The stamping forming is a common mechanical processing method, and stamping parts produced by stamping processing are widely applied. The press working has high pressure and low speed, and the friction surface is in a mixed state of fluid lubrication and boundary lubrication, and dry friction can exist locally. The stamping forming has the advantages that: high material utilization rate; parts with thin walls and complex shapes can be processed; the interchangeability of the stamping parts in the aspects of shape and size is good; parts with light weight, high strength and good rigidity can be obtained; high productivity, simple operation, and easy realization of mechanization and automation.
In the manufacturing equipment industry, the plate needs to be subjected to cold-plastic punch forming processing, and the obtained cold-plastic punch forming part has a bright, perfect and lossless metal surface. In the process of stamping, the required stamping force is large, and the basic premise of ensuring that the stamped and formed part is not broken is stamping technology. In addition, the punching machine can bear the punching force, and the long service life of the equipment is ensured. In the stamping process, stamping lubricant is coated on the surface of the plate, and the stamping lubricant has the functions of generating hydrostatic pressure in the concave part of the surface of the plate, reducing the contact area, keeping the oil film intact on the convex part without breaking, forming a thin lubricating film with small shearing resistance and keeping the friction at a lower level. The plate stamping process comprises stamping and shearing, stamping, punching and the like, and the pressure which gives the stamping die of the stamping die several times higher than the strength of the material is utilized for stamping. The production efficiency is high, the quality is good, but good lubricating and cooling oil is needed to ensure that the section is smooth and clean, and simultaneously the service life of the punching tool is prolonged and the cutting edge degree is kept. In addition, due to the harsh local processing conditions, lubricants are required to have suitable viscosity and good extreme pressure properties; the friction force is reduced to make the deformation of the whole punch part uniform and improve the limit.
Disclosure of Invention
The invention aims to provide a lubricant suitable for plate punch forming, which integrates multiple functions of cleaning, lubricating, rust preventing, degreasing, cooling, die sticking and the like.
The invention provides a lubricant suitable for plate punch forming, which comprises the following components in percentage by mass:
1-5% of a surfactant, wherein the surfactant is naphthalene sulfonate;
2-10% of silicone oil;
1-2% of a tackifier;
30-35% of organic alcohol;
5-10% of polyacrylamide;
1-2% of phosphate;
50ppm to 80ppm of graphite, wherein the average particle size of the graphite is 2 to 5 mu m;
0.2-1.5% of corrosion inhibitor, wherein the corrosion inhibitor is a mixture of organic sodium salt and inorganic sodium salt;
the balance of water.
In one embodiment, the tackifier is sodium salt of hydroxymethyl cellulose.
In one embodiment, the organic alcohol is polyethylene glycol.
In one embodiment, the corrosion inhibitor is a mixture of 50-40% by mass of sodium benzoate and 50-60% by mass of sodium nitrite.
In one embodiment, the phosphate is dipotassium hydrogen phosphate.
Compared with the prior art, the lubricant suitable for plate punch forming provided by the invention has the following remarkable effects:
the lubricant is a water-based lubricant, and has good wettability and adsorbability to workpieces through creative component proportion, so that the lubricating performance is improved, a protective film is formed in the stamping process, and the lubricating effect is effectively achieved. In addition, the lubricant has good lubricating property and good antirust property through creative component proportion. In addition, the lubricant is convenient to clean, greatly reduces the labor intensity of cleaning, and enables the workpiece to have good smoothness.
The lubricant suitable for plate punch forming provided by the invention is added with ultrafine graphite, and small-particle graphite is easier to introduce into a friction interface and has better lubricating property. Graphite is a solid lubricant with a low coefficient of friction
For sheet materials, the viscosity of the lubricant has a very large influence on the lubricating effect. The invention selects hydroxymethyl fiber sodium salt as the tackifier of the lubricant, which is water-soluble cellulose ether, can control the viscosity of most common aqueous solution preparations to be changed between 0 and 900CP, and can adjust the viscosity of the lubricant by adjusting the addition amount of the hydroxymethyl fiber sodium salt.
The use of surfactants is a very important step in the formulation of water-based lubricants. The function of the lubricant is to evenly disperse various components in the lubricant in a matrix so that various additives in the lubricant can normally play the original functions according to the proportion. The surfactant is naphthalene sulfonate, so that the use is convenient and simple, and the graphite can be uniformly dispersed in the matrix.
The lubricant matrix is used for smoothly conveying various lubricating substances in preparation to the contact surface of a plate and a stamping die to realize the purpose of lubrication. Other components include silicone oil, organic alcohol, polyacrylamide, phosphate and corrosion inhibitor. The phosphate can generate electrochemical reaction with the metal plate to generate a phosphating film, and has strong adsorption effect on the surface of the metal plate. In addition, the silicone oil is a very good adhesive, the adhesive force of the lubricant and the metal plate substrate is obviously improved, and a uniform lubricating film can be formed on the surface of the metal plate substrate.
Compared with the prior art, the lubricant suitable for plate punch forming provided by the invention takes water as the base body of the lubricant, and not only retains the advantages of wide source, low cost, stable chemical property, difficult decomposition, no toxicity, no odor and the like of the common water-based lubricant, but also overcomes the problem of poor lubricity and adsorptivity of the water-based lubricant, and has very considerable application prospect.
