Abstract
The utility model provides a die applied to a stainless steel part punching process, which comprises a die holder and a flange molding embedded lump, and is characterized in that the flange molding embedded lump is of an alloy copper flange molding embedded lump being a tin bronze flange molding embedded lump. The die applied to the stainless steel part punching process adopts the flange molding embedded lump made of tin bronze, is simple and convenient in manufacturing process, and does not need heat treatment after processing as the face can be processed into a mirror face. The manufactured flange molding die embedded lump has the advantages of high hardness, high wear resistance, high corrosion resistance, easiness in cutting and processing, good brazing and welding performances, small shrinkage coefficient and no magnetism, the use time can be greatly increased, and the repair rate of processed stainless steel parts is reduced.
Description
Technical field
The utility model relates to the flange mould of using when producing stainless steel parts and inserts, and relates in particular to a kind of mould that is applied to the stainless steel parts Sheet Metal Forming Technology.
Background technology
The material hardness of stainless steel parts is high more a lot of than common cold-stamped part material, so this class part requires to be higher than too common cold stamping part to inserting of mould.Mould is for after pull and stretch, the deburring, adopts the method for various localized variation distortion, makes it reach the mould of the institute's shape and size of wanting requirement.Flanging die is the mould of the bore edges on the product or outer rim edge being translated into vertical edge, can be divided into two kinds of sky flange die and edge flange dies.Flange is mainly used in making assembling and the overlapping part with other parts, perhaps is used for processing specific shape for the intensity that improves part.Also can be used as control breaks or the means of wrinkle.The flange moulding of generally using is in the market inserted and is SKD11(Japan mould steel) be heat-treated to the 58-62HRC(Rockwell hardness) after carry out surperficial TD again and handle (processing of thermal diffusion method carbide coating).In the stainless steel parts production process, the TD coating that often occurs die insert in the piece in early stage comes off, and causes the part plucking, reprocesses technology together thereby cause to have more on the punching press flow process, reduces operating efficiency, influences yield rate.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, provides a kind of flange mould that need not carry out follow-up depainting processing to insert.
For realizing above-mentioned technical purpose, the technical scheme that the utility model is taked is: a kind of mould that is applied to the stainless steel parts Sheet Metal Forming Technology, comprise that die holder and flange moulding insert, and it is characterized in that: described flange moulding is inserted and is inserted for the moulding of alloyed copper flange.
As the further improved technical scheme of the utility model, the moulding of described alloyed copper flange is inserted and is inserted for the moulding of tin bronze flange.
It is easy to adopt tin bronze to make the flange mould processing technology of inserting, and minute surface can be processed in the surface, need not after the processing to heat-treat.The flange mould of making is inserted, and has high rigidity, high-wearing feature and corrosion resistance, easy machining, and soldering and good welding performance, constriction coefficient is little, and is nonmagnetic, can improve access times greatly, reduces the repair rate of processing stainless steel part.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 be Fig. 1 A-A to structural representation.
Fig. 3 is flange moulding insert structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, should be used for the mould of stainless steel parts Sheet Metal Forming Technology, comprise that die holder 1 and flange moulding insert 2, described flange moulding edge, 2 insert for the moulding of alloyed copper flange; The moulding of described alloyed copper flange is inserted and is inserted for the moulding of tin bronze flange.The stainless steel parts that the shape of mould is processed as required and deciding.
In metal, belong to the most wear-resisting of copper material again, and the too low very easily distortion of pure copper material hardness, if the hardness of using alloyed copper can improve copper can be improved some mechanical and physical performances of copper again, so finally select alloyed copper to insert as the flange moulding of this type of part.Through mould engineer's suggestion, it is the most suitable to choose tin bronze.
The scope of application of alloyed copper material: the alloyed copper material be used for have been made the slide block of guided mode behind high-quality stainless steel stretched mould, stainless steel roll, the automobile exhaust pipe, high-quality injection mould, compression mod and high velocity ram machine.Alloyed copper main feature: high rigidity, high-wearing feature.The alloyed copper material has hardness height (HRC30～55), the good advantage of density (7.5-7.8) anti-wear performance, and anti-wear performance surpasses the level of mould steel.Compare with punching block, biggest advantage is not pull product surface, significantly improves surface quality of products.Mould processing technology is easy, and minute surface can be processed in the surface, need not after the processing to heat-treat.
In sum, alloyed copper is occupied very big advantage, and tin bronze belongs to wherein a kind of of alloyed copper, is the higher class of hardness in the alloyed copper.
Tin bronze is to be the bronze of main alloy element with tin.The stanniferous amount generally between 3～14%, is mainly used in making flexible member and wear part.The stanniferous amount of distortion tin bronze is no more than 8%, also adds elements such as phosphorus, lead, zinc sometimes.Phosphorus is good deoxidier, can also improve liquidity and wearability.Leading can improve machinability and wearability in the tin bronze, and zincification can improve casting character.This alloy has higher mechanical property, anti-attrition performance and corrosion resistance, easy machining, and soldering and good welding performance, constriction coefficient is little, and is nonmagnetic.Coatings such as available wire flame spraying and electrical arc spraying method for preparing bronze bushing, axle sleeve, magneto-resistive element.Have higher intensity, corrosion resistance and good casting character, be widely used in for a long time in each industrial department.The mould that should be used for the stainless steel parts Sheet Metal Forming Technology has higher intensity, corrosion resistance and high-wearing feature.
