Description

A kind of cold punching die releasing agent for lifting demoulding efficiency
Technical field
The invention belongs to releasing agent manufacture field, and in particular to a kind of cold punching die releasing agent of lifting demoulding efficiency.
Background technology
Cold stamping is at normal temperatures, pressure to be applied to plate or hot material on forcing press using stamping die, it is produced modeling Property deformation or separate so as to obtain a kind of pressure processing method of the part of required shape and size.Cold stamping includes two substantially Operation：（1）Separation circuit：Stamped workpieces are separated from each other with plate along desired contour line；（2）Forming process：Blank not by It is plastically deformed under conditions of bad, shape needed for obtaining, the processing method of size and precision.In order that the casting after must being molded It is easy to depart from, often needs to use releasing agent, releasing agent is a kind of feature processing aid for playing auxiliary disengaging effect, and it is in Between mould and moulded products, it is prevented from rubber, resin, the product of metal material and glues on the mold surface.In industrial production In, in order to weaken the adhesion between product and mould or absorption, generally using coating releasing agent in die surface, product connects with mould Dielectric film layer is formed between contacting surface, the thicknesses of layers is only micron order, and heat endurance is good, the film that is effectively isolated of formation can be with Die surface is formed and is connected chemically, and isolates mould and product, so that peeling force weakens, allows profiled part quickly to take off easily Fall.Presently commercially available organosilicon polymer is optimum releasing agent, but it is during use, easily produces acid Matter, and then corrode metal surface, therefore it is badly in need of a kind of new high performance releasing agent of research and development.
The content of the invention
In order to solve the various drawbacks of existing releasing agent, the present invention provides a kind of lifting demoulding efficiency, wide using scope Cold punching die releasing agent.
The present invention is achieved by the following technical solutions.
