Stainless steel strain, many customers do tensile stainless steel have encountered this troublesome problem, ask yourself what you are drawing oil with it? If the stainless steel drawing oil is useless right, it is not surprising to have this problem. Of course, not to say that this question must produce stainless steel drawing oil and has a relationship, there are other aspects of the factors you one by one will be announced later.
Although because of the epidemic, many factories currently not yet started, there are some owners of the plant into operation ahead of their own, began to look for some better matching supply. This is not just received a customer's phone, saying that they are specialized in stainless steel stretching, there has been serious injury problems before, so down resulting in defective rate has been stubbornly high, at this situation is extremely severe environment, this is a fatal defect rate, I would like to solve this problem. Chinese New Year just when he heard about a friend, if the mold, material excluded under the premise of no problem, you can try to change professional drawing oil. He did not know before have dedicated stainless steel drawing oil.
Jiawei Ao combined with many customers before practice case, found that the stainless steel strain this problem is quite common, then how to solve the problem to reduce the strain tensile stainless steel encountered it? Because the problem is not just stainless steel drawing oil, also may be related to other factors.
1. The raw materials are drawn through the processing of raw materials for the outer, raw materials such as phosphate, spray or other exterior process, the material to be shaped outer mold constituting one non-metal layer, can greatly reduce or eliminate the workpiece the strain, this approach is usually higher costs and increased demand for other production equipment and increase of production processes, although this approach sometimes some role in practice rarely used in production.
2. between the workpiece and the mold, the molding material between the mold and add a layer of PVC film and the like, may also be treated strain doubt workpiece. About the production line through the organization to reach a series of thin film supply, and on the production cycle of stamping equipment, each producing a work piece to be added to a film, the impact of power production, this approach usually costs too high, it will produce a lot of waste, on small batch production of large workpieces such selection approach is desirable. Encountered a lot of customers to take this film before Jiawei Ao stainless steel drawing oil, they generally reflect the costs are too high, and some even have to manually remove a few spots from the surface.
3. After modification molds mold convex and concave mold material or mold convex and concave mold may choose the appropriate treatment for the outer mold material, so that the material is stretched and convex and concave mold touch properties such attack changes. Practice has proved that this is the way to deal with questions of economic strain and useful, and it is now widely chosen approach.
Stainless steel tensile strain in the relationship between oil and non-small! Do not ignore!
4 ... Before the issue ruled out stretching process, tooling, materials, stainless steel stretch there if your injury problems, Jiawei Ao recommends that customers may try to change professional stainless steel drawing oil, have sufficient lubricity, extreme pressure agent (lubricant Jia Weiao tensile steel are used in imported oil, oiliness agents, antiwear agents and the like, would be better), still can be maintained better lubrication at warming up state of the mold status. In the case of general oil continues to heat up the mold has lost efficacy lubrication, therefore, will produce strain, crack and other issues. Strain question can handle a workpiece.
In summary, the process and die tensile stainless steel workpieces convex, concave mold surface strain doubt many ways, specific to each customer's case, the possible responses are not the same solution, stretching comprises stainless steel oil not the same formulation, stainless steel drawing oil suggest that customers can use options based on the workpiece and the load size, production batch, the variety of the work material and the like. l5 &. & 973. & 99O
